from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...

Emotion regulation strategies are considered as determinant variables on both normal and psychopathological processes. The aim of the present study was to investigate the mediating role of emotion regulation difficulties on the relationship between social anxiety symptoms and anger. A total of 171 participants (71 men, 100 women) from the city of Tehran participated in this study as volunteers....

This study explored the effects of GnRH agonist (GnRHa) immunity on expression of FSHR mRNA in pituitary and FSHR protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (EG) during anestrus season. Animals in EG-I, EG-II and EG-III were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

A high efficiency frequency doubler is realized based on a single embedded gate (EG) graphene field effect transistor (GFET) with natural Al oxidation dielectrics. Due to elimination of the step of depositing gate dielectrics, the fabrication process of the EG-GFET is improved compared to conventional EG-GFETs. The capacitive efficiency of the EG-GFET is improved up to 80 times compared to the ...

electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...
