A state of the art review of nonsilica based infrared fibers is presented. Two types of fiber materials have been investigated--crystals and glasses. Crystal fiber work appears to be focused on development of short haul CO/sub 2/ laser power delivering lines at 10.6 µm. The maximum delivering power of the CW CO/sub 2/…

Point has suggested that during the polymer crystallization process, individual stems form by zippering of monomer segments onto the substrate and that at any time during the zippering process the stem can fold over, thus initiating a new stem. We augment the treatment of Point analytically by allowing each of the sub…
The strength of sintered silicon nitride was measured by three‐point bending, four‐point bending, and expanded‐ring tests at room temperature. The data obtained were analyzed using Weibull statistics. The results indicate that effective volume is the major factor determining strength.

The domain structure changes occurring during magnetization of a (110) oriented disc of Tb0·27 Dy0·73 Fe2 have been studied by synchrotron X-radiation topography. Despite there being two easy directions in the specimen surface, the commonest demagnetized configuration consisted of 71° walls on (001) between domains ma…

Potentiostatic studies in 0.5M sodium chloride solution show that an arsenic addition to the alloy is only effective in preventing dealloying of α‐brass at potentials more noble than 0.0V on the hydrogen scale. This potential coincides with that potential at which arsenic in the alloy can be oxidized to soluble arseni…
Abstract Fluorine doped silica samples have been investigated by Raman spectroscopy. The results obtained allow us to propose a model for dopant incorporation in the silica network, involving the formation of SiO 3 F tetrahedron. A relationship between the intensity of the ν(Si‐F) stretching vibration band and the ref…
X-ray diffraction studies on samples of 4′-Pentyloxy-4-Cyanobiphenyl and 4′-Octyloxy-4-Cyanobiphenyl over the entire mesomorphic range are reported in this paper. A magnetic field was used to align samples. The orientational distribution functions f(β) have been calculated from the angular distribution of X-ray intens…
Abstract The fracture behavior of human hair has been investigated with a view toward delineating fracture mechanisms that lead to different types of fracture under tensile loading. Principally, three types of fracture are encountered—smooth fractures, step fractures, and fractures involving undefined fibrillated ends…
The previously studied system GeO 2 ‐Bi 2 O 3 ‐TI 2 O was extended with the addition of PbO using air‐ and water‐quenched melted samples. Large areas of glass formation were found in the systems GeO 2 –Bi 2 O 3 –PbO and GeO 2 –PbO–Tl 2 O at all but the lowest GeO 2 contents. Glasses were examined by powder X‐ray diffr…
An attempt has been made to evaluate the optical gaps in Ge1-x S x and Ge k Sb m S n glassy systems using Manca's relation and the bond statistics of various models. The best agreement between calculated and experimental data is obtained for a chain-crossing model in the S-rich region and for a model due to Philipp in…

The signs of the Leslie viscosities α2 and α3 for nematics consisting of disk like molecules are discussed. It is predicted on theoretical grounds that for disk like molecules α3 is always positive while α2 should be able to exhibit both positive and negative values. This is the first time that the possibility of a po…
Abstract High‐density polyethylene was filled with chalk in various concentrations ranging from 10% to 60% by weight. Ethylene oxide oligomer M w = 300 was used as a liquid modifier for chalk in the amount 0 ÷ 20 wt % of the filler. The mechanical properties of these composites showed that high density polyethylene fi…
