Notes: Abstract Pure autonomic failure (PAF; also known as idiopathic orthostatic hypotension or Bradbury-Eggleston syndrome) is an uncommon sporadic disorder, characterized by autonomic failure without other neurological deficits and histopathologically by cell loss in intermediolateral columns and sympathetic ganglia. Few postmortem studies of patients with PAF have been reported in the literature, and none have demonstrated Lewy bodies in distal axons, although this has been described as a feature in Parkinson’s disease with autonomic failure. We report a patient with PAF who had orthostatic hypotension and urinary symptoms for 15 years prior to death at the age of 63 years. Postmortem findings included typical and atypical Lewy bodies in the substantia nigra, locus ceruleus, substantia innominata, and sympathetic ganglia, as well as in autonomic axons in the epicardial fat, autonomic nerve fascicles in periadrenal adipose tissue, and autonomic nerves in the muscularis of the urinary bladder. Sites of autonomic nerve involvement correlated with clinical symptomatology, and thus were a valuable observation in the complete autopsy. Systemic autopsy results should be reviewed carefully in patients with PAF, as Lewy bodies in this disease may be seen in distal axons at a great length from their primary cell bodies.

Description / Table of Contents: Light turbocharger compressor wheels from aluminium and magnesium investment castingWithin the scope of a team work between Kühnle, Kopp & Kausch AG, Volkswagen AG, Sterling International Technologies Ltd. and the Fraunhofer Institute for Strength of Structures under Operational Conditions LBF compressor wheels of aluminium and magnesium investment casting were developed and tested. Strength and fatigue tests, overspeed and field tests as well as metallographic checks were made in addition to the finite element calculations to optimize the stress under centrifugal force in an appropriate way for the materials involved. The results and the knowledge gathered are to clarify whether magnesium alloys are an appropriate replacement for the proven standard aluminium alloy for turbochargers.

Notes: Im Rahmen einer Zusammenarbeit zwischen der Kühnle, Kopp & Kausch AG, Volkswagen AG, Sterling International Technologies Ltd. und dem Fraunhofer-Institut für Betriebsfestigkeit LBF wurden Verdichterräder aus Aluminium- und Magnesiurn-Feingußlegierungen entwickelt und untersucht. Festigkeits- und Schwingfe-stigkeitsuntersuchungen, Schleuder- und Feldversuche sowie metallographische Untersuchungen wurden von Finite-Element-Berechnungen begleitet, mit denen Spannungsverteilungen am Bauteil optimiert wurden. Anhand der ermittelten Ergebnisse soll geklärt werden, inwieweit Magnesium-Feingußlegierungen die gegenwärtig für Turbolader-Verdichterräder eingesetzten Aluminium-Feingußlegierungen ersetzen können.
