This research looks at the process of analyzing and adapting games as teaching tools for English language instruction in middle school. This resource comes up as a low-cost, non-digital alternative to boost student motivation. The main goal is to present and analyze the theoretical and methodological aspects of four original games, focusing on accessibility for students with visual impairments. It's a qualitative study, with document analysis and a descriptive-interpretative approach, motivated by the practical challenge of including a blind student in playful activities supported by analog games. The research is based on the principles of inclusive education, Universal Design for Learning (UDL), and the theoretical contributions of John Dewey and James Paul Gee. Based on a reflective analysis of the pedagogical design of the developed games, the study discusses how their tactile features, in braille, the use of enlarged fonts and contrasting colors, along with the collaborative development of an offline digital app prototype designed as an adaptation tool for one of the games, provide structural conditions to support participation and meaningful learning in inclusive English teaching contexts. The study was developed from the teaching experience of the teacher-researcher in public school classrooms, considering specific accessibility needs observed in the school context, especially in serving students who are blind or have low vision. As an educational product, a practical guide was created to support pedagogical activities, helping English teachers use and adapt the games. It is concluded that the combination of playfulness, accessibility, and language teaching can help build more democratic and inclusive teaching practices, providing support for teacher training and for the development of low-cost educational materials aimed at the reality of Brazilian public schools.

This study analyzes landscape dynamics and their effects on ecological connectivity in the Búzi River Basin, Mozambique, integrating spatio-temporal approaches, landscape metrics, and future scenario modeling. Chapter I establishes the conceptual foundation through a systematic literature review, demonstrating that landscape fragmentation, driven by land-use and land-cover changes, is the primary factor reducing structural connectivity. Chapter II evaluates landscape evolution from 1990 to 2024, revealing a significant increase in fragmentation associated with agricultural expansion and anthropogenic pressures. In Chapter III, prospective scenario modeling indicates that continuing current trends is likely to intensify connectivity loss, whereas sustainable strategies may mitigate these impacts. Chapter IV integrates environmental variables and resistance surfaces to model ecological connectivity, identifying priority areas for conservation and delineating ecological corridors using least-cost path analysis. Finally, Chapter V assesses connectivity under future scenarios, highlighting strategic corridors for ecological conservation. The results demonstrate that landscape connectivity is a dynamic process strongly shaped by land-use trajectories and emphasize the need for predictive and integrated approaches to support territorial planning and biodiversity conservation.
Oxidação eletrolílitica por plasma como técnica de alta eficiência para degradação de fármacos
(Universidade Federal de São Carlos, 2026-06-19) Moreira, Bárbara; Souza, Ernesto Chaves Pereira de; http://lattes.cnpq.br/1505400360366643; https://orcid.org/0000-0003-1058-302X; http://lattes.cnpq.br/6424734565517281; https://orcid.org/0009-0008-1566-7365
The increasing detection of emerging contaminants in bodies of waters, particularly persistent pharmaceuticals such as Fluoxetine (FLX), Ofloxacin (OFX), and Diclofenac (DCF), represents a critical environmental challenge in Brazil. Conventional wastewater treatment plants exhibit low efficiency in removing these molecules, necessitating the development of advanced remediation technologies. This study aimed to investigate the potential of Plasma Electrolytic Oxidation (PEO) as an Advanced Oxidation Process (AOP) for the degradation of these compounds. The methodology involved applying the PEO process to solutions containing a mixture of these pharmaceuticals, utilizing plasma micro-discharges to promote chemical decomposition simultaneously with the formation of oxide films. The bibliographic results demonstrated high degradation capacity, with reduction rates exceeding 90% for Fluoxetine and 60% for Ofloxacin and Diclofenac within 60 minutes. Furthermore, a 57.3% reduction in Total Organic Carbon (TOC) was observed, indicating partial mineralization of the pollutants into CO2. It is concluded that the PEO technique is a promising, sustainable, and highly efficient alternative, capable of treating complex pharmaceutical residues without the need for additional external reagents, thereby contributing to the preservation of water resources.

Brazil is a major importer of mineral fertilizers; however, given the global challenges, there is a growing need to develop a domestic market. This study addresses the economic and environmental issues associated with the excessive use of these fertilizers and the industrialization of agriculture. In this context, the development of modern fertilizers with microbiological and organic applications has contributed to increasing nutrient absorption efficiency and promoting sustainability. The dynamics of phosphorus in the soil directly influence its availability; therefore, strategies that increase nutrient availability to plants are necessary. In this context, slow-release fertilizers have become a promising alternative, enhancing nutrient uptake throughout the crop life cycle and enabling the replacement, even if only partially, of traditional fertilizers. An example of these inputs is the bioactive organomineral fertilizer, which provides nutrition through the combination of organic and mineral components, in addition to microbiological activation by fungi and bacteria. This product still requires further improvements; however, it has gained increasing visibility due to its ability to reuse agro-industrial waste, contributing to a circular economy.
Modelagem da permanência no mercado de trabalho formal no estado de São Paulo: uma análise de sobrevivência com dados da RAIS
(Universidade Federal de São Carlos, 2026-06-19) Chun, Renan Silva; Suzuki, Adriano Kamimura; http://lattes.cnpq.br/4579497412852854; http://lattes.cnpq.br/4541667623576581; Suzuki, Adriano Kamimura; Caetano, Sabrina Luzia; Vigas, Valdemiro Piedade; http://lattes.cnpq.br/4579497412852854; http://lattes.cnpq.br/2340330162391128; http://lattes.cnpq.br/0661688648741476
This dissertation investigates the duration of formal employment in the state of São Paulo through survival analysis techniques applied to microdata from the Annual Social Information Report (RAIS). The event of interest was defined as the termination of the employment relationship, while employment ties that remained active at the end of the follow-up period were treated as right-censored observations. The empirical strategy combined descriptive analysis, nonparametric estimation using Kaplan Meier curves with correction for delayed entry (left truncation) and survival modeling through semiparametric (Cox) and parametric approaches, complemented by residual analysis and influence measures to assess the quality of fit. The results reveal substantial heterogeneity in the risk of employment termination according to individual characteristics, establishment attributes, and economic sector. The Cox model clearly described the effect of covariates on the termination risk, while, among the parametric models, the log-normal distribution provided a good overall fit to employment duration and was adopted as the parametric benchmark of the study; its regression extension (an accelerated failure time model), which does not rely on the proportional-hazards assumption, recovered the same ordering of effects as the Cox model, reinforcing the robustness of the findings. It is concluded that survival analysis proved to be an effective and robust framework for studying the dynamics of retention and turnover in the formal labor market, producing a detailed and coherent portrait of employment duration and contributing to more precise diagnoses and to the design of evidence-based public policies. The methodological caveats identified delimit the scope of the results without compromising the consistently observed patterns. As possible extensions of this research, particular emphasis is placed on the explicit treatment of non-proportional hazards, the refinement of parameter specification, and the development of an analysis based on identified RAIS data in a secure research environment, which would allow the follow-up window of the employment relationships to be extended.
