1. Analysis of solar photovoltaic energy potential in Brazilian hydroelectric reservoirs through floating panels
Abstract Sustainability, a concept used to exploit natural resources without harming future generations, is being applied to power generation. In Brazil, the main source of electric energy comes from hydroelectric plants, due to abundant water resources. However, the implementation of these plants causes irreversible impacts on the environment and society.

2. An assessment of the factors determining rotifer assemblage in river-lake systems: the effects of seasonality and habitat
ABSTRACT Zooplankton exhibit several trends of variation in space and time, and these trends can be more evident in natural environments without anthropic perturbations. Examples of anthropic factors are climate change, eutrophication and construction of reservoirs. This study evaluated the influence of three factors - seasonality, type of environment and th

3. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

4. Um método multiobjetivo para o posicionamento de barragens / A multiobjective method for placement of dams
Este trabalho apresenta um método para determinar, aproximadamente, a posição mais apropriada em um terreno representado por um modelo digital de elevação para construir uma barragem tal que o reservatório gerado possa armazenar um dado volume de água. A posição será selecionada considerando os pontos do rio e será feita baseando no custo de const

5. Impacto da RecuperaÃÃo dos Investimentos na Infraestrutura HÃdrica (Barragens e Adutoras) sobre a CobranÃa pelo Uso da Ãgua. / Impact of the recovery of investment in water infrastructure (dams and water pipelines) on charging for water use.
The works of water infrastructure often clash over the issue of lack of financial resources for the construction and operation. It then becomes the hypothesis of obtaining the funds for water infrastructure construction by charging for the raw water. Then, comes up the question: what is the impact on water charges if the cost of water infrastructure construc

6. Influência das frentes frias nos mecanismos de funcionamento da represa da UHE Carlos Botelho (Lobo/Broa) Itirapina SP, dos pontos de vista químico, físico e biológico
In Brazil there is a numerical predominance of river systems, which favors the construction of reservoirs. These reservoirs have great ecological, economic and social significance, so, the management, conservation and recovery of these systems are of fundamental importance with repercussions on the economy, social work and the uses of aquatic systems.

7. LIQUID-LIQUID DISPLACEMENT FLOWS IN A HELE-SHAW CELL INCLUDING NON-NEWTONIAN EFFECTS / DESLOCAMENTO DE LÍQUIDOS EM CÉLULA DE HELE-SHAW CONSIDERANDO EFEITOS NÃO NEWTONIANOS
This work studied the displacement of fluids in porous media using a Hele-Shaw cell. Specifically, was investigated experimentally the displacement of a non-Newtonian fluid by a Newtonian in a rectangular Hele-Shaw cell. The Saffman-Taylor or viscous fingering instability occurs when one fluid pushes a more viscous one, and a Hele-Shaw is a convenient tool t

8. Aplicação de microemulsões na solubilização de frações pesadas de petróleo
This work presents studies related to the use of microemulsions in the solubilization of heavy crude oil fractions responsible by the formation of deposits. The first stage of the work was addressed to the construction of phases diagrams, with the intention of determining the area within which the microemulsion is formed. The following systems were studied:

9. LEISHMANIOSE TEGUMENTAR AMERICANA: uma abordagem farmacológica
The leishmaniasis (ACL) is a zoonotic disease whose etiologic agent, species of the genus Leishmania. And a disease of the skin and mucous membranes, primarily zoonotic involving a variety of wild and domestic mammals. Outbreaks of leishmaniasis occur by environmental changes due to deforestation, construction of dams, roads, mines, plant work areas, militar

10. AVALIAÇÃO AMBIENTAL DA OCUPAÇÃO ESPACIAL DO VALE DO RIO TOCANTINS POR USINAS HIDRELÉTRICAS
In Brazil, due to its enormous quantity of rivers, most part of the electric energy available comes from large hydroelectric power plants. The construction of these hydroelectric enterprises involve a series of social-environmental changes on the site of location but are essential to supply the energy demand of the Country. The necessity of mitigation of the

11. Caracterização geométrica e parametrização de depósitos transacionais recentes e sua aplicação na modelagem de reservatórios petrolíferos
In this beginning of the XXI century, the Geology moves for new ways that demand a capacity to work with different information and new tools. It is within this context that the analog characterization has important in the prediction and understanding the lateral changes in the geometry and facies distribution. In the present work was developed a methodology

12. Estudo da fauna de mosquitos (Diptera: Culicidae) em reservatórios de contenção de cheias em área metropolina da cidade de São Paulo, SP / Study of mosquitoes fauna (Diptera: Culicidae) in the reservoirs for the contention of food waters in São Paulo city metropolitan area, SP
Introduction. The City of São Paulo has been adopting highly measures to enable it to face up to the problem of flooding, among them being the construction of Reservoirs for the Containment of Flood Waters, known as "piscinões". In the dry season, after the occasional rains, these reservoirs, especially their hydraulic machinery, serve as breeding places f
