on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...
Today, the agricultural sector is heavily dependent on energy to meet the growing demand of worldchr('39')s growing population food. This study aims to determine energy indices and equations based on its energy consumption and production. 380 farmers out of total number of 31190 irrigated wheat farmers of Isfahan were selected across the 24 borough of the province (based on Cochranchr('39')s r...
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...
Abstract I n this paper we investigated total energy consumption and its individual forms (oil, natural gas, electricity, renewable energies and coal) relationship with real gross domestic product (GDP) in Iran. We employed Hsiao’s (1981) methodology and annual data which cover 1967-2010 for investigation. The empirical findings indicate there is bidirectional causality ef...
در این تحقیق اثر الکترونگاتیوی برای استخلاف های f, cl, no2 , cf3 برروی آروماتیسیته مولکول بنزن مورد مطالعه قرار گرفته است. nics, ase, homa, homo-lumo energy gapsشاخص هایی هستند که برای نمایش تاثیر استخلاف ها به کار برده می¬شوند.علاوه بر این الکترون های انتقالی توسط پیوند سیگما وپای نیز برای همه مولکول های استخلاف شده مورد نظر محاسبه شده¬اند.نتایج بدست آمده برای این روش ها با یکدیگر متفاوت است.ب...
to investigate the electromagnetic interaction of molecules inside the nanotubes, first, the structure of nanotubes b16n16 was optimized with hybrid density functional theory (b3lyp) using the epr-ii basis set, then cu, cu+, cu++ were located in nanotube and we studied the total energy, band gap energy, electrical potential, changes of band gap energy in terms of total energy and dipole moment ...
