Abstract:THIS RESEARCH PROJECT WILL DIRECTLY ADDRESS THE PROBLEM OF SWEEP IMPROVEMENT FOR ENHANCED OIL RECOVERY (EOR) PROCESSES. ONE OF THE MAJOR PROBLEMS IN CONDUCTING AN EFFICIENT EOR PROCESS IS THE CONTROL OF THE INJECTED FLUIDS. IN MOST FIELD APPLICATIONS OF MISCIBLE OR IMMISCIBLE SOLVENT DRIVES, SUCH AS… more
Abstract:THE OBJECTIVES OF THIS PHASE I WORK ARE TO: DETERMINE THE DESIGN REQUIREMENTS FOR AN EMBEDDED TRAINING SYSTEM. DETERMINE THE MATURITY OF INTELLIGENT TUTORING SYSTEMS FOR INCLUSION IN EMBEDDED TRAINING. DERIVE THE DESIGN FOR AN EMBEDDED TRAINING SYSTEM WHICH INTEGRATES WITH DECISION SUPPORT SYSTEMS… more
Abstract:Simulations and their measurement involve careful experiment design, data gathering and data analysis. The final results obtained from the data analysis only characterize the system behavrior for the range of input parameters covered. Although extrpolation can be used to obtain results for nearby… more
Abstract:Foods are dehydrated to make them more easily packaged and stored at room temperature. The removal of water reduces the opportunity for harmful chemical reactions. Dehydrated food powders and particles are also used in "liquid meals" for dental patients. However, dehydrated foods traditionally have… more
Abstract:SCIENTIFIC SOCIAL RESEARCH HAS COMPLETED DESIGN AND PROGRAMMING FOR A MICROCOMPUTER SOFTWARE SYSTEM PROVIDING PERSONAL SELF-ADMINISTERED RISK ASSESSMENT FOR HIV INFECTION. THE RISK ASSESSMENT IS BASED UPON AN ANONYMOUS INTERACTIVE INTERVIEW AND ANALYSIS PERFORMED BY A RULE-BASED EXPERT SYSTEM… more
Abstract:CYTOSKELETAL AND NUCLEAR MATRIX PROTEINS (NMPS) PLAY AN IMPORTANT ROLE IN THE BIO-CHEMICAL EVENTS INVOLVED IN DIFFERENTIATION AND TRANSFORMATION OF MAMMALIAN CELLS. CERTAIN OF THESE MARKERS, F/G-ACTIN AND BLADDER CANCER-RELATED NMPS, PROVIDE A UNIQUE MEANS FOR EARLY IDENTIFICATION OF BLADDER CANCER… more
Abstract:THE OIL INDUSTRY GENERATES LARGE VOLUMES OF DRILLING MUD WASTES THAT CONSTITUTE AN ENVIRONMENTAL PROBLEM. CURRENT PRACTICES INVOLVE RETAINING SUCH WASTES IN PITS, OR DISPOSING THEM BY REMOVING AND TRANSPORTING THEM TO ANOTHER LOCATION FOR TREATMENT. THE TECHNOLOGY STUDIED IN THIS PROJECT IS TREATING… more
Abstract:A HIGH CELL DENSITY FERMENTATION TECHNOLOGY IS PROPOSED FOR THE PRODUCTION OF MICROBIAL NERVE GAS DEGRADING ENZYMES. THIS TECHNOLOGY WILL RELY ON THE DEVELOPMENT OF AN ULTRA HIGH CELL DENSITY (GREATER THAN 100 G DRY WEIGHT CELLS/L) CONTINUOUS FERMENTATION FOR THE PRODUCTION OF MICROBIAL ENZYMES… more
Abstract:Current Techniques for identifying microbially influenced corrosion (MIC) involve a battery of chemical, electrochemical, metallurgical, and microbiological tests. The most common method for detection and evaluation of microbial activity employs plate or tube culture technique. These methods are… more
Abstract:TRICHLOROETHYLENE (TCE) IS A WIDESPREAD POLLUTANT AND IS REPORTED TO BE THE MOST FREQUENTLY ENCOUNTERED CONTAMINANT AT HAZARDOUS WASTE SITES. ALL PREVIOUS ATTEMPTS AT IN SITU BIOREMEDIATION HAVE USED A PROCESS WHERE METHANTROPHIC BACTERIA WERE STIMULATED BY THE SUBSURFACE DELIVERY OF AIR AND METHANE… more
Abstract:The purpose of this project is to develop an Artificial Intelligence (AI)-based Decision Support System (DSS) to support the preparation of the Program Objective Memorandum (POM) by TRADOC and other MACOMS. Phase I includes the development of an operational prototype which proves the worth of the… more
Abstract:IN A FEW YEARS, THE NATIONAL TRAINING CENTER (NTC) WILL HAVE NEW SIMULATION SYSTEMS AND UPGRADES TO RDMA AND RMCS. GIVEN EFFECTIVE AND EFFICIENT INTEGRATION, TEHSE SYSTEMS WILL INCREASE, SIGNIFICANTLY, THE AMOUNT AND FIDELITY OF DATA AVAILABLE TO THE TRAINING SNALYST. HOW EFFECTIVE THESE… more
Abstract:DENSE NON-AQUEOUS PHASE LIQUIDS (DNAPLS) ARE A CLASS OF ORGANIC COMPOUNDS COMMONLY FOUND AS GROUND WATER CONTAMINANTS; CHLORINATED SOLVENTS ARE AN IMPORTANT CLASS OF DNAPLS. MANY DNAPLS ARE CHARACTERIZED AS BEING IMMISCIBLE WITH AND HEAVIER THAN WATER. THESE CHARACTERISTICS COMBINE TO MAKE… more
Abstract:ECONOMICAL METHODS OF REMOVING AND/OR RECOVERING DISSOLVED ORGANICS OR METALS FROM WATER ARE NECESSARY FOR US INDUSTRIAL COMPETITIVENESS. ALSO, FIRMS SPECIALIZING IN HAZARDOUS WASTE DISPOSAL AND POLLUTION CONTROL WILL BE A MAJOR AREA OF INDUSTRIAL GROWTH IN THE US. MICELLAR-ENHANCED ULTRAFILTRATION… more
Abstract:CURRENT METHODS FOR ATTACHING END CLOSURES TO COMPOSITE MOTORCASES WITH FULL DIAMETER OPENINGS MOST FREQUENTLY UTILIZE MECHANIAL PIN OR KEY JOINTS REQUIRING ADDITIONAL WEIGHT AT THE JOINT AREA AND EXPENSIVE, TIME-CONSUMING MACHINING OPERATIONS. MORE EFFICIENT METHODS OF JOINING END CLOSURES TO… more
Abstract:THE PROGRAM WILL: 1) ASSIST TWO NATIVE YOUTH COUNCILS ESTABLISH AND SUCCESSFULLY OPERATE RECYCLING PROJECTS, 2) DEVELOP A TRAINING MANUAL FOR ORGANIZING AND OPERATING A RECYCLING PROJECT, AND TRAIN YOUTH IN ITS USE SO THEY CAN SUCCESSFULLY IMPLEMENT IT IN THEIR OWN COMMUNITIES, 3) TRAIN EARTH… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
