A remoo da smear layer um procedimento importante para a regenerao periodontal e para o tratamento da sensibilidade dentinria. Diversos tratamentos tem sido realizados para sua remoo, porm, mostrando resultados conflitantes ou insatisfatrios. No presente estudo nos propomos a analisar atravs do microscpio eletrnico de varredura a eficincia dos detergentes: lauril sulfato de sdio, Plax e de mamona assim como o EDTA 24% na remoo da smear layer. Todos os produtos testados foram aplicados com bolinha de algodo, renovada a cada 30 segundos, a qual era esfregada na superfcie radicular por diferentes perodos. As fotomicrografias foram analisadas atravs da aplicao de um ndice de remoo da smear layer por trs examinadores calibrados e os resultados analisados estatisticamente. De acordo com nossos resultados pudemos chegar as seguintes concluses: 1- a instrumentao com curetas de Gracey provocou a formao da smear layer; 2- o detergente lauril sulfato de sdio no removeu a smear layer, tendo sido o pior resultado entre os detergentes testados; 3- Os detergentes Plax e de mamona mostraram resultados semelhantes entre si e superiores ao controle negativo e ao lauril sulfato de sdio, porm, no removeram a smear layer satisfatoriamente; 4- O EDTA 24% neutro mostrou ser eficiente para a remoo da smear layer.

This project developed microstructural characterization technics of commercial dualphase and multi-phasic (TRIP) steels that were provided by the automotive industry and are currently used as the raw material for the production of automobiles. Inserted in this context, there is the development of the advanced high strength steels in consonance with the ULSABAVC project, which aims the production of safe, economically viable and efficient in terms of fuel consumption vehicles for the 21st century. The micro-structural characterization of biphasic and multiphase steels was done by the identification and quantification of the coexistent phases. In this item, a special attention was given to the technics that were performed using optic microscopy and scanning electron microscopy. An important contribution to this work was the utilization of different alternative chemical reagents (Beraha, Heat-Tinting technics) in addition to the classical ones (Nital and LePera)already used conventionally by the UNESP's Group of Mechanical, Microstructural and Fractografic Characterization of Materials. The revealed microstructures were correlated with the materials' mechanical properties determined through traction tests, such as ultimate tensile strengths, yield strength and stretching important since the material has structural application in the automotive industry. As a result, it was observed the superiority concerning the studied mechanical properties for the biphasic and multiphasic steels when compared to the conventional carbon steels. Besides, it was perceived a large potential for the industrial scale utilization of the Heat Tinting technics in this field, seen its differentiation of the existent phases and easy reproducibility

This paper aims to base the thesis that the varied currents of the post-modern thought, in so far as have recourse to relativism to a greater or lesser degree, contribute to the legitimation of the religious education in public schools and, in a broader aspect, the religion in the public spaces. The methodological resource used to demonstrate the link between post-modern thought and religious education is the analysis at the historical and dialectical materialism perspective of publications produced to increase teachers on this discipline that is, in compliance with the Constitution, optional for students and mandatory for public elementary schools. The subject of this analysis is the learning content and has as prime concern to highlight the discourse of legitimation recurrent in authors when it is explicit in itself and explicit when it does not. The religious education in public schools as object of study allows us to understand the relationship between the post-modern thought, with its hegemony space within the human sciences and contextualized in the neoliberal economic environment, and the learning to learn pedagogies currently hegemonic in the educational landscape. We intend to contribute to the legal debate on laity, the philosophical debate on post-modernism and especially to the debate on the pedagogical theories in the educational fundaments.

The present article aims to elaborate an objective analytical panel, initially from the 1920- 1930 when Luiz Igncio Romeiro de Anhaia Mello, cathedratic in the urban question, started to quote a series of authors and American plans as references to their reflections, mainly when the point was the verticalization or not at So Paulo City. From a broad bibliographic research with the systematization of the register from the debate between Anhaia Mello, this article intends to point out how the transposition of the urbanistic conceptions to the academic environment happened and, at the same time, the legal normatization of the So Paulo City that resulted in the creation of a draft of the regulations for use and occupation of the soil. The systematizations and analysis were based in a broad reading of the bibliography and documental sources that refer to the proposed theme. The books of the library of FAU-USP, specifically the one from SAGMACS Sociedade de Anlises Grficas e Mecanogrficas Aplicadas aos Complexos Sociais ( Society of Graphical Mechanical-Graphic Analysis Applied to Social Complexes) -, aiming to select papers and the collection of Anhaia Mellos family, so that a reconstruction of the intellectual and professional journey of the Urbanism Professor. The systematization of the collected data and posterior comparison with the bibliographical study was fundamental for the reconstruction of the reflection of Anhaia Mello about the ways of the urban streets and roads at Sao Paulo City should be lead to on the middle of the XX century having as a guideline the debate between Anhaia Mello very common on the 1950s for less important countries when dealing with the organization of the size of industrial metropolis. It was possible to identify the crystallization of one urbanistic proposal for the city: the from Anhaia Mello, that bet on the reversion of the metropolitan cycle by stopping the urban growth by the application of the theoretical conception of the garden city.
