Moreover lowering the level of Lake Nasser in order to limit the evaporable loss would concomitantly reduce the hydroelectric power, but in return, Egypt would receive additional water for irrigation.
Therefore, the electrical resistance of concrete will be mainly controlled by the types and concentration of ions of evaporable water in the capillary pores of the cement paste.
In this study, vacuum evaporation from the molten state was implemented by original low-vacuum coater, which is feasible for coating a wide range of organic materials that are evaporable under low-vacuum conditions.
Selection of solvents was based on some characteristic factors; for example, the solvent should be easily evaporable, and density should be less than that of plant material so that extracting solvent should penetrate the plant material completely yielding greater recoveries of target analyte artemisinin.
