abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
the present study is paid to the evaluation of the welfare program of the unemployment insurance in iran. the main purpose which was the main reason for performing this thesis, was the unemployment insurance plan’s challenges in iran such as financial problems of this plan, prolongation of the credit receipt for some insured people, unemployment slow exiting from the unemployment insurance fund...
Put the peroxodisulfate ion (S2O82-) in the phase transfer catalyst banzyltriphenylphosphonium can make a catalyst with mild oxidation property, and used it for oxidation of Benzylhalides to corresponding Benzylaldehyde Compounds. For making catalyst used xylene and water as solvent, and it was an easy process with high yield. Oxidation used in reflux condition with acetonitrile as solvent. The...

Capability indices measure the performance of a process. Although process yield is the primary focus on the performance criteria, the " ( , ) p C u v indices combine process yield and process centering. With this compromise, there is no direct link between the process yield and these indices, but literature provides lower and upper bounds for the process yield. However errors in the proposed re...
Carbon nanotube field effect transistors (CNTFETs) have been considered as one of the potential candidates for nanoelectronics beyond Si CMOS. However, it is not easy to have high performance CNTFETs with high yield currently. In this work, we proposed a local bottom-gate (LBG) CNTFETs combined with a novel device concept and optimized process technologies. High performance of CNTFET with low s...
