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 Logística Reversa de Pós-Consumo de Bateria de Celular(INSTITUTO DE TECNOLOGIA, 2012) SILVA, Carlos Américo de Souza; LEITE, Jandecy Cabral; VIEIRA, Kellen Bicho; MAGALHÃES, Edilson MarquesThis study examines reverse logistics as a tool for sustainable development, focusing on the proper disposal of mobile phone batteries, which contain heavy metals harmful to the environment. The research analyzed manufacturers, mobile operators, and consumers in the Manaus Industrial Pole (PIM), identifying challenges such as low consumer participation in the return process, despite the availability of return channels. The results emphasize the need for awareness campaigns and better-structured reverse channels to reduce improper disposal and promote recycling.Item Estudo dos Calços Infláveis de Filmes de Polietileno (PE) como substitutos dos Calços de Poliestireno (EPS) utilizados hoje nas Embalagens de Produtos Eletroeletrônicos(INSTITUTO DE TECNOLOGIA, 2010) OLIVEIRA, Macêdo Santos de; SILVA, José Antônio S.; LOPES, Antônio Dimael de Almeida; MONTEIRO, Alberto de Castro; DELON, José Alain; Prof Dr. Walter Barra Junior"This ongoing research involves a study using various types of nationally produced polyethylene (PE) films with different thicknesses to be applied as air cushions for protective padding in electronic product packaging. The aim is to replace the commonly used expanded polystyrene (EPS) padding with inflatable PE padding, which offers advantages such as lower cost, efficiency, low manufacturing cost, excellent mechanical performance, and full recyclability. The study compares the two types of padding in terms of logistics, storage, cost, and production efficiency."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 Modelo de Certificação Ambiental em Processos e Produtos Eletrônicos(INSTITUTO DE TECNOLOGIA, 2012) SILVA, Carlos Américo de Souza; LEITE, Jandecy Cabral; PALADINI, Edson Pacheco; VIEIRA, Kellen Bicho; Edinaldo José de Sousa CunhaThe article presents an environmental certification model (Green Partner) for electronic processes and products, aiming to eliminate or control hazardous substances such as heavy metals (cadmium, lead, chromium, and mercury). Based on Sony's SS-00259 standard, the study demonstrates the model's application in a company from the Manaus Industrial Hub, highlighting the integration of management systems (ISO 9001, ISO 14001, OHSAS 18001) and the competitive and sustainable benefits of certification.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 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.
