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...

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...

MOTOKAWA and Mita (1942) discovered a subsidiary positive deflection preceding the b-wave of the ERG in a moderately light-adapted human eye. They called it "x-wave", but gave no interpretation of it. Independently of these Japanese authors, Adrian (1945) rediscovered the phenomenon. He established that the b-wave (which he called "scotopic response") is absent in red light and in a state of li...

INVESTIGATIONS made by Motokawa and Mita (1942), Adrian (1945), Gastaut (1949), Johnson (1949), Schubert and Bornschein (1952), Armington (1952), Armington, Johnson, and Riggs (1952), Bornschein (1953), Burian (1954), and Auerbach and Burian (1955), and by other investigators, have revealed that-under suitable conditions of examination-the human electroretinogram (ERG) normally consists of a ph...
