Variação sazonal da composição corporal de lagartos teiús (Salvator merianae) utilizando a técnica não invasiva Absorciometria de Raios-X de Dupla Energia (DEXA)
(Universidade Federal de São Carlos, 2022-02-21) Carabolante, Tiago Fabricio; Bícego, Kênia Cardoso; https://lattes.cnpq.br/0169967378071426; https://lattes.cnpq.br/9092204254024834
The significant reproductive investment in spring, preceded by metabolic and activity reduction during winter hibernation and followed by high summer activity in Salvator merianae, must be accompanied by important changes in protein, lipid and bone mineral body composition. Non-invasive techniques for measuring body composition are essential for longitudinal studies of life history, and the relationship between body condition and physiology, in addition to the consequent reduction in the number of experimental animals. Dual energy X-ray absorptiometry (DEXA) is a non-invasive measurement technique that provides values of bone mineral content, lean mass and fat mass. This technique is widely used to determine the body composition of humans, as well as other mammals and birds, but its use in lizards is poorly understood, requiring validation. Therefore, the objectives of this study were: i) to validate the use of the DEXA technique, from the comparison with direct chemical analysis, to measure each component of the body composition of S. merianae lizards; ii) to determine the seasonal variation of the body composition of S. merianae from DEXA scans repeated in each season of the year. Our results show a strong correlation between the values obtained by the predictive mathematical models and values observed in the chemical analysis (r values between 0.95 and 0.99) without significant differences between the means. The results indicate changes related to the use of lipid energy reserves to meet the reproductive demand in males and females, with possible recruitment of bone calcium sources by females in egg production. Therefore, we conclude that the DEXA technique presents itself as a potential and excellent tool for measuring the body composition of tegu lizards, enabling the construction of mathematical models with high predictive power for body components and highly related to the life history of the species. With the successful validation and application in a study of seasonal variation, the use of DEXA seems to be very promising in the performance of longitudinal studies that evaluate patterns in the variation of body composition that are related to morphophysiological and bioenergetic changes, in addition to knowledge about the ecology and the life history of the species.
MOVA: uma análise bibliográfica de seus 30 anos de (re)existência
(Universidade Federal de São Carlos, 2022-02-21) Zacharias, Maria Alice; Braga, Fabiana Marini; https://lattes.cnpq.br/1103496815216263; https://lattes.cnpq.br/9153013952010960
The present research has as its object of study the bibliographical research of the Youth and Adult Literacy Movement (MOVA) in the years 1989 to 2019, in order to understand what the academic publications of the national bases about MOVA point out, what its limitations and the elements that have kept the program active for three decades. In addition, we sought to find out if there is an announcement of emancipatory practices and/or policies that can contribute to the development and improvement of popular education and the education of young people, adults and the elderly. adapting to different contexts and, as it has humanistic and popularly based characteristics, subjects bond more easily in relation to formal education, following an active program. For this, bibliographical research was used according to the conception of Salvador (1978) and the communicative methodology (GÓMEZ et al, 2006) for data analysis, based on Paulo Freire's theory of dialogicity (1999) and on the theory of action communication by Jürgen Habermas (1989). The results refer to the collection made in the national bases, specifically the BDTD and CAPES, and indicate a great concentration in the master's research carried out in the State of RS and SP based on different themes such as curriculum, teacher training, pedagogical practices and public policies, but which mostly indicate the lack of legal support in youth and adult literacy, demonstrating the need for effective strategies to really include youth and adults in educational and training processes.
O relato de experiência e a formação docente: mapeamento de dissertações e teses (2012 a 2021)
(Universidade Federal de São Carlos, 2022-02-21) Marcelino Lanfranco, Áurea Cristina Pires; Fortunato, Ivan; https://lattes.cnpq.br/8293044394759438; https://lattes.cnpq.br/7925903188660082
When we looked for the experience report as a methodology in the CAPES Theses and Dissertations Catalog database, we did not find any work that has mapped the trends of experience reports that are found in the area of education. Therefore, this research aims to defend that the experience report is a research methodology in education. The general objective of this research is to map the theses and dissertations, developed in Brazilian postgraduate courses, which describe experience reports developed in the classroom. The specific objectives are: to analyze the dissertations and theses, which used the experience report as a methodology; how they are being described; and finally, how these descriptions impact the continuing education of the teacher who intends to reproduce this report. This dissertation focuses on the continuing education of teachers, specifically in classroom work, where their experiences and relationships with other more experienced professionals contribute significantly to teacher education. Research that maps productions can significantly contribute to the constitution of the research field, in this case, teacher education. This dissertation is a research that brings results from the State of Knowledge, as the mapping is centered on theses and dissertations. The question that guided this work was “How is the experience report in the training of teachers in Brazilian postgraduate courses treated?”. Talking with the authors Dubar (2005), Fortunato (2018;2021), Nóvoa (2017), Perrenoud (2000), Tardif (2017) and Xavier (2014), it was possible to think, within the postgraduate academic environment, of the reality continuous training of teachers through teaching practice. Specifically in how the experience report contributes to the training of other teachers who will read the report and with the one who is reporting, with the possibility of reflecting on their own practice. Research has shown the following results: many researchers describe themselves in their reports, that is, it is not known the formation or area of activity of the teacher who wrote the research. Another result is the lack of description of the planning, so it is necessary to verify what was the plan initially outlined and whether it was possible to execute it or not. If not, it is important to describe the reasons.
Análise da influência da vibração de máquina na qualidade do acabamento superficial e no surgimento de delaminação durante o fresamento lateral de laminados de CFRP (Carbon Fiber Reinforced Polymer)
(Universidade Federal de São Carlos, 2022-02-21) Camargo, Wesley Soares; Shiki, Sidney Bruce; https://lattes.cnpq.br/0573973677787523; Barbosa, Gustavo Franco; https://lattes.cnpq.br/4027686840017498; https://lattes.cnpq.br/8312795150565421
The use of composite materials in the manufacture of products has grown in several sectors of the industry, which promotes research and development aimed at the improvement of these materials. However, the machining conditions imposed in the manufacturing process of a material are determining factors in the final quality of the product, due to structural changes resulting from cutting forces, vibrations and temperature, in addition to other interference generated by the process in the surface finish of the machined part. . Thus, the research project in question proposes a comparative study through combinations, involving different rates of feed speed during the machining process used in the milling of parts in CFRP laminates, a material widely used in the aeronautical manufacturing industry. Analyzes were carried out regarding the integrity of the CFRP laminate, in relation to the surface finish and delamination conditions of the composite, caused by the imposed machining conditions. At the same time, the level and characteristics of the mechanical vibration exerted in the milling were monitored, according to the different parameters of feed speed adopted, in order to allow a correlation between the different variables applied in the process. CFRP laminated specimens were milled at different feed rates keeping constant rotation, on a Romi D800 CNC machining center. During the milling process, mechanical vibration signals were captured with a MEMS ADXL335 triaxial accelerometer fixed to the milled part. A rhombic-type end mill was used during machining. To evaluate the structural results obtained on the machined surface of the milled parts, the scanning electron microscopy technique was used, showing the best finish of the machined surface with higher cutting feed rates.
Avaliação da viabilidade do uso de redes neurais artificiais para o desenvolvimento de um softsensor de biomassa de microalgas em fotobiorreator
(Universidade Federal de São Carlos, 2022-02-21) Palma, Guilherme Meneghetti; Horta, Antonio Carlos Luperni; https://lattes.cnpq.br/5923938048634505; https://lattes.cnpq.br/5582496658768821
Microalgae are natural sources of biomass, unsaturated fatty acids, carotenoids, xanthophylls, vitamins, proteins, minerals and enzymes; compounds of great commercial importance. Furthermore, since biofuels have become a product of great interest to industry, especially in the energy sector, the production of microalgae has come to be widely explored by scientific institutions and private organizations. In addition to being one of the most photosynthetic efficient organisms, it requires a very small cultivation space when produced in bioreactors. Thus, the optimization of the microalgae production process in photobioreactors is of great economic interest. Currently, the measurement of biomass values and cell concentration inside reactors is one of the major limitations for the optimization and control of the process, after all, it occurs in a non-automated way by cell counting and dry mass determination methods. Therefore, the objective of this project was to evaluate the feasibility of using artificial neural networks to create a biomass instantaneous inference softsensor inside a bioreactor from light intensity data obtained by red, green and blue light sensors connected to a microcontroller. The study was carried out by cultivating the microalgae Scenedesmus obliquus in modified BG-11 culture medium in a 6L Airlift-type photobioreactor with illumination provided from a white LED panel. The content presented in this study showed artificial neural networks with MSE = 0,0278 [mg/L]2, R2=0,93 and provides substantial information for the accomplishment of the control and optimization of microalgal production inside bioreactors based only on light intensity information.
Saberes geográficos compartilhados por professores dos anos iniciais do ensino fundamental na rede de aprendizagem e desenvolvimento da docência (READ) da UFSCar
(Universidade Federal de São Carlos, 2022-02-21) Gracioli, Jéferson Muniz Alves; Anunciato, Rosa Maria Moraes; https://lattes.cnpq.br/3064136997342775; https://lattes.cnpq.br/1430569136446167
The research aimed to analyze how experienced teachers, beginners teachers and graduated teachers share geographics knowledges through intergenerational dialogue in ReAD (“Rede de Aprendizagem e Desenvolvimento da Docência” in Brazilian Portuguese, which means Teaching, Learning and Development Network). The research was carried out in an online collaborative group. The activities was realized through the creation of two groups called “Geography: learning how to read the world”, given in a free way in the 1st and 2nd semesters of 2019, with the purpose to promote changes experiences between the subjects. Data were extracted in dialogues shared with the participants, discussion forum reports and other productions in virtual learning environment. It used the ATLAS.ti analyze software to help systematization and data coding. The research presents a qualitative approach - world´s interpretive to understand the phenomena considering the meaning that people confer to it, and collaborative, because it was part of a reciprocal relationship considering professional development between beginners teachers, experienced teachers, graduated teachers and tutors. Four groups of analyses categories were established: Memories related to the professional development of primary school teachers that are ReAD´s participants; Geographics knowledges structured in intergenerational dialogues about Geography in primary school; Strategies and proposals to improve the education based on ReAD´s participants places representation and landscapes and The ReAD as a propelling online formative development for teachers in primary school. The results highlight the importance of the online intergenerational dialogues to share/exchange experiences, practices, difficulties and learnings for the teacher professional development. The research indicates that in teachers development there is an insufficiency deepening of geographic knowledges, hampering the strategies expansion and proposals for teaching practices. Finally, the ReAD´s impact as a propelling of formative actions and reflections contributes to diminish the difficulties that teachers face in their performance. In conclusion the attention of geographic knowledges in primary school allows the construction of distinct perspectives and comprehensions about educational contents with students´ background.
Representação parental sobre a criança com altas habilidades ou superdotação
(Universidade Federal de São Carlos, 2022-02-21) Braz, Paula Paulino; Rangni, Rosemeire de Araújo; https://lattes.cnpq.br/6399149504309769; https://lattes.cnpq.br/7708298574440290
The family institution is the first social nucleus present in the life of the individual and contributes fundamentally as a central reference point in the process of human development. However, since it is formed by several members that acts in its subjective constitution, it is recommended that investigations involving the family delimit the focus on existing relationships. For this reason, the intention of this research was to investigate the representations about giftedness through the parental figure, that is, the father, mother or other responsible adult, who assumes the role of ensuring the care, education and development of children. Assuming that raising a child with atypical development is a challenge, the guiding question of the research was: what do parents think about the giftedness indicated in their children? The main objective was to know the parental representation about the giftedness displayed in their children. The specific objectives were: a) to verify and analyze the meanings attributed by the participants to the giftedness and; b) to point out how the parental representation about the giftedness can interfere in their children's lives. For this purpose, the research was set up with a descriptive approach and adopted the Collective Subject Discourse methodology for the treatment of the data collected in a qualitative and quantitative way, describing the individual’s thoughts collectively and evaluating the degree of sharing and distribution of this thought in the group. To collect the data, the semi-structured interview was used and the sample consisted of nine (9) mothers of preschool children with giftedness. The results indicated that parents' representation about giftedness involves knowledge produced by common sense, which changes in relation to the identification of giftedness in the child. Feelings such as fear and worry are present in the lives of these parents, especially by comparison with personal experiences lived, which may interfere with the child's education. Furthermore, it was possible to verify from the selected sample the recognition of characteristics of giftedness by the participants in themselves and in close relatives after the identification of the children. The social relevance of the research is justified by the importance of the family in the education and socio-emotional development of children. Thus, knowing the aspects involved in having children identified with high potential can contribute to advances in the field, in addition to guiding the development and implementation of work involving preschool children indicated with giftedness and their family, in schools and centers and associations that serv this public.
Apartidarismo ou apolítica (2002-2018): uma análise sobre o comportamento e as atitudes dos eleitores não partidários
(Universidade Federal de São Carlos, 2022-02-21) Jaeger, Rafaella Lopes Martins; Braga, Maria do Socorro Sousa; https://lattes.cnpq.br/2311094074614215; https://lattes.cnpq.br/2315282054349295
The main objective of this study is to understand the behavior and attitudes of non-partisan voters. For this analysis, we will seek to understand the behavior in relation to the relevance of this voter's vote to break the pattern of electoral competition dominated by PT and PSDB. And the analysis of attitudes in order to investigate the view of the non-partisan voter who is less educated and who has no interest in politics regarding the vote for Jair Bolsonaro in 2018. The main hypotheses are: the change in the voting pattern affected the break of the PT-PSDB bipartisan pattern and the profile of the apolitical independent is more susceptible to anti-democratic and anti-systemic appeals. In order to confirm or not these answers, the electorate was segmented based on Russell Dalton's Theory of Cognitive Mobilization (2013), which typifies the electorate into four electoral profiles, namely: cognitive partisans, ritual partisans, nonpartisans and independent apolitical, focusing on the last group. This is because, according to Borba, Gimenes and Ribeiro (2015), it would be this segment, formed by low education and low interest in politics, that would represent most Brazilians. The work was divided into three chapters: at first, the theoretical and conceptual construction of the research was presented; then, we discussed the methodological aspects based on data from the Brazilian Electoral Study (ESEB), referring to the 2002, 2014 and 2018 elections; and finally, the results were analyzed in three sections: i) the indices of the variables that make up the theory of cognitive mobilization over the years analyzed; then, ii) the aspects of the vote of voters were indicated based on the typology presented in the highlighted years and, finally, iii) the vote for Jair Bolsonaro among the apolitical independent voter in the 2018 election was investigated more deeply, profile that poses the greatest risk to democracy. It is concluded that the break of the PT-PSDB pattern was not an unexpected rupture, the vote of the non-partisan voter was important for the result of the 2018 election and, therefore, for the victory of Jair Bolsonaro, especially among apolitical independents, thus confirming the main hypotheses of this dissertation. In addition, it was demonstrated that antipetismo had a strong influence on the result among nonpartisans.
