    Description / Table of Contents: Zusammenfassung In der vorliegenden Veröffentlichung wird über das dynamisch-mechanische Verhalten einiger zusammengesetzter Polymersysteme berichtet. Diese Systeme wurden durch Vulkanisieren von cis-1,4-Polybutadien mit einer gewissen Menge von Methacrylsäure oder Magnesiummethacrylat hergestellt. Die erhaltenen Ergebnisse sind mit dem aufgestellten Strukturmodell in Übereinstimmung.
    Notes: Summary In the present paper we report the dynamic mechanical behaviour of some composite systems. These systems were obtained vulcanizing the cis-1,4-polybutadiene in mixture with a different amount of methacrylic acid or magnesium methacrylate. The obtained results support our structural model.

    Blue objects in the field of M31 (1976)
    Springer
    Astrophysics and space science 44 (1976), S. 405-408 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract This paper gives the results of a photometric study of star-like blue objects Nos. 14, 15, 16, 17, and 18 discovered by Börngenet al. (1970) in the field of M31 and of the QSO OA 33. Three of these objects-Nos. 14, 16 and 17-exhibit variable light. No. 14 is a probable U Geminorum-star; No. 16 is a QSO and very likely also the No. 17. Finally, we suggest a candidate for the optical counterpart of OA 33.
