Abstract Today, due to the challenges of fossil fuels and environmental crises, use geothermal energy as a renewable source can be useful. Since two wells used for Sabalan power plant have different thermodynamic, in present article, new combined layout based on flash cycles is proposed investigated. In introduced cycle, transcritical Rankin Kalina are also downstream generate more power. addit...

Abstract Regarding disadvantages of fossil fuels, renewables like geothermals can be an eco-friendly source energy. In Iran, the availability fuels and poor policies surrounding subsidies (ranked as first in giving subsidies) caused high energy consumption (1.75 times higher than global average). Energy is mainly provided by that leads to CO 2 emission. This study evaluates trend potentials mor...

in rainfed areas of iran, cereal yields are low, variable and mainly as a result of inadequate and erratic seasonal rainfall and associated management factor, such as late sowing date (or late crop germination). in order to investigate the effects of single irrigation and nitrogen on bread wheat (triticum aestivum l. var. sabalan) a field experiment was conducted as split plot arranged in a ran...

two species of pratylenchoides recovered from the grasslands in sabalan region and one species recovered from natural habitats of tehran are illustrated based on morphological, morphometric and molecular characters. the first species, p. crenicauda is characterized mainly by its lip region with three-four annuli, lateral field with four incisures areolated throughout the length and having rod s...

in this paper, the results of surface and ground water quality monitoring during drilling of three deep exploratory wells in geothermal project in north west of sabalan in meshkinshahr are analyzed. the region has been investigated by various researchers to generate electricity using geothermal energy. drilling in deep geothermal projects, a variety of materials such as cement, bentonite, barit...
