    Notes: [Auszug] A cylindrical brass-bodied proportional counter has been used mounted with its axis at right angles to the diffracted X-ray beam, which enters by a thin beryllium window. The counter was filled to atmospheric pressure with argon plus ethylenc. Amplified counter pulses pass through a variable-width ...

    Notes: [Auszug] Dry ammonium thiocyanate (0-1 gm.) and acetic anhydride containing 10 per cent acetic acid (1 -0 ml.) are heated with the benzoylated dipeptide (0-1 gm.) for 30 min. on a boiling water-bath. After cooling the orange solution, 50 ml. of water is added, the mixture left overnight, and the light brown ...

    Notes: [Auszug] Absorption was studied in rats of 100-200 gm. by Sols and Ponz's method7'8. Three or four successive absorptions were carried out in the same intestinal loop of each animal. The hexoses remained at 5-4 per cent and the pentoses at 4-5 per cent dissolved in water or in phosphate solutions or other ...

    Notes: [Auszug] We have now measured the recovery of the resistivity of gold wires. A gold wire, which had been soft-annealed, was stretched approximately 7 per cent at liquid-air temperature and its resistance measured. This elongation caused a relative increase of the resistivity of about 1-5 per cent. The wire ...

    Notes: [Auszug] The kinetic assumption underlying Hiittig's theory is that all molecules of each layer may evaporate, whereas in the Brunauer-Emmett-Teller theory only uncovered molecules are allowed to do so. Hiittig's mechanism of desorption is rather unrealistic from the point of view of the multilayer model in ...
