drought is still limited in most crops is produced. morphological and physiological knowledge to improve drought resistance under drought conditions created problems important is the fact each of these genetic relationships and processes associated with the exact amount of important plant and grain yield is unknown. the other hand, heritability of grain yield under water is reduced. improve the...

background: rapid advancement of information and communication technologies has transformed the methods of education. it has created methods which help students achieve deep and effective learning as well as develop a desirable level of creativity. implementation of e-learning in education is one of such methods. the purpose of the present research is to study the impact of self-learning (self-...

the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...
