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 research aimed at studying the social role of reading, its importance in building knowledge and training of readers, as well as reflect on the teaching of reading in schools, with children in the literacy process. For their achievement, were used as theoretical support authors who are dedicated to the study of language, thematic reading, and phenomena that occur through it in the school environment, especially those of Bakhtin, Kleiman, Chartier, Foucambert, among others . The research was carried out using the approach of qualitative research, using participatory action research, through which the researcher could have direct contact with the observed phenomena, to participate and collect the participants' actions in its natural context, the from their perspective and their views. As for collecting and analyzing data, we used the tools of questionnaire, interview and participant observation. Its subjects a literacy class and their respective teacher, in 2009. By analyzing this information, one can draw a picture of reading in the school environment and teaching practices that surround this object. The results of the literature survey and data analysis suggest that reading is a social practice, and as such has indispensable social function in society today. And the school, one of the greatest instruments of contact with the world of letters, therefore, of reading for children means not literate, have key role in developing and training of readers who are aware of the importance of reading and perpetuate this practice in their daily lives. Similarly, subjects of research, have achieved an advanced level of literacy and understand the social role of reading and its importance to live in society, in which they belong

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

This work aims to understand the ways that have led Brazilian geographers to use the gender category as an analytic element in other to understand the production of space, through the theoretical perspective of Feminist Geographies. Thus, it is important to consider, in the history of geographical science, the theoretical and methodological foundations which enabled the inclusion of gender in researches, since this subject belongs to the field of Anthropology and Sociology and it rarely appears in geographical investigations. It is understood that the gender, as an analytical category of intertwined social relation of space, comprising not only the femininity as well as masculinity and transexualities, analyzed in a relational perspective. However , greater emphasis on the understanding of woman as an agent of space will occur, due to the importance of taking the role of women in building the world out of the hidden of history. Therefore, some works produced in Geography in Brazil will be presented and discussed in order to give visibility on the treatment of space and gender relationship

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

Over the years, water has become an increasingly valuable resource and scarce, this situation is attributed to factors such as population growth, poor distribution and increasing degradation of water resources as a result of indiscriminate human activities in the middle environment, making their dwindling availability and increasing its cost. I n this context , the use of rainwater for non-potable purposes begins to be stimulated in Brazil , as a measure to preserve this resource , while in countries such as Japan and Germany , this technique has already been used for a long time. The ability to capture rainwater reduces the demand for sanitation companies, also resulting in cost reduction with the water bill and the risk of flooding in the event of heavy rains. The stored water is used only for non-potable purposes, such as toilets, taps into the garden, for washing vehicles and clothing. This work was developed with the aim of presenting the importance of rational use of water, associated with viability constructive economic and consumption of the installation of rain water harvesting, and for that, considered four case studies. From this study, it was found that the implementation of this system has led to a reduction in costs of water and sewer consumption poses no hazard to the user and its installation does not require significant changes in building construction, however, in relation to the economy, should be made a detailed analysis in each case for investment to bring a suitable financial return within the lifetime of the system

The present study is in reference to precast concrete (panels) walls as the main structural system. The diversification of the structural systems is a reality due to specific characteristics', as a result there is a lack of study and analysis. Some systems are already established in their applications, for instance: conventional reinforced concrete, structural masonry, metal structures, and wood structure. Apart from this precast concrete elements has had a growth in building sites in Brazil, therefore professionals should be more aware. Affordable house funding initiatives to address the housing shortage has been recurrent throughout the country, additionally precast concrete walls has been an alternative that meets the three basic concepts of engineering, which are: the technique, economy, and security. The objective of this study is to gather concepts from the literature and TOMO (2012) about precast concrete walls and make a didactic synthesis of how they are viewed. The modeling structure method of the system was performed following the concept of assigning bars, using the computer program of calculations SAP2000. Initially will be presented a theoretical part, furthermore a case study to illustrate the sizing of the walls using EXCEL tables programmed with calculation routine. The results will be presented in calculated efforts by the program for further analysis. Finally, will be highlighted important items of modeling and interpretation of the results
