Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Date: December 1961
Creator: Lawson, Katheryn Emanuel & Crosby, G. A.
Description: Abstract: "The symmetries of infinite polymer chain molecules are discussed using the concept of line groups. Explicit directions are given for obtaining the irreducible representations of line groups employing the formalism developed for three-dimensional space groups. Line groups containing primitive and nonprimitive operations are discussed. Detailed considerations of the line group Vh are given with specific applications to the polyethylene molecule. Directions for generating symmetry-adapted vibrational coordinates for chain molecules are outlined."

A Scale-Model Experiment of the Crater Produced Through Terrain of Randomly Varying Elevation by Row Charges

A Scale-Model Experiment of the Crater Produced Through Terrain of Randomly Varying Elevation by Row Charges

Date: November 1962
Creator: Vortman, Luke J.
Description: Abstract: "A scale-model experiment was made to check the application of charge spacing rules developed from earlier studies to terrain of randomly varying elevation. Since a prominent possible peacetime use of nuclear explosives is the excavation of a trans-Isthmian canal, the model used was a portion of such a route. The experiment resulted in nearly the desired linear crater dimensions; the spacing rules developed for level trerain give a satisfactory channel when applied to terrain with elevations varying in random fashion."

Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Construction of a Sea-Level, Transisthmian Canal Using Nuclear Explosives

Date: February 1964
Creator: Vortman, Luke J.
Description: Partial abstract: "This report is based: (1) on information developed in earlier high explosive experiments which determined the optimum spacing and burial depth of charges in a row to produce a channel uniformly wide and deep, and (2) on the Sedan and Danny Boy experiments, which provided data on dimensions of nuclear craters in both soil and basalt rock. This information has been combined with the 1947 route surveys of the Panama Canal company, and estimates have been made not only of the number and yield of nuclear explosives required to excavate a Transisthmian canal with nuclear explosives, but also of the cost of the explosives and the cost of their replacement."

Mineral Resources of the Honeycomb Buttes Wilderness Study Area, Fremont and Sweetwater Counties, Wyoming

Mineral Resources of the Honeycomb Buttes Wilderness Study Area, Fremont and Sweetwater Counties, Wyoming

Date: 1987
Creator: Patterson, Charles G.; Kulik, D. M.; Loen, Jeffrey S.; Koesterer, M. E. & Scott, David C.
Description: From summary: This report includes field investigations to evaluate the mineral resource potential of the Honeycomb Buttes were conducted during the summer of 1984. Geologic mapping, geochemical sampling, geophysical surveys, stratigraphic and sedimentological studies, and surveys of prospects delineated areas of very low grade placer gold deposits in terrace gravels and low and moderate resource potential for additional similar undiscovered placer gold deposits, low and moderate resource potential for small uranium deposits, moderate resource potential for accumulation of oil and gas, and low resource potential for coal and oil shale.

Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

Date: June 1960
Creator: Repenning, Charles Albert
Description: From introduction: This report describes the geology of the area only to the extent necessary for preliminary evaluation of the possibilities for the disposal of liquid radioactive waste by injection through deep wells. Their value will increase with development of extensive commercial production of atomic power and attendant creation of radioactive waste from the processing of spent fuel elements. The disposal of liquid waste in deep reservoirs is only one of several possibilities that must be considered.

Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Estimating Safety Probabilities from Fallout Forecasts for Nevada Test Site

Date: July 1, 1960
Creator: Reed, Jack W.
Description: Abstract: "Available data on wind persistence and wind forecasting capability have been applied in estimating the probability of a fallout pattern shifting from an uninhabited safe sector into a populated region. Safety probability is computed from win variability, forecasting accuracy, initial height and particle size of radioactivity landing at a point in the predicted fallout pattern, predicted wind speed, length of forecast period, and safe-sector angular width."

Experimental Pressure Distributions and Force Coefficients on Block Forms for Varying Mach Number, Reynolds Number, and Yaw Angle

Experimental Pressure Distributions and Force Coefficients on Block Forms for Varying Mach Number, Reynolds Number, and Yaw Angle

Date: January 1959
Creator: Hankins, Dorris M.
Description: Abstact: "Wind tunnel tests were performed to determine pressure distributions and normal force coefficients on three block forms on mounting planes. The dimension ratios of the blocks were 1:1:1, 1:1:2, and 1:1:4. Results are given for variation in Mach number from 0.066 to 0.8, in Reynolds number from 0.28 x 10(exp 6) to 4 x 10(exp 6), and in yaw angle from 0 to 90 degrees. Results show a Reynolds number independence over the range examined. Windward face force coefficients for a given block form are approximately proportional to the ratio of impact to dynamic pressure. Pressure distribution and resultant coefficients are affected by mounting planes."

An Exploding Wire as a Fuse for the LASL Capacitor Bank--Zeus

An Exploding Wire as a Fuse for the LASL Capacitor Bank--Zeus

Date: June 4, 1959
Creator: Cnare, Eugene C.
Description: Abstract: "An exploding copper wire, one millimeter in diameter, 30 centimeters long, has been developed as a fuse component for a Los Alamos capacitor energy source to be employed in controlled thermonuclear research studies. The fuse allows the passage of the high normal duty "action" (13,700 ampere-coulombs per capacitor) at a 20-second repetition rate. However, it interrupts the circuit to a shorted capacitor in 12 microseconds, thereby protecting the faulted capacitor from explosive energy consumption. The initial phase of the development included observations of various metals (copper, silver, iron, and nickel) as well as various configurations (straight wires, helixes, foils, and tubes). Direct scaling of previous small exploding wire studies at Sandia Corporation was demonstrated with scaling factors up to 700,000."

Date: October 1959
Creator: Johnson, Arlo F.
Description: Abstract: "The excellent agreement between measured boundary layer thickness and thickness calculated by Sivells and Payne recommends their method for calculating turbulent boundary layer growth in axisymmetric hypersonic nozzles. It was thought worthwhile to adapt their approach to the laminar boundary layer. This analysis, along with a limited amount of corroborating data, is presented herein."
