Dissipadores de calor recobertos com filmes de diamante CVD foram desenvolvidos para acoplar a semicondutores, utilizando-se do Laboratório de Deposição de Filmes de Diamante CVD, na UNESP - Campus de Guaratinguetá e o Laboratório de Diamantes da Universidade São Francisco, em Itatiba, SP. Analisou-se o filme de diamante CVD sobre o silício, para emprego como dissipador de calor, porque o filme de diamante CVD pode ter o valor da condutividade térmica até cinco vezes superior ao do cobre e de dez vezes a do alumínio. Os filmes foram obtidos via deposição através de reator de filamento quente, trabalhando-se com vários filamentos retilíneos em paralelo, resultando assim em um processo que visou obter um filme mais uniforme e com grande área de deposição. Os dados para análises da composição química superficial dos filmes foram obtidos por Difração de Raios-X, Dispersão de Energia de Raios-X e para a verificação da morfologia e espessura do filme foi utilizada a Microscopia Eletrônica de Varredura. Para a verificação do comportamento da temperatura sobre o dissipador com o filme de diamante CVD foi utilizada uma câmera de imagem termográfica, marca Fluke, modelo Ti 40 FT. Foram obtidos filmes de 2 e 10 ?m sobre o silício. Estas espessuras ainda não oferecem um desempenho mecânico que o torne autosustentado. Do ponto de vista de desempenho térmico as análises mostraram que, mesmo com pequena espessura, o filme de diamante CVD apresentou bom resultado experimental. Os principais desafios de construção para esse dissipador de calor são a obtenção do filme com espessura acima de um mm e a garantia da qualidade do filme com a repetitividade do processo em cujo caso torna-se necessário definir as dimensões do dissipador antes da deposição do filme.

This work intends to investigate the biodegradation of the polymers and blend films of polypropylene (PP) and poly(hidroxybutirate-valerate) (PHBV), after UV radiation to facilitate the PP degradation, which is a polymer with long chains difficult to degrade by biological agents present in the environment. This polymer is outstanding by its mechanical properties and versatility of industrial and commercial use and the PHBV by its quick biodegradability in the environment. Blends of these materials could to present a commitment between mechanical properties and biodegradability to execute its function and after the discard to have lesser lifetime in the garbage landfills. Another aspect of this work is the controlling effect of PP on PHBV, influencing its degradation time

This work has as purpose to show what are the influences of media in the education and in the shaping the thinking and understand that ideologies are present in the films used in the classroom in kindergarten. For this, I directed the discussion beginning by concepts as Ideology and its more different definitions by several thinkers over the years, the thinkers of Critical Theory of Frankfurt School, called “frankfurtians” of first and second generation of this school, also making an association between Cinema and Education, evidencing concepts involving this association as Cultural Industry, using films properly in classrooms in kindergarten, with the teacher as mediator and then discussed what amounts of movies on children's education, how they assist and deepen the knowledge developed by students in schools of infantile education. Additionally, they are exposed the different opinions about the subject Film and Education for students from kindergarten, what benefits and what disadvantages in the use of films, the different opinions on the subject. We also discuss, in this work, the ideologies present in three films produced by Walt Disney, they are Cinderella, Snow White and the Seven Dwarfs and Alice in Wonderland, relating them to how they can contribute to the development and learning students in kindergarten. I associated more as possible the previous discussions to analyze the ideologies present in these films, by summarizing these, and decomposing them through an analysis tool called frame. Finally, I completed everything that was discussed and analyzed, which students in kindergarten may develop with the use of films in schools, what they contribute, in some way, for the learning and education of students as viewers using the school as access to different cultures and the teacher as a mediator of this relationship

Thin polymeric films deposited by plasma are very atractive for many industrial and scientific applications, in areas such as electronics, mechanics, coatings, biomaterials, among others, due to its favorable properties such as good adhesion to the substrate, high crosslinking, nanomectric thickness, homogeneity, etc. In this work, thin films were deposited by plasma immersion ion implantation and deposition technique from a hexamethyldisilazane/argon mixture at different proportions. These films were subjected to several characterizations, such as, contact angle, which presented values near to 100 degrees, surface energy, with values near to 31 mJ/m2, hardness with values between 0.7 and 2.6 GPa, thickness from 100 to 200 nm, refractive index from 1.56 to 1.64, molecular structure presenting the following functional groups in the infrared spectra region: CHx from 2960 to 2900 cm-1; Si-H around 2130 cm-1; CH3 in Si-(CH3)x around 1410 cm-1; CH3 in Si-(CH3)x in 1260 cm-1; N-H around 1180 cm-1; CH2 in Si-CH2-Si bonds around 1025 cm-1; Si-O in Si-O-Si from 1020 to 1100 cm-1; Si-N in Si-H-Si bonds around 940 cm-1; CH3 in Si-(CH3)3 in 850 cm-1; Si-C bonds in Si-(CH3)2 around 800 cm-1; and Si-H in 680 cm-1 . From these characterizations, it was possible to conclude that the concentration of argon or hexamethyldisilazane in the mixture changed the resulting polymer

Le présent travail intitulé « Réflexions sur l’enseignement de la langue portugaise aux étrangers et sur l’enseignement de la langue portugaise aux natifs », a eu pour objectif d’enquêter sur les consensus et les désacords dans l’enseignement de la langue portugaise aux differents interlocuteurs. Des lectures préalables sur des textes de difusion scientifique qui ont pour but de divulguer des expériences sur l’enseignement du portugais aux étangers ont révélé l’importance atribuée à la connaisance de la culture quand il s’agit d’enseigner une langue donnée à de tels interlocuteurs. La connaissance de la culture est très importante dans ce cas de figure car il s’agit d’une conception plus ample : celle de l’interculturalisme. C’est pourquoi, nous faisons des lectures préalables dont la méthodologie proposée pour l’enseignement de la langue portugaise aux étrangers s’organise d’une telle façon que l’interlocuteur se trouve immergé dans la culture locale. Néanmoins, quand il s’agit de réfléchir à l’enseignement de la langue portugaise dédié aux natifs et basé sur les propositions curriculaires de la langue portugaise au collège et au lycée, datés de 1993 e 1998, qui constituent des textes de vulgarisation scientifique, on peut constater la préoccupation à réfléchir sur les conceptions de langage, langue, discours, texte et grammaire, des connaissances considérées comme importantes à la proposition de methodologies de l’enseignement de la langue portugaise dans le contexte très formel de l’enseignement scolaire. Le principal objectif de ce travail a consisté à analyser l’importance de la culture dans l’enseignement de la langue portugaise aux étrangers et natifs, le rapport entre culture, language, langue, discours, texte et grammaire dans l’enseignement du portugais aux étrangers et du portugais aux natifs, ainsi qu’à identifier le poids ...
