abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...

Energy has significant role in socio-economic development of counties any decision on energy sector may affect the broad area in societies. System approach in energy modeling as an efficient method is known by many researchers in management and planning in a country particularly in energy sector. Also System Dynamics is one of the efficient methods, because it has unique abilities. Hence, in th...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

elasticity in an indicator of price sensitivity and its psychological basis has largely been neglected. some scholars in consumer psychology show that advertising decreases price elasticity, while others found a positive relationship between advertising and price elasticity. We hypothesize that two psychological variables, namely set size (in memory) and relative strength of preference (constru...

The energy crisis in recent years has led politicians and major countries around the world to take energy issues differently from the past and replace fossil fuels with renewable energies, including hydroelectricity, to reduce and save energy, controlling supply and demand energy and reduction of pollutant emissions has been widely welcomed. Accordingly, the present study investigates the impac...

In recent years, Iran has increased energy prices somewhat, but because of the very low starting point they remain far below opportunity costs. In this paper we examine two broad issues: First, the estimated impact of the energy price (Gasoline and Jet Fuel) rises on producer prices entire the economy and transportation sub-sectors, and the second, the Estimated of gasoline and jet fuel elastic...
