    The ability of Climacodon septentrionalis to immobilize and kill a mycophagous nematode (Aphelenchoides sp.) in vitro is described for the first time. Two isolates produced droplets (20–45 μm in diameter) that formed at the apices of tall, stalked, and branching secretory cells (700–1,500 μm tall). On 2% modified malt extract agar, nematodes became enveloped in the droplets, which restricted their ability to move and resulted in complete immobilization and death within several hours of contact. The rate of decomposition of the nematodes varied considerably, with most individuals persisting for weeks whereas others were degraded within several days and appeared to be colonized by dense hyphal growth. This study provides the first documentation of a non-agaricoid fungus producing secretory cells that are able to immobilize nematodes.

    This paper presents a review for the crystallization of nonlinear optical crystals such as
    LaBGeO5
    ,
    LiBGeO4
    , fresnoite-type
    Ba2TiGe2O8
    and several langasite-type crystals in glasses and for the second order optical nonlinearities of those crystals. In this study, transparent surface crystallized glasses consisting of
    LaBGeO5
    ,
    LiBGeO4
    and
    Ba2TiGe2O8
    crystals were successfully fabricated from the corresponding glasses. Second order nonlinear optical coefficients, d33, were evaluated by Maker fringe technique for those surface crystallized glasses. As a result, it was demonstrated that the
    LiBGeO4
    and the
    Ba2TiGe2O8
    crystals indicated large d33 values, i.

    Ba2TiGe2O8
    crystal is comparable to that of LiNbO3 single crystal. Moreover, we confirmed for the first time that the langasite-type crystals, which are promising materials for SAW device, are formed by crystallization in the corresponding glasses.

    The bioavailability (

    BA
    ) of
    E
    3810, an unstable compound in acid, was studeid by controlling gastric pH in beagle dogs. The BAs, after the administration of
    E
    3810 solution orally to dogs with a low or a high gastric pH, were 3.16 ± 1.28% and 76.
    4
    ± 13.8%, respectively. These results suggested that
    E
    3810 decomposes rapidly in the presence of gastric acid, but its
    BA
    is high if the decomposition of
    E
    3810 is avoided in the gastrointestinal tract. To establish a dosage form of
    E
    3810 for toxicity testing in the dog,
    E
    3810 enteric-coated tablets (ϕ=6.
    5
    mm) and
    E
    3810 solution were administered. The tmax after the administration of
    E
    3810 enteric-coated tablets was prolonged (tmax=
    5
    .42 hr), suggesting a slow gastric emptying, or a delay in the release of
    E
    3810. In contrast, when the tablets were asministered orally to fasted beagle dogs, tmax was obtained within 1 hr, suggesting rapid release once the tablet left the stomach. After administration of
    E
    3810 solution to beagle dogs with a high gastric pH, the
    BA
    was high, with the lowest variability. In the preliminary toxicity test,
    E
    3810 solution was administered to dogs with a high gastric pH once a day for seven days. The plasma concentrations of
    E
    3810 on day 1 and day
    7
    increased dose-dependently, and there is no difference in pharmacokinetics between day 1 and day
    7
    . These results indicate that the method to control gastric pH in dogs is useful for the dosing of a compound that is unstable in gastric acid.

    One method currently being considered for the disposal of high level radio-active waste is burial in the seabed. When a hot object is buried in soil, the temperature of the soil adjacent to the object is raised and there is transient heat flow away from the object. The rise in the temperature of the soil causes excess pore pressures to be generated and transient pore water diffusion also takes place. A finite element formulation of the coupled heat flow and consolidation problem is presented. The computer implementation of this formulation is found to compare favourably with analytical solutions based on the same physical principles.

    The possibility of attenuation of microseismic waves due to the presence of an upward folding of the ocean bottom into the liquid is discussed in this paper. The upward folding of the ocean bottom has been idealized by means of an irregularity in the form of a rectangle intruding into the liquid and the evaluation of the displacement component at any point of the solid medium has been carried out in two stages. First, the change in the incident mode of the surface wave due to the presence of the rectangular irregularity has been determined, and second, the subsequent change of the resulting displacement components due to the termination of the liquid layer and the step change in elevation of the solid medium at the continental margin has been discovered. Finally, numerical calculation has been made to determine the attenuation of the microseismic waves of different periods due to the presence of the rectangular irregularity at the ocean bottom.

    In the first part of the present work the interaction of glycophorin with dimyristoylphosphatidylcholine (DMPC) is studied by freeze fracture electron microscopy, densitometry, calorimetry, and 90° static light scattering. An exothermic lipid/protein interaction energy of WP=190 kJ•mol-1 was found by application of the well known Van Laar relation for the displacement of the freezing point and the Gibbs-Duhem relationship. Secondly, the effects of Ca2+ on the lipid/protein interaction were studied. Following Ca2+ addition a remarkable decoupling of the interaction of the glycophorin head group with the bilayer surface was revealed by densitometry and gold-labeling electron microscopy. It is estimated that about 80% of lipid once disturbed by the adsorption of glycophorin head groups is decoupled after addition of Ca2+. Thirdly, the selective interaction of glycophorin with binary lipid mixtures was studied, including the mixtures of DMPC with dimyristoylphosphatidylserine (DMPS) and dilauroylphosphatidylcholine (DLPC), and the mixture of dipalmitoylphosphatidylcholine (DPPC) with DLPC.
