loess and loess-like deposits cover large areas of golestan province of iran, a well-known region in the world for its high incidence rate of esophageal cancer (ec). despite numerous published works on the possible contributing factors for the observed high incidence rate, very little attention has been given so far to a possible link between the mineralogy of loess deposits in the region and e...

infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. the most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. in present study, through...

in order to study the effects of three operations of rangelands on the properties of vegetation in rangelands, this research was conducted in chaat gonbad, golestan province, iran in 2004. chaat area is located in 50 km of border road of dashlibroun to maravetappeh in north of attract river (border of iran and turkmenistan). the altitude is 70 m, annual rainfall is 170 mm and annual temperature...

BACKGROUND Ectoparasites of mammalian hosts play an important role for transmission of diseases from the host reservoirs to human. The aim of this study was to determine the species composition and infestation parameters for parasitic arthropods associated with Rhombomys opimus. METHODS Ectoparasites of R. opimus were collected from seven endemic district of ZCL in Iran including Shirvan and ...
