    Need for the Redetermination of the Atomic Weights, of Uranium, Thorium, and Radium (1924)
    [s.l.] : Nature Publishing Group
    Nature 114 (1924), S. 717-718 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] IT is known that the atomic weights of such radio-elements as have been determined experimentally agree approximately with those to be expected on radioactive theory, and also that small unexplained discrepancies appear when the actual instead of the approximate values are considered. The ...

    The Isotopes of Lead (1923)
    [s.l.] : Nature Publishing Group
    Nature 112 (1923), S. 619-620 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] IT was suggested by the writer in 1912 that the end-products of the uranium and thorium disintegration series should differ in atomic weight from that of common lead, which chemically they closely resemble. As the atomic weights of these products, determined experimentally later by Richards and ...

    A Calculation of the Atomic Weights of Isotopes (1923)
    [s.l.] : Nature Publishing Group
    Nature 112 (1923), S. 588-589 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] SOME months ago, when engaged on a study of radioactive disintegration series, the results of which appeared in the October issue of the Philosophical Magazine, I was able to formulate simple rules from radioactive data which enabled me to calculate a list of the atomic weights of the principal ...

    The Relation of Actinium to Uranium (1923)
    [s.l.] : Nature Publishing Group
    Nature 111 (1923), S. 703-704 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] AT present the most likely view of the origin of the actinium series is that uranium II undergoes a dual change in which about 96 per cent, of atoms form ionium and the radium series, and the remainder form uranium Y, the product of which, proto-actinium, is the parent of the actinium series. ...

    Transplantation antigens in Crohn's disease (1975)
    Springer
    Digestive diseases and sciences 20 (1975), S. 359-361 
    Details
    ISSN: 1573-2568
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract The complete HL-A antigen profile was examined in 77 patients with Crohn's disease, 11 of whom had unequivocal ankylosing spondylitis. There was no significant difference in the frequencies of the HL-A antigens between these 77 patients and 600 normal controls. 10 male patients with Crohn's disease possessed HL-Aw27; all of these had unequivocal ankylosing spondylitis. This antigen may, therefore, be a useful marker of spondylitis in Crohn's disease.
