This study evaluated the feasibility of conducting in-situ burning (ISB) using current technology on post 1967 major oil spills over 10,00 barrels in North America and over 50,00 barrels in South America and Europe. A diverse set of 141 spills representing various combinations of parameters affecting spill responses (e.g., spill size, oil type, weather conditions, sea temperature, and geographic location) were evaluated using four "Phase I" criteria: distance to populated ...
Mobile radio frequencies lie between 30 MHz and 1000 MHz. This frequency range is ideal for ceramic high Tc superconductors. We have designed Chebyshev and Butterworth filters that employ high Tc superconductors in the form of helices. In general, the performance of these filters at milliwatt power levels is excellent. We shall describe fabrication of the superconductors and filter design.
