IN 1985, 947 BILLION GALLONS OF WATER WERE CONTAMINATED WITH1.4 BILLION POUNDS OF CHMICAL REAGENTS IN FROTH FLOTATION SEPARATION OF INDUSTRIAL MINERALS IN THE UNITED STATES. IT IS ESTIMATED THAT THESE APPROXIMATE QUANTITIES WERE ALSO USED IN 1986 AND 1987. OF THIS TOTAL, APPROXIMATELY 42.2 MILLION GALLONS OF WATER WERE CONTAMINATED WITH 8.6 MILLION POUNDS OF CHEMICAL REAGENTS IN VERMICULITE FROTH ...

The purpose of the proposed project is to develop communication waveforms and network protocols that provide reliable, secure, survivable, communications in multifunction radio networks. The goal is to obtain increased spectral efficiency over current military radio networks through the use of new waveform designs that exploit recent developments in coding and modulation. Consideration is given to ...

A breakthrough in fiber laser technology has been achieved which opens the door to a whole class of efficient ultra-high brightness laser sources. These diode pumped devices have the potential to replace or augment almost all existing industrial, medical,and military laser applications. Kigre's new QX phosphate laser materials exhibit high strength, high gain, high durability and superior laser ...

This program will produce prototypes of aircraft wingtip treatments to reduce induced drag without increasing span of aircraft wings, and to reduce wind dynamic responses for improved ride. The advantages of conventional winglets have been demonstrated ontransport aircraft and business jets. Phase I of this effort demonstrated that even greater results can be obtained by modified winglets of new ...

DESCRIPTION (provided by applicant):Improvements in signal to noise ratio (SNR) and ease of use of magnetic resonance imaging (MRI) RF coils are needed to improve image quality and patient throughput. The goal of this Phase II project is to continue the development of novel rf coil topologies and rf balancing circuits that have demonstrated substantially improved technical performance, reduced co ...

Cryopreserved allogeneic human heart valves are presently the preferred aortic and pulmonary heart valve prostheses for pediatric patients, women of child-bearing age and non-drug compliant patients. Unfortunately, these valves often deteriorate in younger pediatric patients. The objective of this proposal is development of cryopreservation methods that cause less inter ...

Fresh osteochondral allografts have been proven clinically effective. However, the logistics of getting fresh, viable cartilage from donor to recipient requires the development of tissue banking methods. Conventional cryopreserved osteochondral grafts perform poorly in vivo and it is well established, in other tissue systems, that conventional cryopreservation often results in potentially damaging ...

The Phase I study demonstrated the feasibility that highly oriented PEEK and carbon-fiber-reinforced PEEK (CFR-PEEK) could be engineered as surface phosphonylated dental implants and these implants could be microtextured to enhance osseointegration. In the Phase I study, surface-phosphonylated and microtextured rods composed of solid-state oriented PEEK and CRF-PEEK were implanted transcortically ...
