Objective We present our experience of microvascular decompression (MVD) for glossopharyngeal neuralgia (GPN) and evaluate the postoperative outcomes in accordance with four different operative techniques during MVD. Methods In total, 30 patients with intractable primary typical GPN who underwent MVD without rhizotomy and were followed for more than 2 years were included in the analysis. Each...
A low temperature, aqueous electrolyte fuel cell employing new, Conducting-Porous-Teflon Electrodes is described. The new electrodes show excellent performance characteristics with a variety of fuels {including hydrocarbons) and with both oxygen and air as the oxidant. Preparation methods are discussed, and performance data obtained with ambient temperature, hydrogen-oxygen and hydrogen-air cel...
We present experiments on the dynamic buckling and fragmentation of slender rods axially impacted by a projectile. By combining the results of Saint-Venant and elastic beam theory, we derive a preferred wavelength lambda for the buckling instability, and experimentally verify the resulting scaling law for a range of materials including teflon, dry pasta, glass, and steel. For brittle materials,...
construction and application of a small, light, inexpensive swivel joint suitable for infusions of small laboratory animals is described. Commercially available tubes and needles are used in the construction of the swivel thus making it easy to prepare and essentially disposable. This swivel is especially useful in long-and short-term infusions of pharmaca and nutrients in the general circulati...
