O segundo satlite da Misso Espacial Completa Brasileira (SCD2/MECB) foi colocado em rbita em 23 de Outubro de 1998 e carrega a bordo um experimento de clulas solares. Clula solar de silcio um dispositivo semicondutor, que pode medir a intensidade da radiao visvel e parte da radiao infravermelha (400-1100 nm). O experimento permite medir simultaneamente a insolao direta e parte da radiao solar que refletida pela Terra para o espao. Os dados do experimento clula solar so transmitidos em tempo real pela telemetria do satlite e recebidos pela estao terrestre em Cuiab, MT-Brasil (16S; 56W). Este fato limita a cobertura espacial para um crculo sobre a Amrica do Sul. O albedo planetrio obtido dentro desta cobertura e seus valores podem ser agrupados em perodos temporais (anual, sazonal ou mensal), ou podem ser estudados para vrias localizaes (latitude e longitude) durante a vida do satlite. O coeficiente de transmisso atmosfrica ou ndice de claridade (Kt), medido em estaes meteorolgicas na superfcie da Terra, junto com o valor medido simultaneamente do albedo planetrio, permite calcular o coeficiente de absoro atmosfrica (Ka). O mtodo desenvolvido neste trabalho para avaliar Ka considera que o albedo planetrio composto por duas partes: uma refletividade local e uma refletividade no local. Considerando este novo conceito, definida uma taxa de absoro atmosfrica (denominada Ra) que a razo entre Ka e a potncia de irradincia solar lquida, que no atravessou a atmosfera (100%-Kt). A taxa de absoro atmosfrica assim definida independente da cobertura de nuvens. O histograma de freqncia de Ra mostra os valores de 0,860,07 e 0,880,09 sobre as cidades de Botucatu-SP e do Rio de Janeiro-RJ, durante os anos de 1999 at 2006, respectivamente.

Different forms of human pressure may occur in the pipeline ranges, due to the large extensions and various configurations of land use, which can pass through the pipelines. Due to the dynamics of these pressures, it is necessary to monitor temporal changes of land use and cover the surface. Under this theme, appears as extremely important to use products and techniques of remote sensing, as they allow the identification of objects of the land surface that may compromise the security and monitoring of the pipeline, and allows the extraction of information conditions on land use at different periods of time. Based on the above, this paper aims to examine in a temporal approach, the process of urban expansion in the municipality of Duque de Caxias, located on the outskirts of the metropolitan area of the state of Rio de Janeiro, as well as settlement patterns characteristic of areas that the changes occurred in the period 1987 to 2010. We used the technique of visual analysis to perform the change detection and the technique of image classification, aimed at monitoring human pressure over a stretch of track pipeline Rio de Janeiro - Belo Horizonte, located in the state of Rio de Janeiro. The stages of work involved the characterization of the study area, urban sprawl and the existing settlement patterns, through the analysis of bibliographic data. The processing of Landsat 5 images and the application of the technique of change detection were performed in three scenes for the years 1987, 1998 and 2010, while the classification process was performed on the image RapidEye for the year 2010. Can be noted an increase in urban area of approximately 22.38% and the change of land cover from natural to built. This growth is concentrated outside to the area of direct influence of the duct, occurring in the area of indirect influence of the enterprise. Regarding the settlement patterns of growth areas, it was observed that these are predominantly

The analysis of natural processes, such as landslides, has a great importance for the prevention of accidents in pipelines, since it might compromise its security, with serious social and environmental implications. Considering the large territorial dimensions that pipelines can reach, remote sensing tools have great applicability for data acquisition, allowing the analysis of large areas in regular time periods. This study aims to analyze the relations between the occurrence of landslides and its natural conditionings, on a stretch of the ORBEL pipeline, in the municipalities of Duque de Caxias, Nova Iguau and Belford Roxo Rio de Janeiro. GeoEye sensor system images were used with spatial resolution of 0.5 m, from November/2009, January/2010 and March/2010, that are months of summer rains. The work involved the characterization of the study area and existing landslides, through bibliographic data collection; the application of visual analysis techniques for the extraction of landslide scars and fractures; preparation of maps for the landslide constraints and preparation of the susceptibility map. In the images from November only three landslide scars were extracted, while in January there were 166 and 111 in March. Difficulties were found with the shading in the images. From the relations among landslide scars, lithological units, relief systems, slope, downhill profile and the generated map of landslide susceptibility, presented in 1:70,000 scale, it was possible to conclude that slope is the main determinant of the process, allied secondarily to downhill profile, relief systems and lithology

There will be a review on the collaboration of Ea de Queirs in Gazeta de Notcias (Rio de Janeiro-1880-1897), written directly to the Brazilian public. In some of these texts Ea makes reflections on the mediation that the newspaper plays in society, particularly in southern Europe. We believe that in these texts there are manifestations and traits of doctrinal-programmatic nature, metalitterary aspects and also a kind of history of occidental press. These press texts are now gathered in Textos de Imprensa IV da Gazeta de Notcias, which includes the volume critical edition of the works of Ea de Queirs, coordinated by Carlos Reis. The study of these texts will contribute to the analysis and interpretation of his fiction and journalistic works.

O estudo do momento inicial na constituio deste patrimnio cultural, de sua histria e das disputas que gerou, inclusive na memria, realizado a partir da noo de coerncia ilusria de uma gerao de etnlogos, militares e intelectuais e da ao do Estado nacional brasileiro na dcada de 1950.
