Item Loss of product (cryogenic liquid) for filling of cars - tanks: production of liquid(INSTITUTO DE TECNOLOGIA, 2015) TORRINHA, Andrea da Silva; OLIVEIRA, Maria Socorro Frutuoso de; GUEDES, Megue Pinheiro; LEITE, Jandecy Cabral; José Antônio da Silva SouzaThe paper analyzes the loss of cryogenic liquids (oxygen and nitrogen) during the filling of tank cars, a critical stage in the transportation of these gases. Losses occur due to heat exchanges causing vaporization, internal pressure increase in tanks, and inadequate pump handling. Using field questionnaires, operational data, and literature review, the study suggests improvements such as better thermal insulation and operator training, emphasizing the economic and environmental impacts of such waste.Item Comparação do Impacto Ambiental duma Usina Elétrica quando Utiliza Motores de Óleo Combustível Pesado e quando Utiliza Motores a Gás(INSTITUTO DE TECNOLOGIA, 2013) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de Souza; MIGUEL, Paulo Augusto Cauchick; RODRIGUEZ, Jorge Laureano Moya; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesThe study compares the environmental impact of a power plant in the Brazilian Amazon when using heavy fuel oil (HFO) engines and natural gas engines. It analyzes emissions of pollutants such as CO, CO₂, NOx, SOx, and particulate matter, noting that gas engines emit less NOx and SOx but more CO and CO₂ per unit of power supplied.Item Diagnóstico de los factores microestructurales en el proceso de soldadura MIG/MAG que causan averías en los transformadores: estudio de caso(INSTITUTO DE TECNOLOGIA, 2012) LOPES, Raimundo Valdan Pereira; COSTA, Otávio Fernandes Limada; FUJIYAMA, Roberto Tetsuo; PINTO, Vagner Barroso; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesThe study examined microstructural factors in the MIG/MAG welding process of 3 mm and 4 mm industrial steel, leading to failures in 500 KVA power transformers. Charpy-V impact tests and microstructural analysis were conducted to correlate microstructure with impact toughness. Results revealed impurities in the weld pool, affecting weld quality and causing leaks of insulating oil.Item Desenvolvimento de um Modelo Matemático para a Avaliação da Eficiência da Combustão em Usinas Termoelétricas Operando com Gás e Alternando com Diesel(INSTITUTO DE TECNOLOGIA, 2015) AZEVEDO, Manoel S. Santos; LEITE, Jandecy Cabral; CARVAJAL, Tirso Lorenzo Reyes; RODRIGUEZ, Jorge Laureano Moya; RICO, Iván Leandro Rodriguez; DÍAZ, Pablo Romélio Roque; GOMES, Paulo Cezar Rocha.; Prof Dr. Walter Barra JuniorThe article presents a mathematical model developed to evaluate combustion efficiency in thermoelectric power plants operating with natural gas (NG) and alternating with diesel (HFO). The study was conducted in a plant transitioning to dual-fuel use, aiming to optimize energy efficiency and reduce pollutant emissions. The model covers stoichiometric, thermodynamic, and kinetic aspects of combustion, implemented in software for real-time analysis. Results demonstrated the model's feasibility in predicting engine performance and optimizing specific fuel consumption, with practical applications in plant operation.Item O uso de ensaios mecânicos para avaliação do produto canote do garfo(INSTITUTO DE TECNOLOGIA, 2010) SANTOS, Ruy Sidney Nascimento dos; FARIA, Marlene Araújo de; LEITE, Jandecy Cabral; MAGALHÃES, Edilson MarquesThe study focuses on technological innovation in the industrial sector, using mechanical tests and computational simulations to evaluate the bicycle seatpost fork product. Impact and drop tests were conducted according to technical standards (NBR 14714:2001), with results showing 100% approval. Tools such as CAD, CAM, and CAE were essential to ensure product quality and durability.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.
