In order to study the genetic diversity of 75 Iranian rice genotypes (45 Iranian land race, 25 improved cultivars, and 5 exotic cultivars) with respect to their salinity tolerance at seedling stage and to determine tolerance indices, based on biomass, genotypic code and Na+/K+ ratio a factorial experiment in randomized complete block design with three replications was conducted under control an...

We find the greatest values $alpha_{1} $ and $alpha_{2} $, and the least values $beta_{1} $ and $beta_{2} $ such that the inequalities $alpha_{1} C(a,b)+(1-alpha_{1} )H(a,b)
برنامه ریزی فضایی عبارتست از، نحوه توزیع و سازمان یابی انسان و فعالیت ها در پهنه سرزمین. در اصل برنامه فضایی، برنامه ریزی ساختار کالبدی و فعالیتی سطح مورد برنامه ریزی است.نخستین کار در فرآیند برنامه ریزی در سطوح کلان،تعیین مناطقی به عنوان واحدهای همگن برنامه ریزی می باشد.از این رو هدف این پژوهش تعیین مناطق همگن برنامه ریزی در سطح استان تهران با تأکید بر نظام برنامه ریزی شهری و روستایی در این من...
تحلیل رخساره های لرزه ای بدون نظارت به منظور برآورد کردن خصوصیات مخزن با استفاده از ترکیب نشانگرهای لرزه ای در الگوریتم های شناسایی الگو، یکی از روش های بسیار مهم تفسیری است. بدون توجه به توانمندی روش به کاررفته در تحلیل رخساره های لرزه ای، دسته بندی داده ها در درون مخزن باید با دقت کامل صورت گیرد. با توجه به پیچیدگی های موجود در سامانة مخزن، سطح اطمینان از یک تفسیر، با توجه به دقت داده های لرز...
background: it is becoming apparent that although inhibition of cholinesterase plays a key role in organophosphate (op) toxicity, other factors are also important. one of the contributing factors for severity of op poisoning is electrolyte imbalances such as hypokalemia. this study was aimed at evaluating the value of hypokalemia in association with plasma cholinesterase (pche) levels in predic...
in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...
many commonly used statistical methods require that the population distribution be nearly normal. unfortunately, in some papers the one-sample kolmogorov-smirnov test has been used for testing normality while the assumptions of applying this test are not satisfied. to conduct this test, it is assumed that the population distribution is fully specified. in practical situation where the mean and ...
Background: Chang in the serum K+ level may increase perioperative morbidity and mortality in kidney transplant recipients. Thus this research was done with the aim of evaluated of K+ change in kidney transplant recipients. Hence the following study was carried to evaluate the fluctuation of potassium ion in the kidney transplant recipient patients. Materials and Methods: In a simple randomized...
introduction: this study was carried out to compare the capability of k-files with mtwo rotary file in terms of negotiation as well as depth of penetration in second mesiobuccal (mb2) canal of maxillary first molar. materials and methods: a total of 32 mb2 canal of maxillary first molars having different root curvatures (not more than 30 degree) and root lengths were selected and then detected ...
