Metallic films prepared by evaporation show characteristic irreversible changes, especially if prepared at low temperatures. The changes can be explained by a decay of lattice distortions. To allow of a mathematical treatment, a set of simplifying assumptions is formulated. To initiate a decomposition of a distortion,…

The theory of dielectric polarization of polar liquids is used to calculate the dielectric constants of water and some alcohols. Quasi-rigid coordination models, based upon x-ray structural investigations, are employed in the calculation of a function g which measures the orientational correlation between neighbors in…
Gramicidin has been subjected to acid hydrolysis, and the presence in the hydrolysate of d-leucine, 1-tryptophan, dl-valine, I-alanine and glycine has been established.

For more than twenty years, investigations have been conducted at the Scripps Institution of Oceanography on the distribution and abundance of marine plankton diatoms at several stations along the Pacific coast from Scotch Cap, Alaska, to La Jolla, California. Besides these regular series of collections, numerous shor…
The crystal structure of gadolinium formate has been studied by means of Laue, rotation, and powder x-ray patterns. It has a rhombohedral lattice. The unit cell, a0=6.17A, a=115° 30′, contains one molecule, Gd(OOCH)3. Density—(calculated) 3.85, (Berman balance) 3.77. By taking into consideration the symmetry of specia…
Absorption coefficients of all elements may be calculated, from short wave-lengths up to the K critical absorption wave-length by the expression: μ/ρ=αλ3Z2(2Z/A)−βλ4Z5(2Z/A)+σeN0(Z/A). This formula holds for all elements when suitable values for α and β are chosen. Factors α and β are related to the atomic number, Z,…
Mit sternfdrmigen Probestücke u. a wurde der Einfluss der verschiedenen Elementen auf den Heissbruch des Stahlguss versucht. Die Ergbnisse sind folgendes:- 1. Die zur Heissbrüche in der nachste Beziehung stehenden Elemente sind S, Al, und Mn. 2. S und Al verstärken der Brach, die Wirkung der S ist erkennbar, obwohl si…

Abstract NaNO 2 , orthorhombic hemihedral at ordinary temperature, shows an abrupt change in the temperature coefficients of the cell constants at about 158°C. At this same temperature the original strong piezo‐electric effect disappears. The change is very probably caused by the occurrence of two symmetrical sets of…

The double scattering experiment has been repeated with a 400-kev beam of electrons obtained from a Van de Graaff electrostatic generator. The electrons are scattered by thin gold foils and are counted by Geiger-M\"uller counters. After eliminating spurious asymmetries, a polarization asymmetry of 8 percent for gold f…

Abstract Die Methode der Messung der Deporalisation des gestreuten Lichtes zur Erforschung der Molekülstruktur ist bei Fadenketten unbrauchbar, weil die Anisotropie von diesen mit zunehmender Kettengliederzahl sich kaum ändert; dagegen ändert sich aber die Intensität des gestreuten Lichtes, aus der man dem Gang der Po…
