Bending Settlement of a Slab Resting on a Consolidating Foundation
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.
Electrostatic Electron Lenses with a Minimum of Spherical Aberration
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…

The course and mechanism of autoxidation reactions in olefinic and polyolefinic substances, including rubber

Theory of the Elasticity of Polycrystals with Viscous Grain Boundaries
Previous experiments have shown that in annealed polycrystalline specimens, the grain boundaries are much more susceptible to plastic shear than are the interiors of the grains. This paper investigates the elastic properties of a specimen in which the grain boundaries are incapable of supporting shearing stresses. In…
The carbohydrate content of collagen
Colorimetric methods are uscd to study the carbohydrate in preparations of collagen made from hide, tendon, and bone. It was found that the three preparations all contain the same amount of the same kind of carbohydrate. This result confirms the indication of other experiments, namely, that the white fibrous connectiv…
Further Studies on the Oxidation of Nitric Oxide; the Rate of the Reaction between Carbon Monoxide and Nitrogen Dioxide
The initial rate of the reaction between CO and NO2 from 225°C to 290°C was measured under conditions which precluded the possibility of NO2 decomposition. This study extends the earlier data on the reaction over a 300° temperature interval. The oxidation of nitric oxide at 25°C and at pressures from 0.01 to 0.1 mm of…
Chemical composition and genesis of glauconite and celadonite
A method of study found applicable to the clay minerals clarifies the chemical relations of glauconite and celadonite, and gives significant information about their genesis. The representative formula of glauconite is: (K, Ca 1/2 , Na) . 84 (Al . 47 Fe... . 97 Fe.. . 19 Mg .40 ) (Si 3.65 Al . 35 )O 10 (OH) 2 and of ce…
Frictional Phenomena. V: B. Liquids
THIS chapter presents theories of liquid viscosity, particularly those of van der Waals, Andrade, Prandtl, and Eyring. Whereas the viscosity of gases is based on the collisions of molecules, that of liquids is dominated chiefly by molecular attraction forces. Experimental material is presented on the effect of chemica…
A new precision refractometer
A refractometer capable of giving refractive indices and dispersions to one unit in the fifth decimal place is described. The samples are smooth ground, but not polished, and require little care in preparation. A complete determination (Na D, C and F lines) can be made in 1-2 hr. This compares very favourably with the…

A solution of the decision problem for the Lewis systems S2 and S4, with an application to topology
In this paper I shall give a solution of the decision problem for the Lewis systems S2 and S4; i.e., I shall establish a constructive method for deciding whether an arbitrary given sentence of one of these systems is provable. The method is laborious to apply, since, in order to decide by means of it whether a given s…
