1. Dunaliella viridis Teodoresco thrives equally well in solutions of NaCl 1 to 4 mol and pH 6 to 9. 2. The organism is sensitive to calcium and magnesium, especially in acid medium. 3. Calcium and magnesium are antagonistic. In a molar solution of NaCl the antagonistic relation Mg:Ca is 4 to 5. In a 4 molar solution of NaCl the proportion becomes many times as great (20:1). 4. Although the str...

Fischer-344 (F-344) rats differ from other common rat strains in that they fail to show any preference for NaCl at any concentration in two-bottle preference tests. Because 100 microM amiloride partially blocks the NaCl-evoked chorda tympani (CT) response in electrophysiological studies, we tested NaCl preference (0.068-0.273 M) in F-344 rats with and without 100 microM amiloride solution as th...

The jelly surrounding the eggs of the starfish, Asterias forbesi, is insoluble in normal sea water, but rapidly swells and dissolves when the eggs are washed in a pure isotonic solution of NaCl. In the presence of a small proportion of CaCl(2) this solvent and disintegrative action of the NaCl solution is entirely prevented, and in the mixed solution the jelly exhibits the same insolubility and...

Effect of nano TiO2 particles on the corrosion properties of an epoxy based coatings was investigated. Coatings and nano Titania were applied on standard phosphated steel panels by cathodic electrodeposition simultaneously. The coated panels were immerged in 3.5 NaCl solution for 2880 hours 120 days. The SEM and EIS technique were used to investigate the electrodeposion of nano Titania particle...

Density and Ultrasonic velocity Sucrose in 1M NaCl at 298.15K, 303.15K, 308.15K and 313.15K have been measured. Various ultrasonic and solution parameters such as adiabatic compressibility, change and relative change in adiabatic compressibility, acoustic impedance, available volume and free length have been calculated using these data. The present investigation has been used to exploit the pos...

(a) The responses of the vomeronasal organ to general odorants in the turtle, Geoclemys reevesii, were measured by recording the accessory olfactory bulbar responses. The threshold concentrations of the vomeronasal responses to various odorants were similar to those in main olfactory bulbar responses, indicating that vomeronasal cells lacking cilia and olfactory cells having many cilia have sim...

It is found that the electrochemical corrosion of a silver sheet anode in NaCl solution gives rise to a fast and continuous way of generating AgCl nanocubes with good uniform morphology. We examined the factors affecting the size and morphologies of AgCl nanocubes, which include the applied voltage, the concentration of NaCl, and that of Na2SO4 added to enhance the conductivity of the NaCl solu...

Asthmatics are known to react to inhaled hyperosmolar solution. Therefore, the effect of hyperosmolar salt solutions on tight junctions of the airway epithelium was investigated by electron microscopy. Rat trachea was perfused with different concentrations of sodium chloride (NaCl) and then fixed from the luminal side with glutaraldehyde to which the electron dense tracer lanthanum chloride had...

ABSTRACT: Fermented cucumber is a traditional lactic acid fermentation that is related to the presence of microorganisms. In this study, the use of suitable L. plantarum starter culture with L.bulgaricus and S. thermophilus to improve the cucumber fermentation process with high quality has been studied. Cucumbers in brine containing 4 to 6% NaCl and 0.2 to 0.4% Inulin (w/v) were inoculated with...

This paper describes the research carried out to develop a process to increase the NaCl percentage of crude salt which is obtained from the conventional solar evaporation process. In this study refined salt was produced from crude solar salt by a chemicophysical method which consists of coagulation, precipitation and filtration. Initially crude salt crystals were crushed and dissolved in water....
