SRE CONTROL ROD SHIELDING REQUIREMENTS
Data taken on radiation traverse of the Mark 1 control rod were analyzed. Future radiation levels for all SRE control and safety rods were predicted from this. The shielding necessary to ship a complete rod and that necessary to protect a person doing maintenance work on these rods were calculated. The unshielded gamma dose rate 1 cm from the surface of the most highly activated portion of the control rod was calculated to be 5.0 x 10/sup 4/ r/hr 14 days after shutdown following an extended power run of 90 days duration. (M.C.G.)

RADIATION CREEP
Several theories of metal creep and radiation damage are studied, in order to determine whether creep rates under various conditions of irradiation can be predicted theoretically. It is found that if the creep is of the recovery type, and if the diffusion coefficient for radiationinduced vacancies is large enough, creep rates may be increased within a limited temperature range. Otherwise, radiation has no effect on creep rates. (T.F.H.)

RECONNAISSANCE FOR URANIUM IN THE CUZCO-AYAVIRI REGION, SOUTHERN PERU
Geologic and radiometric investigations of the CuzcoAyaviri region in southern Peru were made in a search for geologic features or structures which might be favorable for the occurrence of uranium. Outcrops consist of Lower Paleozoic sedimentary and metamorphic rocks; Permian to Carboniferous volcanic flows, tuffs, breccia and agglomerate, together with sedimentary rocks; and Cretaceous and sedimentary rocks. Cretaceous to Tertiary igneous rocks are acidic intrusives and extrusive rhyolite, dacite and trachyte. Tertiary to Quaternary volcanic tuffs, breccias and agglomerates are also present. Although no anomalous radioactivity was observed, favorable geologic features for the occurrence of uranium were noted at two localities. (auth)

AIRBLAST OVERPRESSURE AND DYNAMIC PRESSURE OVER VARIOUS SURFACES
Static overpressure and dynamic pressure versus time over surfaces processing different physical properties were measured on two tower shots, 6 and 12. On Shot 12, three surfaces were provided: the natural desert, a water surface consisting of a flooded area, and an asphalt surface. On Shot 6, desert and asphalt areas only were available. There were 123 channels of instrumentation installed for Shot 12, and 24 for Shot 6. From the data, a system of wave-form classification was devised for overpressure and dynamic-pressure- versus-time measurements. Incorporation of this system into data analysios indicates that it is possible for an ideal peak pressure to be identified with a nonideal wave form. Introducing both variables, wave form and peak pressure, into analyses reduces ambiguioties associoated with comparing results of different nuclear tests. The data show the effect of the nature of the surface upon airblast phenomena from a nuclear explosion. The effects of surface conditions upon shock phenomena are made more understandable by a review of temperature computatioons, using shock wave parameters in addition to an analysis based upon the arrioval time of the thermal pulse. A phenomenological discussion of precursor formation is presented, and comparisons are made using data from all …

RECONNAISSANCE FOR URANIUM IN THE PROVINCES OF AYABACA AND HUANCA-BAMBA, DEPARTMENT OF PIURA, PERU
In 1957 a radiometric examination of rock outcrops in the Ayabaca and Huancabamba areas of northwestern Peru was made in conjunction with a geologic search for structures favorable for the occurrence of uranium minerals. No anomalous radioactivity was detected, and the geologic setting is believed to be generally unfavorable for uranium mineralization. (auth)

Invocation

Recording of Hugh Le Caine's Invocation. The piece opens with a trio of three recorded sounds: a glass that is broken with a hammer, a ping-pong ball hitting a racket, and a drop of water. These sounds are the "instruments" used throughout the piece. Drips are configured as fast ascending and descending glissandi. A series of chords is constructed from a sustained movement of glass stamps. The sound of the ping-pong ball - from the left to the right - gradually accelerates. Severe rumbling and sharp joints appears as sudden changes in channels multiply. The introduction of these gestures disrupts the orderly progression of loops and the inclusion of small strips of paper connected to the ribbon which produces rough and jerky sounds further accentuate this breaking effect. Towards the end of the piece, sustained sounds are played out in a chord, but as soon as this effect is installed, the tape slows down and stops, as if someone had unplugged the music player. Then we hear a particularly violent sound of glass breaking.
