Le problème des perturbations, en mécanique ondulatoire, peut être traité rigoureusement et aboutit à une équation séculaire, écrite sous forme de déterminant ; on retrouve facilement les formules de Schrödinger pour un problème non dégénéré ou dégénéré ; mais cette équation permet aussi d'étudier le cas d'une grosse…

Ε. Posnjak、Tom. F. W. Barth1931-12-15Physical Review
The interpretation of the x-ray diffraction obtained from the isometric modification of lithium ferrite resulted in the conclusion that the smallest "unit" of this structure contains four anions and four cations. The anions, oxygens, occupy the four equivalent points $4b$ while the cations, iron and lithium, occupy to…

Abstract Auf Grund der Anschauungen von I. Langmuir über den Bau der Metallcarbonyle kann ein monomolekulares destillierbares Kobaltcarbonyl nicht existieren. Dagegen zeigt das monomolekulare Tricarbonylnitrosylkobalt in seinen Eigenschaften eine weitgehende Analogie zum Nickeltetracarbonyl und zum Eisenpentacarbonyl.…

In recent years there have been many advancements made in the art of analysis of three-phase synchronous machine operation. Most treatments to date have very properly stressed the theoretical point of view, the practical point of view receiving less attention due in part to the complications involved, particularly tho…

X-ray Diffraction in Crystallography
Helen Blair Barlett1931-11-01Journal of the American Ceramic Society
ABSTRACT Silicate melts containing ZrO 2 were examined by means of the X‐ray and the microscope to establish the form of crystallization of the zirconium compounds under various conditions of temperature and composition. The effect of certain fluxes on these compounds was also determined.

From the total of 143 factories in 1904, the number has decreased to 24 at the present time. Taking into account, however, the monetary depreciation since 1904, the total value of drain tile production…
