WE PROPOSE TO DEVELOP A SIMPLE TO USE, QUANTITATIVE DEVICE TO ACCURATELY MEASURE SOIL WATER CONTENT WITH SUFFICIENT RESOLUTION TO DEFINE WETTING FRONTS DUE TO RAIN EVENTS IN DEPTH PROFILES. THIS GEOPHYSICAL TOOL SENSES CHANGE IN THE ELECTROMAGNETIC ENVIRONMENT, SPECIFICALLY THE DIELECTRIC CONSTANT OF THE SOIL, WHICH IS DIRECTLY RELATED TO SOIL WATER CONTENT. THE SOIL WATER CONTENT PROFILING DEVICE ...

WITHIN THE CRYSTAL UPON THE PARTICLE'S COLLISON. THE SENSORHAS BEEN DESIGNED TO RESPOND TO THE MOMENTUM RANGE OF 2.6 X 10 -12 TO 8.9 X 10 -7 G-M/S. THIS CORRESPONDS TO PARTI-CLES HAVING A DIAMETER RANGE OF 100 TO 1500 MICROMETERS TRAVELING AT VELOCITIES OF 2.0 TO 20 M/S, THE MAIN CONSTITU-ENT OF WIND ERODED SOIL. CALIBRATION OF THE SENSOR OVER THIS MOMENTUM RANGE UTILIZING ASSORTED SIZED PARTICLES ...

THE OBJECTIVE OF THIS RESEARCH PROGRAM IS TO DEMONSTRATE THE FEASIBILITY AND DEVELOP TOWARDS COMMERCIALIZATION A LOW-COST, RELIABLE DETECTOR TO MONITOR ETHYLENE OXIDE (ETO) DOWN TO THE 0.1 PPM LEVEL. THE DETECTOR WOULD HAVE A RESPONSE TIME OF ONE MINUTE OR LESS AND WOULD FEATURE A GAS CHROMATOGRAPH (GC) COLUMN COUPLED WITH A SOLID STATE COMBUSTIBLE GAS SENSOR. AIR DRAWN AS PART OF THE SAMPLE WOULD ...

CHROMIUM DEFICIENCY CAUSES SEVERE INSULIN RESISTANCE AND GLUCOSE INTOLERANCE. AVERAGE DIETARY CHROMIUM INTAKE IN THEUNITED STATES AND OTHER DEVELOPED COUNTRIES IS MARGINAL AND MAY CONTRIBUTE TO THE HIGH FREQUENCY OF DIABETES PLAGUING DEVELOPED COUNTRIES. THE MAJOR CLINICAL CHROMIUM EVALUATIONPROBLEM IS THE ASSESSMENT OF CHROMIUM STATUS. DETERMINATIONOF CHROMIUM STATUS HAS BEEN DIFFICULT BECAUSE OF ...

IN THIS RESEARCH, NSAIDS WILL BE INDIVIDUALLY INCORPORATED INTO A DELIVERY SYSTEM. THE IN VITRO DELIVERY RATES WILL BEDETERMINED, AND THEN THE SYSTEM OPTIMIZED TO OBTAIN IN VITRO DELIVERY RATES OF 1 TO 12 WEEKS. THE VARIABLES THAT WILL BE EXAMINED TO OPTIMIZE RELEASE ARE POLYMER TYPE AND MOLECULAR WEIGHT, DRUG LOADING, AND BIOCOMPATIBLE PLASTICIZER CONTENT. FIVE NSAIDS WILL BE INDIVIDUALLY EVALUAT ...

THE OVERALL GOAL OF THIS PROJECT IS TO DEVELOP AN INNOVATIVE, FULL-LENGTH, FIBEROPTIC ESOPHAGEAL PRESSURE-MONITORING INSTRUMENT. THIS DEVICE WILL CONTRIBUTETO IMPROVED HEALTH CARE BY OFFERING SIGNIFICANTLY ENHANCED PERFORMANCE AND LOWER COST OVER CURRENT METHODS OF CHARACTERIZING PATHOLOGICAL BEHAVIOR OF THE ESOPHAGUS AND RELATED ORGANS. THE IMMEDIATE GOALS OF THE PHASE I PROJECT ARE TO DEMONSTRAT ...

THIS PROJECT WILL DEVELOP A RAPID ASSAY FOR MEASURING COLLAGENASE ACTIVITY IN GINGIVAL CREVICULAR FLUID (GCF) TO DIAGNOSE PERIODONTAL DISEASE, WHICH IS VERY PREVALENT IN THE U.S. POPULATION, AFFECTING UP TO 75 PERCENT OF ADULTS. MOST DIAGNOSTIC TECHNIQUES AVAILABLE TO CLINICIANS CANNOT PREDICT FUTURE ATTACHMENT LOSS. COLLAGENASE IN GCF IS AN IMPORTANT MARKER OF DISEASE ACTIVITY, BUT PREVIOUS METHO ...
