Conductance of potassium halides near the temperature of maximum density of water

AbstractThe conductances of dilute aqueous solutions of KCl, KBr, and KI have been measured over the temperature range 2 to 8°C and have been analyzed by the Fuoss-Hsia equation. The ionic Walden products at infinite dilution have been discussed in terms of local viscosity.

Influence of body temperature on the set-up and recovery of noise-induced cochlea damage

SummaryHypothermia during exposure to noise reduced hair-cell damage which, on the contrary, was prevented from recovering by narcosis and hypothermia.Hyperthermia is apparently able to eliminate the narcosisdependent limitation of metabolism.
