    Notes: Recombination coefficients of hydrogen have been modeled respectively for the front side and the back side of plasma facing materials. On the front side, both the normal-surface sites and the imperfection-surface sites produced by the energetic ions are taken into account, and the dependence of the aerial density of active recombination sites upon the aerial density of imperfections and the balance between the chemisorption and desorption of impurity atoms at imperfections are discussed. On the back side, the effective recombination coefficient is obtained by analyzing the metal-oxide system. This parameter depends upon the solution energy for the metal and the chemisorption energy on the oxide-layer surface as well as surface coverage, if it is rate-limited by the recombination in the oxide layer; and it increases with increasing diffusion coefficient and decreasing thickness, if it is rate-limited by diffusion in the oxide layer.

    Properties of hydrogenated amorphous silicon prepared by alternatively repeating chemical-vapor deposition from disilane and hydrogen plasma treatment (1993)

    Notes: Experimental studies have been carried out to characterize hydrogenated amorphous silicon prepared by alternatively repeating chemical-vapor deposition (CVD) from disilane and hydrogen plasma (HP) treatment (referred to as HP treated CVD a-Si:H). It has been found that hydrogen plasma treatment induces structural relaxation of Si network in addition to the passivation of Si dangling bonds. Two types of defect states with different Gaussian energy distribution exist in this material, and this type of distribution has been found to be common in undoped a-Si:H prepared by a variety of methods. High film quality, i.e., a low defect density (〈1016 cm−3) and a fairly long ambipolar diffusion length (0.12 μm), and significant reduction of light-induced changes have been simultaneously achieved in HP treated CVD a-Si:H. Steady state transport of electrons and holes under illumination are controlled by the states other than neutral Si dangling bond state (D0). The behavior of these states with long exposure to light is different from that of D0.

    Colposcopic assessment of stage I cervical cancer (1991)

    Notes: A differential assessment by colposcopy of three subgroups of stage I in the new FIGO classification of cervical cancer was attempted. Colposcopic findings in invasive cancer were atypical white epithelium, atypical mosaic, papillary punctation, atypical vessels, abnormal ‘rock-like’ projection, papillomatous growth and ulcer. Ulcer and abnormal ‘rock-like’ projection were more suggestive of a frank invasive carcinoma than a microinvasive carcinoma. While 89% of the cases in stage Ib were correctly predicted, only about 50% of those in stage Ia were correctly predicted. We propose that a colposcopic assessment be included in the armamentarium to decide the method of treatment for cervical cancer patients.

    A monoclonal antibody cross-reactive with three salmonid herpesviruses (1993)

    Notes: Abstract. A monoclonal antibody cross-reactive with strain H-83 Oncorhynchus masou virus (OMV) and Herpesvirus salmonis has been prepared. Western blot analysis revealed that the monoclonal antibody, designated clo. 7, recognized the 16 000 (16K)-polypeptide of these herpesviruses but not the polypeptides of infectious pancreatic necrosis virus or infectious haematopoietic necrosis virus. Clo. 7 showed neither neutralizing activity against strain H-83 nor cytotoxicity to strain H-83-infected RTG-2 cells in the presence of complement. The purified antigen, recognized by clo. 7, from strain H-83 was a polypeptide with a molecular weight of 16K, and sensitive to proteolytic enzymes and sodium periodate, but not to neuraminidase and ethylether. The antigen was heat stable and stable at pH 5·0 – 9·0.

    Deep defect states in hydrogenated amorphous silicon studied by a constant photocurrent method (1992)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Experimental studies by means of a constant photocurrent method (CPM) have been carried out on the deep defect states in undoped hydrogenated amorphous silicon (a-Si:H). Assuming Gaussian energy distributions, two types of defect states (ST1 and ST2) have been found from careful analysis of CPM spectra; one of these states (ST1) is a neutral Si dangling-bond (Si D0) state, and the other (ST2) is a negatively charged dangling-bond-like defect state located in the lower gap. ST2 lies deeper in energy by 0.1 eV, and has a narrower full width at half-maximum (FWHM) when compared with ST1. Possible candidates for ST2 have been discussed by referring to the previous models of defects in a-Si:H. The FWHM of ST1 (the Si D0 state) does not always depend on the overall structural disorder estimated from Raman spectra. The energy position of the Si D0 state measured from the valence-band edge is almost independent of the optical band gap. Long exposure to light increases the density of ST1 (the Si D0 state) and decreases that of ST2, which suggests that defect conversion proceeds during the illumination.

    Properties of plasma-deposited hydrogenated amorphous silicon prepared under visible light illumination (1990)

    Notes: Properties of hydrogenated amorphous silicon (a-Si:H) prepared by glow discharge decomposition of silane with visible light illumination on a growing surface have been described. The visible light illumination during growth has resulted in smaller light-induced changes, slightly lower photoconductivity before the prolonged illumination, lower content of bonded hydrogen, and lower ratio of the number of silicon dihydrides to that of total silicon-hydrogen bonds. Formation of Si network and consequent structural disorder of SiSi bonds, on the other hand, has not been affected by the illumination during the growth. The improved stability against the long exposure to light can be ascribed to the lower bonded hydrogen content and the reduced density of SiH2 bonds, while the structural disorder of the Si network does not have a direct relationship with the light-induced changes.

    The Evidence of Carotid Body in the Carotid Rete of the Shiba Goat (1994)

    Notes: The carotid body was found in/on the cavernous sinus of the carotid rete of the Japanese miniature Shiba goat by light and electron microscopies. The carotid body-like aggregated cell group consisted of two types of cells arranged in the lobule. The first type contained membrane-bound granular vesicles; these cells resembled to the type-I cells in the carotid body. The second type contained no cytoplasmic vesicles, and were located in the periphery, investing the type-I cells. These features appear to be consistent with those of the type-II cells in the carotid body. The nerve ending showed two peculiar features in the intercellular space of type-I cells. The clear vesicle-containing nerve ending showed a structural feature indicative of efferent synapsis. The small granular vesicle-containing nerve ending has been described as a baroreceptor-like ending by VERNA (1979). All of these features are typical characteristics of the carotid body.

    Ultrastructure of wound healing following direct pulp capping with calcium-β-glycerophosphate (Ca-BGP) (1993)

    Notes: Tissue changes in rat incisors after direct pulp capping with calcium-β-glycerophosphate (Ca-BGP) have been studied using light and electron microscopy. Immediately after pulp capping, Ca-BGP was converted to hydroxyapatite (HAP) at the cavity floor. At Day 1, the exposure site was covered with Ca-BGP-mediated mineralized tissue. Osteodentine had developed below this mineralized tissue at Day 3. Matrix vesicles (MV) were observed in the extracellular matrix between large cells and osteodentine. At Day 5, tubular dentine was observed below the osteodentine. Three days after the application of Ca(OH), in a control experiment, osteodentine had formed below the necrotic zone; however, tubular dentine was not observed at Day 5. These findings suggest that the applied Ca-BGP might be the source of Ca and inorganic phosphate (Pi) through hydrolysis by alkaline phosphatase (ALP), and that Ca-BGP-mediated mineralized tissue induces the early formation of tubular dentine.
