THE EFFECT OF SUBSTITUTING KCI FOR NaC 1 IN ARTIFICIAL SEA WATER
نویسنده
چکیده
I n a s tudy of bioelectric potent ia ls in Valonia macrophysa, the effects produced b y KC1 are especially interesting in view of the remarkable degree to which this salt is accumula ted in the cell sap. 1 The present repor t deals wi th changes in the P.D. across the p ro top lasm when a cell is t ransferred f rom natura l sea water to certain artificial solutions resembling sea water , in which the concentrat ion of KC1 is var ied f rom 0 to 0.500 tool per liter.

Assessment of the Relationship between Fish Distribution and Physicochemical Parameters of Water in Artificial Reefs (Bandar-E-Salakh and Bandar-E-Bostaneh)
Four components were used to identification the effective physical-chemical factors of water on the variations of dominant fish families. The total variation of the variables was concluded 94/17 % and 90/5%, related to the loaded components in artificial reefs of Bandar-E-Salakh and Bandar-E-Bostaneh respectively.Assessment of the loaded factors in each of the components were identified that ni...

In this study, samples were taken of coastal waters of Kiashahr port. Magnetic desalination consisted of exposing the sample to a Magnetic field and putting the water in physical contact with magnetic nanoparticles which were synthesized with the co-precipitation method. X-ray diffractometer, Fourier transform infrared spectroscopy and field-emission scanning electron microscopy were used for t...
متن کاملTransient Inactivation of Shell Part of Nucleus Accumbens Inhibits and Exacerbates Stress-Induced Metabolic Alterations in Wistar Rats
Introduction: The role of different parts of the extended amygdala in metabolic signs of stress is not well understood. In the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (NAc) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat. Methods: Male Wistar rats (W: 230-250 g) were canuulated un...
