Faceting of high angle grain boundaries in the coincidence lattice

Description: Faceting of high angle grain boundaries in SIGMA = 3 and SIGMA = 5 coincidence lattices of the fcc structure was studied using thinfilm bicrystal specimens of controlled geometry. A number of relatively high index boundaries in the coincidence lattices (containing relatively low planar densities of coincidence sites) was found to break up into low energy facets corresponding to low index planes of the coincidence lattices (containing high densities of coincidence lattice sites). These results a… more

High-resolution optical imaging on thermoplastic film

Description: Experimental details of a novel method for recording optical images is presented. In this method, a photoconductive layer arranges electric charges according to the optical image projected onto it. The differential electric fields thus produced, squeeze a thermoplastic layer into ridges that constitute the final image. The interference of two laser beams (0.83 mu m) that formed an optical image of l000 cycles/mm was clearly and accurately recorded. The spatial frequency response differs from th… more

Electrical power generation: comparative risks and benefits. Final report, August 6, 1973--August 10, 1973. A one-week workshop for high school science teachers

Description: A live-in type workshop available for academic credit covering basic nuclear power generation and the tradeoffs and problems that exist between nuclear power and alternative means to generate electricity was held for 37 high- school teachers at the Madison campus for the University of Wisconsin. Significant improvements over last year's program included the distribution of a large amount of information and the distribution of two minicourse outlines on the subject of power and the environment e… more

Cost and feasibility of stimulating tight gas reservoirs with chemical explosives

Description: Long, continuous, cylindrical charges of high explosives are considered as alternatives to nuclear explosives or massive hydraulic fracturing for the stimulation of gas production in tight gas formations. The calculational method was that used previously for nuclear stimulation; it was verified by comparison of the calculated and observed gas production from Rulison. The calculations indicate that charges of high explosives 24 inches in diameter and 2000 feet in length (the height assumed for t… more

Measurements of cosmic radiation dose in subsonic commercial aircraft compared to the city-pair dose calculation

Description: The radiation dose received by passengers during flight on conventional jet aircraft was determined as a function of exposure to cosmic radiation, solar radiation, flight time, and flight path. The dosimetric measurements were made with thermoluminescent dosimeters (TLD's) and with emulsions of three types sealed in plastic packets. These packets were sent by air mail back and forth from Berkeley, California to five cities and a dose sufficiently above background for a satisfactory measurement … more
