the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
In order to evaluate the intensity and stage of drought stress on agronomic characteristics and drought tolerance of common bean (Phaseolus vulgaris L.), a split plot factorial experiment was conducted in a randomized complete block design with three replications at Shahrekord University in 2013 and 2014. Drought stress treatments and levels of irrigation regimes were considered at vegetative g...
introduction safflower) carthamus tinctorius l.) is a tolerant plant to water deficit due to long roots and capability for high water absorption from soil deeper parts. safflower can growth successfully in regions with low soil fertility and temperature. behdani and mosavifar (2011) reported that drought stress affect on yield by reducing yield components and agronomic traits. biofertilizer dur...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
drought, specially in reproductive stage is one of the major constraints, limiting the productivity of crops, including chickpea (cicer arietinum l.). to study the effects of drought during pod set and seed filling stages (terminal drought) on phenology, growth and seed yield of 5 kabuli chickpea genotypes of: arman, jam, hasham, flip93-93 (azad) and ilc482, an experiment was conducted during t...
Despite the high potential of sesame production in the country, its yield and water use efficiency is low. Therefore, identifying genotypes with high grain yield, especially under drought stress conditions, is essential for developing this crop. For this purpose, field experiments were conducted to investigate the qualitative and quantitative response of 21 sesame genotypes to drought stress co...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
introduction drought stress is one of the most yield reduction factor of lima bean where effects on the more than 60% of bean world production. in this regard, solutions that help increase productivity with high water efficiency in this region can change the agricultural crop production. one of the solutions is using organic materials (acid humic). humic acid with linkage of water molecules and...
for assessment of drought stress effects on agro characteristics of 30 lines and 6 wheat cultivars and for introducing of drought tolerant and susceptible ones one trial were established using split plot base of randomized complete block design with two replications, main plots were stress and non-stress condition and sub plots contain 30 lines and six wheat cultivars in the check trial, irriga...
