The problem considered is the interpretation of the tensile properties of twisted continuous-filament yams in terms of their geometrical structure and the properties of the constituent filaments. The theory developed for this purpose has the following principal features. (1) It is a large-strain theory, (2) Constancy…
A theory of the high temperature lattice thermal conductivity of semiconducting alloys is described in which normal processes are taken into account by the use of Callaway's method. This theory is in good agreement with data on germanium-silicon alloys, published recently by Abeles et al. , but it is shown that the th…

The saturation magnetostrictive constants of a magnetic material may be determined by means of ordinary ferromagnetic resonance. For small strains, the magnetic field required for resonance at a given frequency is a linear function of the applied uniaxial stress. The magnitude of this shift may be directly related to…
A powder neutron diffraction study of stoichiometric NiS has been made in the range 85–770°K. The NiAs-type structure can be obtained at room temperature by quenching from above 700°K. This NiAs form exhibits a paramagnetic-antiferromagnetic transition at 263°K. In the antiferromagnetic state the moments in a hexagona…
Pleochroism of the infrared absorption of muscovite has been measured under moderate resolution. The results are discussed in terms of the idealized mica structure. From the pleochroism of the OH stretching band, orientation of the vibrational transition moments can be determined. These moments are tilted out of the c…
The magnetostriction of single-crystal yttrium iron garnet (YIG) has been measured from liquid nitrogen temperature to 450°K. The theory of magnetostriction of cubic crystals has also been extended to Néel ferrimagnets. The theoretical predictions of the temperature-dependent magnetostriction coefficients h1 and h2 ar…

The direction of easy magnetization in pyrrhotite deviates from the (001) plane below 205°K. We have measured the thermal variations of the anisotropy constants and the spontaneous magnetization between 4.2° and 292°K and determined the fraction of Fe3+ ions on each sublattice.
A series of constant strain range tests was made for a wide variety of materials producing fatigue lives varying from a few cycles to about one million cycles. The specimens were subjected to axial, compression-tension, low-frequency fatigue about a zero mean strain. Load range was measured periodically throughout eac…

Abstract The view that the glass transition is basically thermodynamic in nature is used to derive an expression for glass temperature depression by plasticizers. The second‐order transition temperature is given as that temperature at which the configurational entropy first becomes zero as we cool the polymer–diluent…
The results are given of comprehensive measurements on the magnetic and crystallographic properties of the ferromagnetic Heusler alloys Cu2MnAl, Cu2MnIn, Cu2MnSn, Cu2MnGe, Au2MnAl, and the antiferromagnetic alloy Cu2MnSb. The alloys Cu2MnBi and Cu2MnGa are polyphase and the ferromagnetism may be due to binary phases p…

The feeding of 6 copepods ( Calanus finmarchicus, Acartia tonsa, Centropages hamatus, C. typicus, Labidocera aestiva, and Tortanus discaudatus ) was examined with 3 different foods—a) diatoms ( Thalassiosira fluviatilis ) alone, b) diatoms plus Artemia nauplii, and c) Artemia alone—and compared with the structure of t…
In paramagnetic aromatic systems the relation between the hyperfine coupling constants a H for the protons and the spin density ρ on the adjacent carbon atom is usually given by the relation a H = -Qρ (McConnell) in which Q is a constant characteristic for the C-H bond. In the paramagnetic ions of aromatic molecules t…
The collision of plates at high velocity sometimes causes them to be metallurgically bonded. A study has been made of the nature of the bonds and of the conditions required to produce bonding. A necessary requirement is the formation of a jet in the space ahead of the region of impact. When the collision region moves…
Abstract The magnetic anomalies in vertical, horizontal, and total intensity for the thin infinite dike are shown to belong to a single mathematical family of curves for all values of dip and strike of the dike and all values of inclination of the magnetizing field. The complete family of standard curves has been cons…
