Effects of temperature on the plastic properties of aluminium crystals
Abstract By changing the temperature of deformation, during tensile experiments on single crystals of aluminium , it has proved possible to separate reversible changes of flow stress with temperature from irreversible ones. Below 130° K the reversible change of flow stress is large; above room temperature it is hardly…
X-Ray Attenuation in Lead, Aluminum, and Concrete in the Range 275 to 525 Kilovolts
A great deal of work has been done in recent years to determine how the attenuation of an x-ray beam is modified by the contribution of radiation scattered in the absorber. This scattering contribution depends on the irradiated area and on the solid angle subtended by the detector at the absorbers. The limiting case o…

Developmental modification of fleece structure by adverse maternal nutrition
As part of a series of investigations on the factors influencing the development of the secondary follicle population during foetal and early post-natal life of lambs, the influence of severe restriction of the feed intake of ewes throughout pregnancy is recorded. Adverse maternal nutrition reduced the body weight and…
Observations on Certain Fluorescent Spots in Raw Cotton Associated with the Growth of Microorganisms
Evidence is presented which indicates that certain fluorescent spots observed in raw cotton under ultraviolet light are associated with the prior growth of microorganisms on the fiber. A striking and characteristic type of spot which fluoresces bright greenish- yellow was noted frequently in classers' samples from the…

Zur Kenntnis der Ferrate(VI)
Abstract Die Darstellung von reinem K 2 FeO 4 , Cs 2 FeO 4 , BaFeO 4 · aq und SrFeO 4 · aq wird beschrieben. Die thermische Zersetzung von K 2 FeO 4 im O 2 ‐Strom wird untersucht; sie führt höchstwahrscheinlich zur gleichzeitigen Bildung von K 3 FeO 4 und KFeO 2 .

High Field Electron Emission from Irregular Cathode Surfaces
Electron emission from a cathode surface produced by an applied field E is enhanced by the presence of projections on the emitter surface which cause a local increase in E. The nature of this enhancement factor μ(z), which is a function of the distance z from the cathode, is discussed more fully than hitherto and its…
The Shrinkage of Mold Cured Elastomer Compositions
Abstract The coefficient of expansion of elastomer compositions depends on the kind of polymer employed, the volume per cent of polymer plus all other organic materials, and the kind and the amount of pigment present. The specific effects of pigments in retarding the shrinkage are shown. A procedure is given by which…

Structural Behavior in the System (Ba, Ca, Sr) TiO 3 and Its Relation to Certain Dielectric Characteristics
The effect of strontium additions on the immiscibility region between barium titanate and calcium titanate was studied and it was found that the two‐phase gap is closed by about 18% strontium titanate when the specimens are fired at 1430°C.; at lower firing temperatures the gap is greater and there is evidence of inco…
Ferroelectric Hysteresis in Barium Titanate Single Crystals
The properties of the dynamic hysteresis loop of a c-domain BaTiO3 single crystal are examined as a function of temperature. Experimental results indicate that the coercivity and hysteresis losses decrease sharply as the crystal passes through a phase transition to a lower order of symmetry. This occurs without a subs…

Modification of the Peierls-Nabarro Model for Edge Dislocation Core
The various assumptions implicit in the Peierls-Nabarro treatment of the core of an edge dislocation are critically reviewed. It is pointed out that the lattice barrier for dislocation motion, for the case where atom rows alternate along the slip plane, has twice the period and a much higher amplitude than for the cas…
