The Torcida Jovem (Young Fan Club in English) of Botafogo-PB is the largest and oldest organized fan group of Botafogo Futebol Clube, the main club in João Pessoa. For two uninterrupted years, this research engaged in an ethnographic immersion with the Torcida Jovem, involving long-term participant observation that experienced many of the fans' collective experiences and interactions. The festivities, the pista (clash between soccer fan clubs in free translation), the dance, the fan performance, the caravan, the attack, the ambush, the dialogue with the neighborhoods, the ideology, the procedure, the daily encounters, the relationship with the impoverished city periphery, the march, the activity, and the procession. Above all, negotiations, segmentations, fissures, pacifications, and antagonisms that produce an intricate network of alliances and rivalries among organized fan groups throughout Brazil. Furthermore, the study reflects on violence, codes of conduct, and rules defining "being a fan" without forgetting the always tense relationship between organized fan groups and state security forces. This thesis delves into all these aspects.

Grynfelt's hernia is a rare pathology that presents as a defect in the posterolateral abdominal wall in the upper lumbar triangle. Both its diagnosis and treatment are requested due to its infrequent occurrence and anatomical complexity. What is presented is a bibliographical research of articles published between the years 2019 and 2023 focusing on surgical techniques for Grynfeltt hernia without associated complications. The search was carried out in the “PubMed” database, using the descriptor “Grynfeltt hernia”. There was no restriction due to the study methodology. Initially, 19 studies were identified, of which 11 were excluded if they did not meet the pre-established criteria (surgical management of hernias of the upper lumbar triangle without other associated pathologies). Only articles in English were selected, totaling 8 studies selected to be recorded and detailed. Among the articles, 6 case reports, 1 systematic review and 1 didactic surgical description were selected. It is concluded that Grynfelt's lumbar hernias are rare pathologies, mostly unilateral and asymptomatic, requiring high clinical suspicion for their diagnosis. Complementation with imaging examination favors surgical planning, in which different techniques (open versus laparoscopic; with mesh versus without mesh) can be used with favorable outcomes for patients.

This final paper aims to expand the reflections developed during the Scientific Initiation projects, carried out between August 2020 and October 2022. Both researches funded by CNPq, and entitled: “Literatura digital brasileira: a perspectiva dos criadores” and “Literatura digital nas redes sociais: um estudo sobre a perspectiva de quem produz”, we aim to critically document, through interviews with the authors, the characteristics of Brazilian digital literature. Based on the interviews, a reflection was carried out regarding the results (responses) obtained. Thus, we define the construction of present work, in order to understand and develop the point of view of two authors in front of their products, and mainly at this authorial level. To carry out this study, we rely on the ideas discussed by literary critic Antonio Candido, researcher at the Federal University of São Carlos, Luciana Salazar Salgado. We also delve into the Theory of Polissystems developed by sociologist and linguist, Itamar Even-Zohar, as an intuitive way of understanding the way the authors define digital literature.

During the COVID-19 pandemic, concerns arose about the risk of generating aerosols and transmitting SARS-CoV-2 to healthcare professionals during airway management procedures. These are primary interventions in the care of critically ill patients, with no possibility of suspension or postponement. In this context, several technologies have been proposed to reduce the risk of transmission of respiratory infections in hospital and out-of-hospital health services. Objectives: To evaluate the effectiveness and adverse effects of new technologies and procedures for obtaining an advanced airway in preventing the transmission of respiratory infections to healthcare professionals and patients. Materials and methods: This systematic review compared new technologies and procedures with traditional techniques in situations in which adult patients (≥18 years) underwent procedures to obtain an advanced airway, covering searches in the Medline, Embase and Web of Science databases in English, Portuguese and Spanish. The selected studies were assessed for risk of bias using the ROBINS-I, ROBINS-E and RoB 2 tools. Results: 1279 non-duplicate articles were identified, 57% of the studies being produced during the pandemic period. Three studies were selected for the systematic review, two cohort studies and one open randomized clinical trial. Many studies were excluded because they used new techniques that were not tested on real patients or without a comparative control group. There was no evidence that modifications to advanced airway procurement protocols altered the risk of SARS-CoV-2 transmission, nor that they were associated with a greater occurrence of adverse events. However, the selected articles were classified as having a high risk of bias. There was also a technical challenge in directly measuring the reduction in the risk of healthcare professionals contracting respiratory infections during procedures, both due to difficulty in documenting proven infection and because it was not possible to exclude other sources of infection. Discussion: There was great scientific production in the period, but with methodological limitations in the studies identified. The pandemic was a factor that stimulated scientific production, but limited the quality of evidence. The abundance of studies proposing new techniques was not accompanied by comparative effectiveness studies in terms of reducing SARS-CoV-2 transmission, making it impossible to assess their clinical usefulness. Conclusion: The pandemic stimulated the development of new techniques and procedures to ensure safety in obtaining an advanced airway. However, these methodologies still need to be evaluated regarding their effectiveness and safety, in addition to the costs of their incorporation into clinical practice.

What functions are attributed to parliamentary oppositions in representative democracies and how do they perform such functions in the Brazilian context, in the Chamber of Deputies? These are the main questions that guide this research. The internal regulations determine that for the composition of the members who will take on the Permanent Committees role, the criterion of party proportionality must be taken into account, thus, there is a recurrent practice in the composition of the Labor and Public Service Commission (CTASP) of the exchange of seats on committees. The acts of the Board of Directors of the Chamber of Deputies were used, and the mirrors of the composition of the committees, which explain who the official vacancy would belong to and the party that in practice occupied the vacancy. The methodo-logy used is a case study, based on a descriptive analysis. In turn, the results have shown that the tendency to exchange seats continued to be present, sometimes in favor of the coali-tion, sometimes in favor of the opposition

The increase in energetic consume are the cause of great concern effects, therefore, sustainable measures are sought in all sector. The building sector is the third largest consumer of energy, hitting over 50% of the electricity and over 30% of all the energy consumed in Brazil. To encourage the application of energy efficiency measures on buildings, certifications were created, such as the National Energy Conservation Label (ENCE, in its Portuguese acronym), that evaluate the usage and impact of such measures in a building. The ENCE classifies an edifice in categories, from A, to E, with different classification methods to residential buildings and to commercial, service and public buildings. The obtention of the level A National Energy Conservation Label is mandatory to new federal public edifices. This assignment targets the study of an existing public building to identify its classification, following the methods proposed by Technical Requisites of the Quality of the Energy Efficiency Level for Commercial, Service and Public Buildings (RTQ-C in its Portuguese acronym) and by the new Inmetro Normative Instruction for the Energy Efficiency Classification of Commercial, Services and Public Buildings (INI-C). Therefore, the building that houses the Rectory and Central Administration of the Federal University of São Carlos (UFSCar) was selected. This assignment made use of project documents and specific data collect on site or used from previous studies carried out in the edifice. Bibliographic database was used to provide data of equipment and the necessary correlation. The RTQ-C’s prescriptive method was used on the building, seeking to obtain a provisional classification of its energy efficiency, and INI-C’s simplified method, resulting in a definitive classification. On RTQ-C’s analysis, the building achieved level B of energy efficiency. However, on the INI-C analysis, it was verified that it’s not possible to apply the simplified method for hybrid edifices with the geometric characteristics of the analyzed building. Therefore, there was no consideration of natural ventilation, only artificially conditioned rooms. On the general classification, efficiency level A was obtained, resulting in an improvement on the classification comparing to RTQ-C’s method, with an evolution on the envelope. This result implies that the building complies with what is required by current legislation. Concluding, measures that will possibly improve the building energy efficiency are presented. This study concludes, based on bibliographic review and the realized applications, that the replacement of RTQ-C by INI-C was adequate.

Despite growing recognition of the Cerrado importance, our understanding of how to conserve and restore non-forest ecosystems in the tropics remains limited. In this study we aimed to evaluate, over three consecutive years the potential of different techniques for cerrado sensu stricto ecological restoration in relation to legislation for ecological restoration projects evaluation as reference standard and their influence on the structure and composition of soil seed bank and on soil physical and chemical attributes in an abandoned pasture area invaded by invasive exotic grasses with low natural regeneration of native species. Our results indicate that seedling planting using herbaceous, shrub, tree and liana species were only able to meet legal reference standards for soil coverage by native vegetation, presenting an approximate cost to that of forest restoration projects, highlighting its potential for large scale implementation. The limited and directed supply of nutrients to the planted seedlings did not generate changes in soil physical and chemical evaluated attributes. Despite the decrease in soil permeability resulting from experiment implementation and operations carried out, the restoration techniques obtained higher hydraulic conductivity results than control plots, indicating that cerrado sensu stricto restoration generates positive impacts on soil permeability. The differentiation with other evaluated treatments regarding emerged seedling density and diversity from soil seed bank shows that seedling planting was capable of generating positive impacts on the potential for natural regeneration of degraded cerrado sensu stricto ecosystems with low resilience. Our study indicates that seedling planting can provide superior results in a shorter time for cerrado sensu stricto restoration compared to assisted natural regeneration or abandonment (passive restoration).

After the extended periods of drought that occurred in 2014-2015 in the state of São Paulo, the greater Metropolitan Region of São Paulo, felt what in fact is a water crisis scenario, discussions regarding water availability in Brazil and its heterogeneity of distribution between the Brazilian states and the basin management quality has been growing and gaining attention from the entire population. With the population growth and the accelerated expansion of urban centers, often unplanned, providing drinking water with proper availability, quality and pressure to the entire Brazilian population becomes a difficult task in this context. In view of the above, this work addresses the topic of water losses in supply systems with focus on the distribution networks, gathering information on the definitions of real and apparent losses, its main causes, economic and environmental impacts, and some of the main combat strategies against the losses. The goal is to carry out a bibliographical review regarding the state of the art on the topic of water losses and demonstrate the multidisciplinary nature of relevant topics necessary to understand and combat the phenomenon of losses in distribution networks. The collection of searched data and academic papers demonstrate that at a national level, Brazil has high loss rates and several studies show that the reduction of losses can make significant contributions to the supply capacity of the distribution networks and can reduce the economic and enviromental losses related to water for the the entire society.

The universalization of basic sanitation in Brazil still faces challenges in all its dimensions - water supply, sewage disposal, drainage and rainwater management and solid waste management - especially in the peripheral areas of large urban centers. The accelerated and disorderly growth of cities has intensified the construction of precarious settlements around urban centers, since public actions and services have been more concentrated in these places. Despite the visible importance of these services for public health, a history of public policies, laws and the definition of a legal framework to achieve maximum service in these regions, the universalization of sanitation is still a challenge due to the lack of accessibility to services. The PAC (Growth Acceleration Program) in 2007 was a program of great importance for the basic sanitation sector, since more financial and structural investment was directed towards the country, but it was not enough. The aim of this study was therefore to gather data on the sanitation situation in Brazilian slums, in order to identify the current situation and the difficulties faced in universalizing these environmental services in outlying areas. The lack of planning in city management and the constant increase in irregular housing have resulted in improvised solutions, greater real estate irregularity and the inaccessibility of companies and consortia to provide sanitation services. The complexity of the challenge of providing basic sanitation in the country is aggravated by the unequal distribution of these services, predominantly affecting slum dwellers, the illiterate, the poor and other vulnerable social groups. The access deficit in these groups highlights the need for more inclusive and universal public policies. The progress made in terms of sanitation in the communities is notable in the region that already has greater access to services, showing that the other regions of the country still need attention from the public authorities.

Chemistry teaching in the final years of elementary school is done within the science discipline. In the ninth year, according to the BNCC, students should learn about atomic models, emphasizing the evolution process of these models over time. One topic usually addressed within this ability is electronic distribution through the Linus Pauling diagram. In this context, the objective of this work was to develop a didactic sequence in order to present Schroedinger's atomic model and, through this, explain the origin of the Linus Pauling diagram for ninth year students from a private school in Sorocaba. The didactic sequence included some themes of quantum mechanics, and featured: a previous activity, an expository class, the elaboration of an electronic distribution model and a final activity. The analysis of the responses to the activities showed that there was advancement in the understanding of the concepts of quantum mechanics by students, even at the introductory level. The atomic representations designed by them after the sequence corroborate the perception of advancement in the understanding of the atomic structure. In addition, the concrete model helped students better understand the new concepts, both during their development and their use to exercise electronic distribution. The application of the sequence allowed to conclude that students in the final years are able to learn concepts of modern physics and that the conceptual discussion in this type of content is very enriching for the maturation of the teaching-learning process. Through these discussions, the exchange between peers and development of the concrete model, students have the possibility of achieving meaningful learning, connecting new concepts to the old and advancing beyond mechanism associated with memorization processes.

The top tier soccer coaches of the male brazilian teams have a plethora of specific knowledge to act in thein field, such knowledge was acquired through study and practical experiences. Those studies are the focus of this monograph, conducting a review of previous information and, then, analyze the formation of the coaches that worked in the clubs of the A Series in the Brazilian Male Soccer Championship 2023. Therefore, the research objective consists in interpret and analyze the formative process of the soccer coaches that worked in said championship. We used qualitative methodological bases, conducting documental and bibliographical research, respecting the obtained information using the documental technique to expose collected data in the most evident way. Then we conducted the analysis, categorizing and adding the obtained results with the courses from the considered institutions, looking for the general characterístics surrounding the coach profession in Brazil. The CONMEBOL and UEFA confederations have established minimal requirements to federations and institutions within each country, qualifying their soccer coaches in different levels. These courses aim to elevate the technical and tactical patterns of playing, and even with the standardization of courses there are differences in cultural formation regarding styles and approaches from coaches. That is due to the way they played and learned throughout their lives, making them unique and different in the plethora of technical and tactical knowledge passed on the elite brazilian soccer players, creating a diversity of technical and tactical applications that are seen within the field.

Public higher education institutions in Brazil are legally obligated to develop Solid Waste Management Plans (PGRS), emphasizing environmental responsibility and sustainable waste management. Thus, this study was conducted through documentary analysis of the PGRS at the Federal University of Santa Maria (UFSM) and the Federal University of Pernambuco (UFPE), following the guidelines of the National Solid Waste Plan (PNRS) and other applicable regulations. Both institutions were selected, and the analysis was carried out based on items established in a checklist, in addition to using the SWOT matrix. The analysis of both plans revealed gaps, particularly concerning environmental liabilities, shared responsibility actions, and the scope of waste types on campuses. It was observed that few Brazilian public universities have an identifiable online PGRS. In this context, collaboration between universities and government bodies becomes crucial to align policies with the institutions' needs and capacities, promoting an integrated and sustainable approach to solid waste management. For future research, it is suggested to analyze the implementation of PGRS in international universities and different types of educational institutions, seeking a better understanding of their effectiveness in waste management and handling.

Waterproofing is one of the most crucial stages in civil construction. Recent studies have reported significant improvements in the waterproofing behavior of mortars containing bentonite. However, the addition of high percentages of this additive can result in a reduction in the consistency and fluidity of mortars, affecting the hydration process of Portland cement and the final properties of the products. In this context, this dissertation aimed to evaluate the use of activated sodium or calcic bentonite as a low-cost waterproofing additive in the preparation of optimized polymeric mortars. For this purpose, the preparation of a commercial mortar and others formulated (based on ratios of 3.5:1 and 3:1 – ratio of solid:liquid components) containing varied amounts (0-6 wt.%) of activated sodium and calcic bentonite was carried out. The chosen bentonites were characterized, and the performance of the mortars was evaluated through tests of fluidity, water absorption, mechanical resistance, watertightness tests, and microstructural analysis. The results indicated differences in the chemical composition of the bentonites, with activated sodium having smaller particle size, higher reactivity, and, consequently, three times greater swelling (25 ml/2g) than calcic bentonite (8 ml/2g). In general, all analyzed mortars showed reduced flow with the addition of bentonites. Furthermore, a significant reduction (6.17%) in water absorption was observed in samples containing 6wt.% of activated sodium bentonite compared to the reference mortar. Watertightness tests confirmed the applicability of mortars prepared with 2wt.% of calcic or sodium bentonite. The incorporation of up to 2wt.% of activated sodium bentonite into the commercial formulation resulted in an 18.6% reduction in water penetration after 48 hours under positive pressure of 0.25 MPa.

In the scenario of climate transformations, water resources play a vital role, emphasizing the urgent need to preserve, manage, and adapt humanity's water sources to ensure sustainability and well-being for future generations. Within this context, hydrological modeling is essential to understand flow patterns and risks associated with extreme events such as floods. Accordingly, this study focuses on hydrological modeling in the Embu Mirim River Basin, located in the state of São Paulo (UGRHI-06), with a focus on predicting critical precipitation intensities and, consequently, peak flows. Using the I-PAI-WU method, an enhancement of the rational method for basins between 2 and 200 km², the research aims to analyze and predict maximum water flows in the region. The methodological process included basin delineation using geoprocessing tools, adopting the calculation algorithm specified for the chosen hydrological model, and utilizing rainfall equations from various sources for municipalities within the basin. Although the results indicated a very small variation in precipitation intensity values for Itapecerica da Serra (an increase of 2%), a significant increase (28%) in critical rainfall values was observed for Embu das Artes, demonstrating a noteworthy alteration in the rainfall pattern for this locality. Consequently, the peak flow results followed the same trend. It is noteworthy that, in this modeling, a hypothetical scenario was considered, disregarding the presence of downstream flowregulating structures such as dams. Finally, the I-PAI-WU method proved to be of simple application, requiring basic data such as precipitation intensity, drainage area, runoff coefficient, and spatial distribution factor of rainfall, making it suitable for small and mediumsized basins and short-duration rainfall events.
