Novel strategies to combat dental biofilms aim at reducing biofilm stability with the ultimate goal of facilitating mechanical cleaning. To test biofilms, they need be subjected a defined stress. Here, we employed an oral care device (Airfloss) that emits microbursts compressed air and water apply shear 14-day-old plaque in 20 healthy participants no signs diseases (clinical trial no. NCT050821...

The Small Scale magNetospheric and Ionospheric Plasma Experiment (SNIPE)’s scientific goal is to observe spatial temporal variations of the micro-scale plasma structures on topside ionosphere. four 6U CubeSats (~10 kg) will be launched into a polar orbit at ~500 km. distances each satellite controlled from 10 km more than ~1,000 by formation flying algorithm. SNIPE mission equipped with identic...

Eight papers contributed by the Lincoln Laboratory Weather Sensing Group to the American Meteorological Society’s 16th Conference on Severe Local Storms, to be held October 22-26, 1990 in Kananaskis Provincial Park, Alberta, Canada, are compiled in this volume. The FAA sponsored the summer 1989 field test of the Terminal Doppler Weather Radar (TDWR) system in Kansas City, Missouri to detect win...

The plasmapause separates cold dense plasma in the inner magnetosphere from hot, low-density outer magnetosphere plasma. This boundary is very dynamic in response to changes in magnetospheric convection and other stormtime phenomena. The outer radiation belt is also dynamic during stormtime in terms of both radial location and energetic particle population. It is proposed that outer radiation b...
