Análise de falha em uma série de ligações soldadas de um trecho de tubulação de utilidades para condução de vapor superaquecido
(Universidade Federal de São Carlos, 2021-11-23) Rocha, Frank Simon; Evangelista, Sérgio Henrique; https://lattes.cnpq.br/1610397432103491; https://lattes.cnpq.br/9055375750542920
Process pipes for conducting superheated steam in sugar and energy power plants demand high mechanical strength at high temperatures. The joints between the pipe rod and the connection of this system are mostly satisfied by the welding process, particularized for being single v-groove. Although the performance of the welded connection guarantees mechanical resistance equivalent to the entire tube, a joint is defined as a stress concentrator. Therefore, due to the thermal loads request by the continuous transient regime required by the manufacturing process, the circumferential region that includes weld, Heat Affected Zone (HAZ) and edge metal base is a critical candidate volume to determine the allowable loading and service life of the system. Therefore, this project performs a pragmatic failure analysis in a series of welded connections in a stretch of superheated steam pipe, which suffered longitudinal cracks along the joints. The objective is to identify the mechanisms causing the failures. The results obtained indicated that the thermal expansion of the pipe provided by the operation above the limits adopted in the project can generate stress fields at the material's rupture limit. It was also possible to conclude that the presence of heterogeneities in the weld metal or in the coarse-grained HAZ arising from the manufacturing process can cause nuclear cracks from the deformations generated by thermal loading. Despite the inconclusiveness regarding the mechanism causing the failure, it is possible to say that the results of the study are significant. Furthermore, guidelines were established to perform a second iteration of the failure analysis process aiming at more effective results in future works.
A Agroecologia como elemento pedagógico: uma análise de experiências em escolas de diferentes regiões do Brasil
(Universidade Federal de São Carlos, 2021-11-23) Mendonça, Thamirys Ramos de; Norder, Luiz Antonio Cabello; https://lattes.cnpq.br/0080353709980071; https://lattes.cnpq.br/8131644803309035
Agroecology can be understood as a science and as a practice, connecting itself in different ways with other fields of knowledge. In recent decades, agroecology has been inserted in the educational context at different levels, from basic to higher, technical and technological education. In elementary school, which covers students from 1st to 9th grade, agroecology can be presented as a complementary and multidisciplinary activity, associated with the principles of environmental education, established by the National Environmental Education Policy (PNEA). Experiences in this sense have already been developed in Brazilian schools, aiming to present the concepts and practices of agroecology in a playful and educational way. In this article, we seek to present the results of a literature review that aimed to survey experiences of activities in agroecology in elementary education in Brazil, based on 5 case studies in schools from different regions. Among the practices worked on in schools, the relevance of the school garden as a research and teaching laboratory, as well as composting and seedling production was verified. It was found that, based on such practices, themes such as food safety, healthy habits, environmental preservation, ecology and society could be discussed with the students. It is concluded that, although there is no legal obligation to guide agroecology as a curricular component, this inclusion can bring pedagogical benefits to the school context, as it allows for the discussion of multidisciplinary themes, especially in urban schools, in which the environmental theme is agriculture is not daily present in the reality of the student community. In this sense, the importance of planning activities that is based on the reality of each school is highlighted, which can be done from a Rapid Participatory Diagnosis (DRP) and other participatory methodologies that allow the educator to have a better understanding. assertion of the reality of the student community.

Relação entre a qualidade hídrica superficial e a dinâmica da paisagem em quatro sub-bacias hidrográficas com alta densidade demográfica na região sudeste do Brasil
(Universidade Federal de São Carlos, 2021-11-23) Dorici, Mariana; Almeida, Dayana; https://lattes.cnpq.br/8099346855929913; Moschini, Luiz Eduardo; https://lattes.cnpq.br/2728357583462262; https://lattes.cnpq.br/3342329884412865
The deterioration of water bodies has become an increasingly worrying problem as human activities cause significant changes in the physicochemical properties of water and a series of environmental and human health problems. However, the protection of water quality is still a challenging task for humanity, because the integrity of water resources is associated, in a complex way, with a series of natural and anthropogenic factors and the interactions between them. In this sense, several studies have been carried out in recent years, showing evidence that the landscape structure has a significant relationship with the water quality of surface water bodies. Therefore, understanding the interaction between the landscape structure of a watershed and the water quality of its surface water resources is of paramount importance for watershed management. Thus, this research aimed to analyze the relationship between the dynamics of land use and land cover and landscape metrics with the physical, chemical and microbiological parameters of water, in four hydrographic sub-basins, located in the Water Resources Management Unit of the Piracicaba, Capivari and Jundiaí Rivers (PCJ). Initially, the physical, chemical and microbiological parameters of surface water were analyzed, identifying the variations that occurred in the selected period (2011-2014-2017), this analysis showed that the water quality of the study area underwent significant variations in 2014 and that its deterioration was related to rainfall data. Then, an analysis of the dynamics of land use and land cover and an analysis of the landscape pattern was carried out, pointing out the importance of a joint analysis between these two factors to understand the structure of the landscape and its relationships with other environmental factors, such as, example, water quality. Finally, a statistical analysis was carried out to investigate the relationship between the structure of the landscape and the parameters of water quality, using the redundancy analysis (RDA). The RDA is used to analyze the main causes of data variation, exposing the correlation between the response and its explanatory variables. Based on their results, it was concluded that the land use and land cover class "urbanized areas" was the most relevant and explanatory for the degradation of surface water quality in the study area and the classes "natural vegetation areas" and "continental waters ” were the most related to the pH and nitrate nitrogen parameters. To understand this relationship, the analysis of the landscape configuration and seasonal variations became essential. Thus, it was identified that the IJI, CONTAG and LPI metrics were essential to understand the responses found. These responses showed deficiencies in the management of hydrographic basins and that a series of actions need to be implemented so that decision makers enforce environmental legislation, maintaining the preservation of large forest remnants and the conservation of permanent preservation areas. Emphasizing the need for integrated and continuous analysis and management of water resources, so that planning and responses to critical and adverse situations can be adequate and efficient.
Avaliação de métodos de construção de redes na classificação semi-supervisionada de textos
(Universidade Federal de São Carlos, 2021-11-23) Sabino, Mariana Zagatti; Valejo, Alan Demétrius Baria; https://lattes.cnpq.br/9546164790189830; https://lattes.cnpq.br/9974328567127695
Due to the shear amount of data produced daily in text format, being it publicly on social media or privately inside enterprises, there is a growing need to analyze and extract information from them. The objective is to transform this data into useful tools such as translation systems and virtual assistants. The area of Natural Language Processing, together with Machine Learning, provides the necessary technologies for such objective. One of the most explored tasks in this context is text classification. Between the diverse approaches existing in this area, semi-supervised learning algorithms stand out. Specifically, transductive algorithms, that receive as input data in the form of networks and return labeled data. This strategy needs the initial construction of a network based on the analyzed data, a task for which many algorithms can be used, producing networks with different topological characteristics, interfering directly in the classification accuracy. In this context, the objective of this study is to analyze the influence of network-building algorithms on semi-supervised text classification. An empirical evaluation on real document collections was carried out. The results point that algorithms that generate non-regular networks have a better overall performance, furthermore algorithms that allow the use of the cosine metric, more suitable for text-based data, performed better than those that don’t. These methods are: k-NN, Epsilon, GBLP and Mk-NN.

This work aimed to write and analyze the development of a Sociopraxis Network and a Sociotechnical Network of innovation in medicinal and herbal plants that arises from the collective of women of the Pirituba II settlement to access public policies and the Unified Health System - SUS of Itapeva-SP. The work uses the concepts of agroecology, sociotechnical network, sociopraxis network and public policies focused on agroecology, medicinal and herbal plants and local productive arrangements to present, through the analysis of the timeline and the analysis of the participation of actors, the process of network organization that culminated in the dispensation of medicinal plants in the SUS of ITAPEVA- SP and in the formalization of the organization of women, with the creation, in 2009, of the Cooperative for the Production of Medicinal Plants - COOPLANTAS. Since the author of the work actively participates in the trajectory of the collective of women, since 1998, the work used a methodological theoretical approach that allows incorporating the participant role of the author in the object: documentary analysis, focus groups, poll and interviews. It is expected that the description, reflection and analysis of the process can contribute to the production of knowledge in the area.
Two essays on foreign direct investment and financial market development
(Universidade Federal de São Carlos, 2021-11-23) Scarpa de Mello, Diego; Moralles, Herick Fernando; https://lattes.cnpq.br/3603674784653923; https://lattes.cnpq.br/8591624728612654
Current literature states that Foreign Direct Investments (FDI) is able to induce regional entrepreneurship in the host country. However, few studies have evaluated the interplay among FDI and Financial Market Development (FMD) for the creation of firms within the scope of emerging economies. Thus, we present this study in two parts: (i) through a systematic literature review we analyze the relationship between FDI and FMD, to understand the evolution of scientific publications on the subject, in addition to presenting the main results found and suggestions for future work, (ii) by employing a unique database of FDI in Brazil between 2010 and 2014, our studies aim to shed light on aforementioned issue. We analyzed two relevant dimensions of the financial market: credit availability (depth) and banking branches (access) in the same period. Our findings indicate that regions that combine FDI, depth, and access present a higher, positive impact on the number of new firms, which is a relevant policy implication to encourage local business in emerging economies.

Definição de estratégias de lances de concessionárias de distribuição em leilões de energia elétrica do tipo loose pool baseadas em teoria de jogos
(Universidade Federal de São Carlos, 2021-11-23) Alvarenga, Vinícius Blaya; Lage, Guilherme Guimarães; https://lattes.cnpq.br/4426242038269208; https://lattes.cnpq.br/9517917571245250
Due to the deregulation of the Brazilian Electricity Sector and the definition of the New Model of the Electricity Sector in Brazil in 2004, generation, commercialization and distribution companies have become able to bid supply and demand in electric energy auctions authorized by the National Agency of Electric Energy (ANEEL) and carried out by the Electric Energy Trading Chamber (CCEE) to encourage competitiveness among different companies in each activity. Thus, this paper aims at defining bidding strategies for the purchase of electricity by distribution companies using Game Theory, avoiding their exposure to (generally high) difference settlement prices by the Independent Market Operator (OIM). To accomplish this, it has been implemented an auction model to simulate the supply and demand allocation by the OIM for a 6-bus test-system considering active power balance on system buses and minimum and maximum active power flow limits in transmission lines. As a direct result of the proposed methodology, it is possible to define the best purchase bidding strategies in an auction in terms of the number of competitors and the number of accounted bids.
Revestimentos comestíveis com óleos essenciais na preservação da qualidade pós-colheita de morangos: uma revisão
(Universidade Federal de São Carlos, 2021-11-23) Calisto, Ítalo Henrique; Ferreira, Marcos David; https://lattes.cnpq.br/6652079760634274; Silva, Caio Marcio Paranhos da; https://lattes.cnpq.br/7793686262868668; https://lattes.cnpq.br/4212277504053479
Strawberry is a non-climacteric fruit characterized by its unique flavor, being highly desirable and being a relevant source of bioactive compounds due to the high levels of vitamin C, vitamin E and phenolic compounds, as well as anthocyanins, pigments that give the strawberry its red color and are related to health benefits. The application of edible coatings on the surface of the food is a treatment that allows to increase the shelf life of the food with little effect on its original characteristics. These coatings may contain active ingredients in their composition, such as essential oils that can confer antimicrobial properties to these materials. This study aimed to review the state of the art on the application of edible coatings associated with essential oils in the preservation of postharvest quality of strawberries. The results showed that the application of edible coatings with essential oils can improve the quality parameters of strawberries during storage and control the development of post-harvest diseases. In this way, the application of these materials can be a promising alternative to replace synthetic chemical fungicides for disease control and prolonging the shelf life of strawberries.
Compreendendo o papel da melamina (C3H6N6) no caminho de degradação de compósitos fertilizantes contendo ureia
(Universidade Federal de São Carlos, 2021-11-23) Rodrigues, Joyce Fabiula; Oliveira, Cauê Ribeiro de; https://lattes.cnpq.br/5321313558714462; https://lattes.cnpq.br/1982992558038852
This work proposed a study of new fertilizer composites that have melamine in their composition, a molecule of high nitrogen content (66% total mass) but recalcitrant, observing factors that may influence the effective release of its N as a nutrient. Composites with thermoplastic starch (TPS) matrix of urea and melamine were studied for fertilizer application. The composites (TPS:Ur:Mel 1:2 and TPS:Ur:Mel 2:1) produced were characterized by X-ray diffractometry, absorption in the infrared region and scanning electron microscopy and tested with the presence of microorganisms to study behavior in the presence of melamine. All characterizations indicated the synergy between the precursors in the extrusion process. The urea release tests showed superior results for composites compared to pure urea. In addition, tests with the addition of the microorganisms Trichoderma Harzianum and Acidovorax Citrulli led to a better understanding of the melamine biodegradation process. As expected, the use of microorganisms accelerated the releases, but played an important role in terms of comparison with the use in soils without controlled conditions. The microorganisms adapted to the presence of melamine and the quantitative results of the release of ammonia, ammonium and nitrate gases indicated that the melamine degradation process was probably initiated. Such tests highlighted the efficiency of the use of microorganisms so that the N present in melamine is accessible, and corroborated the ability of controlled release of polymeric composites synthesized with starch matrix
Pedagogia e variação linguística no ENEM: análise de questões da área de linguagens, códigos e suas tecnologias
(Universidade Federal de São Carlos, 2021-11-23) Oliveira, Vitória Rodrigues de; Gatti, Márcio Antonio; https://lattes.cnpq.br/0369563657842763
This work aimed to analyze qualitatively and quantitatively the booklet of languages, codes, and their technologies present in the National High School Exam (ENEM) between the years 2014 and 2019 identifying and emphasizing which and how many were the questions that discuss linguistic variation, relying especially on the theory of linguistic variation of William Labov. After reaching the initial objective proposed for this research, specific ones were unfolded that sought to define what was the variation addressed in the questions in question, what characterizes them, and what were the elements that allowed classifying each question as being a certain type of linguistic variation. In addition, the research also briefly discusses the impacts and controversies that ENEM has, to justify the motivations that led to the choice of it as the test to be examined for this work. Within the limits of the research, it was concluded that in only two years the number of questions on the theme is significant, while in the other years analyzed the number of questions on the theme is statistically lower.

When a child is born it is in the family context that all the firsts references take place. Is where the child will learn and develop his primary social, intellectual and communication skills. Therefore, the family plays a significant social and affective role in this individual's life. The importance of the family for the care and development of a child is unquestionable, as it is in this environment that their first interaction with the world and the education of their social identity begins. A deaf child with hearing parents will be placed in a culture and language that they do not have access to, so the family will have to accept this child and learn about their culture and language so that this individual can develop socially, psychologically and emotionally. The present study aims to identify the researches produced about deaf relatives and sign language, in the portal of CAPES, Scielo and Google Scholar Journals in the last ten years, (2011 - 2021). At the end of the survey, were founded an amount of 21 articles that put in discussion hearing family members with deaf children and sign language. Despite being a low researched topic, studies indicate that early diagnosis with good guidance and professional follow-up with family members it reduces the sense of guilt, thoughts and ignorance about the deaf individual and their culture, being a family network with the necessary guidance and support to respect the language and subjectivity of the deaf individual, improving the affective and family ties that are so important for the full development of the deaf child.
Superando barreiras à integração da cadeia de suprimentos via método multicritério de apoio à decisão
(Universidade Federal de São Carlos, 2021-11-23) Aguiar, Fábio Henrique Lima; Sagawa, Juliana Keiko; https://lattes.cnpq.br/6549481623896786; https://lattes.cnpq.br/9987674322632107
Supply Chain Integration plays an important role of influencing the supply chain overall performance. Business competition is taking place between supply chains instead of between companies individually. Academics and practitioners acknowledge the existing barriers, as well as the enablers to establish Supply Chain Integration. However, true collaboration is not found frequently, and few studies of integration have deeply investigated the reasons for such difficulty. Furthermore, the articles do not explore the partners' differences in perspectives and priorities with regard to integration needs, nor the specific solutions to overcome barriers. This study aims, firstly, to debug supply chain integration barriers, prioritizing the most important ones; second, to identify specific, more practical and more feasible solutions from an integration implementation point of view; and, thirdly, to confront the perspective of different partners (suppliers and the focal company) on barriers and solutions. A qualitative approach was used to identify and prioritize specific solutions for supply chain integration, using the Delphi method, and a quantitative approach to prioritize barriers to integration and weigh the impact of each solution against each critical considered barrier, through the HFLTS method (Hesitant Fuzzy Linguistic Terms Set). The results showed that there are two types of solutions for integration, here called critical specific solutions (which strongly affect a specific barrier) and broadband solutions (which moderately affect several barriers), and that there are differences in perspective between focal company and suppliers regarding the criticality and priority of implementation of these solutions. If the perspectives of different partners are not considered when implementing solutions, individual needs can become misaligned in execution time and priorities, compromising the effectiveness of collaboration. The study differs from others by its originality in considering and analyzing two integration perspectives simultaneously, for presenting a list of specific and concrete solutions to achieve integration (instead of more general guidelines, existing in the literature) and for providing clear guidelines for professionals related to the priorities for implementing the solutions.
Perfil de idosos que buscam vagas para cuidados diurnos
(Universidade Federal de São Carlos, 2021-11-23) Semensato, Carolina Ramos; Varoto, Vania Aparecida Gurian; https://lattes.cnpq.br/7449531039410521; https://lattes.cnpq.br/7286581903238068
Introduction: Aging is one of the biggest public health challenges. It is a heterogeneous, universal, natural, and constant process, inherent to the human condition, characterized by several biopsychosocial changes in people's lives. It is an ascending phenomenon in Brazil and in the world, thus generating new needs and challenges, in addition to reformulations in public policies, aimed at reconciling longevity and quality of life with dignity and respect. Due to the projections of greater longevity in the Brazilian context, it is necessary to allocate resources in places of social support and appreciation of family ties, such as the Day Centers for the Elderly (CDI). CDIs, like daycare units of medium complexity of the special social protection network, are part of the social support network and promote socialization, strengthening the health-promoting mechanism. Objective: To characterize the profile of elderly people looking for daycare vacancies in the context of Long Stay Institutions for the Elderly (ILPI) in two inland cities of São Paulo, as well as the applicant for the vacancy and the reason for such search. Methodology: This is a descriptive, qualitative study with content analysis principles, which were applied in the light of the thematic theoretical framework. The data comes from the database of the research group “Direito, Cidade e Envelhecimento” linked to the Department of Gerontology (DGero) of the Federal University of São Carlos (UFSCar). The work development was organized in 3 stages, the first being the appropriation of the theme and bibliographic deepening with the intersection of descriptors in the selected databases, identifying bibliographic productions close to the subject of the study. The second stage was related to the pre-analysis and initial reading of the data, focusing on the characterization of the general profile of the elderly (gender, age group, marital status), who sought the vacancy, and the reason for the search. The third step concerned the treatment of the obtained results and interpretation. The results indicated 451 scientific productions, of which the reading of titles and abstracts supported the exclusion of 446 due to theme incompatibility, resulting in the identification of 5 scientific articles whose studies were aligned with the theme related to the public profile connecting with the elderly people who seek support from CDI. In addition, it was found that some Long Stay Institutions for the Elderly (ILPI) offer vacancies for the CDI modality. Of the 214 requests for both modalities, 189 (88.31%) were for ILPI and 25 (11.68%) for CDI. Of those for CDI, 23 (92%) were from the city of Araraquara and 2 (8%) were from the city of São Carlos. In both cities, the prevalence was female 18 (72%) with a mean age of 84 years, followed by 7 requests (28%) for males with a mean age of 78 years. As for marital status, widowhood was prevalent in 18 (72%) of the requests. Still, in the family context, it was found that most elderly people have children 21 (84%) and 8 (32%) live alone. According to the applicant, the majority 18 (72%) need small support in daily life and support for mobility. The prevalence of applicants is female 21 (84%), with daughters 14 (56%) married 11 (44%) and an average age of 59 years for both sexes. As for the reasons for searching for the vacancy, the prevalence was related to socialization with 13 (52%), followed by health 8 (32%), safety 2 (8%), and 2 (8%) who did not inform. Discussion and Conclusion: The profile of the elderly person seeking a place for a CDI is predominantly female, aged over 80 years, widow, and partially dependent. About the applicant for the vacancy, most were the daughters for reasons of socialization, assistance in daily activities, and mobility. In addition, the search for CDI in the ILPI modality may indicate weaknesses in understanding the typology of services, or the absence of this type of service in the city, signaling demands for partial care attention that favor the maintainability of the elderly in their family environment as long as possible, mutually benefiting the elderly and their families.
