[1] Large topographic belts along convergent margins have been recognized with the ability to slowdown the kinematics of subduction over geologically short time periods (i.e., few Myr), because their associated gravitational spreading provides significant resistive force within the framework of plate tectonics. The record of past and present-day plate kinematics provides important constraints o...

Present research was conducted with the aim of designing and explaining the model of organizational toxicity measurement in South Zagros Oil and Gas Production Company through the mixed method (quantitative and qualitative). In terms of purpose and method, this research was in the category of applied and descriptive researches, respectively. The number of 32 experts from the South Zagros Oil ...

In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the semi-circular bund affecting soil quality and moisture storage. The selected forest site is loca...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

the life table parameters of schizaphis graminum (rondani) (hemiptera: aphididae) on four commercial cultivars of wheat (kohdasht, pastor, tajan and zagros) were determined in laboratory conditions. fertility life table were constructed using age-specific survivorship (lx) and age-specific fecundity (mx) and subsequently analyzed using jackknife method and anova. there were significant differen...
