In order to identify the effects of different levels of nitrogen fertilizer on seed yield and seed growth indices of some bread and durum wheat genotypes, a field experiment was conducted in 2013-2014 in Khuzestan Agricultural and Natural Resource Research Center. The experiment was designed as a split plot with three replications. Nitrogen application rates (50, 100 and 150 kg N.ha-1) were ass...
this research was investigated to analyze genotype × environment (ge) interaction for grain yield in durum wheat multi-environment trials (met) conducted in dryland agricultural research stations (dari) using gge (g + ge interaction) biplot methodology and joint regression analysis (b + s2di). the environment, ge interaction and genotype effects were accounted for 84%, 7.7% and 2.3% of total s...
background: avian infectious bronchitis (ib), with avianinfectious bronchitis virus (ibv) as the causing agent, is a ubiquitous endemicdisease of the chicken with devastating effects on its industry. a viralmembrane surface protein called s notonly induces neutralizing antibodies but also plays an important role in virusbinding and entry to host cells. technically, s1 protein gene sequencing a...
This study was conducted to estimate stability of yield in forage sorghum varieties for identifying varieties with combine stability and high yield potential across two cropping conditions. Thus, seven forage sorghum varieties were evaluated for three years under two cropping conditions including spring (E1) and summer (E2) cropping, using a randomized complete block design with four replicatio...
Background and purpose: Statins are among the most widely used drugs in treatment of cardiovascular diseases. Reducing the side effects of these drugs is of great importance in preventing treatment failure. The aim of this study was to investigate the role of rs4149056 polymorphism in statin-induced myopathy in patients with cardiovascular diseases in West of Mazandaran province, Iran. Materia...
results genotype b (73.6%) and genotype c (26.4%) were detected in these patients. after treatment for 12 months, the rate of hbv dna seroclearance, alt normalization, and hbeag seroconversion were significantly higher in adv group than in placebo group (p < 0.05). however, there were no significant differences in these three rates between patients infected with genotype b and c (p > 0.05). obj...
the following null hypothesis was proposed: there is no significant difference between the efl students listening comprehension development receiving pictorial cues and those receiving no cuse. to test the null hypothesis, 52 male and femal freshmen students of medicine studing at iran university of medical scinces were randomly selected from a total population of 72 students. to ensure that th...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
اغلب تحقیقات انجام شده در حوزه ی " یادگیری مشارکتی " نشان ازتاثیرات مثبت آن بر موفقیت تحصیلی ، افزایش دانش و توانش زبانی، انگیزه ، تعاملات میان دانش آموزان(مهارتهای گروهی و پذیرش افراد با سطح درسی ضعیفتردر گروه)، و هم چنین علاقه به محیط آموزشی دارد .البته لازم به ذکر است که تحقیقاتی هم حاکی از عدم تاثیر این نوع یادگیری وجود دارد. بر اساس این پیشینه ، پژوهش حاضر به بررسی تاثیر "مدل یادگیری با هم...
In order to evaluate the effect of deficit irrigation treatment and foliar application of ascorbic acid and jasmonic acid on morphophysiological traits of safflower genotypes (Carthamus tinctorius L.), the experiment was set out in a split plot factorial in a randomized complete block design with three replications at Shahrekord University Agricultural Research Station during the two years, i.e...
