SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

Significant similarities exist between DoD simulation applications and networked simulation games developed for entertainment. To date, however, there has been no compelling reason for commercial game developers to adopt DoD methods and standards. Interestingly, HLA compares favorably to current commercial solutions like Microsoft's DirectPlay. There is clear benefit to DoD if HLA is embraced b ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

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 ...

OptiMetrics, Inc. proposes to develop real-time monitoring and after action review tools specifically designed to function in advanced HLA simulation environments. The development approach will include: Tailoring tools to user requirements; A highly object-oriented design; A layered design to interface between our software and the external interfaces (e.g., HLA/RTI); A preference for COTS or GOT ...

CURRENT METAL CUTTING AND FINISHING OPERATIONS USE SKIMMING AND FILTRATION TO TRY TO SEPARATE WASTES FROM THEIR WATER BASED CUTTING FLUIDS. THE RESIDUAL LIQUID FROM THE FILTRATION CONSISTS OF ULTRAFINE METAL PARTICLES CONTAINING HAZARDOUS HEAVY METALS LIKE LEAD, ZINC, AND CADMIUM AND A TIGHTLY EMULSIFIED OIL-IN-WATER PHASE. THIS SLUDGE IS NOT AMENABLE TO FURTHER TREATMENT AND MUST BE HAULED OFF AS ...

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...
