O alumínio é um dos metais que possui reciclagem infinita, podendo ser reprocessado infinitas vezes, resultando no produto conhecido como alumínio secundário. Os processos de obtenção desse produto demandam de grandes investimentos e não são acessíveis aos pequenos e médios produtores do início da cadeia de produção do alumínio. Tendo em vista a necessidade de desenvolvimento de uma tecnologia mais acessível financeiramente e a produção de alumínio secundário na forma de lingote que viabiliza sua exportação, por exemplo. Assim este trabalho se dedica, com sigilo de invenção, a apresentar e descrever a montagem do aparato experimental utilizado para produção de lingotes de alumínio secundário a partir de sucata de alumínio, produzidos por um processo de fundição otimizado a gás (forno a gás GLP). Os principais resultados encontrados foram as mudanças conceituais e a técnicas utilizadas no aparato experimental construído, usando gás GLP a baixa pressão e vazão para obtenção do lingote de alumínio secundário, permitindo que a tecnologia desenvolvida possa ser acessível a pequenos e médios produtores do setor

Em um cenário competitivo, o monitoramento da variabilidade do processo está associado as falhas nas análises do empreendimento para avaliar o desempenho dos processos até o final do produto, dando assim a importância do CEP para detectar e diminuir essa variabilidade, garantindo maior conformação além de redução de custo, fazendo com que a empresa se torne mais competitiva. Dessa maneira, o presente trabalho buscou analisar dados reais de um processo de produção de odorizador em gel aplicando gráficos de controle para variáveis (  e S) gerados pelo software Minitab® e a comparação com a lógica Fuzzy pelo software Infuzzy com a finalidade de reduzir a variação no peso do produto. A metodologia adotada consiste no mapeamento dos dados, em que se obtém uma matriz estimada da coavariância, a qual se utiliza para construção dos gráficos de controle propostos com a comparação da lógica difusa. O resultou mostrou que o processo de fabricação de odorizador em gel está fora de controle estatístico onde o valor de p – valor é igual a 0,005, as causas de variação da qualidade interferem no controle estatístico do processo e o nível de PPM é aproximadamente 89%, fazendo com que o processo de produção referente aos dados coletados está fora de capacidade do processo, isso foi comparado com o número de defusificação da variável peso com o valor de 8,1, igual ao valor da LC do CEP 8,133 que mostrou ser eficiente o uso das duas metologias.

The objective of this work is to validate a new process for manufacturing motorcycle parts that have a high added value (R $ 1.82 / motorcycle). For this, an exclusive group was set up to deal with such activities, where the case study methodology was used and through it a workflow was guided, contemplating technical study activities, visits to suppliers, alignment meetings, testing applications and implementation of proposals. This study resulted in the raising of some proposals, where it was decided to opt for the proposal that would mitigate the cost reduction and waste of raw material, that is, application of the sintering process in motorcycle parts currently stamped. After the implementation of the new process, the results point to a considerable reduction in the cost of production of the parts (R $ 0.64 / motorcycle), totaling R $ 463,000.00 / year, considering the simultaneous application in other models, as well as considerable reductions in waste of raw material.

Believing in the great potential of the North region of Brazil, we started a research project that highlighted the Amazonian raw material, in this context, for beer production. Amazônia Pale Ale (AmPA) was conceived as a light and refreshing beer, with low bitterness, having as its differential the wild Amazonian yeast. The basic formulation started with barley malt, hops and a wild yeast isolated from cashew apple, evaluating the physicochemical and sensorial characteristics. Cajuaçu is a native and dispersed species in the Amazon, from Maranhão to Mato Grosso and Guianas. in Pará, specifically in Bragança, widely consumed in the period from January to March, the harvest period. This fruit is used for home production of an alcoholic fermentative mixed drink that takes vodka and honey. We submitted the cashew nectar to various culture media, where we found 38 colonies. All samples were tested until choosing the one with the highest potential. Sample C4 was the strain with the best performance in an isolated test on AGAR, so it was isolated and reproduced for continuation of the process. The must was submitted to the steps of brazing, filtering, boiling, cooling and clarification, followed by the inoculation of C4 yeast. The yeast was submitted to a yield test, and after 72 hours in a fermentation test under constant agitation, in a temperature variation between 20 C to 25 C, it reached several density (all corrected by the temperature x density table), we reached a yield of 46.67%, reaching a maximum alcohol content of 5.51% alcohol or that is, approximately 46.6 g of alcohol obtained from 100 g of fermented sugar, representing an efficiency in the fermentation process of 81.27%. These results are consistent with those found in the literature, since according to Hashizume (2001), even under optimal working conditions, the highest yield in alcoholic fermentations does not exceed 48%, and, in the industrial process, the yield is even lower. With the yeast chosen and tested, we go to the production of beer. To propose an Amazonian beer, we need to have a base to give the initial “start”, and what has the face of refreshing and tasty beer, which has the greatest characteristics of our Amazon, so we used what was easily accessible, such as spices and fruits. The yeast of Amazonian origin fit perfectly into the proposed style, therefore, showing all the strength and complexity that was expected. For the production of AmPa, we started with a beer of the similar style that we are looking for, so we characterized a light APA, with few hops, and without any spices, so that we could analyze the behavior of yeast in a craft beer. In addition to all that has been said, it has a more acidic character, and this can be obtained in several ways. The first could be brazing, making a “sour mash” (acid brazing). Fermentation took place at 20 °C for 7 days. The beer was aged at 2 °C for 8 days, and then bottled and pasteurized. After the elaboration process, 7 days after the beers were analyzed sensorially. It was concluded that there is a possibility of success in the use of wild Amazonian yeasts for the manufacture of beers, creating a unique characteristic, without the presence of off flavor, thus meeting the demand for new biodiversity products linked to the sustainable valuation of biomes and adding even more plus the brewery guides.

This work addresses to identify and reduce Occupational Risks in a hospital laundry using Quality Management tools with the implementation of the Problem Analysis and Solution Method (MASP). Bibliographic research was carried out, as well as interviews with employees and managers of that hospital. The survey was carried out from January to June 2020, concurrently with the Coronavirus Pandemic (Covid-19). In the Methodology, the steps of Identification, Problem Observation, Analysis, Action Plan, Verification, Standardization and Conclusion were carried out. With the application of the Quality tools at MASP, there were 2 main occupational risks in the stages of washing the contaminated layette: risks of accidents and biological risks and, to a lesser extent, physical risks, mainly due to the obsolescence of machines and equipment, adaptation of the laundry only partially to NR 32 and RDC 50/02 and, in addition, lack of harmony between the activities of the Surgical Center and Laundry. A 5W2H action plan was prepared to mitigate these occupational risks.

This work aims to use the SWOT matrix for the optimization of logistics processes, to achieve these objectives, qualitative analyzes were used through data collection according to the steps measured in this work. Constantly understanding the variables and implications of the business scenario leads us to propose a complete mapping of the current situation of the organization, raising the points of non-compliance that affect the business result. The organization's raw material stock, where the high rate of stopped material was identified through the SWOT methodology, Identifying loss indicators and proposing improvements to optimize this process in the organization leads us to understand that large organizations still do not apply a tool for analysis let their income fall, thus affecting profitability, as the stock of a manufacturing company represents about 80% of operating costs, so from this research we have as a result when analyzing data provided, that the stock of stopped material, without use and without control to meet customer demand represents about 5% of financial loss. In this way, we came to the conclusion that the SWOT analysis helped to optimize processes and implement continuous improvements that add gains to the organization.

The use of a model in a simulated environment that represents the adsorption process dynamics in a fixed bed column, is presented as a means of evaluating scenarios before the elaboration of a full-scale project. This research adopts the mechanistic approach using a model capable of providing more detailed information of an adsorptive bed, such as axial dispersion and mass transfer in the solid phase. The mathematical model composed of a system of differential equations was solved using the Method of Lines. Convergence analysis was applied to estimate the number of mesh discretization, resulting in a low computational cost. Bayesian inference was employed using the previous knowledge of the phenomenon together with experimental measurements and uncertainties. Markov Chain Monte Carlo was adopted to obtain the estimates and implemented according to the Metropolis-Hastings algorithm. To evaluate the results, mean and standard deviation of the priori probability distribution and the influence on the estimates were observed, as well as the influence of the increase in uncertainties on the acquisition frequency of simulated measurements. The estimates reveal that information obtained at the exit of the bed can be used to predict rupture curves at other points in the column where measurements are not available. Thus, the proposed method presents itself as a robust alternative for parameter estimation.

Considering the current situation of the global economic crisis and globalized competition, it is necessary to reduce cost and improve productivity in industrial activities. In this context, logistics in general stands out as a source of opportunity for organizations to establish competitive advantages. In this respect, the present work seeks to highlight the contributions that the Milk Run System can bring to the improvement of the flow of materials in the supply area and with the work in partnership with its suppliers, allowing cost reduction through changes in logistics operations. The work was developed in a multinational company manufacturer of electronic parts for the 2 and 4 wheel poles, located in the city of Manaus. The study showed that by replacing the conventional system with the Milk Run system, the company is able to improve delivery rates. In the case study, the work was carried out in the four suppliers with the highest volume of cargo, in which it was creating routes and delivery times that best met the interests of the company and suppliers.

The jig equipment responsible for the function tests are complex and highly capable machines used in the electronics industry to validate the functionality of analogic and digital devices or any other product of electronic factories of the industry pole of Manaus. In the studied process, those machines are operated in a series configuration, and the effect of a failure in this type of configuration is very critical, as the simplest failure can impact the production process and generate losses for the company. This work aims to assess the behavior of test equipment in a cable modem and set top box production processes, to make analysis of the failures happened during this production process, to guide a reliability study that enable the maintenance manager to make decisions about how to deal with equipment aiming to reduce failure rates and use proper maintenance practices to allow reliability to be maximized.

The sales forecasting process has been structured over time with new technologies and tools, for data consolidation and handling. The companies, which previously had no focus on the sales forecasting process, were not impacted by the lack of it, but currently, adjustments are necessary for its insertion, because there is consensus that only intuitivity, usually directed by past experiences or subjectivities, or optimized results or underestimated them. Walking in the above, this research aims to identify a sales forecast model appropriate to the portfolio of a medium-sized beverage company. In the study of this dissertation, the explanatory research technique was applied with exploratory and descriptive analyses, and minitab® and Excel software was also used® to perform the analyses through statistical abstracts, tables and figures, so that there was the assertive choice of the model to be applied to the business. Qualitative and quantitative forecastmodels, graphic analysis, residue scans and forecast error calculations were evaluated. The mean deviations and MAPEs (Mean Absolute Percent Error) of the models were compared: moving average, exponential smoothing, linear trend and holt winter and, as conclusion, the models with the lowest prediction errors were: moving average N=2 with MAPE=14.8%, exponential smoothing with MAPE=15.2% and linear trend with MAPE=15.4%. The choice was for the exponential smoothing model, although not the slightest error is easy to apply and weights the historical data.

Estimating solar radiation is important for various segments of society such as agriculture, meteorology and electricity generation (photovoltaic systems). This work aims to estimate the Global Solar Radiation in ten cities in the state of Pará - Brazil, using estimation models, Hargreaves-Samani and Bristow-Campbell, using meteorological data provided by Automatic Meteorological Stations, belonging to the National Institute of Meteorology (INMET), to compare the observed and estimated values and analyze which model best fits the region, through the parameters Coefficient of Determination (R²), Willmott Index (d), Pearson correlation coefficient (r) and Relative Root Mean Squared Error (rRMSE). The results showed that the models are satisfactory and can be used to estimate the Global Solar Radiation, however for the less rainy period there was an overestimation, between june and november. The Castanhal station had the lowest average global solar radiation compared to the other stations with an average daily radiation equal to 15.06 M/m².day, while the city of Redenção had the highest daily average, 18.33 MJ /m².day.  The city of Tomé Açu presented better fit of the models referring to the observed values, since for the HS model, the confidence index was considered very good, c equal to 0.78, and the relative RMSE was considered excellent, with rRMSE equal to 9.93%. For the B-C model for this station, the confidence index and the relative RMSE were considered good, c equal to 0.71 and rRMSE equal to 19.14%.

In this study, the Bayesian Monte Carlo technique via Markov Chain (MCMC) was selected to estimate the parameters of the differential equations of the SQUIDER3 and SEIR4 compartmental models, seeking to reflect the propagation of Covid-19 in the state of Pará. An algorithm was developed in Matlab, reproducing the MCMC technique that uses stochastic processes and simulates a random selection of values of each parameter. When sampling proportionally to the probability of the values, a probability distribution was reached in order to be able to both adjust the model parameters and converge to the stationary distribution of interest. The parameters estimated in this paper for the SQUIDER and SEIR compartmental models were compared to real data using the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) metrics. Both of these were applied for a better definition of the model that best represents the Covid-19 propagation phenomenon in the state of Pará. As a result, histograms were obtained that indicate a convergence of parameters in the SQUIDER model, which did not happen in the SEIR model. By applying the AIC and BIC, it was demonstrated that the SQUIDER model was the best model to represent the phenomena (i.e. the propagation of Covid-19 in the state of Pará), and has the potential to be used as a predictive model.

The progressive use of power electronic devices, connected to the electrical system, has contributed to the increase in problems caused by harmonic disturbances in electrical networks. Thus, this work aims to develop a methodology to analyze harmonic impacts on electrical networks caused by non-linear loads using the Decision Tree technique. The model used was the regression tree through the use of the Classification and Regression Tree (CART) algorithm, which relates the harmonic current of a non-linear load and the harmonic voltage at the common connection point of the electrical network. The technique used was applied in three case studies in order to show the validity of its application in solving problems that seek to investigate the dependence relationship between two variables. In case study 1, the DIAL2-19 feeder contributes the 3rd harmonic impact factor for phase A with 43.587%. The DIAL2-16 feeder contributes with an impact factor of 36.407% for phase B. For phase C, the DIAL2-17 feeder contributes with an impact factor of 26.434%. For case study 2, the DIAL2-17 feeder contributes with the 5th harmonic impact factor for phases A and C, with 50.257% and 52.319%, respectively. The DIAL2-16 feeder contributes with an impact factor of 39.697% for phase B. In the case study 3, the DIAL2-19 feeder contributes with the impact factor in the 7th harmonic for phases A and C with 30.058% and 25.950%, respectively. The DIAL2-16 feeder contributes an impact factor of 48.891% for phase B.

This work aimed to analyze the impacts generated by the Amazonian cost in public purchases on a campus of the Federal Institute of Education, Science and Technology of Amazonas (IFAM). The investigation had an exploratory and descriptive purpose, structured by the case study method with a quali-quantitative approach. In the qualitative phase, the external factors in the procurement process that affect the performance of IFAM's institutional actions were evaluated. At this stage, data were obtained through documentary research, application of an open questionnaire to servers linked to the purchasing sector and a semi-structured interview with the director of the researched unit. Quantitative data were obtained from the Government Procurement Portal - COMPRASNET and evaluated with descriptive statistics to analyze the costs of purchases made by a campus in the capital and an IFAM inland. The results of the analysis indicated mainly that the logistic factor is the main responsible for the differences in the practices of prices practiced between the units present in the city of Manaus and São Gabriel da Cachoeira, where the latter presents a certain precariousness in the process of purchasing materials.

Most companies don't use data as an asset and turn it into large, costly liabilities, data alone has its value, but the ideas and applications generated through it substantially increase that value. Within this context, the possibility arises of developing a process of using the data to generate measurable economic benefits, contributing to new sources of revenue and internal improvements. And to measure and indicate whether the organization would be at the appropriate time to develop such a process, it is proposed to develop a conceptual model to assess the analytical maturity for data monetization, through the combination of factors related to the analytical context and the digital product. Comparative analyzes of the factors that made up the proposed model were carried out, based on a bibliometric survey. A system to measure the maturity level was developed using the approximation coefficient of the multicriteria decision support method called TOPSIS. And to validate the proposed model, an evaluation of a case study (Brazilian technology company) was carried out, which obtained an average maturity level of 33% for data monetization.

The main objective of this work is to evaluate the impacts of Quality Control Circles (CCQ) on the engagement of employees of a multinational in the mining sector, based on the premise of long-term continuity of the program.

This process will help the company to deliver products that fit the organizational strategy.

The corrugated cardboard packaging industries represent a high polluting capacity by using inks in their conventional manufacturing processes. In turn, the treatment of the effluent generated in these industries must be efficient, in order to promote the removal of the pollutants that make up the paints, preventing them from reaching the receiving bodies. Because, when incorporated into the water supply, they offered health risks. In order to mitigate these risks, the present work proposes to identify, through a diagnosis, to increase the efficiency of the current system adopted by the industrial effluent treatment station (ETEI) of a corrugated paper industry, with the purpose of increasing the quality of the final effluent, as well as reducing the cost inherent to the disposal of solid waste generated by the treatment (sludge). Structural physical interventions were carried out, such as the installation of access stairs and expansion and maintenance of tanks, collections at the inlet and outlet of the system for analysis of the physical-chemical characteristics of the raw and treated effluent. With the implementation of the system optimization proposal, there was an increase in the speed and daily treatment capacity, which allowed reducing the accumulation of raw effluent in the reservoir. The physical-chemical analyzes of the treated effluent showed that all the parameters studied, including the legally established DBO and DQO, were achieved with the treatment, making it possible to comply with the CONAMA resolutions 357/05, Art. 34 and CONAMA 430/11. In addition, there was, on average, a decrease from 71% to about 10% of the final sludge moisture and, consequently, a significant reduction in disposal costs.

Currently, these demands have been expanded and, in addition to cost, quality, delivery speed and flexibility, a market is identified that starts to charge for the reduction of environmental impacts generated by products and processes. Having as a problem the factors that cause the loss of stability, it is possible to list the failures or breakdowns of operational equipment and these can occur for several reasons. With the general objective of applying Lean tools in a PPCM process. This research adopted the case study for its development, the case study indicates principles and rules that must be observed during the investigation process.

Environmental problems accentuated by fires and fossil fuels reflect the need to develop more accurate environmental monitoring systems, as well as the reuse of waste heat in thermoelectric conversion in industrial processes. Thus, in this research, thermocells based on Buckypaper (BP) were developed in two arrangements: layered and coplanar. BP was produced by vacuum filtration of functionalized Carbon Nanotubes (f-CNTs) through a filter paper with 14 μm pores. Scanning Electron Microscopy showed a BP consisting of cellulose fibers impregnated with agglomerated f-CNTs. By measuring two-point, a BP tape (1.0 cm2) showed an electrical resistance of 0.92 kΩ at 300 K. When heated in the range of 300-337 K, the BP reduced on average 22.39% of its electrical resistance, characterized as a thermoresistor. In the layered thermocell, keeping the copper electrode at room temperature while the BP electrode (active area: 5.5 cm2) was thermally excited generated a thermoelectric power (α) of 26.33 mV/K for ΔT = 3.0 K. This result is superior to that reported in nanostructured thermoelectrochemical cells and is close to that obtained by commercial silicon. In the coplanar thermocell, the BP was connected between two copper electrodes that acted as hot and cold sides (cooled by a heatsink) and reached α = -0.06 mV/K for ΔT = 19 K. This result was inferior to that obtained for Bi2Te3 and superior to that obtained by a free-standing BP based on nitrogen-doped CNTs.

Public services imported a range of performance management techniques and instruments to increase the efficiency and quality of processes and services and the transparency of results, including rational planning, target setting and budget control, lean management and performance measurement. Law No. 13,240/15, which deals with the administration, disposal, transfer of property management from the Union and its use for the constitution of funds. Most public sector organizations are facing increasing scrutiny amid calls for greater accountability, monitoring and control. Thus, the objective of this dissertation is to analyze the failures of the transfer process, in the last 5 (five) years, as well as to quantify the amounts not transferred to the states. The first stage of the research consisted of a literature review. Content analysis was developed in three phases: first, a previous analysis was carried out; subsequently, the choice of documents and information obtained from the databases of the Secretariat for Heritage of the Union (SPU) was made and, finally, the material was explored with the proper interpretation of the data and discussion among the authors. The results show, as the main failures, the discontinuity of the municipalities' administrations in the disclosure of information from the Plants of Generic Values – PVG to the Regional Superintendencies of the Union's Patrimony Secretariat until 06/30 of each year; in the cataloging and sent the PVG data to the Regional Superintendencies to the General Coordinator of Heritage Assessment and Accounting – CGCAV/SPU/ME. It was found that some Regional Superintendencies either sent wrongly the list of municipalities with rights or sent updates of the PVG from previous years; sending of data (CNPJ and Current Accounts) incomplete or with divergences by Banco do Brasil; in the process in the General Coordination of Collection in the Preparation of Municipalities with Rights to Transfer; in the process in the General Coordination of Collection of Payment in the Integrated Administration System - SIAFI. It is concluded that, in addition to introducing an important improvement in the process of monitoring heritage revenues, the tool allowed us to estimate the amounts to be transferred to the Municipalities as established in art. 27 of Law No. 13,240/2015, which amended Decree-Law No. 2,398 of 12/21/1987 with the inclusion of art. 6-B.

This article presents a study that consists of a fuzzy inference model specification for the evaluation of heat agents. The structure of model fuzzy used were inputs measured temperature and metabolic rate, while the output was work environment condition that could be salubrious or insalubrious. Through, the inference rules established and according to Brazil legislation about heat, Occupational Hygiene Standard 06, the proposed model can determine the worker conditions about the heat. The validation process is done in three industries from the Industrial Pole of Manaus, therefor all the process necessary for preparations to use the proposed model was described to obtain all the variables necessary in the field. As a result, the proposed model got the correct classification of work environment conditions with pertinent results according to current legislation and technical expertise.

With the globalization of markets, there has been a considerable increase in global competitiveness, which imposes on organizations the continuous search for new management tools, such as in the area of occupational health and safety. Regulatory Standards (NRs) can be defined as the set of technical provisions and procedures related to worker health and safety (OSH) in a given activity or function. These NRs, being well analyzed and used, allow companies to offer safe and healthy working environments and conditions to their employees. Based on the scientific point of view, it is necessary for companies to carry out an adequate study to assess how compliance with the NR`s is, because from them it is possible to adapt the organization to labor legislation. Therefore, the motivation for preparing this dissertation is explained due to the need to understand more about the NRs related to Safety and Health at Work (OSH) in a company in the telecommunications sector that is standardization. Due to this need, the objective of this paper is to analyze the compliance with regulatory standards related to Safety and Health at Work in a company in the telecommunications sector, in order to avoid possible fines by the Ministry of Labor. The research was classified as exploratory and a case study. The data sources needed to carry out the study were: field research, bibliography, and direct observational analysis. By carrying out the checklist of telecommunications company X, it was possible to identify and analyze the critical points found in the audit through the Pareto Diagram quality tool, in which the main irregularities and potential fines that the company can pay for non-compliance were verified. of NRs. The irregularities evidenced the existence of several non-compliances in the company, through the infractions stipulated in NR-28, the potential risk of a fine was calculated at R$816,338.66, converting this result into a Pareto chart, within the four infractions, it appears that only infraction 3 is responsible for most of the items in non-compliance, which represents a potential risk of a fine of R$ 464,466.94. Based on percentage calculations, it is pointed out that infraction 3 represents 57.90% of the total that the company can pay for non-compliance. In other words, the violation of this infraction should be the priority because it represents the greatest potential risk of a fine for telecommunications company X. Considering the need to mitigate the non-compliant items of the 21 NRs applicable to telecommunications companies, actions to be taken were proposed, which was presented by the SW2H tool, for the standards (NR-7, NR-9, NR-10, NR-15, NR-17, NR-33, NR-35) that most influence the results of the aforementioned company. Therefore, with the analysis of the NRs in telecommunications company X, proposed solutions were carried out through an action plan, presented in full in Appendix B, to regularize and adjust the NRs that are shown in the result of this work.

The objective of the research is to evaluate the applicability of the DMAIC methodology - Define, Measure, Analyze, Improve and Control, or: Define, Measure, Analyze, Improve and Control and other quality tools in the correction of non-compliance problems related to the execution of projects in the housing construction of the My Home, My Life Program. To analyze the current situation, the parameters and criteria of control in the works and the forms of treatment of non-conformities that occurred in the construction of the My Home, My Life housing complex in the cities of Itacoatiara and Manacapuru in the State of Amazonas. As for the results, the research demonstrates that the use of the DMAIC method allows to improve procedures and techniques in a project, resulting in continuous learning, which is one of the bases for improving the quality of processes and a requirement for its reproducibility. The use of the method allows achieving both the improvement of the performance of the processes, in the execution phase of the work, as in the subsequent phase, as it presupposes the concept of correction of non-conformities as a continuous process, analytically based and subsidiary to the corrective measures adopted. Permanent control allows not only to avoid new non-compliant situations, but also to develop a database that enables the constant improvement of performance monitoring processes and methods. In this way, through the feedback of the process to other projects, it is intended to reduce the rate of construction pathologies in order to encourage continuous quality improvement in Civil Construction housing projects.

The planning and programming of major maintenance or general reviews (Major Overhaul) aims to identify needs, coordinate activities and plan resources. Detailed and efficient planning provides compliance with the deadlines and optimal maintenance criteria allowing the equipment to be maintained with minimal incident or accidents, thus avoiding the occurrence of large operational and financial losses for the entire plant. Thus, the present work was structured in the type of exploratory research that aimed to understand the standardization of planning and scheduling processes of a large maintenance stop of the bauxite mill that is inserted in the Bayer process, alumina's production process, using a planning and control tool. It sought to carry out preliminary studies, aiming at structuring the context. The results obtained from the development of this work affirm that project management to obtain control over maintenance is the best way to improve and quality, once effectively performed, maximizes the reliability and predictability of prevention and correction actions, safety, as well as the resources necessary for the execution of these actions. Another factor of great importance is the gains from mappings and controls, whether from planning deliveries, resources and documentation. Thus, from the development of this research it was possible to collect a set of lessons learned to be used in the next major industrial maintenance stops, as well as the opportunities difficulties in performing pre-stop activities of the equipment, occurring some delays and also the inclusion of some activities and improvements during the project.

For a long time, Industrial Maintenance was considered a cost, naturally unwanted, by asset managers; however, today it is a strategic part and represents a high investment in the world's largest industries. This Maintenance is part of a relatively recent concept, but growing in the industrial environment, called Asset Management and some of its pillars are Reliability and prediction techniques of equipment's operational conditions. In this study, failure data were obtained during 5 (five) years of operation of 6 (six) hydrocarbon centrifugal pumps and from this history the most recent Reliability, Availability and Predictive Oil and Vibration Analyzes were studied. Evaluating several compound parameters in the universe of maintenance and reliability as well as determining which are the priorities of the responsible team, taking into account the operational perception of each component of this team, becomes a complex mission under the human point of view. This complexity is why it was important to use Artificial Intelligence, capable of relating purely subjective qualitative assessments to objective technical data, and demonstrate something feasible, tangible and directly applicable. With the correlation between the parameters, performed by the Fuzzy tool, it was possible to obtain a number that indicates the level of operational condition of the equipment from 0 (zero) to 10 (ten), and from this definition classify them in order of most able to perform the operation and the most priority in terms of maintenance. With several equipments under his responsibility, obtaining the perception of the quality of Reliability and Availability, joining the data of Maintenance by the Condition of an equipment and relating all this with support from Artificial Intelligence, a manager can obtain which are the equipments that must have more attention and investment at that exact moment. In this study it became clear which equipment should be prioritized in terms of maintenance and which is in better operational condition at a given moment. This can be a model of resource optimization desired by any company that operates in a sustainable and responsible way.

Adequacy of integrity models that meet the rules that respect the current legislation has become fundamental in the management of organizations as a strategic form, mainly in entities with public and non-profit purposes, in a non-governmental scope. Therefore, the objective is to implement a model for the application of the compliance program in a Third Sector institution. In this way, the present study can be considered in an exploratory, applied and qualitative way, in two aspects, bibliographic research and case study, the data collection was through a meeting and interview with the company's professionals, reporting on the importance of the theme. The results showed the main tools and compliance mechanism, proposing actions that can be used in practice with the purpose of providing a broad view of the functioning of the proposed model, with transparency and ethics, thus increasing the competitiveness of the business.

This work aims to propose a set of maintenance techniques defined from the application of the Reliability Centered Maintenance (RCM) methodology in the hydraulic system of a car dumper in a mining company. In this study, a survey of the equipment's operational data was carried out, both in the system and in the field, and after that, the inherent risks were determined as consequences of failures, classification of the entire system to obvious and hidden failures, as well as reliability analysis through risk measures and trust, in addition to the presentation of the equipment with its constructive form and operational context. As a result, a schematic model for application of maintenance tasks was proposed, covering the entire hydraulic system of these equipments and elaborating analysis of components and causes of failures. As a conclusion, the absence of effective maintenance plans to balance risk, cost and availability of a management and system for operational events data was verified. Additionally verified an average gain of 54% in relation to the number of failures, with the participation of actions in this work.

In the mining activity, the waste generated is the result of metallurgical processes to which mineral substances are subjected. Such industrial residues can be used as raw material for the manufacture of civil construction materials. Thus, in an attempt to make acidic slag produced by blast furnaces viable, scientific research increasingly seeks to minimize the environmental impact caused by the accumulation of these residues, through the development of appropriate applications for them. Therefore, it was adopted as the object of this study, the residue from the pig iron producing industry, the blast furnace slag. Establishing a form of another option of aggregates that enables the production of mortars with characteristics compatible with conventional ones, without the need for high consumption of natural aggregates. The chemical characterization of the used blast furnace slag residue was provided by a mining company belonging to the SINOBRAS group, located in the industrial district, Marabá - PA. The characterization of the residue was carried out using the technique of X-ray diffraction (XRD), X-ray fluorescence (FRX), laser particle size analysis, among other indices that characterize it as a fine aggregate for mortar. For the production of mortars, traces of different percentages of materials and EAF residue in the proportions of 400g of (portland cement, sand and slag) were made. After the curing process, it was possible to analyze the specimens through physical tests: absorption by immersion, porosity and compressive strength test. The results showed that, in general, the mortars showed a high increase in compressive strength in all specimens, especially for mixes 02 and 04, this increase was more accentuated, when compared to reference specimens, of this form, being analyzed and discussed by means of scanning electron microscopy.

This study aims to approach the implementation of a new layout of manufacturing process for high displacement motorcycles using the MASP methodology and Lean Manufacturing tools as a facilitator to adapt to the market oscillation. The research was carried out in a motorcycle industry located in the Free Trade Zone of Manaus, using the PDCA method (Plan, Do, Check, Action) for the feasibility after SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) in which the focus of actions of the project was defined. As a result, benefits were presented, such as: flexibility to increase production capacity due to the new layout arrangement and 67% reduction of Work In Process that made 25% of the total industrial area viable; versatility in the assembly process due to increased training of operators to produce all models; 5,5% reduction of the operator quantity keeping the same productive capacity; a reduction of at least 25% in the investment needed to implement new products, reaching up to 60% depending on the motorcycle in question, enabling the approval of the launch of four models in the last six months and avoiding an increase of 51.25% in value the asset chart; annual reduction of R$ 80,000.00 in costs with spare parts and preventive maintenance service; 15% reduction in electricity consumption; and a 5% decrease in line stoppage due to the limitation to change the production plan. With that, it provided greater brand competitiveness in the Brazilian market even when compared to other brands in the same segment that have already presented studies of process optimization focused on the Lean Production principle but limited to the manufacturing benefits.

The methodology applied to achieve the objective was developed from the bibliographic research, characterized through a field study, which went through the phases of direct observation of the facts in the transport process and the entire chain of the product storage quality process, with collection and analysis of the amount of hortifrúti. As for the results achieved, it was observed the need for the implementation of a refrigerated chamber for tomato storage, which maintains the quality of the final product, thus, the river company increases its profitability by 42% and the companies that transport the product reduce its loss by 46%, thus reducing its cost with transportation by 12% on each weekly trip of the hortifrúti. As a direct result of planning the use of the PDCA tool, also, stands out the increase for entrepreneurs farmers / hammerers of R $ 48,000.00 / monthly in sales to the market in the City of Manaus-AM, as a consequence of the improvement of the treatment of storage and transport of products. The PDCA tool contributed to the improvement of the logistics process and storage of the hortifrúti and resulted in the identification and diagnosis of the problem related to the lack of the refrigerated chamber, where in logistics transport and storage need urgent improvement, to reduce costs and the continuous improvement of the transport and storage of tomatoes.

Lightning strikes are of great importance for the electricity sector, being frequently responsible for disconnections of transmission lines, which can trigger a sequence of events that lead to the interconnected electrical system to collapse. The objective of this work is to propose a new methodology to correct the grounding resistances of the LT Oriximiná / Silves CD 550kV electric power transmission line in the Amazon aiming to reduce the occurrences of shutdown by disruptive return discharge, or backflashover, mitigating the damages caused to the system. electrical, considering the implementation cost factors, environmental technical feasibility, abruptness of the solution for other line structures, percentage of implementation reduction, it was concluded that the most adequate solution to implement a more robust grounding solution in the towers of the line transmission is the 03 solution tested on the 585 tower with a 66.98% reduction.

The unrestrained consumption of goods, coupled with population growth, caused a significant increase in the generation of solid waste in Brazil. The search for its correct disposal and sustainability has become an important aspect adopted not only by the private sector, but also by the public. Thus, this study sought to propose the application of Reverse Logistics in the final destination of computer equipment, after the process of disposing of assets at IFAM / CMDI. This research is of a qualitative nature and was used to recognize opinions about this theme, as it gives the respondent freedom to respond and give their own opinion. After analyzing the processes, it was noticed that, when the electronic materials are exchanged, the old ones are placed in a room, with the objective of analyzing which ones can be recovered by the computer team, and then a percentage of 20% a 25% is sent to Campi inland, and the rest is sent to a container and remains there until the entire process of disposing of goods is carried out. Thus, even with the evolution in the use of reverse logistics and consequently in the adaptation of Law No. 12,305 (PNRS), it is concluded that such growth is still not enough in view of the constant evolution of consumption and generation of waste by the Brazilian population.

After data obtained, it was concluded that the model proved to be very efficient, presenting a minimum difference from one supplier to the other, where the first place obtained a score of 2.06 more in relation to the selected room, seen as the longest distance in compared to the other classifieds, and it is important to continue the relationship with them in future acquisitions, one must also adopt the use of tools to recover those that did not show good results, in addition to the development of new suppliers.

This research presents a fuzzy inference model for evaluation of maturity in project management based on the MMGP model. Improving the accuracy of any assessment makes your result more assertive by directing initiatives correctly. You cannot manage what is not being used, and its measurement must be accurate so that the actions can be aligned with the real need, thus obtaining better results. This work seeks to improve the result of the analysis proposed by Darcy Prado [Prado 2000], where he conducts a questionnaire to score the level of maturity in project management of the organization. In view of the result of the questionnaire presented by the MMGP model, fuzzy inference is applied and the results are presented objectively, proving the best accuracy of the results. Both models, MMGP and MMGP+Fuzzy, were applied in one Company obtaining similar results, however, for the fuzzy model smoothing and accurateing the response, instead of the binary model proposed by the MMGP.

Institutions are subjected to the challenge of surviving in an increasingly competitive and demanding market, resulting from changes in the social, political, political and technological spheres, especially within the Covid-19 pandemic context. Quality appears, in this current scenario, as a timely and relevant theme. This research aimed to implement quality management methods in a line of confections of industrial uniforms to optimize processes. Aspiring to achieve the proposed objectives, a methodological choice was made through a quantitative and qualitative research, through a case study carried out in a company that manufactures uniforms at the Industrial Pole located in the city of Manaus-Amazonas. The survey involved eighteen employees and when asked about knowledge related to quality management, 22% demonstrated knowledge, to the detriment of 78%. About 83% of respondents consider the quality system to be efficient, while 17% disagree. Concerning the opening of the company to new ideas, 55% responded positively, while 45% do not feel at ease. Regarding the factors that cause bottlenecks in the process and rework, 50% reported that the finish does not meet the requirements, 33% reported a failure to insert the push button and 17% reported a failure in embroidery. The application of tools of quality helped to identify bottlenecks and analyze productivity. Solutions have been proposed to increase the efficiency and
efficiency of the examined industry, especially in terms of after-sales.

The search for efficient management is one of the main concerns in companies. Therefore, eliminating losses in maintenance can be done at the time when there is another way to perform a task. The research design was an exploratory case study. The objective was to map the type of critical loss in an automotive maintenance process in the operation and process functions, evaluating the factors that influence this loss in the flow of materials and services. The methodology was divided into three phases. The first phase was data collection, using research instruments and quality tools. A second phase was to carry out the mapping in the workplace, tasks and losses in the operation and in the process, to identify and prioritize the critical variables influencing the identified losses. The third phase was to evaluate and evaluate the critical variables using the Likert scale and Fuzzy logic. The result of the mapping was the identification of the critical loss, classified as "waiting". The problem related to this loss is that the vehicles stopped at the workshop due to the lack of parts with a simple delivery time of 3 days. The rates of delay for delivery obtained in the evaluation of the Likert scale is 48.8% and in Fuzzy Logic it is 50%, such results prevented that the difference between the two methods is low, thus confirming the reality of the process.

The need to improve the service to end customers and suppliers at a multinational in the Industrial Pole of Manaus, due to the low performance of its main KPI (key performance indicator) OTD (on time delivery) and which fluctuated by 56% delivery. Thus, the objective of this work is to raise this index to 92%. The methodology applied for this approach is centered on the philosophy of lean production and quality tools, and for that, a survey of the main problems that negatively impact the main KPI will be carried out in each area or sector of the company, therefore, this research suggests a method for the implementation of lean production based on a macro view of how a company works with a micro control of KPI's. The results point to a main common problem, namely, the communication between the sectors of the company, and several smaller ones that with the support of the board and the application of continuous improvement in the processes, it was possible to raise the KPI to 92%, and which, currently, the company has a delivery rate of 99%.

The target of this research is highlight the application of Lean Manufacturing tools in motorcycle assembly process.

Lean manufacturing is a production system focused to identify and maximize the added value of the products based on wastes reduction including value stream map, standardization and 5S.The project was developed starting from the literature research and case study. Direct observation in the shop floor collecting all data and analysis of them made part of this study. Regarding data, were collected the cycle time of all process, material flow and 5S status of the area. Significant achievements were reached during and in the end of this project. It was increased 15% of 5S score. Line stoppage was reduced by 52% with important actions like standardization and homologation of new method of material control. Significant increase of 37.5% in productivity and capacity raised the company to the next level. As indirect result is worth to mention a reduction of R$9,900/year in extra shipments due to material control improvement.

The Environmental Risk Prevention Program - PPRA is a mandatory instrument in companies that hire workers in the workplace and aims to preserve the health and life of the employees of a company, providing a healthy work environment. If it is not possible to eliminate the risk to the worker's health or life, a percentage must be paid added to his monthly salary, in addition to high costs with possible indemnities for work accidents. This dissertation presents the reality experienced in practice, through a case study in a concrete artifact industry, where data were collected through a checklist among its collaborators, detecting that before the implementation of PPRA (2001 to 2010), there were a large number of occupational accidents in the company surveyed and, subsequently, with the implementation of PPRA and a Work Safety sector, there was a great change and drastic reduction in occupational accidents, providing a healthy work environment where its employees they can develop their daily work more safely, preserving their life, health and that of their co-workers. The PPRA effectively applied in the company contributed directly to these benefits and improvements, which would not be possible if such Program remained only in its documentary form, without effective application.

The present work aims to investigate the application of the Richardson Extrapolation (ER) method as an alternative to reduce the simulation time of a specific CFD problem, which is related to a convective and diffusive problem. The geometry under study was built in the Blender software. The initial and boundary conditions were set using the BlenderFDS program, the calculation was done with a CFD code called Fire Dynamics Simulator (FDS), the results were extracted with smokeview software. In addition, Richardson extrapolation code was developed in the Fortran programming language. Flow field properties such as specific mass, pressure, temperature and velocity were calculated for three mesh sizes with and without the RE method. The extrapolated results show promise for maintaining accuracy at a lower computational cost.

With the advent of Artificial Intelligence, computers can make appropriate decisions reliably using Machine Learning techniques, such as an Artificial Neural Network.

This research aimed to evaluate the water quality treatment processes of SAAE and seven artesian wells in accordance with the legislation regarding potability, control and supervision of drinking water available for human consumption. Therefore, the water purification process was evaluated through laboratory analysis (microbiological and physical / chemical) and cluster analysis based on the averages of the results obtained, the correlations and dendograms from the analysis of 10 points in the network of distribution of the municipal water treatment system (SAAE) and 7 artesian wells, using samples collected every 30 days for seven months, with the first collection taking place in November 2018 and the last in May 2019. The classification of potability of these waters was based on the parameters of Ordinance No. 2914 of December 12, 2011, from the Ministry of Health which by Consolidation was replaced by Ordinance PRC 005/2017 from the same office. The results obtained from the samples collected from the artesian wells allow us to state that the waters of the artesian wells analyzed, for the most part, are not suitable for human consumption, since they are contaminated by E. Colli(wells 4, 5 e 7 – being)and Total Coliforms (all wells show ingana verage of 440 U.F.C.), also have high levels of conductivity(specifically in the wells 4 and 6) when compared to samples from the SAAE water treatment station. In the water samples from the SAAE treatment plant, pH values were found that are in disagreement with current legislation (all have values less than 7), requiring a correction in the process to adjust the values found. In general, the Municipality of Cacoal meets the parameters required by current legislation regarding potability, however there is still insufficient continuous monitoring of water from artesian wells that is available to the population, without any type of control, either of quality or use, due to the lack of inspection, requiring continuous monitoring in order to adapt the use and the correct destination of consumption of these waters. In this sense, it is necessary to implement public policies by the local government, through inspection, using local health supervision, seeking to make the population aware of the need to adapt and seek solutions to standardize the proper use of wells, carrying out periodically laboratory analyzes aimed at raising the population's awareness of possible dangers to public health, as well as the need to use the local sanitation service (SAAE).

Industrial water is a driving force for any manufacturing process, which is a scarce and finite natural resource. For its use to be rational many measures in the manufacturing environment must be taken in order to preserve this asset. In industry, condensation water from compressors is channeled into the stormwater gallery. In turn, in the cooling towers, the basin water evaporates and its replacement with artesian well water is necessary. In both processes water is wasted. In order to elucidate these situations, the procedures can be developed by channeling the compressor purge drains into a cistern and pumping water into the cooling tower basin. The methodology of the present research is configured as experimental, since compressors were used for the recovery of previously unserviceable waters. Thus, the water that was once discarded in the compressors will be reused in towers that do not require such quality. This reuse may solve the problem of continuous replacement in order to maintain the basin water level required by the tower. The application of this feature will reduce the costs of chemicals in cooling water by approximately 59%, because will not be necessary treating the aggressiveness of the salts present, as they will be in very small quantities. Hence the reuse of this asset will favor not only the preservation of a natural resource, but also the reduction of chemical consumption in the tower, as well as the reduction of maintenance and cleaning costs in these equipments.

Public sector organizations are usually associated with very fast, bureaucratic processes that generate late results. As a result, the performance requirements of public sector agencies have grown. Many critical problems occur in industrial processes, and companies often do not adopt structured procedures to solve them. Thus, this work aims to apply the Define, Measure, Analyze, Improve, Control (DMAIC) methodology. In this context, this study aims to analyze and propose improvements in the process that performs the maintenance of ships, using the DMAIC and the quality tools, as well as identify the barriers to application and improvements through this methodology. The research strategy adopted was the case study applied to the ship maintenance process. Based on the DMAIC, process improvements have been proposed so that planning actions can be taken to meet the demand for these services. Through the application of Value Stream Mapping (MFV), Ishikawa, SWOT and others can alleviate the lack of standardization of procedures, lack of systemic view of process flow on the part of managers, deficiency in server capacity, lack of focus. on the end customer.

The large number of ceramic industries in the country has increased concern about the health of workers who work in this area of activity. The nature of the activity requires the State to be concerned about the common or working environment, which means that it ensures the safety of workers in their work performance. Regulated norm 15 brings as possibilities of payment of additional unhealthiness for cases in which the worker performs his activities, endangering his health. In it are exposed the cases of unhealthiness without ruling out other possibilities as long as identified by the professional technician qualified by professional qualified to perform it. Excessive heat, noise, dust, debris and lack of protective equipment are some of the factors that endanger the health and therefore the life of the worker. These risk factors are easily applicable in the red ceramic industry. The action plan is presented as an intervention measure to correct the possible errors found in the ceramics industry that can cause damage to workers' health and point out as positive consequences that an adjustment causes in the work environment. Educate both the employer and the employee to whom he or she invests most in occupational accidents and the worker obeys the imposed rules. This imposes on the State the obligation to inspect and fine companies that violate the legal norm. The lack of PPRA and PCSMO makes it difficult to identify risk areas and, consequently, to define actions to minimize or eliminate the risks of delays and work accidents. With the action plan as an intervention or risk measure, they can be reduced and work accidents avoided.

It is known that communication, despite the technological advances still presents numerous bottlenecks that can compromise the safety of the air traffic acted by pilot and control; and pilot and other aircraft. However, this process is more complex because it involves aspects of communication related to language, language understanding, ambiguity, uncertain reference, implicit inference, homophony, intonation, repetition (or comparison), and so on. The present dissertation aims to analyze the alternatives for detecting failures in the communication process and the impacts on flight safety by air traffic control. Thus, it should be emphasized that the objective of this work is to analyze the communication process and its failures in air traffic control and to propose devices to detect these faults in a preventive way in order to reduce the impacts on flight safety. Therefore, it is extremely important to propose a communication failure detection, reducing possible risks that can lead to air accidents. Despite this technology applied in the communication system between ground control stations, the communication model used between controllers and pilots, is still a segment that needs a lot of attention and new ways of improving the communicative process, which still has outdated characteristics and which generates negative influence of the several elements described in the communication models to be studied. Its methodology has a bibliographic nature with an experimental proposal.

The large amount of organic solid waste from the fishing industry is a serious socio-environmental problem. The treatment of organic solid wastes, such as the residues of the fish slaughterhouses, has a great reutilization potential, being able to generate by-products that attend both environmental and economic aspects. The aim was to study and propose ways to treat the fish processing residues from Frigopeixe Frigorífico, aiming to provide a sustainable destination for that material in order to achieve the goal of decrease to zero the disposal of those residues in the sanitary landfill of the city of Tefé, without burden the company. In particular, three techniques of reuse of fish waste were studied: composting, silage and fish meal. The study took into account the company production per harvest of 969 tons, on average, and waste generated quantity of 171 tons, on average, the extent of the technique in the reuse of the waste, the cost of implantation, period of storage, maintenance and return on investment, as well as the socio-environmental gain with that implementation. Each of the techniques studied presented great potentials of reuse of the residues, but the production of fish meal proved to be very expensive in its installation and maintenance, becoming, initially, not feasible. The other two techniques have a more adequate profile with the production and investment dimensions of the company, being able to be made a joint deployment, being a technique complementary to the other in the reuse of waste, composting and silage.

The study was exploratory and descriptive, through a case study in a refrigerator of this city, as well as bibliographic and documentary research, with information gathering from the Mamirauá Sustainable Development Institute Database, and the Fishing Landing Bulletin. of this Institute. The data analysis was quantitative and qualitative, with the presentation and description of the records through tables and graphs, which show the variation of fishing landing, river levels, as well as the analysis of the process of catching fish and fish. factors that influence the fishing landing. It is believed that the data from this study may favor the development of strategies and alternatives to optimize the fish logistics in the municipality of Tefé, thus providing an increase in the company's profitability and also a greater gain with fishermen.

The increase in the efficiency of industrial processes has been necessary in the present day, due to the high market competitiveness. In this context, techniques that seek to increase the performance efficiency of industrial plant control systems, minimizing costs and maximizing product quality, such as the use of Kalman Filter in process variables that feed control systems, has significant relevance. Kalman filter is a parameter estimation technique that allows, for linear systems, the reduction of noise and uncertainties that are subject to process variables. Its wide use is mainly due to the fact that the variables (information) that are obtained through the process, through physical instruments and measurement routines, have finite precision and are naturally corrupted by errors (random or coarse). These variables, when introduced into the control system, without the use of the Kalman Filter, carry all noise signals, reducing the performance of the control system. The aim of this work is to present the results of the Kalman Filter implementation in the industrial process, a propane generator column, controlled through a Predictive Controller, based on real data, in order to improve control performance and energy efficiency of this process. Simulation studies are performed on the MATLAB / SIMULINK platform.

For the Amazonian population, cassava flour is part of the diet, being produced in the flour houses in an artisanal and semi-mechanized way. In this production is generated two types of waste, the solids and liquids that are passive environmental. In view of this reality, this study focuses on the sustainable use of residual liquid called manipueira, as a source of nutrients for agriculture, to the molds already recommended by EMBRAPA in several regions of Brazil. The locus of the study is the community of Cucurunã municipality of Santarém, state of Pará. The methodology used the spatial survey of flour houses, the monitoring of flour production, the collection of the manipueira and its physicochemical characterization using analysis techniques of BOD, COD, pH, temperature, sedimentable solids, cyanide contents and research data of technical / scientific work for later analysis of the potential of manipueira as nutrient. Thirteen flour houses were visited in the community and it was observed that all of them use white and yellow cassava as raw material. Two that use the artisanal process and make it in a joint effort were chosen for the research. The physico-chemical characterization of the effluent presented the following results: BOD, 7,874.00 mg / L; COD, 67,711.21 mg / L; pH, 4.3; temperature of 25.16oC, sedimentation solids and cyanide content, 22.31 mg / L. The theoretical survey showed that the flour industry residue has great potential for use as fertilizer in agroindustry, using simple already consolidated techniques of application involving the community.

This study aimed to analyze the factors related to noise that may cause harm to the team of health professionals working at the Material and Sterilization Center of the Baixo Amazonas Regional Hospital, in Santarém, Pará, Brazil. This is a transversal, descriptive, exploratory, field study, with a quantitative approach, carried out in an establishment of high complexity. The data were collected in the months of June and July of 2018. The measurements were performed in the morning and afternoon, based on a time of greater activity and another with low activity in the CME rooms. In view of the results, high NPS were found at the site, much higher than legally allowed. It was also observed that the machines that produce the most noise are: the autoclave in use, the ultrasonic washer of materials and the compressed air pump. It is concluded that the fast pace of work, physical and mental requirements, information flow, poorly ventilated area, autoclave heat, intermittent noises and the presence of chemical, biological, ergonomic, physical and accident risks are constant inside the material center and sterilization. All these factors are sufficient to cause physiological and psychological changes in the professionals who work there.

The expansion of Brazilian agricultural frontiers has provoked a strong need for the country's logistical adequacy. The search for optimization and efficiency of operations has become of great importance for reducing the cost of logistics freight and the competitiveness of Brazilian producers in the international market. The growth of agricultural exports, port operational inefficiency and stricter environmental laws have created a new problem for Ports: an increase in grain waste generated during operations. Before being seen with low relevance, the new scenario has required a proactive attitude of the managers, seeking to optimize the generation of grain residues through operational efficiency, better waste management, as well as search for new alternatives for environmentally correct destination of the byproduct. Thus, a case study was carried out at the São Luís Port Terminal, analysis of the generation history, as well as the practice of final destination of this waste through landfill, together with the operational costs of cleaning, transportation and disposal of the waste. After that, it was identified that the main causes of waste generation in the Port are operational failures, not standardization of the industrial cleaning activity and bad design of the civil warehouse projects. The PDCA model was used for analysis and troubleshooting. As a result, 60% of the grain's waste generation in the Port was reduced, a complementary solution was developed for the final destination of the waste, through sale of the by-product, for blending and composting, and reduction of cleaning, transportation and disposal costs.

This work used the methods of absorption costing and variable costing, as a proposal to improve the allocation of costs of the production process in a Plastic Injection Industry. To reach the proposed objectives, a case study was carried out, through a quantitative and qualitative research. At the end of this research, it was possible to identify the unit cost of the cover and the cabinet, respectively, of R $ 0.26 and R $ 0.81, absorption cost method; R $ 0.14 and R $ 0.45, using the variable cost method. In the statement of income, a positive result was obtained, which represents 1.06% of the net profit, but the office presents the high unit cost, mainly in the acquisition of the raw material, compromising the company'sprofit, and it is up to the company to decide between discourage this type of sale or look for suppliers with lower raw material prices. It was verified that the variable method is closer to the reality of the company in decision making, because it monitors the costs and changes that may occur if there is a change in production volume. As a final result, the present study showed that the implementation of absorption and variable costing methods are easy to apply and can be deployed in any company.

Industrial activity is of great importance for the economic growth of a country, contributing to the generation of domestic wealth. The objective of this work was to address the use of Natural Gas (NG) as an energy source, and its correspondence with the economy, establishing a prediction model of the national natural gas supply based on variables of an economic nature. For this, we selected the independent variables of an economic nature with the variable object of this study. The period considered for the analysis was from 2010 to 2015. A normality test was performed, the static significance tests, ANOVA, independence test of the variables with 95% confidence levels for p-value of the test were performed. Hypotheses for the model variables. Seeking to show the rejection or acceptance of the hypotheses for the correlation between the economic variables or related to the national GN level offer. The hypothesis test carried out accepted the hypothesis of the influence of the variable GDP on the National Natural Gas Supply, for the period considered in the multivariate analysis. This study found that Natural Gas presents itself as a substitute for the common diesel oil, due to its inverse cross-elasticity. It was also evidenced that the Natural Gas is a complementary good in relation to Natural Gas due to its positive cross-elasticity in relation to the latter.

This work implemented a Fuzzy System of Evaluation of Government Programs, evaluation of the mid-term type, presenting improvements in relation to the current system, called Preventive Control System - Monitoring and Evaluation of Programs (SICONP-MAP), in the treatment of points of singularity and cloudiness, with potential possibility of incompleteness treatment. The modeling was implemented in the JuzzyOnline and RProject platforms, where both evaluated the "Security for Peace" Program and presented 99.99% similarity, 0.101914 for the maximum difference of the residual values, 0.003688 for the median, and 0.035 for the standard deviation. These metrics showed that there were no differences between the implementations with a level of significance lower than 0.1%, where it is inferred that the modeling is robust. Robustness was compared with SICONP-MAP, where the Fuzzy System presented an accuracy of 88.88%, corresponding to 24 of 27 actions evaluated according to reality, against 44.44% of SICONP's accuracy associated to 12 actions with assessments adhering to reality. Considering that the Fuzzy System points out the distribution of stratified actions in the field of evaluation, ie the performance characteristic of the Program based on actions; it was observed the distribution of the expenditure realized in the field of evaluation, and then it was verified to what extent the first distribution explains the distribution of the expense. The sequences presented 94.82% similarity, 0.029291 for the maximum difference of the residual values, 0.008312 for the median, and 0.007549 of standard deviation, confirming a significance lower than 0.1%. Despite the high correlation, the metric of the expense, which points for the quality of the expenditure, evidenced the risk of classifying 43.64% of the expenditure as high performance whose actions were included as suspected of "Planning Failure". The implementation can be extended to all spheres of government, applying directly to any Program that does not present incompleteness, otherwise it is necessary to pre-treat the data

The use of residues in clay-based composites has been used for the production of ceramic materials. It has recently been extensively researched for presenting significant results in its physical and chemical properties. The purpose of this work is to analyze the efficiency of the incorporation of 10%, 20%, 30% by weight of blast furnace slag originating from steel mills in the State of Pará, in the clayey clay composed of strong clay and weak clay yielded by Menegalli ceramics, located in the municipality of São Miguel do Guamá, to produce sealing blocks. Comminution occurred for the purpose of reducing particle size, and then a screen with a mesh aperture of 325 mesh was used. After this step, residuals and raw materials were submitted to FRX, EDS, XRD, TG / DTG, particle size distribution, MO and MEV, with determination of the limits of plasticity and liquidity, showing beneficial results in the compositions AFOAFR and AFOAFR10EAF, which are present in the optimum extrusion area, showing great importance in the ceramic industry for the production of blocks. The test bodies were prepared by uniaxial pressing of 20 MPa, then the muffle furnace stage was carried out at temperatures of 750 ° C, 850 ° C, 950 ° C. Physical and mechanical properties such as: MEA, AA, and flexural strength were obtained, obtaining efficient results for the industry. The microstructures of the burned ceramics were evaluated by MO, MEV and XRD. The results showed that the blast furnace slag is a residue composed of iron oxides, which contributes to the reddish color in the ceramic pieces.

Railway rails are purchased in 24-meter pieces and welded to larger bars, up to 360 meters, before being installed on track. These welds, when in service, suffer deformations that can lead to the fracture of the welded joint. This work aims to present a methodology to measure residual stresses in the flash butt welded zone on rails. The rails used were hardness level greater than 370 HB, carbon content approximately 0.79%. The rails were welded through flash butt process, carried out by the stationary equipment Schlatter GAAS 80. The technologies currently applied for the measurement of residual stress demands destructive or semi-destructive tests. This dissertation pursues a non-destructive technology capable of being applied in the field for the measurement of residual stresses on installed rails. The technology used to measure residual stress was x-ray diffraction, the equipment used to measure the residual stresses was the X-Stress 3000 analyzer. The results showed residual stresses in the welded zone, where specific zones of tensile stresses are presented near the center, and values of 391 MPa close to the center of the weld joint, and compressive stress was noted as it moved away from the weld center in values close to -166 MPa. There was compatibility with the available bibliography on the subject and, therefore, the technology shows great potential to be applied on railway rails.

Access to a health service is guaranteed by law to every society. However, with the help of resources available for this area, better access to medicines, research studies and market competition, the need to find alternatives that allow cost rationalization without compromising therapy has become essential for the maintenance of the Cheers. In this sense, this work had as objective the importance of pharmacoeconomics in the oncology sector of a public hospital in the Brazilian Amazon. Experiencing the exponential growth of public health expenditures is an economic feasibility assessment strategy to optimize resource scarcity more efficiently. Pharmacoeconomics is characterized by the application of drugs in the use of medicines, minimizing financial expenses without compromising treatment. The dispensing of the minded onedicalors in the scientific software is leveduring as function aegalias. The global debate on the feasibility of social conditioning is to take into account a cost-effectiveness ratio that relates costs to health. According to the National Cancer Institute, it is estimated, for Brazil, the biennium 2018-2019, the occurrence of 600 million new cases of cancer, for each year. The mismatch between available resources and advances in cancer therapy requires benefit projects in cost-benefit, cost-use, and cost minimization processes. In view of this scenario, we have drawn towards the macroscopic challenge of pharmacoeconomics in the antineoplastic therapy sector of a public hospital in the Brazilian Amazon, entitled UNACON (High Complexity in Oncology Unit). 2011 that provides oncological care to 19 municipalities in the West Paraense and Paralelo Recorrente de Oncológicos No Proportional Partitioning of Institutional Resources.

High energy consumption (EE) has driven EE generation in developed countries. In Brazil, 18.2% of the energy generated is thermoelectric. Generation of energy by Motor Generator (MG) is strategic, however, with a high cost of implantation and maintenance. Because of a high cost, maintenance based on the function parameters of the MG, has been increasingly important in the prevention of errors of these engines. Thus, the present work has the objective of developing a model of operation frequency data analysis based on the operation of an internal combustion engine (MCI) cooling system. The fuzzy inference model adopted for the fault prediction system is not based on computational models of combustion pressure and water pressure. The evidences were presented according to the needs of the performance monitoring system of the power generator system, with a greater efficiency and safety for the protection systems.

Lean warehousing is a relatively recent topic in organizations regarding the use of lean production tools since its focus has always been on the manufacturing environment. However, with the widespread dissemination of the lean culture in all sectors of Western companies, the subject became valid given the lean tools’ high applicability and simplicity of understanding. On this matter, the objective of the present work is to apply the lean tools and start a mentality and culture development process in a heaty machinery parts distribution center. The methodology used was the application of lean tools in the warehouse environment through the PDCA cycle (plan, do, check, act), proposing process’ stabilization through 5S, load leveling through heijunka, waste (muda) identification and reduction through value stream mapping, reduction of employee movement using standardized worksheets, and creation of a culture to stop to solve problems focusing on root cause analysis. All these topics were supported by employee training, aiming their immersion in the lean culture. After the lean tools application, one of the principal results was regarding the warehouse lean maturity, which increased from 2,25 to 3,75, in a 0 to 5 scale.

Industrial AGVs have a wide range of applications in the processes they are part of, bringing benefits from flexibility to changes in these processes to improving employee safety. Allied to these robots, the PID controllers appear as one of the most used methods for the control of these vehicles. In recent years, heuristic optimization methods have gained space in the industrial area, and are strongly associated with the control strategies used. This work presents a PID control proposal for a unicycle type AGV, with its parameters optimized by the gray wolf algorithm (GWO), a heuristic optimization technique based on the hunting behavior of the species that gives its name to the technique. The performance of the PID controller is compared to the kinematic controller used by the reference work. For each trajectory tested, fifty simulations are performed for the determination of standard error and standard deviation, with GWO and robot trajectory evaluated by graphs. The effects of the number of iterations and search agents are observed in relation to the performance of the algorithm. In the end, the advantages and disadvantages of the project are evaluated and suggestions for continuation are given.

The largest application of recycled PET is intended for bottle2bottle bottles. This technology has been used successfully in the countries of Europe and Central America since 1991, however in Brazil it is little explored, causing the recycling indicators to remain far below the expectation of the National Solid Waste Policy. The reasons for this work are related to the reason for the delay in the use of this technology in Brazil, so the general objective is to present the influence of the use of PET-V and PET-PCR on the quality parameters of the production of packaging for beverages and specifically to compare the residual migration values of chemicals and the quality characteristics of the beverage cartons manufactured from the PET-V and PET-PCR blends. Proportion of 80/20 in large-scale production in the two-stage process in 41 g preforms and 2000 ml bottles. The migration results, AA, burst test, free fall and stress cracking remained similar to PET-V. The intrinsic viscosity fell sharply, leading to a deviation in material distribution, volumetric capacity and dimensional expansion under temperature (EDT) of the bottle. There was detection of variation in size, shape and color of PET-PCR pellets and appearance of high black speck index less than 5 mm.

Much is discussed about the use of statistics for the health area and much is still discussed, related to the epidemiological profiles of hospital morbidity and mortality in several regions of Brazil and in the world. The statistics of morbidity and mortality constitute an important subsidy for the knowledge of the epidemiological profile of a population, elaboration of health indicators and consequent planning of actions of the sector. Based on these principles, the objective of this study is to conduct a study of Hypertension and Diabetes in the epidemiological indicators of hospital morbidity and mortality in the SUS network, during the period from 2011 to 2016, in the Municipality of Santarém in the state of Pará, according to International Statistical Classification of Diseases and Related Health Problems (ICD 10). A retrospective study was conducted with a quantitative study using systematic records to obtain data in a specific period, place and sample. The purpose of this study was to characterize the hospital epidemiological profile of morbidity and mortality in the municipality. When analyzing the records, it is evident that the number of deaths occurred, counted according to the place of residence of the deceased, is more representative in the hospital records, for all age groups as well as for all sexes. The correlation between both diseases allowed us to identify that although hypertension affects men and women and that their prevalence increases with age, they are also present among adolescents and children and that when associated with diabetes, it increases the risk of developing cardiovascular diseases. Finally, what could be verified with the development of this work is that the strategic planning of the municipality should compose incentive proposals to improve the health indicators of the population. In other words, in addition to being able to develop innovative solutions such as health care programs, they can organize, monitor, evaluate and correct in a simple and integrated way the various processes that constitute the health of the municipality.

The use of electric energy for ambient air conditioning is one of the great challenges in the search for alternatives for the supply of energy in large consumption centers. The various regions of the world, such as the equatorial ones, are among those that demand a great amount of electrical energy to feed a state of greater importance. The work was a model of air conditioning suprised by photovoltaic generation, with the unit of conditioning of photovoltaic air (UCAFV). The proposed system was investigated using data of ambient temperature and irradiance for two days of the city of Belém, located in the state of Pará - Brazil, a locality with climatic characteristics very similar to numerous regions near the equator. For this study, two days were analyzed, one sunny day and the other cloudy, where a computational tool was elaborated using the EES - Engineering Equation Solver software to simulate the behavior of the system, considering the natural adjustment of the cooling capacity according to with the rate of energy production by the Photovoltaic Generator (GFV), that is, without any type of control system to regulate the refrigeration capacity and the internal temperature of the conditioned environment. For this study, GFVs with nominal power (𝑃𝐹𝑉0) of 700 Wp, 1000 Wp and 1400 Wp were simulated for direct feeding of the Air Conditioning System (ACS), considering the minimum and maximum cooling capacity limits of the system commercial used. The cooling capacity, the coefficient of performance, the condensation capacity and the internal temperature of the environment to be conditioned, according to the variation of the cooling capacity, were calculated. This, in turn, is a function of the power produced by the GFV, delivered to drive the SCA. The thermal load corresponding to the set consisting of walls, windows, people, lighting, equipment, etc., was determined using Hourly Analysis Program (HAP, Version 4.9) software. As a case study, we used the library environment of the Group of Studies and Development of Energy Alternatives of the Federal University of Pará (GEDAE). For the UCAFV, the maximum cooling capacity obtained was 5.78 kW, corresponding to the 1.28 kW power generated by the GFV with nominal power of 1400 WP for the sunny day, in the interval between 11:00 and 12:00 h . For the sunny day the average temperatures found for the simulated environment with (𝑃𝐹𝑉0) equal to 700 WP, 1000 WP and 1400 WP were 22.6 ° C, 21.7 ° C and 20.4 ° C respectively and for the day cloudy at 26 ° C, 25.2 ° C and 24.3 ° C, respectively. According to the data obtained in the simulation, it was concluded that the UCAFV has the potential to be used in the air conditioning of domestic environments and commercial offices in the city of Belém, as well as in other locations with an equatorial climate. In addition, the tool and the methodology developed can help in the accomplishment of future studies within this theme.

The highest temperature under which a CPU can operate without interruption is 90 ° C. When the TDP of processors is very high, generally heat sinks provided for removal of heat prove to be inadequate when the CPU usage is 100%. The objective of this work is to explore the thermal transfer using the DTML method in a computer cooling liquid application with Intel® Core ™ i5-3330 to 3.0GHz quad-core processor. Both the coolant fluid and the liquid cooling kit purchased for the experiment belong to the manufacturer Thermaltake, the reference company in the following. An experimental bench to measure the flow, the inlet and outlet temperature of the water block and the acquisition of the data were assembled. Under maximum working load condition, the CPU was subjected to maximum CPU temperatures of 75 ° C with standard fan (heat sink + cooler) and 53 ° C with the watercooler kit, at an average flow rate of 2825 ml/min. The maximum operating efficiency achieved out of 0,439W of energy savings compared to the traditional heatsink.

PID controllers are increasingly present in various industrial processes. Even so, as popular as control systems are, there are still some issues that merit studies. This is mainly due to the fact that most of the control networks in the industries are faulty in the tuning. The current paper presents the development of a methodology for modeling and analysis of industrial plant control systems based on real data, to improve efficiency and optimize the parameters of the plant. By showing the results of tuning the parameters of a PID controller from the identification of the dynamic model of the flow control of the LPG loading pump of a load terminal of propane vessels, this plant transfer function has been obtained by the method of the process reaction curve through a step disturbance in the manipulated variable (pump rotation). Simulation studies are performed on the MATLAB/SIMULINK platform to ensure the performance of the controller. The controller tuning is made by MATLAB/PID Tuner. The result of the simulation provides an appropriate tuning for the PID controller, managing to keep the variable controlled at predetermined values.

High-voltage disk isolators are equipment used in power transmission or distribution networks, and are useful for supporting the conductive cables and at the same time insulate them electrically. They consist of a metal bell, a metal pin and a glass or porcelain disk. The joint action of atmospheric pollution, humidity and intense electric field on the surface of these insulators provide the incidence of electric discharges in the central region of the pins which catalyze the process of corrosion and rupture thereof, resulting in catastrophic failures in the electrical system. In this sense, this work developed an electrostatic protection device, called "Faraday Cage for Disk Isolator Pins", aiming to shield the intermediate region of the pins against the effects of the external electric field. In addition, it proposed the application of super-hydrophobic coating under the insulator glass disk in order to facilitate the removal of the atmospheric contaminants that induce the emergence of the voltaic arcs that are directed to the surface of the pins. Through a van der Graaf generator, experimental tests of electric shocks were carried out under a pin protected by the first prototype of the device. And with the aid of simulation software, based on the Finite Element Method, some computational simulations of the electric field distribution were carried out on 2D models of chains of insulators added by the device. The tests verified that the device was able to avoid the incidence of electric discharges, of the order of 20 to 90 kV, in the region of the pin of greater occurrence of corrosion. The results of the simulations, in turn, clearly showed that the device can cancel out the intense electric field on the intermediate surface of the pins, whose intensity reached 52 kV / m in the vicinity of the device that was protecting the pin closer to the terminal of 69 kV considered in the graphical models developed for the simulations. Finally, it was found that the application of super-hydrophobic coating on the glass surface of an insulator was able to considerably reduce the accumulation of particulates under it, which corresponds to the contact angle of 155.55 ° which was measured between a surface flat coated and a drop of water.

The globalization and consolidation of multinational companies result in increased competition between factories within the same group. A factory must always strive to reach the level of excellence, meeting the standards of world-class manufacturing, optimizing resources and reducing its operational cost. In this context, the Lean Manufacturing arises, which, by systematically attacking the wastes within the productive processes, seeks to maximize operational efficiency, and for this reason, has been shown as a very successful option in the globalized competition. However, the adoption of the Lean Manufacturing in the companies settled in the Manaus Industrial Pole is not following the speed that the market demands. This work is based on the premise that the Lean Manufacturing system when applied to a motorcycle manufacturing company installed in Manaus Industrial Pole in a structured manner, will lead the company to a productivity gain and consequent reduction of operating costs. In this way, the general objective of this work is to implement Lean Manufacturing in a motorcycle manufacturer of high displacement motorcycles installed in the Manaus Free Trade Zone. The case study methodology was used, guided by the PDCA tool. A multidisciplinary group was organized, and the lean maturity level was determined by applying the SAE J4000 standard. The Kaizen program was created, followed by the implementation of visual management, Line Balancing and Quick Tool Exchange (SMED). The research is finished with a review of the results achieved, as well as with the presentation of the author's considerations regarding the relevant peculiarities related to the process of implementation of the Lean Manufacturing. concluded that the main result was achieved, increasing the Lean maturity of the production process to M = 0.74, according to the J4000 Standard, which means, the Lean Manufacturing is implemented and presents effective results.

The controller corrected the real-time regime error, the system is always positioned at the maximum irradiance angle that can be observed with the results presented from the analysis of data collected from the system operating in mode: manual and automated tracking, another factor that demonstrates the efficiency of the concentrator is the concentration rate, which is the ratio between the area of the gutter opening, that is, area receiving the direct radiation and absorption area, prototype showed a rate in the value of 14, this is a parameter which affects inversely proportional to the thermal efficiency of the concentrator, ie the energy balance, but this result is within the limits of tracking on a single axis. The maximum energy efficiency was 127.81 ºC for manual tracing and 131.70 ºC for automated tracing. Thus, the implementation of the automated tracking method on a single axis, based on the analysis of the results, proves the contribution of the work compared to manual tracking methods.

The technologies setted were the Fast Ethernet and Gigabit Ethernet. With the mounted system, was achieved the executed services quality, the compatibility with the current and future systems, besides the systems interoperability.

The maximum chemical productivity in the extraction of alumina (gibsita) has been a differential factor of competitiveness in a plant that uses the Bayer process. The objective of this paper is to reproduce, in the laboratory, how the operational control variables used in the Alunorte refinery, they influences the solubility of gibsite in caustic liquor. This study uses statistical methods and experimental modeling, to obtain the effects on the yield of this extraction, due to variations in digestion temperature, caustic concentration of the attack liquor, residence time (reaction) in the digesters and calcium oxide content. This study uses as result of extraction productivity, the ratio between the content of Alumina dissolved in Caustic Liquor (A / C ratio) and the concentration of silica in the green liquor (high alumina extraction product). Because considers that the reactive silica is a contaminant, it needs to be controlled and discarded along with the other oxides present in the bauxite. By means of the laboratory results and statistical analysis it was concluded that they had a significant impact, both in the A / C ratio and in the dissolved silica, the Caustic Concentration, Temperature and residence time (reaction) in the digestion. The behavior of these variables were modeled in proposed equations for A / C ratio and silica content, with good predictability between the actual value obtained in the plant and the value calculated by these equations.

This paper aims to propose a real estate appraisal model that incorporates the imprecisions and subjectivities inherent to the variables that make up the real estate market, to be used by professionals working in the area. The developed model uses Fuzzy logic to define the subjective characteristics of real estate, in the form of linguistic variables, assigning to each of them pertinence functions, reflecting the thinking of human specialists in real estate appraisals. The research also addresses the use of rules extraction techniques for the classification of relevant attributes, called the Decision Tree, to reduce the rules originally established in the proposed Fuzzy model, without losing focus on the logic of the process. This objective reduction makes feasible the practical use of the proposed model. To validate, a comparative analysis of the use of the Fuzzy model was performed, to which two groups were submitted and the generated values were compared with real market data, obtaining the Standard Deviations in the range of R $ 600.00 and the percentages of deviations of the values of the values generated and collected in the field, in relation to the Standard Deviation in the range of 15% and 17%, for both groups, showing a uniformity in the calculations performed by the proposed Fuzzy model.

The assembly line balancing problem has been an object of study for a long time but is still something of a high level of interest on the part of the industry, especially for the ones that produce goods for mass consumption, where manufacturing costs represent a significant portion of the total cost of the product.

Pumping of fuels represents an essential activity in refineries and distribution terminals, this activity is responsible for the most part of energy consumption in those facilities. This thesis had as main objective the development of solutions to optimize the discharge time of tank wagons in a fuel distribution terminal with predetermined operating time lapse. There were conditions determined by the management of the terminal, aiming the reuse of available equipments which proved ineffective, being discarded later. The solution to be implemented contemplated the sizing of centrifugal pumps and pipes according energy waste of each system. A spreadsheet was done to determine the performance curves of each system and centrifugal pumps to be installed, getting the operating points given by the system / equipment interaction. The spreadsheet was developed based in the Darcy-Weisbach formula for loss of energy during flow in pipes, analyzing each systems section and given the required manometric height for the pump operating in different flow rates. In the end it was verified that the correct understanding of the fluids properties was essential to properly size the pipes and pumps, solving the company's problem raising the volume discharged in a acceptable time lapse.

The objective of this work was to identify the consequences and influences caused by the dissatisfaction of the assemblers consuming manufactured foods by the outsourced company, through the mapping of indicators that affect directly and indirectly the process of functional performance of these workers. The scientific method was developed through an explanatory research about its objectives, since it was necessary to identify factors that could influence any disturbance or anomalies of the index of satisfaction of the food served, being therefore necessary the accomplishment of two analyzes, being: one in the own industrial kitchen and another in the consuming population of these dishes, through the consumers. To make better use of the scientific method, it was necessary to carry out an investigative questionnaire for most of the sample of people involved in the process, and consequently there was also the need to carry out a complementary interview with some people, in order to analyze and confront peculiar or identified in the process. The conclusion is that it is and genuine to state that "if the quality of food served to the assemblers is classified as weak, technically there will be an opening for the possible formation of dissatisfaction bubbles that could trigger in a decline of industrial labor performance, either autonomously or associated with other types of dissatisfaction."

In this work, a study on the viability of the white ceramic waste generated in the city of Manaus for the production of mortars was proposed. X-ray fluorescence and diffraction analyzes showed that the residue contained 66.69% of silicon oxide, 15.58% of aluminum oxide, 8.18% of iron oxide and 1.18% of oxide of sodium. According to ABNT-NBR 12653, 1992, the residue has the characteristic of a pozzolanic material, which can produce a more efficient arrangement in the aggregate-cement paste interface. In this way, for the production of the mortars, five mixtures (TR traces) composed of white ceramic residue, sand and cement TR1 (50% RCB-43% sand-7% cement), TR2 (40% RCB- sand-7% cement). TR3 (30% RCB-63% Sand-7% Cement), TR4 (20% RCB-73% Sand-7% Cement) and TR5 (10% RCB-63% Sand-7% Cement). The mortar was formed in cylindrical specimens, which were cured for 28 days. After the curing period the CPs were submitted to the physical-chemical analysis, which were: apparent porosity, apparent water absorption, apparent specific mass, compressive strength, fluorescence and X-ray diffraction analysis and scanning electron microscopy. Through the analyzes, and comparing the resistance results obtained for the mortars at 28 days of cure with ABNT NBR 13279 normalization (ABNT, 1995), it can be seen that they can be classified as Class P and P2 mortars, due to have a compressive strength of less than 2.0 MPa and are within the range of 1.5 to 3.0 MPa, respectively. The study also allows for the assertion that the RCB can replace the natural aggregate by up to 50%, according to TR1, since it presents a significant gain in terms of much lower consumption of cement, implying a lower cost of production.

The objective of the dissertation is to analyze the quality control of the production process of profiles in steel frame and its consequences for the company Pre MoldadosPlanaltoLtda, located at Manaus - Amazonas. A review of the literature and state of the art brought significant contributions to the concepts understandings related to quality management techniques in production operations and tools for quality control and improvement. A production process description of light steel modules of the company surveyed was elaborated through documents such as laws, resolutions, standards, among others; which regulates the production process. For data collection, a questionnaire was used, with a qualitative analysis. A debate was also used to relate the theoretical basis to the results obtained through the answers of the questionnaires applied. An action plan was elaborated as a suggestion to improve the production process of the light steel modules at PréMoldadosPlanalto Ltda. The research showed that the company studied, in some way, controls the quality of its production process of light steel modules. However, some difficulties presented in the production process were evidenced, such as: the need to improve maintenance of production equipment, lack of communication among productive sectors, possible delays in the delivery of profiles to customers due to delays in the purchase of raw material, the need for training and qualification for employees in the productive sector, and the need to reduce production nonconformities. Based on these results, it can be concluded that these 06 (six) actions presented in the plan can contribute to the light steel modules production process improvement from the company surveyed. However, their results need to be implemented and studied, since this was not possible in this research.

The Basic Productive Process - PPB, as a requirement of counterpart of the benefits established by law obtained by the companies of the Industrial Pole of Manaus - PIM, has shown a complexity when applying, for example, Point and Piece Controls - CPP's, as a rule of compliance of the PPB, for motorcycles that are industrialized with the tax incentives in the Industrial Pole of Manaus - PIM. The objective of the research was to verify how much it is possible to clarify the measurement of the points and parts, which are part of these CPPs, in their minimum quantities, which are required for compliance with the PPB, in each motorcycle model. The relevance of the study consisted in demystifying what seems complex and transforming into basic information that can better clarify its application by the companies that industrialize. The research used the exploratory and descriptive, bibliographic and documentary method, with emphasis on the field work phase with as Suframa engineers and motorcycle and component manufacturers. The study sought to insert in the range of what already exists in the practice of companies and in the controls carried out by the Superintendence of the Manaus Free Zone - SUFRAMA, a proposal of improvement in the valuation of points of the parts, motorcycle components, which are part of the CPPs, through a valuation matrix, based on the application of labor, investments, plus percentages for those that are industrialized in the PIM.

Law No. 12,305 of August 2, 2010, which instituted the National Solid Waste Policy stipulated August 2014 as the deadline for municipalities throughout the country to provide for the closure of dump activities and to implement landfills. The final garbage disposal of the Metropolitan Region of Belém began in 1987, with the creation of a dump in Ananindeua, called the Aurá dump. After years of operation was deactivated the landfill began to receive treatment of controlled landfill. The production and final disposal of municipal solid waste still poses a great risk to the environment and to public health, mainly due to the formation of leachate and its infiltration. In this way, the objective of this work is to study the occurrence of contamination, to characterize the heavy metal ions in the liquid effluents that alter the composition of the soil under the landfill base and in the lagoon margin of the former urban solid waste deposit of the Metropolitan Region of (Cb), chromium (Cr), iron (Fe), aluminum (Al), manganese (Mn), nickel (Ni), lead (Pb) and (Zn) in the leachate and soil samples from the Aurá landfill, to study the adsorption process of the Cu + 2 ion on the zeolitic material, to evaluate the Cu + 2 ion removal capacity using fixed bed column zeolite, to evaluate if the levels of heavy metals determined in the percolated liquid are in conformity with the standards of discharge of effluents established by the Resolution of the National Council of the Environment - CONAMA Nº430 / 2011.

The general objective of this dissertation was to analyze in two companies in the city of Manaus how the production process of concrete blocks is characterized, demonstrating their technical viability of production. About the methodology, it is a case study carried out in the Companies A and B, located in the city of Manaus, whose main activity is the production of concrete blocks and visits to two works (Supermarket X and Condominium Y). Used concrete blocks in their constructions, which allowed to reach the objectives of this dissertation, focusing also the advantages of use coming from concrete blocks. The results reveal that the advantages of the blocks could be verified in the buildings of the Supermarket X and the Residential Building Y, emphasizing that one of the main advantages of concrete blocks is that they are leaked and allow the passage of pipes and pipes for electrical and hydraulic installations. In the A and B Companies, the production process follows the technical standards within the specifications of professionalization and mastery of the techniques, however, they present some failures related to the prototype of the concrete block, and storage of the product, as far as the palletization is concerned. However, with the implementation of the improvements presented in this dissertation, the Companies A and B, can from the redefinition of the presented prototype, with new forms and dimensions redefine the project of their families of blocks, which can be made viable on an industrial scale.

In an increasingly competitive market, small companies,do not use PCP to program and control their production to keep its market share, making them vulnerable to any oscillation in the segment they operate. Planning and controlling production are indispensable factors to obtain competitive advantage, since it is linked to the consumption control of inputs, workforce and time, which are determinant for cost composition, impacting directly on the profitability of the company; that is, by surveying the problems that occurred before the PCP was installed and excessive machine downtime was identified, mainly due to the large number of setups and color change. Besides the costs involved in the non-worked hours, an increase on the original scraps was observed, besides the setups, the cleaning of cannon and successive screen exchanges. As the selling price was calculated by the application of a factor, and without technical basis in the cost composition, the company would not survive, because the profitability was compromised by the inefficiency of the production. Since the implementation of the PCP in small companies requires unconditional support from the entrepreneur, who is active in the company, and most of the time are executors and not managers, there will be a new form of management, cost oriented, making the productive system more effective. The methodology used was through documentary research and direct observation and the contribution of the researcher's experience in several companies. The results show that with the implantation there was a reduction of 12.5 percentage points of the non-worked hours and a fulfillment of the orderbook close to 100%, when previously it was 84%, and the scraps were reduced by 22.7 percentage points . These results show that production planning and control are complex, for small firms, however, they demonstrate a significant increase in their performance even though having the financial as a limiter for systems acquisition. The proposal for the implementation and standardization of the PCP aims to eliminate the problems faced in meeting the demand of customer requests in the short term and to obtain concrete and robust information to later elaborate a medium and long term planning.

With the Brazilian economic scenario, in addition to the natural phenomena of the madeira river, the fluvial companies of fuels in the waterway of the madeira river need to reinvent to support the crisis and to project a new growth when this scenario passes. In order to have productivity in the transportation of fuels in the waterway of the madeira river, it is necessary to use the assertive means, making it compulsory to use rafts and pushers with drafts compatible with the levels of the madeira river. In the current economic scenario, in order to stay in the market, shipowners need to cut operating costs in order to deal with the reduction of freight rates charged by fuel distributors. Carrying the maximum capacity of oil rafts throughout the year is a way of minimizing operating costs, with traditional ferry models from July to October, months of the lower levels of the Reach 2 meters of draft, the average volume transported is 60% of capacity, with the same operating costs (consumption, payroll, food, surveys and etc). Ferries with a mean draft of 2.20 M allow the transport of fuel in the waterway of Madeira, profitable for the shipowners of the region.

Whose model of construction system arose in the prehistoric period brings in its context the general objective the use of waterproofing in buildings in taipa, to eliminate the unwanted infiltrations and as specific objectives the identification of Waterproofing products suitable for application in buildings built in mud; Test two waterproofing products that provide adhesion and tightness; To analyze if the specific properties of each product are compatible in the waterproofing of buildings in mud and, lastly; Compare and record the results obtained in the research that contribute to the preservation of the buildings in taipa, guaranteeing the durability, efficiency and comfort with the elimination of infiltrations. The methodology used was based on the applied research and bibliographical research in works of expertises both in the civil construction in the area of waterproofing, anchored in the extensive and judicious legislation that beacon the technical procedures that were used by the researcher during the development of the work
that culminated with the edification Of a plasterboard bath with coating in two types of waterproofing products, duly tested and whose results were fully successful in the sealing tests, isolating, the probable infiltrations originating from the natural humidity in the State of Amazonas, in the city of Manaus, caused by the high rainfall and flooding of the mighty Rio Negro that surrounds the capital.

The decision by the construction companies of the city of Manaus / AM not to use the Production Project in their productive environments has been responsible for large losses in the Civil Construction Industry environment, mainly in the substructure of Masonry of Fences, where there is Need for considerable amount of people and materials. Among the possible reasons are the superficial idea that these projects are expensive and because they are not budgeted, can not be passed on to the client, or that the professionals responsible for the execution have the experience to perform their duties. It happens that the absence of projects for the masonry process of fences, for example, impacts on the exaggerated consumption of materials, burdening the real costs and forcing the construction company to opt for other less healthy forms of adequacy of the financial planning, when necessary, Such as the use of cheaper materials, the use of less productive tools or the use of labor with little technical knowledge. In this case, decisions are based on the experience of the mason and master builder, providing significant margin of error, and attracting "rework". The lack of organization, qualified and skilled personnel and the use of random materials and methods compromise the work, directly affecting: the execution time; The quality of the final product, and the costs in general, nullifying the productivity planned and required for the enterprise.

The strengthening of agroindustry presents itself as an economic alternative for the municipality of Benjamin Constant, Amazonas, to reduce its high dependence on government accounts. However, the implementation of any type of business in the Amazon region is challenging, given the high logistics costs. Hence, it is believed that developing a holistic view of the problem through management tools such as Supply Chain Management or even Integrated Logistics come as alternatives to provide a number of ways in which companies can increase productivity and, As a consequence, contribute significantly to the reduction of costs, as well as to identify ways of adding value to the products. This research analyzed the impact of logistic costs on the industrial processes carried out by a fruit pulp agroindustry located in the municipality of Benjamin Constant, Amazonas, seeking to identify the Supply Chain; Analyze Stock Management; Assess the impact of logistics costs on the product pricing process; Propose an improvement plan for Supply Chain Management. In order to do so, a research of the exploratory and explanatory type was carried out, in the combined form (qualitative and quantitative), having as a research method a Case Study, using interviews, observations and archive information (documentary research) for data collection . Thus, one can identify the main potential and logistical threats to the implantation, consolidation and maintenance of an Agroindustry of fruit Pulp in the municipality; As well as to propose a plan to improve Supply Chain Management, aiming at reducing logistical costs and, consequently, optimizing manufacturing and distribution processes. With this, it is believed that it is contributing to the strengthening of the local industry, increasing employment and income improvement to the population of the municipality, and also, justifying the need for public investment in the improvement of the logistics infrastructure of the Amazon region. 

Nowadays, the computer is present in the everyday life of people in any activity, be it at work, at home, at school or even on the street. Often making the execution of an activity impossible without this equipment. The study that will be presented is limited to computerized positions indoors, more specifically in offices, where there is still a certain freedom in the use of computers. However, the incidence of Repetitive Strain Injuries (RSI) and Work-Related Osteomuscular Disorders (DORS) is observed. The objective of this study is to identify and analyze all situations that pose a risk to workers' health from an ergonomic point of view in the administrative sector of a lubricant distribution company (Manaus AM), as well as to suggest changes that may minimize the impacts of the work Computerized. To do so, we investigated complaints and the Rapid Upper Limb Assessment (RULA) and Sue Rodgers assessment tools to diagnose possible musculoskeletal lesions caused by the activity and / or acquired postural defects.

The present paper aims to show the use of diffuse logic in order to reduce the subjectivity of options and judgments in maintenance management in automated production processes aiming the occurrence of failures in the application of weld (SMD), demonstrating an applicable methodology for use with targets In the action of quantifying with certain, relevant aspects and avoiding criteria that appear with subjective evaluations. For that, we chose a case study, based on its exploratory and descriptive applicability. Initially, the process of researching data, previously collected in the organization routines was adopted. This collection used the interval from January 2015 to January 2016. Due to the weak and inconsistent data base, it was necessary to map the process, define qualitative indicators and the respective targets, so that it was possible to measure work activities. We used the quality tools Ishikawa Diagram, Pareto Diagram and Variable Control Chart, highlighting the "weld ability failure" defect as the main parameter to evaluate the performance of this study. It is concluded that after the modeling of the system and its due diligence when applying the concepts of the diffuse diagram, the company added: significant reduction in the volumes of failures highlighted, greater understanding of the phenomena involving the failures and their effective solution, avoiding recurrences.

The present work sought to answer the questioning about the effectiveness of the use of quality tools in an automotive industrial company. For that, using a qualitative and descriptive methodology, a follow-up of the production activities of a motorcycle assembly company of Polo Industrial de Manaus was carried out for six months, in order to identify, analyze and prove the knowledge and the use quality tools in industrial production activities. In a broader approach, it was also sought to evaluate the man-process-quality-improvement correlation from the field studied. At experimental levels, it was verified that the systematized application of the quality tools led to highly satisfactory results, with qualitative improvements of around 18% and a return over investment of a few weeks, justifying and enhancing the use of works with the use of those tools. In addition, it was verified that due to the effectiveness achieved and the simplicity of the use of the tools, the motivational and integrative aspects of the human element to its work within the operational routines can be directed towards the quality and for the continuous improvement so necessary for excellence and the survival of an organization.

In a global economy and in face of such a complicated world scenario, searching for differentiation means having advantages so that one can survive. Increasingly, organizations require a greater alignment when devising strategic planning such as making investment plans, opening or expanding new markets, and launching new products or services. In order to execute a strategic plan the departments in an organization need to be in compliance with each other. Therefore, the sales process needs to be aligned with the production process, which in turn should be aligned with the purchasing process and logistics, and so forth. This way the process is continued and its execution plan is made possible. Otherwise, it is precluded. In this process, the marketing, logistics and production departments should constantly seek to reduce costs, optimize production, generate production efficiency, and differentiate its products. In face of this view, this study aims to correlate how logistics management process affects the ‘Four Ps’ which include price, product, place and promotion. Consideration will be given on how to transform logistics management process in strategic factor so that organizations can be placed through marketing, logistics, and production department interface. This study also aims to give a valuable contribution to the theme studied as well as to contribute to the logistics management process development as a strategic factor in organizations.

The dispute over a space of medicinal cosmetics for the use of native plants of the Brazilian Amazon has increased considerably and this has made scholars and researchers of the branch seek the use of these plants as competitive advantages within a successful business. In order for these expectations to be achieved, it is necessary to apply automated machines, which will certainly respond to the research and profitability of entrepreneurs in a short time. This dissertation aims to develop a platform with several integrated modules of automated machines to be used in the extraction of vegetable oil such as murumuru, buriti, babassu, coco, tucumã, andiroba, among others that will certainly bring many benefits to those who are in the primary sector without support for their production. However, their products will have more qualities and great profits, exclusion of slave labor and more time for their families. This platform of integrated machines was carried out from an exploratory research of the operation of each one through the basic characteristics already known inserted in its manuals, concomitant with the actions of control through the techniques of automation and the programming of Human Machine Interface (HMI). However, this research was directed as an experiment from the andiroba almonds, as a starting point due to the ease of finding the almonds to facilitate the observation of the results. As for the handling of the operations of the machines during the production process, that will be not necessary since, once they are programmed, they work directly until their sensors detect a lack of material or a break in some device, but the operators will be properly trained in the whole production process, generating employment with adequate training and income for the region. In spite of the technological advances, the deficiencies are many, both in the studies directed to attenuate the contamination of vegetal oils, as in the bottlenecks of the chain of production of the traditional process that prevent the quality in the extraction of the mentioned vegetal oils. Therefore, the final representation of the productive process chain involves the physical understanding of the electro-electronic actions, automation, mechatronics and mechanics with low maintenance costs, to produce one liter of oil every 4 hours as the initial goal. Starting from this context, the innovative technologies using an almond washing system, conveyor with convention heater, crusher and centrifuge, all integrated.This process will require the operator to be highly qualified, since he will deal with a program through a Human Machine Interface (HMI), with the mission of controlling the entire thermal profile to meet the requirements of vegetable almonds, and in this way master all the integrity of the heating zones, parameterization of process information, visual and sound alarms with safety.

In Western countries, including Brazil, there are many companies that seek to implement the Japanese management philosophy, known as lean manufacturing, and its principles, aiming to achieve better results based on the reduction of waste, from this it was proposed the implementation of the pull system in an industry of paints with the objective of demonstrating the impact of this implantation in the levels of stock and the attendance to the requests of the clients, since unnecessary stocks end up generating great costs of maintenance and storage, as well as risk of losses by deterioration and, nevertheless , do not guarantee good customer service. For this, a mapping of all the company's processes was carried out, identifying and eliminating steps that do not add value to the customer, then the changes were proposed and implemented so that the order fulfillment would happen according to just in time, that is, At the right time and in the desired quantity, replacing the traditional pushed production system. The results were able to demonstrate the efficiency of the pull system, which reduced the inventory levels by 15% and increased the customer service index from 92% to 97%, breaking the paradigm that to have good service it is necessary to raise The inventories, being the fundamental to have an efficient supply dynamics, as proposed by the pull system.

After 1951, when the first TV sets were produced in Brazil, it became one of the most affordable products of the Brazilian market, since it represents the second most purchased electronic equipment in Brazil (IBGE, 2015). To meet this demand of the consumer market, It becames necessary to improve the process of production quality of the companies. According to Roth (2011), the total quality is an effective system for the integration of the development efforts of the quality of several groups at an organization, to allow cost-effective products and services considering the customer’s complete fulfillment. One of these quality groups aims for the finished product, since it is about the Internal Buyer Inspection Team (IBI) that performs the last battery of tests of the product done, regarding the main features of the TV set, which means to simulate the executing actions of the customer’s behavior, like: turning the TV on and off, turning the volume up and down, changing channels, mute function, plugging and umpplugging it, and also swapping voltage 110 or 220v. These testings encumbers, meaningfully the efforts of the testing team. To reduce the efforts of the testing team (IBI), the aim of this research is to develop a workflow for the execution of test of quality of finished products aiming to automate the
Buyer’s internal inspection tests process reliably and successfully.

The Lean Manufacturing philosophy as a management system is helping to make industries more competitive and innovative, making processes leaner and increasing production capacity. There is no everyday on the factory floor due to better results, especially in the assembly line balance, instigating the engineers and manufacturing technicians or the challenge of introducing the non-process concept. The objective of this paper is to present an experience of increasing productivity and capacity of air conditioning production lines, from a multinational company located in the state of Amazonas, as a case study applying lean manufacturing concepts using a VSM Map tool). Allows us to map the current state of production lines, sketch the process load graph and through the assembled action plan to design a future state. As a main conclusion of the work, it was verified that this approach allowed for a non-value-added increase in operations, through a better flow of materials with changes in strategic layouts and elimination of wastes, leading to increased capacity for better operational results. A great financial return for a company.

In the current economic scenario that Brazil is going through, together with the increasingly competitive global market, reducing scrap, increasing profitability and increasing the quality of products and services, becomes essential for the survival of organizations. As a result, Brazilian companies are seeking to adapt to this new market reality, seeking improvements in their processes that reflect good yields and minimize the percentage of waste. In this study, the objective is to create a viable method, using Lean Manufacturing concepts, to improve the process in the reuse and reduction of metal scrap. The methodology applied to the research is qualitative and quantitative bibliographical, with participant observation. Methodologies were adopted, including the set of good practices, process evaluation and the development of improvement tools. Historical data on the consumption of raw materials, iron and steel were used, as well as an understanding of how productivity management occurs in the organization. As a result it was possible to verify that the wastage of materials was more than 7% of the produced.

The present dissertation aims to implement the evaporator unities' test monitoring and interconnect them to the MES system, in order to improve the process with emphasis on quality to clearly demonstrate the performance testing on the product, which is the evaporating unit (inside the split product). The test is executed during its assembly process at the "Run Test" sector. It enables the identification of the product's functionality and its communication with the condensing unit (outside of the split product): also, the test used to be conducted manually by operators, resulting in no guarantees that 100% of the products were actually tested. In this way, the problems were only identified by the final consumer, endangering the credibility of the brand and increasing SCAPS. Through the improvement presented by an automated process, designed to develop communication with the MES system (Manufacturing Execution System), the system performs a product traceability, which impedes a malfunctioning product to proceed, once the "Run Test" is connected to it and immediately identifies the fault, disapproving and blocking the failing product, preventing it to pass to the next steps of the process, until it is rectified and reworked to eliminate the failure: this improvement increased productivity in a certain company, as well as proportionated greater market competitiveness, observing the quality criteria demanded by consumers without omitting employees safety during all assembly steps.

Nas últimas duas décadas, vários estudos sobre a concentração e fluxo de gases de efeito estufa (especialmente CO2 e CH4) têm sido realizados, em lagos e rios naturais e represas em todo o mundo, mostrando que estes ambientes podem contribuir de forma significativa para o efeito estufa. Os ambientes aquáticos produzem estes gases biogênicos no processo de decomposição da matéria orgânica produzida dentro do ambiente (autóctone) ou na que é importada da bacia de drenagem (alóctone). Estima-se que estes ambientes contribuem com cerca de 40% da emissão global de metano para a atmosfera. Várias cidades no mundo a fim de diminuir essa problemática, estão aproveitando dos aterros para gerar energia elétrica e ainda comercializando essa energia renovável. Sobretudo, isso seria de essencial relevância à Manaus, pois sendo a maior capital da floresta Amazônica o beneficio seria em larga escala. Objetivo do trabalho é fazer uma proposta de geração de energia alternativa sustentável por meio do gás metano no aterro sanitário, baseada em dados do município de Manaus. A metodologia aplicada se deu por meio da pesquisa in loco nos setores dos governos municipal, estadual e federal para descobrir se Manaus está dentro dos parâmetros mínimos e a análise de dados dos resíduos sólidos, universo da pesquisa e a descrição detalhada da análise de dados. Os resultados obtidos foram que Manaus hoje gera em torno de 2.632,156 t/dia, sendo coleta domiciliar, coleta hospitalar, remoção mecânica, remoção manual, coleto de poda, coleta seletiva e terceiro.

Armazenar e tratar os resíduos industriais produzidos em grande escala é importante sob o ponto de vista de se evitar que os mesmos ofereçam riscos ao meio ambiente, principalmente com relação ao solo e aos rios. Sendo o principal processo de produção de alumina a partir do minério de bauxita, o processo Bayer gera grande quantidade de resíduo de bauxita (lama vermelha). Este trabalho estuda a redução da alcalinidade do resíduo do processo Bayer, a ponto de mantê-lo em nível baixo de reatividade por meio da injeção de dióxido de carbono gasoso, com acréscimo de óxido de cálcio reagindo em reator tipo torre de borbulhamento, e a formação de compostos minerais estáveis, sendo necessário acompanhar o decréscimo do comportamento no valor do pH da suspensão ao longo do tempo. O óxido de cálcio adicionado, juntamente com a carbonatação, influenciou diretamente no meio alcalino do resíduo de bauxita Bayer ao longo do tempo de monitoramento de aproximadamente 15 meses, reduzindo a alcalinidade da suspensão de 13 para 8,5 na faixa de pH. A alcalinidade do resíduo de bauxita Bayer estabilizada em pH 8,5 é importante para que este material não ofereça
tantos riscos ambientais e possa ser utilizado em outros processos industriais.

O Parque Industrial de Manaus possui várias fábricas com processos de produção modernos, e também alguns equipamentos bastante antigos que estão sendo substituídos gradativamente por equipamentos mais novos, com mais tecnologia, melhorando a produção, ergonomicamente melhores, e com nível de ruídos menores. Porém, mesmo os equipamentos mais modernos ainda emitem ruídos em níveis que são prejudiciais ao trabalhador e ao meio ambiente, pois causam poluição sonora. E em alguns processos de fabricação, mesmo com equipamentos ou máquinas modernas, os níveis de ruído não reduzem muito, devido o processo especificamente. Neste contexto, este trabalho mostra quais os problemas de saúde que o trabalhador adquire devido a sua exposição ao ruído, com maior ênfase aos trabalhadores que operam máquinas injetoras. A escolha das máquinas injetoras, é porque são equipamentos que estão presentes na maioria das fábricas do Polo Industrial de Manaus, desde as empresas terceirizadas que fornecem componentes, até gigantes como as montadoras do polo de duas rodas. O ruído é um agente físico que está presente em todos os ambientes de trabalho, e em uma sala de máquinas injetoras ele é intenso quando são ligados os equipamentos, acompanhando o trabalhador durante toda a sua jornada.

A grande maioria dos processos utilizados na indústria da construção civil, tem no seu ciclo produtivo a geração de grande quantidade de resíduos, e, como consequência a poluição ambiental, afetando a qualidade de vida da população residente nessas regiões. O desconhecimento ou a inexistência de tecnologias apropriadas ao reaproveitamento desses resíduos e o não cumprimento das leis de preservação do meio ambiente, são os responsáveis pela deposição inadequada na natureza, impactando-a e criando inúmeros problemas. A reutilização de uma parcela significativa desses resíduos, mais especificamente as originadas de resíduo de concreto, pode e deve ser utilizada como agregado em dosagem de concreto estrutural, que, por falta de conhecimento técnico apropriado à reutilização, são descartados e classificados como sendo de baixa qualidade. Demonstra-se, com base em pesquisa bibliográfica e teórico experimental, que estudos das propriedades do agregado e do concreto reciclado, são necessários para um melhor entendimento. Apresentamos resultados de uma investigação das características granulométricas e físicas dos agregados miúdo e graúdo reciclado, obtidos a partir de processos de beneficiamento de resíduos de concreto obtidos de corpos de prova de concreto ensaiados no Instituto Federal do Amazonas – IFAM. Os resultados demonstram que há necessidade de se repensar a reutilização desses resíduos pela sua extrema importância, no momento em que se aliviam os impactos ocasionados ao meio ambiente. Com relação ao caráter econômico, estaremos agregando valor, a um produto descartado e que tem potencial de reutilização.

A ergonomia contribui para o incremento da produtividade e melhoria da saúde dos trabalhadores, diminuindo a incidência dos problemas de lesões por esforços repetitivos/trauma cumulativo. Neste estudo a ergonomia aplicada é a biomecânica ocupacional por estudar as interações entre homem-máquina-ambiente, sob o ponto de vista da postura e movimento músculo - esquelético e sua consequência. O objetivo geral é alcançar a redução de trabalho sem sobrecargas nos membros das colaboradoras do posto de embalagem de canetas, utilizando os métodos da ergonomia e ferramentas de Moore & Garg e NIOSH, resultados conseguidos da implementação da metodologia PDCA. A metodologia aplicada à pesquisa é bibliográfica de natureza qualitativa e quantitativa, com observação participante, e vária outras metodologias, dentre as quais a metodologia PDCA para direcionar a AET e solucionar problemas com a ajuda de técnicas de brainstorning, gráfico de Ishikawa, 5W2H. Também foram utilizadas as ferramentas de critério de Moore & Garg e NIOSH para quantificar a tarefa quanto ao risco de sobrecarga aos membros dos funcionários. Adotou-se o ciclo do PDCA por ser um método de gerenciamento plenamente executável e, quando posto em prática, com eficiência resulta em satisfação, como é caso do estudo que através da reavaliação das tarefas com uso da ferramenta NIOSH (análise de levantamento de carga na tarefa de colocar caixa na esteira) e Moore & Garg (análise de sobrecarga nos membros superiores na tarefa de encher cartuchos com canetas), potencializaram as tarefas de baixo risco quanto ao aparecimento de lesões por esforços repetitivos (LER) /distúrbios osteomusculares relacionados ao trabalho (DORT).

Este trabalho propõe o desenvolvimento e a implementação de um controlador baseado em lógica fuzzy capaz de manter estável o nível de tensão do barramento CC de um conversor de frequência (CF) de uso comercial usado para acoplar geradores fotovoltaicos a motobombas centrífugas comerciais para fins de bombeamento de água. O sistema opera em malha fechada e a regulação da tensão do barramento CC é feita indiretamente através da variação da velocidade da motobomba de acordo com a potência disponibilizada pelo gerador fotovoltaico. O objetivo é fazer com que o gerador trabalhe em uma tensão fixa, correspondente a tensão do ponto de máxima potência ou bem próxima, a fim de maximizar a eficiência e prevenir desarmes do sistema por erros de subtensão no circuito intermediário do CF. O algoritmo de controle foi embarcado em um microcontrolador PIC de uso geral e avaliações do desempenho do controlador foram efetuadas através de ensaios experimentais realizados em uma bancada que permite simular poços de diferentes profundidades. Os resultados experimentais mostraram que o controlador teve o comportamento esperado, pois manteve a tensão do barramento CC estável, próximo a tensão do ponto de máxima potência, durante todo o ciclo de bombeamento mesmo ocorrendo mudanças drásticas na disponibilidade de potência fornecida pelo gerador fotovoltaico.

A destilação atmosférica de petróleo representa o processo essencial no refino e possui características complexas, devido à quantidade de variáveis do sistema. Por isso, é necessário conhecer os parâmetros de refino para identificar as variáveis mais significativas e alcançar resultados otimizados. Esta pesquisa teve como objetivo a avaliação do comportamento das principais variáveis do processo de destilação de petróleo a partir do modelo simulado no software Petro-SIM, garantindo a otimização de produto da destilação através da aplicação das técnicas de meta-heurísticas. Inicialmente realizou-se o levantamento das variáveis operacionais Xi, sendo elas: o refluxo de querosene e diesel e a temperatura de topo da coluna. Aplicou-se o planejamento fatorial do tipo 2K+Estrela para estas três variáveis. Na simulação obtiveram-se os valores para as variáveis dependentes (Yi) e as restrições (Zi) do sistema. O gráfico de Pareto e a análise de variância identificaram a temperatura de topo como sendo o fator mais significativo do sistema. Foi aplicado o método de filtro de partículas para garantir a aproximação do modelo matemático. A aplicação das técnicas de otimização por algoritmos genéticos e recozimento simulado identificou a maximização da vazão de diesel em 1281,7 m3 /d, garantindo os limites das restrições de qualidade do produto.

Constituído por instalações de água fria, água quente, esgotos e águas pluviais, o sistema predial hidráulico e sanitário é um dos que entram em contato direto com o usuários e seu mau funcionamento é um indicativo de existência de patologias que resultam em queda do bem estar físico e psicológico das pessoas. Esse estudo teve como objetivo, identificar e diagnosticar as manifestações patológicas hidro-sanitárias em edifícios residenciais verticais e propor soluções terapêuticas.  Foram realizadas entrevistas com  responsáveis pela manutenção preditiva de nove (09) prédios localizados na zona centro-sul de Manaus (AM), seguidas de visitas técnicas em cada um deles. O trabalho possibilitou o conhecimento das principais manifestações patológicas hidro-sanitárias, como o mau cheiro, falta d’água, obstrução em tubulações, ruídos e retorno de espuma, entre outras, possibilitando observar a influência de fatores como projeto, materiais aplicados, execução e manutenção. O conhecimento das principais patologias indicadas pelos entrevistados e avaliadas durante as visitas evidenciou a importância da observação às recomendações normativas de projeto e execução, o que ajudou a expor a necessidade de prevenção de todas as falhas que se tornam problemas, resultando em falta de desempenho e, finalmente, originando as patologias que acometem os edifícios residenciais.

Este trabalho apresenta o desenvolvimento de uma proposta de modificação no sistema de controle de pressão da fornalha da Caldeira DZ na refinaria Hydro Alunorte, com objetivo de solucionar problemas de instabilidade deste sistema durante as variações de carga da caldeira. Com esta implementação, além de contribuir para a estabilidade e controle do processo, proporcionou o aumento de velocidade de resposta da caldeira ás variações da demanda de vapor exigidas pela refinaria, implicando em aumento da confiabilidade operacional, retomada da operação automática do sistema de combustão e controle do oxigênio.
A escolha da metodologia para implantação da estratégia de controle feedforward ao projeto de controle de pressão da fornalha da caldeira foi devido a sua capacidade de resolver diversos tipos de problemas em várias aplicações da engenharia, em especial nos relacionados ao controle de processos. Os resultados alcançados foram satisfatórios e contribuíram para um melhor desempenho operacional da caldeira aumentando a estabilidade do sistema de geração de vapor da refinaria.

O simulador da concentração de sólidos no processo produtivo da precipitação é baseado num modelo realizado através de balanços mássicos nos tanques, onde se houve a necessidade de atuar para alavancar o nível de produção diante do mercado concorrido. O simulador terá bases na nucleação, crescimento, quebra, aglomeração, solubilidade e em grande parte processo de cristalização nós precipitadores. O modelo foi usado para resolver um grande problema na variável de processo (Concentração de Massa na Cadeia Produtiva da Precipitação), devido suas grandes variações e perdas e assim prever o comportamento da produção em todo circuito até sua etapa final. Através dessas soluções, resultados numéricos e laboratoriais foram obtidos e comparados, permitindo assim uma avaliação crítica da presente metodologia da solução.

O presente estudo analisa o sistema de resfriamento de uma planta de compressores de ar da refinaria de alumina Hydro Alunorte, tendo como propósito a identificação de alternativas para o sistema de resfriamento das máquinas de forma a evitar aquecimento fora das condições normais de operação. Devido a esse aquecimento, além do alto consumo de energia no processo, as máquinas têm um grande percentual de queima de componentes e o ar é produzido com uma relação de umidade maior do que a desejável. Foi realizado este estudo para analisar o processo atual, a fim de identificar as causas do sobreaquecimento dos compressores de ar e avaliar a eficiência do sistema de resfriamento, bem como a influência da qualidade da água. Essa avaliação levou à proposta de implementação de bateria de trocadores de calor à placas, no intermédio do circuito entre a planta de compressores e as torres de resfriamento, objetivando eliminar o plano de limpeza periódica dos trocadores de calor do sistema de resfriamento de cada compressor, reduzindo de indisponibilidade física dos equipamentos, em razão da eliminação da contaminação da água de resfriamento dos compressores e aumentando a eficiência da troca térmica em razão da utilização de água livre de contaminação no circuito fechado entre os trocadores de calor e os compressores de ar.

A cal caracteriza-se como um importante insumo nas refinarias de alumina, pois ela contribui fortemente no controle de impurezas que em determinadas etapas do processo podem prejudicar o fluxo de produção, assim como na estabilidade do licor. Na Hydro Alunorte existe uma área própria para a extinção da cal virgem que atualmente não consegue atender a demanda máxima de leite de cal preparado exigida pelo processo. Eventualmente, a produção precisa ser reduzida, principalmente quando um dos moinhos de cal é submetido a desincrustação mecânica devido a elevada taxa de incrustação presente no seu sistema de recalque. Este estudo propõe-se a entender a fonte causadora desta incrustação, avaliar possíveis meios de mitigá-la, senão avaliar outras formas mais rápidas de limpeza deste sistema. Amostras de crosta de cal foram analisadas e os resultados obtidos levaram a necessidade de avaliar a composição química da água. O estudo sugere ser o teor de carbonato na água a principal fonte de incrustação do sistema. Foi realizado um planejamento de experimento com o objetivo de avaliar em laboratório a degradação da crosta de cal em solução cáustica, já que a aplicação desta solução para a limpeza na refinaria seria de baixo custo, e o resultado apresentou-se favorável.

A presente pesquisa realizou um estudo de uso de aditivos poliméricos, tais como o tanino e o poliacrilato de sódio, com a finalidade de substituir os compostos de sulfato de alumínio que são utilizados nas Estações de Tratamento de Água. Para isso, foi realizado um estudo de caso, na Estação de Tratamento de água do Terminal Petroquímico de Miramar, o qual é administrado pela Companhia Docas do Pará, neste local, foi realizada a coleta de água bruta que passou por análises físico-químicas com a finalidade de verificar a qualidade de água que é captada do poço n.º 3 dessa Estação de Tratamento. Em seguida, realizaram-se os ensaios do Tipo Jar Test ou Teste de Jarros que é um método de simulação dos processos de coagulação e floculação, realizada em nível de laboratório que permite obter água de boa qualidade facilmente separada por decantação. Essa simulação teve como objetivo a realização de uma análise comparativa entre o sulfato de alumínio, o tanino e o poliacrilato de sódio buscando verificar a viabilidade técnica de substituir o sulfato de alumínio. Após essa etapa, realizou-se uma análise comparativa entre os três produtos utilizados com a finalidade de comprovar a viabilidade econômica de substituição do sulfato de alumínio. Neste sentido, pode-se
observar que as análises realizadas com o Tanino apresentaram os melhores resultados de remoção de cor e turbidez, dando à água tratada as características físico-químicas recomendadas em termos da legislação vigente. Pode-se observar que, economicamente o custo do Tratamento de água com o Tanino é maior do que o sulfato de alumínio, quando a análise é realizada em curto prazo. No entanto ao longo prazo a substituição do sulfato de alumínio pelo Tanino é viável, uma vez que a quantidade de lodo gerado no tratamento de água é menor quando comparado com o sulfato de alumínio, ou seja, o custo com o tratamento do resíduo gerado é menor, assim como a destinação final.

A precipitação é parte do processo Bayer onde a produtividade da planta e a qualidade da alumina (índice de atrito soda ocluída e granulometria) são definidos. Ela opera não com valores alvo absoluto, mas sim dentro de faixas, pois, o circuito é dinâmico, o licor muda de composição (assim como a bauxita e etc). Devido a complexidade no controle de processo da precipitação é imprescindível que o engenheiro de processo tenha uma ferramenta que possa lhe ajudar nas tomadas de decisão. O objetivo desse trabalho é desenvolver um aplicativo computacional que possa auxiliar o engenheiro de processo nas tomadas de decisão do dia a dia. A

A Hydro Alunorte é a maior refinaria de Alumina do mundo com uma capacidade de produção aproximada de uma tonelada a cada cinco segundos. Uma característica do processo produtivo da refinaria (Processo Bayer) é a alta sensibilidade operacional à falta de energia elétrica gerando uma descontinuidade na produção. O cenário atual da matriz energética, indicando um possível racionamento ou riscos de sobrecargas no Sistema Interligado Nacional (SIN), devido a atrasos em projetos de usinas geradoras e linhas de transmissão, adicionados aos baixos níveis dos principais reservatórios das usinas Hidrelétricas nas regiões Sul e Sudeste, elevam os riscos de perdas de produção associados a falta de energia elétrica. Com o objetivo de mitigar estas perdas de produção este trabalho apresenta uma ferramenta para diagnosticar e recompor de forma automática o sistema elétrico após uma falta de energia através do Sistema Digital de Controle Distribuído (SDCD), reduzindo o tempo para análise e recomposição e consequentemente reduzindo as perdas de produção. Como metodologia foram definidos os equipamentos elétricos e subestações que possuem tecnologia atualizada e estratégicas no processo produtivo, gerando desta forma um custo mínimo de investimento para implantação com resultados direto nos valores de perdas de produção. A aplicação da lógica Fuzzy para detecção, diagnósticos e atuação sobre a subestação estudada resulta num sistema completo de supervisão auxiliando o operador do sistema elétrico da Hydro Alunorte.

O cenário elétrico atualmente vem mostrando uma forte instabilidade na geração de energia devido ao baixo nível dos reservatórios das usinas hidroelétricas das regiões Sudeste e Nordeste, o que expõe o sistema interligado nacional a possíveis “apagões”, uma vez que a geração de energia elétrica nacional é majoritariamente hidroelétrica. Essa situação é bastante crítica para indústrias de grande porte com processo produtivo contínuo que em caso de parada de uma parte do processo, este pode levar bastante tempo para retomar o ritmo nominal, o que normalmente acarreta em grandes prejuízos. As refinarias de alumina enquadram-se nesta categoria e, em particular, há uma área bastante sensível, a da precipitação, que no caso da falta de energia por um período maior que 10 (dez) minutos provavelmente terá perdas de produção por alguns meses. Sendo assim, é fundamental disponibilizar energia elétrica para a precipitação em menos de 10 (dez) minutos após a ocorrência. No caso de falta total de energia elétrica, o reestabelecimento ocorre através de manobras pré-definidas para fornecimento de energia através da usina de geração de emergência e no caso de falta parcial, ou seja, apenas uma parte da área é desenergizada, o reestabelecimento ocorre através de manobras pré-definidas no interior das subestações. Atualmente essas manobras são realizadas pelos eletricistas/operadores que, em muitos casos e por diferentes razões, acabam errando e, consequentemente, não conseguem disponibilizar a energia vii rapidamente causando grandes impactos para a companhia. O objetivo deste trabalho é desenvolver uma lógica para automatização dessas manobras, utilizando o controlador central da planta para supervisionar e atuar quando necessário, retirando assim as responsabilidades das manobras dos eletricistas/operadores. Com isso, busca-se reduzir o tempo de indisponibilidade de energia e, consequentemente, uma maior disponibilidade operacional.

O uso de materiais como carga em compósitos poliméricos é cada vez mais incentivado do ponto de vista ambiental, visando à sustentabilidade. A utilização da lama vermelha resíduo do processo Bayer, como carga é alinhada aos interesses da indústria de compósitos, somadas as opções de destino dos resíduos pela indústria metalúrgica. A fibra de curauá Ananas lucidus, Mill, é um material de potencial reforço em compósito polimérico com o poliéster isofitálico. Neste sentido, o presente trabalho apresenta estudos que elucidam a influência da aplicação destes materiais nas propriedades físicas e mecânicas, como massa específica, porosidade, módulo de elasticidade e resistência a tração respectivamente. Para tal, foram fabricados compósitos variando-se o percentual da fração volumétrica de lama vermelha na faixa de 0% a 30%, e compósitos com lama vermelha e fibra de curauá, mantendo-se fixa a fração volumétrica de fibra de curauá em 10%. Os compósitos foram efetuados em duas etapas: em que na primeira etapa utilizou-se o processo Hand-lay-up (manual) para o preparo da resina, mistura e a aplicação da fase dispersa. Na segunda etapa foi usada a moldagem sobre pressão de 0,5 MPa, e analisados segundo norma ASTM 3039 os ensaios de tração. Os resultados mostraram que ocorre a redução da massa específica e aumento da porosidade com a adição de fibra de curauá, e a redução da resistência tração com o aumento de lama vermelha e do Módulo de Young, e através da análise morfológica das fraturas dos materiais por microscopia eletrônica de varredura (MEV), observou-se melhoria na adesão fibra/lama/matriz robustecendo a evidencia dos resultados.

Mediante as novas exigências do mercado consumidor, tornou-se necessário que as mudanças nos processos produtivos nas indústrias sejam rápidas o bastante para não perderem mercado consumidor, e sistemático, a fim de minimizar os impactos causados pelas mudanças na qualidade do produto final oferecido ao cliente. Neste sentido, este trabalho investiga a implementação de um sistema fuzzy em um ambiente simulado para o controle da área superficial da alumina. A escolha da metodologia fuzzy deu-se devido a sua capacidade de resolver diversos tipos de problemas em várias aplicações de engenharia, em especial nos relacionados ao controle de processos. O raciocínio aproximado da lógica fuzzy fornece uma maneira de compreender o comportamento do sistema, a partir de experiências vividas por pessoas que estão diretamente envolvidas nas operações de chão de fábrica, permitindo a interpolação aproximada entre situações observadas. Primeiramente, são discutidos os impactos que a variável área superficial acarreta no processo produtivo da alumina e como a escolha dos set points de temperatura e pressão pode influenciar no controle da área superficial. Em seguida, são analisados quais variáveis de processo podem ser utilizadas como parâmetros para
serem as entradas do sistema e como esse controle é feito atualmente. O próximo passo foi a criação de uma base de regras a partir da experiência dos engenheiros e especialistas de processo. Feito isso, foi criado um sistema fuzzy utilizando o software Matlab®, para proposição dos set points da temperatura e pressão. Com o intuito de melhorar a assertividade da base de regra criada, algumas regras foram ajustadas pela técnica look up table sendo utilizada base de dados coletados no período de Janeiro a Dezembro de 2014. As comparações dos resultados obtidos por simulação confirmam o bom desempenho do sistema desenvolvido.

A técnica da transformada de Laplace com inversão numérica foi usada para resolver uma equação integro-diferencial parcial que relaciona a modelagem matemática do problema físico para estudar processos convectivos com taxas de nascimento e morte de partículas e aerossóis. Tal modelo é governado PBE, na qual leva em consideração a nucleação, crescimento e processos de coagulação. Um método Bayesiano foi usado para resolver o problema inverso hiperbólico e não-linear, e estimar a função densidade de tamanho de partículas, e assim prever o comportamento dinâmico do sistema físico. Especificamente, o filtro de partículas com Amostragem e
Reamostragem por Importância Auxiliar (ASIR) foi utilizado como metodologia de solução do problema. Por meio dessas soluções, resultados numéricos foram obtidos e comparados com os disponíveis na literatura para sistemas particulados, permitindo uma avaliação crítica da presente metodologia de solução.

A lavagem cáustica é fundamental para as rotinas de uma planta Bayer, limpando equipamentos e sistemas de tubulações que possibilitam a boa operacionalidade das etapas do processo. Para que isso possa acontecer, é essencial o controle da temperatura e da concentração cáustica no processo de limpeza, sendo esse o binômio que garantirá a eficiência da solução. Este estudo mostra que a manutenção da temperatura em patamares de 80°C proporcionará condições para um bom controle da concentração cáustica, e que a variável tempo de limpeza perde importância se temperatura e concentração caustica não estiverem nas faixas de controle estabelecidas. Também mostra que em rotinas onde a solução de limpeza é preparada com soda virgem e licor Bayer (licor pobre), a capacidade de dissolução da solução diminui significativamente em temperaturas abaixo de 75°C.
