Abstract. The purpose of this study was to investigate vegetation dynamics and range conditions considering the climatic conditions and soil properties in Haftooman, Khoor and Biabanak deserts, Iran. For this purpose, after determining vegetation types and the associated species, the type of rangeland utilization, grazing season, the livestock type, the other relevant information, vegetation da...

abstract process of evapotranspiration (eto) is a major component of the hydrologic cycle that its accurate estimation plays an important role to achieve sustainable development in water balance, irrigation system design and planning and management of water resources. being a function of different metrological parameters and their interactions, evapotranspiration is a complex, nonlinear phenome...

BACKGROUND Northern Iran (Ardabil) is characterized by a high gastric cancer (GC) rate, whereas Southern Iran (Kerman and Yazd) has a low GC rate. The aim of this study is to verify the potential for pepsinogen I and II to detect atrophic gastritis (AG) in both high and low risk populations for GC. METHODS Sera of blood donors and patients with GC from Ardebil, Kerman and Yazd were used to me...

iabetes mellitus is one of the most common endocrine metabolic disorders. Dual endocrine deficits of impaired insulin action (insulin resistance) and inadequate insulin secretion create an environment of chronic hyperglycemia and general metabolic disorder (1). Development of novel medicine prototypes with systematic and intensive investigations of plants for new agents to treat diabetes mellit...

“In SOSAA, the horizontal wind velocity (u and v), temperature (T ), specific humidity (qv), turbulent kinetic energy (TKE) and the specific dissipation of TKE (ω) are computed every time step (10 s) by prognostic equations. In order to represent the local to synoptic scale effects, u, v, T and qv near and within the canopy are nudged to local measurement data at SMEAR II station with a nudging...

the moisture flux convergence (mfc) and relative humidity in dusty days at different times and levels over the alvand mountain was investigated. the required basic data for the years 2009-2012, including relative humidity, visibility and synoptic codes, were gathered from hamadan synoptic station, while sea level pressure, uwind, vwind and specific humidity data were gathered from ncer/ncar sit...

the aim of this study is to assess some synoptic characteristics of heavy precipitations in southwestern parts of iran and evaluate the relationship between them with the madden-julian oscillation (mjo). research is conducted with regard to distribution of precipitation per month and identifying their steam sources. daily records of the november-april precipitation data in abadan, ahwaz, bandar...
