A spectral discretization of the equal width equation (EWE) is presented. The method is shown to be convergent and nonlinearly stable. Time-stepping is performed with high-order Adams methods. The spectral accuracy of the scheme reveals some features of the EWE that the methods previously used could not bare out properly. For instance, we may now study the changes in amplitude and velocity of solitary waves after collisions.
Seventy ganglia of the wrist have been treated by a new method whereby two sutures are passed through the ganglion, at right Cheap Nike Free Run 2
angles to each other, and each is tied in a loop. At intervals thereafter, the contents of the ganglion are expelled by massage. Only three recurrences occurred in 62 patients followed-up. This compares well with the results of surgical excision and avoids the complications of operation and anaesthetic.
Isosteric heats and differential entropy curves were measured for argon adsorbed on one, two, and six nominal ethylene layers in the range 65–84°K. Adsorption hysteresis behavior was observed at low temperatures (65–75°K) and was investigated in detail on both one and two ethylene layers. Further evidence for phase transitions involving two-dimensional condensed. states, rather than capillary pore filling, is presented.
