Introduction: Primary schools are children's first social environments. Other people's attitudes towards environmental hazards play a key role in developing children's personality. This study aimed to identify and assess the environmental risks (such as emission of pollutants into the air, discharge of pollutants into water and soil, energy consumption, etc.) in Shohadaye Kork female primary sc...
background: high and intermediate energy protons are not able to form a track in a solid state nuclear track detector (ssntd) directly. however, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a ssntd. materials and methods: the protons with primary energies of 9.6 and 30 mev available at the cyclotron accelerator with corresponding lo...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
Background: Previous studies have reported the antifertility activities of sulfonamides. This study was designed to evaluate the effects of co-trimoxazole and its co-administration with folic acid on ovarian tissue in female rats.Methods: A total of 54 rats were randomly divided into 9 groups (n=6). Group I served as the control and group II (vehicle) received saline. Other groups, III to IX, r...
Airport ground lighting (AGL) systems provide visual reference to aircrafts during airport operations. In AGL systems, constant current regulators feed a beacon circuit supplied through isolation transformers. Component modeling is necessary to simulate AGL systems, and thus characterize and predict their behavior. This paper presents an isolation transformer model including transformer core sa...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Background: Spermatogenesis is a necessary process in fertility and reproductive capacity of humans. In view of the relative high prevalence of spermatogenesis disorders in men and the failure of treatments provided in conventional medicine, new therapeutic approaches are being considered. This study will be designed to investigate the effect of Ceratonia siliqua (Carob) syrup and vitamin E on ...
The “Danxia landform” is an erosional landform type originally defined in China. It is characterized by redcolored sandstones and steep cliffs, and developed via long-term erosion. Detailed quantitative geomorphometric studies of the characteristics of Danxia landforms in China have not yet been conducted. Using GIS, we conducted DEM-based geomorphometric analyses of 42 watersheds on Mt. Danxia...
Background and Purpose: There is evidence in literature that IUI is the first line treatment and the most cost-effective procedure for mild to moderate male factor sub-fertility, however, the relative influence of various semen characteristics with the likelihood of a successful outcome is controversial. This study is designed to show the correlation between semen parameters and the pregnancy...
