The test unit is to simulate the conditions existing in the ``active``section of a pile process tube. This section is loaded with 64 slugs each of length equal to 4.3767 inches, giving an overall active length of 23.34 feet. The figure of 4.3767 inches is the overall length of the aluminum can, rather than that of the slug proper. The calculations tabulated on the accompanying data sheet are representative of the conditions of operation of the ``maximum performance tube`` in the pile. The resistance of a heater element with the specified wall thickness is such as to give a total heating of 552 Kw (corresponding to an 800 mw operating level) with a current of 13,000 amperes flowing through the tube. The heating distribution is a sine curve with a maximum heating of 33.56 Kw/ft. at the center. No attempt will be made to simulate the heating distribution in the aluminum end cap.

The meetings divided into two parts, with reviews of work being done in radiobiology at the University of California by various members of their staff as part one, and, as part two, a meeting conducted by Dr. Shields Warren for Laboratory Directors and their representatives. For the most part papers which were reviewed were summarized material which has appeared in the literature and gave progress to date. Since the purpose of the meeting itself was more for the informal directors meetings, results of the latter are here abstracted.

This report follows and experiment that was performed to determine the visual efficiency of a phosphor when bombarded by alpha particles.

Report presenting an experimental and analytical investigation of the flutter of uniform sweptback cantilever wings. The experiments used groups of wings sweptback by rotating and by shearing with angles of sweep ranging from 0 to 60 degrees. Results regarding the experimental investigation and a discussion and comparison of the analytical and experimental results are provided.

The results of power-off force tests and flight tests of a model with a thin unswept low-aspect-ratio wing are presented. The tests were made with the flaps retracted and deflected. The effects on the lateral flight characteristics of decreasing directional stability were noted.

"A method is developed of easily determining the performance of a compressor system relative to that of the power section for a given altitude. Because compressors, reciprocating engines, and turbines are essentially flow devices, the performance of each of these power-plant components is presented in terms of similar dimensionless ratios. The pressure and temperature changes resulting from restrictions of the charge-air flow and from heat transfer in the ducts connecting the components of the power plant are also expressed by the same dimensionless ratios and the losses are included in the performance of the compressor" (p. 119).
