at the beginning of twenty-first century, the water crisis in the priority policy andmanagement is inside and outside of the country as principle thoroughly human, social,economic and political rulers of the country is considered abundant. the world bank hasannounced that during 1960 and 2025, water resources in middle east, from 3430 m3 for theeach person in year reach to 667 m3 because of pop...

When a gas of particles is placed in a confined environment such as a room or box, the particles can bounce off the wall creating a pressure. In fact, the system can readily be very well described by the ideal gas law PV = nRT, where P is the pressure, V is the volume, and T is the temperature. This means that if one increases the temperature while holding the volume fixed, the pressure will in...

confined masonry buildings are used in rural and urban areas of iran. they performed almost satisfactoryduring past moderate earthquakes of iran. there is not a methodology in iranian seismic code (standard 2800-3rdedition) to estimate their capacities quantitatively. in line with removing this constraint, an attempt is made to studyin-plane behavior of two squared confined masonry walls with a...

     The model fluids containing hard ellipses (HEs) and Gay-Berne (GB) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using Monte Carlo simulation, NVT ensemble. The dependency of fluid pressure with respect to the wall distances is studied. The oscillatory behaviors are seen in this quantity against ...

The availability of clean water in the Kuber Beach tourist area is not known for certain. To determine depth and characteristics aquifer, rock resistivity measurement was carried out using geoelectric method with Schlumberger configuration on two tracks a span 200 m each. results showed that semi-confined aquifer at below 8 from ground surface. Aquifers sand lithology have low potential, while ...

Characteristics of space analogue environments with regard to human performance concern the crew adaptation in a socio-psychological context and in a temporal dynamics. Isolation, confinement and time are major features on Earth to reproduce an extra-terrestrial environment for manned mission simulations. In the current space missions (low Earth orbit, LEO) and in the perspective of interplanet...
