THE TECHNICAL OBJECTIVES OF THIS PROPOSAL ARE ORIENTED TOWARD THE DEVELOPMENT OF SOIL SURFACTANT FLUSHING AND WASHING AS A LOW-COST, LOW-IMPACT, LOW-RISK, EFFECTIVE TECHNIQUE FOR THE REMOVAL AND ULTIMATE DESTRUCTION OF THE ORGANIC CONTAMINANTS IN SOIL. THESE OBJECTIVES ARE: DEMONSTRATION OF THE EFFECTIVENESS OF AN IONIC SURFACTANT SOLUTION AT CONCENTRATIONS ABOVE THE CRITICAL MICELLE CONCENTRATION ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

Not Available Q-Peak, Inc. proposes to develop a broadly tunable, 10-W-average-power IR source suitable for use as a DIAL system transmitter and based on the combination of a Nd-doped pulsed pump laser and optical parametric oscillators (OPO). The laser source, a compact, diode-pumped, 5-10 kHz pulse-repetition-rate, Q-switched Nd:YLF laser, will pump a tandem OPO system consisting of an angle-tu ...

Not Available This project is intended to develop a number of technologies and specific solutions to the problem of providing enhanced aircrew comfort particularly during extended missions and in ejection seats. This program will specifically address the issue of physical comfort associated with crew seating as opposed to the general cockpit environment. Efforts will be concentrated on the seat c ...

Not Available Currently, most semiconductor manufactures rely on electronic design automation (EDA) tools to design advanced microelectronics. However, their use for radiation-hardened (rad-hard) microelectronics is limited, since there is no available set of rad-hard design rules. Therefore, there is a need to develop computational models, starting from high-fidelity physics to circuit-level mod ...

Not Available Propellant technologies are of the most crucial to revolutionize aerospace propulsion in the next century. New propellants strive to make spacecraft safer, more operable and higher performing. Propellant technologies have the power to make space flight more affordable and deliver higher performance. Propellants for in space maneuvering need to be ignited to release its chemical ener ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...

THE MTIC INDIRECT STEAM REFORMING PROCESS OFFERS A COST EFFECTIVE ALTERNATIVE TO THE EXISTING WASTE-TO-ENERGY INCINERATION OF MUNICIPAL SLUDGE WASTE (MSW) OR REFUSE- DERIVED FUEL (RDF). THE PROCESS HAS THE POTENTIAL FOR RESOLVING MANY OF THE ENVIRONMENTAL ISSUES ASSOCIATED WITH INCINERATION, ESPECIALLY IN THE CONTROL OF CHLORINATED DIOXINS AND FURANS AS WELL AS EMISSIONS OF TOXIC METALS; PARTICULA ...
