in this study some thermodynamic parameters including freezing point, boiling point and the vapor pressure of urmia lake salt water were investigated as some important environmentally monitored physicochemical properties of urmia lake. in this regard salt concentration is chiefly responsible for the modification of the thermodynamic properties of urmia lake water which affects its overall en...

In an earlier paper2 we have reported results demonstrating that changing the concentrations of the carbon dioxide and oxygen with which the bloods of sheep and goats are equilibrated has a measurable effect on the total osmotic pressure of the true plasma. At constant oxygenation the osmotic pressure of the true plasma is increased 0.9 milliosmoles/Kg H20 for each millimole of C02/Kg H20 added...

 We performed molecular dynamics simulations using the coarse-grained model to study the freezing behavior of pure water and 14% water-salt mixture in a wide range of temperatures for a very long time around 50 nanoseconds. For the salty water, an interface in nanoscale was used. For both systems, the f...

Liquid-like regions (LLRs) are found at the surfaces and grain boundaries of ice and as inclusions within ice. These regions contain most of the solutes in ice and can be (photo)chemically active hotspots in natural snow and ice systems. If we assume all solutes partition into LLRs as a solution freezes, freezing-point depression predicts that the concentration of a solute in LLRs is higher tha...

Buffered NaCl solutions hypertonic to rabbit serum were prepared and freezing point depressions of each determined after dilution with measured amounts of water. Freezing point depression of these dilutions was a linear function of the amount of water added. One ml. of rabbit red cells was added to each 4 ml. of the hypertonic solutions and after incubation at 38 degrees C. for 30 minutes the m...

When investigating the freezing behaviour (by thermal analysis) of the glycerol-extracted adductor muscle of Mytilus edulis it was observed that the temperature of ice formation in the muscular tissue was up to 1.5 degrees C lower than the freezing point of the embedding liquid, a 0.25 N KCl solution with pH = 4.9 with which the tissue had been equilibrated prior to the freezing experiment. A s...
