Purpose: Since explosive blasts continue to cause casualties in both civil and military environments, there is a need for an understanding of the mechanisms of blast trauma at the human organ level, plus a more detailed predictive methodology. The primary goal of this research was to develop a finite element model capable of predicting primary blast injury to the lung so as to assist in the d...
Evaluation of range conditions and plant diversity circumstances can help to rangeland managers who establish their managerial approaches on the basis of ecological capabilities of rangeland ecosystems. Hence, surveying of rangelands was done in four sites of northern Alborz Mt. including western Alborz (Masooleh site), west to middle Alborz (Javaherdeh site), central area (Polour site), and ea...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
The legendary Mongolian Plateau has faced increasing environmental challenges associated with overgrazing, and achieving a sustainability transition for this region needs herders’ participation. However, why herders let grasslands be overgrazed even after property rights were privatized—“the tragedy of privatization”—remains unclear. We aimed to understand the causes overgrazing in Xilingol, In...
The forms and dynamics of soil phosphorus can be greatly affected by land use changes, which often involve changes in vegetation cover, biomass production and nutrient cycling in the ecosystem. Present research evaluates the impact of land use change on the amount of total organic and inorganic P, labile, moderately labile and nonlabile P pools in semiarid soils of central Zagros. Samples were ...
