1. Space Propulsion: a Survey Study About Current and Future Technologies
ABSTRACT: Current Space Launch Vehicles use chemical reactions (solid and liquid propellants) to achieve sufficient thrust to launch artifacts and humans into space. Propulsion technologies can be framed in three different categories: "escape propulsion", "in-space propulsion", and "deep space propulsion". The launch vehicles currently used for "escape propu

2. Brazilian Science and Technology Policy and the Case of Embrapa Semiarid
Abstract This study focuses on Brazil’s international co-operation in science and technology (S&T), notably technical transfers to the semiarid branch of the Brazilian Agricultural Research Corporation (Embrapa) from the early 1990s onwards. It is based on interviews with Embrapa personnel, as well as literature and documentary reviews. It starts by outli

3. Delimitation of kala-azar risk areas in the district of Vaishali in Bihar (India) using a geo-environmental approach
Remote sensing and geographical information technologies were used to discriminate areas of high and low risk for contracting kala-azar or visceral leishmaniasis. Satellite data were digitally processed to generate maps of land cover and spectral indices, such as the normalised difference vegetation index and wetness index. To map estimated vector abundance

6. GEOMDQL: Uma Linguagem de Consulta geogrÃfica e Multidimensional
There have been a number of proposals in the literature aimed at integrating functionality and characteristics related to analytical (OLAP - Online Analytical Processing) and geographic (GIS- Geographic Information Systems) data processing. The main goal is to provide a unique environment with geographicmultidimensional processing capabilities in order to pr

7. The use of geo-technologies to evaluate the potentiality of hydro-degradation in superficial waters by agro-chemicals : case of Antas River watershed, Bueno Brandão, MG / Utilização de geotecnologias para a avaliação do potencial de degradação hidrica das aguas superficiais por agroquimicos : caso da sub-bacia do Rio das Antas, Bueno Brandão, MG
In the county of Bueno Brandão, South of MG, the Antas River Watershed is located before the water supply area and is susceptible to hydro-degradation due to the damaging agricultural activities-chemicals was evaluated by the use of geotechnologies. The potato cropping is a remarkable activity among them due to the following features: intensive use of agro-

8. DEVELOPMENT OF AN INTERFACE IN SIG FOR SUPPORT TO THE HYDRAULICAL SIZING OF SYSTEMS OF WATER SUPPLY / Desenvolvimento de uma Interface em SIG para Suporte ao Dimensionamento Hidráulico de Sistemas de Abastecimento de Água
The studies in water resources are models that need data gotten in the maps or research of field. Recently, these information are being added directly in Geographic Information System (GIS) due to the technological advances developed by these systems and to the continuous improvements in digital land model. Currently, efforts have been carried through to dev

9. Uma Infra-estrutura para IntegraÃÃo de Modelos, Esquemas e ServiÃos Multidimensionais e GeogrÃficos / An Infra-structure for Integrating Multidimensional and Geographical Models, Schemas and Services
Decision support is a field of Information Technology that aims to help in understanding the behaviour of the business data of an organisation. Data Warehouse (DW), On-Line Analytical Processing (OLAP) and Geographical Information System (GIS) are tools for providing decisionmaking support. While DW and OLAP are technologies for performing multidimensional p
