Supercooling and Freezing Tolerant Animals
Subzero temperatures may adversely affect animals by their direct lethal effects and by the damage caused by ice formation (Ramløv, 2000). Animals deal with the latter by three basic strategies. Freeze avoiding animals prevent ice formation in their bodies and supercool, keeping their body fluids liquid at temperatures below their melting point, but die if freezing occurs. In contrast, freezing...
متن کاملFreezing Point Depression of Plasma ‡
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...

متن کاملMeasurement of freezing point depression of water in glass capillaries and the associated ice front shape.
Variations of the Kelvin equation [W. Thomson, Philos. Mag. 42, 448 (1871)] to describe the freezing point depression of water in capillaries exist in the literature. The differing equations, coupled with the uncertainty in input parameters, lead to various predictions. The difference between the predictions may become substantial when the capillary size decreases much below micron dimensions. ...
متن کاملArabidopsis thaliana avoids freezing by supercooling.
Arabidopsis thaliana (L.) Heynh. has been described as a freezing-tolerant species based on freezing-resistance assays. Nonetheless, this type of experiment does not discriminate between freezing-tolerance and freezing-avoidance mechanisms. The purpose of this paper was to determine which of these two freezing-resistance mechanisms is responsible for freezing resistance in A. thaliana. This was...
