This article first studies the process of the formation of the art of emulation by examining its development and evolution in both Arabic and Persian literature. Then the article would compare and contrast the emulated poetry in Arabic and Persian. The hypothesis is that Persian emulation, like many other poetic forms, comes from Arabic literature. Thus the fundamental question is “How to examine the nature and quality of the similar and common features and issues of Persian and Arabic emulation?”. Thus the literal and literary senses of emulation are first studied, and then its representative examples in Arabic and Persian poetry and prose are listed. In this section, such subjects as echo, parody, burlesque, takhmis, and tadhmin are relevant examples that are introduced as the common devices in both literary traditions. In the manner of a conclusion, an analytical treatment of these writings is conducted, taking into consideration their positive and negative implications and effects.

Backgrounds: Coronavirus disease 2019 (COVID-19) pandemic is considered as a global health challenge, and Iran is among the top ten countries with the highest mortality rate. This study aimed to analyze epidemiological, clinical, and laboratory features of hospitalized SARS-CoV-2 infected patients and identify the risk factors of mortality among them to facilitate the prioritization of resources and vaccine allocation in the population using data available in a large university hospital in Tehran, Iran.
Materials & Methods: From February 20 to May 14, 2020, a total of 684 COVID-19 confirmed cases were admitted to Imam Hossein University hospital in Tehran and enrolled in this retrospective observational study.
Findings: The mean age of the participants was 59.48±16.65 years, and 55.8% were male. Compared to survivors, non-survivors (n=127, 18.57%) were older (69.09±14.16 vs. 57.29±16.40), had higher average number of comorbidities, and more frequently suffered from dyspnea, convulsion, loss of consciousness (LOC), tachycardia, tachypnea, and hypoxia. They also had higher levels of leukocytes, neutrophil count, C-reactive protein (CRP), creatine phosphokinase (CPK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), international normalized ratio (INR), prothrombin time (PT), partial thromboplastin time (PTT), urea, and serum creatinine (p<.05). Serum potassium (K), lymphocyte count, hemoglobin, HCO3, and serum sodium (Na) were significantly lower in non-survivors. Multivariable logistic regression analysis results revealed that nine variables were positively associated with mortality.
Conclusion: Among COVID-19 patients admitted to the hospital, having more than two or three comorbidities, loss of consciousness, SpO2 < 90%, increased CRP, CPK, urea, and serum potassium, were associated with mortality.

Linguistic studies under the influence of second wave of feminism, has been introduced scientifically in linguistic field. Lakoff, a famous linguist, believes that different socialization and power sharing between men and women leads to difference in their language. After representation of this theory,many linguists start to investigate in this context and following these investigations they found different language variables in language of men and women. Some of these variables are standard and informal language, imperative speaking commands, moderators, curse words and so on. These variables are significant in works of fiction. The aim of this article is to study female language characteristics in “Kanizo” a novel by MoniroRavanipor based on sociolinguistics and considering suggested variables by Lakoff and other linguists. The result of studies showed that women’ language in Ravanipor’s novel is not weak in contrast with the belief of linguists. In spite of the fact that these women are weak and oppressed by men, there is a significant difference between their language and men’s and this weakness is separate from what linguists introduced as weakness.
