    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."

    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 Marques
    Composite 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.

    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 Nonato
    The 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.

    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 Nonato
    The 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.
