Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...
The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...
issues related to environment are one of the most important issues the communities are facing with in the recent decades. on the other hand, the resource scarcity and the necessity of development for iran and other similar countries makes the issue of efficiency as a solution of the environmental crisis important. in this study, the effects of the variables energy intensity (as one of the most ...
This paper describes energy efficiency indicators and indices of improvements according to type use. The purpose is the monitoring comparing trends in EU-27 countries, Norway Republic Croatia, therefore Croatia have been specially presented for each consumption sectors.
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
This study uses a cross-country panel to examine the determinants of corruption, paying particular attention to political institutions that increase accountability. Even though the theoretical literature has stressed the importance of political institutions in determining corruption, the empirical literature is relatively scarce. Our results confirm the role of political institutions in determi...
