The present study, in addition to investigating the impacts of GDP and gasoil consumption as the biggest consumed petroleum product in Iranian transportation sector, by introducing petroleum product intensity, studied their effects on CO2 emission in this sector. To evaluate the impact of the variables, we estimated an autoregressive distributed lag (ARDL) model between the years 1996 and 201...
The scope of the CORE concept is the development of an action-ready economically viable technical solution to mitigate the environmental, and societal effects of green house gas emissions (GHG) resulting from internal combustion (IC) engines. The developed and proposed technology has been deemed Combustion of Optimized Reactivity in Engines, or CORE for short. In the United States, the transpor...
In this paper, collapse behavior of simple and reinforced thin-walled channel- section beams, subjected to three- point bending, is investigated. Many simple channel- section beams of different geometry and some reinforced ones were tested, and their strengths after collapse were obtained thoroughly. Since the available theories in this area are complicated and little attention has been paid to...
We present a calculation of the cross section for the process e+e− → W±H∓ in the minimal supersymmetric standard model (MSSM) and the Two Higgs Doublet Model (THDM). We study the basic features of the MSSM prediction for some distinctive parameter scenarios. We find large effects from virtual squarks for scenarios with large mixing in the stop-sector which can lead to a cross section vastly dif...
In this research, we attempt to investigate the effect of economic boom and recession on environmental pollution in Iran through an asymmetric approach. To this end, an autoregressive approach with nonlinear distributive pause was used with the data for the period (1971-2017) to explain and describe the asymmetry; Accordingly, a basic model (for the entire economy) and three partial patterns (f...
over the coming decades, global change will have an impact on food and water security and there are strong indications that developing countries will bear the brunt of adverse consequences from climate change. agricultural sector is the most vulnerable to climate change, because of its dependence on water and temperature conditions. consequently, it is important to understand the impacts of cli...

With respect to targeting high economic growth rate and lack of financial resources, identifying key sectors and measuring inter-sectoral interactions in in the economy is becoming increasingly important. There is no doubt that the electricity sector in the economy plays a vital role in the development of other sub-sectors and it is expected that there will be a positive relationship between th...
Background and Objectives: Social marketing is a method that acts through identifying the needs and demands of the audience and specifying the components of the behavioral market using the results of developmental research. So far, social marketing has not been used to involve the private sector in the tuberculosis (TB) control program. The aim of this study was to design a Public-Private Mix (...
These days, limited energy resources, and also the cost of investment in new and renewable energy is very costly and uneconomical. In the industrial sector, especially energy-intensive industries such as steel, finding appropriate solutions to update the technology, production and reduce energy consumption in this sector is very important. The main aim of this study is the identification an...
