Garlic is one of the export crops which has a global reputation in terms of taste and quality. Zanjan province produces 23 percent of total garlic crop of Iran and is one the hubs of garlic production in the country. Effective factors on marketing of garlic is not well studied in this province. Therefore, the main purpose of this study is analysis of factors affecting marketing of garlic in zan...
In this study, efficiency of apple producers in Khorasan Province was determined by a cross sectional data of 212 apple producers. Mean technical, allocative, and economic efficiencies were estimated to be around 31, 28, and 9 percent, respectively. A high potential was also detected for increasing these efficiencies. Apple producers’ age and education had positive effects and risk aversion h...

abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Methoxypoly(ethylene glycol) Poly(caprolactone) (mPEG–PCL) copolymers are important synthetic biomedical materials with amphiphilicity, controlled biodegradability, and great biocompatibility. They have great potential application in the fields of nanotechnology, tissue engineering, pharmaceutics, and medicinal chemistry. mPEG–PCL copolymers are biodegradable, biocompatible, and semi-crystallin...
