In any hydrologic study, the most important parameter is runoff which necessary for designing hydraulic structure, and determining risk of flood. As there a scare in availability data many sites, hydrologists have developed indirect methods to determine accelerate program watershed management conserving developing water resources management. Many are used estimate runoff; Soil conservation curv...
In this paper, the El-Hames empirical method was used to determine the peak runoff flow in Iranshahr catchment. The El-Hames method is based on morphological parameters and SCS Curve Number of the studied area. The implementing was processed by collecting the required data including soil type and vegetation cover, land use maps, digital elevation model and satellite images from the associated i...
Many watershed models employ the Soil Conservation Service Curve Number (SCS-CN) approach for runoff simulation based on soil and land use information. These implicitly assume that is generated by Hortonian process and; therefore, cannot correctly account effects of topography, variable source area (VSA) and/or moisture distribution in a watershed. This paper presents new distributed CN-VSA met...
Here, we tested the performance of the mitochondrial DNA copy number (mtDNA-CN) in predicting future type 2 diabetes (n = 1108). We used the baseline clinical data (age, sex, body mass index, waist-to-hip ratio, systolic and diastolic blood pressure) and the mtDNA-CN, hemoglobin A1c (A1C) levels and results of oral glucose tolerance test (OGTT) including fasting plasma glucose, 1-hour glucose, ...

Discrimination of regenerative cirrhotic nodules of the liver (CN) from hepatocellular carcinoma (HCC) is sometimes difficult. We examined the utility of AgNOR staining in this context. Fifteen cases of HCC and 25 cases of CN were stained by AgNOR method and the mean AgNOR number for one hundred nuclei in each case was determined. There was a significant difference between the mean AgNOR c...
The spaceM of nondegenerate, properly embedded minimal surfaces in R3 with finite total curvature and fixed topology is an analytic lagrangian submanifold of Cn, where n is the number of ends of the surface. In this paper we give two expressions, one integral and the other pointwise, for the second fundamental form of this submanifold. We also consider the compact boundary case, and we show tha...
extensive flood damages all over the world necessitate its control and operation. hydrologic impacts of land use change appear in many ways such as total runoff, and flood peak flow. this study was performed in 2014 and aimed to investigate the impacts of land use changes on the occurrence of floods in the catchment of boostan dam in golestan province, iran. for this purpose, watershed modeling...
