Data on temperature distribution and heat input in a 37mm gun during firing are presented. These results are discussed and compared with theoretical values obtained by using Nordheim, Soodak and Nordheim method of calculation.

This report describes the construction and objective evaluation of the effects of a palatal lift prosthesis upon the speech intelligibility of a single dysarthric patient. Tape recordings of three 50 item word lists were made prior to insertion of the prosthesis (L1), 7 days after insertion of the appliance (L2), and 68 days after insertion of the device (L3). Six judges listened individually to each list and wrote down each word as they heard it from the tape. In all instances the patient was most intelligible after 68 days and least intelligible before the appliance was inserted. Differences between the intelligibility score means for L1 and L3 and L2 and L3 were statistically significant (P
