Not Available This proposal describes an innovative, ultrashort pulse laser system offering environmental stability, compactness and extremely high efficiency. This will be achieved by the use of a novel diode-pumped, mode-locked ytterbium fiber laser and fiber pulse stretcher, followed by a diode-pumped Yb:YAG amplifier and compact grating compressor. This system will deliver the >5mJ, subpicose ...

Not Available Adaptive optics systems for imaging or beam projection through the atmosphere are designed to compensate for the optical effects of turbulence. These effects enter in as phase perturbations distributed along the propagation path. Conventional adaptive optics systems attempt to compensate for these effects by means of phase-only corrections applied at a plane conjugate to the apertur ...

Not Available Polymeric membrane optics are leading candidates for lightweight space-based optical systems. Significant advances have been made in the understanding of the mechanisms contributing to the shape distortion of the membrane. This Phase I proposal will couple the detailed analytical understanding with an innovative polymeric material and fabrication process. Test samples of the polyimi ...

VARIOUS ACTIVITIES (EDUCATION, GOVERNMENT, RESEARCH) GENERATE LARGE AMOUNTS OF RAW DATA. HOWEVER, DATA IS COLLECTED IN A DISJOINTED AND ISOLATED FASHION (I.E., ACTS, LITERATURE) CREATING BARRIERS IN DATA ACCESS AND DISSEMINATION. THERE IS A CONSENSUS AMONG FAMILIES AND PROFESSIONALS, THAT NEEDS OF INDIVIDUALS WITH DISABILITIES AND SERVICES PROVIDED TO THESE INDIVIDUALS COULD BE GREATLY IMPROVED IF ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

THESE IS A GREAT NEED FOR A SAFE, ENERGY-EFFICIENT, ON-SITE METHOD FOR DECONTAMINATING VARIOUS CHEMICAL TOXINS. NEARLY ALL (I.E., 99.8%) OF THE POLYCHLORINATED BIPHENYLS (PCBS) FOUND IN CURRENT APPLICATIONS ARE USED AS DIELECTIC FLUID. THIS AMOUNTS TO ABOUT 30,000,000 GALLONS OF PCB-CONTAMINATED FLUID. TO REDUCE THIS EXPOSURE RISK THE ENVIRONMENTAL PROTECTION AGENCY IS REQUIRING THE ACCELERATED PH ...

THIS STUDY DESCRIBES THE RESEARCH CONDUCTED TO IDENTIFY THE VARIETY OF MOLD OR YEAST WHICH DEGRADES LEACHATE FROM HAZARDOUS WASTE LANDFILLS IN A COMPLETELY-MIXED, AEROBIC REACTOR. THE RESEARCH ALSO EXAMINES ALTERNATIVE PRETREATMENT STEPS WHICH MAY BE NECESSARY TO OVERCOME THE LIMITATIONS IN BIOLOGICAL DEGRADATION DUE TO THE PRESENCE OF TOXIC SUBSTANCES OR NUTRIENT DEFICIENCIES. FURTHER, THE RESEAR ...
