    Aminomalonic Acid Decarboxylase : a New Enzyme (1956)
    [s.l.] : Nature Publishing Group
    Nature 177 (1956), S. 935-936 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In the present communication, we report the presence in animal tissues of an enzyme which catalyses the decarboxylation of aminomalonic acid to glycine. This enzymatic activity was first observed in the homogenate of silk-gland tissue and afterwards in rat-liver homogenate. The enzyme solutions ...

    Excitation of γ-Rays by Fast Neutrons (1936)
    [s.l.] : Nature Publishing Group
    Nature 137 (1936), S. 398-398 
    Details

    Notes: [Auszug] IN the course of experiments on the excitation of γ-rays by slow neutrons already reported, we have noticed that in some cases an appreciable amount of observed γ-rays was due to fast neutrons. Recently, we have investigated the emission of γ-rays by the bombardment of fast neutrons, and have ...

    Energy of γ-Rays excited by Slow Neutrons (1936)
    [s.l.] : Nature Publishing Group
    Nature 137 (1936), S. 186-186 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IN a previous letter [NATURE, Jan. 4, p. 30] we have reported briefly the result of experiments determining the mean cross-section for the recombination of the proton with a ‘slow neutron’ to form a deuteron. As the continuation of it, we have recently measured the energy of a quantum of γ-rays ...

    Effect of Temperature on the Retinal Slow Potential of the Horseshoe Crab (1961)
    [s.l.] : Nature Publishing Group
    Nature 190 (1961), S. 1011-1012 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The retinal slow potentials were recorded intra-cellularly from single ommatidia of the horseshoe crab by the same procedure as that described by another author4. The temperature of the bathing solution could be varied between 6 C. and 23 C. by controlling the inflow of the cold or warm ...

    Notes: [Auszug] BY using pure metallic boron, we have recently confirmed the emission of gamma rays from this element in the presence of slow neutrons. By comparing the intensity of gamma rays with that of those emitted from cadmium, and assuming that every absorption process of a slow neutron by a cadmium ...
