    Notes: By numerical calculation, it is shown that vortices are sequentially generated on the background charged layer forming parallel shear flows in a two-dimensional low beta incompressible plasma when the charged layer is locally disturbed by a small amount of additional charge. Numerical experiments are performed in a rectangular domain with 0〈x〈Lx and −Ly/2〈y〈Ly/2 and the background charged layers are distributed to form the plasma flow U in the x direction with a velocity shear of ∂U/∂y≠0. The boundaries at x=0 and Lx are to supply plasmas identical to the background plasma initially loaded inside the domain. The plasma particles reaching the boundaries are freely allowed to leave the experimental domain. A vortex (named the mother vortex) first develops the local charge disturbance initially given, and subsequently new vortices (named the daughter vortices) are generated on the charged layer. This can be thought of as a result of propagation of the initial disturbance: A relative plasma flow as seen from the mother vortex can carry downstream the disturbances originating from the vortex, which can trigger growth of the daughter vortex. The numerical experiments in our nonperiodic system show that the intervals between the vortices are relatively close to the wavelength of the most unstable mode predicted by the linear analysis for periodic vortices. It is also shown that the temporal growth rate γ of the vortex in its early growing period is comparable to the corresponding linear growth rate of the unstable periodic vortices with the same wavelength.

    Genetic variants of protease inhibitors against fungal protease and α-chymotrypsin from hemolymph of the silkworm, Bombyx mori (1984)

    Notes: Abstract Many electrophoretic variants of hemolymph inhibitors of proteases from Aspergillus mellus and pancreatic α-chymotrypsin were found using 126 silkworm strains. Six inhibitors of the fungal protease were detected and eight of chymotryspin; the distribution of inhibitors among Japanese, Chinese, and European races was investigated. Comparison of electrophoretic patterns from F1 hybrids and parents showed that the offspring produce inhibitors of both parental types. Segregation in F2 and backcrossing suggest that the expression of each inhibitor is controlled in most cases by a pair of alleles which are responsible for strong and null bands. Two bands of fungal protease inhibitors C and D were controlled by codominant alleles. These results suggest that polymorphism of hemolymph protease inhibitors in the silkworm would be a useful experimental system for the study of the genetic control of protease inhibitors.

    Fatigue growth threshold of small cracks (1981)

    Description / Table of Contents: Résumé On analyse d'une manière théorique et d'une manière expérimentale les effets de la taille du grain et de la longueur d'une fissure sur la condition critique de croissance par fatigue de petites fissures. Le modèle théorique est basé sur l'hypothèse que la condition critique est déterminée par la condition suivant laquelle une bande de glissement à l'extrémité de la fissure bloquée par une limite de grain se propage dans un grain adjacent ou non. En comparant le modèle analytique avec des essais sur de l'acier doux, on a trouvé que la contrainte critique estimée pour la limite de fatigue dans le cas d'éprouvettes sans entaille fournissait la composante effective de la contrainte appliquée. Lorsque la contrainte critique ramenée à la limite de fatigue d'éprouvettes sans entaille a été corrélée avec la longueur de fissure correspondante ramenée à une certaine longueur de fissure, la relation théorique a été trouvée en bon accord avec des données expérimentales. D'une analyse complémentaire des données publiées dans le cas de matériaux divers, on a trouvé que la relation théorique standard donnait une limite inférieure des valeurs critiques de la contrainte et du facteur d'intensité des contraintes. Une déviation par rapport à la relation théorique a été trouvée dans le cas de matériaux durs; cette déviation est expliquée par une extension du modèle, en considérant que des métaux durs comportent des défauts initiaux inhérent à la structure même dans le cas d'éprouvettes sans entaille.
    Notes: Abstract The effects of grain size and crack length on the threshold condition of fatigue growth of small cracks are analysed both theoretically and experimentally. The theoretical model is based on the assumption that the threshold condition is determined by whether the crack-tip slip band blocked by the grain boundary propagates into an adjacent grain or not. By comparing the model analysis with the experiments of mild steel, it was found that the threshold stress estimated from the fatigue limit of the smooth specimen gave the effective components of the applied stress. When the threshold stress normalized by the fatigue limit of the smooth specimen was correlated to the crack length normalized by a certain crack length, the theoretical relation was found to agree well with the experimental data. From a further analysis of the published data of various materials, the theoretical normalized relation was found to give a lower bound of the threshold values of the stress and the stress intensity factor. A deviation from the theoretical relation seen in the cases of hard metals was explained through an extension of the model by regarding that hard metals contained initial, inherent flaws even in the smooth specimen.

    Notes: Abstract Mercaptotropone was synthesized from tropone, and its acid dissociation constant (Ka) and distribution coefficient (KD) between benze and aqueous solution were spectrophotometrically determined as 5.75 (pKa) and 2.46 (log KD); Extraction behaviour of Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Pb(II), Cr(III), Fe(III), Y(III), and Zr(IV) with this reagent into benzene was examined. Cu(II) and Fe(III) were completely extracted from acidic solution, Mn(II), Co(II), Ni(II), Zn(II), Pb(II), and Zr(IV) were also extracted from intermediate pH region, a part of Cr(III) was extracted, but Y(III) was not extracted.
