plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
همزمانی فحلی یک روش مدیریتی ارزشمند است که برای افزایش کارایی تولید مثل به خصوص در گاو، گوسفند و بز به صورت موفقی استفاده می شود. همزمانی فحلی در نشخوارکنندگان کوچک، هم با کاهش طول فاز لوتئال فحلی با استفاده از PGF2α و هم با افزایش طول آن با استفاده از پروژسترون اگزوژن انجام می گیرد. در این مطالعه اثر دوزهای مختلف گنادوتروپین کوریونی اسب (eCG) با استفاده از پروژسترون داخل واژنی (CIDR) بر روی هم...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
background : during the last 3 decades, there were increasing tendency towards angioplasty because of its benefits. but, this procedure has its acute problems like bleeding and formation of hematoma in the removal place of the sheet. based on researchers’ clinical experiences, patients need a time of 8-12 hours for bed rest after coronary angioplasty. recognizing desirable time for bed rest aft...
The objective was to determine the effects of exogenous prostaglandin F(2α) (PGF), with or without progesterone treatment, on first ovulation in prepubertal heifers. We tested the hypothesis that PGF has a luteolysis-independent ovulatory effect in cattle. Crossbred Angus heifers (12 to 14 mo old, 250 kg body weight, and an average body condition score of 3 out of 5) were examined by transrecta...
Two experiments evaluated long-term progestin-based estrus-synchronization programs on the basis of potential for use in facilitating fixed-time AI in estrous cycling and prepubertal beef heifers. In Exp. 1, heifers were assigned to 1 of 2 treatments by age, BW, and estrous cyclicity status. Heifers assigned to the melengestrol acetate-PGF(2α) protocol (MGA-PG; n = 50) received MGA (0.5 mg·anim...
it seems that the presence of soil organic matter (som) increases p availability to plants. this effect has commonly been ascribed as competition between the decomposition products of som and p for soil sorption sites resulting in p concentrations increase of soil solution. this study was carried out to obtain information about soil organic matter (som) influence on kinetics and thermodynamics ...
