QUENCHING OF ROOM-TEMPERATURE PHOSPHORESCENCE OF LUMINESCENT COMPOUNDS IMMOBILIZED ON OR IN SUITABLE THIN- FILM MATRICES IS PLANNED AS A METHOD FOR MEASURING RELATIVE HUMIDITY. COMBINED WITH FIBER OPTICS TECHNOLOGY THIS APPROACH APPEARS TO HAVE THE CAPABILTY OF MEASURING RELATIVE HUMIDITY. COMBINED WITH FIBER OPTICS TECHNOLOGY THIS APPROACH APPEARS TO HAVE THE CAPABILITY OF MEASURING AND/OR MONITO ...

THE USE OF LASERS AS A SURGICAL MODALITY HAS BEEN ESTABLISHED IN RECENT YEARS. LASERS OF VARIOUS WAVELENGTHS ARE SUITED FOR DIFFERENT SPECIFIC SURGICAL FUNCTIONS. CO2 (10.6 ) RADIATION HAS SMALL PENETRATION DEPTHS IN TISSUES. THIS LEADS TO HIGH SURFACE TEMPERATURES WHICH ARE DESIRABLE FOR TISSUE INCISION THROUGH EVAPORATION. ND:YAG LASERS (1.06 ) PROVIDE VOLUMETRIC TISSUE HEATING WHICH IS EFFECTIV ...

THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A PULSED MID-IR LASER IN THE 3.5 TO 4.1 MICROMETER ATMOSPHERIC TRANSMISSION WINDOW. SUCH SPECTRAL SOURCE IS RELEVANT TO A VARIETY OF TACTICAL APPLICATIONS. THE DF CHEMICAL LASER HAS BEEN THE CHOICE, BUT SUFFERS FROM WASTE FUEL MANAGEMENT PROBLEMS. NO OTHER EFFICIENT DIRECT LASING SOURCE IS AVAILABLE. TO OBTAIN SUCH A SOURCE, WE PROPOSE THE USE O ...

THE GOAL OF THE PROPOSED RESEARCH IS TO PROVIDE THE NUCLEAR MEDICINE COMMUNITY WITH A COMPACT LINEAR ACCELERATOR (LINAC) FOR THE PRODUCTION OF THE PRINCIPAL SHORT-LIVED RADIOISOTOPES USED IN POSITRON EMISSION TOMOGRAPHY. THE DESIGN OF THIS LINAC WILL BE BASED ON EXCITING NEW TECHNOLOGIES DEVELOPED FOR A PION-GENERATING LINAC (PIGMI) AT THE LOS ALAMOS NATIONAL LABORATORY AND FUNDED BY THE NATIONAL ...

THE PURPOSE OF THE PROPOSED PROJECT IS TO PROVIDE A PROOF OFCONCEPT EVALUATION OF AN INSTRUMENT CAPABLE OF MEASURING NO,02, AND SO2 USING UV ABSORPTION AND A PHOTODIODE ARRAY SPECTROPHOTOMETER. IF SUCCESSFUL, THIS INSTRUMENT WOULD SATISFY ALL THE REQUIREMENTS OF A CONTINUOUS EMISSION MONITORING SYSTEM REQUIRED BY THE ENVIRONMENTAL PROTECTION AGENCY. SINCE ALL THREE GASES WOULD BE MEASURED WITH A S ...

A MANIPULATOR DESIGN IS PROPOSED WHICH USES ADVANCED MATERIALS AND CONTROL TECHNIQUES TO ACHIEVE PERFORMANCE FAR SUPERIOR TO THAT OF CONVENTIONAL MANIPULATORS. PRELIMINARY STUDIES INDICATE THAT A MANIPULATOR CAN BE DESIGNED WITH A USEFUL LOAD CAPACITY OF 100 KILOGRAMS, A USEFUL REACH OF 2.5 METERS, AND END-EFFECTOR SPEED OF AT LEAST 5 METERS/SEC, AND A WEIGHT OF LESS THAN 500 KILOGRAMS. THE DESIGN ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP TRANSITION RADIATORS WITH HIGH AVERAGE PHOTON FLUX AND TO USE THEM AS X-RAY SOURCES FOR SCIENTIFIC AND TECHNOLOGICAL RESEARCH. IN PARTICULAR, THE COMPANY WILL STUDY THE USE OF THESE SOURCES FOR X-RAY LITHOGRAPHY FOR THE PRO- DUCTION OF INTEGRATED CIRCUITS. USING A NEWLY-DEVEL- OPED HIGH-AVERAGE-CURRENT, 50 MEV ACCELERATOR, THE TOTAL PHOTON FLUX FROM SEVE ...

A CONSIDERABLE AMOUNT OF R & D WORK HAS BEEN DONE FOR THE WANKEL ROTARY ENGINE APPLICATION TO AUTOMOBILES, PLANES, ETC. RESULTING IN SIGNIFICANT PROGRESS. THE PERFORMANCE, RELIABILITY AND DURABILITY THAT THE WANKEL HAS DEMONSTRATED, HOWEVER, FALLS SHORT OF THE POPULAR DIESEL ENGINE. THE ADIABATIC, TURBOCOMPOUND CONCEPT THAT HAS BEEN DEMONSTRATED FOR THE DIESEL IS THOUGHT TO BE MORE BENEFICIAL TO T ...

AGE DISCRIMINATION IN EMPLOYMENT HAS CONSIDERABLY LESSENED THE ECONOMIC AND EMPLOYMENT OPPORTUNITIES OF MIDDLE AGED ANDOLDER JOB SEEKERS. INADEQUATE JOB TRAINING REPRESENTS A BARRIER CONFRONTING THE OLDER JOB SEEKER AND IS A MAJOR ASPECT OF AGE DISCRIMINATION. THIS IS ESPECIALLY A PROBLEM TODAY GIVEN CHANGES IN JOB DEMANDS (A SHIFT IN EMPHASIS FROMPHYSICAL SKILLS TO INFORMATION PROCESSING SKILLS) ...

THE OBJECTIVE OF THIS EFFORT IS TO DEVELOP A MANUFACTURING PROCESS AND SAMPLE HARDWARE FOR A LIGHTWEIGHT, TOUGH COMPOSITE CLASS 70 TRIARCH BRIDGE DECK. CONTINUOUS FIBER REINFORCED THERMOPLASTIC COMPOSITES (TPC) ARE WELL SUITED TO THIS APPLICATION BECAUSE THEY OFFER REDUCED WEIGHT, IMPROVED IMPACT DAMAGE TOLERANCE, LOW CORROSION POTENTIAL, AND ARE SUITED FOR HIGH VOLUME MANUFACTURING METHODS. AFTER ...
