    The juxtaglomerular apparatus in fetal and newborn mice (1967)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Kidneys of timed fetal and newborn mice of the C57BL stock were sectioned and stained with a modified Bowie technique. The juxtaglomerular cells, indentifiable by their granularity and position, were recognized rather late in fetal life  -  three or four days before birth. By the eighth day postpartum, the granular cells of the JGA had reached a peak of differentiation and closely resembled the adult JGA in their number, size, granularity, and position. The mesangial cell was often but not always granulated. The granular cell indices (G.C.I.) of fetal, newborn, and adult mice are compared. The high G.C.I. in fetal kidneys in our studies should account for the high renin titre found by others in fetal kidney extracts.

    Poly(norbornene): Tensile and dynamic-mechanical properties (1968)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 12 (1968), S. 1751-1754

    Notes: The tensile and dynamic mechanical properties of poly(norbornene), prepared through ring-opening polymerization, were studied. Tensile strength and extensibility increased, while Young's modulus decreased with increasing molecular weight and with increasing content of trans relative to cis unsaturation. The damping factor Delta; was dependent on molecular weight only for the lower molecular weight samples. The out-of-phase modulus E″ and the damping factor decreased as the trans/cis ratio increased.
