An experiment was conducted to address the relationship between the types of cereal grain and ascites syndrome in broiler chickens raised in a high-altitude region. A number of 252 one-day-old broiler chicks (Cobb 500 strain) were randomly assigned to three dietary treatments including a corn-soybean diet (corn diet), a wheat-soybean diet (wheat diet), and a barley-soybean diet (barley diet). Chicks were kept on experimental diets for 42 days, during which growth performance and carcass traits were assessed, and blood samples collected. Results indicated that corn substitution with wheat and barley significantly suppressed feed intake, growth rate, and lipogenesis as reflected in lower serum cholesterol, triacylglycerols, and abdominal fat deposition (P = 0.0001). Feeding barley resulted in down-regulation of TLR2 and GLUT2 genes but caused an up-regulation of FABP2 gene in jejunum as compared to the corn control. Feeding wheat and barley did not significantly affect the relative weights of the heart, and the right to total ventricular weight ratio (RV/TV). Mortality from ascites was not significant among treatment groups. In conclusion, substituting corn for wheat or barley could impair broiler performance, but under the conditions of this experiment had no significant impact on susceptibility to ascites.

"Al-Mizan Fi Tafsir Al-Quran" is one of the interpretive works of the contemporary period, which is on a higher level than its counterparts both in terms of method and approach. One of the characteristics of this interpretation is the social dimension of Al-Mizan. The rethinking and searching for the intellectual and spiritual needs of the people of the community in the light of the Qur'an is one of the prominent and clear lines of Al-Mizan's interpretation. The political and social changes that took place in the nineteenth and twentieth centuries and the questions that were expected from religion in this regard and the culture that resulted from the influence of Western civilization on Muslim society are among the most important social developments in the Islamic world. This is an attempt to examine the social and political issues that Allameh Tabatabai raises in the interpretation of Al-Mizan following the political and social developments of the society. Allameh Tabatabai in Al-Mizan is an approach based on the two parts of denying and proving the presentation. have given. In the stage of negation, it puts different ideas and schools on the scales of criticism, and in the stage of proving Islamic ideas, it sets out the principles of Islam in laying the foundations of the Muslim community from the perspective of the Qur'an.

Desert ecosystems have substantial economic potentials that paying attention to them to attain sustainable development and to get rid of the one-product economy is essential. According to the growing demand for ecotourism, calculating the recreational value of recreational areas seems to be necessary for efficient and effective management. The purpose of this study is to determine the factors affecting the willingness of tourists to pay in the Qaleh-Bala area of Biarjamand city in Semnan province. To examine the factors affecting the willingness to pay, the Logit model was estimated by the maximum likelihood method. To measure the willingness to pay off the Qaleh-Bala Double-bounded Dichotomous Choice, it was used. The required data were prepared and collected by completing a questionnaire and face-to-face interviews with visitors from the area. The tourist samples were selected by a simple random sampling method for 207 people, and then the questionnaires were completed by them. The results of the Logit model showed that the coefficients of the variables number of visits, final destination, and distance from residence, monthly household expenses, and offered price were significant at the level of 1% and 5%. Finally, the average willingness to pay for the use of the area by visitors was 48,220 Rials and the annual recreation value of Qaleh-Bala village was estimated at 434 million Rials

Non-Revenue Water(NRW) is one of the most important problems that beneficiaries companies are trying to reduce. Most of researches have been done in this subject, focused on actual losses and leakage in water conveyance and distribution systems and less attention has been paid to the second component of NRW and Precision of Measurement Equipment (PME) yet. In this research, due to the lack of a clear scientific knowledge about the replacement of Water Meters(WM) in national water and wastewater engineering companies, field studies have been carried out on the PME and errors of subscribers' WM and the performance range of the WMs was compared using a new approach. At first, the identification of effective parameters on the accuracy of the WM was investigated and then by clustering method, the WM were compared and the effect of each parameter on the accuracy of the WM was determined. In order to predicting the performance and accuracy of the WM, Artificial Neural Network(ANN) algorithm was used and for optimizing the weights and biases matrix, Genetic Algorithm(GA) was used too

3 jurisprudential rules The authority of men over women is based on verse 34 of Surah An-Nisa ', which is the source of many rules and regulations in jurisprudence and law, especially in family law and male-female relations. Male domination over women in our system, in cases such as the wife's obedience to her husband; Determining the location; The right of a man to oppose a woman's job; Citizenship; Husband's guardianship has affected children and many other cases. There have been different and sometimes conflicting interpretations of this verse. Some commentators in the interpretation of the verse "By the grace of God, some of them are Ali" some have mentioned more than ten cases in proving the superiority of men over women: Alimony and household expenses, and finally the divine decree. Some believe; The best interpretation of the above verse, according to the context of the verses before and after and even the beginning and the end of the verse, is related to the relations between men and women in the family. Others, by generalizing causes such as rational powers, have extended the ruling of the verse to society and believe in the guardianship of men over women. . However, there is strong scientific evidence that strongly denies the biological difference between men and women in sexual matters; But assuming the acceptance of the theory that in the real world, in the nature of human beings,

Because the performance assessment of the health system is used as the basis for decision‑making and demonstrates progress or failure in achieving the goals of the health system, promoting the health system performance assessment can play a major role in improving and enhancing the health system. Therefore, the main aim of the study was to identify and prioritize the challenges of promoting the health system performance assessment.

There were two approaches in both qualitative and cross‑sectional studies. At first, using semi‑structured interviews with 52 performance appraisers, data related to the challenges of promoting the health system performance assessment were collected and thematically analyzed. Then, in cross‑sectional terms, the performance appraisers were provided with researcher‑made checklists which contained a list of challenges to determine the priority of challenges by scoring. The data were handled and analyzed using MAXQDA Plus version 12 and Microsoft Excel.

Our results revealed five themes and ten subthemes on the challenges of promoting the health system performance assessment. Themes (subthemes) included infrastructures (cultural and technological), implementation (organizational support, process, and responsibilities), human resources (motivation and training), assessment (performance monitoring), and content of measures (reliability and validity). We also prioritized 31 listed challenges in three priority groups, including below average, average, and above average.

Our findings suggest that promoting the health system performance assessment in Iran can be accomplished by allocating financial and nonfinancial motives to the performance assessment staffs, using performance assessment results in policymaking, clarifying tasks of assessment process executors, and reviewing and adapting the performance assessment indices according to contingencies in the health system.
