Formate drilling and completion fluid system is a new type of clean organic salt brine system which has been developed from inorganic salt brine drilling fluid system. It is beneficial to protecte and find hydrocarbon reservoir. Due to the solid free system, the damage of solid phase particles on reservoir, especially low permeability oil and gas layer, can be greatly eliminated, at the same ti...

Acid phosphatase is wildly found in plants. This enzyme has intra and extra cellular activity. For instance, it dephosphorylase organic phosphate and change it to inorganic phosphate. However, acid phosphatase activity is increased by salt and osmotic stress. In this experiments, calluses were produced from invitro grown explants of Medicago sativa cv. Yazdi and cv. Hamedani under aseptic condi...

Abstract In recent years, nanoparticles have emerged as an important player in a broad range of applications, especially thanks to advances their synthesis. The silver and copper are often used due antibacterial fungicidal activities, this article presents the results nanoparticle synthesis using electrical glow discharge generated directly volume salt solutions. Therefore, there is no influenc...
