RESEARCHERS ARE DEVELOPING AND DEMONSTRATING ADAPTABLE VIBRATION ANALYSIS SENSORS WHICH USE SPECIALIZED WEIGHTED-SENSITIVITY OPTICAL FIBER WAVEGUIDE STRUCTURES. SEVERAL METHODS TO CREATE THE NECESSARY SENSITIVITY VARIATIONS ALONG THE LENGTH OF THE WAVEGUIDE ARE SUGGESTED. EXTENSIONS OF THIS WORK TO FURTHER PERMIT THE REAL-TIME MODIFICATION OF SUCH SPATIAL FIBER SENSITIVITY PROFILES, AND HENCE THE ...

VOLATILE HALOGENATED ALIPHATIC COMPOUNDS (VHALS) ARE PREDOMINANT CONTAMINANTS AT HAZARDOUS WASTE SITES. TRICHLOREOTHYLENE (TCE) IS THE MOST COMMONLY OCCURING COMPOUND IN THIS CLASS. THESE COMPOUNDS ARE PERSISTENT AND THEREFORE REQUIRE SOME FORM OF REMEDIATION OF REMOVAL. PRESENT TECHNOLOGY UTILIZES CARBON ADSORPTION, WHICH MEANS TRANSFERRING THE HAZARDOUS COMPOUNDS TO ANOTHER MEDIUM WHICHMUST BE D ...

THE U.S. FOREST SERVICE HAS DETERMINED THAT BECAUSE OF LONG-TERM HARMFUL EFFECTS TO THE ENVIRONMENT, AND HUMAN HEALTH RISKS, A REDUCTION IN THE USE OF CHEMICAL PESTICIDES IS NECESSARY. IN A DRAFT ENVIRONMENTAL IMPACT STATEMENT (1989), THE FOREST SERVICE, PACIFIC NORTHWEST REGION, HAS ADOPTED A PEST MANAGEMENT POLICY WHICH WOULD GIVE PREFERENCETO NON-CHEMICAL PEST CONTROL MEASURES. UNFORTUNATELY, S ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.
