Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Price Daniel, regarding a legal question submitted for clarification: The taxability of coin-operated machines which vend aircraft accident insurance policies.

This report details events of importance reported by the Hanford Operations Office for the week ending June 1, 1949.

A survey has been made of gas decontamination problems at the various installations of the Atomic Energy Commission and the results are reported. Installations visited include: The Hanford Engineer Works, Brookhaven National Laboratory, Argonne National Laboratory, Los Alamos Scientific Laboratory, Iowa State College Institute for Nuclear Research, Knolls Laboratory, and installations at Oak Ridge.

Report presenting flight tests to determine the causes of undesirable dynamic lateral-stability characteristics of an airplane. Various rudder modifications were flight tested with the rudder free and fixed over an indicated airspeed range from approximately 200 to 450 miles per hour. Results regarding rudder-fixed characteristics and rudder-free characteristics are provided.

Report presenting 1/12-size model of a streamline fuselage modified by patterns of air jets or strips on the fuselage bottom. The effects of spacing of jets, length of jet rows, and direction of jets were determined for a simulated chine configuration. Data are presented on resistance, trim, effective hydrodynamic lift, and spray.

Abstract: "Experiments are described wherein uranium metal was heated in ten different refractory materials under conditions approximating those of the uranium J. The refractory crucibles containing the uranium were placed in graphite crucibles and heated in vacuum for four hours at 1800-1850 C by means of an induction furnace. MgO, W, and TiH were found to be unacceptable containers for uranium at these temperatures. BeO, ThO2 and Un showed some reaction with the uranium, whereas UO2, ZrH, CeS, and ThS were only very slightly affected by the uranium during the runs."

This summary of the research progress meeting on June 3, 1948 discusses the following topics: (1) Photomultipliers (L. Wouters); (2) Positive mesons (C.M.G. Lattes); and (3) Background work in 184-inch program (W. Panofsky).

The crystal structures of alloys 61, X-40,X-50, 422-19, 6059, and Vitallium, derived from x-ray diffraction, are discussed. The alloys have been, or are being considered for use in gas turbine applications. The predominant phase was a solid solution of the face centered cubic type of the principal constituent elements.The lattice parameters were found to be between 3.5525 and 3.5662.

Memorandum presenting the results of a wind-tunnel investigation of the low-speed aerodynamic characteristics of two semispan horizontal tails with unswept and 35 degree sweptback plan forms. The two models had an aspect ratio of 4.5, taper ratio of 0.5, and an NACA 64A010 airfoil section. Test results are presented with and without standard roughness applied to their leading edges and with sealed and unsealed radius-nose elevators.

Abstract: In order to calculate the difference between the number of neutrons which cross the x = o plane before and after the channel has been introduced we consider the number of neutrons which cross an element of cylinder wall at a height x1 and in a direction between (see Figure 5).
