خریداران عموماً در مورد کالاها براساس ویژگیهای بیرونی (extrinsic cues) آنها قضاوت می کنند ، به ویژه هنگامیکه سنجش ویژگیهای ذاتی کالا مشکل باشد. به همین علت است که کشـور سـازنده کـالـا، (country of origin or coo) ، یکی از این ویژگیهای بیرونی محصول ، عموماً برای ارزیابی کالاهای خارجی مورد استفاده قرار میگیرد. اثرات کشور سازنده کالا در حوزه رفتار خرید مصرف کننده (consumer buying behavior)بطور گسترده...
هدف از انجام این تحقیق ارزیابی اثر تکرارهای مکرر hcg بر روی ویژگیهای جسم زرد و فولیکولهای موجود بر سطح تخمدان و غلظت پروژسترون میش های سنجابی سوپراووله شده با ecg می باشد. تعداد 40 راس میش سنجابی بوسیله اسفنج آغشته به پروژسترون به مدت 12 روز جهت همزمان سازی فحلی مورد درمان قرار گرفتند . سوپراوولاسیون در این دامها بوسیله ecg، 2روز قبل از خروج اسفنج القاء شد. در روز خروج اسفنج (روز صفر) میش ها بص...

We report 30-nm-gate-length InAlN/AlN/GaN/SiC high-electron-mobility transistors (HEMTs) with a record current gain cutoff frequency (fT ) of 370 GHz. The HEMT without back barrier exhibits an extrinsic transconductance (gm.ext) of 650 mS/mm and an on/off current ratio of 10 owing to the incorporation of dielectric-free passivation and regrown ohmic contacts with a contact resistance of 0.16 Ω ...
The propagation of the fundamental quasi-symmetric Lamb mode S(0) travelling along 3C-SiC/c-AlN composite plates is theoretically studied with respect to the AlN and SiC film thickness, the acoustic wave propagation direction and the electrical boundary conditions. The temperature effects on the phase velocity have been considered for four AlN/SiC-based electroacoustic coupling configurations, ...
Twenty-two aromatic derivatives bearing a chlorine atom and a different chain in the para or meta position were prepared and evaluated for their in vitro antifungal activity against the phytopathogenic fungi Botrytis cinerea and Colletotrichum gloeosporioides. The results showed that maximum inhibition of the growth of these fungi was exhibited for enantiomers S and R of 1-(4'-chlorophenyl)-2-p...
The lattice structure of the AlN/SiC interface has been studied in cross section by high-resolution transmission-electron microscopy. Lattice images show planar and crystallographically abrupt interfaces. The atomic arrangement at the plane of the interface is analyzed based on the image characteristics. Possible bonding configurations are discussed. Variations in local image contrast and inter...

in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
Stock portfolio optimization is always an interesting and attractive research problem due to the variety of stock markets. To find a useful portfolio, metaheuristic-based approaches have been presented obtain diverse group portfolios (DGSPs) by considering diversity in past. However, existing DGSP algorithms, two problems remain be solved. The first how set suitable size, second that evolution ...
