Iran has faced with water scarcity problem for a long time. There is a strong tendency to desalinate seawater from Oman or the Caspian Sea as intake seawater and transfer it to central parts of the country. These projects face significant technical, economic, and environmental challenges. In this work, utilizing available economic theories about single-stage reverse osmosis (RO) desalination plants, the cost analysis of a conceptual plant with a production capacity of 200,000 m3/day, was accomplished assuming the use of Oman and Caspian seawater as feed. The effect of important parameters such as applied pressure, recovery ratio, total salt content of the feed, and produced water and the temperature has been studied theoretically. The results show that under the same working conditions, the final product price per cubic meter of freshwater from the Caspian Sea is $ 0.69 versus $ 1.24 for the Oman Sea, which is about 50% cheaper. The lower salinity of the Caspian Sea compared to the Oman Sea is the main reason, which lead to reduce in the capital cost of the RO membrane (62% difference), cost of the intake and pretreatment (20%), and cost of membrane elements replacement (13%) regardless of water transfer cost.

Abstract: Feminism literally means "women's liberation"," womanism " which is itself divided into different ways. Feminism has sometimes been interpreted as organized movements for women's rights and sometimes for the theory that believes in equality between men and women in political, economic, social and legal terms. With the spread of the feminist movement, much work was written on women, and all of them had a fixed principle that was to remove the inferiority and inequalities that had been permitted to women throughout history. With the spread of such works, feminist literature emerged. And many poets and writers have created works in this regard. Kuwaiti poet Souad al-Sabah is one of these poets. In this study, we have tried to look at feminism and its implications in terms of feminism, including patriarchy, patriarchy, women's dependency, women's subordination, and lack of public presence in Souad al-Sabah 's poetry.

To develop and validate “Treatment Satisfaction with Traditional Medicines” Questionnaire (TSTMQ), a preliminary 22-item instrument was designed. Content validity ratio (CVR), content validity index (CVI), Intra-class correlation (ICC), and Cronbach alpha were measured, and exploratory and confirmatory factor analysis (EFA and CFA) were conducted. Data were analyzed using SPSS (17) and LISREL softwares (8.8). Finally, TSTMQ with 14 items and in three domains were confirmed after measuring CVR (> 0.62), CVI (> 0.79) and EFA. ICC for the entire questionnaire was 0.99 (95% CI: 0.95-0.99) (P<0.001), and Cronbach alpha was also 0.87. In CFA, all factor loadings and t-values were greater than 0.3 and 1.96, respectively. Also, χ2/df, RMSE and GFI were 2.6, 0.062, and 0.94, respectively. This study showed that the TSTMQ is a standard tool to measure treatment satisfaction with traditional medicine.
