Gamma radiation spectrum produced by uranium 235 fission products, and effective absorption coefficients
Appropriate importance function and sampling scheme facilitates the application of the Monte Carlo method to problems involving the deep penetration of radiation.
Bremsstrahlung cross sections formulated with Dirac wave functions for screened and unscreened nuclear electrostatic fields
Polybenzimidazole synthesis, ablative screening tests, and char formation in PBI composites
Design, operation and construction of event recorder for monitoring heat ablation data
Linear Energy Transfer /LET/ spectrum of primary galactic radiation compared to flare produced radiation
Explore the source record for details and available documents.
Metallic coating directly sprayed on electronic modules provides simple and reliable lightweight protection against radio frequency interference. A plasma arc may be used. Aluminum and copper are the most effective metals.
FASTER computer program modified for tracking neutrons through reactor slabs penetrated by helical voided ducts
Rate of recovery after partial irradiation of mice and rats

Termination adapter replaces braid ring and ensures permanent attachment and grounding of sheath wires. The inner ferrule of the termination is slipped inside the exposed ends of the sheath wires and the outer ferrule is placed over the wires and crimped in place to secure the wires for grounding.
Energy transfer in reacting flow of pyrolysis products through char layer of nylon-phenolic resin charring ablator
Energy transfer in pyrolysis product flow through char layer of nylon phenolic resin ablator
Technique prevents silicon wafers from adhering to susceptor following silicon epitaxial deposition. Annular ring of refractory material goes around wafer during epitaxial deposit. Silicon is deposited on ring, susceptor, and portions of wafer. Ring breaks away from susceptor and wafer and no silicon undergrowth occurs.
Emission spectroscopy method for contamination monitoring of inert gas metal arc welding
Describing hot filament type Bayard-Alpert ionization gage with ion collector buried or removed from grid structure
Induction heating of metallurgical specimens to high temperatures in coil furnace
