THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF INCREASING THE QUANTITY AND QUALITY OF SCIENCE EDUCATION IN ELEMENTARY SCHOOLS THROUGH UTILIZING SCIENCE EDUCATION AS THE CONTENT OF CHOICE FOR A RELATIVELY NEW ADDITION TO THE ELEMENTARY SCHOOL CURRICULUM, FOREIGN LANGUAGE. THE INCLUSION OF FOREIGN LANGUAGE IN THE ELEMENTARY SCHOOL, MORE COMMONLY CALLED FLES, IS A RAPIDLY GR ...

THE FOREST PRODUCTS INDUSTRY HAS MADE USE OF GEOGRAPHIC INFORMATION SYSTEMS (GIS), FOREST GROWTH AND YIELD MODELS (FGYM), AND TIMBER HARVEST OPTIMIZATION ROUTINES (THOR) FOR MANY YEARS. HOWEVER THE PRIMARY DEVELOPMENT OF THESE TECHNOLOGIES HAS BEEN PROPRIETARY, LIMITED TO CERTAIN GEOGRAPHIC REGIONS OF THE COUNTRY, AND/OR RESTRICTED TO USE ON MAINFRAME COMPUTERS. LIMITED PUBLISHED RESEARCH IS AVAIL ...

WE PROPOSE TO INVESTIGATE THE USE OF ELECTRON BEAM STERLIZATION OF HOSPITAL WASTE AS A MEANS OF OVERCOMING THE LIMITATIONS OF EXISTING HOSPITAL WASTE STERILIZATION TECHNIQUES. WHEN COMBINED WITH A SHREDDER WHICH REDUCES THETHICKNESS OF THE WASTE, AND RENDERS THE THICKNESS MORE UNIFORM, ELECTRON BEAMS IN THE 3-4 MEV, AND 3-20 KW RANGE A ARE IDEAL FOR THIS TASK. ONGOING PROGRAMS AT NORTH STAR RESEAR ...

INTENSE X-RAY SOURCES HAVE BEEN USED IN GEOPHYSICAL RESEARCH PODS TO DETERMINE STRATA FORMATION DENSITY, LITHOLOGY, AND POROSITY. THE SCATTERING OF -RAYS FROM (137)CS OR (60)CO SOURCES WITH DECAY ACTIVITIES OF UP TO SEVERAL CI HAVE BEEN USED EXTENSIVELY IN BOREHOLE LOGGING. A NON-RADIOACTIVE PHOTON SOURCE IS HIGHLY DESIRABLE SINCE IT REDUCES THE RADIOLOGICAL HANDLING RISK AND THE RISK OF DOWN HOLE ...

ION BEAM FIGURING TECHNIQUES WILL BE APPLIED TO FIGURE ASPHERE OPTICAL ELEMENTS. A MIRROR WILL BE ASPHERIZED TO REMOVE THE R(0)6 ZERNIKE CONTRIBUTION TO CORRECT FOR THIRD-ORDER AND FIFTH-ORDER SPHERICAL ABBERRATION AND DEFOCUS. IN ADDITION, A PHASE CORRECTION PLATE WITH THE SAME OPTICAL CORRECTION WILL BE INVESTIGATED FOR FABRICATION. SIMULATED ION BEAM FIGURING OF MORE COMPLEX ELEMENTS WILL BE IN ...

ECONOMICAL METHODS OF REMOVING AND/OR RECOVERING DISSOLVED ORGANICS OR METALS FROM WATER ARE NECESSARY FOR US INDUSTRIAL COMPETITIVENESS. ALSO, FIRMS SPECIALIZING IN HAZARDOUS WASTE DISPOSAL AND POLLUTION CONTROL WILL BE A MAJOR AREA OF INDUSTRIAL GROWTH IN THE US. MICELLAR-ENHANCED ULTRAFILTRATION (MEUF) IS A NEW PROCESS WHICH CAN REMOVE DISSOLVED ORGANICS AND MULTIVALENT METAL IONS FROM WATER. I ...

THE COMBINATION OF GAS CHROMATOGRAPHY WITH MASS SPECTROMETRY(GC/MS) PROVIDES THE BEST GENERAL PURPOSE ANALYTICAL INSTRUMENT FOR SENSITIVE CHARACTERIZATION OF COMPLEX MIXTURES. IT IS USED IN THE FIELDS OF CHEMISTRY, BIOLOGY, GEOCHEMISTRY, ENVIRONMENTAL SCIENCE AND FORENSICS. IN MOST CASES, THE GAS CHROMATOGRAPH SEPARATES THE STARTING MIXTURE INTO ITS CONSTITUENT COMPOUNDS PRIOR TO ANALYSIS BY THE M ...
