16. Contra as invasões barbaras, a humanidade : a luta dos Arara (Karo) e dos Gavião (Ikoloehj) contra os projetos hidreletricos do Rio Machado, em Rondonia / Against the barbarian invasions, humanity : Arara (Karo) and Gavião (Ikoloehj) indigenous people agaist hydroelectric projects of Machado s River, in Rondonia, Brazil
The dissertation deals with the struggle of Arara (Karo) and the Gavião (Ikólóéhj) indigenous people against hydroelectric projects of Machado s River, in Rondônia, Brazil. This mobilization was initiated in the 80 s against the project of Usina Ji-Paraná, suspended in 1993, and remains until the present day, with the resumption of the project of Usina

17. Evaluation of the hydraulic potential in hydrographic basins by using the geographical information systems / Avaliação do potencial hidráulico em bacias hidrográficas por meio de Sistemas de Informações Geográficas
The hydroelectric resources in the Country, either in terms of the capacity already installed and its potential still unexplored rather represent greatly strategic and economically important assets. In generation of the decentralized electric power, the hydroelectric minicentrals (MCHs) are distinguished within an environmental management and preservation co

18. Reação álcali-agregado nas usinas hidrelétricas do Complexo Paulo Afonso/CHESF: influência da reação nas propriedades do concreto. / Alkali-aggregate reaction at the Paulo Afonso Hydreletric Complex/CHESF: influence of the reaction in the properties of the concrete.
Several are the concrete deterioration processes and the alkali-aggregate reaction (AAR) is classified as a chemical deterioration process. As a reaction result and in an umid environment expansion products are formed, being able to cause cracking, loss of strength, increase of deformation, loss of functionality, reduction of the durability of the structure,
