Estimate of Armington substitution elasticity for fishery products in Iran

Abstract Nowadays, fishery and aquaculture products form an important fraction of the protein requirement and food of many people on the earth. The hike in prices of these essential products seems necessary owing to the increase in demand and consumption of these products in the country. The price transmission from the international market to the domestic market of tunas was  investigated in t...

Estimate of Armington substitution elasticity for fishery products in Iran

The price transmission from the international market to the domestic market of tunas was investigated in the present research. For this purpose, the elasticity of substitution between tuna imports with goods produced in Iran (Armington Elasticity) was calculated. Armington elasticity reflects a degree of substitution between commodities produced domestically and those produced abroad. A greater...

The Kinetics and Mechanisms of Substitution Reactions of Trans-[Co(en)2CNCl]+ in Binary Mixed Solvent

The kinetics and mechanisms of the substitution reactions of trans-[Co(en)2CNCl]+ with unidentate anions,  , CN¯, I¯,  , Br¯ and SCN¯ in 60% v/v DMF-H2O binary solvent at 40.0±0.2 °C were studied spectrophotometrically. An Id mechanism was assigned for the replacement of chlorine by , CN¯ and I¯, an Ia one for...

Synthesis and Characterization of PMMA with 4 - Carbazole Chromophore Substitution

A new carbazole- containing polymer has been synthesized for further photophysical studies. Efficient synthesis of the substituted methyl methacrylate has been accomplished via microwave assisted synthesis of 1 - chloro - 4-carboxy -5,6, 7, 8- tetrahydrocarbazole followed by further steps, such as reduction of the 4-substituted methyl carboxylate, dechlor...
