Other Inspeções em veículos GNV: um levantamento de itens não conformes detectados em um organismo de inspeção(2025-12-10) COSTA, Francisco Levy LimaNatural gas is an abundant energy source in Brazil. Its use varies across different applications, one of which is in automotive vehicles, where they are converted to run on CNG (Compressed Natural Gas) to achieve greater economy and performance, in addition to polluting less. The installation of a CNG kit in a vehicle makes vehicle inspection mandatory, an essential condition for the vehicle's legalization. According to current legislation, this inspection is a mandatory requirement immediately after the vehicle conversion and must be repeated periodically, with annual validity. This study identifies the items of CNG kits installed in automobiles that showed the highest number of non-conformities during vehicle inspections over a 6-month period at an accredited Inspection Body. This identification was carried out through the application of quality tools, such as Pareto Analysis and FMEA, thereby determining the priority criteria for potential improvements.Other Aplicação da NR-11 em um armazém logístico: análise da segurança e da eficiência na movimentação e armazenagem de materiais com empilhadeiras(2025-12-10) SILVA, Hudson Matheus de SouzaBalancing safety and efficiency in material handling within logistics warehouses through the implementation of NR-11 represents a strategic challenge for organizations seeking to align productivity, legal compliance, and worker well-being. The main objective of this study is to evaluate the implementation of regulatory standards in logistics operations involving forklifts, also considering the operators’ perceptions of daily material handling and storage activities. In this context, the study aims to identify the safety practices adopted and analyze opportunities for improvement, with the goal of optimizing transport and stacking processes while ensuring operational efficiency without compromising workers’ physical integrity. Through a semi-structured methodology, the research seeks to analyze response patterns from workers operating in sectors with a high flow of machinery used for the transport and storage of materials within an industrial environment. This approach enables a deeper understanding of different perspectives on the same topic, particularly from those with direct experience in forklift operation, contributing to a more comprehensive and grounded analysis of safety and efficiency in logistics activities.Other A importância da manutenção em sistemas hidráulicos(2026-03-10) Brasil, Jhonatan EvangelistaWith the continuous industrial technological advancement, the implementation of preventive maintenance plans in hydraulic systems has become indispensable for mitigating catastrophic failures and optimizing operational performance.

Recently, sodium trititanate (Na2Ti3O7), an inorganic chemical compound, has received attention due to its effectiveness in ion exchange and catalytic properties. However, its application as an electrolyte in solid-state batteries is limited due to its low electrical conductivity. To overcome this limitation, lithium-doped Na2Ti3O7 nanoparticles were synthesized in different proportions, ranging from 0% to 5% by mass, using the microwave-assisted hydrothermal method. Samples were extensively characterized by XRD, 0%, 1% and 5% samples were also analyzed by DTA, Raman spectroscopy and complex impedance spectroscopy. Notably, the 5% lithium doped sample exhibited an electrical resistance approximately one order of magnitude lower than the undoped material. These promising results highlight the potential of doped sodium titanate as a viable component for high-performance solidstate batteries due to its enhanced structural and conductive properties.Artigo de Evento Padronização do planejamento e controle de manutenção através do pilar de manutenção profissional pertencente a metodologia WCM em uma empresa da linha branca do polo industrial de Manaus - AM(2024-08-22) Pereira, Wander Sousa; Pinto, Camila Costa; Maciel, Paulo Fernando Figueiredo; Fialho, Michaella Socorro Bruce; Oliveira Neto, Benjamim Batista deIn today's globalized scenario, pursuing excellence in maintenance management is crucial for companies to maintain their competitiveness in the international market. With the advent of Industry 4.0, the concept of World Class Manufacturing (WCM) emerges, focusing on waste elimination and continuous improvement in efficiency through technical and managerial pillars.
