This master's research aimed to analyze the narratives of three women who graduated from EJA (Portuguese acronym for Youth and Adult Education) and what were the transforming elements and the excluding elements that influenced the insertion of these women in higher education, having Dialogical Learning (1997) as a theoretical-methodological foundation, based on some central authors such as Flecha (1997); Freire (1985; 1997; 2005; 2009; 2011; 2014), following the dual perspective described by Giddens (1991; 1996; 2003). This is a qualitative field research based on twelve narratives of three women who graduated from EJA, who have already concluded higher education in Pedagogy in Brazilian federal public institutions. Due to the Covid-19 pandemic, the narratives were virtually collected based on the Life Stories methodology guidelines (JOSSO, 2004) and analyzed based on the contributions of the Communicative Methodology (GÓMEZ et al, 2006). The narratives present excluding elements and transforming elements, both in the school trajectory and in the social environment of the three women with regard to influences in the their journey towards a higher education degree. As excluding elements, the data revealed the denial of the right of access to and permanence in school spaces, the presence of male chauvinism as a consequence of men's domination over women and the female role in the patriarchal and capitalist society in which we live. As transforming elements, the data put in evidence the instrumental dimensions, such as a gain in autonomy and critical thinking, highlighting the role of the progressive teacher (FREIRE, 2009), in addition to solidary relationships in building support networks for women. It is expected that those discussions contribute towards the role of this progressive teacher and solidary relationships in the fight against male chauvinism and ageism, helping with new public policies for this modality of education, which is marked by a historical context of exclusion and a current situation that still needs transforming instruments so that new EJA graduates are also included in the university environment, as a right.

Periodization in sports training is always questioned, as well as the effects on the individual on the physical aspects represented by anthropometric and hemodynamic capabilities. In particular, the behavior of intracranial pressure has been shown to be a vital new variable for brain functioning and still little elucidated in the field of training. Thus, the present study aimed to evaluate the effects of a periodization of physical training with professional athletes in the modalities of men's soccer, futsal and women's volleyball during 10 weeks in three stages pre-season (v0), after 5 weeks (v1) and after 10 weeks (v2). For this, anthropometric, hemodynamic and physical tests were performed. As for the anthropometric variables, BMI and %F, the three modalities had an evolution, that is, a reduction in the values, in the scope of the physical capacities there was also a significant improvement over the 10 weeks highlighting the increase in VO2max., increase in potency of the vertical jump and reduction in the time of the agility test. As for the hemodynamic variables, in addition to the reduction in BP, it was possible to verify a reduction in the values of ICP and HRV, with a relationship of greater action of the parasympathetic system in relation to the sympathetic one. Therefore, we conclude that the effect of periodization was positive for the 3 modalities, in addition to promoting a change in ICP pressure values and actions of sympathetic and parasympathetic activities.

Psychological verbs (such as shake, afflict, and thrill) denote a feeling or emotional state in the experiencer, the experiencer being necessarily human. This research describes the phenomenon of constructions with psychological verbs in Portuguese and presents a contrastive analysis of studies on the classification of these constructions carried out for Brazilian Portuguese (CANÇADO, 1995; CANÇADO et al., 2017[2013]) and European Portuguese (MACEDO OLIVEIRA, 1984; MENDES, 2004; BAPTISTA AND MAMEDE, 2020). Thus, it will be possible to identify the points of intersection and divergence between these two variants of the Portuguese language. For this, the theoretical-methodological model used is the Lexicon Grammar (GROSS, 1975), which establishes principles of description and systematic classification of the predicative elements of languages, based on Distributionalism and Transformational Theory of Zellig Harris (1961; 1964). From the data described here, it is expected to contribute to the linguistic description of the phenomenon of constructions with psychological verbs, as well as to the development of linguistic resources that can be used in different didactic applications and in Natural Language Processing (NLP).

This master's dissertation starts from the cross-analysis between the epistemology of political and difference theory and classifies nationalism (ANDERSON, 2008; HOBSBAWM, 1990) as a phenomenon that implies the crisis of non-hegemonic identities (DUBAR, 2009; APPIAH, 2018). It selected homoaffetivity as one of these excluded identities and conceptualizes the crisis of these identities in the face of the novels Enquanto os dentes (2017), Carlos Eduardo Pereira's, and Todos nós adorávamos caubóis (2013), Carol Bensimon's. Split into two theoretical and one analytical chapter, this dissertation begins with the conceptualization of nationalism and the construction of national states (ANDERSON, 2008; HOBSBAWM, 1990; HALL, 2006; CANCLINI, 2015). Following those principles, it was applied to the Brazillian reality in the face of its consolidation as a national state, with their reflections in the literature (SANTIAGO, 2019 a, 2019 b; CANDIDO, 2006, 2000; SCHWARZ, 2014, 1987; SUSSEKIND, 2005; DALCASTAGNÈ, 2002). In chapter two, this dissertation approaches the constructions of the epistemology of differences (CONNEL, 2012, 2020; HALL, 2017) and the underpinnings of what are considered conflicting identity crises (APPIAH, 2018; HALL, 2014). At the end of the theoretical analysis, it is possible to understand the conceptions of power and the places that homoafetive identities occupy (BUTLER e SPIVAK, 2020; BUTLER, 2017). After finalizing the punctuation of the conditions of homoafetive literature in the contemporary Brazilian scenario (POLESSO, 2018; DALCASTAGNÈ, 2012), under which it is argued that identity constitutions depart from moralistic demands of the social body and the intellectuality, intercedes in the analysis of the objects. In this sense, it was established that other discursive devices question the literary canon and reflect the place that homo-affective people occupy in Brazilian society. From this, the dissertation concludes that the identities of the protagonists Antônio, Cora, and Julia, are the results of this exploration and lie alongside the homogenizing and discriminatory character of the ideological rhetoric that structures the Brazilian nation-states. That is, this work demonstrates how the state apparatuses and their segregative ideologies are oriented towards domination and normalization of homo-affective bodies.

Currently, widely used in zoos and aquariums, in addition to being adopted in vivariums, environmental enrichment aims to allow the captive animal to express its species-specific behavior, improving its quality of life. Maternal care is intrinsic to emotionality, as a female to satisfactorily care for her offspring needs to be in excellent physical and emotional condition. When we think about mammals, it is known that maternal care has complex genetic bases and is susceptible to interference from environmental factors. Result of the individual-environment interaction, epigenetics comprises molecular changes in DNA and histone proteins, which are likely to be inherited, do not modify the DNA sequence and may undergo reversibility. This study aimed to verify the influence of environmental enrichment in a transgenerational way in females of Mus musculus LG/J on aspects of emotionality and maternal care. The females studied were divided into four groups and had never been exposed to environmental enrichment, namely: female daughters of mothers who were exposed to environmental enrichment from the pubertal to maternal stage, female daughters of mothers who were never exposed to environmental enrichment, female daughters from mothers who were submitted to environmental enrichment in the maternal phase and females daughters of mothers who were exposed to environmental enrichment only in the maternal phase. Emotionality was analyzed using open field, elevated plus maze and forced swimming tests. Maternal care was analyzed by the mother's postures in building a nest, performing placentophagy, offering milk to the young, having aggressive behavior against intruders and maintaining the size of the born litter. The results showed that phenotypically, the influences of environmental enrichment on emotionality and maternal care were not inherited, with females from non-enriched mothers having greater reproductive success and a lower rate of anxiety. The study showed that in this case, environmental enrichment must be applied continuously, so if a generation has been enriched, the offspring cannot be deprived of such a mechanism that aims to improve animal welfare.

Industrial activity is one of the main responsible for environmental, social, and economic impacts, which leads industries to seek new ways to manage their processes. In this scenario, Lean has become a strong ally of the industrial sector since the application of the Lean socio-technical system can improve sustainability performance. In addition, the sector is undergoing important technological changes amid Industry 4.0 (I4.0) and understanding how these approaches interact is of great interest to academics and practitioners. Therefore, this research is dedicated to identifying and proposing ways to integrate Lean and I4.0 and analyze the effect of these relationships on sustainability performance. For this, two Systematic Literature Reviews (SLR) were conducted. The first aimed at analyzing the integration between the three themes, Lean, Sustainability, and I4.0, and the second shows the relationship between Lean and I4.0 to support sustainability. The second analysis aims to deepen how relationships and support can take place, which was strengthened by cases study. The results show that the industries can benefit from the integration between Industry 4.0 Technologies (I4T) and Lean Practices (LP) to exploit the technological and human potential and support the operational system in improving sustainability measures. The initial evidence suggests a greater potential for integration between I4T such as the Internet of Things (IoT) and Big Data Analytics (BDA), with Lean Technical Practices (LTP) such as Total Preventive Maintenance (TPM) and Just-in-Time (JIT), and Lean Social Practices (LSP) such as Continuous Improvement, Customer Involvement, and Supplier Partnership. In this sense, Economic Performance indicators are the most favored, with little evidence in the literature of improvements in environmental and social performance indicators resulting from the integration between I4T and LP. The cases study confirm the findings of the literature and add evidence of how the main support relationships occur in an industrial environment, in addition to addressing negative aspects of integration. The results of the literature guided the construction of a model conceptual model tested through survey research with the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique. The survey research was developed to assess the direct and indirect effects of Big Data Analytics Capabilities (BDAC) on economic, environmental, and social performance, in the presence of Lean Socio-Technical Practices as mediating variables. The results confirm the direct influence of BDAC on Social Performance and identify Lean Technical Practices as significant mediating variables that act as a catalyst to boost the indirect impacts of BDAC on Economic Performance. This comprehensive research can help researchers and practitioners fully understand and benefit from the integration of I4T, particularly BDAC, with the LP while managing sustainability issues.

The present research sought to understand, considering the centrality of human labour for the psyche and the phenomenon of the precariousness of contemporary working conditions, the contents and psychosocial strategies that constitute the social representations about the work of workwoman who provide services to an outsourced cleaning company within a university campus. In order to do so, we analyzed their occupation trajectories, sociodemographic categories, collective identities, interpersonal relationships and, above all, their understanding of the contradictions lodged in their productive activities. After conducting semi-structured interviews and the subsequent confrontation of the reports with critical theoretical- methodological references, we were able to have access to a myriad of meanings related to a complex work reality. Such social representations revealed the dialectic relations of oppression and emancipation, of empathy and hostility, of companionship and invisibility, of solidarity and competitiveness that coexisted within the outsourced cleaning job and, above all, in the subjective constitution of the precariat.

This work describes a scientometric study and a bibliographic survey on the supplementation of fish feeding aimed at fish farming. Supplementation is based on the use of animal, vegetable and yeasts, and focuses on the use of Chironomidae larvae. For this study, bibliometric indicators were selected, which are classified into quantitative and impact. The main works that carried out research with supplementation in fish feeding were selected, aiming to identify the points already studied and the points that still need to be explored. With this study, it will be possible to enrich fish farming practices at the local, regional and global levels, promoting cost reduction and increased sustainability, seeking alternatives for the nutritional enrichment of the feed used. However, it was found that the use of natural protein sources can improve performance in the development of fish, however, it is necessary to carry out more studies in this area

Global food security is one of the biggest challenges we face today, and to this end, establishing sustainable strategies towards the development of more efficient and safer agricultural products is indispensable. Sulfur (S) plays an important agronomic role for crops as a secondary macronutrient, and its deficiency in agricultural soils has become an increasing problem for crop productivity and quality. Elemental sulfur (S8) is an abundant byproduct of petroleum refining that stands out as a S-fertilizer. However, S8 can only be assimilated by plants after oxidation by soil microorganisms to sulfate, a slow process that restricts its agronomic efficiency, especially when applied as pellets. Aiming to optimize this conversion, we recently investigated the transformation of the stable S8 structure into a new material with linear S chains using the polymerization technique of inverse vulcanization. The polysulfides (PolyS) showed superior oxidation rates to S8, in addition to interesting processing and conformation characteristics, ideal for the incorporation of other fertilizers. Thus, the primary goal of this work was to evaluate the potential of PolyS as a versatile material with high efficiency as a multifunctional sulfur fertilizer. PolyS pellets were prepared with added porosity to the structure, aiming to increase the surface area for biological oxidation. A study was conducted to understand the interaction of this system with the bacterium Acidithiobacillus thiooxidans, which obtains energy from S oxidation. Moreover, compared to commercial S8 pellets, oxidation in soil was significantly higher from the combined application of the porous PolyS with bacterium. PolyS was also investigated as a dispersant matrix for the controlled-release of other fertilizers, with the advantage of serving as a rich source of S for plants. Composites containing sustainable phosphorus (P) sources with different solubility profiles - phosphate rock and struvite - were synthesized to study the physical and chemical effects of PolyS as a matrix. A synergistic effect between PolyS oxidation and phosphate release was verified, with the local acidity of sulfate generation favoring phosphorus solubilization. The application of PolyS-struvite composites for soybean cultivation was then tested in a greenhouse, with a systematic study of fertilizer effects on root profile and plant development. Compared to conventional soluble sources, PolyS led to higher sulfur uptake efficiency, and the controlled release of P stimulated the production of fine soybean roots. Based on the results it could be concluded that the polysulfides offer versatility for the design of different fertilizer products, with added value as an efficient S source.

Much effort has been employed to improve the quality of embryos obtained by in vitro production (IVP) given the relevance of this technology to current livestock systems. In this context, dynamic IVP systems have been shown to be beneficial to the embryo once they mimic fluid flows and mechanical forces resulting from the movement of ciliated cells and muscle contraction in the reproductive tract. In the present study we sought to confirm these initial findings as well as assess potential molecular consequences to the embryo by applying microvibration (45 Hz for 5 seconds once per 60 minutes) during both oocyte maturation and embryo culture in cattle. As a result, micro-vibration led to cryotolerant blastocysts as indicated by the lower incidence of apoptosis following vitrification-thawing. Further analyses revealed epigenetic and transcriptional changes in blastocysts derived from the micro-vibration treatment, with a total of 502 differentially expressed genes. Enrichment analyses linked differentially expressed genes to “Oxidative phosphorylation”, “Cytokine-cytokine receptor interaction”, and “Signaling pathways regulating pluripotency of stem cells”. Yet, a metaanalysis indicated that the transcriptional change induced by micro-vibration was not toward that of in vivo-derived embryos. In conclusion, micro-vibration leads to bovine embryos of improved cryotolerance, but caution should be taken given the unclear consequences of epigenetic and transcriptional abnormalities induced by the treatment.

The present research was developed within the scope of the Graduate Program in Agroecology and Development at the Federal University of São Carlos - SP. Its objective was to characterize processes of water (In)justice suffered by rural communities in the Brazilian Semi-Arid region from the implementation of the Project for the Integration of Hydrographic Basins of the Northern Northeast (PISF). The research was developed in four stages, the first refers to a re-reading of quantitative data produced by the author of this research, for the development of his monograph, but which presents relevant information for the debate on Water (In)justice. The second stage consisted of a literature review on Water (In)justice. The debate was systematized and presented in the second section of this work. The third step is to carry out a field interview in the territories Vila Produtiva Rural Lafayette and Pau D'arco/Mulungu, located in the rural area of the municipality of Monteiro-PB. The field research consists of carrying out a qualitative interview to identify the possible water (In)justices present in the researched communities, considering the analytical dimensions that deal with accumulation, conflicts and actions of civil society, present in the theoretical framework. The fourth and last stage is presented in the systematization of field data. The processes related to ACCUMULATION were categorized into “Commitments of water sources”, “Concentration of water sources” and “Water commodification”; processes related to CONFLICTS were categorized into “Community Conflicts”, “Inter-Community Conflicts”, “Community vs State Conflicts” and finally “Community vs Ministry Conflicts”; processes related to civil society action were categorized into “Formations and partnerships”, “Struggles and social mobilizations” and “Projects” according to the discussions presented in section three of this work. The conclusions indicate that the water (In)justices are characterized in several fields, more in particular with regard to the conditions of access, quality, and commercialization of water, as well as in the conflicts generated by the PISF in a direct and indirect way. In order to combat injustices, the resistance of the victimized communities is attested through the actions of civil society, which has done a lot to repair the impacts caused by water injustices, which the territories were subordinated to.

Ciliates dominate microzooplankton and play an essential role in marine food webs. By ingesting flagellates, bacteria and other organisms from pico and nano-plankton, and then being consumed by zooplankton, ciliates are the main pathway of carbon flow that links the microbial loop to the classical trophic chain. However, the diversity and distribution of ciliates in the global ocean is still poorly understood due to the difficulty of observing and classifying these organisms under light microscopy. When fixed, most ciliates are lost or change their morphology, making their identification difficult. Thus, the use of molecular tools represents an opportunity to study the ciliate community in the ocean. Within ciliates, the Strombidiidae family is amongst the most abundant, but there are still few systematic studies at the global scale on the distribution, abundance and phylogeny of this important group in the ocean. This study aims to: 1) evaluate the phylogenetic diversity of Strombidiidae, 2) understand its distribution in the global ocean, 3) determine the ecological niche of the most abundant clades. We used a metabarcoding dataset (region V4 18S rRNA) of 1008 samples from the TARA Oceans and TARA Polar circum-navigation expeditions. We constructed a Strombidiidae reference tree with complete 18S rRNA gene sequences from the literature and inserted the metabarcoding sequences for phylogenetic assignment. Then we related the distribution data of these clades with environmental data to define ecological niches. The phylogeny of Strombidiidae revealed 20 distinct clades, almost all of them widely distributed in most oceanic regions. The most abundant clade (Strombidium_clade2) is cosmopolitan. Furthermore, we obtained 12 environmental clades whose sequences (V4 18S rRNA region) are not identical to those described in the reference tree, and thus, may represent new clades. Niche analysis showed that the different clades of the Strombidiidae family had different distribution patterns in the global ocean, determined by temperature, salinity and oxygen. The Arctic Ocean had greater abundance among the Strombidiidae clades and very characteristic niches were observed for these oceanographic regions. This work represents the first study of the taxonomic and phylogenetic diversity of the Strombidiidae family in the global ocean, thus contributing to the knowledge of the ecology of marine ciliates.

In the digitalization era several technology features have become essential in order to increase the productivity of industries and decrease the environmental impact during the product life cycle. This means that engineering, marketing, sales, and other areas that constitute a modern company are driven by data, which accumulates and tends to become more complex with time. Information acquisition and data storage technologies are at an advanced stage in the national industries. However, even though data from process areas such as engineering, manufacturing, processes, and services can be obtained, data integration, management, and implementation in the virtual world are not a focus of research. With the growing demand for individualized products, the digital twin offers an effective solution for modeling, development, and innovation. This work seeks to provide a better product-digital interface for better design execution and product development management, making the life cycle more efficient, integrated, and sustainable. Through the conducted study, a framework was developed for the initiation of engineering projects with the intention of building a digital twin and finally, this same project structure was put to test by means of a case study. The construction of the digital twin of an additive manufacturing platform, customized with a Delta-type robot, was started in the form of an integrated project from the requirements, generating at the end, a digital product, with all information integrated and related to the product objects and engineering project. Therefore, it is stated that the created process structure presents a valid and tested strategy for the initiation of any digital twin project, so that the product can follow the life cycle with all the necessary information for further manufacturing and service development.

Tuberculosis is the leading cause of death among infectious diseases, according to the World Health Organization, and represents a major public health problem. About 1.4 million people died from tuberculosis worldwide in 2019, with about 4,500 cases per year in Brazil since 2010. Early diagnosis of tuberculosis is essential for treatment to be more efficient, avoiding nonspecific therapies that contribute to the emergence of resistant forms of the pathogen. Current diagnostic methods, such as immunoassays and molecular tests, require infrastructure and specialized professionals, compromising diagnosis in low-resource settings. In this sense, new biomarkers have been researched for the development of new diagnostic tools. Among these biomarkers, we have the Hsp65 and CFP-10 proteins, which are found in different samples from tuberculosis patients and are secreted in the early stages of infection. Therefore, the present study presents the development of a paper-based immunosensor for the simultaneous detection of Hsp65 and CFP-10 proteins using a lateral flow system. For this, the biomarkers were immobilized on the nitrocellulose membrane for detection through the competitive model, in a device composed of the sample, detection, and absorption zone. Gold nanoparticles were functionalized with antibodies against the targets to act as detection labels. After optimizing the immunosensor in different experimental parameters, such as sample volume and incubation time, it was possible to build calibration curves for both biomarkers for the concentration range of 2.5 μmol.L-1 and 40 μmol.L-1 . The device presented several advantages over the diagnostic methods already used, such as low-cost, easy-to-use, fast results detectable with the naked eye, providing a promising tool for the diagnosis of tuberculosis at the point of care.

Chess is a game that stimulates the logical reasoning, spatial vision and critical thinking of practitioners. Several academic studies have already found the affinity between the practice of sport and the development of several skills. This paper deals with the use of the game of chess in the classroom as a tool to aid the competencies that mathematics seeks to develop in secondary school students according to the National Common Curricular Base (BNCC) for high school. For this purpose, research related to teaching was used through the playful to associate math exercises with chess exercises in order to find familiarity between the skills worked and the skills developed, thus producing a bibliographic/qualitative research. The work sought to show the existence of a positive correlation between the competencies established in the BNCC during practice and during the problems involved in the game.

Educational trends must adapt to the demands of society. In a world that increasingly requires creativity and problem-solving skills, it is necessary to train active and critical citizens. For this, one of the possible alternatives is to use Active Methodologies in the elaboration of lesson plans, in order to place the student as the protagonist of the teaching-learning process. This Course Conclusion Paper (CCP) investigates the concepts of Active Methodologies, Ethnomathematics and Interdisciplinarity, as well as the difference between "Exercise" and "Problem" in the mathematical context. Examples of active methodologies and suggestions for strategies to apply them in the classroom will be presented. The central objective of this CCP aims to bring greater meaning to the study of the concepts of regular polygons and their relationship with other areas of knowledge, in particular with Biological Sciences. To this end, it presents a mathematics lesson plan, focused on the Final Years of Elementary School, based on Ethnomathematics and one of the strategies of active methodology, Project-Based Learning or Problems. Among the results obtained, it is noteworthy that Active Methodologies, in addition to bringing results similar to those of a traditional class, also allow the development of self-confidence, self-esteem and student autonomy. More than that, the results showed that, by stimulating students' critical thinking in relation to the world they live in, the educator shows students that everyone has a role in society and that, with knowledge, a prepared and strong teaching team, the school community can mobilize large masses and make a difference.

Here we test whether the Serial Discontinuity Concept actually predicts the damming effect as a gradient break in the Continuous River Concept. Microcrustaceans (Cladocera and Copepoda) were collected at six sampling points along 815 km of the main channel in a large tropical river (Rio Parnaíba, Northeast Brazil) for 2 years. The composition, diversity, abundance and dissimilarity were studied, as well as the effects of environmental variables. The hypotheses tested were: i) the presence of a single reservoir disrupts the structure of microcrustaceans, with greater richness at points downstream of the reservoir due to the mixture of lentic and lotic organisms, as well as at points in the downstream stretch of the river, as expected in the Serial Discontinuity Concept, increasing zooplankton diversity and abundance; ii) there is loss of species in areas close to the municipalities as a result of the impact of effluents (lower values of beta diversity and nesting effect). A total of 48 taxa (Cladocera = 37 species, Copepoda = 11 species) and 18 new records were found for the river, reflecting the positive effects on a wide spatial and temporal effort. Both hypotheses were accepted, with the effect of a reservoir causing a break in the continuous longitudinal gradient and the dissimilarity increasing at sampling points close to municipalities. The environmental variables showed low variation between the sampled points, with the temporal variation in the Parnaíba river being more evident. The presence of a single reservoir influences the increase in zooplankton diversity and abundance, as there is an increase in taxa in the downstream lotic environment, in addition to the influence on the flow.

We have observed that the History of Mathematics often goes unnoticed by students during problem solving or the study of mathematical content. In this work we seek to analyze how is the approach of the History of Mathematics in some textbooks, from the 1950 to the present, focusing on its historical approach and the connection in the approach of mathematical exercises. In addition, we analyzed the teaching material from three schools, one state, one municipal and one from the private network, in order to identify the approach to the History of Mathematics in the exercises and in the theoretical part of the content. Then, we elaborate and apply an activity suggestion that relates the History of Mathematics with Egyptian numbers, allowing the student to visualize the history together with the resolution of problems and provide the student's role in the creation of mathematical problems involving Egypt
