14. Um estudo comparativo da eficiÃncia das usinas hidrelÃtricas do Brasil, utilizando a anÃlise por envoltÃria de dados â DEA / A comparative study of the efficiency of the brazilian hydroelectric units, using the Data Envelopment Analysis â DEA.
The recent structural modifications that occurred in the electric brazilian sector had, in its essence, as main purpose to guarantee a reliable energy supply. But, how to guarantee the energy supply without sufficient financial resources to invest in the construction of new electric generation plants, necessary to supply of the energy front to the expansion

15. Landscape transformation due to the building of Funil hydroelectric power station â UHE-Funil and the impact of its building on the town of Ijaci, MG / TransformaÃÃes na paisagem decorrentes da construÃÃo da usina hidrelÃtrica do Funil UHE- Funil e o impacto no municÃpio de Ijaci, MG
The building of a hydroelectric power station causes transformations in the regional landscape, in a process contrary to the long-standing movement of its formation, with negative impacts to both the fauna and flora. The establishment is defined by pre-requirements as water availability, topography and geological factors, without an integral landscape study

16. Os usos da água para geração de energia elétrica e a sustentabilidade jurídico-ambiental. / Water uses for a generation of eletrical energy and the environmental law sustainable.
In order to achieve the doctorate degree, our study aims to provide guidelines for judicial reading with the purpose of preventing ecological and social impacts in the exploitations of hydroelectric potentials. The work has as its core two management instruments: granting of rights of use of water resources and environmental license. Three ventures have form

17. Planejamento regional / territorial : a interface entre os planos diretores de aproveitamentos hidrelÃtricos e os planos diretores municipais
This research allowed to understand the way the Managing Plan of Hydroelectric Plants affects the organization of the territory. The use and occupation of the surrounding of the reservoirs of major hydroelectric enterprises have shown irregularities caused by the inappropiate use of these areas for tourism and recreation. Therefore, this work ananlyses the M

19. 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

20. Identificação de impactos e conflitos ambientais em bacias hidrográficas de interesse energético : projeto-piloto na bacia do Rio do Sono - TO
Este estudo é uma contribuição para a identificação de impactos e conflitos ambientais em bacias hidrográficas de interesse energético. Analisa as diferenças conceituais entre impacto e conflito ambiental, bem como, discute a necessidade de maior diálogo entre os diferentes setores usuários de água, especialmente no que tange à apropriação dos

21. Methodology of prospection and evaluation of pre-viability fast of ditributed generation (DG): eolic and hydraulic case. / Metodologia de prospecção e avaliação de pré-viabilidade expedita de geração distribuída (GD): caso eólico e hidraúlico.
Estudos convencionais de identificacao e de viabilidade de potenciais de producao de energia eletrica eolica e hidroeletrica de pequena escala demandam trabalhos de campo que, muitas vezes, implicam na inviabilidade economica do negocio em funcao dos seus onerosos custos. Alem disso, a execucao desses trabalhos nao assegura ao investidor a recuperacao desses

22. Planejamento regional / territorial : a interface entre os planos diretores de aproveitamentos hidrelétricos e os planos diretores municipais
Esta pesquisa possibilitou compreender a forma como os Planos Diretores de Usinas Hidrelétricas afetam a organização territorial. Os grandes empreendimentos hidrelétricos apresentam irregularidades no uso e ocupação do entorno de seus lagos, pois, entre suas conseqüências, além da produção energértica, percebe-se a utilização dessas novas paisa

23. Cerrado assemblages of reptiles and amphibians along the drainage of Rio Tocantins and the impact of hydroelectric power plants on their conservation / Assembléias de répteis e anfíbios do Cerrado ao longo da bacia do rio Tocantins e o impacto do aproveitamento hidrelétrico da região na sua conservação
The Cerrado herpetofauna was studied along the basin of the Tocantins river using three distinct and complementary approaches. First, a fast sampling scheme, covering all the studied area, was conducted in 11 sites between the Central Plateau, in the state of Goiás, and the northern portion of the Tocantins depression, at the border of the states of Tocanti
