Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...

Endometrial stromal sarcoma (ESS) is a rare malignant tumor of the endometrium, occurring in the age group of 40–50 years. We report a case of low-grade ESS in a 39-year-old woman, presenting as rapid enlargement of a uterine fibroid polyp associated with irregular and excessive vaginal bleeding. Polypectomy followed by pan hysterectomy was performed. Histopathological examination and immunohis...

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...
