Wheat is the dominant cereal crop constituting the first staple food in Iran. This paper studies the energy consumption patterns and the relationship between energy inputs and yield for Wheat production in Iranian agriculture during the period 1986 – 2008. The results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 GJ ha-1 in 1986 to 44...

Anomalous transport is ever-present in many disordered organic semiconductor materials. The long-tail behavior observed in the transient photocurrent is a manifestation of anomalous transport. Owing to the fact that anomalous transport has dispersive and non-Gaussian transport dynamics, thus anomalous transport cannot be adequately described by the standard drift-diffusion equation which is a f...

PURPOSE To examine the independent and combined influence of the FTOrs9939609 and the MC4Rrs17782313 polymorphisms on changes in fat mass (FM), resting energy expenditure (REE), leptin, and thyrotropin (TSH) levels, after a 12-week energy-restricted diet intervention in non-morbid premenopausal obese women. METHODS Fat mass (dual X-ray absorptiometry), REE (indirect calorimetry) and plasma le...

optimum working life of tractor and farm machinery employed in potato production in hamadan province was assessed through data envelopment analysis. an input oriented model was applied to determine the optimized machinery system. in this model inputs were the lifetime of tractor as well as seven involved machines including moldboard plow, potato planter, chemical fertilizer spreader, tractor mo...

in developing countries such as iran it was after economic crises and the increase in price of energy carriers and primary resources that industrial ecology was taken into consideration as a method in industrial states. 941 industrial states in iran have a high potential in creating material and energy flow networks with the industrial ecology approach to prevent massive energy loss and valuabl...
