2. 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.

3. Richness and structure of ant assemblies (Hymenoptera: Formicidae) in Atlantic forest in southern Brazil
ABSTRACT Ant diversity is influenced by the structural complexity of the environment. Ants are thus an ecologically important group due to their potential to serve as indicators of environmental quality. The objective of this study was to evaluate ant diversity in areas with different land use histories and thus, within different stages of regeneration in th

4. Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia
ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks o

5. Phlebotominae sand flies (Diptera: Psychodidae): potential vectors of American cutaneous leishmaniasis agents in the area associated with the Santo Antônio Hydroelectric System in Western Amazonian Brazil
INTRODUCTION: An entomological study was conducted as part of a vector-monitoring program in the area associated with the Santo Antônio hydroelectric system in State of Rondônia, Western Amazonian Brazil. METHODS: Fourteen sampling sites were surveyed to obtain data on the potential vectors of Leishmania spp. in the area. Sand flies were collected from 20

6. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

7. Geração distribuída aplicada à edificações : edifícios de energia zero e o caso do laboratório de ensino da FEC-Unicamp / Distributed generation applied to buildings : net zero energy buildings and the case of the laboratory at FEC-Unicamp
Electricity consumption in Brazil increased 47% in the last decade, and it is estimated that it will increase 55.6% until 2020. Most of the electricity generated in the country is based on large hydroelectric dams, located away from the major cities. The planned expansion of the generation park to meet this increase in the demand is also based on this model,

8. Regionalização de potencial hidrelétrico com escassez de dados : aplicação Moçambique
Hydroelectricity (hydropower) is one branch of water resources engineering, which uses water (river flows) producing electricity. A hydroelectric undertaking, besides providing electricity and its comfort, it also allows the establishment of other productive activities, which provides a good economic and social development of the population (social responsab

9. APROVEITAMENTO DE ENERGIA VERTIDA TURBINÁVEL PARA PRODUÇÃO DE HUDROGÊNIO E GERAÇÃO DISTRIBUÍDA / USE OF THE WASTED HYDROELECTRIC POTENTIAL FOR HYDROGEN GENERATION AND DISTRIBUTED ENERGY
Em muitas Usinas Hidrelétricas, quando as afluências de água são maiores que a demanda, uma parcela desta água que ainda poderia ser utilizada para gerar energia é desviada para o vertedouro e literalmente desperdiçada. Esta energia recebe a denominação de Energia Vertida Turbinável (EVT). Essa dissertação discute o aproveitamento da EVT para pro

10. Downstream passage of fish larvae and eggs through a small-sized reservoir, Mucuri river, Brazil
In South America, one important symptom of the failure of fish passages to sustain fish migratory recruitment is the inability of eggs and larvae to reach the nurseries. This is especially so when the breeding areas are located upstream of a reservoir, and the floodplain is downstream of the dam. Therefore, the transport of fish larvae and eggs across reserv

11. Modelo computacional de cortes para otimizar o potencial de geração de usinas hidrelétricas / Computacional model of cuts to optimize the potential to generate hydro power plants
The repowering of hydro power plants increases their generating capacity by improving the structure or changing equipment. It is a low cost alternative to improve the generation capacity comparing with the building of new plants. Repowering by changing the hydro-turbines is the focus of this work. By doing that, the efficiency of the energy generation proces

12. ANÁLISE ESTRUTURAL DE PÁS DE GERADOR EÓLICO DE PEQUENO PORTE FEITAS DE FIBRA VEGETAL BRASILEIRA / STRUCTURAL ANALYSIS OF BLADES SMALL WIND GENERATOR MADE OF BRAZILIAN VEGETABLE FIBER
The wind energy potential in the Northeast of Brazil, and especially in the state of Ceará is huge and offers conditions to compensate the missing options for building further full size hydroelectric Power plants and to guarantee the energy supply for this region with green renewable energy. Apart from that it offers opportunities for promoting a sustainabl
