In order to determine and evaluate the mechanization indices, including energy and economic, in production of greenhouse cucumber and tomato, a study was carried out using sequential design- factorial with three replications in Khuzestan province, Iran, during 2011-2012. The greenhouse structures and production methods in all the systems were similar. The evaluated treatments included two culti...
The present paper integrates neoclassical offer curves and production theory, introducing utility maximization and trade levels into the comparative static factor proportions model. The paper analyzes production conditions that determine the Metzler paradox that a tariff could lower the tariff inclusive import price. The model provides a more complete link between neoclassical and factor propor...
The land slug, Incilaria bilineata, was shown to contain a large amount of 1-O-alkyl-2-acyl (long chain)-sn-glycero-3-phosphocholine, which accounts for as much as 47% of the choline glycerophospholipid fraction. Since this unique either phospholipid has been regarded as a stored precursor form of platelet-activating factor (PAF) in mammalian inflammatory cells, we examined the possibility of t...
Abstract Human insulin-like growth factor I (hIGF-I) is a kind of growth factor with clinical significance in medicine. The major objective of this study is over- production of recombinant human insulin-like growth factor I( rhIGF-I) through a developed process by recruiting effective factors in order to achieve the most recombinant protein. Up to now E. coli expression system has been widely us...

to calculate partial and total productivity of production factors in broiler farms in yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. to measure productivity, the cobb-douglas production function was estimated using classic and fuzzy regression met...
