The present article describes the development of a grain mill prototype with an integrated safety system, designed in compliance with Brazilian Regulatory Standard No. 12 (NR-12), aiming to ensure the operational efficiency and the physical safety of operators. The research intended to develop and analyze an automated, safe and ergonomic equipment. Methodologically, the study was structured in four stages: the design of the mechanic and electric project, the implementation of the automat...

This study analyzes the feasibility and strategies for implementing an electric vehicle charging infrastructure along the BR-040 highway, in the section between Belo Horizonte and Rio de Janeiro. The research was developed through bibliographic review, analysis of secondary data, and mapping of existing charging stations in order to identify gaps and opportunities for network expansion. It was observed that, although the total number of charging points in Brazil has increased significantly in...

Law No. 14,300/2022 introduced a new regulatory framework for distributed photovoltaic generation in Brazil, leading to changes in the compensation and tariff structure applied to injected and compensated energy. These modifications directly affect the economic performance of photovoltaic systems connected to the distribution grid. This study aims to analyze the impacts of this legislation on electricity costs for Group A4 consumers who use distributed generation. A quantitative methodology i...

This study presents the importance of strategic planning in industrial maintenance, highlighting its direct influence on the reliability, efficiency, and safety of production processes. The proper operation and planned maintenance of industrial equipment are essential to ensure production continuity and reduce operational costs. The research was developed through a qualitative and descriptive approach, based on a medium to large-sized steel plant located in the state of Minas Gerais, Brazil.T...

This work aims to highlight the importance of Regulatory Standard No. 12 (NR-12) for the protection of workers involved in activities with machinery and equipment. The research discusses how the application of regulatory requirements is essential for reducing accidents and mitigating risks, and emphasizes the use of the Hazard Rating Number (HRN) calculation method as a crucial quantitative tool for this analysis. This study discusses the role of industrial automation as a strategic supp...

This study presents a comparative analysis of the energy efficiency of two HVAC systems: the VRF (Variable Refrigerant Flow) system and the Water-Cooled Chiller system, both designed to meet the thermal load of a 375 TR commercial building. The methodology included computational modeling, thermodynamic calculations using the EES software, and the evaluation of performance indicators such as COP, EER, energy consumption, and operating costs. Results showed that the Chiller achieved a sup...

Breast cancer is one of the leading causes of female mortality worldwide, characterized by the disordered proliferation of cells in the mammary glands, often resulting in metastases. Its treatment includes strategies such as surgery, chemotherapy, radiotherapy and targeted therapies, with mastectomy standing out, although this technique is associated with complications such as lymphedema and chronic pain. Methods such as manual lymphatic drainage (MLD) and kinesiotherapy have shown effi...

This study examines the human rights violations faced by incarcerated women who are mothers and in the postpartum period in Brazil. The research employed a systematic literature review, drawing on bibliographic and documentary sources, complemented by an analysis of national and international legal frameworks and a case study. The findings reveal substantial challenges to the protection of these women’s rights, including inadequate access to healthcare, the erosion of the mother– child ...

Medical error is an interdisciplinary topic that's particularly relevant in the field of Law. This study's general objective was to discuss the limits of criminal liability for medical error in the negligent modality, specifically due to imprudence and negligence. Aspects related to medical errors were discussed, as well as the analytical concept of crime and the actual punishment suffered by these professionals when committing such negligent crimes. The methodology was explanatory and q...
