Microstructural complexity and dimensional changes in heavily irradiated zirconium

Microstructural changes of graphite irradiated with swift heavy ions

Several methods, such as electron microscopy, scanning tunnelling microscopy (STM), X-ray diffraction, and decoration technique can be used to observe radiation damage in materials. In this work, we report microstructural changes and defect clusters induced by swift heavy ions (SHI) on graphite surfaces, visualized by scanning electron microscopy (SEM). Our studies have been performed on fine-g...

Depinning frequency in a heavily neutron-irradiated MgB2 sample

The magnetic-field-induced variations of the microwave surface resistance have been investigated in a heavily neutron-irradiated MgB2 sample, in which the irradiation has caused the merging of the two gaps into a single value. The experimental results have been analyzed in the framework of the Coffey and Clem model. By fitting the experimental data, we have determined the field dependence of th...

the effect of task complexity on efl learners’ written task performance in terms of accuracy and complexity

هدف اصلی این تحقیق بررسی تاثیر افزایش میزان پیچیدگی تکالیف مکالمه محور بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 15 الی 18 سال درسطح pre-intermediate از طریق petو vhs تست به عنوان شرکت کنندگان در تحقیق انتخاب شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی دو تکلیف ساده و پیچیده را طی 2 جلسه انجام...
