Item Matrix polyester composite strengthened by munguba fiber (Pseudobombax munguba) Amazon(INSTITUTO DE TECNOLOGIA, 2015) LOPES, Raimundo V. P.; LEITE, Jandecy C.; FUJIYAMA, Roberto Tetsuo; AFONSO, Marcus R. B.; HERMENEGILDO, Eleodoro R.; MAGALHÃES, Edilson MarquesThe diversity of Amazon flora supports the development of new polymeric composites. This article evaluates the mechanical properties of polyester composites reinforced with short and continuous munguba fibers (Pseudobombax munguba). Tensile tests were conducted for fibers of different lengths (5, 10, and 15 mm) and continuous aligned fibers. Results indicated increased tensile strength with fiber length and superior mechanical performance with aligned continuous fibers.Item Photovoltaic Generation System Applied in Isolated Communities in the Amazon(INSTITUTO DE TECNOLOGIA, 2015) CABRAL, Rômulo Pereira; PINHEIRO, Marcos Cesar Alves; LEITE, Jandecy Cabral; Bruno Marques ViegasThe study examines the application of photovoltaic systems in isolated communities in the Amazon, emphasizing technical feasibility and socioeconomic and environmental benefits. Drawing on data from the "Light for All" project, it demonstrates that solar energy is a sustainable alternative for remote regions, lowering fossil fuel costs and fostering local development.Item Gestão Ambiental dos Empreendimentos Voltados ao Mercado Estético/Cosmético na Área Urbana de Manaus-AM(INSTITUTO DE TECNOLOGIA, 2014) TEIXEIRA, Lúcia Helena de Oliveira Leão; ALVES, Rui Guilherme Cavaleiro de Macêdo; Prof Dr. Walter Barra JuniorThe study analyzed the environmental aspects and impacts generated by aesthetic/cosmetic market enterprises in the urban area of Manaus, proposing environmental management practices to mitigate these impacts. Action research was conducted in small and medium-sized beauty salons, identifying issues such as excessive water consumption, energy inefficiency, generation of solid waste, and liquid effluents. The results emphasized the need for measures like selective waste collection, effluent control, and environmental education to promote sustainable practices in the sector.Item O Potencial de Captação e Abastecimento de Água Pluvial na Comunidade Vila de Lindóia – Município de Itacoatiara/AM(INSTITUTO DE TECNOLOGIA, 2015) SILVA, Marcos Maurício Costa da; MENDES, Ronaldo Lopes Rodrigues; NETO, João Augusto Pereira; LIMA, Aline Maria Meiguins de; Jandecy Cabral Leite"This article assesses the potential for rainwater harvesting for domestic use in the Vila de Lindóia community, Itacoatiara/AM. Fifteen residences were analyzed, considering roof areas, historical rainfall data, and residents' willingness to adopt the system. Results indicate that an area of 23.02 m² per person is sufficient to fully utilize rainwater, with the first flush discarded to ensure quality. The study concludes that implementing this system is feasible and can reduce reliance on traditional water sources, promoting water sustainability in the region."Item Advantages of applying composite material to replace metal alloys in aviation(INSTITUTO DE TECNOLOGIA, 2015) BARROS, Marcelo André Santiago; FUJIYAMA, Roberto Tetsuo; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesComposite materials were used by early agricultural societies and their adoption has been driven by military technological needs. High fuel costs and strict environmental regulations have increased the demand for this technology in the civil sector. This article presents the application advantages of composites in aircraft structures, especially regarding weight reduction, lower operational costs, and environmental, social, and economic impacts. The research includes literature review, experimental studies, and comparisons with traditional metal alloys.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.
