Dye pollution is a serious threat to aquatic environment and human health. Although activated carbon an efficient adsorbent for dye reclamation from effluents, its expressive nature renders use on large commercial scales. On the other hand, waste biomasses are not effectively used any beneficial purposes. Sawdust biomass of wood mills, due small particle sizes, it has potential be as adsorbent....

architecture has been always recognized as a framework which is influenced by social beliefs, traditions and interactions and furthermore affects individual soul and tendency. therefore it is impossible to analyze and consequently identify an architectural artifact if not accompanied by analysis of intellectual fundamentals of its contemporary society. the ensemble of sheikh safi al-din which i...

Passive phase-change thermal spreaders such as vapor chambers have been widely employed to spread the heat from small-scale high-flux heat sources to larger areas. In the present work, a numerical model for ultra-thin vapor chambers has been developed which is suitable for reliable predictions of the operation at high heat fluxes and small scales. The effects of boiling in the wick structure on...

Drying of solid particles is generally divided into three periods: a short initial heating period, a constant drying rate period, and a falling drying rate period. Drying in a fixed under various drying conditions was experimentally studied. The main goals of the measurements were to calculate the heat transfer coefficient based on the measured values, and to evaluate the validity of the consta...

– We present results of all-electron electronic structure calculations for the recently discovered d electron heavy fermion compound LiV2O4. The augmented spherical wave calculations are based on density functional theory within the local density approximation. The electronic properties near the Fermi energy originate almost exclusively from V 3d t2g states, which fall into two equally occupied...

at early period of ghobad’s reign, sassanid king (486-531ad), an important movement occurred, headed by mazdak, for several social, economic and political reasons so that the king supported it in order to weaken the position of great figures and clergymen as well. naturally, important people opposed the given movement and dethroned ghobad king from power and he managed to resume his reign again...
