Item Acesso aberto (Open Access) Análise da eficiência dos protetores auditivos utilizados na indústria da construção civil na cidade de Manaus(Universidade Federal do Pará, 2019-02-20) AMORIM, Francisco Carlos Tavares; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079The construction industry provides occupational hazards to workers at construction sites. Despite the mandatory use of personal protective equipment (PPE), noise is one of the occupational hazards that persist as one of the most damaging to workers. The causes may be inherent in the control, but also by the inappropriate choice of methods of hearing protector implantation as an individual control measure. This work aims to analyze the efficiency of hearing protectors, taking into account the octave band spectrum at the sound pressure levels of the main equipment used in the civil construction sector in the city of Manaus.Item Acesso aberto (Open Access) Avaliação da qualidade do Mapará (Hypophthalmus spp.) estocado entre camadas de gelo provenientes dos mercados de pescados de Santarém – PA(Universidade Federal do Pará, 2021-08-09) CARDOSO, Renata Lima Sabá; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079Maintaining the good quality of fish is essential for consumer health and for strengthening the fish production chain. One of the main ways to maintain this quality is through the use of ice for fish storage. Thus, this research aimed to identify, through sensory, microbiological and chemical analyzes (H2S, ammonia and pH tests) factors that offered variation in the shelf life of the Mapará (Hypophtalmus spp.) ice layer storage process. Two collections were carried out at the Mercado do Pescado fair in Santarém-PA: experiment 1, with 143 fish and experiment 2, with 81 fish. For the analyses, two fish were removed for sensory evaluation, two for pH evaluation, one fish for ammonia test, one for the H2S Eber test and one fish for microbiological analysis. The results obtained in the sensory analysis indicated that the fish rejection point occurred between the 17th and 20th day. In experiments 1 and 2, the pH values in fish meat were above 6.5, that is, outside the limit established by law. In the Éber test for H2S, there were positive results from the 11th day. The Éber test for ammonia showed a positive value from the 14th day on. In the microbiological analysis, NMP/g values of <1.8 to 79x104 (NMP/g) were found for thermotolerant coliforms and from 11 to >1,600 (NMP/g) for total coliforms. Ice storage for Hypophthalmus spp. proved ineffective for long periods. The result allows us to infer that monitoring, research and continuous awareness of good fishing practices and post-harvest fish management are necessary.Item Acesso aberto (Open Access) Estudo da viabilidade de implantação de técnica de reaproveitamento dos resíduos do frigorífico Frigopeixe em Tefé-AM(Universidade Federal do Pará, 2019-05-06) CAXEIXA, Luiz Augusto Reis; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079The 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.Item Acesso aberto (Open Access) Gestão estratégica na manutenção de facility da indústria do varejo(Universidade Federal do Pará, 2019-05-06) COSTA, Pedro Rocha da; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079The globalization of the Market as a whole causes impacts in all segments of the modern world, competitiveness among suppliers of products and services is the most relevante and generally what permeates it are the exponential advances in the áreas of technology and communication, without due follow-up in the force therefore, this study has as a premise to understand the impacto f this effect on the retail industry and the behavior of costs in the result, with investments in more modern equipment and strategic management of facility maintenance and people management, compare the efficiency and effectiveness of the before and afferwards, compare these results with other major retail centers.Item Acesso aberto (Open Access) O GNL como mecanismo de flexibilização no fornecimento de gás natural para geração termelétrica no Amazonas(Universidade Federal do Pará, 2020-09-14) PEREIRA, Salony Aquino; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079Convergence between the natural gas and electricity markets is increasing as a result of the increasing liberalization of the natural gas and electricity markets, as well as increasing environmental constraints, projections of global natural gas demand indicate strong growth, especially in the electricity generation segment. The transport of natural gas in its liquefied form, LNG (Liquefied Natural Gas), is an important agent for this convergence as well as for the increasing global integration of the natural gas and electricity markets. It is observed that there is a supply of natural gas to be used, but is currently poorly distributed in the Amazon. Considering that there is only one natural gas supplier to Amazonas and conditions are limited for both new business and high investment price, it is important to evaluate new alternatives for natural gas supply and LNG supply is an interesting alternative. The present study evaluates the feasibility of an alternative model based on the possibilities of LNG supply, acting as a mechanism to flexibilize the supply of natural gas and ensuring a better use of electricity generation capacity today installed in the Amazon.Item Acesso aberto (Open Access) Influência da sazonalidade da bacia do médio Solimões na produção de pescado capturado(Universidade Federal do Pará, 2019-05-06) SANTOS, Claudio de Oliveira; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079The present study aimed to investigate factors that influenced the seasonality of catching fish in the Middle Solimões region, in the municipality of Tefé, State of Amazonas, specifically regarding the landing system and level of the Solimões River, aiming to identify the factors that influence the quantity of fish in the municipality of Tefé. In this, we sought to verify and describe the main aspects of the fishing landing in this municipality, in relation to the means of transport and typification of the fish, along with their landing, in a Fish Refrigerator and the local Fair. 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.Item Acesso aberto (Open Access) Influência do PPRA (Programa de Prevenção de Riscos Ambientais) na indústria, visando a redução de acidentes do trabalho: Estudo de caso(Universidade Federal do Pará, 2020-02-11) SERIQUE, Augusto César Pinto; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079The 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.Item Acesso aberto (Open Access) Uso do layout industrial como ferramenta de melhoria no processo de fabricação de carteiras escolares(Universidade Federal do Pará, 2020-09-14) REIS, Gilmara Cruz dos; CUNHA, Edinaldo José de Sousa; http://lattes.cnpq.br/8714515962963079One of the most common problems encountered in the manufacturing process, is the inadequate layout. About 30% of production time is wasted on transporting materials and products. The cause of this waste are problems in the disposition of stock and machines in production, that is, in the factory layout. In this context, the production line based on the cellular layout has been a powerful ally, since the cells of this layout are able to improve the use of available space, without increasing costs due to major renovations or constructions. To prove such improvements, through the implementation of the cell layout, the PSL method (Systematic Layout Planning) was used, which follows steps such as: data collection, analysis of the necessary and available space and factory limitations. With these stages of knowledge and analysis of the factory, it becomes possible to discard layouts that do not fit the characteristics of the company, whether related to financial resources, available space and factory culture. After choosing the cell layout, the statistical data was evaluated using the Chi Square test, with that, it became possible to validate that the production became more efficient with the use of the cell layout. The result found was that with the implementation of the cell layout, there was an increase in the number of wallets produced and a reduction in the waste of materials. It was concluded that the industrial layout is an efficient tool for improving the production process of school desks, because with the implementation of an adequate layout it broughtx numerous benefits to the factory under study, such as: increased productivity, greater organization and flexibility in the processes.
