    Notes: Limiting molar conductances of the K+ and Cl− ions in heavy and light water have been determined at 5 °C as a function of pressure up to 1500 kgf cm−2 (1 kgf cm−2=0.9807×105 Pa) from the measured conductances and transference numbers of KCl. The residual friction coefficients (Δζ) are obtained for the cation and anion in D2O and H2O by using the determined limiting conductance and the bulk viscosity of solvent, and they are compared with the corresponding values predicted by applying the Hubbard–Onsager (HO) dielectric friction theory at various pressures below 1000 kgf cm−2. At atmospheric and high pressures, the solvent isotope and temperature effects on Δζ observed for the K+ ion are qualitatively in agreement with the theoretical prediction. However, the slightly positive pressure coefficients of Δζ(K+) are obtained in both solvents at 5 °C contrary to the theoretical prediction. Furthermore, Δζ(K+) in D2O at 5 °C is smaller than the theoretical one. These results suggest that another mechanism such as the passing through cavities one plays a more important role in ion migration of the K+ ion at lower temperatures and in D2O. On the other hand, the reverse solvent isotope and temperature effects on Δζ(Cl−), and the negative values of Δζ(Cl−) are found. These anomalies cannot be explained by the continuum theory.

    Notes: Limiting molar conductances of the K+ and Cl− ions in heavy and light water have been determined at 25 °C as a function of pressure up to 2 kbar from the measured conductances and transference numbers of KCl. The residual friction coefficients (Δζ) are obtained for the cation and the anion in D2O and H2O by using the determined limiting conductance and the bulk viscosity of solvent and compared with the corresponding values predicted by applying the Hubbard–Onsager (HO) dielectric friction theory at various pressures below 1 kbar. At atmospheric and high pressures Δζ of the K+ ion in D2O is larger than that in H2O just as predicted by the HO theory, but Δζ of the Cl− ion in D2O is smaller than that in H2O on the contrary to the theoretical prediction. The reverse solvent isotope effect on Δζ(Cl−) suggests that a microscopic viscosity in the vicinity of the relatively large ion is smaller than the bulk viscosity used in the continuum theory.

    Notes: Abstract DNA polymorphism patterns linked to the βA-globin gene were analyzed in healthy Japanese using four different restriction endonucleases. The chromosomes with the βA-globin gene were mapped through an evaluation of the presence of seven different restriction sites (HincII 5′ to ε; HindIII in Gγ and Aγ; HincII in, and 3′ to, ψβ1; AvaII in β; Bam-HI 3′ to β). Among 36 chromosomes analyzed, 20 chromosomes had a haplotype of [+−−−−−+]. Among 55 individuals examined, 7 possessed a homozygous haplotye of [+−−−−−+]. All Japanese with the AγT-globin gene had a subhaplotype of [−++−+] 5′ to the δ-globin gene. Their major haplotypes were [−++−+−+] and [−++−++−]. It was expected that the presence of the AγT-globin gene in Japanese may be deduced from subhaplotypes 5′ to the δ-globin gene.

    On one pion exchange potential with quark exchange in the resonating group method (1985)

    Notes: Abstract The effect of quark exchange between different nucleons on the one pion exchange potential is studied in the framework of the resonating group method. The calculated phase shifts including the one pion exchange potential with quark exchange in addition to the one gluon plusσ meson exchange are shown to be consistent with experiments. Especially thep-wave phase shifts are improved by taking into account the quark exchange on the one pion exchange potential.

    Notes: Abstract Expectation values of the total spinS of nucleons in nuclei are very quenched. This quenching is shown to be hardly explained by the mixture ofΔ-hole states. The quenching thus provides the best evidence for the role of non-central parts of the nucleon-nucleon interaction, especially the tensor interaction.

    Immobilization of cellulolytic and hemicellulolytic enzymes on inorganic supports (1987)

    Notes: Commercial cellulase preparations from Trichoderma viride and Aspergillus niger were immobilized on porous silica glass and ceramics such as alumina and titania with titanium tetrachloride (TiCl4) and on their silanized derivatives with glutaraldehyde (GLUT). The amounts of the immobilized enzymes were in the range 10-50 mg/g carrier (dry) depending on the kind of carrier and immobilization method. Their activities toward carboxymethyl cellulose (CMC), xylan, aryl-β-glucoside, and aryl-β-xyloside were 3-53% of those of the native enzymes. The optimum pH of the enzymes shifted to the acidic side in most cases, whereas the optimum temperatures were nearly the same as those of native ones. The activity of immobilized enzyme preparations towards CMC did not change significantly during continuous operation over a periods of 60 days. Finally, xylan was hydrolyzed with the immobilized enzymes, and the sugars formed were investigated.

    Some propositions on caustics and an application to the biaxial-fracture problem (1985)

    Notes: Abstract Some fundamental problems on the optical method of caustics, which is used to determine the value of the stress-intensity factor, are studied. The paper shows that the radiusr o of the initial curve considerably affects the results and describes a method to eliminate this effect. This method is also applied to the biaxial-stress fracture problem. It is shown that the biaxial stress affects the fracture toughness of thin specimens of Plexiglas sheets and that the fatigue-crack-growth rate is increased due to the compressive stress along the crack line.
