in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
مقدمه : استعمال سیگار و مواد مخدر از جمله معضلات رایج بهداشتی محسوب می شوند. نه تنها استعمال سیگار، بلکه مواجه با دود آنها نیز عواقب زیادی را برای انسان ایجاد می نماید. در معرض دود سیگار بودن نیز خطر ابتلا به سرطان و بیماری های قلبی و عروقی را افزایش می دهد. یکی از عوامل مطرح شده در مورد مصرف سیگار اختلال در روند التیام زخم می باشد. بر همین اساس بر آن شدیم که به بررسی اثر مصرف سیگار بر روی باز ...
The Roman imperial monarchy is generally studied from the vantage point of ancient Roman history: the “Roman emperor” is viewed and analyzed as an element of the Roman world. This conventional approach fails to place this institution in a broader comparative context, that of monarchical rulers across world history. Systematic comparison opens up new perspectives and is indispensable in identify...
The antiquities of Jammu and Kashmir reveal that women might have enjoyed a high status as elsewhere in India. But ,there was a marked deterioration in the position of women. Female children were not much desired and their sufferings became endless with the beginning of inroads of Turko-Afghan tribes for whom carrying away of women formed the prized item of booty. This situation gave new dimens...
The impact of the Mongol invasions of the Middle East has been the subject of extensive research, especially in the last few decades. Scholars have evaluated the damage and the benefits brought by the Mongols to the Islamic world in different fields such as the military, religion, politics, economy and culture. Despite this, in the case of Anatolia, the Mongol period is still under-studied when...
Islamic Art is the art of civilization based on Islamic religion. Moreover, it not only concerned with particular region or particular people rather it is a combination of different civilizations and historical circumstances as painted with Islamic weltanschauung. The Arab civilization is probably more important. Although the Arabs have little art and even then, they developed Islamic art with ...
Studies of headache risk factors are numerous but their results are based on clinics and hospitals. Few data have been reported in children. No data are available regarding migraine and tension-type headache risk factors among Iranianchildren. Therefore we determined the sociodemographic risk factors of migraine and tension-type headaches and their correlations in schoo...
he main objective of the advertising discourse is to encourage its viewer or reader to buy goods. this dialogue contains several inductive functions, including inductive functions of action and tension. the function of the induced action is an action-induced origin, whereas the function of the inductive tension is induced by the action originated. thus, tension-induced functions can be claimed ...
We consider mappings between edge sets of graphs that lift tensions to tensions. Such mappings are called tension-continuous mappings (shortly mappings). Existence of a mapping induces a (quasi)order on the class of graphs, which seems to be an essential extension of the homomorphism order (studied extensively, see [10]). In this paper we study the relationship of the homomorphism and orders. W...
