For large scale applications in power engineering like transmission cables, transformers and motors different Bi-2223 tapes in long length are required. With respect to this applications we produce 55-filament tapes with a high strengthed matrix of lengths up to 600 m carrying currents up to 80 A (overall current density up to 10 kA/cm2). In short-samples critical current densities over 40 kA/cm2...
Prompted by field observations in 2001 in the Utcubamba Valley, Peru, a study was undertaken of 130 specimens in the Aratinga mitrata complex. As a result, the traditional arrangement of Aratinga mitrata (A. m. mitrata Tschudi 1844 and A. m. alticola Chapman 1921) as one species, is replaced with a new classification where Aratinga mitrata is divided into five taxa, A. m. mitrata Tschudi 1844, Aratinga mitrata chlorogenys...
Das obstruktive Schlafapnoesyndrom (OSAS) ist mit einem erhöhten Risiko für kardiovaskuläre Erkrankungen vergesellschaftet. Fragestellung In Voruntersuchungen konnte eine Prothrombinaktivierung bei unbehandelten Patienten mit OSAS nachgewiesen werden. Da diese Patienten auch andere mögliche Risikofaktoren für eine Prothrombinaktivierung aufweisen (Hypertonie, Adipositas, Diabetes mellitus, koronare...
