Among these features is photocatalysis, which imparts self-cleaning and antimicrobial properties to materials, making them fundamental for reducing pollutants present in liquid effluents and representing an interesting alternative to the emerging environmental crisis—water pollution. In this specific context, the research focuses on developing a photocatalytic mortar using powdered magmatic rock (gray andorinha granite) as a partial substitute for natural sand. This residue acts as a precursor to photocatalytic properties, containing titanium dioxide and iron oxide, which have the potential to facilitate photocatalysis. Test specimens were produced with partial substitutions of natural sand by crushed residue in proportions of 15%, 30%, and 30% combined with the addition of ZnO-NP nanoparticles (0.33%) to intensify photocatalytic activity. A control sample was prepared without the addition of residue or ZnO-NP. The photocatalytic efficiency of the developed mortars was tested by degrading methylene blue in mortar plates immersed in an aqueous solution and exposed to sunlight for four hours. The results showed that samples containing the residue exhibited superior photocatalytic performance compared to the control, demonstrating the efficacy of the residue in dye degradation. The sample RR-30/NP-1 showed one of the best photocatalytic performances, with efficiency surpassing that of the control (81.37%), degrading 88.68% of the methylene blue dye. Additionally, the use of powdered magmatic rock significantly increased the compressive strength of the mortar. After 56 days of curing, the RR-15, RR-30, and RR-30/NP-1 samples exceeded the reference samples, whose strengths were: 76.61 MPa for the control, 88.22 MPa for the RR-15 sample, 80.59 MPa for the RR-30 sample, and 102.15 MPa for the RR-30/NP-1 sample, highlighting their superiority over the control. Therefore, the developed material exhibits characteristics that promote sustainability by providing environmental advantages through its application in effluent treatment and the reuse of industrial residues, reducing the extraction of natural resources. In this way, this work aligns with three objectives outlined in the United Nations' 2030 Agenda: “Industry, Innovation, and Infrastructure,” “Responsible Consumption and Production,” and “Clean Water and Sanitation.” Instituição: Universidade do Oeste Paulista Tipo do documento: Dissertação Wed, 14 May 2025 00:00:00 GMT http://bdtd.unoeste.br:8080/jspui/handle/jspui/1752 2025-05-14T00:00:00Z http://bdtd.unoeste.br:8080/jspui/handle/jspui/1743 Título: Avaliação do impacto socioeconômico da cultura do Baru em municípios com comunidades em situação vulnerável Autor: Reis, Jucimar Alves dos Primeiro orientador: Osco , Lucas Prado Abstract: Baru (Dipteryx alata), a native species of the Brazilian cerrado, has emerged as a significant economic alternative for low-income communities in the northwest region of Minas Gerais. Despite structural and market challenges, the extractivism of baru has adopted sustainable practices that contribute to the preservation of the cerrado's biodiversity while providing an essential source of income for small farmers and local extractivists. This study aims to assess the socioeconomic impact of this activity in low-income municipalities of the northwest mesoregion of Minas Gerais, focusing on its relevance to family farming and regional development. The research provides a detailed analysis of extractivism practices, commercialization, and sustainable management, combining socioeconomic and environmental data obtained through documentary research, interviews, and geospatial analysis. The findings reveal the potential of baru extractivism to boost the local economy sustainably while proposing measures to optimize existing practices, minimize environmental impacts, and expand the benefits for the involved communities. The recommendations aim to strengthen cooperatives, add value to baru-derived products, and expand commercialization networks.

Environmental education is a transdisciplinary field that seeks to promote a critical-dialogical view and understanding of environmental issues, as well as to develop skills and attitudes that lead to responsible and sustainable actions in relation to the environment, which makes Curricular Greening a transformative element for the relationship between human beings and the environment. In this context, the present research aims to verify how the proposal of Curricular Greening is developed in the Medicine course at the Presidente Prudente-SP campus of the University of Western São Paulo (Unoeste), analyzing how environmental issues are incorporated into this course. Thus, the study examines how the environmental question has been incorporated into the Course Pedagogical Project. Furthermore, it analyzes how the Curricular Matrices present environmental concerns by verifying the presence of greening indicators in the Course Syllabi, based on the Network of Curricular Greening of Higher Education. The research has a quantitative nature, beginning with an exploratory review of the literature on Curricular Greening in Medicine courses in Brazil. Subsequently, data was collected through a documentary analysis of the Course Pedagogical Project and the syllabi of the disciplines of the Unoeste Medicine course in Presidente Prudente-SP. The results show that Curricular Greening indicators are present in 75.7% of the courses. Among the disciplines investigated, it is observed that those in the fields of ethics, social interactions, and public health are more integrated with the greening indicators. On the other hand, the technical disciplines, to date, do not meet the same indicators. Thus, it is verified that the technical disciplines of the medicine course present an interesting opportunity for Curricular Greening to be expanded in the investigated course. Regarding the disciplines more closely related to social issues and marked by the indicators, it is noted that the course documents show a concern with greening derived from the analysis of socio-environmental problems and their impact on the analyzed context.

The research sought to identify, analyze, and propose solutions to the environmental problems affecting water quality, ecosystem integrity, and the stability of the permanent preservation areas (APPs) associated with the Cortado Stream. The adopted methodology included an approach that combined literature review, field study, and the application of the Adapted Leopold Matrix. Initially, a detailed literature review was conducted to understand the main challenges faced by urbanized areas involving water bodies, focusing on erosion processes, sedimentation, and water pollution. Subsequently, monitoring campaigns were carried out along the Cortado Stream during different seasonal periods (dry and rainy) to collect data on water quality, including physicochemical parameters such as pH, biochemical oxygen demand (BOD), total nitrogen, total phosphorus, turbidity, among others. The analysis of the collected data revealed that the areas near the stream experience significant pressures due to uncontrolled urbanization, which contributed to increased soil impermeability and the pollutant load of stormwater. During the rainy season, a higher concentration of pollutants was observed, resulting in higher turbidity levels and the presence of thermotolerant coliforms, suggesting that stormwater acts as a significant contamination vector. Additionally, accelerated erosion and sediment deposition processes were identified, altering the stream's morphology and threatening the stability of the slopes. To systematically assess the impacts, the Adapted Leopold Matrix was applied, which allowed for the classification of impacts in terms of magnitude and importance. The results indicated that the main impacts include the deposition of solid waste, the absence of adequate stormwater dissipators, and evidence of fires, all contributing to the environmental degradation of the Conservation Unit. The analysis showed that most impacts are of high magnitude, requiring urgent interventions to prevent the worsening of environmental conditions. As part of the mitigation strategies, this study suggests the implementation of bioengineering techniques to stabilize slopes and improve urban drainage infrastructure. The construction of a retention basin, which is already in the implementation phase, is a necessary measure to buffer the initial pollution from precipitation and prevent the transport of sediments and pollutants to the stream. In conclusion, this study provides a detailed understanding of the environmental impacts in the Cortado Stream Ecological Park area and proposes practical solutions for the recovery and preservation of this urban ecosystem. The application of the Adapted Leopold Matrix has proven to be an effective tool for identifying and prioritizing impacts to be mitigated, providing a solid basis for the formulation of public policies and conservation actions aimed at the sustainability of the Conservation Unit and the improvement of the quality of life in the Taguatinga region.
