in regard to both implementation of the second phase of targeted subsidises and the effect of inflation resulted from first phase of it on economic of country, inflation content estimation on economic of country especially agriculture sector is necessary. in this research effect of increasing price of energy carriers on inflation in various reproduction sectors such as agriculture was investiga...

the process of price setting in market for goods &services; along with the phenomenon of price ceiling in production factors market with distort the equilibrium & result in price gap in the economy, which in turn generates excess demand & necessitate the permanent sources of finance (subsidy) for its satisfaction, failing which may lead to budget deficit & embarrass the maintenance of policy ex...

In this study, the energy consumption in the food and beverage industries of Iran was investigated. The energy consumption in this sector was modeled using artificial neural network (ANN), response surface methodology (RSM) and genetic algorithm (GA). First, the input data to the model were calculated according to the statistical source, balance-sheets and the method proposed in this paper. It ...

due to many important applications, the group iii-nitride semiconductors have recently attractedremarkable attention among semiconductor researchers and engineers. in this paper, we report on the impact of extrinsic and temporal carriers on the screening of polarization internal fields. the optical efficiency of gan/algan multiple quantum well (mqw) nanostructures were studied by means of photo...

The carriers of electric current in a metal are quasiparticles dressed by electronelectron interactions, which have a larger effective mass m* and a smaller quasiparticle weight z than non-interacting carriers. If the momentum dependence of the self-energy can be neglected, the effective mass enhancement and quasiparticle weight of quasiparticles at the Fermi energy are simply related by z = m/...
