Coefficient of Thermal Conduction: Homogenized Tissues: Thermal Conduction and the Rate of Blood Flow [PDF]

Nature, 1962
THE coefficient of thermal conductivity has already been measured for slices of various dog tissues1, and found to vary from 0.6 × 10−3 for fresh lung to 5.5 × 10−3 for fresh muscle. The same apparatus can be used for measuring K for homogenized tissues; in general, these have values of K which vary less from each other than do those for tissue slices.
