Secagem como estratégia para redução de perdas no pós-colheita de frutas e hortaliças: uma revisão
(Universidade Federal de São Carlos, 2026-06-30) Pinheiro, Caroline; Consoli, Larissa; http://lattes.cnpq.br/0760277067023906
Fruits and vegetables are highly perishable due to the continuation of metabolic activity after harvest, particularly cellular respiration, combined with their high water content, factors that contribute to significant postharvest losses. In this context, drying stands out as an important preservation strategy by reducing water activity, increasing the commercial stability of foods, and extending their shelf life. This study aimed to conduct a literature review on the application of drying as a preservation technology to reduce postharvest losses in fruits and vegetables. The review addressed the principles of the drying process, heat and mass transfer mechanisms, drying kinetics, and the different drying techniques used in the food industry, including natural drying, tray drying, drum drying, spray drying, infrared drying, and freeze-drying. Scientific articles, books, dissertations, and theses retrieved from national and international databases were used to develop the study. In addition, case studies related to the different drying techniques were analyzed, highlighting the operating conditions, equipment used, and the main results observed for each process. The analysis demonstrated that the choice of drying technique and operating conditions directly influences the final product quality, stability, and preservation of bioactive compounds. Furthermore, these technologies showed great potential for the valorization of agro-industrial residues and the reduction of food waste. Therefore, drying is an important preservation tool, contributing to the reduction of postharvest losses and to the development of products with greater stability and extended shelf life.
Educação escolar indígena na comunidade de Querari: práticas pedagógicas e desafios no contexto de fronteira Brasil-Colômbia
(Universidade Federal de São Carlos, 2026-07-08) Lana, Franz Rodrigues; Franca, Gilberto Cunha; http://lattes.cnpq.br/0983946781650048; https://orcid.org/0000-0002-5637-2255; Kubeo
Indigenous school education constitutes an important instrument for the valorization of cultural identities, the preservation of traditional knowledge, and the guarantee of educational rights of Indigenous peoples. In this context, the present study aimed to analyze the pedagogical practices and challenges of Indigenous school education in the Querari community, belonging to the Kubeo people, located in the Alto Uaupés region, on the border between Brazil and Colombia. The research sought to understand how the educational practices developed at the Nossa Senhora da Imaculada Conceição Indigenous State School articulate traditional knowledge with school knowledge, considering the territorial, cultural, and social specificities of the community. Methodologically, this is a qualitative research with an exploratory and descriptive character, developed through bibliographic and documentary research. The theoretical framework was based on studies on Indigenous school education, interculturality, territoriality, pedagogical practices, and the sociocultural organization of Indigenous peoples in the Amazon, drawing on works by authors such as Gersem Baniwa, Clarice Cohn, Vera Maria Candau, Catherine Walsh, Rogério Haesbaert, Milton Santos, Diego Pedroso, and other researchers on the subject. The results showed that the Indigenous school plays an essential role in preserving the language, collective memory, and traditional knowledge of the Kubeo people, establishing itself as a space for strengthening cultural identity and building an intercultural education. Challenges were also identified related to geographic isolation, infrastructure limitations, difficulties in accessing public policies, and the need for greater appreciation of pedagogical practices grounded in traditional knowledge. It is concluded that Indigenous school education in Querari constitutes a space for cultural resistance, knowledge production, and territorial strengthening, contributing to the education of new generations without breaking with the values, culture, and identity of the Kubeo people.
Entre linhas de código e gênero: ciência de dados e experiências vividas na análise da discriminação de gênero na TI em Sorocaba
(Universidade Federal de São Carlos, 2026-05-25) Mercado, Cristiane Palomar; Ferro, Andrea Rodrigues; http://lattes.cnpq.br/3432809140419477; https://orcid.org/0000-0002-0145-8203; Leite, Kelen Christina; http://lattes.cnpq.br/0993995005511082; https://orcid.org/0000-0002-8590-1857; http://lattes.cnpq.br/6546422898817208; https://orcid.org/0000-0002-3095-1849; Silva, Vanda Aparecida da; Tomazela, Maria das Graças Junqueira Machado; http://lattes.cnpq.br/9920701759600807; http://lattes.cnpq.br/9809874053943708; https://orcid.org/0000-0002-7558-6443; https://orcid.org/0000-0002-5471-2658
Despite the progress women have made in recent decades in terms of participation in the labor market and other spheres of public life, recent studies have revealed growing wage disparities affecting women. Considering the importance of the Information Technology (IT) sector to the Brazilian and global economy, it is essential to discuss wage differences and their impacts, especially on women's professional and personal lives. Therefore, the objective of this study is to analyze the wage disparities faced by women working in the Information Technology field in the city of Sorocaba, identifying and investigating the causes of these differences. The research sought to understand how socioeconomic, cultural, and organizational factors contribute to gender wage inequality in this sector. The study adopted a quantitative-qualitative approach. Initially, an analysis of data from the Annual Social Information Report (RAIS), from 2018 to 2022, for workers in the city of Sorocaba-SP, was carried out, followed by the application of the Oaxaca-Blinder decomposition method using the Python data science programming language. Subsequently, semi-structured interviews were conducted with IT professionals of both genders to investigate their perceptions and experiences of gender discrimination in the workplace. Finally, the research identified wage differences between men and women in the IT sector in Sorocaba, showing a significant increase in disparities: from 9.51% in 2018 to 19.45% in 2022. On average, 95% of this difference was attributed to discrimination. The interviews complemented these findings by offering a deeper understanding of working conditions and the factors that perpetuate wage inequality, revealing a scenario of discrimination, but also highlighting the importance of equity policies and initiatives that promote fairer environments.
Desigualdade territorial: do Grajaú ao ensino superior, as barreiras da mobilidade no espaço periférico
(Universidade Federal de São Carlos, 2026-07-02) Silva, Karina Rosa da; Mariano, Neusa de Fátima; https://lattes.cnpq.br/5003743301847104
The city of São Paulo offers great opportunities, but it also exposes the deep inequalities faced by those living in its peripheries. In the district of Grajaú, in the far south of the capital, these opportunities coexist with daily hardships stemming from a historical process of occupation, expansion, and segregation, which still raises questions today about the future of its residents. In this context, young people's education is directly affected by instability in food security, housing, mobility, and safety, often losing priority in the face of the need to supplement family income, which contributes to school dropout rates. Given this scenario, the research investigates how young people from Grajaú manage to reach higher education, revealing trajectories marked by obstacles but also by the resilience of the territory, analyzed through the lens of Henri Lefebvre and his discussion of the production of urban space, with the aim of understanding the right to, access to, and persistence in higher education for these young people based on their own experiences and accounts.
Proposta de sistema de medição externa para agvs seguidores de linha com documentação elaborada para preservação de legado
(Universidade Federal de São Carlos, 2026-06-30) Sato, Marcelo Itonaga; Morandin Junior, Orides; http://lattes.cnpq.br/4192845106907956
Despite having an MVP of a low cost external measurement system for line follower AGVs, further development of the project wasn’t possible, as it had insufficient documentation which wasn’t up to the laboratory’s standard. As the TEAR laboratory relies on a continuous rotation of undergraduate students every year, the proposed project’s documentation was written from scratch in the form of a Product Requirements Document and a General Architecture Diagram within the SOA architecture, capable of providing a high-level overview of the system and its intended implementation, enabling TEAR members to understand and implement the project. With that documentation, the laboratory’s members were capable of documenting and implementing some of the system’s services while following TEAR’s software development protocol, which resulted in robust services and documentation which will be used by future members of TEAR for its maintenance and updates.
