The last comprehensive publications about the theory and practice of rhinomanometry appeared more than 20 years ago. Since the 1980's, the general progress of sensor techniques, fluid physics and data processing was accompanied by the permanent work of the authors to analyze the errors of rhinomanometry and to create a fundament for a contemporary and(More)
The number of thoracic injuries associated to traumatic fractures of the spine is increasing. The multiple trauma rate in this retrospective study of 253 spinal injuries with neurological damage, which needed admission to the Intensive Care Unit, was of 55%. Blunt chest trauma was found in 86% of the multiple trauma group, especially in combination with(More)
Massive osteolysis is a very rare tumour-like lesion usually affecting young adults. There are 132 reported cases which we have reviewed, including 31 single cases of pelvic involvement. The term "massive osteolysis" is based on the typical radiological findings, such as increasing translucency and loss of bone density. The diagnosis of the Gorham-Stout(More)

A survey of the frequency of associated malformations occurring with anorectal anomalies reviewing a large number of cases has been carried out. The urogenital tract, the extremities and the skeleton are most commonly involved. Esophageal atresia and hypospadias are the most important associated malformations. It was impossible to classify the associated(More)
Given, in an arbitrary spacetime (M, g), a 2-dimensional timelike subman-ifold Σ and an observer field n on Σ, we assign gravitational, centrifugal, Coriolis and Euler forces to every particle worldline λ in Σ with respect to n. We prove that centrifugal and Coriolis forces vanish, for all λ in Σ with respect to any n, if and only if Σ is a photon(More)
1. [3H]ouabain binding to human erythrocyte membranes is a time- and temperature-dependent process. The association of ouabain to the membrane-bound receptor follows second-order kinetics, while the dissociation is a monomolecular reaction. An association rate constant of 4-6 x 10(4) M-1 sec-1 and a dissociation rate constant of 1-4 x 10(-4) sec-1 were(More)
BACKGROUND AND OBJECTIVE The growing Anglicization of the German language especially affects medicine. This is true not only in medical research but also for congresses and publications. This leads to far-reaching consequences also for continuing medical education. This questionnaire study obtained the opinions by a selected group of doctors attending a(More)
In Schwarzschild spacetime the value r = 3m of the radius coordinate is characterized by three different properties: (a) there is a " light sphere " , (b) there is " centrifugal force reversal " , (c) it is the upper limiting radius for a non-transparent Schwarschild source to act as a gravitational lens that produces infinitely many images. In this paper(More)
Characteristics of citation and language in publications of German authors from the journal "Der Chirurg" (vol 78, 2007) were analysed. Out of a total of 3,342 citations, 756 (22.62%) were from German authors with 248 (32.8) self-citations. The hegemony of the impact factor in science, research and education is critically discussed. The imbalance between(More)
