In this study we intent to contextualize the topic environmental vulnerability on the world stage, highlighting similarities and differences in their conceptions in Portugal and Brazil. In the literature about the vulnerability is already established the contribution of Geotechnologies, especially the Systems of Remote Sensing and Orbital Imaging as well as Geographic Information Systems (GIS) and its potential for modelling physical and socioeconomic aspects for the prevention, mitigation and facing risk manifestations, whether natural, technological or mixed. This paper aims to discuss the methodological framework of vulnerability studies and the results of application in the modelling of socioeconomic and environmental data in the context of the Region Centre of Portugal and the State of Sao Paulo, Brazil. The methodology for analysing the vulnerability of these regions was based on quantitative studies of the capacity of resistance and resilience of populations and territories. The results were consistent with the socio-environmental realities of the study areas and reflect the complexity of facing and recovery of risk situations in case of territories and populations under low economic conditions and urban infrastructure, whether in Brazil and Portugal.

O objetivo deste trabalho foi apresentar os aspectos reprodutivos de Harttia carvalhoi, Miranda Ribeiro, 1939, um pequeno loricariídeo cuja distribuição é restrita a área de drenagem do rio Paraíba do Sul. Um total de 110 exemplares de H. carvalhoi foi obtido. O período reprodutivo acontece desde setembro até fevereiro. O tipo de desova foi identificado como total e a taxa de fecundidade variou de 16 a 106 ovócitos. Este tipo de estudo é importante, visto que fecundidade é uma característica específica e é uma adaptação às condições do ciclo de vida, variando com o crescimento, densidade populacional, alimentos disponíveis e taxa de mortalidade. Também foi enfatizada a importância deste estudo, pois não há estudos prévios sobre a reprodução desta espécie

Pipelines are linear construction that intersect several environments, requiring integration of environmental and technical aspects in its various elaboration steps. Environmental impact assessment if made to integrate the environmental information to enable environmental characterization, possibility identify previously fragilities of environment what contributes to the safety forecast of the significant impacts. These studies shall consider superimpose of the elements and the worsening of critical situations that already exists. In this way, meet and analyse informations about the environmental impact assessment, constructive aspects related to pipelines transport and get environmental impact studies of the case studies, providing the student a critical vision for the discussion of the apropiate balance between description and analysis, methodological rigour and the interface between construction and the environmente with inserts. Performing the critical analysis of methodologies and applied criteria for the environmental diagnosis and impact identification, search improve the methodologies for elaboration of environmental impact studies for linear construction, particulary pipelines, minin conflicts and giving security for the license process. Await provide subsidy to direction data collection, for choosing environmental indicator and for the prognosis and indentification of impacts.

The present paper aims to analyze and problematize the manner that Brazilian gastronomy is treated in didactic books of Portuguese as Foreign Language. To reach such objective, it will be considered, specially, the approaches and the methodologies of four of those books, from distinct periods of publication: Fala Brasil (1989); Aprendendo Português do Brasil (1993); Passagens (2002); Bem-Vindo! (2009). From this analysis, it’s possible to think of new possibilities to insert the Brazilian gastronomy in a Portuguese class for foreigners, considering that the aspects of Brazil’s culture are also held inside its language; this language shows a universe beyond linguistics structure and maintains the habits and history of its people inside itself

The main objective of this project step is the evolution of scenery matter on the occidental theater media, related to space and technical possibilities of the theatrical building and space on history of contemporary arts. The main point is that scenery must communicate with a specific matter. Something in touch with the plot speeches. Something that makes all the plot elements to communicate. Acting has an specific message to deliver, and that message is what really matter to the viewer of the show. “It’s never late to state that scenery is not a decoration, or just an interior composition. Scenery is not a painting or a sculpture: it’s an integrated art form. It’s never too repetitive to say that scenery is a result from the composition with lights, shadows, shapes, lines and volumes, in balance and on harmony as a whole, that create movement and contrast” (Dias, 2001) On the second step of the project, the objective is to analyze the building process and the scenery aspects of the “Be-a-bá Brasil” show, using illustrations, pictures and analysis data of the context the show was inserted on

Os curimatídeos são espécies comuns em ambientes lênticos represados, artificialmente construídos. Estudar o ciclo reprodutivo de uma espécie é fundamental para a compreensão da biologia reprodutiva da população em seu ambiente. Por isso, o presente estudo analisou os aspectos da biologia reprodutiva dos sagüirus Cyphocharax modestus, C. cf. nagelii e Steindachnerina insculpta (Curimatidae), no reservatório da pequena central hidrelétrica Mogi Guaçu, município de Mogi Guaçu, estado de São Paulo. Os exemplares foram coletados bimensalmente entre agosto de 2005 e julho de 2006 com o auxílio de redes de emalhar (malhas 1,0 a 5,0 cm entre nós adjacentes), totalizando seis amostras. No total, foram analisados 777 exemplares, sendo 525 de C. modestus, 82 de C.cf. nagelii e 170 de S. insculpta. A dinâmica reprodutiva foi analisada considerando-se os períodos seco e chuvoso. A fecundidade foi estimada de acordo com o método volumétrico a partir da análise de 168 pares de ovários maduros, sendo 121 de C. modestus, 18 de C. cf nagelii e 29 de S. insculpta. Também foram estimadas as relações gonadossomáticas médias e as correlações do número total de ovócitos em relação ao peso e ao comprimento para cada uma das três espécies. Os resultados encontrados apontaram para desova total (sincrônica em dois grupos) para as três espécies. O número médio de ovócitos foi de 15.309 a 28.825 para C. modestus, 29.031 para C. cf. nagelii e 27.206 para S. insculpta.

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 article presents a reflection on the historical aspects and legislation on Distance Learning (DL). For this, a bibliographic and documentary research was performed with the goal of raising the necessary notes for discussion. The text begins with the characterization of the current society, the Information Society, which supports the modern distance education, which uses information and communication technologies (ICTs) to establish the process of learning teaching. Five stages of the EAD are identified. Later, the Brazilian legislation concerning the DL is punctuated, starting with the passage by Article 80 of the Guidelines and Bases Law-LBD (Law 9394/96) along with the critical analysis of Decree 5,622/05. Finally, in the final considerations is discussed the negative image that the DL carries by the Brazilian population and obstacles in the existing rules that hinder the democratization of access to education that aims DL.
