   <dim:field mdschema="dc" element="description" qualifier="abstract">The problem set up as the objective of the present thesis is the detection and measurement of adiabatic thermal changes in barium titanate ceramic at low temperatures. Concurrent with this is the problem of devising experimental techniques suitable for the investigation of this phenomenon in other dielectrics at liquid helium temperatures, a temperature region in which no previous measurements of this type have been made.</dim:field>
