    Long-term experience in using iotrolan for paediatric gastrointestinal studies (1994)
    Springer
    European radiology 4 (1994), S. 371-376 
    Details
    ISSN: 1432-1084
    Keywords: Contrast media ; Gastrointestinal tract ; Infants ; Iotrolan ; Radiography

    Notes: Abstract Over the past 5 years we have used the new dimeric, non-ionic, water-soluble contrast agent iotrolan (Isovist-300) in 370 studies of the paediatric gastrointestinal tract. Iotrolan is by far the best accepted and tolerated contrast agent for young children. Because of its iso-osmolality it can be used without dilution. No ill effects were reported in cases of aspiration or perforation. In all studies very high contrast images were obtained and the required diagnostic information was provided. The only disadvantage of iotrolan is its present high price. However, in view of the small volumes required in children (10 ml is sufficient in 59% and 20 ml sufficient in 92% of investigations) this should not be a major obstacle to its use. Iotrolan promotes a much greater readiness among paediatricians and paediatric surgeons to have gastrointestinal studies performed on very small and very sick babies.

    The spectrum of X-ray manifestations in Cockayne's syndrome (1981)
    Springer
    Skeletal radiology 7 (1981), S. 173-177 
    Details
    ISSN: 1432-2161
    Keywords: Cockayne's syndrome ; Bone deformities ; Children, growth and development ; Premature aging ; Thymic hormone

    Topics: Medicine
    Notes: Abstract Cockayne's syndrome is a rare familial disorder characterised clinically by premature aging, appearing progressively from the third year on. The radiological manifestations of eight affected children have been studied and summarised. It is concluded that a skeletal survey can provide a roentgenologic pattern suggesting the diagnosis, even when it is inconclusive from the clinical signs during the first years of life. The aetiology of this syndrome is unknown, but the authors postulate the possible role of a defect of thymic hormone which has been found in all their cases.

    Leichte Turbolader-Verdichterräder aus Aluminium- und Magnesium-Feinguß (1997)

    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.

    Molecular configuration of polystyrene in benzene (1963)

    Notes: The particle scattering factor P(ϑ) with Gaussian statistics for polydispersed systems has been treated. For a polystyrene sample with a sharp molecular weight distribution (Mw/Mn 〈 1.02, Mw = 1.5 X 106), the measured angular dependence of scattered intensity indicates that the polymer coil does obey Gaussian statistics. This holds for a range of concentrations provided the variation of the constant representing the radius of gyration with concentration is adjusted.
