A STEP TOWARD BEING NUMBER ONE IN MATHEMATICS AND SCIENCE EDUCATION BY THE YEAR 2000 (AMERICA 2000 GOAL) AND MAINTAINING REASONABLE SCHOOL BUDGETS CAN BE MADE BY INTRODUCING A LOW COST SYSTEM WHICH WILL BRING THE STATE-OF-THE-ART TECHNOLOGY INTO THE HIGH SCHOOL LABORATORY. THE PLANNED LABORATORY WORKSTATION ADDRESSES THIS NEED, BY TAKING THE STATE OF THE ART TOOLS AVAILABLE FOR RESEARCHERS AND INT ...

STATIONARY SOURCES IN THE U.S. EMIT ABOUT ONE MILLION KG OF MERCURY INTO THE ATMOSPHERE ANNUALLY. MAJOR SOURCES OF THESE EMISSONS ARE FOSIL FUEL COMBUSTIONFACILITIES ANE MUNICIPAL SOLID WASTE INCINERATORS. MUCH WORK IS BEING DONE BY DOE AND INDUSTRY TO CHARACTERIZE THESE EMISSIONS AND TO DEVELOP EFFECTIVE CONTROL MEASURES. CONTINUOUS EMISSIONS MONITORS (CEMS) FOR MERCURY WILL PLAY A SIGNIFCANT ROL ...

IMPROVED FABRIC FILTER PERFORMANCE FOR BOTH THE COLLECTION OF FINE PARTICULATE MATTER (PARTICLES LESS THAN 10 MICRONS) AND TOXIC METAL EMISSIONS FROM FLUEGASES IS IMPORTANT BECAUSE MOST OF THE TOXIC METALS ARE CONCENTRATED IN THIS SIZE RANGE, FINE PARTICLES ARE RESPIRABLE AND THEREFORE POSE A HEALTH RISK, AND FINE PARTICLES ARE EFFECTIVE LIGHT SCATTERERS AND LEAD TO HIGH OPACITY LEVELS. IT IS PLAN ...

REMOVAL OF MERCURY FROM CONTAMINATED WATERS IS A CONTINUING NEED FOR DOE'S SITE REMEDIATION EFFORTS. SOME SURFACE AND SUBSURFACE DISCHARGE OF CONTAMINATED WATER IS CONTINUING FROM MERCURY LOST TO THE ENVIRONMENT IN THE PAST. IN THE FUTURE, IT IS ANTICIPATED THAT MERCURY-CONTAMINATED STRUCTURES AND EQUIPMENT WILL BE SUBJECTED TO AQUEOUS WASHES, AND THAT THIS WATER WILL NEED TO BE TREATED BEFORE D ...

FOSSIL FUEL COMBUSTION SOURCES ARE THE LARGEST SINGLE CONTRIBUTOR OF ATMOSPHERIC MERCURY EMISSIONS AND THE SECOND LARGEST CONTRIBUTOR OF ATMOSPHERIC SELENIUM. OF ALL THE TRACE METALS CONTAINED IN COAL, MERCURY AND SELENIUM ARE OF GREATEST CONCERN SINCE THEY ARE THE MOST VOLATILE OF THE METALS, THEY ARE WIDESPREAD AND RELATIVELY TOOXIC, AND THEY DEPOSIT IN BIOSYSTEMS. IN ANTICIPATION OF FUTURE EM ...

THE MATERIALS CURRENTLY USED FOR RADIO FREQUENCY (RF) FEEDTHROUGH INSULATORS ARE INADEQUATE FOR FUTURE FUSION DEVICES SUCH AS THE INTERNATIONAL THERMONUCLEAR EXPERIMENTAL REACTOR (ITER). THESE MONOLITHIC CERAMICS WILL LOSE THEIR DIELECTRIC STRENGTH, AND SWELL IN THE NEUTRON FLUENCES EXPECTED IN ITER. THIS MAKES THEM EXTREMELY SUSCEPTIBLE TO BRITTLE FRACTURE, WHICH CAN LEAD TO CATASTROPHIC FAILURE ...

N/A

IT IS PLANNED TO RESEARCH AND DEVELOP A T-LAYER MAGNETOHYRODYNAMIC (MHD) ALTERNATING CURRENT (AC) GENERATOR. THE T-LAYER MHD CONCEPT IS AN INNOVATIVE IDEA FOR PRACTICAL APPLICATION TO MHD POWER. THE VIABILITY OF THE T-LAYER MHD POWER PROCESS HAS BEEN DEMONSTRATED IN THE LABORATORY. T-LAYER MHD IS A PROCESS WHEREIN A HIGH TEMPERATURE PLASMA LAYER, A T-LAYER, IS PRODUCED IN THE FLOW STREAM OF AN MHD ...

RESEARCH ON REMOTE SENSING DIAGNOSTICS WITH CAPABILITIES DESIGNED FOR THE UNIQUE MAGNETOHYDRODYNAMIC (MHD) ENVIRONMENT IS PLANNED. THE LARGE DIFFERENTIAL AND COMMON MODE VOLTAGES FOUND ON MHD FLOW TRAINS REQUIRE ISOLATION FROM OPERATING AND CONTROL SYSTEMS FOR HARDWARE AND PERSONNEL PROTECTION. FURTHERMORE, THE PROBLEMS OF MAGNETIC FIELD INTERFERENCE NEAR AND LIMITED ACCESS TO AN MHD GENERATOR POS ...
