This course completion project presents a reflective qualitative review of the state of the art in depression treatment and its application to the subjective self. The review delves into the pathophysiology of depression, pharmacological strategies to expedite antidepressant response, and enhance antidepressant efficacy, including medication switching, combination of antidepressants, and co-administration of augmenting agents. It also discusses ketamine, an agent that produces an immediate and effective response in treating suicidal behavior, and the involvement of the nociceptive system in the pathophysiology of depression. The review introduces a paradigm describing the possibility of simultaneous action in three therapeutic response time frames in depression treatment: immediate, rapid, and slow. It discusses pharmacological agents with their respective properties. Furthermore, it emphasizes the importance of maximizing pharmacological therapeutic effects and remission rates, extending beyond cognitive, behavioral, or discursive strategies. The review analyzes the real impact of such optimizations on the author throughout their personal and academic experience. This review concludes that ketamine, an agent providing an immediate and effective response in treating suicidal behavior, could be a crucial factor in reducing the impact of depression on society, altering outcomes such as suicide and loss of functionality.

This work describes the itinerary of a PCD student on the Medicine program at the Federal University of São Carlos during the period from 2018 and 2023. Its purpose is to present a personal perspective on the stages experienced within the scope of medical training. In this sense, the academic trajectory experienced is narrated in chronological order, describing the experiences of yet another young PCD student inserted in a unique pedagogical sphere that constitutes the medical course structured by the active PBL (Problem Based Learning) methodology, in the city of São Carlos, in the interior of São Paulo, Brazil. In the text, educational cycles are examined, which represent the milestones of demonstrating involvement. It is noteworthy that in this work the entire set of critical-reflective analysis expressed here takes place from the insurmountable perspective of a student with a physical disability during the pandemic of COVID-19 that ravaged the globe throughout most of the school periods. Finally, some paradigms of medical education are problematized in light of a universe of education — more than ever — dynamic, hyperconnected and, more recently, with innovative artificial intelligence and big data technologies at our disposal.

Water is a fundamental resource in environmental, ecological, economic, and political terms, and as its demand has increased, the human relationship with water has shifted to a purely utilitarian view. However, it is possible to go beyond the associations between man and water, which include social and cultural links that have been forgotten, among which the relationship between women and water is present but still little valued. There are notable gender asymmetries in control, access, and use of resources, as well as greater male participation in public and decision-making positions in water management. Given the important role that women play in water management and conservation, it was necessary to look at their relationships and women's perceptions of water, questioning the inequalities related to water resources in Brazil. Therefore, this research aimed to explore, identify, and analyze women's different relationships with rivers and springs, as well as women's perspectives on better water management and conservation. To this end, a systematic bibliographic review was conducted, as well as case studies with 12 female protagonists involved with water, rivers, and springs, through the application of interviews, and the content analysis method was used to analyze the results. The results showed that women have different knowledge and valuable visions related to water for the management and conservation of this resource. These varieties refer to the context in which the protagonists are situated, as well as their life experiences and the direct nature of their relationship with water. However, the current scenario still shows a discrepancy in the unequal participation of women in the management of water resources, in different areas, contexts, levels of control, and access, when it comes to the relationship that both genders have with water. Incorporating a gender perspective aims to include the participation and empowerment of women in all stages of decision-making, with a view to alternatives to reduce these asymmetries. The aim is to achieve greater involvement of women (contributing to social balance) in water management and conservation processes, enabling and promoting gender equality and its relationship with water management.

This project analyzes how non-formal environmental education has contributed to formal environmental education in schools. The object of study focuses on the project Learning wit the Atlantic Forest, with activities to milieu analysis, being developed by the SOS Mata Atlântica Foudation since 2010 at the Forestry Research Center SOS Mata Atlântica - HEIENKEN Group, located in Itu, São Paulo. The time frame of the research is limited to the year 2022, with 11 teachers from 6 schools as subjects. This is a case study and the methodological data collection procedures involve bibliographic and documentary review and fieldwork in an action research approach. The results obtained indicate the relevance of studying the environment in the educational training of students and teachers regarding environmental education and, therefore, the potential of non-formal educational spaces such as the Experiment Center in this context. It is concluded, with this work, that the Learning with the Atlantic Forest project has interfaces with the milieu analysis, is recognized by teachers about the educational potential and encourages developments for actions at school, in order to highlight and strengthen the positive relationship and proposal between formal and non-formal environmental education.

This study was carried out with the general aim of analyzing the history of Professional and Technological Education (EPT) in Brazil, from the colony to the 2000s, from the perspective of polytechnic training, in order to understand how professional education institutions were organized throughout history, what their pedagogical-social conceptions and functions were in the face of current national policy, as well as the contradictions inherent in the process of professionalizing the Brazilian working class. The research was limited to the historical period between colonial Brazil and the end of Luiz Inácio Lula da Silva's second administration. Developed from a qualitative approach, it was configured as bibliographical research, which, in a chronological narrative, described and analyzed the periods of the historical framework considered. The data revealed that over the centuries, Brazilian vocational education has been a space for conforming and submitting the lower classes to socio-economic interests and has been managed by the elites, with a depoliticizing and instrumentalizing function. Before the enactment of Law 11.982/2008, vocational and technological education was (in this order of occurrence): affiliated with hygienist conceptions; configured as an educational institution - houses of welcome, benevolence, correction; compulsory; and linked to the technicist paradigm. Following the enactment of the aforementioned law, the possibility of a polytechnic education for vocational and technological education students was introduced, with a view to building autonomy and awareness of the role they can play in society. The research enabled us to compare the history of EFA and its underlying concepts with the key concepts of polytechnics and work, understood from a Marxian and Gramscian perspective. The results showed that EFA, throughout the history of Brazilian education, has been directly linked to social class interests and capitalist development in Brazil. Furthermore, even though it has been updated over time, it has remained based on the concept of class domination and directly linked to social and racial prejudices. Movements to expand school levels and the conceptions of these institutions were linked to capitalist needs at the various stages of their development. Whether deliberately or not, governments have not confronted this problem, which has meant that the concept of polytechnics has not been effectively integrated into vocational and technological education in Brazil, at least until the historical limit considered in this research.

The study of structural masonry under high temperatures is still initial in Brazil. Even internationally, little is known about the thermal and mechanical properties of masonry components when overheated. In the absence of a specific Brazilian standard, foreign guidelines are adopted by the technical community to check structural masonry in fire situations. However, its applicability is questionable, given that Brazilian materials have different characteristics of geometry and composition, in addition to the associated construction practices. Despite these differences, most international design/verification procedures are based on full-scale wall tests which, due to the lack of conveniently equipped laboratories, are not yet viable in our country. Therefore, a more feasible approach would be the correlation between test results, under high temperatures, of smaller models (blocks, prisms, small walls) and larger models (full-size walls), like what is done at room temperature. For that matter, this research aimed to determine the residual mechanical behavior of laying mortars, grouts, and prisms with two concrete blocks. There is no national, or even international, procedure for assessments of this nature in structural masonry prisms. The method used corresponded to an adaptation of that proposed by Medeiros, Parsekian and Moreno Jr. (2022) for the use of RILEM TC 200-HTC:2007 curves in structural concrete blocks. Were produced mortars with lime (conventional), lime-free (industrialized) and from three resistance classes (5, 10 and 20 MPa); grouts with 15, 25 and 35 MPa; prisms with two hollow and uncoated concrete blocks, varying block strength (6, 12, and 24 MPa), composition and strength of the laying mortar. All materials were subjected to low heating rates (4°C/min for mortars and 1°C/min for others) until they reached 200, 400, 600 and 800°C; kept for one hour at the respective temperatures; and cooled at the same rates to temperatures close to ambient. After cooling, the residual values of compressive strength and secant deformation modulus were obtained via destructive tests. The results showed that lime significantly interfered with the degradation of the mortars, especially after 400°C. The rehydration of the binder led to expansion, cracking, and greater reductions in the ordinary mixtures. Even with small amounts of lime, the grouts exhibited behavior consistent with residual normative curves for ordinary concretes (ACI/TMS 216-1:2014, EN 1992-1-2: Eurocode2: 2004) and those extracted from the literature. The confinement of the mortar joint led to a delay in the degradation of the prisms' mechanical properties. The cracking observed in the mortar specimens did not occur in the prism joints, regardless of the type of mortar and exposure temperature. The prism results were consistent with those of the blocks tested by Medeiros (2022). For all the materials tested, the drying modulus decreased early compared to the compressive strength. After 800°C, the property value became negligible. As a contribution, normalized mechanical property degradation curves were proposed for each material investigated.

The insertion of the librarian in the health context is increasingly necessary, not only to train users who are experts in health regarding the sources to be consulted, but in the guidance and delivery of reliable information, filtering, treating and also certifying the veracity of information that will be disseminated to end users. In this sense, the question arises what is the professional profile and working conditions of librarians who work in teaching hospitals in the Central-West region of Brazil? Therefore, we seek to present an overview of the professional profile and respective working conditions of clinical librarians working in teaching hospitals in the Central-West region of Brazil. This is an exploratory and descriptive study. As methodological procedures, bibliographical surveys were carried out using the bases of the Information Science Database (BRAPCI), Brazilian Digital Library of Theses and Dissertations (BDTD), Scientific Electronic Library Online (SciELO – Brazil), ENANCIB Annals and Portal de Capes periodicals. To collect data, we used a semi-structured questionnaire that was prepared via Google Forms, with a total of 20 questions, all anonymous and freely chosen in order to avoid bias in the answers. The results demonstrate that the majority of the 11 respondents identify themselves as information librarians and that the main difficulties in this niche of professional activity are related to the difficulty in understanding technical language; use appropriate information technology to organize and disseminate information; assess information needs in order to meet identified needs; master the sources of information in the area; carry out specializations and/or training; develop and manage information services and; provide support and training for users of the library or information service. In conclusion, the work of health librarians in the Central-West region is still incipient, and it is opportune to increase the supply of courses and specific training that trains librarian professionals who wish to work in the health context and in clinical environments.

Excessive pesticide use results in water pollution that is treated for human consumption. Data from the VIGIÁGUA system, available in SISÁGUA, are useful in assisting Health Surveillance agencies in managing health risks associated with treated water. This study aimed to investigate the states that use pesticides the most, such as Mato Grosso, São Paulo, Paraná, Rio Grande do Sul, Goiás, and Minas Gerais, and the action plans or contingency plans to monitor pesticides in water intended for human consumption. The objective was to assess the monitoring of pesticides in water and identify gaps and potential improvements. Data for this exploratory study were collected from sources such as IBAMA, the Ministry of Health (MS), the Capes Periodicals Portal, and Scielo, as well as scientific articles and book chapters. Document analysis were conducted on the IBAMA and MS websites, reviewing spreadsheets with information on pesticides and water quality. The analysis period was from 2014 to 2021, during which pesticide levels in the water of states with the highest consumption were examined. In all states, there is quantification of values above or within the Maximum Permitted Value for the pesticide parameter. Health Surveillance agencies analyze these values individually, as the Ordinance 888/2021 does not establish a maximum limit for the total quantity of compounds in the water, only for each parameter. In some cities, the situation is more critical, as mentioned in the text, and in some states, the number of analyses conducted is insufficient, masking the true situation of the municipality. It was concluded that the actions of Health Surveillance agencies do not adequately consider chronic and multiple exposure to pesticides in water and that there is no uniformity in actions.

The study addresses novelty detection in data streams, emphasizing the significance of this task in high-volume and high-velocity information environments. It proposes substantial improvements to the EFuzzCND algorithm, leading to the development of EIFuzzCND. These enhancements encompass an incremental approach, a reduction in dependence on true labels, and the implementation of the Incremental Confusion Matrix. Experiments validate the efficacy of EIFuzzCND across diverse scenarios, and result analysis underscores its capability to handle specific challenges, such as sudden concept shifts. The work contributes to advancing novelty detection in data streams by providing an innovative and practical approach, concluding with recommendations for future research.

The approach of statistical methods capable of accurately predicting the relationship between structure and reactivity represents a major impact on the development of reactions. Recently, machine learning tools have been guided and applied in synthesis design. In the context of the work described here, these methods provide rapid information and relevant estimates about the structure and respective activity of substrates that are summarized in structural descriptors that influence the desired activity. Here we list the main results obtained in the development and use of substrate parameterization in new methodologies. In the context of nucleopalladation reactions, we highlight Wacker-type reactions that employ carbonylation reactions of non-activated double bonds by CO capture in a palladium- catalyzed process. We present two new methodologies, one of them to obtain pyrazoline ester derivatives tolerant to different substitutions in strategic positions of the starting material as demonstrated by the scoping study. As well, a new methodology for obtaining pyrazolines with a ketone moiety using boronic acids which allowed access to structural diversity ketone derivatives not previously described guided by a virtual library of boronic acids. Analysis of the electronic and steric factors into the reactivity was fundamental for understanding the nucleophilicity necessary for boronic acids in the transmetalation step. In sequence, we report our efforts to integrate data science and computational chemistry tools to guide, predict and explain the reactivity of persistent radicals generated in the reduction of cyano-arenes in the electrophilic cross-coupling between cyano(hetero)arenes and alkyl halides. The selection of substrates was made from the construction of a virtual library of cyanoarenes via projection of the chemical space by UMAP based on the dimensionality reduction of DFT level physicochemical parameters, ensuring structural diversity in relation to the chemical space. A predictive univariate model could be generated by correlating an electronic parameter with yield.

In repairable systems, the failure process defined by the failure intensity function can be impacted by three crucial characteristics: the type of repair performed after the failures occur, the underlying cause of the failure (competing risks) and the presence of unobservable factors acting on each failure time or on the system as a whole (unobserved heterogeneity). In particular, unobserved heterogeneity can be modeled by frailty models, well known in the reliability literature. However, the majority of existing studies in this domain assume only minimal repairs after failures, which is a highly restrictive assumption and not always applicable. There is, therefore, a theoretical gap to be explored encompassing frailty models that consider systems subject to both perfect and imperfect repairs and still subject to competing risks. The primary objective of this work is to present new parametric univariate and shared frailty models for multiple repairable systems, considering different types of repairs and a competing risks framework. These proposed models extend and generalize those already existing in the literature, as they account for perfect repairs and all possible failure memories within both the ARA$_m$ and ARI$_m$ classes of imperfect repairs. In this sense, they are models capable of simultaneously identifying the effect of the repairs actions and the presence of unobserved heterogeneity among failure times or among the systems under analysis. This characteristic holds substantial relevance in real-world situations, as a deeper understanding of the system's failure process can lead to improved preventive maintenance policies and reduced repair-related costs. In all proposed models, we assume that the initial failure intensity follows a Power Law Process and that the parametric frailty terms associated with failure times or systems follow a Gamma distribution. We employ a frequentist approach to construct the likelihood function for each model and suggest numerical methods for obtaining maximum likelihood estimators and their corresponding asymptotic confidence intervals. Additionally, we propose the use of Bayesian methodologies based on Markov Chain Monte Carlo algorithms as an alternative to the frequentist method. Simulation studies are conducted for each proposed model, and, finally, the methods presented are applied to real datasets.

Health has always been an extremely researched topic in various fields of knowledge. Among them, Geography of Health has sought to work on the relationship of health with the environment. This research follows the same line, as it sought to understand the distribution of hospitals by place of residence in the small towns of the Regional Department of Health of Sorocaba (DRS) and to compare them with the territory uses existing in these cities. The work was based mainly on the concept of territory used. In the analysis of the 35 small cities that fall within the present proposal, it was found that those included in the Sorocaba Metropolitan Region have greater influence on the industrial dynamics and have lower rates of internment. By contrast, cities that are not in the metropolitan dynamics have been characterized by a dynamic of the uses of the territory focused on the area of services and in the field of agricultural production and lead the ranking in the number of hospitals.

Forests in the Atlantic Forest biome are increasingly rare, due to some degration factors that affect forest areas, such as, the uncontrolled urban areas expansion, agricultural and industrial activities, illegal deforestation, animal trafficking and the introduction of exotic species. One of the strategies to reduce the effects of fragmentation, increase the availability of resources and maintain ecological processes is to increase landscape connectivity through recovery actions, aiming to facilitate the flow of organisms among the remnants. Thus, the present study aims to plan the landscape in order to support the implementation of an ecological corridor among the two largest forest remnants of the Municipality of Campinas, the Area of Relevant Ecological Interest Mata de Santa Genebra and the Mata do Ribeirão Cachoeira. Land cover and usage mapping was carried out through visual interpretation of satellite images at a scale of 1:5.000, with the survey being carried out at a scale of 1:2,500, which resulted in a classification of 18 use classes. The species Puma concolor (cougar) was chosen as the target species for developing a connectivity scenario. To construct the corridor proposal, a buffer of 50 meters was created on each side of the chosen connectivity lines, totalizing 100 meters in width. The proposed corridor has an area of 248.86 ha, and taking into consideration the area of the priority remnants that are connected by it, the area adds up to a total of 1.783,49 ha. Validation of the corridor was carried out using trap cameras installed at 5 points along the proposed corridor, with the main species recorded being Puma concolor, Cuniculus paca and Caluromys philander.

This work starts from the foundation that there are educational processes in religious discourse. In this way, we consider that teaching and learning are made possible by rituals, actions, symbolization and meanings of identity, cultural and historical-social processes that permeate literary discursivity. Also, that religious discursive formations are organized and are present in literary discursivity, constituting meanings in the movements in and of history, in the composition of the subjects of the discourse and their identities. Therefore, the purpose of this study is to analyze, through subjectivation and objectification practices, the subjectivities that involve the voices that emerge in the religious discourse of African origin in the works Jubiabá, Mar morto and Tenda dos Milagres, by Jorge Amado, specifically in the terreiros de Candomblé and places of residence of the characters described in the mentioned works. To do so, we adopted discourse analysis procedures from the Foucaultian perspective, featuring a qualitative methodology, based on a proposal by Rosa Maria Bueno Fisher, through our analyses, we were able to verify that the silencing and subjectivities produced in the communities described are marks of historicity that flow and underline resistances and struggles that preserve values and demarcate ethnic, cultural statements, manifestations of faith and belonging of the subjects characters of the Amado’s literary works, starting from four different perspectives: educational processes, socialpolitical, female profiles and religiosity.

The various obstacles imposed on the implementation of the inclusive education have made its effective implementation impossible. As a thesis, I assume that the subjecting violence manifests itself in the inclusive context, through normative logic, activated in the classification and categorization of disabled bodies and their affections. This movement weakens plural forms of life and, therewith, to maintain singularities, some bodies rise up, establishing resistance through lines of flight. In this sense, I aimed to map the practices of (non) violence in inclusive education composed of molar, molecular and lines of flight that act in the production of subjective marks in the deaf ethos. This is a cartographic research, based on a paradigmatic case, carried out in a school unit located in the interior of the state of São Paulo, in the high school stage. In school cartography, I problematized the practices of deaf subjectivation arising from the relations of knowledge and power produced in school discursive practices. I turned to the internal and capillary productions of/in the school, through the eyes of the deaf person, as well as about their insertion in inclusive educational practices. The field research took place on two fronts: observations in the school territory, with entries in a field diary and an interview, as a cartographic procedure. We opted for a cartographic analysis, conceptually based on the philosophies of difference. The theoretical reference came from Michel Foucault, Gilles Deleuze, and Félix Guattari. Were identified, interspersed with the narrative of the life poem, four molar lines (linguistic, physical space, affective and symbolic-religious violence) and four molecular lines (non-violence of the encounter, of being queer, of being umbandista, and other deafness), which guided the discussions. It is believed that the research contributes to recognizing aspects that lead to violence and non-violence in the constitution of subjectivity during the school trajectory of deaf people. In view of the signs found, there is a way of existence, a pragmatic of singularity in the life-poem, and that their voices/experiences in common rooms and the inclusive school stand as local knowledge that resists and announces more ethical practices in favor of differences made along lines of flight.

This thesis addresses the development of a composite of green high-density polyethylene (G-HDPE) and hydroxyapatite (HA), compatibilized with high-density polyethylene functionalized with maleic anhydride (HDPE-g-MAH). It further explores the hybridization of this nanocomposite onto a Ti6Al4V - ELI alloy through injection overmolding, focusing on biomedical applications. The study involved the synthesis (precipitation in aqueous medium) and characterization (XRD, XRF, particle size distribution, and SEM) of hydroxyapatite, extrusion and injection molding, mechanical (tensile and impact), thermal (DSC), microscopical (SEM), and in vitro biological characterization of the composites. The results were evaluated using design of experiments (DOE), analysis of variance (ANOVA), and Tukey test. The composite containing 30 wt% of HA and 30 wt% of HDPE-g-MAH (relative to the HA content in the composite) showed a good balance of mechanical properties, nearly negligible hemolysis percentage, and a mass increase of 8% during the hydrolytic degradation test. The hybrid joint of the composite with the optimized composition, injection molded onto Ti6Al4V, showed good interfacial anchoring, resulting in outstanding shear strength (3 MPa) and fatigue life (> 106 cycles). This multi-material approach has provided subsidies for the advanced manufacture of biomedical devices with optimized mechanical and biological properties, exploiting efficient processing techniques.

Brazil stands out for its high production of sugarcane. This production generates a significant amount of byproducts, such as sugarcane straw. Due to its high cellulose content, converting straw into nanocellulose can be a promising alternative to add value to such a side-stream. Recent studies have shown that producing nanocellulose with residual lignin is a sustainable alternative to modify its surface properties. Residual lignin reduces the hydrophilicity of the nanocellulose, improves its compatibility with hydrophobic polymers and increases its thermal stability. Given the growing interest in the study of lignin-containing nanocellulose (L-NC) and the possibility of using sugarcane byproducts for this purpose, this work aimed to obtain L-NC from sugarcane straw with different residual lignin contents to investigate the effect of lignin on the thermal, morphological, surface, and structural properties of nanocellulose. The lignin content in the straws was varied by bleaching with chlorine dioxide under two conditions of reaction time and amount of bleaching chemicals. Three types of L-NC were produced using sulfuric acid hydrolysis from three biomass samples, namely: unbleached straw (U), mildly bleached straw (MB), and severely bleached straw (SB). The resulting lignin contents were 17.3 ± 0.3% for US, 14.7 ± 0.3% for MB, and 4.6 ± 0.8% for SB. Higher yields were observed for the L-NC obtained from bleached straws, which are purer in terms of cellulose. Atomic force microscopy confirmed the isolation of cellulose nanocrystals and nanofibers, regardless of the bleaching severity. Finally, lignin was found to increase the thermal stability of nanocellulose while reducing its crystallinity index, and colloidal stability. Its width and hydrophilicity did not vary significantly.

Cryptourrencies are decentralized digital currencies created with the intent of replacing traditional forms of payment. Their high volatility is one of the aspects that causes distrust among investors. Artificial Intelligence based on Machine Learning algorithms can be an invaluable tool to analyse this characteristic, helping to predict prices. In this sense, this project’s goal is to use algorithms implemented in Python — Support Vector Machine and Long Short-Term memory — alongside convenient performance metrics such as mean squared error, mean absolute error, maximum error and R^2 to assess their price prediction capabilities in face of such randomness.
