Energy consumption efficiency is one of the most important concerns in urban communities allotted more than 70 percent of Iran’s population to itself. Since energy efficiency index that is one of the targeted components in resistance economy policies has been reduces, it is necessary to design and adopt comprehensive, efficient, and integrated policies in order to improve efficiency and product...
Background and Aim: The prevalence of chronic diseases can be reduced by correcting people's food habits. Therefore, the purpose of this study was to assess the explanatory power of the Expectation-Confirmation Model for the intention to continue fruit and vegetable consumption. Materials and Methods: This descriptive-analytic study included 332 elderly people with a history of receiving healt...
this paper extends endogenous growth models through augmenting it with government budget and oil revenues as well as the effect of public investment efficiency on long run growth of private and government consumption and import for an oil producing economy. based on the extracted model, the optimal growth rate of government current expenditure (or consumption) has a positive relation with the e...
In this study the causality relationship among variables in chicken and beef markets were investigated based on annual data from 1974 to 2004 in the I.S. of Iran. For this purpose, causality algorithms emerging from directed acyclic graphs were used in two cases, one based on co- integration analysis and innovation correlation matrix of Vector Error Correction Model (VECM) and the other using d...

background & aim: depression is a chronic and overwhelming disorder. one of the factors that could prevent the occurrence of depression is tea consumption. considering the controversial results of previous studies, the aim of this systematic and meta-analysis review study was to answer this question that whether tea consumption could decrease the risk of depression. methods & materials : by sea...
Train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. On the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. First, we propose a fuzzy energy ...
Ever-increasing dependence of human life on energy has made this factor play a critically crucial role either potentially or actively in the functions of various economic sectors of countries. Therefore, the people in charge of any country should try to make exact forecasting of energy consumption and make correct planning about its consumption in a way to optimally control supply-demand parame...
Dominance of arid and semiarid climate in a vast area of Iran along with the water consumption growth necessitates a more sophisticated planning, a more efficient operation towards an optimal allocation and conservation of water resources in the country. In recent decades many countries, including Iran, have adopted increasing block tariffs for domestic water management. This policy is based on...
