The first US case of human nanophyetiasis that does not involve ingestion of raw or undercooked salmonid fishes is reported. The patient worked with highly infected fish. Hand contamination with the infectious metacercariae of the digenetic trematode Nanophyetus salmincola (family Troglotrematidae) occurred during the…
Diffusion coefficients of hydrogen in the palladium films of α-phase have been measured between 278 and 323 K by an electrochemical stripping method. Palladium films were deposited on iron by RF sputtering. The values of the diffusion coefficient of hydrogen obtained for the film specimens 0.68 μm and 1.36 μm in thick…
Evolution equations are derived for the density function of a suspension sedimenting above a plane. The equations are in the form of a nonlinear conservation law and the solutions might develop jump discontinuities in a finite time. The analysis starts on a local microscopic level, and the averaged equations are obtai…

Article WEATHER INDUCED DEGRADATION OF LINEAR LOW DENSITY POLYETHYLENE (LLDPE): MECHANICAL PROPERTIES was published on January 1, 1990 in the journal Journal of Polymer Engineering (volume 9, issue 1).
Reaction of monolithiated-tetrathiafulvalene (TTF) has been used in the synthesis of amphiphilic TTF derivatives bearing long chains attached through carbon, silicon, sulphur, selenium, and tellurium atoms; the single crystal X-ray structure of the title compound is described.
In the preceding paper, a critical review of the state of knowledge of the bending behaviour of yarns and woven fabrics was reported. In the present one, an elastica-based computational model of plain-woven fabrics in pure bending is developed. The thread moment/curvature relation is considered to be linear. Various c…
In the preceding paper, an elastica-based computational model of the bending behaviour of plain-woven fabrics assuming linear bending behaviour of the constituent threads, together with appropriate computational techniques, was described. In the present paper, bilinear thread-bending behaviour, as proposed by Huang, i…
Incorporation of sterically encumbered aryl ligands permits the isolation and characterization of stable sodium and potassium tellurolates; X-ray structures of the monomers [Na(tmed)2][Te(2,4,6-Me3C6H2)] and [K(18-C-6)][Te(2,4,6-Pri3C6H2)] are described (tmed N,N,N′,N′-tetramethylethylenediamine; 18-C-6 1,4,7,10,13,16…
The effects of manganese and sulphur on the grain growth and texture development during isochronal annealing have been investigated for cold rolled 0.5% Si steel. Although both Mn and S affect the grain growth, its dependency on Mn content is influenced by the S level. In steels containing 0.004 to 0.017% S, an increa…
Presently available technology allows the construction of phase calibration equipment with phase resolutions of at least one part in 2/sup 18/, that is, a phase resolution of 0.00137 degrees . The users and the manufacturers of such equipment are faced with the practical problem of verifying their phase accuracy-both…
Abstract Die Verbindungen Sr 2 [Ga 2 S 5 ], Ba 2 [In 2 S 5 ] und Ba 2 [In 2 Se 5 ] wurden aus stöchiometrischen Gemischen der Elemente bei Temperaturen zwischen 1150°C und 1250°C dargestellt. Sie kristallisieren zueinander isotyp (Raumgruppe Pbca, Z = 8) mit den Gitterkonstanten Sr 2 Ga 2 S 5 a = 1252,3(6) pm, b = 120…
The chemical amplification concept proposed in 1982 to support high resolution short wavelength lithographic technologies that demand highly sensitive advanced resist systems is based on acid-catalyzed crosslinking, deprotection, and depolymerization reactions. Each approach has shown a tremendous progress. In this pa…
Abstract Dry synthetic polycrystalline salt (NaCl) has been deformed in uniaxial compression and in shear in order to gain insight into the influence of deformation mode on the development of crystallographic preferred orientation, microstructural evolution and mechanical behaviour (flow strength). The experiments wer…
A range of materials including sintered low and high coercivity ternary (NdFeB) and quarternary (NdFeBCo) magnet alloys and bonded Magnequench (MQI) was investigated. The effects of temperature including irreversible and reversible changes of magnetization are discussed. Magnets with two different working points were…
The machining performance of monolithic and composite silicon nitride and Al2O3-based cutting tools in continuous turning of Inconel 718 was examined. The character of tool wear has been found to vary, depending on the feed rate and cutting speeds. At a lower cutting speed, of 120 m/min, tool life is restricted by dep…
A previously undetected Bacillus subtilis aspartokinase isozyme, which we have called aspartokinase III, has been characterized. The new isozyme was most readily detected in extracts of cells grown with lysine, which repressed aspartokinase II and induced aspartokinase III, or in extracts of strain VS11, a mutant lack…

Velocity selection in two-dimensional dendritic growth caused by anisotropy of the surface energy is considered. In the limit of low anisotropy the integro-differential equation for the velocity spectrum is reduced to a differential equation. The solution of this equation, corresponding to the maximal velocity, is sta…
Paramagnetic point defects sensitive to the surrounding atmosphere were observed in ZnO powder. Changes in EPR lines following either thermal-vacuum treatment or contact with molecular O2 led to definite conclusions regarding the nature of the ZnO point defects and the electron-transfer processes active at the ZnO/O2…
