    In the Brazilian context, by 2025, the National Solid Waste Policy (PNRS) marks its 15th anniversary, standing out for one of its maen principles: shared responsibility for the product life cycle, in which public authorities, manufacturers, as well as consumers share responsibility for the impacts resulting from waste generation. In this context, the main objective of this study is to conduct an initial exploratory assessment of solid waste management in the municipality of Atibaia. The research examined two settings: the practices of waste generation and management within a residential complex, and the dynamics involved in the operations of a local recycling cooperative. To this end, the study adopted a mixed quantitative–qualitative approach to preliminarily explore the urban solid waste context in the city. Based on data analysis, structural, operational, and occupational safety challenges were identified within the cooperative, in addition to difficulties related to residents’ engagement in proper waste separation and disposal. The study also found a lack of continuous environmental education initiatives and communication among the involved actors, which poses risks to the efficiency of the recycling process. Drawing from this diagnosis, a guide was developed proposing improvements aimed at community awareness and the implementation of more efficient waste management measures. Thus, the study reinforces the importance of integrating public authorities, cooperatives, and the community to strengthen sustainable urban solid waste management practices and contribute to the objectives of the PNRS.

    Wetlands are ecosystems of extreme importance, both nationally and internationally, but many of them have not yet been properly delineated, which hinders their monitoring and protection. Over the years, there have been several developments in the field of remote sensing and the application of this practice in conjunction with the use of artificial intelligence (machine learning, deep learning), allowing mappings to be carried out remotely and efficiently. Combining these factors, the delineation of wetlands has been conducted in research using different methods. This Systematic Literature Review aimed to compare these methodologies and define which would be the most suitable for the southwestern region of São Paulo, in addition to discussing the role of artificial intelligence in these processes. From this, it was determined that the best method would be the application of a hybrid workflow, combining multisensor data, deep learning, and object-based segmentation, being capable of mapping marshes, wet fields, and palm swamps in the region, as well as highlighting that the role of artificial intelligence is to assist in the process, automating stages and reducing the time required for mapping.

    Food waste is a global phenomenon. A significant amount of food is wasted every year, and this has become a priority issue in international agendas, given its environmental, social, and economic impacts. This process occurs in several phases of the food chain. Food waste in the consumer food service sector is particularly significant. This sector is an important potential source of solid residue, demanding special attention due to the environmental, social, and economic impacts observed in this process. The development of practical actions to reduce food waste in public services can result in not only budget savings but also environmental benefits. In this context, this paper identified the main reasons that lead diners at a university restaurant commit food waste and examines the relationships among these reasons.. After a Literature Review, it was able to identify some reasons that drive customers to food waste. Subsequently, an analytical framework was proposed to measure these drivers empirically. During field data collection, research was conducted with 421 students who use the cafeteria at Mato Grosso Federal University. The techniques of data analysis chosen were Structural Equation Modeling and the Kruskal-Wallis Test. Results confirmed 12 out of 19 tested hypothesis. Statistical analyses confirm twelve of the nineteen hypotheses tested in research on the topic. The results revealed that food waste in university restaurants does not stem from isolated factors, but from a complex network of factorswhethr related to the diner, the environment, or the food. Intrinsic human factors such as behavioral intention and self-awareness showed a more direct relationship with wasted food waste than factors related to the environment or the food. The results suggest a change in the current approach used for campaigns and policies to reduce food waste in canteens.

    This thesis aims to analyze learning recovery in the post-pandemic period in two municipal schools in the interior of São Paulo, seeking to understand how educational policies, pedagogical practices, and teaching experiences were articulated in the face of the challenges imposed by COVID-19. Specifically, it aimed to identify the municipality's guidelines regarding learning recovery, investigate how schools organized learning recovery proposals, understand how teachers understand the proposals and how they develop strategies for student learning recovery, and learn about the participants' significant experiences regarding the learning recovery process, considering the possible reinterpretations of pedagogical action. Based on Vygotsky's Historical-Cultural Theory, the category of experience (perejivánie) is adopted as a unit of analysis capable of integrating subjective and objective dimensions of the educational process, with a focus on actions in favor of learning recovery, highlighting the impacts of the pandemic on teachers and students. The research combined analysis of academic publications, a survey of legislation on learning recovery in Brazil, interviews with teachers linked to the Learning Workshop Project, and observations in participating schools, recorded in field diaries. Among the results obtained, we highlight that the actions of the Department of Education to recover learning were fragmented and poorly coordinated, dependent on the individual efforts of teachers. Projects such as the Learning Workshop and Mediating Learning had limited reach and suffered from a lack of planning, training, and resources. The absence of continuous and integrated policies aggravated educational inequalities and compromised the effectiveness of learning recovery. The study identified conceptual confusion between the terms recovery, reinforcement, and learning recomposition, both in legislation and in teaching practice, which impacts the effectiveness of school actions. The research proposed understanding these modalities as complementary: recovery aims to ensure the appropriation of essential learning that has not been consolidated after its formal approach; reinforcement aims to consolidate, deepen, and expand partially appropriated learning, preventing future gaps; and recomposition aims to intentionally reorganize the curriculum and practices to address structural or contextual learning gaps. Based on Vygotsky's category of experience (perejivánie), it was revealed that the process of post-pandemic learning recovery involved strong contradictions between environment and subject, marked by teacher overload, lack of support, and structural inequalities. It is concluded that learning recovery goes beyond content replacement, requiring the reconstruction of bonds, integrated practices, and public policies that ensure the right to learn with dignity and equity.

    In a global context marked by the devastation of mining, this study investigates how collectives affected by the Samarco dam collapse in Mariana articulate their memories and social suffering to address long-term social damages. The primary objective is to examine the impact of this work of memory on the collective identities of the affected populations and on their relationship with mining enterprises. The research posits that the critical event triggered a situation of sustained social suffering, from which a new structure of feeling emerged among the affected communities. Furthermore, it is argued that the identity-related consequences of the Samarco disaster were of such magnitude that the event can be conceptualized as a cultural trauma. To support these claims, the research draws upon key theoretical frameworks from the fields of Political Ecology, Sociology of Disasters, and Sociology of Culture. The methodology employed is qualitative, centered on documentary and content analysis. Specific materials analyzed include editions of the newspaper Jornal A Sirene, damage matrices produced by organizations dedicated to defending the rights of the affected individuals, and documents from the Campanha Revida Mariana. Additionally, the study incorporates considerations derived from data collected through fieldwork. By examining the memories that emerge from the ruins within mining neoextractivism, the nascent structure of feeling, the future perspectives they engender, and the degree to which the intentions, experiences, and conceptions of the affected subjects are materialized in the disputes over reparation, this research contends that these expedients are crucial for a more precise interpretation of the type, intensity, duration, and forms of damage mitigation resulting from the disaster under consideration.

    Wind energy has emerged as one of the main sustainable alternatives for electricity generation in Brazil. Among the states with the greatest potential, Rio Grande do Norte and Ceará stand out due to their favorable climatic and geographic conditions, which ensure strong and consistent wind regimes. However, the availability of this resource is highly dependent on climatic variability, making it essential that long-term energy planning incorporates reliable projections of future wind behavior. This study analyzed climate scenarios proposed by the Intergovernmental Panel on Climate Change (IPCC) and their potential impacts on the wind energy sector, using outputs from Global Climate Models (GCMs) regionalized through the Eta model (BESM, CanESM2, HadGEM2-ES, and MIROC5), subsequently refined through machine learning techniques. Historical observational series were integrated into these projections, resulting in a hybrid modeling framework capable of providing high-accuracy forecasts for the next three decades. The results indicate a general trend of slight decreases in mean wind speeds, ranging from 2% to 7% by the mid-21st century. Ceará shows a more stable and homogeneous pattern, with modest reductions and low spatial variability, while Rio Grande do Norte exhibits more heterogeneous declines, particularly in inland areas. Despite these projected reductions, both states remain highly favorable for wind power expansion and for strengthening the green hydrogen production chain, consolidating the Northeast region as a strategic axis in Brazil’s energy transition.

    The present Undergraduate Thesis aims to investigate how the pedagogue can act as a cultural mediator in music, seeking to ensure its meaningful presence in the daily life of Elementary School’s Early Years. For this purpose, through qualitative bibliographic research, the study sought to reflect on the lack of music education subjects in Pedagogy courses, the issue of social media platforms such as TikTok, Reels, and YouTube currently being privileged channels for children’s music consumption, the concept of cultural mediation, and the possibilities of action for pedagogues in music mediation. The results indicate the importance of recognizing music as an artistic language and a field of knowledge that should be included as a subject in the Pedagogy curriculum, requiring specialized teachers to teach it in higher education, so that non-specialist teachers working in Early Childhood and Elementary Education receive essential musical education for pedagogical work with children. They point to the importance of the pedagogue acting as a mediating agent in music to integrate it meaningfully into pedagogical practices. They also reveal that, despite the media appeal of mass music that promotes standardization and musical impoverishment, it is possible to carry out pedagogical practices committed to musical quality in childhood.

    This research aims to explore how the learning of cross-cutting themes can contribute to the health of participants in a social basketball project. Using a qualitative approach, the study was conducted at the ASPA Institute, in Araraquara/SP, with children aged 7 to 10 years, through a pedagogical intervention consisting of six cross-cutting activities distributed across three thematic blocks. Data collection included semi-structured interviews with the participants of the local unit, the coordinator of the Multidisciplinary Department, and the reference Physical Education teacher of the social project, as well as field notes and documental analysis of the Institute’s Bylaws and Reference Guide. Data were analyzed using Structural Content Analysis (ANCO), based on isotopies, in order to identify recurring meanings in the participants’ statements and experiences. The theoretical framework is grounded in Jorge Larrosa-Bondía’s notion of experience, articulated with the health concepts from the Ottawa Charter (1986) and the 8th National Health Conference (1986). The results indicate that the implementation of cross-cutting themes within the context of educational sport is related to the health of children participating in the social project, strengthening bonds and expanding learning beyond the court, not limited to the biological dimension alone. The study contributes to the health debate by discussing the role of educational sport in promoting the health of children in situations of social vulnerability, reinforcing the importance of an interdisciplinary approach in Physical Education.

    Seeking to understand how a curriculum is constructed within a school seems to be a relevant aspect that could contribute to physical education in schools. This research is a case study based on a private school founded in 1994 which, based on the interest and initiative of its physical education teachers, created and adopted, in 2011, a Physical Education curriculum that includes various contents, themes, and activities to be taught, addressing the theoretical, historical, and sociocultural aspects of physical practices and, before competition, the appreciation of factors such as cooperation and integration in sport. Thus, the objective of this study was to analyze the process of constructing and implementing the Physical Education curriculum of a private cooperative school in the school system of the city of São Carlos, São Paulo. The research was qualitative in nature and used semi-structured interviews with four Physical Education teachers from the school who participated in the process of creating and implementing the curriculum, as well as documentary analysis of meeting minutes related to the period in question, for data collection. The data analyzed led to the creation of four categories of analysis, namely: a)Physical Education building a new role in school, in which we highlight the main aspects that an updated view of the discipline should value for a rich and diverse approach; b) What to teach in each teaching cycle and how to approach the content, in which we discuss the main content and topics to be taught in each teaching cycle; c) Relationship with guiding and reference curricula, in which the teachers interviewed commented on the theoretical references of the discipline and especially on those that influenced the analyzed curriculum structure; d)“External” conditions and interdisciplinarity, in which we analyze important aspects to be taken into consideration beyond the content addressed, aspects that are important to assist in the success of a curriculum project. Thus, based on the research conducted, we identified that a diversified and pluralistic approach, which values specificities, interdisciplinarity, practical aspects, and theoretical aspects, is the most appropriate path to achieve Physical Education that fulfills its objective of developing critical individuals through the culture of physical movement. In addition, we highlight the importance of addressing, in future work with other possible study methodologies, the theoretical references present within the area and the implementation of thematic units and content for all cycles of basic education, from early childhood education to high school.

    In this work, we study toric varieties as well as related objects, such as hypersurfaces, along two lines of research. In the first part, we establish conditions on a family of functions defined on an arbitrary toric variety, ensuring that the associated family of hypersurfaces is Whitney equisingular. In the second part, we present a toric structure for the 2-generic symmetric determinantal variety, together with a detailed study of the combinatorics of the cone associated with this structure. As an application, we obtain a formula for computing the Euler characteristic of the Milnor fiber of functions with an isolated singularity at the origin defined on them. Using this formula, we compute the local Euler obstruction of the 2-generic symmetric determinantal variety at the origin. Altogether, the results contribute both to the study of Whitney equisingularity in toric varieties and to the combinatorial and topological understanding of generic symmetric determinantal varieties.

    The research examines the extent to which Direct Action of Unconstitutionality (ADI) No. 4650 reflected disputes between political and economic elites within the Brazilian Supreme Federal Court (STF), based on the 2015 ruling that declared corporate financing of electoral campaigns unconstitutional. The theoretical framework draws on contributions from the Sociology of Law, which conceptualizes the STF as an arena of dispute among political groups, guiding the analysis toward an understanding of how legal reasoning and social pressures intertwine in the decision-making process. Methodologically, the study employs documentary research and thematic content analysis applied to the initial petition, the justices’ opinions, the 2013 public hearing, and the amicus curiae submissions. The results indicate a predominance of arguments grounded in the principles of equality (isonomy) and anti-corruption, mobilized by different actors involved in the proceedings. These arguments reveal the construction of a discourse in defense of political equality and the integrity of the democratic process in a context marked by the emergence and consolidation of Operation Car Wash and the increasing delegitimization of the political system. A low level of mobilization of the right to freedom of expression was observed, as it was treated marginally in comparison with the emphasis placed on republican values and the fight against fraud. This suggests that the decision was influenced by both legal reasoning and the broader social pressures of that period. The research contributes by highlighting the role of the STF as a space of symbolic and institutional dispute among political groups, shedding light on the limits and potential of judicial review in contexts of representative crisis.

    Parabens are a class of preservatives widely used in cosmetics, pharmaceuticals, and food products due to their antimicrobial properties and cost-effectiveness. Recently studies highlighted potential harmful effects associated with these preservatives, including hormonal dysregulation and increase risk of cancer and, in infants, parabens are associated with skin reactions and immunological dysregulation. Graphene oxide-based sorbents have been used on extraction of cosmetic ingredients and graphene oxide (GO) modification can enhance sorbents selectivity. This study developed and optimized an analytical method for the detection and quantification of parabens (methylparaben, ethylparaben, propylparaben and butylparaben) in cosmetic samples (cleanser, moisturizer and sunscreen) using dispersive solid-phase microextraction (D-μSPE) coupled with high-performance liquid chromatography with ultraviolet and visible light detection (HPLC-UV/Vis) and mass spectrometry (HPLC-MS/MS). GO-based sorbents modified with ionic liquid, as well as commercial sorbents, were evaluated by dispersive solid-phase microextraction (D-μSPE) and microextraction by packed sorbent (MEPS). The sorbent functionalized with zwitterionic liquid, ViImC4S@GO, exhibited superior extraction capacity compared to other sorbents. A methodology was developed using dispersive solid-phase microextraction (D-μSPE), based on the parameters such as sorbent amount, desorption solvent, solvent volume, extraction time, elution time, and sample volume; and method performance was assessed through figures of merit including selectivity, limit of detection (LOD), limit of quantification (LOQ), linearity, precision, accuracy, and matrix effect. Finally, the developed method was applied to real samples.

    The changes in land use and occupation generate various impacts on the environment, including hydrological impacts, such as changes in the volume and peak flow of surface runoff. The implementation of the Lagoa do Sino campus of the Federal University of São Carlos (UFSCar) is no different and has the potential to generate these impacts. In this context, this study aims to assess the hydrological impacts of the implementation of the Lagoa do Sino Campus of UFSCar through hydrological modeling using HEC-HMS software, and to propose mitigating measures for these impacts. Understanding these potential impacts enables the adoption of mitigating measures throughout the campus's implementation, which is the most favorable phase for this. The results showed that the “Future” scenario, that is, the scenario of full implementation of the campus, will have a modest increase in peak flow and volume drained compared to the “Past” and “Present” scenarios, however the result obtained of a non-significant increase is due to the expansion of the permanent preservation areas (APP) located on the Lagoa do Sino Campus.

    Citrus farming is one of the most economically significant agro-industrial chains in Brazil and worldwide, generating approximately 50 to 60% of solid and liquid waste during fruit processing, mainly in the form of peels, pulp, and seeds. Inadequate management of this waste leads to high disposal costs and significant environmental impacts, such as methane emissions, soil acidification, and water contamination. This study aimed to investigate the economic and environmental feasibility of composting citrus waste as an organic fertilizer, within the context of the circular economy and ESG principles. The research, applied in nature and using a mixed (qualitative and quantitative) approach, was conducted through a theoretical exploratory study adapting the economic feasibility model of Culas, Anwar, and Maraseni (2025), considering an average productivity of 869 boxes of oranges per hectare, an annual mineral fertilizer cost of BRL 2,245.35/ha, and a theoretical application of 7 tons of organic compost per hectare. The results showed that the partial replacement (25–75%) of mineral fertilizers with citrus compost provided economic co-benefits ranging from BRL 51.25 to BRL 1,544.01 per hectare per year, representing up to 69% savings over the cost of conventional inputs, with greater returns observed in high-quality soils. The compost presented a C/N ratio of 15:1, pH between 3.5 and 4.0, and high levels of organic matter, nitrogen, phosphorus, and potassium, promoting improvements in soil fertility, cation exchange capacity, and microbial activity. Environmentally, the process showed potential to reduce waste disposal costs by up to 35% and mitigate greenhouse gas emissions, directly contributing to SDGs 2, 12, 13, and 15.

    Este trabajo problematiza la forma en que la temática de la creación literaria se constituye como un elemento central en la novela O cemitério dos vivos (1921), de Lima Barreto. Partiendo de una crítica literaria que frecuentemente asoció la obra con sus aspectos biográficos, la investigación busca profundizar en los procesos dinámicos de creación del escritor, reconociendo, en el tema de la creación literaria, el eje estructurador de la narrativa, dado que la novela se organiza en torno a la elaboración de un libro por parte del narrador Vicente Mascarenhas. Se observa que el acto de labor literaria promovido por el narrador configura una reflexión sobre el papel social del escritor en las primeras décadas del siglo XX y cuestiona la concepción de literatura vigente en la época, al mismo tiempo que evidencia los desafíos de mantenerse en los espacios de legitimación literaria.

    This work presents a reflection on cultural mediation in the school context, focusing on the teacher's role in bringing children closer to art, specifically drawing, as a form of expression and knowledge. Using a qualitative and bibliographical methodology, the study sought to understand how the mediation process, carried out through sensitive listening, can stimulate creation and dialogue between children and works of art. The research was developed based on authors who discuss art and pedagogy as fields that intertwine in human formation, highlighting the importance of the teacher acting as a mediator in art. The results indicate that preschool is a privileged place for children to come into contact with the arts, and that cultural mediation by teachers, as an attitude of listening, of being among many, of learning together, contributes to the aesthetic experience, to the wholeness of the child's presence with themselves, with others, with material objects, and with space, enabling them to experience their personal, historical, and cultural identity more fully, while enriching teaching practice, making it more reflective and meaningful.

    Nature is fundamental theme today, children whith respectful experiences with nature tend to develop attitudes of respect and preservation of the enviroment. Children and their experiences with and in nature in Early Childhood Education, reflections on pedagogical practice permeate this research. This is an investigation, conducted at an Early Childhood Education Center in the cith of Sorocaba/São Paulo, sought to understand how children aged 2 to 4 establish their experiences through play in nature in colletive contexts, using photography as a participation strategy. The methodology adopted followed the qualitative approach, whith action research as the chosen method. The theoretical framework of this study is baseado n Tiriba, Freinet, Barbosa and Horn, Gadotti and the Curricular Guidelines in Early Childhood Education to discuss Childhood and Nature. Piorsky, Kishimoto, and Louv tolead the discussion about playing in nature. Mallaguzzi and Bondia to discuss language. Barros, Barthes, Vill, Vieira contextualize photography in research. Weffort, Infantino, Cohn to discuss the sensitive gaze and child protagonism. The research data are the image productions made by the children and the teacher. This study made it possible to reflect on the practice of photographic recording as a listeng strategy in Early Childhood Education, as well as a form of expression that allowed the teacher to have a more sensitive look at children´s experiences. It also contributed to understanding the school as a place for experiences for the children were approached as a form of visual narratives, providing new experiences for the children and the teacher through the exercise of observation and listening, and also though the construction of their pedagogical documentation, for which photographic production whith and by the children was na essential elemento. By examining her own practice to give visibility to the children´s particopation, the teacher became a protagonist, and the children appropriated new concepts constructed in the educational contexto. As a final product of this research, a blooklet of suggestions on playing with and in nature in early childhood education.

    This undergraduate thesis was structured into two complementary chapters. Chapter 1 presents the theoretical framework and justification of the research, addressing the issue of botanical imperception—defined as the difficulty individuals face in recognizing the importance of plants in ecosystems and human life. It discusses cultural, pedagogical, and neurophysiological causes linked to traditional Botany teaching and highlights the need for active learning methodologies, such as learning by doing, in non-formal environments. Within this context, the study proposed the use of a Sensory Garden (SG) as an educational tool that integrates sensory perception, emotion, and scientific knowledge to foster meaningful learning and environmental awareness. Chapter 2 consists of the scientific article that implemented this approach. The study was carried out with 22 students from the technical Agronomy program at Escola Estadual Ivens Vieira (Angatuba/SP), in partnership with the Conservation Biology Laboratory at the Federal University of São Carlos – Lagoa do Sino Campus (Buri/SP). The experimental design included theoretical lectures and practical activities in the SG. Statistical analyses (Student’s t test and chi-square test) revealed no significant differences between the trea and control groups (p > 0.05), leading to acceptance of the null hypothesis. Nevertheless, qualitative observations demonstrated greater engagement and curiosity among students involved in practical tasks, underscoring the SG’s formative potential for Botany education and its capacity to promote a more sensitive and lasting botanical perception.

    The discharge of effluents without proper treatment is one of the main causes of pollution in water bodies, leading to a series of environmental problems that demand solutions combining environmental compliance and operational viability. In this context, bioremediation stands out as an alternative to optimize the efficiency of stabilization ponds in the dairy sector, aiming for a more sustainable, low-cost treatment with high pollutant removal capacity. This study evaluated the efficiency of phytoremediation using aquatic macrophytes in a facultative lagoon employed for the treatment of effluents from a processed dairy industry, located at the Savencia Brasil unit in Angatuba, São Paulo. The research aimed to verify the technical and environmental feasibility of applying the species Pontederia crassipes Mart., Canna x generalis, and Cyperus alternifolius L. to improve effluent quality and reduce organic load. The physicochemical and statistical monitoring of parameters such as pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), and chemical oxygen demand (COD) demonstrated that the system performed satisfactorily, achieving an average BOD removal efficiency of 89.5% and COD removal above 80%, while maintaining pH levels within legal limits. The plant development of the root system and the high colonization capacity of the macrophytes favored the retention of suspended solids and stimulated microbial activity, enhancing effluent quality improvement. Seasonal variations and occasional operational interferences, such as breakage of containment areas and replanting periods, temporarily influenced performance but did not compromise treatment stability. The results demonstrated the potential of phytoremediation as a biological treatment model for dairy industry effluents. This technology represents an efficient, low-cost, and environmentally sustainable alternative, contributing to effluent compliance with current legislation and promoting local ecological benefits.
