abstract since heubners (1985) pioneering study, there have been many studies on (mis) use/ non-use of articles by l2 learners from article-less and article languages. the present study investigated how persian l2 learners of english produce and interpret english definite descriptions and demonstrative descriptions. it was assumed that definite and demonstrative descriptions share the same cen...
Zeolite-supported single-atom catalysts (SACs) have emerged as a novel class of cheap and tuneable that can exhibit high activity, selectivity stability. In this work, we conduct an extensive screening by means density functional theory calculations to determine the usefulness 3d, 4d 5d transition metal (TM) SACs-supported in MFI-type Silicalite-1 zeolite for CO2 conversion. Two reaction mechan...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...

Electromagnetic waves affect living organisms and it is of great interest for wide interaction of new sources with a diversity of frequencies and powers to life of people. In the last few years, many authors have proposed that the biological effect of electromagnetic fields in both the high-frequency and low-frequency ranges are connected with oxidative processes in tissues. Studying the change...
