due to the being in the desert bar and ecosystem sensitivity to water , water management in the agricultural sector of the iran is one of the priorities of managers and planners of this section. therefore accurate modeling of the production function, for policies to increase efficiency and reduce the use of inputs, as well as forecasts for the timely supply with low cost, is of utmost importanc...
in recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...
The purpose of this article is to investigate the impact of electricity tariffs in the domestic and industrial sectors on electricity consumption and macroeconomic variables. In this regard, statistical data for the period 1991-2020 based on seasonal frequency and dynamic stochastic general equilibrium approach (DSGE) have been used. In this study, it is assumed that there is a section in the h...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
considerable consequence of households’ consumption expenditure changes is on energy using in agricultural sector and in other economical sectors. the main objective of this paper was to study of consequences increasing rural and urban households expenditures on changing of energy using in agricultural sector and on producing of environmental pollutants in khorasan razavi province. for this pur...
Given the unlimited needs of mankind and the limited resources available, human beings have always been thinking about how to use the available resources and facilities optimally. Energy plays an important role in economic activities and it is of great importance in agriculture. Over the past four decades, energy consumption in the agricultural sector has increased tremendously. In Iran, energy...
according to international trade theories, countries attempt to produce and export commodities with their abundant resources. iran has great energy resources and availability of inexpensive energy input has increased energy consumption per capita in manufacturing sector as well as in consuming sector. relying on low energy price, manufacturers employ energy-intensive methods for producing and e...
the paper presents an analysis of both energy intensity and energy demand for the italianindustrial sector. the aim of the paper is twofold: making a decomposition of energy intensity at the aggregate level and modeling energy demand at the firm level. the decomposition of energy intensity shows different patterns for the different sub-sectors in the period of interest. in the micro approach, p...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Nowadays, demand for energy is one of the important and applicable issues in different countries. Energy demand is of great importance from the viewpoints devastating impact on the environment and in terms of economic costs. The household sector is the major consumer of energy study of the factors influencing the energy consumption can have beneficial results in terms of the application of appr...
