A two-dimensional balance model of populations distributed by property was developed using the ordinates of particle diameter andparticle density. This model makes it possible to calculate the spectrums of granulation changing over time in the fluidized bed duringbatch operation and in addition to calculate the time-dependent size distribution of the product granulate for continuous...

The inaugurator of transmitted echocardiography: Prof. Dr Wolf-Dieter Keidel.

Usually, the inauguration of clinical echocardiography is attributed to Edler and Hertz who published their first paper in 1954, followed by Japanese authors in 1956. It is less well-known that there was a first description on using ultrasound for investigating the heart by Wolf-Dieter Keidel already a decade earlier (Figure 1). His first investigations were conducted at the Physiologic Institu...

The antimonides RE2Ir3Sb4 (RE = La, Ce, Pr, Nd) were synthesized by arc-melting of the elements and subsequent annealing or via high-frequency melting. The samples were characterized by X-ray powder diffraction, and the four structures were refined from single-crystal X-ray diffraction data: Pr2Ir3Sb4 type, Pnma, Z = 4, a = 1621.9(2), b = 458.60(8), c = 1099.8(1) pm, wR2 = 0.036, 1558 F2 values...
