We propose a simple theoretical formula for describing the refractive indices in binary liquid mixtures containing salt ions. Our theory is based on the Clausius-Mossotti equation; it gives the refractive index of the mixture in terms of the refractive indices of the pure liquids and the polarizability of the ionic species, by properly accounting for the volume change upon mixing. The theoretic...

This study was carried out to study the possibility of salt tolerance induction in two cultivars of sorghum by exogenous application of different levels (0, 50 mM and 100 mM) of proline. Salt treatments (100 mM) adversely affected the germination percentage, growth and chlorophyll contents of both cultivars. However, applications of proline alleviated the adverse effects of salt stress. However...

the objective of this research was to evaluate the effect of different concentration of salicylic acid on enhancement germination characteristics of sanguisorba minor l. under salt and drought stress. the experimental design was factorial arranged in a completely randomized block design with four replications. treatment were combination of 5 levels of salt and drought stress, separately (0, -0....

The persistence length of charged linear polymers in semidilute solution must increase substantially upon addition of salt. For very long polymers the persistence length increases as the salt concentration to the 5/2 power provided this salt concentration is not too large. In deriving this scaling we correct our previous prediction in light of a recent paper by Barrat and Joanny, and in agreeme...

In this paper, removal of chromium(VI) from aqueous solution has been researched using reverse osmosis. The influence of transmembrane pressure and feed concentration on permeate flux, water recovery, permeate concentration, and salt rejection was studied. The results showed that according to the variation of transmembrane pressure and feed concentration, the permeate flux and salt rejection we...

The severity of Zn deficiency increased with increase in soil exchangeable sodium percentage (ESP) with salt sensitive variety M1-48 scoring 6 at ESP 62 as against only score 3 by salt tolerant variety Pokkali under similar soil conditions. Strikingly, zinc contents were much higher in salt tolerant variety than in salt sensitive one. Zinc application increased zinc concentration in the roots b...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...
