    Aplicação de radioatividade na medicina nuclear
    (2026) Silva, Rosilainy Raquielle Santos da; Silva, Marina de Magalhães; Silva, Marina de Magalhães; Barbosa, Amaury Franklyn Benvindo; Cabral, Mirelle Márcio Santos
    This work analyzes the applications of radioactivity in Nuclear Medicine and Radiotherapy, addressing its historical evolution, physical foundations, diagnostic and therapeutic methods, as well as the principles of radiation protection.The study, qualitative in approach, exploratory in nature, and bibliographic in character, was based on scientific sources obtained from articles and databases such as Google Scholar, SciELO, and CAPES journals. It examines essential concepts of radioactivity, such as types of radiation and decay mechanisms, and discusses the technological development that enabled the emergence of functional imaging techniques. The research also describes the advancement of therapeutic methods, with emphasis on external beam radiotherapy, brachytherapy, and the use of specific isotopes such as iodine-131, highlighting their effectiveness in the treatment of neoplasms and thyroid diseases. The results show that ionizing radiation has become an indispensable tool for early diagnosis and clinical monitoring, contributing to greater therapeutic precision and increased patient survival. The study concludes that, despite the benefits, the use of radiation requires strict adherence to radiological protection standards due to the associated biological risks and highlights the need for investments in infrastructure and professional training to expand access to advanced technologies in Brazil.

    Controle de qualidade do açúcar cristal
    (2025) Ferreira, Daniel Douglas dos Santos; Cabral, Mirelle Márcio Santos; Cabral, Mirelle Márcio Santos; Barbosa, Amaury Franklyn Benvindo; Chaves, Taciana Carneiro
    Crystal sugar plays a central role in the Brazilian sugar-energy industry, requiring rigorous quality control to ensure purity, stability, and compliance with the standards demanded by the food, pharmaceutical, and export sectors. Considering that operational factors directly affect the physicochemical parameters of the product, this study analyzes how these indicators reflect the efficiency of the production process. The objective was to evaluate the importance of quality control and identify the influence of ICUMSA color, polarization, moisture content, ash content, reducing sugars, sulfite, and dextran on the final quality of crystal sugar. The methodology was based on a bibliographic review using scientific articles, technical standards, ICUMSA and MAPA documents, as well as the description of analytical methods used in the sugar industry, including spectrophotometry, polarimetry, calcination, oven drying, titration, and chromatography. The results demonstrated that ICUMSA color is directly influenced by clarification efficiency and thermal control; polarization reflects sucrose purity; moisture determines storage stability; ash content indicates mineral impurities; and reducing sugars increase due to thermal or microbiological sucrose degradation. It was also verified that sulfite residues depend on the rigor of chemical treatment during juice clarification, while dextran is associated with cane deterioration and negatively affects crystallization. It is concluded that quality control of crystal sugar is a strategic step in industrial management, enabling deviation detection, process optimization, and the assurance of a final product that meets national and international standards. The integration of laboratory analyses with modern technologies enhances operational efficiency and contributes to greater competitiveness within the sector.

    Da cana ao combustível: um estudo sobre o processo produtivo e a comercialização do etanol no Brasil
    (2025) Rodrigues, Emerson da Silva; Silva, Marina de Magalhães; Silva, Marina de Magalhães; Barbosa, Amaury Franklyn Benvindo; Cabral, Mirelle Márcio Santos
    Ethanol derived from sugarcane stands out as one of the most promising biofuels due to its versatility, efficiency, and technical, economic, and environmental viability. In this context, this study aims to analyze the production process of sugarcane ethanol, addressing its industrial stages, relevance in the energy matrix, and related commercial and environmental impacts. The research was conducted using a qualitative approach, with an exploratory and bibliographic character, based on scientific sources collected from books, articles, and academic databases such as Google Scholar, SciELO, and CAPES journals. The results demonstrate that sugarcane ethanol not only contributes to energy diversification but also consolidates itself as a sustainable alternative to fossil fuels, reinforcing Brazil’s role as a global leader in the production and commercialization of biofuels.

    Produção de açúcar refinado
    (2025) Santos, Vaniel Ferreira dos; Silva, Marina de Magalhães; Silva, Marina de Magalhães; Barbosa, Amaury Franklyn Benvindo; Cabral, Mirelle Márcio Santos
    Currently, Brazil leads the global sugar exports, historically establishing itself as a powerhouse in the sugar-energy sector since the colonial period. This study aims to contextualize the production of refined sugar from sugarcane, linking historical evolution, the Brazilian scenario, and industrial stages, in order to highlight how technological and control decisions impact product quality, yield, and cost. The process involves extraction, purification, crystallization, and refining, with rigorous monitoring of pH, color, granulometry, and moisture. The methodology used was qualitative, exploratory, and bibliographic, based on books, journals, and academic databases such as SciELO, Google Scholar, and CAPES. The study highlights the evolution of the Brazilian sector, quality control practices, integration with ethanol and energy production, and the importance of qualified professionals and automation technologies to ensure stability, productivity, and competitiveness of refined sugar. It was found that fine-tuning operational variables, supported by automation and laboratory monitoring, reduces losses, maintains compliance, and enhances competitiveness, creating opportunities for innovation and more sustainable production routines in the sector.
