283 Dynamics of laser-induced cavitation bubbles near elastic boundaries: influence of the elastic modulus The interaction of a laser-induced cavitation bubble with an elastic boundary is investigated experimentally by high-speed photography and acoustic measurements. The elastic material consists of a polyacrylamide (PAA) gel whose elastic properties can(More)
Because of the potential impact on agriculture and other key human activities, efforts have been dedicated to the local control of precipitation. The most common approach consists of dispersing small particles of dry ice, silver iodide, or other salts in the atmosphere. Here we show, using field experiments conducted under various atmospheric conditions,(More)
While molecular tools have transformed fisheries biology, their development and implementation can necessitate the use of delicate equipment, be expensive, and require extensive optimization [1]. Counting only consumables, we have calculated that in-house sequencing of 500–700 bases on a Beckman CEQ 8000 (Beckman Coulter, Fullerton, CA, USA) costs *$4–5 per(More)
Airborne volcanic ash particles are a known hazard to aviation. Currently, there are no means available to detect ash in flight as the particles are too fine (radii < 30 μm) for on-board radar detection and, even in good visibility, ash clouds are difficult or impossible to detect by eye. The economic cost and societal impact of the April/May 2010 Icelandic(More)
