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 ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

NO METHOD CURRENTLY EXISTS TO DIRECTLY RELATE DEVICE OUTPUT TO THE KNOWN INPUT NECESSARY FOR THE RELIABLE INITIATION OF THE NEXT DEVICE IN AN EXPLOSIVE TRAIN. THE OBJECT OF THIS EFFORT IS TO DEVELOP A TECHNIQUE TO PROVIDE AN ELECTRONIC SYSTEM TO MEASURE THE OUTPUTS OF EXPLOSIVE DEVICES. THE PHASE I EFFORT WILL DEVELOP A TECHNIQUE TO ACCOMPLISH THIS OBJECTIVE. WE PROPOSE TO UTILIZE NEW PIEZO FILM T ...

A growing number of fire fighters are suffering third degree burns; this has led to questions about the adequacy of thermal protective performance (TPP) measurements for protective clothing. A new heat flux sensor, whose response approximates that of skin, will be developed to provide better measurements of heat transfer in TPP tests. This sensor will be used with nonlinear parameter estimation an ...

THIS OBJECTIVE OF THIS PROJECT IS TO DEVELOP AND BUILD A PROTOTYPE OF A DC TO DC VOLTAGE CONVERTER TO BE USED IN ELECTRONIC FOIL INITIATOR APPLICATIONS. THE DC TO DC CONVERTER WILL WORK AT 80% EFFICIENCY USING CURRENT MODE CHARGING. THE WORKING VOLTAGE WILL BE 2.5 KV WITH AN OVERALL POWER DENSITY OF 25 WATTS PER CUBIC INCH. THE DC TO DC REQUIRES AN DYNAMIC ENVIRONMENTAL INPUT FOR CHARGING. THIS UN ...

THE USMC NIGHT TARGETING SYSTEM (NTS), DESIGNED FOR INSTALLATION IN THE AH-1 ATTACK HELICOPTER BY 1994, IS REPRESENTATIVE OF THE MULTI-SENSOR SYSTEMS REQUIRING COMPREHENSIVE TRAINING FOR SKILLS OF AIR AND GROUND CREWS. DCS WILL CONDUCT A DETAILED STUDY OF TRAINING REQUIREMENTS FOR OPERATOR AND MAINTENANCE PERSONNEL IMPOSED BY THE INCORPORATION OF THE NIGHT TARGETING SYSTEM (NTS) IN THE AH-1W AIRCR ...
