Dynaflow, Inc., proposes the development of a novel jet-induced cavitation process for the removal of various pollutants¿including pesticides from wastewater discharge¿ that would be economical, readily applicable to both large- and small-scale systems, and that does not produce potentially hazardous by-products of chlorination and ozonation. Ultrasonically induced cavitation is known to be capa ...

The goal of this project is to develop a portable system for the real-time detection and quantification of adenovirus in wastewater. The system is based on a small, portable flow cytometer that was developed and is being marketed by Becton Dickinson Biosciences (BDB) under the trade name FACSCount¿ for use in selected medical and research applications. Unlike previous efforts to apply flow cytome ...

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 ...

Pulsed electric field (PEF) disinfection is becoming well known as a possible means for the control of microorganisms in fluids. Although this technique has been shown to be effective against a wide variety of microorganisms, its widespread application is impeded by the high specific energy input (kWh/L) required. Conversely, the proposed enhanced PEF process promises a significant reduction in th ...

Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

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 The purpose of the proposed research is to show that significant improvements in the performance of electrically tunable microwave devices can be obtained using a novel type of superlattice structures. The approach is based on recent work at Neocera showi

Not Available NASA SBIR Solicitation 98-1 emphasizes that ¿Advanced extravehicular activity (EVA) systems are necessary for the successful support of future human space missions.¿ Topic 09.05 recognizes that development of advanced EVA systems depends on ¿methods for..

Not Available Mod Works proposes to construct major airframe components using modern aluminum manufacturing process (MAM). The objective will be to reduce the cost of manufacturing while maintaining better surface quality. Major reduction in cost and labor requirement
