Abstract : The series of heat capacity measurements of various bovine tissues at liquid nitrogen temperatures were completed. The classical heat capacity equation for mixtures was used to predict the heat capacities of bovine muscle (heart), kidney, brain and liver. An experiment was performed to measure the heat release rate in simulated tissue material in which carbonyl iron powder was suspended. A high frequency induction field generated volumetric heat sources which would appreciably increase frozen tissue thaw rates. (Author)
