nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...

Today to design large hydraulic structures like dams, application of dynamic analysis in time domain seems very interesting due to its benefits. For applying such analysis, appropriate earthquake records that are compatible to site conditions are necessary for designer. Such information is rarely recorded for a dam site during an earthquake and usually the amount of recorded data is not suffici...

اهمیت سازه ها با توجه به معیارهای مختلف از جمله هزینه ساخت، کاربری سازه و ... تعیین می شود. هر چقدر هزینه ساخت بیشتر باشد باید وقت و زمان بیشتری برای محاسبات صرف گردد تا در حد امکان سازه بهینه طراحی شود. اولین سدهایی که توسط بشر ساخته شدند کاربردهای ذخیره و هدایت آب را برعهده داشتند امروزه سدها مسیولیت های حیاتی تولید نیروی برق، آبیاری، تامین آب آشامیدنی و کنترل سیلاب را برعهده دارند که اهمیت ب...

esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...

Performance based earthquake engineering approach has been under evolution for seismic safety assessment of structures. Qualitative and quantitative definition of seismic performance levels is major challenge of concrete gravity dams. The main purpose of this article is damage patterns and failure scenarios prediction of structure while they prepare a suitable basement to determine dam seismic ...
