energy as an important production factor has significant effects on economic growth. identifying the relationship between energy and economic growth can help to improve governmental energy policies. applying ardl and ecm methods, this paper examines the longrun and shortrun causality relationships between (1) energy consumption and economic growth and (2) energy consumption and employment in va...

Abstract: Energy intensity is a measure of the energy efficiency of a nation’s economy. Many factors influence a country’s energy intensity. In this paper, however, we note the effective factors of energy intensity and decompose it by applying Logistic Smooth Transition Regression (LSTR) in Iran during the period 1980- 2013. The main factors are the ratio of the added value of se...

This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

introduction in this study, we aimed to assess the medium-term energy stability of a 6mv elekta compacttm linear accelerator. to the best of our knowledge, this is the first published article to evaluate this linear accelerator in terms of energy stability. as well as investigating the stability of the linear accelerator energy over a period of several weeks, the results will be useful for esti...

the objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of co2 emissions for hazelnut production in guilan province of iran. moreover, the sensitivity analysis was done by marginal physical productivity (mpp) method for energy inputs and energy using linear regression. initial data were collected from 120 orchardists in se...
