High-Explosive Ditching from Linear Charges (open access)

High-Explosive Ditching from Linear Charges

Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data."

Salton Sea Meteorological Instrumentation Test Series, Salton Sea, California, Conducted in September 1959 (open access)

Salton Sea Meteorological Instrumentation Test Series, Salton Sea, California, Conducted in September 1959

Abstract: "This report discusses tests conducted to determine the accuracy of meteorological equipment which is used to gather upper air data. Equipment tested was the GMD-2, SMD-1A, GMD-1B, and the WBRT-57. A four-station phototheodolite network was used as a standard for point-in-space determinations."

High Explosive Crater Studies: Tuff (open access)

High Explosive Crater Studies: Tuff

Abstract: "Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions."

High Explosive Crater Studies: Desert Alluvium (open access)

High Explosive Crater Studies: Desert Alluvium

From abstract: Crater dimensions have been determined for 23 explosions of 256-pound spherical TNT charges buried in desert alluvium. As opposed to previous work covering depths of burst as great as 6 feet, the work presented in this report extends knowledge of apparent crater radius and depth to depths of burst as great as 30 feet.

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains (open access)

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

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 Pulse Ammeter (open access)

A Pulse Ammeter

A quantizing pulse ammeter has been designed which brackets an input pulse current peak between two preset current levels. These levels are easily selected by calibration circuits contained on the chassis. Readout is presented in the form of a Nixie visual display as well as an output which is suitable for automatic data recording.
