AUTOMATED BLOOD CELL ANALYSIS IS A ROUTINE FUNCTION IN THE CLINICAL HEMATOLOGY LABORATORY. HOWEVER, THE FLOW CYTOMETRIC INSTRUMENTATION PERFORMING THESE TESTS MAY HAVE FUNDAMENTAL LIMITATIONS REGARDING MEASUREMENT OF RED BLOOD CELL VOLUME, RED BLOOD CELL HEMOGLOBIN CONCENTRATION, AND ACCURATE CLASSIFICATION OF WHITE BLOOD CELL SUBPOPULATIONS. THE "HIGH-END" INSTRUMENTS HAVE BECOME VERY COMPLEX AND ...

BETWEEN COCHLEAR IMPLANTS AND QUADRI/PARAPLEGICS, THERE ARE APPROXIMATELY 700,000 PERSONS IN THE U. S. WHO WOULD BENEFIT FROM PROSTHETICS UTILIZING NEURAL OR NEUROMUSCULAR STIMULATION. SUCH SYSTEMS REQUIRE IMPLANTABLE, HIGH-SPEED, BI-DIRECTIONAL, TRANSCUTANEOUS DATA TRANSMISSION IMMUNE TO VARIATIONS IN THE LOCAL ENVIRONMENT. TO DATE, DATA LINKS INDEVELOPMENT ARE NOT PROJECTED TO MEET THE COMBINED ...

Endoscopic exploration of the utero-fallopian region is useful and may become a more general observational modality if a viewing instrument can be build with a front end that is disposable and inexpensive, has a small diameter with potential for transcervical introduction without anesthesia, and can provide high image resolution. The goal is the development of a falloposcope with high resolution i ...

A NEW TECHNIQUE IS PROPOSED FOR THE PREPARATION OF METAL-SUPPORTED METAL (MSM) CATALYSTS. THE KEY FEATURE OF THIS TECHNIQUE INVOLVES THE PREPARATION OF A THIN LAYER OF POROUS METAL ON TOP OF A METAL SUBSTRATE SUCH THAT THE POROUS METAL SURFACE IS AN INTEGRAL PART OF THE METAL SUPPORT. SUBSEQUENT INTEGRATION OF PT AND RH ON THE POROUS METAL SURFACE WILL PRODUCE THE MSM CATALYST. THIS CATALYST IS US ...

U.S. production of Halons will decrease from 28 million lbs in 1988 to zero in 1995 to meet the U.S. commitments to the Montreal Protocol. A major use of Halon 1301 is as a fire suppression flooding agent. The use of fine water mists from two-fluid atomizing nozzles is proposed as a replacement for Halon 1301 fire suppression systems, especially for Class B fuel fires. The optimum droplet size and ...

THE EMISSION OF HALOGEN CONTAINING POLLUTANTS FROM A VARIETY OF POWER GENERATING, WASTE PROCESSING, CHEMICAL PRODUCTION, AND SOLVENT USING INDUSTRIES IS AN ENVIRONMENTAL CONCERN OF MAJOR SIGNIFICANCE. INORGANIC HALOGEN SPECIES, INCLUDING HYDROGEN CHLORIDE AND HYDROGEN FLUORIDE, REPRESENT MAJOR POTENTIAL HEALTH THREATS TO BOTH HUMAN, ANIMAL, AND PLANT COMMUNITIES. ORGANIC HALOGENATED COMPOUNDS (HOC ...

DOE IS DEVELOPING A NUMBER OF ADVANCED COAL CONVERSION PROCESSES THAT OPERATE AT HIGH TEMPERATURES AND PRESSURES. THE COAL THAT IS CONVERTED IN THESE PROCESSES PRODUCES A VARIETY OF CONTAMINANTS. THESE CONTAMINANTS NEED TO BE REMOVED FROM THE HOTGAS STREAM IN ORDER FOR THEPROCESS TO OPERATE AT MAXIMUM EFFICIENCY. VOLATILE METALS CONSTITUTE A FAMILY OF COMPOUNDS FOUND IN THESE GAS STREAMS THAT WILL ...
