In many applications it is necessary to determine the diffraction pattern due to monochromatic radiation. When the x-ray beam contains two frequencies α1 and α2, the experimental pattern P(2θ) equals the sum of the contributions f(2θ) and kf(2θ−δ) of the α1 and α2 components. In this paper a graphical method of determ…
A theory of the structure of glasses is presented. It is assumed that the volume and various other properties can be computed additively from contributions characteristic of the types of “structon” present, a structon being defined as an atom surrounded by close neighbors in a specific way. If the possible types of st…

Recent cotton processing studies conducted by Textile Research Institute have demonstrated that the presence of a large number of short fibers in cotton causes appre ciable increases in processing wastes, excessively uneven rovings and yarns, less efficient spinning, and weaker yarns than would otherwise be expected.…
A theoretical and experimental analysis is given of small particle x-ray scattering by fibers. The scattering by different fibers of high orientation is compared with the theoretical scattering curves derived for independent scattering by an assemblage of parallel cylinders. Under certain conditions of swelling, excel…
The infrared spectra of NaOH, NaOD, and mixtures of these compounds have been studied at room and liquid air temperatures. The results at room temperature, taken together with the Raman spectrum of NaOH, are consistent with the x-ray structure and hydrogen positions postulated in the present work. At liquid air temper…
The rate of change of atomic moment with electron concentration for the high-temperature face-centred cubic form of the solid solution of copper in cobalt has been derived from measurements on the variation of spontaneous magnetization of suitable alloys with temperature. It is quite close to the rate previously obser…

Three samples of calcium oxide, designated as A, B, and C, were prepared from calcium carbonate labelled with calcium-45. A was heated to constant weight at 700 °C.; B was heated an additional three hours at 1400 to 1550 °C.; and C was heated six hours at the same temperature. The samples were hydrated in a supersatur…
After limit of strain hardening, fatigue crack was assumed to form as a result of large tensile stress by a piled-up group of dislocations plus externally applied tensile stress component, with the aid of other stress concentration factor associated with the obstacle or inclusion itself Nucleation theory was applied t…
