In the last decades, the pharmaceutical industry has been going through an internationalization process of its operations. Due to the coronavirus disease (COVID-19), the planning of global pharmaceutical companies was directly affected in the search for an immunizing agent. In this context, the complexity of the supply chain increases, as economic and financial aspects influence the planning of the physical configuration of these networks. To date, the literature on optimization models for global supply chains, specifically for pharmaceutical production, does not incorporate financial feasibility issues in planning. In this way, this dissertation proposes to develop an optimization model for the global supply chain planning problem of a pharmaceutical industry incorporating financial indicators, mainly of investment viability. The model incorporates: (i) the net present value (NPV) in the objective function; (ii) the possibility of using equity or raising funds through loans and financing to open plants and distribution centers; (iii) the incorporation of compound interest in the calculation of financial expenses and; (iv) the alternative of investing the company's equity in the financial market. The problem addressed involves strategic decisions such as number, and location of secondary plants and distribution centers to meet the demand of the final markets, as well as the flow of products in the network. The model is tested with data based on two pharmaceutical companies with global operations that are producing vaccines for the Sars-CoV-2 virus. The results generated by the model were adequate, the following characteristics: the production of vaccines presented positive NPV, the financial analysis shows the high return on investments, and the opening of distribution centers (DCs) were outsourced. The contribution of this work is the incorporation of little-used financial aspects in global supply chain planning problems, allowing managers to make a better strategic decision based on the interconnection between operational management and corporate finance.

This theoretical research aimed to explain and analyze the conceptual bases of the Cultural-Historical Theory that allow to present a historical-dialectical materialistic explanation for what has been spread in the educational context as "learning difficulties", contrasting the hegemonic conceptions based on a biologizing and individualizing bias. This study was configured as theoretical, theoretically-methodologically based in the Cultural-Historical Theory which its premise understands the human being as a historical, social and cultural being and that the psychological constitution is established from the inseparability of the relationship of the individual with his social reality. The nature and sources of the research data were established as bibliographic, drawing on Vygotski’s “Obras Escogidas” as its primary textbook reference, focusing on Tomos III and V. The methodological procedures were based on the bibliographies recognition reading, pertinent information location to the research topic, bibliographies choices closer to the object of this study, carrying out critical readings, seeking information used for the conceptual deepening and realization of integrative synthesis presenting the investigation process product. The results showed that by undertaking a genetic analysis on the problem of so-called "learning difficulties", from its historical reconstruction, it is possible to highlight the causal dynamic links that are at the origin of this phenomenon and, finally, to understand it in its entirety. Among the conceptions that are at the essence of this phenomenon, we have the relationship established between the processes of teaching, learning and development that, in the hegemonic view, start from premises that, inadvertently, fall into biological determinism. The Cultural-Historical Theory, in turn, by offering a materialistic historical-dialectical interpretation for such processes, allows to reverse the logic of analysis by which the problem of “learning difficulties” is regarded. Concerning the results, we highlight four Cultural-Historical Theory fundamental propositions that allow us to build another theoretical interpretation to the phenomenon of “learning difficulties:” 1)The concept of a human being as a socio-historical being, 2) The social-nature of the development of the superior psychological functions, 3) The dialectic relationship between learning and development, 4) The method of the analysis of the phenomenon through the Cultural-Historical Theory. Thus, by offering another theoretical interpretation for this phenomenon, the Cultural-Historical Theory allows to demystify the view that blames students and their families for school difficulties and, consequently, collaborates to the proposition of more effective pedagogical practices to overcome this problem, we highlight that: 1) Teaching must be planned to encompass the students’ concept of proximal development zone to the content to be learned; 2) Assessment of learning and development are vital to the process of educational planning, 3) The Cultural-Historical Theory presumptions allow the teachers to change their perspectives about what would be perceived as “student limitations” into a transforming learning power. Finally, we consider that this study presented only an initial analysis on the possible relations between the Cultural-Historical Theory and the problems encountered during the schooling process, among them what the literature has identified under the terminology “learning difficulties”, and that more studies on this topic are necessary, from theoretical approaches committed to the educational institutions, education itself and society transformation.

Epoxy/glass fiber composites (GRE) were produced by filament winding with a view to application as a liner in a carbon steel tube to replace all-metal super duplex stainless steel column in offshore petroleum exploration. Changes in the Litestone 2210E commercial epoxy resin system containing methylnadic anhydride curing agent were carried out by adding 1,4-butanedioldiglycidyl ether (BDDE) as reactive diluent (RD) and excess of benzyltriethyl ammonium chloride (BTEAC) initiator, to improve the fiber wetting during processing and reduce the curing time, respectively. Viscosity measurements performed by plate and plate rotational rheometry showed that the viscosity of the epoxy system decreased with the addition of the RD. Dynamic curing kinetic studies using the Avrami model modified by Jeziorny and Ozawa were carried from differential scanning calorimetry (DSC) analysis. The glass transition temperatures (Tg) of the epoxy systems were measured by DSC and dynamic mechanical analysis (DMA). Increasing the initiator content anticipated the curing process and increased the curing enthalpy, but did not change the curing rate. The incorporation of DR favored the epoxy cure without significant changes in the curing enthalpy, and reduced Tg by approx. 38°C. Flat plates of unidirectional epoxy/glass fiber composites were produced by filament winding and subjected to tensile and flexural tests and scanning electron microscopy (SEM) analysis. The composites showed good wettability and interfacial adhesion and the addition of DR increased the strength and strain at break without significant change in the elastic modulus. The data indicated that the addition of DR is a viable way to optimize the filament winding processing as well as the curing step and thus optimize the mechanical properties of the epoxy/glass fiber composites.

This work succinctly presents historical and mathematical aspects of ancient and modern cryptography such as Caesar cipher, related ciphers, Vigenère cipher, Hill cipher and RSA cryptography. Guidance on the subject of cryptography and related activities in high school is sought at the BNCC and PCN-EM. The work develops mathematical requirements for an elementary understanding of the cryptographic systems studied. Among these requirements we have elementary concepts such as matrices, modular arithmetic and number theory, which are used in the presented cryptography theories. Some activities for the elementary school teacher to apply in their classes are suggested at the end.

The left and right medial prefrontal cortex (L & RmPFC) process emotional responses induced by stress-related stimuli, and LmPFC and RmPFC inhibition elicit anxiogenesis and anxiolysis, respectively. Here we sought to investigate (i) the mPFC functional laterality on defensive/anxiogenic-like behaviors in mice subjected to chronic social defeat stress (SDS); (ii) the effects of LmPFC inhibition (with local injection CoCl2) on the RmPFC glutamatergic neuronal activation pattern; and (iii) the effects of the RmPFC NMDA receptor blockade on the anxiety induced by LmPFC inhibition in mice exposed to the elevated plus-maze (EPM). Results showed that chronic SDS induced defensive-like behaviors followed by the rise of ΔFosB labeling and by ΔFosB + CaMKII double-labeling bilaterally in the cingulate (Cg1) and infralimbic (IL) subareas of the mPFC. Chronic SDS also increased ΔFosB and by ΔFosB + CaMKII labeling only on the right prelimbic (PrL). Also, left PrL inhibition increased cFos + CaMKII labeling in the contralateral PrL and IL. Moreover, anxiogenesis induced by the left PrL inhibition was blocked by NMDA receptor antagonist AP7 injected into the right PrL. These findings suggest the lateralized control of the glutamatergic neurotransmission in the modulation of emotional-like responses in mice subjected to chronic SDS.

Currently there are several studies that describe disability from the biological, legislative, social and historical-cultural perspective; however, there are few who give voice to people with disabilities, talking about these people is more frequent than talking to them. For this reason, this study aimed to investigate the understanding of acquired blindness and the changes that occurred in the lives of people with blindness in adulthood. The study also reflected on the changes that occurred in their lives after vision loss and analyze the strategies used to overcome the challenges of being a person with acquired blindness. For this, he used the Life History method that allowed giving voice to people to whom he seeks to understand, no longer analyzing his disease/deviation, but sharing of their lives. It is a qualitative approach and a descriptive research, which portrayed reality and phenomena, from the perspective of people with acquired blindness, knowing the characteristics of this population. The study included four people with blindness acquired in adulthood, aged between 40 and 75 years, who attend a philanthropic institution, located in a city in the interior of the state of São Paulo. For data collection, unstructured interviews were used, which were recorded in audio and fully transcribed, in which the participants freely told about their stories. The data obtained were analyzed from discourse analysis. The results indicated that in relation to the understanding of acquired blindness, for the participants, the concepts are distinct and formed at different times, most often based on popular conceptions, without denying the medical conceptualization of disability; but above all they understand it from their social relationships, which are often watered down by discrimination, stereotypes, stigmas and social isolation. We conclude that this study contributed to the understanding of blindness, from the perspective of people with acquired blindness, being beneficial to these groups that are silenced and stigmatized

In these study, nanoparticles with a core-shell structure of oxide zinc-carbon (ZnO@Carbon) were synthesized using the simple thermal decomposition method of Zn(CH3CO2)2•2H2O in a conventional electric furnace and a hybrid heat/microwave furnace. The ZnO@Carbon powders were characterized by structural, optical and photocatalytic techniques, aiming to analyze the structural order-disorder effects of their components. Initially, only samples synthesized by the conventional electric furnace were studied and it was observed that the order or disorder level of both the ZnO and the carbon shell dramatically affect the photoluminescent and photocatalytic properties of the ZnO@C composites. Furthermore, was clarify that the photocatalytic mechanisms of some particles of ZnO@Carbon is dependent of the type of light used (UV or visible). ZnO@Carbon particles were synthesized through a hybrid heat/microwave furnace and an electric furnace at the same temperatures. The microwaves generated changes in morphology, crystallinity and carbon proportion of particles. The hybrid furnace also reduce the minimal synthesis temperature for synthesis of ZnO@Carbon particles, thus obtaining a sample with 4 times the concentration of carbon obtained in a conventional electric oven. These sample allow understand better how changes in carbon materials affect the photoluminescent profiles and the photocatalytic activity of ZnO@Carbon particles, in addition to enabling a better adsorption capacity of ZnO@Carbon particles, generated by the greater composition of mass of carbon in the particles.

The active participation of students in activities that make sense to them is a very promising alternative to make Physics teaching more interesting and accessible. For that, students must be engaged in creative processes, through which they can act as young scientists communicating science. Another important factor in this process is the contextualization of subjects to be learned in the classroom with their daily lives, even though they have a more theoretical character, through theories and mathematical models, or a more observational character, through experiments or analysis of natural phenomena. Learning science through theater has the potential to bring together science and art inquiry. Students can learn science in a creative way while implementing a theatrical performance related to scientific concepts. In this work we use theater as a teaching methodology to introduce astronomy concepts in high school. We developed the script for a play called “Crazy System”, which was presented at a science fair at a private school in Mogi Guaçu city at São Paulo state. In the theatrical performance we explore concepts such as the geocentric and heliocentric systems, the movements of the Sun, Earth and Moon, days, nights, seasons, solar and lunar eclipses, tides, among others. The play was conducted by the teacher and the students themselves and presented to a general audience, quite diverse, in a playful and fun way. With this proposal it was possible to make the students understand the scientific concepts and the phenomena addressed, as well as to develop a spirit of cooperation and teamwork, allowing them to actively participate in the negotiation of the scientific concepts covered in the play, developing creative and thinking skills. Furthermore, as a dissemination activity, the students' theatrical performance contributed significantly to bring the school closer to society and to develop their own social and entrepreneurial skills.

The research objective analyzes the reconfiguration of watchrepair´s craft in the contemporaneity of São Paulo city, understanding to what extend the craft, with its notion of time, persists and resignifies itself. We consider that the watchrepair´s craft, despite suffering a sharp decline in modernity, reconfigures in the current context marked by digitalization of time. One of the hypotheses that we present for the reconfiguration of craft consists in the adaptation of watchrepairs to the transformations perfomed by the economic rationalization of the Third Industrial Revolution. A bibliographic survey was realized, considering the categories of craft, professions and time, which dialogue with the research problem. Furthermore, semistructured interviews were made with watchrepairs of São Paulo city, in order to understand how they reflect about your trajectory in the craft and what strategies they adopt to exercise it today. We observed that the decline of the craft that occurred during informational capitalism, generated others watchrepairs profiles and other work relationships in contemporaneity times. Apart from, we note that if the current flexible world is challeging the watchrepair occupation with their labor relations and digital technology, the watchrepair´s clients network and the collective and individual strategies in the virtual environment have been important for the reproduction of the craft in the contemporaneity.

The mechanism, the risk factors and the influence of sex on the incidence of frailty components are not completely known. In addition, the relationship between frailty and disability has been explored in a two-way street with studies showing that the frailty process increases the risk of disability and that disability increases the risk of frailty. However, there is a gap in the literature, as far as is known, no stratified analyzes by sex of the risk factors for the incidence trajectory of the number of frailty components as well as for the behavior of the functional disability trajectories in function changes in frailty status and their components over time. Therefore, in order to establish efficient rehabilitation programs for frail or in process of becoming frail older people, these knowledge gaps need to be filled. This thesis has two objectives: 1) To analyze sex differences in risk factors for the increase in the number of frailty components in 1,747 participants in the ELSA Study followed for twelve years; and 2) Analyze sex differences in the trajectories of the incidence of disability due to changes in frailty status and their components in 1,522 and 1,548 participants in the ELSA Study independent in ABVD and IADL and frailty at baseline also in a twelve-year follow-up. The main results found were that the increase in the number of frailty components, in both sexes, was associated with increasing age, low education, perception of poor vision, presence of depressive symptoms, joint disease, uncontrolled diabetes, C-reactive protein high and sedentary lifestyle (p <0.05). In men, the presence of osteoporosis, low weight, heart disease, living with one or more people and perception of poor hearing were associated with an increase in the number of components of frailty (p <0.05). In women, the increase in fibrinogen, controlled diabetes, stroke and the perception of regular vision were associated with an increase in the number of components of frailty (p <0.05). Obese women and men and overweight women showed a smaller increase in the number of components compared to the eutrophic. It was also found that women who became pre-frail and men and women who became frail had worse trajectories of incidence of disability (p < 0.05) than those who remained non-frail during the follow-up period. Slowness was the only component of frailty capable of discriminating the incidence of disability regarding BADL and IADL in both sexes (p < 0.05). In addition to slowness, weakness and low physical activity level (BNAF) also discriminated against the incidence of disability in men while exhaustion discriminated against women (p <0.05). However, we understand that although there are similarities in the factors associated with the trajectory of increasing the number of frailty components between the sexes, socioeconomic factors, low weight and musculoskeletal and cardiac alterations determined the frailty process in men while cardiovascular and neuroendocrine alterations determined the frailty process in women. Furthermore, slowness as a component and not frailty as a construct, seems to us to better signal the process of disability in the older people. Therefore, as its evaluation is easy, fast and accessible, screening for this frailty component should be prioritized in different clinical contexts so that rehabilitation strategies can be developed to avoid the onset of disability.

This study deals with the issue of school discipline and indiscipline from the teachers' narratives collected from effective teachers in public elementary schools in the city of Ribeirão Preto–SP. Therefore, we aim to investigate the normalizing process as a condition to produce school (in)discipline based on reports of experiences lived by teachers in their daily lives on issues involving the subject under analysis. The central perspective of the analysis is that discipline and indiscipline are the result of a production that takes place in the school institution, being inseparable from the elements, phenomena and relationships that produce them and that reverberate their effects on the way in which the subjectivities of those involved are constituted. in the schooling of children. These elements, phenomena and relationships were observed from the teachers' narratives collected in conjunction with the theoretical assumptions studied regarding the normalization process and disciplinary power. Among the various aspects discussed, we consider that not only students, but teachers, can produce and be produced under permanent surveillance, examination, standardization, control or correction directed at them according to the regime of truths established in their experiences. And, if on the one hand the narratives indicate that disciplinary practices are part of school demands, we emphasize that they are elements of a conflicting process in which, despite being constantly affirmed, the disciplinary power can also be denied, frustrated and threatened . The selected methodological bases are based on qualitative approaches, semi-structured recorded biographical interviews, bibliographic study and biographical research. The analysis of the collected data was carried out in the light of the biography of the experiences reported, that is, of a methodological approach that encompasses reflections on the subjects' acts and thoughts in a complex of relationships that permeate their experiences and the elements that make up their surroundings, inscribing them in the representations he makes about himself, the other and the group he belongs to. After the analyses, we found a disciplinary production based on the subject's normalization process consolidated and, in the direction of reflections on the production of discipline and school indiscipline and its effects, we believe that we think about them from the perspective of problematizing and denaturalizing this process, through the courage to tell the truth, could place them in a field of possibilities for criticism and reinvention.

The growing use of composite systems floors of steel and concrete in open spans design that aim to increase use flexibility of buildings using large open spaces, has stimulates the conception of composite systems floors in formats leave them more sensitive to vibratory effects and this way, meet human’s comfort criteria become increasingly important already in the early stages of structures design. The acceptance criteria of the national standards, based only control of fundamental frequency, lead to insufficient verifications, due the fact that real influence of vibrations induced by human’s activities in human comfort are related with peak accelerations. Within this context, this work present knowledge about dynamic behaviour of composite systems floors of steel and concrete for understanding of vibrations effects in the human comfort, together with of clustering of analytical procedures to calculate the fundamental frequency and acceleration of composite floors, procedures for numerical modelling, humans comfort criteria of vibrations induced by human’s activities, besides of, detailed examples using analytical procedures and application of human comfort criteria in composite floors design. Using analytical processes and numerical models for determine modal properties of 36 composite floors, after evaluating them based human comfort criteria of national standards and reputed international guides, was possible conclude that national standards need updated, as the results showed divers floors that not fit in criteria of reputed international guides design, when verified against in national standards, they would pass in the criteria of national codes.

Literature on naming emotional states indicates that people diagnosed with Autistic Spectrum Disorder (ASD) may have difficulty in developing such skills, and video procedures have been identified as effective for teaching this repertoire. The pandemic scenario of COVID-19 caused the suspension of in-person activities and, given the protective measures, such as social distancing, it was necessary to adopt a telehealth service (remote mode) for this research. The aim was to develop a parent-applied video program and investigate its effectiveness in teaching repertoires for naming emotional states from facial expressions to children with ASD. Three children with ASD, aged 3 to 6 years, and their parents participated in the study. The design used was a single subject A-B, and the procedure consisted of two experimental conditions: A) Baseline (probe) - control condition of variables, and B) Naming training - teaching condition. In Baseline (A) the summarized videos were applied (presentation only of the simulation situations in which the child-actress presented the emotions), and in the Naming Training (B) the full videos were applied (image presentation - frozen - with the face of the child-actress presenting the emotion at the beginning, with audio and the written word naming the emotional state, and followed by the simulation situation.The emotions trained were: 1) joy; 2) sadness and 3) fear. Data analysis assessed the relationship between children's responses to naming emotional states (dependent variable) in each naming training attempt applied by parents (independent variable). It was possible to develop the procedure, and the results showed that among the three participants, two learned (P1 and P3) to respond to the experimental task of naming the emotions of joy and sadness, and only P1 learned to name the emotion of fear. Keywords: Naming emotions; parente training; video; Autistic Spectrum Disorder.

Autistic Spectrum Disorder (ASD) refers to a neurodevelopmental disorder in which limitations to social effects are common, being relevant as processing focused on promoting social behavior in general, including the identification of emotions. With the global Sars-Cov pandemic, telehealth care based on Applied Behavior Analysis (ABA) has been shown to be an alternative, respecting the health protocols suggested to face such a moment. The present study aimed to: 1) evaluate and create conditions for teaching social behaviors for three children with ASD, from the IPO (Operationalized Portage Inventory), in adapted version and a natural situation, and 2) evaluate a teaching procedure using social stories for identification of four facial emotional expressions in subjects with ASD: joy, fear, anger and sadness. Three families with children with ASD were selected, who were assisted in a project with a broader objective in the area of telehealth in ABA. The dependent variables were: pre- and post-test of the child's performance in the IPO-adapted, number of correct responses in the socialization programs, number of correct responses in the emotion faces identification program, score in the interaction checklist and engagement of the intervention videos sent by mothers, score on EVALOF (Scaling Assessment of Oral Language in a Family Context) and measure of social validity of mothers. The independent variable involved the application of the teaching procedure directly by the mothers. The results showed evolution of children (P2 and P3) in skills in the five areas of development, in addition to the acquisition in identifying faces of emotional expressions. Although the three mothers engaged in the intervention, the form and period as it occurred varied among them. Qualitatively, improvements in the skills of mothers in the application of activities were analyzed and they were generally very satisfied with their participation and with the progress of their children. Thus, the proposal for telehealth based on ABA in the area of socialization has promoted the teaching conditions of mothers with their children with ASD in the home environment, during the pandemic period.

Given M a compact and connected surface without boundary, we define the braid groups of M, denoted by B_n(M), geometrically. We also explore its relation with the configuration space and the mapping class group of the same surface. In a more detailed manner, we present some relevant algebraic and geometric aspects of the braid groups of three specific surfaces, namely the closed disk, the sphere and the real projective plane. Later we consider p \colon \tilde{M} \rightarrow M a d-fold covering map and discuss the existence of an embedding from B_n(M)$ to $B_{dn}(\tilde{M}). In the possession of such result, we study the classification of the finite subgroups of B_n(\mathbb{R}P^2) and the mapping class group of the real projective plane. We conclude with the study of the algebraic realization of the finite dicyclic subgroups of B_n(\mathbb{R}P^2).

Historically Brazil has been solidifying as an important generator of technologies for the aircraft production (MONTINI et. al, 2019). The Brazilian aeronautical sector has dozens of small companies, aircraft manufacturers that strive to survive with few resources in a highly technological competitive environment. There are some difficulties to bridging the technological barriers and certification process to grow in the market. Faced with this context, the present research aims to develop a model of technological collaboration between small companies of the national aeronautical sector, based on a sectorial technological diagnosis. Was adopted the field research method where the investigation case is based on the way in which the small companies of the aeronautical sector could collaborate mutually in order to develop new technologies. The procedures were planned and subsequently executed in a pilot test. The research procedures are based on the construction of a theoretical conceptual structure, formed by a historical mapping, theoretical models of collaboration mapping, and mapping of diagnosis and strategic positioning. The data from a sample of several companies segmented as active in aircraft manufacture or assembly, manufacture of aeronautical components or parts and aircraft maintenance, were collected and analyzed using the five forces proposed by Porter (1989) and SWOT analysis as the main analytical frame (FAUSTINO, 2014). The results highlight: a) the historical scenario of the development of small companies in the Brazilian aeronautical segment in the last 35 years; b) the small aircraft market in which these companies are players; c) a diagnosis of the level of technological development of the small aeronautical industry in Brazil; d) an analysis of the segment carried out through the 5 Porter Forces and the SWOT matrix; and finally the proposal of a model to technological collaboration that enables the segment of small national aeronautical industries to reach higher levels of evolution and competitiveness. Thus, although there is an expressive interest in a model that can develop this segment of the industry, several other technical and political barriers were detected that need to be transposed. This research is expected to contribute to the development and survival of organizations operating in the sector, especially small companies and startups that lack specialized understanding to structure work and enable operations with lower efforts and costs. Also, a model of technological collaboration that allows companies to reach higher levels of competitiveness considering the government contribution only as sector regulator and inspector. The results contemplate a system of elements whose interactions are guided by Knowledge Management that contribute to the strengthening of the national industry. The main interested in this research would be the stakeholders of aeronautical sector's that want to overcome technological and certification barriers to achieve the best positions in the general aviation market.

When analyzing the Brazilian socioeconomic structure, it is observed that the real estate market is co-responsible for the improvement of the population's living conditions, as it contributes to the minimization of one of the main social problems, which is the housing deficit, which accompanies the history of the country to the present day. It is important to reiterate that the sustainability of real estate projects depends on prior knowledge concerning legal, economic, financial, technical, social, political and environmental factors. The recent Covid-19 pandemic has been responsible for several changes in different social spheres and, due to its effects, many challenges and reflections should guide the development of future real estate products during and after the pandemic. In this context, the main objective of this study is to propose a systematization for the viability of the real estate product, considering the main variables and issues related to the Covid-19 pandemic. To understand the variables related to the feasibility process of housing real estate projects and the impact of Covid-19 on product development, a systematic literature review and the development of a survey obtained through the application of questionnaires, aimed at professionals involved in the feasibility process of residential real estate projects. Based on theoretical reflections and on the respondents' perception, a systematization of the feasibility process for real estate projects was proposed in order to assist entrepreneurs in the quality and adherence of the final product to the customer's requirements, with a consequent reduction in business risks

Since the implementation of the vacancy reservation policy reaffirmed by the enactment of Law No. 12,711 of August 29, 2012 - known as the Quota Law - for self-identified black, brown, indigenous and public school students there has been an expansion of colectives composed by young black men and women inside Brazilian universities. According to the narratives constructed by them, the Black Student Collectives - CENs are political spaces for the (re)construction of identity, strengthening, affection, study and fighting for real practice of that Law. Given this context, in this study was read the processes of socialization, identification and construction of difference, based on the organization of CENs and the insertion of students in universities in the Southeast of Brazil whose stories and contexts can be considered distinct. To do so, I selected the universities UERJ (Rio de Janeiro/BR), UFES (Espírito Santo/BR), UFMG (Minas Gerais/BR), and UFSCar (São Paulo/BR) as places of observation, data collection and research production. My hypothesis is that the CENs appear displaced from other forms of black organizations and problematizing the idea of permanent identity of the group in question. The resulting tensions constitute a complex situation of cultural / racial identity. The methodology used gathers bibliographic research, historical-documentary survey, systematic and participant observations and interviews with members and former members. The research reveals a new political lexicon of Brazilian black youth.

This research seeks to bring together two distinct themes: studies on masculinities and ethnography carried out in virtual or online environments. Doing ethnographic research on the GROWLr bear-only app, I tried to think of other ways of doing anthropology that weren't stuck in old concepts like “field” and how this can be rethought and reworked within these new ethnographic practices. The concept of “digital ethnography” was created approximately 20 years ago by Christine Hine (2001), who also thought about the limitations that the traditional ethnographic method found nowadays when taken only within its arrangements created in the 19th and 20th centuries. With the exponential growth in the possibility of accessing the internet and the consequent increase in the relationships that take place in these environments, this field has become increasingly relevant and often indispensable within contemporary anthropology. Afterwards, I sought to reflect on the theme of masculinities from the point of view of gender studies and observed the bears in three dimensions, taking as a reference point the foucauldian concept of "practice of the self", which is part of the “hegemony-alethurgy-practice of the self” trio, as formulated by the philosopher in his last courses at the Collége de France. Finally, I was able to conclude that the virtual environment seems at the same time to facilitate and encourage more pronounced “masculine” behavior and also seems to make people more comfortable to say what they really think by “hiding” the immediate figure of the listener.

Considering the approaches to use of the CO2, this work aimed to study CO2 hydrogenation at gas phase and CO2 reduction (CO2RR) via electrocatalysis. Through these methodologies a wide variety of value-added products can be obtained, such as methanol and compounds with two or more carbon atoms (C2+). In a first stage of this work, Cu and Fe-based materials were investigated in the CO2 hydrogenation reaction. The production of methanol on Cu/Zn materials was influenced by the presence of promoters (Al, Cr, Ga, Nb, and Zr). The content, incorporation method to Cu/Zn, and chemical nature of the investigated promoters had a direct influence on the selectivity to CH3OH or CO. Cu50/Zn45/Nb5, prepared by co-precipitation, was the catalyst that showed the best activity and selectivity to methanol, because of its physical-chemical characteristics. Through spectroscopic investigations, intermediates of methanol synthesis were identified, and it was verified that CO adsorbs stably on Cu50/Zn45/Nb5, which contributes to the formation of methanol at the expense of CO. By applying Fe-Cu-Al-K to the CO2 hydrogenation reaction, CO, CH4 and C2+ hydrocarbons were obtained as products. The C-C coupling was favored when the material was reduced at 300 °C and exposed to higher reaction temperatures in range investigated here. In a second stage of this work, the combination of Cu50/Zn45/Nb5 and Fe-Cu-Al-K was evaluated by physical mixing and by overlapping beds of these materials. The formation of C2+ alcohols (C2+OH) was verified, attesting the complementation of the hydroxyl group formation (Cu50/Zn45/Nb5) and the carbon chain propagation (Fe-Cu-Al-K) functions. A statistical chemometrics optimization procedure was used to determine, among the investigated variables, the most favorable conditions for the C2+OH production. The model was experimentally validated and proved to be adequate. By DRIFTS, intermediates of the C2+OH formation on the 50%m Cu50/Zn45/Nb5 and 50%m Fe-Cu-Al-K physical mixture were identified. Finally, in the third and last stage of this work, the CO2RR was investigated on copper catalysts. Cu nanoparticles were more selective to the production of C2+ compounds, such as ethanol and ethylene, when compared to the smooth copper surface. Contrasting results of the CO2 hydrogenation and CO2RR on Cu and Cu/Zn-based materials, it was clear that the reaction environment has a significant influence on the products distribution.
