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 ...

THIS PROPOSAL IS TO INVESTIGATE THE FEASIBILITY OF UTILIZING LUMINESCENCE QUENCHING FOR MEASUREMENT OF RELATIVE HUMIDITY AT TEMPERATURES FOUND IN ARCTIC ENVIRONMENTS. IT IS BASED ON THE OBSERVATION THAT CERTAIN FLUORESCENT AND PHOSPHORESCENT COMPOUNDS, IMMOBILIZED ON SPECIFIC SUBSTRATES, SHOW A LUMINESCENT RESPONSE WHOSE INTENSITY IS PROPORTIONAL TO RELATIVE HUMIDITY OR THE PROPORTION OF WATER VAP ...

THE PRIMARY GOAL OF THIS RESEARCH IS THE DEVELOPMENT OF AN EASILY USABLE, NONTRAUMATIC APPARATUS FOR THE ACCURATE ASSESSMENT OF BODY VOLUME IN NORMAL AND LOW BIRTH WEIGHT INFANTS. A SECONDARY GOAL IS THE INCLUSION OF AN ASSESSMENTOF ENERGY EXPENDITURE INTO THE SAME APPARATUS. THE METHOD PROPOSED FOR THE VOLUME DETERMINATION INCORPORATES THE PROVEN METHOD OF FLUID DISPLACEMENT BUT UTILIZES A CONCEP ...

THE GOAL OF THIS PROJECT IS THE DEVELOPMENT OF A COMPACT, LOW-COST EXPIRED BREATH ANALYZER SUITABLE FOR DIAGNOSTIC APPLICATIONS IN HOSPITAL EMERGENCY ROOMS, CLINICS, AND FACTORY FIRST AID STATIONS. THE FIRST PHASE OF THIS STUDY WILL BE A DETERMINATION OF THE FEASIBILITY OF DEVELOPING A MICROVOLUME, LONG PATHLENGTH INFRARED GAS CELL BASED ON OPTICAL WAVEGUIDE PRINCIPLES. PHASE II WILL CONSIST OF TH ...

THE GOAL OF THIS RESEARCH IS TO DEVISE AUTOMATED METHODS OF ANALYZING THE AUDITORY BRAINSTEM RESPONSE (ABR) WHEN IT IS RECORDED USING THREE ORTHOGONAL CHANNELS. THE RESULTING 3- CHANNEL LISSAJOUS TRAJECTORY (3-CLT) SHOWS BOTH LINEAR AND PLANAR PORTIONS, WHICH WILL BE DETECTED USING ALGORITHMS TESTED UNDER REALISTIC CONDITIONS OF BACKGROUND NOISE. THE 3-CLT METHODOLOGY IS LIKELY TO BE MORE SENSITIV ...

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 PROGRAM IS DESIGNED TO ANSWER THE QUESTION WHETHER OR NOT THE ACOUSTIC EMISSION SIGNALS GENERATED BY WATER STRESS INDUCED CAVITATION IN PLANTS OCCURS PRIOR TO OR DURING IRREVERSIBLE DAMAGE TO PLANT GROWTH. THE SELECTION OF INSTRUMENTATION WITH RESPECT TO FREQUENCY, LOCATION, SIGNAL CONDITIONING, DATA PROCESSING AND ANALYSIS WILL BE EVALUATEDWITH RESPECT TOWARDS DETERMINATION OF THE PARAMETERS ...
