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.

Fragmented knowledge has several impacts on the life of the learner because, in this way, knowledge is worked in such a way that concepts are isolated and distanced from the observer. One of the results of knowledge fragmentation is "Botanic Blindness", characterized by the difficulty to recognize the presence of plants in everyday life. Complexity challenges this simplifying view of knowledge by considering the world as a system. The main goal of this work was to know the participants' perception about Botany, and also to reflect about the possibility of inserting the Complexity perspective in the teaching of Botany in High School. To this end, we first searched for Botany concepts in the different Education guidelines directed to the teaching of Biology in High School, and then we prepared a dissertative questionnaire to know the perceptions of people who finished High School between 2015 and 2019, about Botany, which was answered by 50 participants. The answers indicated a difficulty in establishing correlations between Botany and other subjects, demonstrating a simple vision in the perception of the participants, and it was also noted an impact of specialization, directing the look of the participants to the theme from different perspectives.

Among the most widespread forms of practical application of ergonomic concepts, the activity centered ergonomic analysis stands out. This study aims to apply the Ergonomic Checkpoints Points (ECP) tool in activity centered ergonomic analysis, via Case Study method, to investigate possibilities of expanding the limits of collaborative solving of problems and the proposing of collective solutions, by using Expansive Learning concepts, from Cultural Historical Action Theory. This approach was applied in an environment characterized by access restrictions and lack of qualified personnel for doing more complex analyses, and in which the initial demand was focused on the design of artifacts in a small company of veterinary services. As results, we could point out the novelty represented by the joint application, in a case study, of concepts of Expansive Learning in situated ergonomic analysis, guided by ECP, resulting in aspects of learning and collective knowledge construction, bringing better situational awareness about ergonomic problems that affect the company, its operational context and the expansion of the consensual figuring of problems by company’s professionals, as immaterial aspects. As material results, we could cite data for establishing specifications, drawings and prototypes, instrumental for the development of solutions, through artifacts.

Modeling based on the Birnbaum-Saunders distribution has received considerable attention in recent years. In this work we consider the reparametrized Birnbaum-Saunders distribution with zero-adjusted (ZARBS) (SANTOS-NETO et al., 2012). This distribution admits the occurrence of zeros with positive probability, considering a discretecontinuous mixing model that is constructed using a probability mass at zero and a continuous component. ZARBS generalizes at least seven reparametrized Birnbaum- Saunders regression models. In this context, the main contribution of this dissertation is to study ZARBS under a Bayesian approach using the BAMLSS package developed in the R software, as well as to derive influence diagnoses for the model. Diagnostic methods have been important tools in regression analysis to detect anomalies, such as breaking assumptions in the stochastic part of the model, presence of outliers and influential observations. We assess the local influence on parameter estimates considering a perturbation scheme. To verify the potential of the proposed methodology, an application to a set of real data will be considered.

In the present work, we will use the Thermo-CalcTM software to model with the CALPHAD method the super-cooled liquid (SCL) that leads to the formation of metallic vitreous materials. This research aims to improve the database for thermodynamic calculations of SCLs in the computational study of materials, specifically some subsystems of the Fe-Mo-Cr-Nb-B system, since its application as a metallic glass coating combines exceptionally hardness, corrosion resistance and wear resistance. Thus, continuing the work of our group that modeled the Fe-Nb-B system with the same methods and models, we will describe the liquid molybdenum through the 2-state phenomenological model as well as the binary liquids Mo-Nb and Mo-B.

In the Brazilian context, the percentage of black and mixed-race women who play the role of mothers is higher than that of white women. Although very rare in the field of Occupational Therapy, studies show that the black population, specifically black women, experience inequalities and face situations of racism on a daily basis. In childrearing, the conditions of racial violence remain, expressing themselves in symbolic and physical violence in school contexts, work environments and in State policies. This study seeks to answer the following question “How does the experience of racism faced by black women affect their maternal occupations?”. The research, with a qualitative approach, adopted the body mapping storytelling that is based on oral narratives, graphic and artistic resources. Ten female mothers with a mean age of 35.9 years participated in the study. The generated data were analyzed through thematic analysis. The results are presented in three parts: Part I. Ten motherhood stories narrated through body maps storytelling; Part II. What is a collective problem? Impacts of racism in the daily lives of black women mothers; Part III. Proposed agenda: exposing the messages of black women mothers to others. The centrality of the elements of race and racism is highlighted in the participants' narratives, which allow the identification of the processes of constitution of black identity permeated by episodes of violence in different contexts, with the school as the main stage. It is noted that, in the mothering process, from before conception to parenting and education, black women deal with concerns and fears related to the idealization of this child, as well as feelings of self-vigilance in spaces of racial socialization. When raising children, they even go through repertoires of racial rituals and etiquette that continue to be linked to a racist structure, albeit in an unintentional way. The study shows that black women mothers develop an occupational imaginary constituted and based on the maintenance, rupture or support of the transgressive teachings of the mother figure, as well as the individual elaborations of the constitution of their own black racial identity and consciousness, which may be related to a subjective level, and not necessarily at a political level. The occupational imaginary of black mothers materializes through an ingenious care work that seeks the protection and personal fulfillment of their children, but does not necessarily prepare and protect their children for the strengthening of black identity and mitigation of the complex and violent effects of racism. From a technical-professional point of view, the study provided foundations on the singularities and particularities of black mothers and childhoods that demonstrate the urgency of considering the specificities of these lives in the field of occupational therapy. This will guarantee the commitment and the ethical-political horizon in the construction of professional practices and innovative public policies capable of transforming the occupational contexts in which institutional racism is produced and perpetuated.

This thesis investigated how intra-party democracy has unfolded within two of the largest Brazilian political parties: PT and PSDB. For such, based on a case study, we aimed at the identification to the potential synergies and/or tensions between intra-party democracy and the process of party institutionalization, the formal party organizational structures and the process of candidate selection in PT and PSDB parties. The case study was carried out based on quantitative data, bibliographical sources, documents and semistructured interviews with leaders and candidates that ran for the Chamber of Deputies by the state of São Paulo in the 2018 election. As a result, we identified the existence of contradictory trends related to the implementation of internal democracy within the political parties in question, which at times move towards an expansion of grassroots participation, while at other times advance towards the autonomy of the leaders in detriment to the grassroots party members.

The worldwide outbreak of the coronavirus pandemic (COVID-19) and other emerging microbial infections have attracted particular interest in the design and development of new biocidal agents with a broad spectrum of activity. Since then, efficient strategies need to be implemented for the rapid diagnosis, prevention, control and treatment of the SARS-CoV-2 virus, its variants, and other opportunistic pathogens. In the current scenario of SARS-CoV-2 infections, the technological challenge lies in the development of economically viable biocidal systems, reusable and capable of inactivating opportunistic pathogens, thus reducing the risk of infection and transmission. In this sense, Ag-based materials used in small quantities can become attractive for the development of new biocidal technologies. α-Ag2WO4, which already shows biocidal activity, when modified by electrons or femtosecond laser increases its biocidal activity up to 32x, against resistant bacteria (methicillin-resistant Staphylococcus aureus) and fungi (Candida albicans) due to the generated metal-semiconductor interface (Ag/α-Ag2WO4). In addition, this modification makes this interface selective for combating bladder cancer cells (MB49), versus healthy cells (BALB/3T3), using model mouse cells. Ag/SiO2 immobilized on ethylene vinyl acetate (EVA) was another studied interface which showed 99.99% inhibition of bacteria (Staphylococcus aureus and Escherichia coli) and fungi (Candida albicans), besides eliminating in just 2 minutes over 99% of SARS-CoV-2 virus replicates. In this way, safe biocidal technologies can be obtained using silver-based metal-semiconductor interfaces, which can be applied to the design of personal protective equipment (PPE), packaging, fabrics, hygienic implements such as implants and prostheses, and other devices economically feasible to combat the increase in pandemics and fatal risks associated with various pathogens.

This thesis analyzes the insertion of women as subjects of humor, more specifically of stand-up comedy, whose professional trajectories and performative constructions are marked by difference and the place of inequality they occupy. Based on a qualitative methodology grounded in interviews with 25 research interlocutors, on the analysis of internet videos and bibliographical research, I support the ambivalences in the debates about women as producers of humor, thinking about the key to the exercise of power. I argue that these ambivalences indicate shifts towards those that were not previously considered as producers of humor, while there are permanencies. Through performance studies, studies on laughter and humor, gender studies and studies on women and humor, I seek the comic making of the stand-up comedy and its power effects on the research interlocutors. I analyze the dispute for professional spaces between the circuits of comedians and the performative strategies of the research interlocutors, seeking how these women organize themselves, establishing ties and networks, to produce and create their own scenes and how this movement also reflects a greater diversification of the stand-up consumer audience. I explore the themes of women's narratives in stand-up comedy and argue for how they are motivated by their “annoyances”. Finally, I argued that, with the success of the performance, there is an exercise of power and transit of status by the comedians, who find in stand-up comedy a comedy model that allows them to control the comic narrative of that time and stage space without taking on other characters.

The need to strengthen concrete beams to increase the load capacity due to change not foreseen in the initial project or to problems related to the degradation of this structural system makes the use of composites in Fiber Reinforced Polymer (FRP) a viable alternative for the execution of strengthening systems. However, due to the environment in which FRPs are inserted, their durability can also be affected over time. In this context, the present research aims to evaluate the degradation in the accelerated condition of reinforced concrete beams with and without using the strengthening system with carbon fiber sheets when immersed in constant humidity and controlled temperature. For this, eight reinforced concrete beams were made, with dimensions 12cm x 20cm x 250cm, longitudinal reinforcement rate equal to 0.75%, and concrete with compressive strength of 30MPa. The set of eight beams were divided into two groups according to the exposure environment; four were kept in natural environmental conditions, and four were exposed to the accelerated degradation protocol. In addition, each group had two pairs of beams with and without the application of CFRP strengthening. As a result, there was a significant increase in the load capacity for beams strengthened with CFRP compared to not strengthened, with an average increase of 41.5%. Regarding the influence of the environments, after the exposure period, the beams without the CFRP strengthening system showed similarity both in behavior and in the mode of ruin. However, the strengthened beams showed changes in the failure mode, changing the ductility of the models. To analyze the average bonding stress between the concrete and the strengthening system, pullout tests were executed, showing a reduction of 35.7% compared to the reference model. Finally, the analyzes were performed based on normative recommendations, comparing their maximum load and strain results with those obtained in experimental tests. Therefore, according to the ductility analysis, material deformation, cracking, and failure mode, there was evidence that the humid environment with controlled temperature may have caused degradation in the connection between the strengthening system and the concrete substrate.
