Compressed air energy storage (CAES) system is one of the highly efficient and low capital cost technologies, which used on a large scale. However, due to multiple operational technical limitations, CAES operation should be incorporated with thermodynamic characteristics. Therefore, in this paper, novel modeling facility integrated hybrid thermal, wind, photovoltaic (PV) farms participate reser...

Different types of iron oxides deposits have been identified along the Khaf – Dorouneh volcanic and plutonic belt in north east of Iran. Kuh-e-Zar is one of these ore deposits known as Fe- oxide gold deposit. The main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the ETM+ data. Data processing has been done by ENVI (Environment for Visualizing...

PURPOSE The prevalence of astigmatism, and the astigmatic axis, and their determinants were evaluated in a rural population of Iran. MATERIALS AND METHODS In a cross-sectional study conducted from May to August 2011, 13 villages in the vicinity of the city of Khaf in northeast Iran were investigated in this study. All the examinations including visual acuity, refraction, slit-lamp biomicrosco...

BACKGROUND Visual impairment is a very important public health problem. In Iran, reports of visual impairment and blindness have been published from the urban population while the prevalence of visual impairment in the rural population has not been reported. The purpose of this study to determine the prevalence and causes of visual impairment, in a rural population in district of based on age a...

Plant cuticles are covered by epicuticular waxes with considerable ultrastructural and chemical diversity and have great systematic significance. Pinus elderica is a rare pine found naturally only in desert environment southeast of Tbilisi (Georgia). This tree have been probably introduced to Iran about 800 years ago and gradually altered in both shape and size in Nashtifan-Khaf, and changed in...

introduction the distribution and dispersion of parks and green spaces is of paramount importance in urban and rural areas. as an indicator in development of nations, green space has environmental, social, cultural, economic and physical dimensions. to be able to perform its roles and functions successfully, green space needs to be properly positioned. this requires spatial suitability analysis...

 Background: One issue of concern in water supply is the quality of water. Measuring the qualitative parameters of water is time-consuming and costly. Predicting these parameters using various models leads to a reduction in related expenses and the presentation of overall and comprehensive statistics for water resource management. Methods: The present study used an artificial neural...
