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.

Essa pesquisa teve como objetivo discutir e analisar a questo da incluso escolar tendo em vista explorar a produo acadmica a respeito da temtica a fim de comparar as tendncias metodolgicas de estudo e relatar as evolues histricas ao longo desde a dcada de 90. Para isso, o presente trabalho est estruturado em trs captulos: o primeiro uma breve retrospectiva histrica cultural entre deficientes, escola e a sociedade; o segundo sobre a formao continuada e inicial do professor inclusivo e o terceiro descreve os resultados do levantamento bibliogrfico realizado na base de dados online da UNESP, considerando trabalhos de concluso de curso, dissertaes e teses defendidas entre 1990 e 2013. Os dados coletados foram analisados qualitativamente, com alguns resultados quantitativos. Aps a coleta de dados, os trabalhos foram analisados com base nos seguintes critrios: objetivos, local da pesquisa, tipo de delineamento, instituto onde o trabalho foi apresentado, principais resultados, instrumentos e tipos de participantes (quando configurar uma pesquisa emprica). Pretendeu-se verificar, se existe uma tendncia na metodologia de trabalhos cientficos em relao a esse tema, de pesquisas mais de cunho bibliogrfico ou emprico, dado a sua complexidade

The development of electrocatalysts for the oxidation of methanol and ethanol is very important, because these alcohols may be used in the anode fuel cells which convert chemical energy directly into electrical energy with high efficiency, cleanly and with low noise. Thus, this study reports to the synthesis of nanocatalysts of PtAu supported on carbon by microemulsion method. The physical characterization of these catalysts is performed through the techniques of X-ray diffraction and transmission electron microscopy. The catalytic activity of the prepared materials was studied using conventional electrochemical techniques and also the technique of spectro-electrochemical in situ FTIR, which allows identification of intermediates and products of the reactions. From the x-ray diffraction, it was observed that the thermal treatment applied to catalysts favored incorporation of Au into the crystal lattice of Pt,that is, increased the formation of PtAu alloy. Micrographs indicated particle size about 3 nm to materials not heat treated and 9 nm to materials subjected to thermal treatment (heating at 150 C for 1h and 30 min in argon atmosphere). Current density oxidation of methanol on PtAu / C were superior to pure platinum. Spectroscopic results indicated the presence of formate in solution in 50:50 and the composition showed bands for CO2, indicating complete oxidation, in lower potential. During ethanol oxidation on the catalyst PtAu, the main product formed was acetate, product of incomplete oxidation. The good performance for methanol oxidation can be attributed to large amounts of oxygen species adsorbed on the catalyst surface, or an electronic effect.
