Estrutura do esmalte humano e sua interface com sistemas adesivos

Esta tese sistematiza uma série de estudos dedicados à compreensão da interface do esmalte e sistemas adesivos. Para tanto, a estrutura da camada aprismática do esmalte em alta resolução pela microscopia eletrônica de varredura foi avaliada quanto a sua continuidade, espessura, distribuição nas faces coronárias e em fossas e fissuras, predominantemente em dentes decíduos não erupcionados. Foi também analisado pela microscopia eletrônica de varredura os efeitos do condicionamento de diferentes tipos de ácido e, em especial, do ácido fosfórico em diferentes concentrações, metodologias e tempos de aplicação. Estes trabalhos permitiram visualizar as principais ações ácidas desmineralizantes e os tipos de retenções no centro ou periferias dos prismas ou em ambas as regiões, bem como a profundidade e forma dos “tags” resinosos com carga e sem carga na intimidade do esmalte. No caso particular da aplicação dos selantes em fossas e fissuras foi também avaliada comparativamente a eficácia das técnicas invasivas ou não invasivas. Os últimos experimentos foram dedicados ao estudo da microinfiltração de diferentes sistemas adesivos e da resistência destes sistemas adesivos na estrutura do esmalte. Novos estudos merecem dar continuidade à linha de pesquisa de sempre priorizando o propósito de vincular os procedimentos aplicados com uma consistente e indispensável fundamentação de pesquisa básica no interesse da clínica odontopediátrica.

Respostas da frequência de braçada e do comprimento de braçada na e acima da intensidade correspondente à máxima fase estável de lactato sanguíneo em indivíduos com diferentes níveis de performance

The main objective of this study was to analyze the behavior of variables related to swim ability at and above maximal lactate steady state (MLSS), performed at continuous and intermittent conditions in individuals with different aerobic performance levels. Participated of this study male swimmers with ages between 20 to 25 years, specialists in events of 400 m, 800 m and 1500 m and open water swims, with at least 3 years of experience in the modality. The individuals performed a maximal 400-m swim test. After this test, they were divided into two groups, in accordance with the speed attained during 400-m swim test: G1 (higher performance) and G2 (lower performance). For the determination of continuous MLSS (MLSSc), 2 to 4 trials of 30-min were performed. For the determination of the intermittent MLSS (MLSSi) 2 to 4 trials of 30-min (12 repetitions of 2 min 30 s, with 30 s of rest) were performed, in constant speed, with the first trial performed at 102.5% MLSSc. Th technical indexes, stroke rate (FB) and stroke length (CB) were determined in all tests. The SR was calculated trough recordings using the time needed to perform five stroke cycles. The SL was calculated dividing the speed by the SR. There was no significant difference on the antropometric characteristics between groups. The speed at and above MLSSc were significantly higher at G1 (1,23±0,05 e 1,27±0,06, respectively) than G2 (1,10±0,06 e 1,13±0,06, respectively). There was significant change in SL and SR in G2. In the same way, there was significant change in SL and SR only in G2, above MLSSc. Similar to continuous condition, the speeds at and above MLSSi were significantly higher in G1 (1,27±0,05 e 1,30±0,05, respectively) do que no G2 (1,14±0,07 e 1,16±0,07, respectively). There was significant change in SL and SR only in G2. There was significant change in SR and SL in both groups above MLSSi. Thus,...(Complete abstract click electronic access below)

For the development of this study will be conducted qualitative research involving literature and area of study research. The technique used for the collection is a questionnaire with open and closed questions. The research subjects students trained by Physical Education Department of the State University of São Paulo - Campus Rio Claro, active in this area of academic formation, with one participant from each Dance Company in each year of existence. Data analysis will be based on the technique of content analysis proposed by Bardin (2010). The results found that the extension projects contribute to the professional acting, because they enable exchange of experience, acquisition and incorporation of new knowledge, different from previously built on a broad vision of dance. This new framework allows the development of education/ teaching/ methodology, enabling the contact since graduating with professional practice and obtaining safety and confidence to act in the labor maker

Implementação de um sistema de informação voltado à sensibilidade ambiental ao óleo do litoral sul paulista e avaliação das ações de resposta a derramamentos de óleo

Oil spills cause serious damage to the cost life and environments. Those impacts affect ecologic and socio-economic resources (like fishing and tourism). Within this background, response actions have two main objectives: the contaminant removal, with the less additional impacts, and enhance environment restoration in order to make this process complete in the shortest time possible. The present work proposes to contribute for the emergency environmental management in cases of oil spills by systematization of relevant information for oil spill environmental sensitivity maps. The next stage was to insert all these data on a geographic database, which allows data access by web. Beside that, this work aimed to recommend suitable clean-up techniques for the ecosystems located on the study area, composed by the municipalities: Praia Grande, Mongaguá, Itanhaém and Peruíbe, belonging to Baixada Santista and Iguape, Cananéia and Ilha Comprida, south cost of São Paulo state. This area is situated between two important Brazilian ports: Santos and Paranaguá, and that make it under considerable accident risks. The results were all data inserted on the geodatabase and available to user recover the information by web consulting. With that, this work wishes to contribute to individual emergencial planning of the region.

Pesquisa e experiência: linhas de fuga e dramaturgia científica

The discussions waged by several authors in the field of philosophy of science about scientificity and scientific work often fall to the shock of Sciences, who had long substantiate their studies from the perspective of Natural Sciences. Fact that the man away from research, transforming it into a simple object of study. Among these questions, it is necessary to think in a very scientificity of the humanities, which considers the various types of knowledge that makes up the formation of the individual. In this way, approaching the experience, treated by Agambem Benjamin Larrosa and the educational research with children presents itself as a chance to rethink the current paradigm of Sciences. This gives rise to the objective of this work reflect, based on a research conducted with children and imagetic production, the idea of 'research and its relation to the concept of experience'. We will take as its starting point the elaborations on this concept as presented by Giorgio Agamben. We are assuming that the images of that research, are configured as research papers or research and, in this sense, the research is defined as a documentary research

No resumo de um só dia: tempo e memória em O burrinho pedrês de Gumarães Rosa

Memory, the ability of keeping and remembering past states of consciousness and everything that could be associated with them, is one of the human properties responsible for the construction of experience, knowledge and preservation of individual’s identity. However, recalling is also the way we keep relationships with time, factor that is essential and inherent to our existence and responsible for the fact that we have memory. As for the narrative, as for life, time is a prime category, because it is in time that narrated or experienced events happen. This relationship between time and memory is remarkable in “O burrinho pedrês”, Guimarães Rosa’s short story present in his debut book, Sagarana. In this story, we can notice, generally, the characters use memory as a way to return to the past, evoking, consciously or unconsciously, the experience and its result, the wisdom, to help on the understanding of present situations. So, this research has as objective to analyze how time and memory relate and become indispensable to the development of the narrative and to the construction of the other categories - character, narrator and space. The theoretical foundation is based on studies clustered in three dimensions: a) theoretical essays about Guimarães Rosa’s work in general and the particular short story b) philosophical and/or psychological propositions about memory and time, and c) propositions about the mentioned categories of narrative

Percepção do enfermeiro quanto a sua satisfação no contexto de trabalho em um hospital estadual

With the increasing competitiveness of organizations in search of customers, it is essential that the pursuit of quality becomes a prerequisite for the survival of healthcare organization, is necessary to have working conditions that encourage both personal and professional satisfaction. This study aims to investigate the perception of nurses regarding their satisfaction in the context of work in a State Hospital and contribute to the reflection on the internal customer satisfaction as an important indicator of quality of health services that interfere with quality of care. We used the qualitative method, on phenomenology, with nurses from a state hospital that had at least one year of experience in the institution. Through interviews, it was revealed that satisfaction is related to the literature and is influenced by factors such as human resources, practice nurses, Teamwork, Perception of the patient, professional recognition, physical and material resources and rewarding work, and these themes unfold quality and satisfaction both personally and for organizations

Aplicação do AHP em um caso de escolha dos modais de transporte para a movimentação das partes de um aerogerador

Wind power is a type of energy that is still not too explored in Brazil and, because of the lack of experience in projects of this size, there are still some problems during the stages of planning and execution of wind farms projects. One of these problems is related with the parts’ transportation logistics, since these parts are difficult to transport, because of their length, weight or shape. Furthermore, another aggravating factor is the lack of options regarding to the transportation modals that are available to do the route between the manufacture place and the project site. To help in the decision-making process about the ideal transportation configuration, aiming to reduce the dependence of the logistics’ coordinator, it was chosen to use he AHP method to compare some criteria that have influence in the modal’s choice process. The criteria, determined by the members of the company’s logistics’ department, are: transportation costs, transportation time and the risk of causing damages to the cargo. The results shown by this model, using theoretical background, that standardize the processes related to the modal’s choice
