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...
If we consider some special conditions, we can assume fundamental group of a topological space as a new topological space. In this paper, we will present a number of theorems in topological fundamental group related to semilocally simply connected property for a topological space.
The theory of twistors, developed by Penrose’,2,3) gives an alternative geometry of Minkowski space. It is therefore remarkable that the symmetry group of compactified Minkowski space, the conformal group C, is different from the symmetry group of twistor space, which is SU(2,2). The relation between these two groups is that SU(2,2) is 4: 1 homomorphic to C,, the identity-connected component of...

Organizations are moving towards a new type of work: group-to-group collaboration across distance, supported by technologies that connect rooms across distance into large collaboration spaces. In this study we report on distributed group-to-group collaboration in the domain of space mission design. We use the metaphor of the “space between” distant groups to describe the connections, interdepen...
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...
