Item Análise para diminuição das perdas no processo de Geração de Energia Elétrica da UHE - Balbina.(Instituto de Tecnologia, 2010) ARTEGA, Roland Céspedes; BLANCO, Claudio José Cavalcante; LEITE, Jandecy Cabral.; QUARESMA, João Nazareno NonatoThis article presents an analysis to standardize the performance of the turbines at the Balbina Hydroelectric Plant, located in Amazonas, Brazil, focusing on reducing head losses caused by the obstruction of water intake screens by wood from the flooded forest. The study proposes the installation of a containment net to prevent debris accumulation, minimizing unplanned shutdowns and associated costs with replacement thermal generation.Item Aplicação de Óleo Vegetal de Andiroba (Carapa guianensis) como Fluido Dielétrico em Transformadores de Potência(Instituto de Tecnologia, 2013) PINTO, Vagner Barroso; LEITE, Jandecy Cabral; FUJIYAMA, Roberto Tetsuo; LOPES, Raimundo Valdan Pereira; BRITO JUNIOR, Jorge Almeida; QUARESMA, João Nazareno NonatoThe study investigated the use of andiroba vegetable oil (Carapa guianensis) as an alternative dielectric fluid in power transformers, aiming to replace petroleum-derived mineral oils. Physical-chemical and electrical properties of the oil were evaluated and compared with technical standards (ABNT NBR 15422) and commercial oils (BIOTEMP®, ENVIROTEMP® FR3™). Results indicated that andiroba oil has suitable viscosity and density, is biodegradable, and non-corrosive. However, specific treatments are required to adjust parameters such as water content and dielectric strength. It was concluded that andiroba oil is a viable candidate for transformer applications, leveraging renewable resources from the Amazon.Item Avaliação da Variação das Frações Mássicas das Fibras nas Propriedades Mecânicas do Compósito Poliéster Reforçado por Fibras de Sisal(Instituto de Tecnologia, 2013) EL BANNA, Wassim R.; COSTA, Delbson S. da; GILDO, Camila C. R.; LOPES, Raimundo Valdan P.; PINTO, Wagner B.; LEITE, Jandecy Cabral; FUJIYAMA, Roberto T.; QUARESMA, João Nazareno NonatoThe study evaluated the influence of sisal fiber mass fractions (1.41% to 9.41%) on the mechanical properties of polyester matrix composites. Specimens were fabricated by manual molding and subjected to tensile tests according to ASTM D 638. Results showed that the 5.41% mass fraction achieved the highest tensile strength (22.23 MPa), outperforming other natural fibers. Beyond this fraction, strength decreased due to fiber-matrix interface saturation. The manufacturing method proved viable for producing sustainable and low-cost materials.Item SISTEMA FOTOVOLTAICO NO AEROPORTO INTERNACIONAL DE MANAUS: Análise da Viabilidade Técnica, Econômica e Ambiental de Implantação Usando Simulação Computacional(Instituto de Tecnologia, 2018) Carlos Gomes Fontinelle; LEITE, Jandecy CabralThe dissertation analyzes the technical, economic and environmental feasibility of implementing a photovoltaic system at the Manaus International Airport, using computer simulation. The study considers factors such as solar incidence, installation costs, financial return and environmental impacts, demonstrating the potential of solar energy to reduce operating costs and greenhouse gas emissions. The results indicate that the adoption of photovoltaic technology is a sustainable and economically viable alternative for the airport's energy matrix, contributing to energy efficiency and environmental preservation.Item Captação, Armazenamento e Utilização de Águas Pluviais com o Mínimo de Interferência Manual: Estudo de Caso em um Instituto Federal(Instituto de Tecnologia, 2018) PALHETA, Pedro Ivan das Graças; LEITE, Jandecy CabralThe study proposes an automated system for capturing, storing, and utilizing rainwater at the Federal Institute of Education, Science, and Technology of Amazonas (IFAM) – Manaus Industrial District Campus, aiming to reduce potable water consumption. The system uses photovoltaic panels to power sensors and actuators, ensuring autonomous operation. The reservoir was sized based on historical rainfall data, and preliminary results include the installation of reservoirs and process automation. The captured water is intended for non-potable uses, such as toilet flushing and cleaning, contributing to environmental and economic sustainability.Item Estudo e Avaliação de Máquinas Integradas e Automatizadas para Extração de Óleo Vegetal(Instituto de Tecnologia, 2017) REIS, Ilmar Duarte dos; BRAGA, EduardoThis dissertation proposes the development of an innovative machine, composed of integrated and automated modules, for extracting vegetable oil from seeds such as andiroba. The aim is to improve oil quality, reduce extraction time, eliminate slave labor, and increase productivity. The study covers processes from seed selection to centrifugation, including automated washing, crushing, and transportation, with temperature and humidity control. The proposal seeks to generate employment and income for rural communities while reducing contamination of the final product.Item Viabilidade da Aplicação de Resíduos da Cerâmica Branca Oriundos da Cidade de Manaus para Produção de Argamassas(Instituto de Tecnologia, 2017) MELO, José Roberto de Souza; MAGALHÃES, EdilsonThis study proposes the use of white ceramic waste (RCB), generated in the city of Manaus, as a pozzolanic material in mortar production. X-ray fluorescence and diffraction analyses identified the presence of silicon, aluminum, iron, and sodium oxides in proportions that comply with ABNT NBR 12653/1992 standards. Five mixtures with varying proportions of RCB, sand, and cement were tested and evaluated for porosity, water absorption, specific mass, and compressive strength. The results indicated that the produced mortars can be classified as Class PI and P2, according to ABNT NBR 13279, demonstrating the technical feasibility of replacing up to 50% of natural aggregate with RCB, reducing costs and environmental impact.Item Diminuição dos resíduos orgânicos gerados por uma Unidade de Alimentação e Nutrição do Polo Industrial de Manaus: Efeitos de uma campanha de sensibilização(Instituto de Tecnologia, 2017) GOMIDES, Renata Campos; BRASIL, Davi do Socorro BarrosThe habit of wasting food is rooted in the national culture, a fact that adds to the reduction of the nutritional proportions offered to thousands of families, becoming more relevant in less affluent populations. This study aimed to describe the relationship between the menus offered and the organic waste generated by a UAN of the Industrial Pole of Manaus, as well as to raise awareness among employees about the importance of reducing organic waste. The results showed that as the rest of the intake decreased, the number of cards distributed increased, indicating greater employee contribution to waste reduction. It was concluded that the type of menu and the way meals are served influence waste production, and further studies on the topic are needed.Item Análise de Mercado e Proposta de Desenvolvimento de Processo Industrial na Produção de Polpa de Tucumã em Manaus-AM(Instituto de Tecnologia, 2017) MONTEIRO, Juliann Huxley de Souza; OLIVEIRA, Kleber BittencourtThe study proposes the implementation of a semi-automated industrial process for the production of tucumã pulp in Manaus, aiming to improve product quality and reduce waste. The research includes market analysis, diagnosis of the current process, and evaluation of technical-economic feasibility, highlighting the potential use of solid waste for purposes such as animal feed, biodiesel, and crafts.Item Análise do Processo de Descarte e Reciclagem de Vidro em uma Distribuidora de Bebidas da Cidade de Manaus, Estado do Amazonas(Instituto de Tecnologia, 2017) SILVA, Fabiane Amaral de Albuquerque; LIMA, Marcelo OliveiraPublic policies around the world are being developed by organizations, such as the United Nations (UN), to preserve the environment and raise awareness about the importance of recycling. This study analyzed the process of glass disposal and recycling in a beverage distributor in Manaus, Amazonas, using parameters similar to those in the report 'Study for the Development of an Integrated Solution Regarding the Management of Industrial Waste in the Industrial Pole of Manaus'. The results showed that the selected company sends 78% of discarded glass for recycling, while 18% is collected by the municipality and 4% goes to landfills. It was concluded that the company operates within environmental standards, with a concern to avoid environmental contamination, and improvements were suggested to optimize the recycling process.
