kashan aquifer is adjacent to salt lake. because of this adjacency, the saline water of the lake has moved to the aquifer. in this study groundwater quality of the aquifer was simulated using artificial neural network (ann) model. for this purpose, the dominant ion of water was first determined by piper diagram. results showed that the sodium chloride is the dominant ion of water and so it was ...

with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

containing 1 ml. 15 % glycerol solution, 1-0 ml. 0-1 M-sodium acetate, 0-5 ml. 0-3 M-bicarbonate solution and 0 5 ml. of the enzyme solution. Occurrence of the back reaction would have given rise to an uptake of C02 from the system, but in fact no such uptake was observed. Under these conditions, therefore, no back reaction takes place, so that the incompleteness ofthe de-esterification cannot ...

abstract alstroemeria is one of the most important cut flowers in the world which is multiplicated by rhizome explants in in vitro conditions . the major problem in using rhizome explants is fungal and bacterial contamination which inhibit the preparation of strill explants. therefor in this experiment, the effect of disinfecting compounds like sodium hypochlorite, mercury chloride, nano silver...

nabro3 combined with nh4cl is found to be an efficient reagent for the transformation of sulfides into sulfoxides in aqueous and under mild conditions.

AIM Identifying differences in plasma metabolic profiling between Lp-PLA2 279VV and 279FF in individuals without metabolic syndrome (MetS) can be used to elucidate the roles of novel Lp-PLA2 activities in normal physiological processes. METHODS Non-MetS individuals with 279FF (n=36) and age-, sex- and BMI-matched VV subjects (n=36) were included in this analysis. RESULTS The FF subjects exh...

The present study compared the postweaning blood pressures and body weights of borderline hypertensive rats exposed to a high (8%) sodium chloride maternal diet either from conception to weaning or only during the weaning period with borderline hypertensive rats consistently exposed to a normal (1%) sodium chloride maternal diet. Because the effects of early sodium chloride exposure may be most...

Human toxicity High NaCl intake without corresponding intake of water can lead to hypernatremia: the ratio of sodium to water exceeds normal, and both the plasma sodium concentration and the total body sodium increase. Consequently, the balance of extracellular and intracellular osmolality is disturbed, which can result in several clinical symptoms, like excessive thirst, weakness, headache, ir...
