The form of the diffraction bands of a very fine uniform crystalline powder has been computed for the (1, 0, 0), the (1, 1, 0) and the (1, 1, 1) planes for cubical and octahedral crystals of the regular system. The shape of the bands is approximately that of the Gauss error curve. Both the shape and the half intensity…

A MATHEMATICAL THEORY WAS DEVELOPED OF EXTERNAL LOADS ON CLOSE CONDUITS AND OF THE SUPPORTING STRENGTHS OF PIPE CONDUITS. THIS THEORY APPLIES TO ALL KINDS OF CLOSED CONDUITS AND TO ALL CLASSES OF FIELD CONDITIONS ON CONDUIT CONSTRUCTION. THE THEORY WS DEVELOPED FROM EXPERIMENTS CONDUCTED OVER 20 YEARS. THE THEORY IS S…
Abstract 1. Die langsame Hydrolyse liefert nach einer gewissen Zeit, die mit abnehmender Konzentration bis zu Jahren zunimmt, in Lösungen von rund 1/10 bis über 8% Eisenchloridgehalt anisotrope Sedimente von in gleicher Richtung abnehmendem Solcharakter. Zwischen 1/3 und 1% haben diese die Eigenschaften eines Taktosol…
The Hall effect has been studied in three permalloys, the composition being 84, 81 and 78 percent nickel with the remaining part iron. The observed transverse electromotive forces are unsymmetrical for the two opposite directions of the magnetic field. This dissymmetry arises from an unsymmetrical change of resistance…

Abstract In a previous communication, Topley and Hume described the results obtained in an experimental study of the decomposition of calcium carbonate hexahydrate and showed that they could be most reasonably explained by assuming that reaction occurred only at the interface separating the two solid phases, CaCO3. 6H…

Abstract 1. Es wurde ein System von 3 Metallen gesucht, von denen zwei gegenseitig praktisch unmischbar sind, während das dritte sich in den beiden anderen bis zu hohen Konzentrationen auflöst, ohne daß deren gegenseitige Löslichkeit durch diesen Zusatz wesentlich gesteigert wird. Mischungen von Aluminium, Silber und…
Abstract 1. Es wurden folgende Doppelcarbonate dargestellt und einige ihrer physikalischen Konstanten bestimmt: Sämtliche Körper sind optisch negativ und gehören den hexagonalen bzw. trigonalen Kristallsystemen an.

By the aid of the hypergeometric function with two variables, the transition probability in the sense of the quantum mechanics between two states with positive energy in a central field due to nuclear charge $\mathrm{Ne}$ has been calculated. When the transition probability calculated is applied to the intensity of co…
These experiments show that the changes in magnetization which take place suddenly in large groups of atoms account quantitatively for the whole change in magnetization which corresponds to the steeper part of the hysteresis loop. Since it is estimated that discontinuities corresponding to groups of ${10}^{10}$ atoms…

Further studies on the isometric form of hydrated tricalcium aluminate are reported. These include methods of preparation, crystalline forms, X-ray diffraction pattern, and determinations of solubility and density.

ABSTRACT The volatility of selenium in making selenium ruby glass has been studied. About 75% of the selenium added to the batch was lost by volatilization. Sodium selenite and barium selenite were stable at 950°C and are probably stable at higher temperatures. Regardless of whether selenium or the compounds studied a…

The "resolution," at ${\ensuremath{\Phi}}_{m}$, between two electrons of velocities $V$ and $v$ both e…
