attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
privatization advocates believe that transfer to private sector increases firm’s performance and value, business environment, and therefore economic growth and welfare improves. in this research, by using the 70 accepted firms in the tehran stock exchange for the period of 2005 to 2009, we investigate the effect of firm’s ownership structure on their value by applying generalized method of mome...
در این پایان نامه داده¬های لرزه¬ای دقیق ناحیه زاگرس در بازه زمانی 2006 تا 2013 میلادی با بزرگی مساوی و بیش از 2 ریشتر از پایگاه اینترنتی مرکز لرزه¬نگاری کشور دریافت شده و بر اساس این داده ها، آهنگ¬ لرزه خیزی در ناحیه زاگرس مورد بررسی و مطالعه قرار گرفته است. کمربند چین¬خورده-رانده زاگرس یکی از لرزه¬خیزترین نواحی ایران بوده و زمین لرزه¬های آن ناشی از همگرایی بین دو صفحه ایران و عربی می¬باشد. تغی...

The theoretical framework of research is the social system theory based on Talcot Parson's action theory.UN adopted range of 15-24 was used to select the youth, then by Cochran sample size, 266 young people and 532 individuals(father and mother)were selected. Questionnai...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
