Es wird ein Verfahren zur Herstellung patientenspezifischer Annuloplastieringe vorgestellt. Der Mitralklappenannulus wird aus Computertomographiebildern modelliert. Eine optimale Ringgeometrie wird interaktiv erstellt. Die Ringe werden mittels Selective Laser Melting aus einer Titanlegierung hergestellt. Im Tierversuch wurde die Machbarkeit des Verfahrens überprüft. Mit patientenspezifisch gefo...

Der Beitrag beschreibt das Rapid Prototyping ereignisdiskreter Steuerungen. Während des Entwurfsprozesses wird mit dem Petrinetz-Zustandsraum-Modell (PNZRM) eine auf S/T-Netzen beruhende hybride Modellform genutzt. Mit Netlab steht ein Aufsatz für Matlab/Simulink zur Verfügung, der die Beschreibung ausführbarer ereignisdiskreter Modelle unterstützt und so innerhalb der Entwurfsumgebung die Mode...

We report the x-ray microtomographic imaging of three-dimensional (3D) structure of soft tissues. The transparency of biological tissue to hard x-rays enables radiographic analysis of tissue entrails. However, biological tissues are mainly composed of light elements, which produce little contrast in a hard x-ray transmission image. Tissue structures were visualized by contrasting biological con...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
