Considering the results of their previous research in 2000, when the shock impacts of production, price levels and money on Iran’s macroeconomic variables such as growth national product (GDP) and price levels were studied, the authors began examining the subject in the open economy. Hence, they entered a new variable i.e. foreign exchange into the model. Having expounded on the model, the auth...
the present study was undertaken to investigate and optimize the possibility of xanthan gum production by xanthomonas campestris ptcc1473 in 500ml shake flasks on the second grade date palm. using an experimental response surface methodology (rsm) coupled with a central composite design (ccd), three major independent variables (nitrogen source, phosphor source and agitation rate) were evaluated...
The exchange rate plays an essential role for firms which export goods and import raw materials. In this paper, the effects of real specific exchange rate fluctuations in imports, exports and aggregate trade on industry sector, chemical and transportation industries outputs in 49 OIC countries were investigated by using a panel data model over 1990-2014. Particularly, this paper presents eviden...
 Understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. In this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. The wells are deviate...
This paper presents a methodology to optimize production rate and focuses on an optimal buffer storage sizing for this purpose. Buffer storages are intermediate semi complete components which their capacity is an important factor in design of production lines and impact on the production line. This methodology with eliminating of some simpler assumptions, assumes that the arrival rate of parts ...
the main objective of this study was to investigate the economic efficiency of investment in sugar beet breeding research in iran. the required information including the value and cost of sugar beet production in 2010 and the budget allocated to the sugar beet breeding research were obtained from the office of statistics and information technology of ministry of jihad-e-agriculture and agricult...
This paper investigates the optimal fiscal policy, pertaining to government spending, considering different productivity of public services in production function and its impact on the optimal tax rate, the optimal rate of government spending, and optimal economic growth rate. Using the VECM model for Iranian economy over 48 years, results show while the current expenditure has a positive and s...
