Desenvolvimento de método para obtenção de trilhas condutivas com grafeno por esfoliação em fase líquida aplicadas à eletrônica impressa na Indústria 4.0
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) VALADÃO, Suélem Cabral; LEITE, Jandecy Cabral
This study presents the development and characterization of conductive tracks based on graphene obtained via liquid-phase exfoliation (LPE), applied to printed circuit boards (PCBs) on FR4 substrates. Graphene synthesis was carried out by dispersing graphite flakes in a surfactant-assisted solvent, followed by ultrasonic exfoliation for 30 minutes. The resulting material was characterized using XRD, SEM, and Raman spectroscopy, confirming the presence of multilayer graphene with moderate structural defects. Conductive inks were formulated with different proportions of Jutaicica resin, a natural Amazonian binder, achieving good adhesion to the substrate. Tests indicated average track thickness of ~72 µm and electrical conductivity of 0.75 and 0.91 (Ω.cm)-¹ for inks 1 and 2, respectively. The findings demonstrate the potential of LPE graphene combined with Amazonian biodiversity inputs for the formulation of functional and sustainable conductive inks, aligned with sustainability principles and Industry 4.0.
Desenvolvimento de um sistema de monitoramento inteligente para determinação do ponto ótimo para o abate de animais de produção utilizando visão computacional e inteligência artificia
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) FARIAS, Djalma Farias e; NASCIMENTO, Manoel Henrique Reis
Beef cattle production faces challenges in accurately identifying the ideal slaughter time for Nelore cattle, affecting yield and animal welfare. Traditional monitoring methods, such as manual weighing and visual inspection, may compromise meat quality and increase costs. This study developed an intelligent monitoring system using computer vision and artificial intelligence to determine the optimal slaughter moment for Nelore cattle. The system applies deep learning algorithms and video cameras to analyze animals in real time, considering productive and morphological parameters. A cost-benefit analysis was performed based on hardware, software, and operational returns. Results showed increased productivity, improved slaughter precision, and an estimated 268.42% ROI over five years, demonstrating the technical and economic feasibility of AI-based livestock monitoring.
Proposta de implantação da tributação ambiental como ferramenta de incentivo na conservação e desenvolvimento sustentável: um estudo de caso sobre a potencialidade do IPTU Verde na cidade de Manaus
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) MONTEIRO, Ciro Allister Reis; LEITE, Jandecy Cabral; Almeida, Luiz Fernando Correia de
This dissertation analyzes the application of environmental taxation as an incentive tool for conservation and sustainable development, based on a case study of Bill No. 248/2013, known as the Green IPTU, in Manaus, Brazil. The study aims to assess the importance of environmental tax benefits—particularly partial tax exemptions—as mechanisms for environmental preservation and maintenance. This qualitative and quantitative research combines bibliographical review, document analysis, and case study methodology. The findings emphasize the relevance of the “polluter pays” principle and sustainable fiscal policies as strategic alternatives to urban environmental degradation, underscoring the importance of local public policies for sustainability and environmental responsibility.
Análise comparativa da ozonização e outros métodos de desinfecção na produção de água potável
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) FERREIRA, Arthur Joaquim de Araújo; SILVA, Simone da
This dissertation presents a comparative analysis between ozonation, associated with microbubble application, and conventional disinfection methods used in drinking water production. The study was conducted at the São Roque Water Collection Network in Itajaí, Santa Catarina, aiming to evaluate the technical-operational efficiency of ozone use compared to traditional technologies in the sanitation sector. The research, of mixed and experimental nature, combined bibliographical analysis, laboratory experimentation, and a case study. Results showed that the microbubble ozonation system achieved superior performance in removing pathogenic microorganisms and chemical contaminants, establishing itself as an effective and sustainable technological alternative for water treatment.
Análise técnica da manutenção preventiva em subestações: foco em transformadores, disjuntores e chaves seccionadoras
(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) PIMENTEL, Eduardo Fernandes; MARINELLI FILHO, Nelson
This dissertation presents a technical analysis of preventive maintenance in substations, focusing on transformers, circuit breakers, and disconnect switches. Substations, essential for power transmission and distribution, are exposed to continuous operation under adverse conditions, leading to potential wear and failures. The study, of an applied and technical nature, is based on ABNT standards, manufacturers' manuals, and best practices from the electrical sector. The results demonstrate that preventive maintenance reduces failures, increases reliability, and extends equipment lifespan, serving as a strategic investment for the safety and efficiency of substations.
