BACKGROUND Previous studies have revealed significant differences between populations for genotypic frequencies of glutathione S-transferase T1 (GSTT1) and M1 (GSTM1) polymorphisms. In order to find the frequency of the null genotypes of GSTM1 and GSTT1 in Iranian populations, the present study was carried out. METHODS The total study subjects consisted of 1340 unrelated healthy Muslims/Irani...

abstract among different water usage in iran, agricultural sector with 94 percent is the largest water user. considering the share of agriculture in water usage, farmers are the main factor in water resources management. therefore, optimal utilization of irrigation and drainage networks would depend on farmers’ effective role. due to the limited water resources in different country regions, inc...

Introduction: There is a high prevalence of hemoglobinopathies, including thalassemia, in Sistan and Baluchistan province Iran. It important to appropriately screen young adults control the birth new cases thalassemia. In many less-equipped centers, this practice only relies on cell blood count. This study investigated hematological parameters referring Central Laboratory Sistan, Zabol, for pre...

this paper uses the concept of meta-frontier to investigate the relationship between meta technology ratios (mtr) and different varieties in datepalms including; mazafati, rabi and zardan that are produced widely in sistan and baluchestan province of iran. we used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...

abstract background and purpose:the rapid urbanization and industrialization in many parts of the world have led to the accumulation of heavy metals in the terrestrial environment and pose a serious threat to human health. in this study, a broad assessment was conducted to estimate the levels of heavy metals in groundwater in sistan and baluchestan via geographic information system (gis), iran,...

by far, different models for determining the relationship between the flow rate  and amount of precipitation have been developed. many models are based on regression models with limited assumptions. one of the most common methods for estimating  sediment of rivers is sediment rating curve. for better estimation of the amount of sediment based of sediment curve  rating equation, it is possible t...
