THE HUMAN GROWTH FACTOR INTERLEUKIN 7(IL-7) APPEARS TO BE ANESSENTIAL FACTOR FOR EARLY LYMPHOID B- AND T-CELL DEVELOPMENT. THE LONG-TERM OBJECTIVE IS TO TEST ITS EFFICACY BOTH IN VITRO AND IN VIVO IN IMPROVING BONE MARROW TRANSPLANTATION AND GENE TRANSFER PROTOCOLS. NATURAL IL-7 WAS RECENTLY CLONED AND EXPRESSED IN COS-7 CELLS BUT IS NOT COMMERCIALLY AVAILABLE. THIS PHASE I PROJECT SPECIFICALLY AI ...

QUANTUM CONFINED STRUCTURES SUCH AS SUPERLATTICES AND QUANTUM "WIRES" AND "DOTS" ARE THE FOCUS OF MUCH CURRENT RESEARCH BOTH FOR NEW PHYSICS AND NEW TECHNOLOGY. THESE APPROACHES PERTURB THE ELECTRONIC STATES OF THE SOLID IN AN ESSENTIAL WAY. WEAK PERTURBATIONS CAN BE ACHIEVED BY USE OF SURFACE GRATING STRUCTURES. SUCH STRUCTURES USING CURRENT TECHNOLOGY ARE LIMITED TO GRATING PERIODS OF 100 NM OR ...

THE PROPOSED MIRROR WILL CONVERT THE LINE-SHAPED, GAUSSIAN CROSS SECTION X-RAY OUTPUT PRODUCED BY A SYNCHROTRON BENDINGMAGNET INTO A NEARLY SQUARE, UNIFORMLY DISTRIBUTED PATCH, IDEAL FOR PROXIMITY LITHOGRAPHY. INITIAL RAYTRACING AND CALCULATIONS INDICATE THAT THE MIRRORSHOULD BE 50 TO 100% MORE EFFICIENT THAN THE SYSTEMS CURRENTLY USED TO SPREAD AND HOMOGENIZE BENDING MAGNET RADIATION, AND WILL HA ...

WE PROPOSE TO DEVELOP A SYSTEM FOR HIGH RESOLUTION ( 0.05 MU) INSPECTION OF DEFECTS ON RELATIVELY LARGE AREA INTEGRATED CIRCUITS (IC). THE SYSTEM WOULD COMBINE A HIGH RESOLUTION HOLOGRAM (INTERFEROGRAM) OF AN IC WITH A REFLECTION X-RAY MICROSCOPE(1). THE X-RAY HOLOGRAM WOULD ENABLE THE FAST LOCALIZATION OF DEFECTS, AND THE X-RAYMICROSCOPE WOULD PROVIDE A HIGH RESOLUTION IMAGE OF ANY DEFECTS. INITI ...

A SOFT X-RAY LASER AT PRINCETON UNIVERSITY (18.2 NM WAVELENGTH, 10-30 NSEC PULSES) CAN PRODUCE IMAGES OF LIVE CELLS IN WATER ON RESIST. IN COLLABORATION WITH PRINCETON UNIVERSITY, PRINCETON X-RAY LASER, INC., IS DEVELOPING LASERS WITH SHORTER WAVELENGTHS. THERE ARE REALISTIC PROSPECTS FOR OBTAINING LASER ACTION BELOW 10 NM, DOWN TO 1 NM. VIABLE BIOMEDICAL USE REQUIRES METHODS TO RETRIEVE INFORMATI ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A WRITTEN SET OF PLANNING PROTOCOLS, STATISTICAL ALGORITHMS, AND COMPUTER SOFTWARE THAT WILL ASSIST RURAL HOSPITALS AND THEIR COMMUNITIES IN EVALUATING THE EFFICACY AND FINANCIAL CONDITIONS OF THEIR HOSPITALS AND HEALTH-CARE DELIVERY SYSTEMS IN PLANNING FOR CHANGE. THE PROTOCOLS ARE TO BE DESIGNED AS PLANNING STEPS THAT USE HISTORICAL DATA ON HOSPITAL O ...

NANOMETER-SCALE AGGREGATES OF ORDER 10 TO 100 ATOMS, KNOWN AS CLUSTERS, HAVE GENERATED A GREAT DEAL OF INTEREST IN RECENT YEARS DUE TO THEIR POTENTIAL APPLICATIONS AS CATALYSTS, OPTICAL MATERIALS AND ELECTRONIC MATERIALS. STABLE CLUSTERS OF CARBON HAVE BEEN OBSERVED AND A UNIQUE SPHERICAL STRUCTURE SIMILAR TO THAT OF A SOCCER BALL HAS BEEN PROPOSED FOR THEM. CARBON CLUSTERS ARE GIVEN THE NAME FULL ...

DEMONSTRATION TESTING OF ADVANCED PROCESS EQUIPMENT IS EXPECTED TO CONFIRM THE FEASIBILITY OF THE INTEGRAL FAST REACTOR (IFR) FUEL CYCLE PROCESS AT THE HOT FUEL EXAMINATION FACILITY - SOUTH (HFEF-S) ON THE ARGONNE-WEST SITE IN IDAHO. TEST RESULTS WILL BE INCORPORATED INTO THE DESIGN OF A COMMERCIAL IFR FUEL CYCLE FACILITY. THIS PROJECT CONTRIBUTES TO DEVELOPMENT OF A CONCEPTUAL DESIGN FOR AN ADVAN ...
