    Shift of surface Fermi level position toward the conduction band minimum by crystal defects near GaAs(001) surface (1997)

    Notes: The effects of crystal defects near the surface on the position of surface Fermi level (EFS) are investigated using photoluminescence (PL) measurements and synchrotron radiation photoelectron spectroscopy (SRPES). For the lightly Si-doped GaAs(001) surface, PL measurements reveal that after heating to 500 °C a layer with lower PL peak intensities related to gallium vacancies than those of the bulk exists just under the thermal degraded layer. SRPES shows that EFS moves upward to 1.1–1.17 eV above the valence band maximum when this thermal degraded layer is removed by chemical etching and the excess arsenic on the surface, which is formed by rinsing the etched surface with deoxygenated and deionized water, is evaporated by heating in ultrahigh vacuum (UHV). After evaporation of excess arsenic on the surface by heating, the etching-depth dependence of EFS for a sample preheated in UHV correlated with the existence of this defect concentration layer. These results suggest that the position of EFS for the GaAs(001) surface is strongly influenced by crystal defects near the surface. © 1997 American Institute of Physics.

    Discharge frequency dependence of particulate growth in high frequency silane plasmas (1995)

    Notes: Discharge frequency dependence of growth of particulates is studied in high frequency silane plasmas. Particulates appear earlier after discharge initiation and the increasing rate of their amount in the subsequent phase decreases with increasing the discharge frequency from 3.5 to 28 MHz. Even in the early phase of their formation for all 3.5–28 MHz discharges, particulates grow principally around the plasma/sheath boundary near the powered electrode, where short lifetime radicals are actively generated. For 28 MHz, the density of particulates in the early discharge phase is extremely high (≥1011 cm3). The latter two features suggest that many short lifetime neutral radicals (such as SiH2), being produced at a high rate, significantly contribute to the nucleation and initial growth of one particulate, at least, for a relatively high power density of the order of 0.5 W/cm2. © 1995 American Institute of Physics.

    Notes: Leakage current through epitaxial BaTiO3 films was investigated to clarify the difference between the characteristics of nanometer and millimeter-size metal contacts. SrTiO3:Nb bottom electrode revealed genuine properties of a single metal/BaTiO3 contact and demonstrated that breakdown voltage and leakage current density at both nanometer and millimeter-size contacts were controlled by the Schottky barrier. However, in marked contrast with millimeter-size contacts, nanometer-size contacts conducted little current below breakdown voltage and repeatedly exhibited abrupt breakdowns having a giant current density 〉10 A mm−2. The breakdown field was as high as 0.45 MV cm−1 at the forward bias, while no breakdown occurred up to 0.5 MV cm−1 at the reverse bias. © 1998 American Institute of Physics.

    Notes: We report in vivo laser computed tomographic images of the proximal interphalangeal joint region of a healthy human volunteer's index finger. The laser computed tomographic (CT) images were obtained with a highly sensitive coherent detection imaging method that is based on the optical heterodyne detection method. These laser CT images are compared at the wavelengths of 715 nm and 1.064 μm and with images obtained by conventional imaging methods such as x-ray CT and magnetic resonance imaging. Internal structures of the proximal interphalangeal joint region could be clearly identified in the laser CT images. © 1996 American Institute of Physics.

    Feeding and growth of early juvenile Japanese sardines in the Pacific waters off central Japan (1998)

    Notes: Larval and early juvenile growth was backcalculated for individual Japanese sardines Sardinops melanostictus using the biological intercept method based on the allometric relationship between otolith radii and fish lengths. Sardines grew at 0·81 mm day−1 during the larval stage. In the early juvenile stage, they grew from 32·3 to 45·4 mm fork length (L) over a 20-day period (0·64mm day−1). Using the observed relationship between L and wet body weight (W), W = 0·00942 L2.99, W of the sardine juveniles was calculated to increase from 306 to 832 mg during the 20-day period. The carbon (C) requirement to achieve this growth in weight was estimated to increase from 5·7 to 9·6 mg day−1. Stomach contents of the sardines were composed mostly of copepods (73%) and larvaceans (25%). Wet stomach content weight (Ws) was expressed by a power function of the W, Ws=0·731 W0·658. Carbon and nitrogen constituted 41·7 ± 1·5 and 10·0 ± 0·4% of the dry Ws, respectively. Stomach C content increased from 2·0 to 3·9 mg during the 20-day period. Three to four cycles of the daily turnover of stomach contents during the 16 h of daytime, corresponding to a gastric evacuation rate of 0·2–0·3 h−1 under continuous feeding, met the C requirement to achieve the backcalculated growth in early juvenile sardines. The Kuroshio frontal waters seem to provide Japanese sardine juveniles with favourable growth conditions.

    Effect of Maternal Antigenic Stimulation on the Active Immune Responses of Their Offspring (1984)

    Notes: Pregnant mice were stimulated by heterologous erythrocyte and protein antigen, and the active immune responses of their offspring as measured by plaque-forming cells (PFC) were investigated. In offspring derived from mothers immunized by a suitable amount of T-dependent antigen, clear-cut suppression of development of specific PFC in spleen was observed over a significant period after delivery. The mechanism of this suppression was investigated, and the following results were obtained. When the heterologous erythrocyte was used as antigen, the more the specific PFC developed in the mother spleen, the stronger the suppression of PFC observed in their offspring. However, it is worthy of note that passive administration of antibody to pregnant mice did not induce suppression in their young. In case of the protein antigen ovalbumin (OVA), pregnant mice had to be injected with a suitable amount of antigen, along with aluminium hydroxide, for either primary or secondary stimulus to induce the suppression of specific PFC in their offspring. Soluble OVA administered to pregnant mice was not effective for inducing suppression in the offspring. Based on these results, some possible mechanisms are discussed concerning specific PFC suppression in the offspring when pregnant mice are stimulated.

    DISTRIBUTION AND ANTI-INFLAMMATORY EFFECT OF MESALAZINE ON CARRAGEENAN-INDUCED COLITIS IN THE RABBIT (1996)

    Notes: 1. A controlled-release preparation of mesalazine microgranules (PentasaR; Ferring AS, Vanlose, Denmark) releases the active ingredient over a wide area from the small intestine to the rectum and is consequently expected to bring about therapeutic benefits to patients with ulcerative colitis and Crohn's disease.2. Mesalazine microgranules (50 or 150 mg/kg per day) were administered orally to each rabbit with carrageenan-induced colitis for six weeks. Its inhibitory effect on colonic mucosal damage was assessed in terms of the microscopic damage scores, leukotriene B4 concentrations and concentrations of mesalazine derivatives.3. At the end of the experiment, the mesalazine 150 mg group had gained a significantly greater bodyweight than the control group. Microscopic damage was significantly lower in the 150 mg group than in the untreated control group. Tissue concentrations of 5-aminosalicylic acid and acetyl-5-aminosalicylic acid in the small and large intestine were higher in the 150 mg group than in the 50 mg group. Mucosal leukotriene B4 levels tended to be lower in rabbits receiving the larger dose of mesalazine.4. The present study indicates that slow release 5-aminosalicylic acid at the larger dose reaches the large bowel in sufficiently high concentrations following oral administration and significantly reduces carrageenan-induced colitis in the rabbit.
