This paper tries, across research, books, magazines and charts that relate to the architecture of today, establishing a direction as to the technological advances that may be involved in the architecture project. Such that the configuration space has flexibility to meet the basic architectural principles and the wishes of the user, who should participate as a key character of the decisions of spatialization - interface. Both the personal point of view of their social relations within the housing, and the functional environments equipped and qualified to meet expectations during its use. Respecting the power of free choice of human beings, not to put yourself to the detriment by excessive use of technology. And still look for ways to integrate the individual to society connected to your network - home. Keywords: interface, information, technology, space flexibility

The purpose of this work is to study the incorporation of hydrogen production (Case A) and the process of gasification of sugarcane bagasse associated with combined cycle gas turbine and steam turbine (Case B) for Distillery Pioneers process. These technologies can be used to improve the energy supply in the sugarcane mill. Initially the processes for obtaining sugar and ethanol from sugarcane is discussed, with a theoretical introduction to hydrogen, the process of steam reforming and gasification of biomass (bagasse) by inserting a turbine associated with the recovery boiler gas. Subsequently makes up the energy and exergy analysis of the incorporation of the above technologies. In end stage makes it an ecological analysis considering or not the carbon cycle (photosynthesis), to determine the levels of emissions of pollutants, carbon dioxide equivalent, indicators of pollution and ecological efficiencies associated with technological developments proposed. It is concluded that hydrogen production by steam reforming of ethanol and gasification of bagasse are viable alternatives from the point of view of technical and environmental applications in the biofuels industry, contributing to the development of the sector in the country

This work studies the incorporation of new technologies in the sugarcane sector. Are considered the ethanol steam reforming and the gasification of sugarcane bagasse(by-product) processes associated with combined cycle systems (Gas Turbine + Steam Turbine), aggregating hydrogen production and increased electricity supply in the sector, respectively. To verify the technical feasibility of the incorporation processes was performed a thermodynamic analysis, considering data from a typical Brazilian Sugar Cane Industry. In another step the economic viability study of the hydrogen production process was made, with consideration on hydrated and anhydrous ethanol steam reform, comparing the cost of hydrogen production. Also considered studies of economic engineering of the gasification process and the generation of electricity associated. As conclusions, it follows that the ethanol steam reforming is a great alternative for hydrogen production, presenting production cost relatively low, especially when is considered the steam reforming of hydrated ethanol. For the gasification process associated with combined cycle, can be observed an increase of 8.56 times of the electricity production in the sugar cane industry, indicating a positive annual saving when the sales price of the supply electricity is greater than 0.070 US$/kWh. Finally it can be concluded that the incorporation of these new processes allow greater profitability and operational flexibility of Brazilian sugarcane mills

The process of steel production emits a large quantity of greenhouse gases, specifically carbon dioxide (CO2), and the reduction of such emissions is one of the main challenges for the industry in the 21st. Century. To quantify these emissions, the Worldsteel Association (association of the 170 large steel manufacturers of the world) published a methodology (CO2 Emission Data Collection) for calculation and comparison of CO2 emissions among its members. After that, in 2010, this methodology became an ISO (International Organization for Standardization) norm. Today, the calculation of the CO2 emissions in steel making companies follow the ISO 14404-1 for units with blast furnaces and the ISO 14404-2 for units with electric furnaces. In the last years, new technologies were and continue to be developed for the steel making sector aiming at energetic improvements and greenhouse gas reductions (mainly CO2) by the several processes involved in the production of steel. This work had the objective of producing a tool to calculate the CO2 emissions for the steel making sector. An Excel spreadsheet was developed to calculate the emission intensities of CO2 of a steel plant, the Usina Presidente Vargas, of the Companhia Siderúrgica Nacional (CSN). The spreadsheet furnishes results of CO2 emissions and energetic fluxes, and simulates the benefits that some of the new technologies can give to the company. The spreadsheet calculates the emissions in two ways: a) based on the carbon fluxes that enter the unit, and b) based on the emissions of each specific process within the unit (coking, sinterization, blast furnace, among others)

This study investigated, by descriptive documental research, the intervention models in Sexual Education in the school with the participation of the family and use of new technologies. The methodological stages were: collects in bases of data, selection and reading of the studies and elaboration of thematic groupings, by the content analysis. Four thematic group were elaborated: 1) intervention models with professionals; 2) intervention models with adolescents; 3) intervention models with the direct participation of the family and 4) Appreciation of the family’s participation in sexual education. The analised articles prioritize the adolescent population, when descrive the intervention. Few studies consider the family as important to sexual education and the techniques of the computer science are not very explored as pedagogic resources.

Apesar da importância do atletismo, ainda são vários os problemas enfrentados por aqueles que se dedicam a ensiná-lo. Procurando estratégias que contribuam para sanar algumas dessas dificuldades, essa pesquisa teve como objetivo identificar as Novas Tecnologias de Informação e Comunicação (NTIC), em especial, a internet, como forma de subsidiar o ensino do atletismo em aulas de Educação Física. Para atingirmos o objetivo proposto, nos pautamos no desenvolvimento de quatro etapas, a saber: 1ª Etapa - pesquisa bibliográfica, em livros, artigos e websites, visando coletar materiais didáticos relacionados ao atletismo; 2ª Etapa - análise e divisão dos conteúdos da internet, em especial, dos vídeos do Youtube, por possuírem diversos conteúdos relacionados ao atletismo; 3ª Etapa - organização do banco de dados, no formato de material didático, com base nos vídeos do Youtube, capaz de subsidiar o trabalho do professor de Educação Física na escola, com sugestões de atividades a fim de tornar as aulas sobre atletismo mais dinâmicas e numa linguagem cada vez mais frequente no dia a dia dos alunos

Sustainability suggests a new social organization required for human survival. The aggravation of environmental problems arising by population growth, industrialization, disorderly and unconscious consumption of Human Being, induces us to think about how to stop these problems. Recycling presents itself as a means of stopping environmental destruction and as a way to increase the family income of the poorest society existing in our globalized world. This article suggests a research on recycling being carried out as a means of livelihood.
