The regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. The conductivity titration and UV spectroscopy were used to study the interaction of iodine with these catalysts. The results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...
This paper tries to study the role of political leadership and how it influenced victories and failures during history. Therefore, in a journey through fluctuating Iranian history, four prominent and influential wars of past two centuries – initially Iran-Russia war and finally Iran-Iraq war- have been studied. While comparing Iran's political leadership in these wars and their consequences, th...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...

The lugworm Arenicola marina is one of the most successful species on intertidal mudflats and is highly adaptable to various abiotic stress factors in its changeable environment. This applies not only to oxygen partial pressure and salinity, but also to temperature, which varies greatly around the annual mean of 10°C in the North Sea. Thus, intertidal lugworm populations of the Wadden Sea can b...
the effect of sublingual nitroglycerine (tng) on relieving pain in renal and ureteral colic was studied in a randomized, prospective, double blind and placebo controlled clinical trial. one hundred out-patients between 16-60 years of age from either sex who were admitted to the urology emergency center of ayatollah taleghani and ashrafi esfahani hospitals were chosen for this study. they were d...
