to evaluate antioxidant effects of tomato pomace in broiler diets contained full-fat linseed on the production index, energy and protein efficiency, 396 one-day old ross 308 broilers were randomly allocated to 36 cages for nine dietary treatments with four replicate. this experiment were carried out in a completely randomized design with 3*3 factorial arrangement with three levels of full-fat l...
چکیده : نظریه ی شیوه ی تولید آسیایی ، اولین بار توسط مارکس و سپس در تأیید نظریات او ، در آثار انگلس مطرح شد . این نظریه علاوه بر شیوه تولید ، به بحث درباره ی ماهیت دولت در جوامع آسیایی می پردازد . در این پژوهش ، وجه تولید آسیایی و نظریات پیرامون آن در توسعه نیافتگی ایران ، مورد بحث و بررسی قرار می گیرند . مهمترین نظ the asian production theory was first introduced by marx and then was suppo...
Energy, exergy and exergoeconomic (3E) evaluation are performed to assess the performance of a NH3/H2O cycle integrated with parabolic trough solar collectors (PTSC). To provide continuous electricity produced by generator when solar beam radiation is insufficient a stabilizer temperature subsystem is utilized. The major thermodynamic parameters and climate conditions variations are selected to...
The identification of the most important factors affecting energy intensity with the aim of controlling and managing energy consumption is an important topic. Findings of different empirical studies on the factors affecting energy intensity are inconsistent and this raises uncertainty about the employed models. One of the techniques that conform to these uncertainty conditions of the model is t...
the increasing needs for energy, its high price and its environmental impact on greenhouse gases emission and limited energy resources due to increased research on energy balance in crop production systems. the objective of this research was to compare seedbed preparation and sowing methods in wheat production in kordkoy region with respect to energy use and efficiency. fifteen wheat fields wer...
An experiment with 720 pullets was conducted to investigate the effect of dietary energy levels of pullet and dietary energy and fat of laying ration on subsequent performance parameters during 14-20 and 22-44 weeks of age. In the first period, white leghorn pullets were fed with two diets of low and high density energy (2600 and 3200 Kcal ME/kg). In the lating period (second period), birds, in...
this study aimed to analyze and modeling of energy and performance of dryland chickpea adaptive neuro-fuzzy inference system utilizes (anfis) in dryland chickpea production is done in the city of bukan. data were collected from 70 producers of chickpeas using face to face interviews with farmers and completing the questionnaire specialized. size of land was between 2 and 10 hectares. input fact...
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...
Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...
