1. Characterization and Metal Detoxification Potential of Moderately Thermophilic Bacillus cereus from Geothermal Springs of Himalaya
Two thermophilic Bacillus cereus strains (B. cereus-TA2 and B. cereus-TA4) used in the present study were isolated from the geothermal spring of Hunza valley, Gilgit, Pakistan. They showed the ability to withstand and grow at high temperature (85°C). Both these strains could resist multiple metals (copper, cadmium, mercury, manganese, zinc, arsenic, chromiu

2. Avaliação do potencial geotérmico da bacia sedimentar de Taubaté / Evaluation of Taubate basin geothermal
Os recursos conhecidos de energia geotermal no Brasil são de baixa entalpia, com fontes contendo fluidos com valores de temperatura inferiores a 100ºC. Isto por si só desencoraja a tentativa de buscar cenários possíveis de aproveitamento das fontes, restritas até então, aos usos através de balneários, com o aproveitamento dos poços mais profundos p

3. The genetic diversity of genus Bacillus and the related genera revealed by 16S rRNA gene sequences and ardra analyses isolated from geothermal regions of turkey
Previously isolated 115 endospore-forming bacilli were basically grouped according to their temperature requirements for growth: the thermophiles (74%), the facultative thermophiles (14%) and the mesophiles (12%). These isolates were taken into 16S rRNA gene sequence analyses, and they were clustered among the 7 genera: Anoxybacillus, Aeribacillus, Bacillus,

4. APROVEITAMENTO DE FONTES ALTERNATIVAS PARA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA E REFLEXOS NOS SEUS CUSTOS / UTILIZATION OF ALTERNATIVE SOURCES FOR REDUCING POWER CONSUMPTION AND ITS CONSEQUENCES IN COSTS
Residential consumption accounts for around one third of total energy consumed in Brazil. The electric shower is the main component of this consumption, along with air conditioning. Hence, much research has been conducted in order to reduce the consumption of this sector and the use of alternative energy sources. Among these include mainly solar and geotherm

5. MATRIZ ENERGÉTICA BRASILEIRA: IMPACTOS AMBIENTAIS E À SAÚDE
The Brazilian energy matrix is directly responsible for economic development, technology and science in the country. The diversity of the energy matrix of a country decreases the risk of energy crisis, since it does not depend on a single energy source, but a further another. Given this importance, this work aims to analyze the MEB and its impacts on the env

6. Geology of the Camboriú Complex (SC) / Geologia do Complexo Camboriú (SC)
The anatectic origin evidenced by known macrostructures in migmatites of the Camboriú Complex is supported by petrographical, geochemical and isotopic data, with partial melting under compressional regimen being suggested by the large amount of leucosome bodies at low-pressure sites represented by interboudins and dilation surfaces. Despite the continental

7. Geothermal gradient and heat flow in the state of Rio de Janeiro
Resultados de estudos geotérmicos efetuados em 72 localidades foram utilizados na avaliação de gradientes de temperatura e o fluxo geotérmico da crosta superior no Estado do Rio de Janeiro. As investigações incluíram a realização de perfilagens térmicas em furos e poços, determinação dos gradientes térmicos, medições de condutividades térmic

8. High temperature corrosion issues in energy-related systems
The large majority of electric power that is generated world-wide involves heat engines of one kind or another. The significant exceptions are hydroelectric generation; wind; and photovoltaics. The thermal sources for the heat engines include: fossil fuels, nuclear fission, biomass, geothermal sources, and solar radiation. There has been a progressive move t

9. ContribuiÃÃo Ãs tÃcnicas de locaÃÃo de poÃos em terrenos de rochas cristalinas no semi-Ãrido brasileiro
Geological and geophysical studies were accomplished in the areas of Carnaubeira da Penha and Alagoinha in the semi-arid region of Pernambuco where Neo and Mesoproterozoic crystalline rocks occur. The study aimed at a better understanding of the variables upon which well yields are dependent in hard rock territories, in order to improve well site selection t

10. Ensaios não convencionais para determinação da tenacidade à fratura em rochas: análise e comparação / Non-conventional tests for determining the fracture toughness in rocks: analysis and comparison
Since early 1970 s new fracture mechanics concepts have been developed to explain rock fracture behavior. Fracture toughness has been measured and considered as an important intrinsic property of rock indicating the magnitude of fracture strength or its ability to resist crack propagation. Rock fracture mechanics has been widely applied to tectonics, energy

12. Phylogenetic Diversity Analysis of Subterranean Hot Springs in Iceland
Geothermal energy has been harnessed and used for domestic heating in Iceland. In wells that are typically drilled to a depth of 1,500 to 2,000 m, the temperature of the source water is 50 to 130°C. The bottoms of the boreholes can therefore be regarded as subterranean hot springs and provide a unique opportunity to study the subterranean biosphere. Large v
