heavy metal pollution is a worldwide problem with serious environmental consequences. the objective of the present experiment was to investigate whether arginine as nitric oxide precursor and or polyamines substrate can decrease the destructive effects of oxidative stress induced by nickel contamination in hyoscyamus niger plant. in this study the effects of arginine pretreatment on alkaloid co...
Plant tissue culture techniques were used to study the effect of NaCl on tropane alkaloids accumulation and proline content of both Datura metel and Datura stramonium. Callus cultures were established for both Datura species. However, MS medium supplemented with 1mg/l of both BA and NAA was the best for callus production in D. metel, while MS supplemented wit...
this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...

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...
drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...
in this research, effect of vermicompost and plant growth promoting rhizobacteria (pgpr) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at karaj research institute of forest and rangelands. experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...
application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. nanofertilizers application could be a suitable way to reduce these problems. accordingly, in order to assess the silicon nanopar...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
In order to study the effect of chitosan on growth and some biochemical characteristics of chickpea under salinity stress condition a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 1392, as factorial arrangement in completely randomized design with three replications. Experimental factors included salinity (0, 4, 6 and 8 dS/m) and level of chitosan (0, 0.1, 0.2%, a...
