در این پایان نامه سعی شده است جدیدترین و بهترین مدلهای محاسباتی خزش ارائه شود. سپس مدل خزش خاک نرم که مدل محاسباتی نرم افزار laxis می باشد به طور کامل تشریح شده و در پایان نامه برای بررسی خزش از این مدل که یکی از بهترین و دقیق ترین مدلهای محاسباتی خزش می باشد استفاده شده است.
due to cereal are affected by drought stress in their lifetime. in order to study gene action of bread wheat under drought stress condition, a generation mean analysis was performed using f1, f2 and f3 generations derived from roushan and kavir. generation mean analysis was performed based on joint scaling test. genetic parameters including additive effect (d), dominance effect (h), additive×ad...
in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...
in this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. geometry of sheet strip is pre-estimated by a shape function. then longitudinal, transversal and shear strains have been calculated. using both the levy-mises and the prandtl reuss equations, and also considering the bauschinger effect, stress distributions have b...
In order to evaluate the effect of water stress on sunflower cultivars of Iroflor in different stages of growth and methods of biophosphate consumption, a factorial experiment was conducted in a randomized complete block design with four replications. Water deficit stress in four levels including control (non-stress), stress in vegetative stage, stress in reproduction stage and stress in both v...

the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
To evaluate the effect of copper nanoparticles on the characteristics of mallow under drought stress conditions, a factorial experiment was conducted in a completely randomized design with three replications under greenhouse conditions in 2017. The first factor of drought stress was at three levels without stress and 75 and 50% of field capacity and the second factor was copper nanoparticles at...
salicylic acid (sa) is part of a signaling pathway that is induced by a number of biotic and abiotic stresses. it has been recognized as an endogenous regulatory signal in plants. in order to study the effect of different concentrations of sa on germination, growth and some physiological parameters in chickpea (cicer arietinum l.) two genotypes (mcc414, mcc361) under drought stress conditions, ...
