This present research of a typically historical bibliographic-documentary qualitative nature had as theoretical and methodological foundation the historical-dialectical materialist paradigm and was conducted by the following question: "What relationship between form and content is explained in online classes for children of the 1st year of elementary school who present the conceptual concepts of counting? The objective of this study is to analyze the relationship between the form and content of the conceptual index letters (numerical sense, one-on-one correspondence, sequence/ordering, grouping) presented in online classes for children in the 1st year of elementary school. The thesis defended was that the relationship between form and content of the conceptual links of the count directly implies the relationship between teaching and learning. For the construction of the information we attended and analyzed 37 online mathematics classes transmitted by CMSPi (35.92%) of out a total of 103, during the pandemic, for children enrolled in the initial grades, elementary school in the State network of São Paulo, in the period from 27/04/2020 to 29/10/2020, in order to understand how and what conceptual connection of counting are presented, identifying the relationship form and content of these issues. The results presented showed that counting cones were addressed in online classes: one-on-one correspondence, grouping/ordering and sequence, through challenges and use of manipulated concrete material such as tampons and toothpicks. Considering the definition of numerical sense this point was not addressed in any of the online classes analyzed. In relation to the contents addressed in the classes, there is the prevalence of numerical representation in the decimal base, which is immediately indicated, after the children make use of the correspondence one by one when they are faced with the control of quantitative movements. This form of control is called counting by teachers who organize and present online classes. In this sense, we found that online classes prioritized the form through the use of manipulateable concrete materials, such as tampons, chips and toothpicks, with emphasis on the perceptible elements of the concept that manifest themselves in the colors of objects and numerical representations. The concept of counting is restricted to the indication by children of the objects from the correspondence one by one with the little fingers and immediately, they must represent the quantities by the numerical symbols that are presented in the numerical basis ten. Number is synonymous with numeral. Content is synonymous with form. The idea of quantity becomes synonymous with the numeral that represents quantity. The zero digit is not treated. Children are not known that the zero digit is a placekeeper and that numerical base 10 is positional because it consists of regular groupings.

Au/ZrO2 and Au/In2O3/ZrO2 catalysts were developed for CO2 hydrogenation reaction and Au/ZrO2 for ethanol dehydrogenation. The monometallic gold catalysts supported on ZrO2 with different contents (0.3 to 5.0%w/w) were prepared by deposition-precipitation (DP) and analyzed by HRSTEM, DRIFTS-CO and in situ XPS as well as other characterization techniques. HRSTEM analysis proved the high dispersion of Au nanoparticles (NPs) with an average size around 15 Å. The ulltraestructural analysis also verified the presence of particles smaller than 20 Å (metal clusters) and isolated atoms with 2D and 3D configurations. The activity verified by ethanol dehydrogenation tests was higher for catalysts with Au content <1%. In situ XPS analyses indicated that a high dispersion of Au NPs, associated with heat treatment conditions at low temperature (200°C), promoted an increase in BE Au 4f7/2 binding energy, accompanied by surface defects and characterized by CO adsorption.The DFT results using clusters (3 and 13 Au atoms), indicated that the activation of ethanol on the surface of the clusters is not favorable, it must occur at the Au/ZrO2 interface and the determining step occurs on the surface of the clusters. The presence of low coordination sites formed by surface defects through the decrease of the Au charge and low heat treatment temperature suggest that they are of the 2D surface type, providing high catalytic activity and low activation energy (Ea) for the reaction. The increase of temperature in He treatment of the samples (from 200 to 600°C) increases the coordination number (NAu-Au) and the bond distance (RAu-Au), promoting a decrease of the catalytic activity. The adsorption of CO in linear form to the bridge type is favored with increasing Au loading and heat treatment temperature in He. This behavior is accompanied by the increase of NAu-Au and RAu-Au. Removal of defects on the surface by thermal activation leads to a decrease in electronic density and catalytic activity. Au/ZrO2, In2O3, In2O3/ZrO2, Au/In2O3, and Au/In2O3/ZrO2 catalysts were also evaluated for the CO2 hydrogenation reaction at high pressure (50bar). HRSTEM indicated a high dispersion of the Au on the support (In2O3/ZrO2) and of the In2O3 nanoparticles on the ZrO2. XPS spectra confirmed the interaction between In and Zr by deviations in the binding energy for the 3d 5/2 level of In and Zr and by differences between the reduction profiles by TPR-H2 for the bulk (In2O3) and the In2O3/ZrO2.Ex situ and in situ Raman, and XPS allowed confirming the increase in vacancies for this system with variation in the relative intensities of the decayed spectra. The yield to the methanol product was significantly higher for the Au/In2O3/ZrO2 system compared to the others (Au/ZrO2, In2O3, In2O3/ZrO2, and Au/In2O3), indicating that clusters and/or NPs of Au, as well as highly dispersed In2O3 NPs on ZrO2 favor the formation of oxygen vacancies in the active sites, increasing the CO2 adsorption strength, stabilization of reaction intermediates, and decreasing the reverse reaction of CO production with ~70% selectivity to methanol.

In the tangle of social relations, adolescence is processed and adolescents emerge. Adolescence is part of the individual and family life cycle, encompasses particular development processes towards identity assumptions and life projects, during which transformations are experienced at different levels. The COVID-19 pandemic imposed changes in social dynamics, among which is the tendency for adolescents to stay at home. This study proposed to explore the perception of parents about adolescence in the context of the pandemic. The proposed objective was to elucidate meanings and behaviors of parents in supporting adolescents in the COVID-19 pandemic. This is a qualitative study with a descriptive and exploratory approach, supported by Symbolic Interactionism and thematic Content Analysis. Semi-structured interviews were developed with mothers of adolescents between the 1st half of 2021 and the 2nd half of 2022, enabling and encouraging a space for speech to share perceptions and afflictions regarding the growth of children in a scenario of uncertainty. From the interviews, three categories were created: interaction with the adolescent in transformation; relations in the face of the pandemic and its consequences; adaptations, revelations and concerns arising from living together. This study provided a space for family discussion that enabled reflections on topics not always addressed in family life and that can have positive consequences for raising and living with adolescents. we believe that this research can contribute to deepening the available knowledge about families, adolescents and the pandemic, in order to support health professionals in the care and monitoring of families and adolescents, as it brings important discussions about family life during the process of social isolation and favors the construction of knowledge to support these individuals who, many times, are not assisted with quality due to lack of understanding and knowledge on the part of professionals.

Hyaluronic acid is a biopolymer with unique structural and rheological properties, that, initially, was produced by extraction from animal tissue, from rooster comb. However, it used non-ecofriendly solvents (chloroform) and high purification costs to remove contaminants from the rooster comb motivated its manufacture from Streptococcus zooepidemicus bacteria cultivation. Considering this, our study proposed to do a techno-economic-environmental analysis of microbial hyaluronic acid production incorporated to a bioethanol biorefinery with S. zooepidemicus. The techno-economic analysis was conducted in EMSO, while the environmental analysis was done via Life Cycle Analysis, with the approach of gate-to-gate. At first, sugarcane juice was evaluated as carbon source and the required steam and electricity were provided from the sugarcane factory, which resulted in a net present value (NPV) of US$ 18.43 million with a return-on-investment rate of 12.5%. Economic feasibility can enhance further by utilizing more fractions from the biorefinery, such as yeast surplus for yeast extract production and not adding the salts to the cultivation medium, which increase NPV in 37.1% and 11.6%, respectively. From the environmental point-of-view, the Life Cycle Analysis showed the step with more environmental impact was the Production, especially the sodium hydroxide consumption for the cleaning-in-place and pH control, representing 78% of the total impact for Global Warming Potential. As the cleaning-in-place cannot be suppressed due to rules of regulatory agencies, we assessed the effect of not controlling the cultivation pH and assess its impact by reducing sucrose conversion to 50%. Such change made the process economically unfeasible, confirming what the shaken flasks cultivation showed: pH control has a significant effect on the cultivation of S. zooepidemicus, especially in the growth aspect of it.

The present work has as its theme Freinet Pedagogy and academic research (theses and dissertations), between 1982 and 2018, which address theory and practice in the classroom. Célestin Freinet believed that techniques and practices would change according to the social, historical, political and cultural issues of a given time. Based on this premise and our personal experience with this Pedagogy, we chose our research theme and arrived at the following question: what transformations in the teaching and learning process can be perceived in Brazilian academic research between 1982 and 2018, based on the Freinet Pedagogy, who use techniques and practices in the classroom, in Elementary School I? From this, we set the following objectives: to know the academic research on Freinet produced in Brazil; discriminate which researches involve freinetian techniques and practices in Elementary School I; and to analyze the transformations that occurred in academic research in the teaching and learning process of Freinet techniques and practices in Elementary School I. For data collection, we used a bibliographical review as a methodology, based on the analysis of academic works, with a search in the Database Data from the CAPES Portal. We categorize and organize the research in tables and graphs, finally we have 9 works that were found in those that involve the teaching and learning process in the classroom, in elementary school I and that bring as a theme the pedagogical practices, techniques and freinetian principles . We find in the post-2000 works the connection with Marxist-based theories – Freire, Vygostsky, Pacheco, Wallon – different from those prior to that period that had their focus on Freinet. It appears that the essence of Freinet Pedagogy, its principles, remain until today, like a seed that germinates and bears fruit, spreading, sprouting in fertile soil.

Ecotoxicological tests realized to assess the environmental risks of pesticides to bees used by countries around the world are based on the protocols developed by the Organization for Economic and Cooperation, where is recommended the use of isolated active ingredients in surrogate species Apis mellifera Linnaeus, 1758 (Hymenoptera, Apidae). Once the representativeness of these protocols concerning the surrogate and pesticide mixtures is pointed out as gaps regarding the pesticide risk assessment, the development of ecotoxicological studies about stingless bees is a crucial step toward achieving a more protective regulatory process in Brazil. The present work evaluated the toxicity of a neonicotinoid commercial product, isolated and combined with an herbicide and a fungicide in three species of stingless bees considered possible surrogates for the assessment of environmental risk in pollinators in Brazil Tetragonisca angustula Latreille, 1811 (Hymenoptera, Apidae), Scaptotrigona postica Latreille, 1807 (Hymenoptera, Apidae) and Melipona scutellaris Laitrelle, 1811 (Hymenoptera, Apidae).Through adapted oral toxicity tests and comparison of the sensitivity of these bees with the current biological model, we highlight that existing protocols do not protect stingless bee biodiversity due to the greater sensitivity found in representatives and due to toxicological interactions when the insecticide was offered in binary combinations. Therefore, it is a major necessity to incorporate these pollinators into the Brazilian environmental risk assessment process and create regulations regarding the use of mixtures before or after pesticide application.

The introduction of non-native species is an event that can jeopardize the conservation of native species. The introduction of alien species is usually based on a few individuals and is linked to impacts related to the founder effect and the loss of genetic diversity, which is dependent on the initial effective population size, the population growth rate, and the characteristics of the new colonized environment, which may or may not provide adaptation to it. Invasive species can also favor hybridization with native species, when both species meet and manage to mate, which can be detrimental to biodiversity when one or both pure progenitor strains or species become extinct. The creation of contact zones between species that do not naturally co-occur can therefore pose a pressing threat to biological conservation. This is the case of a specific region of Serra da Tiririca State Park, located in the municipality of Niterói, Rio de Janeiro (RJ), where two pairs of the threatened species Leontopithecus chrysomelas (the golden headed lion tamarin, GHLT, endemic to the Atlantic Forest of Bahia) and a pair of Leontopithecus rosalia (the golden lion tamarin, GLT, endemic to the Atlantic Forest of Rio de Janeiro) were released in the 1990s. Due to the favourable conditions present in this area, these animals were able to adapt and reproduce successfully, generating a new population outside the natural range of L. chrysomelas. Over two decades, this population increased its density exponentially, and it was estimated that there were about 200 individuals, with phenotype of L. chrysomelas in that area in 2009, no individuals with the phenotype of L. rosalia were observed. In view of this event, and the fact that at that time there was only the suspicion of a possible illegal introduction of L. chrysomelas into the Niteroi region, an alternative measure to contain the growth and advance of this population to adjacent areas of natural occurrence of L. rosalia, was to carry out the translocation of individuals with phenotype similar of L. chrysomelas to a fragment of Atlantic Forest, located on the RPPN (Private Natural Heritage Reserve) Veracel Celulose in Belmonte, Bahia. In 2015, however, the illegal introduction of L. chrysomelas and also L. rosalia was confirmed. Although these individuals had the phenotype of L. chrysomelas, it is known that hybrids, besides having phenotypes intermediate to the inter-crossing species, can be more similar to only one of the parental species. Considering that both L. rosalia and L. chrysomelas are species classified by the IUCN as "endangered", investigating the existence of hybrids in this population and characterizing their genetic diversity and structure is relevant for appropriate management measures in regions where currently there are descendants of this population. In this context, the main objective of this study was to carry out genomic and genetic analyses to investigate the occurrence of hybridization and to characterize the genetic diversity and structure of this population. The data showed no signs of hybridization in the Niteroi population, confirming that the individuals are from the species L. chrysomelas. Additionally, genetic diversity values were comparable to those observed for other Leontopithecus populations, showing the absence of negative founder effect consequences and the excellent capacity of the species to re-establish its diversity in the Niteroi region. These findings are relevant to adequately manage individuals from the invasive population and for the conservation programs of both pure species.

Introduction: Patients with COVID-19 may have different impairments, especially in the most severe cases requiring hospitalization and intensive care. These impairments may be present even after hospital discharge, therefore, assessing exercise intolerance, the behavior of regulators and the level of physical activity of patients become fundamental. Among the forms of evaluation are the Six-Minute Step Test (6MST), Activities of Daily Living (ADL) and the use of wearable technology. Therefore, this dissertation resulted in two studies: Study 1 – Objectives: Verify and identify predictors of exercise intolerance assessed by the remote 6MST and compare performance, peripheral oxygen saturation (SpO2), and the feeling of dyspnea and fatigue in the test among patients who were hospitalized for up to 10 days with those who stayed more than 10 days due to COVID-19. Methods: This was a cross-sectional observational study, carried out by telemonitoring, of patients on average 30 days after hospital discharge due to COVID-19. The patients were evaluated by video call in two moments, the first moment was an initial evaluation for data recording and application of the inclusion criteria, and in the second moment the 6MST was performed. For monitoring during the test, patients received a 20-centimeter-high step in their homes, an automatic blood pressure device, a pulse oximeter and a modified Borg scale (0-10). Patients were divided into two groups: those who were hospitalized for up to 10 days (G≤10) and those who were hospitalized for more than 10 days (G>10). Results: Eighty patients were evaluated and it was verified that the length of hospitalization, cardiovascular and respiratory diseases, age and gender had a significant effect (adjusted R2=0.40) on the mean number of steps in the 6MST. In addition, 44 were hospitalized for up to 10 days (G≤10) and 36 for more than 10 days (G>10), and it was possible to verify that there was a significant difference between the groups regarding the need for intensive care (p<0.01), 6MST performance (p=0.04) and in the presence of oxygen desaturation (p<0.02). Conclusion: With the present study, it was possible to verify that the length of hospitalization, cardiovascular and respiratory diseases, age and gender had an influence on the exercise intolerance of patients after hospitalization for COVID-19 and that patients who were hospitalized for more than 10 days, showed greater exercise intolerance and desaturated more than patients who were hospitalized for up to 10 days, even 30 days after hospital discharge. Study 2 – Objectives: To characterize the responses of physiological variables during the simulation of an ADL circuit in relation to the physiological responses presented in the remote 6MST of patients after hospitalization for COVID-19 through wearable technology. In addition to verifying the association of physiological responses during ADL, exercise tolerance is verified by 6MST and physical activity level. Methods: This was a cross-sectional observational study carried out by telemonitoring patients after hospital discharge due to COVID-19. The patients underwent an initial assessment via video call and those eligible for the study received the material to perform the 6MST and the ADL circuit at their homes, including the smart T-shirt, made up of sensors that estimate the Frequency variables Respiratory (BR); Tidal volume (VT); Minute Ventilation (VE); Heart Rate (HR) and Cadence (CAD). For the evaluations, the patients were instructed to use the smart shirt for eight consecutive days for at least eight hours a day, and on the seventh day the 6MST was performed and on the eighth day an ADL circuit, both by video call. Results: Thirty-seven patients were evaluated and it was possible to verify significant differences between the ventilatory and cardiac variables during the execution of the 6MST with the ADL circuit and a moderate positive correlation between performance in the 6MST by the number of steps with CAD during the monitoring of the free ADL (R=0.594, p=0.000), correlation between performance in 6MST with the ventilatory variables in 6MST and in ADL1, however, there was no correlation between CAD in the monitoring of free ADL with the ventilatory and cardiac variables. There was also a moderate negative correlation between CAD and length of hospital stay (R= -0.590, p=0.000), and a weak negative correlation between CAD and the need for intensive care (R= -0.379, p=0.027) and 6MST performance with length of stay hospitalization (R= -0.374, p=0.023). Conclusion: The responses of the VE and HR variables during the ADL reached lower values when compared to the values reached in the 6MST. Both ventilatory and cardiac variables in 6MST were able to moderately predict the responses of the same variables in ADL, as well as the performance in 6MST was able to predict the level of physical activity, with longer hospitalization time and the need for intensive care negatively influencing the patients' exercise tolerance after 30 days of hospital discharge due to COVID-19.

Some social groups have been impacted by the COVID-19 pandemic, such as people with disabilities, people who experience situations of greater social vulnerability, indigenous people, children and teenagers. Studies have shown the damage that Covid-19 caused in the lives of children and teenagers with learning, social relationships, mental health and their development in general. Therefore, the objective of this study is to understand the implications caused on mental health of children by the Covid-19 pandemic with the perspective of teachers of an Early Childhood Education Unit. The specific objectives were: to identify the teachers' perception of children’s mental health and what are the strategies adopted by them, keeping in mind the mental health of these children during the pandemic. This is an exploratory, descriptive study with a qualitative approach. Teachers from an Early Childhood Education Unit participated. Data collection took place remotely, using a participant charatization form and a semi-structured interview. For data analysis, thematic analysis was used. The results showed an expanded understanding of mental health from the teachers’ perspective, involving aspects beyond the clinical picture and symptoms. In addition, it was identified that the pandemic impacted the development and mental health of children in general. The school appears as an important protective factor and promotion of children’s mental health and family support. It is hoped that this study can contribute not only to the understanding of a new and emerging reality, which is being reinvented day after day, but also to new reflections and discussions about intervention strategies and public policies aimed at children’s mental health.

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.
