The electronic conductivity, σ e , Hall constant, R , and thermoelectric power, Θ, in α Ag 2 Te are measured as the Ag/Te ratio is varied by the use of the galvanic cell Ag|AgI|Ag 2 Te|Pt, where the e.m.f. of the cell, E , represents the position of the Fermi level relative to Ag-saturated Ag 2 Te. According as Ag is…

Trees, or fine, branching, microscopic channels extending partly or even wholly through a wall of insulation, represent a characteristic form of latent damage. This phase of dielectric breakdown has been studied in polyethylene. The phenomenon is probably similar in other dielectrics, such as rubber, where it cannot b…
The perturbation formulas for Compton scattering with radiative corrections are written as dispersion relations. The purpose is to learn something about (1) the number of subtractions that are needed in the relations, (2) the analytic continuation of the scattering amplitude into the unphysical region, and (3) the rol…
A general examination of the effects of cellulose source and conditions of acetylation on the crystalline structure of cellulose triacetate has been carried out. Heat has been shown to markedly improve the lateral order of the structure and thereby to demonstrate the existence of two stable polymorphic crystalline for…

A packing of spheres is taken as a suitable model of porous media. The packing may be regular and the sphere size may be uniform, but in general, both should be random. Approximations are developed to give the volumes and surface areas of pendular rings that exist at points of sphere contact. From these, the total fre…

SUMMARY: Phaeodactylum tricornutum Bohlin was isolated from a marine tank at Woods Hole, Mass., U.S.A. It appeared to be identical with the Plymouth strain of ‘Nitzsckia closterium forma minutissima’. Cells were of two characteristic types, oval and fusiform, each of which remained constant for many cell divisions in…
WO 3 is monoclinic at room temperature and has a domain structure with walls of (110) and (100) twin planes. The (110) wall is displaced sideways by a pressure externally applied along the b axis, resulting in the change of the axis b to the shorter axis a . The (100) domains change to a single domain by stress X z .…

Summary: A revised taxonomic description of Phaeodactylum tricornutum Bohlin is presented, with special emphasis on the details of the silica valve, a structure hitherto unobserved. The features distinguishing P. tricornutum from Nitzschia closterium (Ehr.) W. Sm., with which it has frequently been confused, are summa…
