The Maxwell relaxation theory leading to the concept of a viscous-elastic body is briefly stated. Extensions to systems built up from several such viscous-elastic components with different relaxation times are discussed. In the case of high molecular weight materials, it is more appropriate to assume a continuous dist…
The theory of Schottky emission is extended to include in the current those electrons which tunnel through the top of the potential barrier at the metal surface when rather strong electric fields are used. It is found that these tunnelling electrons contribute to the periodic deviations from the Schottky line, increas…
The problem of the mechanism of diffusion in metallic copper is discussed from the standpoint of the modern theory of metals. Three competing processes are considered in detail, namely the mechanism of direct interchange of atoms, the mechanism of interstitial diffusion, and the mechanism of vacancy diffusion. The ene…
The x-ray interference is calculated for layer lattices in which the phase shifts between consecutive layers and the scattering powers of individual layers do not follow a strictly periodic arrangement. In the second section the scattering power of all layers is assumed to be the same but the phase shifts can take on…

Abstract 1. Es werden die Fällungen untersucht, die entstehen, wenn gemischte Lösungen von 1‐m. bzw. 0,1‐m. Aluminium‐ und Calciumchlorid wechselnder Menge mit einem geringen Überschuss an Natronlauge gefällt werden. Bei mittleren Mischungsverhältnissen entsteht bei beiden Konzentrationen eine Doppelverbindung, die da…

The major protein component of muscular tissue, myosin, has occupied the attention of many investigators because of its extreme importance as the contractile element of living. muscle. When isolated from the tissue it has many of the properties of the globulins, but its extreme molecular asymmetry gives rise to intere…
<div class="htmlview paragraph">THIS paper attempts to clarify the functioning of the volute spring and to eliminate the confusion which is at present connected with volute-spring computations. A number of contradictory formulas are currently in use, many of them usable only for one coil or for half a coil at a…
The ΔE-effect (change in Young's modulus of elasticity with magnetization) in the annealed state of iron-cobalt alloys has been measured at the room temperature by the method of magnetostrictive oscillation. The measured range of magnetic field is up to about 900 oersteds. It was found that the negative ΔE-effect occu…

The calculation of the settlement and bending of an elastic slab resting on a consolidating foundation under the action of a load concentrated on a line. Two cases are considered: first, when the slab is perfectly pervious to water, and second, when it is impervious. The problem is two-dimensional.
A method is suggested for the construction of electrostatic electron lenses by building equipotential surfaces whose position in space is calculated from an assumed axial potential. The calculations are carried through for examples of symmetrical and immersion lenses. The symmetrical lens chosen is the well-known one…
