The Elegy of cities is one kind of elegy in which a poet describes the stricken cities, pains and agonies of people of the cities undergone destruction and devastation. This research is a historical - comparative study of this genre in Persian and Arabic literature. It shows that these elegies in both Arabic and Persian Literature have the same political and internal reasons, such as the assault and the attack of the foreigners to the Islamic realms. Consequently, the Iranian and Arabic poets referred to this event as the calamity of the Muslim Ummah. They elegize about the Islamic cities regardless of geographical and linguistic boundaries. In addition, the Religious and cultural commonalities of the Arabic and Persian literary scholars lead to a one-sided point of view towards many concepts of the city elegies which is very telling of the connection between two Ummahs since the ancient times. These Persian and Arabic odes are similar in their use of sincere and honest sentiments, plain and modest diction and also because of their pervasion with wisdom, advice and religious concepts such as fatalism. These elegies are also considered as part of a historical source of the stricken cities.

Stress has determining effects on the immune response. This study was undertaken to determinethe effect of exam stress on serum IL-6, cortisol, CRP and IgE levels of medical students. Thirty five university medical students in Southern Iran were enrolled. Two blood samples were providedfrom each participant one month (first stage) and one hour (second stage) before the exam at 1.00 PM.The students completed the SpielBerger State-Trait Anxiety Inventory (STAI) questionnaire. IL-6, cortisol, CRPand IgE changes were determined in these students. The mean age of the students was 21 years. The exam stress resulted in a significant decrease in theIgE level and a significant increase in the cortisol level. The exam stress can result in a decrease in the IgE level and a significant increase in the cortisollevel. So, these changes may indicate the alterations of immunological status and presence of stress in an immunosuppressedindividual, affecting his/her health.

The purpose of this study, utilizing data envelopment analysis, is to determine the optimum capital structure about 11 industries and 314 firms which were accepted in Tehran exchange stock.This research includes two stages: first, in order to indicate the output variables of data envelopment analysis, it has dealt with the relation between financial leverage with financial and non-financial variables at different industries. The variables which have significant correlation with financial leverage have been selected as output variables. The findings signify that financial leverage, in 11 industries with profitability variable, in 6 industries with size variable and in 3 industries with fixed assets ratio has significant relations. Furthermore, except for non-metallic mineral industry, in all studied industries hierarchical theory was confirmed, while trade-off theory was merely confirmed in 5 industries.In the second stage, by using the data envelopment analysis, the optimum capital structure for any of firms was determined at different levels of industries. According to the obtained results, the studied firms can approach their optimum financial leverage and thus provide the increase of firm value and stockholder wealth.
