Models of steady–state plane–parallel shock waves propagating through the unperturbed hydrogen gas of temperature T1 = 6000K and density ρ1 = 10−10 gm cm−3 are computed for upstream velocities 15 km s−1 ≤ U1 ≤ 70 km s−1. The properties of the ambient gas are typical for atmospheres of pulsating stars. The shock wave structure is considered in terms of the self–consistent solution of the radiati...
BACKGROUND The authors of several studies have recommended extracorporeal shock-wave therapy as an alternative to surgical treatment for long-bone nonunions. This study was performed to compare the results of extracorporeal shock-wave therapy produced by two different devices with those of surgical treatment in the management of long-bone nonunions. METHODS One hundred and twenty-six patients...
OBJECTIVES To evaluate the efficacy of low-intensity shock wave therapy and to identify the predictive factors of its efficacy in Japanese patients with erectile dysfunction. METHODS The present study included 57 patients with erectile dysfunction who satisfied all the following conditions: more than 6-months history of erectile dysfunction, sexual health inventory for men score of ≤ 12 witho...
The behavior of shock-compressed methane at high temperatures and pressures is studied using nonequilibrium molecular dynamics and linear-scaling tight-binding electronic structure theory in simulations containing as many as 1728 molecules. For certain piston velocities, a chemical dissociation wave evolves that lags behind the compressive shock front. At about 1 ps, the dissociation region con...
