introduction: biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. the results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...
Transition metal dichalcogenide (TMDC) materials are very important inelectronic and optical integrated circuits and their growth is of great importance in thisfield. In this paper we present growth and fabrication of MoS2 (Molibdan DiSulfide)thin films by chemical bath method (CBD). The CBD method of growth makes itpossible to simply grow large area scale of the thin la...
The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...
the present study aimed at exploring cognitions of iranian english teachers within the context of english for academic purposes (eap). to this end, the cognitions of two groups of eap teachers with respect to their pedagogical content knowledge (pck) and their sense of professional identity (pi) were probed. two language teachers and two content instructors who had at least five years of eap te...

abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
One of the most efficient methods to reduce emissions and fuel costs of SI engines in petrol case, is the use of combined gasoline and NG. The ability of an engine is usually expressed with maximum power and maximum torque output of full-load state, but the operating time of the engines with full-load is less than that of part-load time. Therefore, studying the performance of the engine with a ...
