Nanotechnology applied to cosmetology represents a significant breakthrough in the delivery of active ingredients, seeking to overcome the permeation limitations of conventional formulations. This study aimed to critically analyze, through a qualitative literature review (Web of Science, Google Scholar, and SciELO), the influence of nanostructured systems on the stability and shelf life of cosmetic products. Unlike a generalist approach, the results evidenced that nanostructuring does not inherently provide absolute stability, as these are thermodynamically unstable systems. It was analytically established that solid matrices—such as Solid Lipid Nanoparticles (SLNs) and polymeric nanocapsules—offer superior structural protection against degradation and premature leakage of the active ingredient when compared to fluid systems, such as liposomes and nanoemulsions. In the context of quality control, it was found that the application of stability studies governed by ANVISA guidelines is indispensable, yet insufficient to certify the integrity of nanosystems. Aligning with the FDA's regulatory requirements for nanomaterials, shelf life validation mandatorily requires instrumental monitoring through Dynamic Light Scattering (DLS) and Zeta Potential. In conclusion, although nanotechnology optimizes cosmetic performance, its wide application still faces critical challenges and limitations, notably the gaps in nanotoxicology regarding involuntary systemic absorption, the high cost of characterization, and the severe mechanical obstacles involved in industrial scale-up.

Hospital organizations are well-known for their concern in ensuring safety and quality in the services provided to their users. The use of tools to evaluate these services emerges in this context. Thus, this research aims to investigate the current national scenario of Hospital Accreditation and relate the findings to the care model produced in the health field. A Systematic Literature Review was conducted through a search in databases, using the descriptors: Hospital Quality, Hospital Quality Certification, and Hospital Accreditation. The following filters were applied: full text and availability, documents of the scientific article type, and publication year from 2019 to 2024. The PRISMA 2020 flowchart was applied, and an analytical framework was constructed to organize the material. This research sought to delve into the field of Science, Technology, and Society, connecting it to the field of Health, considering that the latter uses science and technology to protect, restore, and maintain the health, well-being, and quality of life of people in society. Therefore, it was important to address, along this path, some concepts about work in healthcare (its protagonists and products), the technological apparatus involved, and the healthcare system that structures the process of seeking a cure, reducing pain and suffering, and rehabilitating and maintaining life, within the Brazilian context. Thus, the programs and organizations that work in the accreditation and certification process of healthcare services in Brazil were analyzed in an attempt to relate them to the technologies involved in healthcare.

Considering the increasing prevalence of dementia in older adults and its functional, neuropsychiatric, and psychosocial impacts on affected individuals and caregivers, it becomes relevant to investigate non-pharmacological strategies that are accessible and applicable in different care contexts. Multicomponent physical exercise programs combined with cognitive exercises, delivered via telehealth and using a multidisciplinary approach, may represent a promising alternative for health promotion, functional maintenance, and the reduction of caregiving burden. The main gap is the lack of studies that investigate, in an integrated and multidimensional way, the effects of multicomponent telehealth interventions, combining synchronous and asynchronous strategies, on the caregiver-older adult with dementia dyad, stratified by physical activity level (PAL). Thus, it is hypothesized that physical activity acts as an associated and potentially modifying factor of multidimensional outcomes in the dyad, and that a multicomponent intervention via telehealth may promote better outcomes for both. The overall objective was to investigate the level of physical activity in older adults with dementia and their caregivers, analyzing its associations with variables such as physical activity level, neuropsychiatric disorders and quality of life of older adults with dementia, and stress, burden and quality of life of caregivers, as well as the effects of a multicomponent exercise program via telehealth on the level of physical activity and related outcomes in this dyad. This doctoral thesis comprised three main studies that addressed the theme of telehealth and older adults with dementia and their caregivers during the COVID-19 pandemic. Study I aimed to evaluate the PAL of caregivers of older adults with dementia, considering stress, burden, and quality of life (QoL) during the COVID-19 pandemic. It consisted of a cross-sectional study with 89 caregivers of older adults with dementia who were assessed via Google Meet video call using the following instruments: International Physical Activity Questionnaire – short version (IPAQ); Perceived Stress Scale (PSS) and Zarit Burden Scale (ZARIT); Quality of Life in Alzheimer's Disease (QoL-AD) caregiver version. The results demonstrated a negative correlation between METs-minutes/week and caregiver burden, showing that the higher the PAL, the lower the burden; and a positive correlation between METs-minutes/week and QoL, showing that the higher the PAL, the higher the QoL. No correlation was found between PAL and stress. Furthermore, significant values were found for the model that includes caregiver burden in relation to METs. It was concluded that PAL proved effective in reducing caregiver burden and increasing QoL. Study II aimed to evaluate the associations between cognition, functionality, neuropsychiatric disorders (ND), and QoL with PAL in older adults with dementia. It consisted of a cross-sectional study composed of 80 older adults with dementia. They were assessed using the Clinical Dementia Rating Scale (CDR); the Baecke Physical Activity Questionnaire modified for older adults (BAECKE); and the Quality of Life in Alzheimer's Disease Scale (QoL-AD) older adults version. A 10-item version of the Neuropsychiatric Inventory Questionnaire (NPI – Q10) reported by caregivers in older adults with dementia. The results demonstrated significant correlations between PAL and cognition, QoL, and functionality. No significant correlation was found with ND. It was concluded that in older adults with dementia, higher PA was associated with better cognition, QoL, and functionality. Study III aimed to investigate the effect of a telehealth-based physical and cognitive exercise program intervention on PAL, as the primary outcome, in older adults with dementia. Secondarily, it investigated the effect of a physical and cognitive exercise program intervention, moderated by the initial PAL of older adults with dementia, on ND and QoL, and on caregiver burden, stress, and QoL. This consisted of a Randomized Controlled Clinical Trial, with pre-intervention, post-intervention (three-month) assessments and a three-month follow-up, comprising 80 dyads of older adults with dementia and their caregivers, randomly divided into two groups: Intervention Group (IG) and Control Group (CG). In the IG, older adults with dementia performed a protocol of physical and cognitive exercises through telehealth. Their caregivers received psychoeducation with guidance on dementia and coping with social distancing during COVID-19. The CG received only psychoeducation at the beginning of the proposed period and was questioned monthly about possible clinical events during the research period. The instruments used with the elderly person with dementia were: CDR; BAECKE modified for older adults; QoL-AD, older adults version; 10-item version of the NPI – Q10; The following instruments were applied to caregivers: IPAQ - short version; PSS; ZARIT; QoL-AD - caregiver version. The main results showed that the IG presented significantly higher physical activity levels (PA) than the CG at the 25th, 50th, and 75th percentiles post-intervention (270%, 220%, and 154% increase, respectively) and at follow-up (54% increase). For secondary outcomes, paired comparisons between groups post-intervention showed that, moderated by PAL at baseline, caregiver QoL values were significantly higher in the IG than in the CG. The physical exercise program, delivered via telehealth, was able to increase PAL in older adults with dementia, and these effects were maintained after the intervention and after the follow-up period. The findings reinforce the importance of structured exercise programs as a complementary strategy for care and prevention of functional decline in these populations.

Objective: To study the perception of healthcare professionals within a multidisciplinary team in the context of on-the-job training, active learning methodologies as a teaching practice, and the use of health technologies in the act of care. Method: This qualitative research used focus groups to collect data, aiming to evaluate the on-the-job training program according to the professionals' perceptions, and data on the use of care protocols as a health technology in care practice. The study was conducted in a large philanthropic hospital in the municipality of Limeira/SP, with the participation of healthcare professionals who make up the multidisciplinary team. The research was approved by the Research Ethics Committee. Results: The professionals described their responsibility towards learning during the training sessions, reflected on their progress, challenges, and weaknesses. They reported the opportunity to build a team based on shared knowledge, achieved through the development and application of care protocols grounded in the best scientific evidence, with the use of technology grounded in the act of care. Conclusion: On-the-job training for healthcare professionals can be strengthened through the use of active teaching methodologies, with both intellectual and social impact. Healthcare delivery relies on technology, which should be used with a focus on providing quality, user-centered care.

Faced with the challenges inherent in improving the quality of Brazilian education, those related to raising the level of student performance in the context of literacy and reading comprehension emerge. Whether in literacy cycle classes (1st and 2nd year of Elementary School) or in Remedial/Reconstruction of Learning classes, teachers need to be supported and subsidized to build meaningful work. The research question guiding this study is: what knowledge is essential to the Knowledge Base of a literacy teacher working in the context of Learning Recovery/Reconstruction and in regular classes of the initial years of Elementary School? The objective is to analyze the teacher learning mobilized/constructed within the context of a training proposal in the area of Continuous Learning Recovery/Reconstruction, focusing on literacy and reading comprehension, aiming at a possible outlining of the literacy teacher’s Knowledge Base and, consequently, their professional development. The approach used in this study is qualitative research, especially collaborative research through an intervention, based on the ideas of Ibiapina (2008) and Mizukami (2000; 2010). The training action involved the planning and implementation of a hybrid training proposal in the area of Continuous Learning Recovery/Reconstruction, focusing on literacy and reading comprehension. This training action began in the first semester of 2024, with a workload of 120 hours and certification. This training was conducted by the UFSCar extension program and made available to teachers working in the Municipal Education System of Bebedouro (SP), with 38 teachers completing the activity. Data sources included the researcher’s logbook; questionnaires; narratives (training memoir, teaching cases, report of pedagogical practices); and a conversation network. Data analysis employed the content categorization technique of Bardin (2016) and Franco (2018), except for the analysis of narratives. The research analysis was structured and unfolded around three key ideas: the research subjects; collaborative processes triggered to expand the Knowledge Base of literacy teachers; and indicators of theoretical-practical contributions to the Knowledge Base of literacy teachers. The results, through the participants’ discourses, show that, especially in the collaborative proposals outlined, new conceptions, theoretical/methodological resignifications, and significant reflections emerged about the Pedagogical Content Knowledge of the literacy teacher, working in regular classrooms or in the context of Continuous Learning Reconstruction/Recovery with a focus on literacy and reading comprehension. Based on the teachers’ observations, it was possible to construct a suggested training guide entitled “Essential Elements of the Pedagogical Content Knowledge (PCK) of the teacher to teach literacy/reading comprehension from the perspective of the BNCC”, in addition to guidelines for adjusting this guide to the need to recover/compose learning. Such evidence may contribute to effectively improving teacher training (initial and continuing) and teaching and learning in classrooms, as well as to fostering public policies or teacher training programs in this area.

This dissertation presents a literature review aimed at analyzing the roles and functions attributed to science fiction works within the field of science education research, addressing the following research question: How and for what purposes has science fiction been incorporated—or proposals for its incorporation have been developed—into science education? To conduct this analysis, a Content Analysis based on Bardin's methodological framework was applied to the studies comprising the research corpus, namely publications addressing the relationship between science fiction and science education, retrieved from the CAPES Journal Portal. The analysis was carried out by adopting the term science fiction as the Unit of Record and organizing the Context Units into analytical tables, in which relevant excerpts were identified, interpreted, and coded to determine the perspectives through which discussions of cultural aspects aimed at fostering a dialogue between science and art are incorporated. As a result, six distinct ways in which science fiction and related issues are addressed, or proposals for their incorporation are developed, within the context of science education were identified. These findings are discussed in dialogue with the theoretical framework developed throughout the dissertation, highlighting the importance of incorporating literature, particularly science fiction, into science education.

This thesis investigates the interconnections between Science, Technology, and Society (STS) through the analysis of the dynamics associated with the topic of Covid-19 vaccination in the Twitter/X environment, starting from the second round of the 2022 Brazilian presidential elections and its subsequent reconfiguration between 2024 and 2025. The research seeks to understand how the socio-technical configurations of the platform participate in the structuring and amplification of discursive disputes involving scientific themes in a context of polarization. The interdisciplinary approach mobilizes Actor-Network Theory (ANT) and Controversy Cartography (CC) as theoretical-methodological tools for mapping the socio-technical networks that comprise the investigated phenomenon through the adaptation of Oligoptic Maps (OM) to the digital environment. Empirically, this work articulates the exploration of The Interfaces Twitter Elections Dataset (ITED-Br), the third largest dataset of tweets with political purposes in the literature, with an ethnographic approach based on the analysis of hashtags, tweets, and user profiles. The results show that scientific themes are incorporated into broader symbolic disputes, marked by dynamics of polarization and deeply influenced by the platform's sociotechnical configurations. The thesis contributes to the advancement of STS studies by offering tools for understanding the relationships between digital platforms, scientific discourses, democracy, and contemporary socio-political dynamics.

Brazil suffers from periodic floods, flash floods, inundations, and urban waterlogging. Some of the causes include: the notion that nature should "adapt" to human needs and desires; urbanization and, consequently, the rapid, uncontrolled, and indiscriminate sealing of urban soils; and a historical preference for "gray engineering" solutions. Thus, it is increasingly necessary to efficiently predict the occurrence of floods. A major difficulty in making such predictions, however, is the lack of hydrological monitoring data, especially flow data. Synthetic rating curve methods have emerged as an alternative. This research aims to generate theoretical rating curves for water bodies in São Carlos using PCSWMM software, and to compare theoretical and empirical curves. The study involved a literature review, data collection and survey, hydrodynamic modeling in PCSWMM, and a comparison between empirical and synthetic rating curves. The development of a hydrodynamic model and the generation of synthetic rating curves open up new possibilities for understanding urban flood processes. Furthermore, they represent progress toward improving the quality of risk management during extreme events. The model developed in this study resulted in a synthetic rating curve capable of adequately representing the overall dynamics of the events, especially the peaks and peak times—that is, the shape of the hydrograph. However, the curve tends to overestimate low flows and underestimate very high flows. Despite these limitations, it is concluded that the synthetic rating curve obtained is indeed applicable to urban flood risk management.

This research investigates the Historical Geography of the Liberdade neighborhood in the city of São Paulo, aiming to understand how the process of space production operated a memoricide of Black territorialities in favor of consolidating an exclusively Oriental identity. The study uses as its main analytical tool and geohistorical document the comic book “Mukanda Tiodora,” by Marcelo D’Salete, which reconstructs the landscape and daily life of the Black population in 1866 based on real letters from the enslaved Teodora Dias da Cunha. Methodologically, the work is based on the perspective of Maurício de Abreu, articulating diachronic and synchronic dimensions to analyze spatial transformations. The investigation confronts the hegemonic narrative that limits the neighborhood's identity to Japanese immigration, rescuing the nuances of the Afro-Brazilian presence in landmarks such as the old Largo da Forca, the Capela dos Aflitos, and the Igreja do Rosário dos Homens Pretos. This work discusses how the “Oriental Plan,” implemented in the 1970s, promoted a deliberate “orientalization” of the neighborhood for tourism and marketing purposes, deepening the symbolic erasure of Black roots. Finally, the dissertation examines contemporary political and symbolic disputes in Praça Liberdade África-Japão, highlighting the renaming of the public space and the installation of the statue of Madrinha Eunice as mechanisms of decolonial resistance and an attempt to restore the dignity of silenced historical subjects.

Cette étude vise à explorer, au sein de la philosophie de Bergson, la question de l'attention portée à la vie. À travers l'étude de sa théorie de la perception, nous chercherons à vérifier la possibilité, défendue par ce philosophe, que la philosophie, par un processus de conversion de notre attention – toujours confinée au strict champ de l'action – en intuition, au sens où ce terme est employé dans sa philosophie, c'est-à-dire comme possibilité d'accéder à la réalité en mouvement et en transformation, puisse permettre cette conversion. À cette fin, nous dialoguerons avec l'art et les modalités de sa production, Bergson l'indiquant comme exemple de cette possibilité de conversion. Existe-t-il un moyen d'échapper à cette limitation qui conditionne notre vision de la réalité ? La philosophie de Bergson propose-t-elle une voie de sortie permettant de dépasser une vie déterminée par la nécessité d'agir pour éviter les dangers ou obtenir des avantages dans son rapport à la réalité ? Est-il possible de « […] revenir à la perception, de la faire s'étendre et s'étendre » (Bergson, 2006, p. 154) ?

Chronic respiratory diseases (CRD) are frequently associated with multiple coexisting chronic conditions, characterizing multimorbidity. The presence of these conditions may worsen functional limitation and contribute to exercise intolerance, a key determinant of prognosis and quality of life in this population. However, the magnitude of the association between multimorbidity and exercise capacity in individuals with CRD remains unclear. This study aimed to conduct a systematic review and meta-analysis of the association between multimorbidity and exercise capacity in individuals with CRD. METHODS: Searches were conducted in PubMed, Scopus, Embase, Web of Science, VHL, and CINAHL from inception to July 2025. Observational studies evaluating exercise capacity in individuals aged ≥18 years with CRD, with and without coexisting conditions, using laboratory or field-based tests were included. Methodological quality was assessed using the Joanna Briggs Institute tools. Meta-analyses were performed when at least three studies reported comparable outcomes, using random-effects models. RESULTS: A total of 49 studies were included in the qualitative synthesis, comprising 28,972 participants, of which 26 were included in the quantitative synthesis. The overall meta-analysis showed that multimorbidity was associated with a reduction of approximately 42 m in the six-minute walk distance (6MWD) (mean difference: −42.0 m; 95% CI −55.6 to −28.5; p < 0.001; I² = 83%). Similar reductions were observed for metabolic (−45.5 m; 95% CI −74.0 to −17.2; p = 0.002), cardiovascular (−48.2 m; 95% CI −72.6 to −23.9; p < 0.001), and mental comorbidities (−29.5 m; 95% CI −54.9 to −4.2; p = 0.023), indicating a clinically meaningful impact. The certainty of evidence was rated as very low, mainly due to the observational design of the included studies, heterogeneity across results, and risk of bias. CONCLUSIONS: Multimorbidity is associated with reduced exercise capacity in individuals with CRD, although the certainty of evidence is limited. These findings highlight the importance of considering coexisting chronic conditions in the assessment and clinical management of these patients.

This research employs a critical-interpretive perspective to analyze "Reading Rooms" within the São Paulo state school system as innovation ecosystems. Drawing upon the theoretical frameworks of information management and information literacy, the study examines the pivotal role of the Articulating Professor in the digital age. The primary objective is to discuss the extent to which these environments and professionals can integrate public policies, digital technologies, collections, and pedagogical practices to foster student authorship and digital citizenship. Methodologically, the study adopts a qualitative, bibliographic approach based on a systematic literature review spanning the years 2015 to 2025. This is complemented by a documentary analysis of national and state-level regulatory theoretical frameworks concerning school libraries and Reading Rooms. The research corpus was assembled through comprehensive searches in national and international databases, followed by rigorous screening, eligibility assessment, and thematic content analysis. The findings demonstrate, first, that Reading Rooms have solidified their position as strategic hubs for mediation and the democratization of information access, despite being hindered by disparities in infrastructure, teacher training, and curricular integration. Second, the results indicate that the mere presence of digital technologies does not inherently guarantee pedagogical innovation; success depends on informational curation, the systematic documentation of practices, the sharing of experiences, and the institutionalization of routines for producing pedagogical knowledge. Third, the study reveals that the Articulating Professor tends to assume leadership in Information and Knowledge Management processes within the school, although frequently without sufficient institutional support or robust continued education policies. As a theoretical-analytical synthesis, the research proposes the Integrated Knowledge Management Model for Reading Rooms (MIGCSL). This framework organizes axes, processes, roles, and indicators to guide future diagnostics, planning, and research on these environments as ecosystems of educational innovation. The study concludes that strengthening Reading Rooms as informational and learning ecosystems requires the alignment of legal theoretical frameworks, infrastructure investment, the professional valuation of the Articulating Professor, and Knowledge Management strategies focused on equity and quality in basic education.

This study aims to analyze what knowledge, from the perspective of school principals, is mobilized and how it guides their decisions and practices in monitoring teaching processes, considering the multiple administrative, political, and pedagogical demands that strain the exercise of their role. The research, exploratory in nature and with a qualitative approach, was developed as a case study in a Municipal Education Department in a city in the interior of the State of São Paulo. The investigation sought to understand what knowledge is mobilized by school principals and how this knowledge guides their decisions and practices, as a relevant part of pedagogical management, in monitoring teaching processes, considering the multiple administrative, political, and pedagogical demands that strain the exercise of their role in the daily school routine. The hypothesis was that the multiple demands placed on school administrators limit the systematic monitoring of the teaching process, which is not a priority, favoring the prevalence of practical knowledge, from the perspective of the Relationship with Knowledge, such as participation in class/year council meetings and the analysis of indicators from large-scale assessments, to the detriment of continuous monitoring. The methodological procedures adopted included document analysis and focus groups. The research was also supported by a mapping of academic productions on school management and teaching, contributing to the construction of the theoretical framework and to the understanding of the state of knowledge on the investigated theme. The data were organized into constellations based on Charlot's theory: (1) Epistemic Dimension: of possession, mastery and self-constitution; (2) Social Dimension: of the social being – my place of speech; and (3) Identity Dimension: of the being that I am – the identity of the subject. The analysis of these dimensions made it possible to understand the knowledge mobilized by the director in pedagogical management, expressed in direct and indirect interventions in the teaching processes. The results show that, although not systematically, the professionals investigated demonstrate commitment to creating favorable conditions for achieving the school's educational objectives. This finding is partly related to the hierarchical structure of the management team promoted by the investigated Department of Education, which favors the distribution of responsibilities and reduces possible gaps in monitoring learning. In light of the Relationship with Knowledge (RcS), it was found that the knowledge mobilized by the managers goes beyond technical skills, involving conceptions of education, professional trajectories, belonging, and positions regarding the concrete working conditions. Thus, pedagogical leadership is built not only by complying with legal prescriptions, but also by the daily construction of meanings and practices focused on the centrality of the teaching and learning process. This research reinforces findings already established in the literature on school management, highlighting that Brazilian school principals face feelings of isolation and intense bureaucratic overload. Furthermore, it indicates that the principal's desire and willingness to monitor learning processes are decisive factors for this monitoring to occur consistently and meaningfully.

This dissertation, titled “Workers Aged 60 and Over: A Study of Work-Related Experiences at a Federal University,” investigates aging in the workplace within the context of a federal institution of higher education, in an environment marked by organizational and technological changes. The study aimed to understand the perceptions, experiences, and challenges faced by technical and administrative staff in education (TAEs) aged 60 or older who are currently employed at the Federal University of Mato Grosso (UFMT), as well as to develop a technological tool designed to promote quality of life at work and support preparation for retirement. This is a qualitative study based on semi-structured interviews with nine TAEs, aged between 59 and 74, representing different occupational profiles, with long institutional careers and varying relationships to retirement. The results were organized into two complementary analytical levels: a thematic axis, structured around the dimensions of the interview guide, and a cross-cutting axis, focused on identifying patterns, tensions, and dynamics that permeate the participants’ daily work lives. The findings indicate a strong sense of belonging and identification with work at UFMT, coexisting with experiences of burnout, institutional pressures, and changes in interpersonal relationships. The digitization of work emerges as an ambivalent experience, perceived simultaneously as a factor in the modernization of routines and as a source of pressure, associated with the need for continuous updating, job insecurity, and the acceleration of work. We also observe an intensification of activities resulting from increased bureaucratization, control, and deadline-related demands, with repercussions on workers’ overload and burnout. The cross-sectional analysis shows that training is perceived as a structural need and that the discontinuity of institutional support measures undermines the processes of adaptation, recognition, and engagement. The results indicate that the experiences of TAEs aged 60 and older at UFMT cannot be explained exclusively by individual or age-related factors, but must be understood in light of the organizational transformations that are reshaping the criteria for valuation, recognition, and job retention in the university context. As a contribution, this study offers an in-depth analysis of the work experiences of TAEs aged 60+ at a federal public university and provides a basis for proposing a technological intervention tool aligned with the needs identified among the study’s participants.

Mining is an ancient activity essential for economic development, but its environmental and social impacts require the implementation of sustainable practices. This project aims to comparatively analyze global voluntary certification frameworks in the mining sector, focusing on the sustainability indicators adopted by certified mining companies. The goal of the research is to examine the indicators of certification standards adopted in mining and the methods used. The research, of a qualitativa nature, will be conducted through a comprehensive literature review and analysis of public audit and sustainability reports from major mining companies, such as Vale, AngloAmerican, among others. Indicators such as water consumption, greenhouse gas emissions, biodiversity impact, and worker health and safety will be compared with criteria established by frameworks like the Initiative for Responsible Mining Assurance (IRMA), the International Council on Mining and Metals (ICMM), and the Global Reporting Initiative (GRI). Expected results include a detailed understanding of the effectiveness of the frameworks, gaps in the indicators, and proposals for improving sustainable practices in the sector. This study could serve as a guide for companies and certifiers, promoting greater environmental and social responsibility in the mining sector.

This study aims to contribute to the understanding of the study activity of female university students at the Federal University of São Carlos (UFSCar), investigating their forms of organization and the meanings produced throughout their academic trajectories. The research recognizes the student as a socially and culturally active subject, whose socio-historical experiences and activities concurrent with studying shape her Social Situation of Development. The discussion encompasses gender inequality within higher education and draws parallels with emancipatory educational practices aimed at social transformation. Methodologically, semi-structured interviews were conducted with undergraduate students from various programs, focusing on Indigenous women, Black and Pardo women, mothers, and LBT+ individuals. The study is grounded in Historical-Cultural Theory, articulating concepts such as study activity, gender, labor, and mediation. The analysis reveals the impacts of material contradictions on the lives of these university women, highlighting difficulties such as the absence of support networks and the confrontation of stereotypes. The results demonstrate that student persistence is mediated by affirmative policies and collective networks, evidencing the need for specific educational policies focused on gender equality and the recognition of female pluralities within the academic environment

Groundwater contributes approximately half of the global domestic water supply, yet the risks of microplastic (MP) contamination in this resource remain poorly understood. This study investigated the characteristics, occurrence, and ecological and human health risks associated with MPs in groundwater intended for human consumption, with emphasis on the Guarani Aquifer System (GAS) in Ribeirão Preto (SP, Brazil). A systematic review of 34 studies (2019–2025) revealed MP concentrations in global aquifers ranging from 0.0003 to 2103 particles/L, with predominance of particles <100 µm, fragments and fibers, and of the polymers polypropylene, polyethylene, and polystyrene. The application of integrated risk indices showed that 69% of the sites presented elevated PLI (Pollution Load Index) levels, 40% high polymeric risk H (Polymer Hazard Index), and 86% extreme PRI (Pollution Risk Index). The estimated daily intake of MPs based on quantity (EDIq) reached 140.2 particles/kg/day for children and 60.09 for adults, evidencing higher child vulnerability. Field investigations in two GAS recharge areas, namely Lagoas do Saibro and Recreio Internacional, revealed mean MP abundances of 20.02 and 7.03 particles/L, respectively, with predominance of fibers and transparent particles <100 µm. The higher concentration recorded at Lagoa do Saibro, compared to Lagoa Recreio, was associated with a 4.7-fold higher population density in the surrounding area of the former. Water samples from tubular wells presented abundances ranging from 0.61 to 3.19 particles/L, a mean of 12 particles/L in public drinking fountains, and 0.67 particles/L in bottled water. Polymeric analysis confirmed predominance of PP, PET, and PE, and the estimated daily intake values were higher for children (up to 2.04 particles/kg/day) than for adults (up to 0.53 particles/kg/day). The research concludes that microplastic (MP) contamination in supply aquifers is spatially heterogeneous, influenced by anthropogenic activities, hydrogeology, and land use. Integrated indices proved more effective than simple MP abundance assessment. Although treatment systems reduce MPs in most cases, sporadic increases indicate particle release from polymeric infrastructures. The study provides unprecedented evidence of MP contamination in groundwater within the Guarani Aquifer System (GAS) area, highlighting the need for standardized monitoring, integrated risk assessment, and protection of groundwater resources.

The struggle for land in Brazil constitutes a historical process marked by territorial disputes, inequalities, and the organization of social movements that seek the right to remain in rural areas. In this context, women have played a crucial role, although they are often made invisible. this dissertation aims to understand how women establish themselves as constituent agents of the territory in the struggle for land, focusing on the Horto Bela Vista Settlement, located in Iperó/SP. The research is based on the understanding that the struggle for land in Brazil is marked by intense land tenure inequalities and intersected by power relations in which gender plays a central role. The methodology articulates archival research, fieldwork, and interviews with women from the settlement. Anchored in the theoretical framework of Agrarian Geography and gender studies, the collected data highlights that, although historically marginalized, women play a fundamental role in the constitution and maintenance of conquered territories, acting politically from the initial encampments to the consolidation of the settlement. The analysis of oral narratives reveals that gender relations in the countryside are still permeated by patriarchal structures, which are nonetheless being challenged by women's everyday practices and resistance. Thus, this research contributes to the debate on territory and the role of women in the struggle for land, highlighting their centrality in this process.

The metro system of São Paulo city is considered essential for urban mobility in the São Paulo metropolitan area and, given the daily volume of riders, the relationship between the system's access points and the urban space where it is inserted becomes an important element for urban planning and a driver of public policies. This study applies the Node-Place methodology, with adaptations, to evaluate the metro stations of São Paulo's urban rail system according to their connectivity with the public transport network, their functionality within the urban space, and their accessibility via different active transport modes. The results were also analyzed in relation to the sociodemographic profile of the population surrounding the areas of each station. The research is structured based on a bibliographic and bibliometric review that identifies the main indicators used in similar studies, which are organized into three categories: Node (connectivity), Place (land use), and Active Mobility (accessibility via active modes). An adaptation of the Analytic Hierarchy Process (AHP) was applied to weight the indicators based on their frequency in the literature and to calculate final scores for each category. Data were collected from official sources and analyzed using geoprocessing techniques, allowing for the analysis of all stations in the city’s metro network. Preliminary results reveal spatial inequalities among the stations, with higher performance in those located in central areas of the city, such as Sé, República, and Anhangabaú stations, which showed a high level of connectivity, diverse land use, and favorable conditions for active mobility, alongside a concentration of high-income and working age population. On the other hand, stations located at the edges of the network, such as Capão Redondo, Vila Sônia, and Campo Limpo, performed lower and presented a surrounding population more dependent on the quality of public transport infrastructure, including children, elderly and women, highlighting challenges in urban integration and the redevelopment potential of these areas. The methodology applied to the São Paulo context enables the identification of opportunities for intervention and territorial improvement, contributing to the strengthening of the public transport system and to more equitable, efficient urban planning aligned with the principles of Transit-Oriented Development (TOD).

Photodynamic therapy (PDT) is an emerging strategy for cancer treatment and represents a promising approach for melanoma, one of the most aggressive and therapy-resistant forms of skin cancer. In this study, meso-tetra(4-pyridyl)porphyrin complexes coordinated with palladium(II)/diphosphine ligands (Porf@dppe, Porf@dppp, Porf@dppb, and Porf@dppf; dppe = 1,2-bis(diphenylphosphino)ethane, dppp = 1,3-bis(diphenylphosphino) propane, dppb = 1,4-bis(diphenylphosphino)butane, and dppf = 1,1′-bis(diphenylphosphino)ferrocene), previously shown to display favorable lipophilicity and efficient singlet oxygen production, were evaluated againsthuman (A375) and murine (B16–F10) melanoma cells, as well as non-cancerous keratinocytes (HaCaT). Cytotoxicity measured after a 90 min incubation period yielded dark IC50 values between 0.6 and 8.6 μM, whereas light irradiation (λ = 415 nm, 1.8 J cm􀀀 2, 36 mW cm􀀀 2) resulted in markedly lower IC50 values in the nanomolar range (2–27 nM). Irradiation increased intracellular ROS levels, induced morphological alterations in A375 cells, inhibited long-term proliferation, and reduced cell migration, particularly for Porf@dppb and Porf@dppf. The highest cytotoxicity was observed for Porf@dppf, likely due to the redox-active ferrocene unit promoting Fentontype reactions and enhanced hydroxyl radical formation. Electron paramagnetic resonance (EPR) spin-trapping experiments confirmed light-induced generation of hydroxyl radicals and superoxide anion, with significantly higher hydroxyl radical production observed for Porf@dppf. The photodynamic activity of these complexes is attributed to efficient ROS production involving simultaneous contributions from both Type I and Type II mechanisms. Moderate binding to bovine serum albumin suggests possible albumin-mediated plasma transport. Overall, palladium(II)/diphosphine porphyrin complexes emerge as promising photosensitizers for melanoma photodynamic therapy.
