Colonic diverticulitis: diagnostic value and appearance of inflamed diverticula–sonographic evaluation
Acute bowel inflammation frequently originates from thin-walled diverticula of the colon. Not the presence of diverticula, but the demonstration of an inflamed diverticulum, is diagnostic of diverticulitis in...

Conditions for XUV amplification considering recombination in clusters
cm-l for a wavelength of λR≈200 Å in a time ≲1 ps can be expected. The measurable gain Greal depends on the cluster density Ncl. For Ncl≈1016 cm-3 we expect Greal≳20 cm-1.

Decrease of Radiation Trap** in a Laser-Produced Plasma with Volume-Reducing Deviations from Cylindrical Geometry
In optimizing X-ray laser schemes based on laser-produced plasmas, a precise prediction of the amount of radiation trap** and its influence on the gain is of current interest (cf. 1, 2 | ). The re-absorption...
