Illumination of a sodium chloride crystal at liquid nitrogen temperature after x-ray irradiation at a higher temperature or higher temperature annealing has two effects upon its thermoluminescence: Glow peaks stable at the temperature of x-ray irradiation or annealing are diminished in intensity. Missing glow peaks, u…

The infrared spectrum of KOH has been obtained in the region 4000–300 cm—1. At 23°C the spectrum shows two broad bands, one at 3600 cm—1 and the other at 643 cm—1. At —180°C the O–H stretching band near 3600 cm—1 appears as a doublet. Splitting is shown to arise from coupling between the two OH— ions in the unit cell.…

An attempt has been made to establish a mechanism for stress corrosion by direct observation on the propagation of cracks in α-brass tested under ammonia. The observations indicate that failure might be described by a two-stage process, of local embrittlement, followed by a cleavage-like fracture. Such a model demands…
Data on the diffusion of Ar in sanidine, microcline, phlogopite, glauconite, and leucite are presented. We conclude from these data that: 1) Dynamic lattice changes markedly influence Ar loss at the time of the changes. 2) If Ar diffusion takes place under conditions of no lattice changes, all Ar will be lost at a sin…
Detailed results are presented on the absorption and desorption of water vapour (0—100% r.h., 30°—90°C) by cellulose triacetate, secondary cellulose acetate, ethyl cellulose, drawn nylon 6.6 yarn, Terylene, Orlon, wool and Fibrolane. The sorption characteristics of the samples were stabilized prior to the sorption mea…
The initiation of localized cracking in hydrogenated highstrength steel was dependent on the development of a critical hydrogen concentration and relatively insensitive to the magnitade of the applied stress. The stress was believed to influence the delayed failure process by providing the means for grouping the hydro…
The thermomagnetic properties of a compound Mn 2 As were investigated together with the phase diagram of Mn–As system. From the results of measurements of the temperature dependence of magnetic susceptibility and specific heat of the compound Mn 2 As, it was found that this alloy is antiferromagnetic with the Néel poi…
As connective tissue ages, the following changes have been observed: (1) a reduction in its swelling properties as noted by Banfield (1) and Elden (2); (2) an alteration in the contraction and relaxation of collagen described by Banga et al. (3) as well as by Verzar (4) ; (3) an increase in the size of collagen fibers…

Abstract This paper reviews the behavior of aluminum in contact with natural waters. The influence of water composition and service factors on corrosivity to aluminum are discussed. Laboratory pitting test methods are described and data are presented to support the existence of a cube root (in time) rate curve for the…

When a textile yarn is impacted transversely, strain waves and transverse waves which " travel outwards away from the point of impact are initiated. Each strain-wave front travels at constant velocity. A transverse-wave front, however, changes its velocity each time it meets a reflected strain-wave front. This effect…
