the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...

The acoustic wave velocity depends on elasticity and density at most materials, but because of anisotropy and especially piezoelectric coupling effect, the acoustic wave propagation at piezoelectric based crystalloacoustic materials, is an applied and challenging problem. In this paper, using modified Christoffel's equation based on group velocity concept, the effect of anisotropy and piezoelec...

Introduction: Studies have shown that brain waves are anomalously active in anxiety patients, but so far, no interventional studies have been performed. Therefore, the purpose of the present study was to determine the effectiveness of cognitive rehabilitation on reducing anxiety and brain wave pattern in patients with anxiety. Anxiety disorder was widespread. Methods: This study was quasi-expe...
