Thermal springs commonly occur along faults because of the enhanced vertical permeability afforded by fracture zones. Field and laboratory studies of fault zone materials document substantial heterogeneities in fracture permeabilities. Modeling and field studies of springs suggest that spatial variations in permeability strongly influence spring locations, discharge rates and temperatures. The ...

This study was carried out primarily to understand the hydrogeochemical processes controlling 226Ra anomalies in Ramsar area. Analyses revealed two types of water: (1) non-thermal Ca–HCO3 type and (2) thermal Na–Cl type, mainly meteoric hydrothermal origin, respectively. Non-thermal springs have higher concentrations U due silicate weathering. Thermal are characterized by high 226Ra, As, Fe, Li...

The PCM based energy storage system is commonly used for storing waste heat and solar heat. Main disadvantage of such system is slow response during charging and discharging. In the present experiment thermal conductivity of wax based storage system is improved by embedding Copper,Aluminium and iron springs. Experiments shows that such systems show superior performance during charging and disch...

Acidic thermal springs offer ideal environments for studying processes underlying extremophile microbial diversity. We used a carefully designed comparative analysis of acidic thermal springs in Yellowstone National Park to determine how abiotic factors (chemistry and temperature) shape acidophile microbial communities. Small-subunit rRNA gene sequences were PCR amplified, cloned, and sequenced...

Two important facts have drawn the attention of medical men to radio-activity. The first fact was the observation that radium rays affect the tissues of the human bod}\ For ljke Ronto-enrays they are able to cause serious injuries to&the skin. The first man who tried to utilise radium rays for medical purposes was Dr. Danlas of the St. Louis Hospital in Paris, who used them successfully to cure...

The arrangement of the centers of the molecules in the crystal is that corresponding to the diamond structure. Each molecule is surrounded tetrahedrally by four molecules. If we consider a molecule as roughly tetrahedral in shape with similar orientation to the tetrahedron formed by the four beryllium atoms, then the adjacent molecules are so oriented as to present tetrahedral faces to one anot...

since nox family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. in the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (ntps) have an oxidative potential, which results in an effective conversion of no to no2. ...
