FIELD INVESTIGATIONS NATIONWIDE REVEAL THE PRESENCE OF NON-AQUEOUS PHASE LIQUIDS IN THE SUBSURFACE. OILY FUELS HAVE BEEN RELEASED TO THE SUBSURFACE BY LEAKY TANKS, WHILE AT OTHER SITES, CONTAMINATION HAS RESULTED FROM CHEMICAL SPILLS AND IMPROPER WASTE DISPOSAL PRACTICES. DUE TO THE COMPLEXITIES OF MULTIPHASE FLOW AND TRANSPORT PROCESSES, RESEARCHERS HAVE ONLY RECENTLY BEGUN TO DEVELOP SIMULATION ...

CERAMICS ARE ATTRACTIVE AS PROTECTIVE BARRIER COATINGS. THIS IS ESPECIALLY TRUE FOR SOL-GEL-DERIVED COATINGS BECAUSE OF THEIR RELATIVELY MILD PROCESSING CONDITIONS. A FUNDAMENTAL PROBLEM IN ALL CERAMIC COATING APPLICATIONS IS ADHERENCE OF THE COATING TO THE SUBSTRATE. CHEMICAL INERTNESS OF THE INVOLVED MATERIALS, MISMATCH IN THERMAL EXPANSION COEFFICIENTS, AND CERAMIC BRITTLE BEHAVIOR ARE ALL CONT ...

THERE ARE MULTIPLE APPLICATIONS FOR COMPACT PARTICLE ACCELERATORS, ESPECIALLY HIGH ENERGY [TENS OF MEV] AND HIGH CURRENT [KA] OUTPUT. GRADIENTS OF 10 TO 20 MV/M ARE POSSIBLE ONLY WITH RF ACCELERATORS. EXISTING LINEAR INDUCTION ACCELERATORS (LIAS) DO NOT OPERATE AT OVER 1 MV/M. RESEARCHERS ARE DEVELOPING AN INSULATOR TECHNOLOGY TO SUPPRESS AND ENHANCE VACUUM SURFACE FLASHOVER. THE TECHNOLOGY OPERAT ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...
