abstract this study set out to compare the effect of modality of presentation (subtitled vs. auditory) in the comprehension of verbal content of documentary films among iranian efl students. to this end, (30 male 30 female) students were chosen from two schools. after their homogeneity was established, the students attended the listening sessions to watch five documentary films over t...

 To evaluate the resistance of promising chickpea ecotypes to freezing temperatures, an experiment with eight promising cold tolerant chickpea was performed. The ecotypes consisting of 4301, 4322, 4360, 4361, 4366, 4380, 4715, 4816 along with a sensitive one (304) were sown in pots at natural conditions. All the chickpea ecotypes were exposed to freezing temp eratures at controlled conditions d...

writing as a productive skill requires practice in the basic sub-skills of vocabulary and grammar. in fact, grammar has been viewed as the core of programs in writing classes to help the students put the elements of sentence together and combine sentences of specific lengths to come up with an error-free work of art. conceptualizing l2 writing in this way introduces writing as a product and enc...

Poplars are fast-growing species that were planted pure in the past. Mixed plantations of poplar with nitrogen fixing species have been recommended recently to increase the soil fertility. In this study, Ameraican poplar (Populus deltoids) has been planted with Peanut (Arachic hypogaea). The research was carried out on the base of randomized complete block design with five treatments and three ...

A field experiment was carried out during the 2013-2014 growing season in Lorestan Province (Iran) to evaluate the effect of three planting densities (30, 55, and 83 plant.m-2) on growth indices and grain yield of four chickpea cultivars (Azad, Hashem, Arman and ILC482) under the fall dry land farming condition. The experiment design was factorial based on a randomized complete block design (RC...

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

In order to evaluate drought tolerance indices in chickpea, determination of the best indicator of drought tolerance and identifying tolerant cultivars in water limited condition, a randomized complete block design (RCBD) with three replications and 20 chickpea genotypes was used under irrigation and rainfed conditions at research farm of College of Agriculture, Razi University, Kermanshah.
