It provides the opinion of the Texas Attorney General, Will Wilson, regarding a legal question submitted for clarification: Authority of the Legislature to appropriate State Building Commission Funds to renovate, equip and repair the exterior of the San Jacinto Memorial Tower and Museum Building.

Report providing an alphabetical listing of the periodicals, both American and foreign, that are currently being received in the Washington (D.C.) Library of the National Bureau of Standards. Approximately 2,000 titles are cited, together with call numbers indicating the location of each in the NBS Washington Library. Although this information was compiled primarily for the use of the Bureau's scientific staff, it is also of value to libraries, scientific and technical organizations, and research workers.

Report documenting the isolation and identification of microorganisms found in the noses, throats, and lower intestines of twenty two dogs. The most frequently observed organisms were E. coli and S. viridans.

Tentative estimates of the sharp''-rising overpressures as a function of duration which represent a lethal hazard to the 70-kg animal 1, 50, and 99% of the time were presented. The predictions were based on interspecies correlations and extrapolations encompassing blast-tolerance data for six mammalian species. The tentative application of the data to indicate human blast tolerance was discussed and relevant uncertainties in the estimates were emphasized. It was also pointed out that biologic tolerance would be different for air-blast pulses having non-ideal wave forms frequently associated with various geometries of exposure. Selected pathophysiological information pertinent to the biological response following blast exposure was given; namely, survival time and selected postshot observations of dogs and goats. (auth)

A total of 993 mice, rats, guinea pigs, and rabbits were exposed to sharp-rising overpressures of various short durations. They were mounted on a concrete pad above which high-explosive charges, ranging in weight from 0.50 oz to 64 lbs, were detonated. Pressure-time measurements were obtained with pencil- type and shock-tube piezo-electric gauges on the pad directly beneath the charges. The duration of the blast waves ranged from 0.40 to 6.8 msec. The LD/sub 50/ pressures were calculated for each species at the different pulse durations. In general, the pressures required to produce 50% lethality rose at the shorter durations. Combining the results of this study with those from previous shock- tube investigations made it possible to define the tolerance of four small-animal species to sharply rising overpressures as a function of pulse duration.

The nature of certain critical lesions seen after exposure to air blast is described. The early lethality characterizing primary and tertiary blast damage is emphasized along with the seriousness of injuries caused by blastenergized debris. Tentative criteria are developed to the end that different levels of environmental variations caused by blast phenomena could be quantitatively related to various levels of biological response. Using the free- field scaling laws and a mathematical model whereby translational velocities can be computed for animate and inanimate objects, the criteria are applied to nuclear explosions ranging in yield from 1 kt to 100 Mt. Thus, it is possible to specify, as a function of yield, the hazard ranges inside which various blast injuries might occur. At these ranges the associated levels of initial nuclear and thermal radiation were computed to allow at least some assessment of the relative importance of all the major hazards from nuclear detonations.

A computational model was used in studies of the biological effects of blast from nuclear explosions. The translational effects of blast waves for objects as small as a 10-mg stone and as large as a 168-lb man were computed from theoretical studies and results were compared to field data for near-ideal blast waves from nuclear explosions. Results indicate that the motion of experimental objects can be satisfactorily predicted for free-field conditions or for window glass in houses. Results were computed for high explosives with free air burst. Parameters computed include velocity, displacement, and acceleration as functions of time for a variety of objects exposed to blast waves with 12 maximum overpressures ranging from 1 to 20 atm. All computations were made for one ton of high explosives burst in free air, but the results may be readily scaled to lower or higher yields and to surface bursts. The missiles are identified by their acceleration coefficients which range from 0.01 to 6.0 ft/sup 2//lb. (C.H.)

This report covers only the tests and operations to be conducted with SNAP 10A system; acceptance tests of SNAP 2 and 8 systems, which will also be conducted in this facility, will be presented in an addendum to be published at a later date.

Report presenting a bibliography on atomic transition probabilities. The papers are arranged according to elements and stages of ionization, and the method employed and class of transitions are indicated behind each reference. Only articles on discrete transitions, both permitted and forbidden, are listed. Also included is a supplementary list of papers dealing with transition probabilities from a general point of view, a table showing the availability of numerical material on the individual atoms and ions, and a table of conversion factors.
