the interaction between the solute and the solsent molecules play a crucial role in understanding the various molecular processes involved in chemistry and biochemistry, so in this work the potential energy of active site of azurin have been calculated in solvent by the monte carlo simulation. in this paper we present quantitative results of monte carlo calculations of potential energies of ...
this paper surveys economic growth and energy consumption relationship by new econometric methods in different sectors of iran. this study uses panel error correction model and panel co integration and causality tests to investigate short run and long run relationship between energy and value added growth in different sectors of iran’s economy with regards to energy price in the time period of ...
the present paper investigates the effect of production factors, including technology, physical capital and labour on the energy consumption intensity of iran. for this purpose, time series data during the period of (1974-2007) have been analyzed within cobb–douglas production function framework. the results of the study indicate that the technology and the physical capital have caused the aver...
hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...
energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. in this paper, byusing the energy consumption data for the residential sector of shiraz in iran, the effect of built area (ba) andoccupant number (occ) on annual energy consumption (ec) w...
drying of agricultural products is a sophisticated process with high energy consumption. energy needed for sustainable development, is one of the biggest challenges facing humanity. the performance of a heat recovery assisted solar dryer was evaluated in this study. drying time, collector efficiency, energy consumption, solar fraction and energy recovery fraction were investigated at different ...
abstract the aim of this survey is to compare utilization systems (cooperative, private and governmental) methods of energy consumption in soybean production and the evaluation of energy inputs effect in yield of soybean in moghan. for this purpose, the information were collected from 54 private farmers, 14 cooperative members farmers and 14 agro-industry units by questionnaire method. the maxi...
in this article, a study is made to demonstrate the possible utilization of hydrological anergy resources, contained in small water streams and water falls. the total energy, which could be recovered without extensive investments, has been estimated. it is shown that, the energy produced shall meet the total energy requirements of the rural areas of the country. a hystorical background of the u...
twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...
