An expression is derived for the strength of the blended yarn spun at optimum twist, in terms of the strengths of yarns spun from the two components at optimum twist. Good agreement between the predicted and observed values is found over a range of cottons and counts. The strength deficiency of the blended yarn is par…

The Mössbauer spectrum of FeAl 2 O 4 consists of three absorption peaks at 0, 1.46 and 2.56 mm s -1 relative to a 57 Co/Cu source. The spectrum can be resolved into two quadrupole-split spectra. The outer pair of lines corresponds to a quadrupole splitting of 2.76±0.10 mm s -1 and an isomer shift of 1.52±0.10 mm s -1…

Deuterated hydrogrossular, Ca3Al2(O4D4)3, has been prepared in order to investigate, by neutron and x-ray diffraction, the isomorphic substitution of (O4H4)4− for (SiO4)4 −. A polycrystalline specimen yielded the cubic-cell edge, 12.5755 ± 0.0009 Å (28°C) and oxygen parameters x = 0.0303(3); y = 0.0547(4); z = 0.6430(…
The crystal structure of interstitial solid solution of zirconium-oxygen system was investigated by means of X-ray, electron and neutron diffraction on specimens in the composition range between 11 and 27 at% O. The specimens were prepared by melting appropriate mixtures of zirconium metal and zirconium dioxide in an…
The nature of the extensional response of anisotropic cylinders, such as helical-wound composite tubes, under various end con ditions is investigated analytically and experimentally. Of particular interest is the existence of a uniform state of stress under practical testing conditions. Also considered is the influenc…

Through an investigation of the transport and related thermodynamic properties of TiNi at and around its ``martensitic'' transition temperature, the existence of a critical range extending over a 60°C interval is established. Within this critical range, the phase transition is second order. Irreversibility of various…

In separate experiments, mature rats were either given a ration containing L. leucocephala leaf meal at 15% or 7 3% level, or dosed orally each day with water extract of the leaf meal before and during the breeding period. At the 15% level, the food intake of the rats was greatly reduced, and they showed general sympt…
The electrical conductivity of magnesium oxide single crystals has been measured for the first time in the temperature range 400-750°C. Results agree well with those obtained by other workers at higher temperatures and a single activation energy of about 2·8±0·1 ev seems to apply from 400 to 1800°C. Fields varying fro…
Change-transport phenomena in thin films of vanadium dioxide have been investigated. This paper presents conductivity, Hall coefficient, and thermoelectric power data for reactively sputtered vanadium dioxide thin films both above and below the metal-semiconductor transition. Measurements were made both on single-crys…

A semidestructive method has been developed for determining the principal residual stresses and directions in rectangularly orthotropic materials. The reduction equations are based upon a set of functions that describe the surface strain-relaxation field about a hole drilled to a limited depth into the material. Three…
