RECENT TESTING OF AIR-SPARGED HYDROCYCLONE (ASH) FLOTATION TECHNOLOGY FOR FINE COAL CLEANING AT THE EPRI/CODC TEST FACILITY HAS SHOWN THAT THE ASH SYSTEM HAS GREAT POTENTIAL FOR UTILIZATION IN THE COAL INDUSTRY. HOWEVER, EFFECTIVE UTILIZATION OF THIS TECHNOLOGY RELIES ON OPTIMUM CONTROL ANDCONTINUAL ADJUSTMENT OF MANIPULATED VARIABLES WITH RESPECT TO FLOTATION PERFORMANCE SINCE THE RETENTION TIME ...

ALTHOUGH SPECIALLY DESIGNED END-EFFECTORS HAVE PROVIDED PRESENT DAY ROBOTS AND TELEOPERATOR SYSTEMS WITH THE ABILITY TO DO MANY INTRICATE TASKS, TRUE MANIPULATOR DEXTERITY WILL ONLY COME THROUGH THE USE OF MULTI-FINGERED ANTHROPOMORPHIC MECHANICAL HANDS. STABLE GRASPING OF IRREGULAR OBJECTS, OBJECT RECOGNITION, PRECISION ASSEMBLY, AND PERFORMANCE OF MANY INTRICATE TASKS NOW CONFINED TO HUMANS WILL ...

THE LONG-TERM OBJECTIVES OF THIS PROJECT ARE THE METHODOLOGY DEVELOPMENT AND MANUFACTURING OF ANTITHROMBOGENIC SURFACES CONTAINING POLYETHYLENE OXIDE (PEO)-TETHERED BIOACTIVE COMPOUNDS THAT COUNTERACT OR INHIBIT THE MAJOR THROMBOGENIC EFFECTS KNOWN TO OCCUR WHEN A SURFACE IS EXPOSED TO BLOOD. THE SPECIFIC AIMS OF PHASE I ARE TO: (1) PRODUCE AND CHARACTERIZE IN DETAIL HEPARIN-ONLY AND UROKINASE-ONL ...

THE LONG-TERM OBJECTIVE OF THIS PROJECT IS THE DEVELOPMENT OF NEW REAGENTS AND METHODOLOGIES FOR COUPLING POLYMERS AND ANTITHROMBOGENIC COMPOUNDS TO POLYMER SURFACES IN MULTISTEP SEQUENCES UNDER AQUEOUS CONDITIONS. THE SPECIFIC AIMS OF THE PHASE I RESEARCH ARE: (1) SYNTHESIS, CHARACTERIZATION, AND STABILITY STUDIES OF POLYETHYLENE OXIDE (PEO) SPACERS MODIFIED WITH NOVEL, WATER-STABLE END GROUPS; ( ...

STRIATAL TRANSPLANTATION OF NEUROTRANSMITTER CELLS, IMMUNOISOLATED WITHIN A PERMSELECTIVE POLYMER MEMBRANE CAPSULE, REPRESENTS A NOVEL APPROACH TO THE TREATMENT OF PARKINSON'S DISEASE. THE TECHNIQUE HAS HAD PROMISING RESULTS IN SEVERAL RODENT MODELS, AND PRIMATE STUDIES ARE UNDERWAY. THE OVERALL OBJECTIVE OF THIS RESEARCH IS TO COMPLETE THE DEVELOPMENTS NECESSARY FOR WIDESPREAD MEDICAL ACCEPTANCE ...

THE LONG-TERM OBJECTIVE OF THIS RESEARCH IS THE DEVELOPMENT AND INTRODUCTION TO MEDICAL PRACTICE OF AN EFFECTIVE BIOCOMPATIBLE IMPLANTABLE HYBRID ARTIFICIAL ENDOCRINE PANCREAS THAT IS CAPABLE OF SIGNIFICANT IMPROVEMENT IN THE THERAPY OF INSULIN-DEPENDENT DIABETES. THE SPECIFIC AIM OF THIS PROJECT IS TO EXTEND AND MODIFY A PROCESS FOR CELLULAR ENCAPSULATION TO THE ISLETS OF LANGERHANS, USING A CO-E ...

RFLP ANALYSIS HAS BEEN SHOWN TO HAVE TREMENDOUS IMPLICATIONSFOR BOTH THE DIAGNOSIS OF GENETIC TENDENCIES FOR HUMAN DISEASE AND FOR APPLICATIONS TO PLANT AND ANIMAL IMPROVEMENT; UNFORTUNATELY, THE DEMANDS FOR ITS USE HAVE OUTSTRIPPED THE CAPACITY OF WHAT IS PRIMARILY A RESEARCH TECHNOLOGY. A REPLACEMENT TECHNOLOGY IS DESIRED THAT IS FASTER, CHEAPER, AND WITH A HIGHER THROUGHPUT BUT, AT THE SAME TIM ...

CONTRACTOR WILL EXAMINE THE FEASIBILITY OF UTILIZING ITS PIEZOCERAMIC CHIPS AS ACTUATORS FOR VARIABLE TWIST PROPELLERS IN UAV APPLICATIONS. THESE ACTUATORS WILL BE UTILIZED TO OPTIMIZE THE TWIST OF RIBSTIFFENED ELASTOMERIC PROPELLER BLADES ON A BLADE-ELEMENT-BY-BLADEELEMENT BASIS SO THAT EACH SEGMENT OF THE BLADE IS OPTIMIZED WITH RESPECT TO HELICAL INFLOW ANGLE INDEPENDENTLY OF EACH OTHER SEGMENT ...
