Wood presents several advantages when compared with other materials employed in the civil construction sector. In Brazil, the standard ABNT NBR 7190: 1997 establishes test methods to determine physical and mechanical properties. However, tests demands procedures on specialized and high-cost laboratories. The Brazilian code displays different values for relations between shear strength and compression strength parallel to the fibers. This study aimed to investigate, considering the results of the compressive strength and shear strength parallel to the fibers tests, the relationship between these properties obtained with the statistical assistance of least square method and considering ten hardwood wood species. The results were compared with the relationship values disposed on the Brazilian Code ABNT NBR 7190:1997, being the greatest coefficient found 86,4% higher than the coefficient presented by the Brazilian code, considering the set of all species. Regarding the variation of the relationship between the investigated properties, considering the different classes of wood resistance, no study was identified that decreases in the values of the greatest coefficients as the classes increases, a situation that ABNT NBR 7190: 1997 exposes in its text, thus presenting another divergent result.

(Universidade Federal de São Carlos, 2019-08-12) Biliatto, Victor Sandrin; Moonens, Laurent; https://lattes.cnpq.br/0480536204428583; Picon, Tiago Henrique; https://lattes.cnpq.br/7853908129934448; https://lattes.cnpq.br/6295450179617895
In this text we study some results obtained by Nguyen Cong Phuc and Monica Torres in the paper "Characterizations of the Existence and Removable Singularities of Divergence-measure Vector Fields" regarding the characterisation of solutions and removable singularities of the equation div F = u, where u is a measure and F is a continuous or Lp vector field. To perform this study, the text presents definitions and properties on divergence-measure vector fields, Hausdorff measures, Sobolev capacity and functions of bounded variation.
Panorama nacional dos estudantes público-alvo da educação especial na educação superior
(Universidade Federal de São Carlos, 2019-08-12) Rocha, Luiz Renato Martins da; Lizzi, Elisângela Aparecida da Silva; https://lattes.cnpq.br/8487600124864253; Lacerda, Cristina Broglia Feitosa de; https://lattes.cnpq.br/9468232016416725; https://lattes.cnpq.br/4901568089807470
The target group of learners with special educational needs (SEN) in Higher Education totaled 37,927 of the 8,027,297 enrollments in 2015, corresponding to 0.47% (INEP, 2015b). It should be noted that, despite the small percentage, this public has been growing significantly in Higher Education in recent years, which indicates the constant need to create even more effective policies to guarantee access: admission, stay and institutions of higher education (HEI). In this sense, the data collected in the present research provide indications of how the Special Education in Higher Education in Brazil offers an opportunity for revision and orientation regarding the recognition and registration of SEN students in the Higher Education Census. Thus, we aimed to analyze and map SEN students in Higher Education in Brazil, taking as a data source the year 2015 and, more specifically, presenting a panorama of Higher Education based on the microdata of the Higher Education Census. In order to reach the proposed objective, we carried out a quantitative research with a descriptive and exploratory method. Data were processed using the SAS® program (Version 9.2) and software R (Version 3.3.1), which enabled access to the microdata through tables. Through Microsoft Office Excel®, the graphs and other tables were assembled, as well as the verification of the values found. As we understand that behind each of these numbers there is a life story, we perform its interpretation in the light of their interaction with the historical and social context. We also identify the imprecision of various data, usually due to misunderstandings in the collection of information (which may be caused by self-declaration or by those who feed such data in the INEP system), or by the impossibility of correcting data once informed and published, which generates distortions of information in relation to reality. In addition, despite the limitations of the data, it is clear that the SEN students are disadvantaged in relation to other people, since the conclusion of the course is still a challenge to be overcome, and access has been restricted to a small portion. For a better overview of Brazilian Higher Education, it is necessary to construct a data collection instrument at the national level, so that, at the time of the student's enrollment in the IES, all the information related to their condition is duly considered and the data presented in the Census indeed express a reliable picture for the construction of public policies.
Registro em prontuário: compreensão do processo de ensino aprendizagem no âmbito da Terapia Ocupacional em contextos hospitalares
(Universidade Federal de São Carlos, 2019-08-12) Bombarda, Tatiana Barbieri; Joaquim, Regina Helena Vitale Torkomian; https://lattes.cnpq.br/7719481657895650; https://lattes.cnpq.br/8070700589653226
The medical record, designated as a collective construction derived from multiple specialized registries, shows the assistance procedures performed and aim at improving the quality of attention to the user. In Occupational Therapy, the medical records aim to reflect the professional reasoning and chronologically enable the visualization of the course of the therapeutic intervention and the occupational performance of the patient throughout the care process. Despite the great importance, the record in medical records presents as an unexplored topic in the scientific field of the Brazilian Occupational Therapy. With the objective of identifying and understanding the teaching-learning process of the medical records in the hospital context existing in the undergraduate courses in Occupational Therapy in Brazil, this quantitative-qualitative study was delineated in two stages: a) documentary research - that consisted in the survey and analysis of documents referring to theoretical disciplines and of professional training of hospital contexts offered by undergraduate courses in Occupational Therapy in Brazil, b) field research - application of an online questionnaire with teachers responsible for occupational therapy disciplines in hospital contexts and students in the practice of a vocational training in the hospital. The data obtained were analyzed by descriptive statistics and discourse of the collective subject. As results, it was verified that the analyzed documents do not gift contents that sustain the practice of documentation, however, students and teachers generally signal, to carry out assessment, intervention and discharge records in accordance with the items recommended in legislation. As fragile aspects of the records, the occupational therapeutic diagnosis and the prognosis were identified. It was verified that the process of teaching-learning of the record in the medical record occurs mostly linked to the activities of professional training, which can be problematic when observed the information that not all students practice internship in the hospital field and that there are students who have access only for medical records. The main teaching-learning strategies employed in undergraduate courses were the discussions of clinical cases and supervised practices, with the main difficulties encountered in this process being the difficulty of access to the medical records, coupled with the dynamics of the service and the lack of standardization in the terminology of the profession. It is believed that the low frequency of insertion of information on prognosis in the medical record correlates with the specificities of the hospital field and that the scarce insertion of the occupational therapeutic diagnosis is linked to the absence of national discussion about this elaboration. Regarding the teaching strategies adopted, it is believed that these are aimed at instigating the development of professional reasoning and reflective critical capacity in relation to intervention, a factor that may contribute to the qualification of the medical record, given the better perception of the role of the occupational therapist and his praxis in the hospital. It is concluded that in general there are weaknesses in the teaching-learning process of the record in medical records, a factor that demands investments in the qualification of training for the documentary practice, which will favor better recognition of the profession

(Universidade Federal de São Carlos, 2019-08-12) Santos, Tamires Cristina dos; Cohn, Clarice; https://lattes.cnpq.br/1714080901123094; https://lattes.cnpq.br/9141182153364129
The Law and Directives for the Brazilian Educational System (Lei de Diretrizes e Bases da Educação Nacional/LDB), promulgated on December 20, 1996, which establishes national educational guidelines for the contents of the curricula of the public and private schools network in Brazil, was amended by Law 10.639/2003 and subsequently by Law 11.645/2008, establishing respectively the obligation to teach and learn about the History and Culture of Afro-Brazilian, African and Indigenous Peoples of Brazil in Basic Education. This ethnographic research sought to establish a dialogue with different agents who, directly or indirectly, were part of the process that established the law 11.645. From the fieldwork carried out at SECADI / MEC with its Technicians in Educational Affairs, documents collected in the MEC, and conversations with Indigenous leaderships, the aim was to learn about different discourses and practices that are mobilized around the law.
Selective laser melting of a biocompatible Ti-35Nb-7Zr-5Ta alloy
(Universidade Federal de São Carlos, 2019-08-12) Batalha, Rodolfo Lisboa; Gargarella, Piter; https://lattes.cnpq.br/4641435644243916; Kiminami, Claudio Shyinti; https://lattes.cnpq.br/5443002033733395; https://lattes.cnpq.br/7468067243817337
Neste trabalho, estudou-se uma nova rota de fabricação de peças de uma liga biocompatível. Assim, uma liga Ti-35Nb-7Zr-5Ta (% em peso) biocompatível foi processada por fusão seletiva a laser (FSL). Os principais parâmetros de FSL foram determinados para a liga, expandindo o portifólio de materiais fabricados por FSL. Considerando que a composição da liga estudada era relativamente nova quando se trata de FSL, algumas amostras foram produzidas por fundição em coquilha de cobre. As propriedades do pó da liga foram analisadas e trilhas simples foram depositadas de forma a definir o melhor conjunto de parâmetros para produzir amostras compactas com densidade relativa de 99,0%. As características microestruturais das amostras da liga TNZT produzidas por FSL foram investigadas, e observou-se uma estrutura de solidificação colunar-dendrítica, enquanto nas amostras fundidas se obteve uma estrutura dendrítica de grãos equiaxiais. Uma estrutura monofásica Ti-β foi identificada nas amostras de FSL, enquanto que uma matriz de Ti-β com ripas de martensita α” foi observada nas amostras de fundição. A análise EBSD das amostras construídas por FSL mostrou grãos colunares crescendo epitaxialmente através de várias camadas, com direção preferencial do crescimento de grãos, diferentemente da estrutura de grãos sem orientação preferencial observada nas amostras de fundição. As amostras de FSL apresentaram resistência mecânica ligeiramente inferior do que as amostras fundidas em coquilha, relacionado a estrutura de grãos nas amostras produzidas por FSL. A formação de textura cristalográfica foi avaliada por meio da construção de cilindros por FSL com diferentes orientações, resultando em estruturas distintas de grãos e texturas cristalográficas. Em seguida, alguns protótipos foram fabricados, comprovando a viabilidade de fabricar peças de uma liga biocompatível com geometria complexa pelo FSL. Finalmente, foi proposta uma alternativa para maximizar as propriedades pseudoelásticas da liga Ti-35Nb-7Zr-5Ta (% em peso), e uma abordagem inovadora é proposta com a formação de uma estrutura oligocristalina, combinando manufatura aditiva a um tratamento térmico isotérmico simples.
