    Effect of cumulative ablation on the ejection of particulates and molecular species from YBa2Cu3O7−x targets (1995)

    Notes: Effects of cumulative ablation on the ejection of particulates and molecular species in pulsed-laser deposition are studied by Mie scattering and laser-induced fluorescence spectroscopy, respectively. When a fresh target is ablated, a large amount of particulates are ejected during several initial shots and rapidly decreased within the first ten shots of ablation. This is due to the ejection of powder residues which are struck on the target surface during the polishing process. After this period, ejection of particulates increased gradually and almost saturated after 200 shots. The saturation characteristic is empirically formulated as a function of the number of cumulative ablations. On the other hand, ejection of molecular species rapidly decreases during the initial 500 ablations and afterwards decreases more slowly with further ablation. The effects of cumulative ablation on the particle ejection are discussed in conjunction with the structural modification of the ablated surface observed by the scanning electron microscope. © 1995 American Institute of Physics.

    Notes: The specification and the layout of the booster synchrotron for SPring-8 were decided. The synchrotron is designed to accelerate electron or positron beams from 1 to 8 GeV with a repetition cycle of 1 Hz. The construction of the synchrotron was started in 1993. First, one bending, one quadrupole, and one sextupole magnet were made and the results of the magnetic field measurement were acquired. Two septum, one bump, and one kicker magnets for the beam extraction have been made, the field measurement and a few improvements have progressed. The high power test of the first rf cavity was finished successfully. The calibration test of the button position monitor with the signal treatment circuits is advanced now. The residual components of the synchrotron are designed and constructed, and the commissioning of the synchrotron will start in 1996. This paper presents the first measurement of each component. © 1995 American Institute of Physics.

    Notes: Fe nanocrystalline films were prepared by the gas-deposition method (GDM). The films were composed of small particles and their aggregates. With an increase of pressure difference between an evaporation chamber and a deposition chamber, the grain size is slightly reduced and lower coercivity is realized. The Mössbauer spectra consisted of a crystalline component (α-Fe) and a boundary component with a hyperfine field of 310 kOe; no oxide subspectrum was observed. Magnetizations of the samples are around 95% of that of bulk α-Fe. Fe nanocrystals prepared by GDM are found to show good oxidization resistance. © 1997 American Institute of Physics.

    Notes: A specific angular distribution of x rays from 111In embedded in a thin-film waveguide (Au film/Langmuir–Blodgett film/Au substrate) is observed by a non-energy-dispersive two-dimensional detector (imaging plate). The angular distribution for the thickness of the upper Au layer of 90 A(ring) can be explained by normal calculation of the optical electromagnetic wave solution of Maxwell's equations for each interface and reciprocity. However, the angular pattern in the upper 400 A(ring) Au thickness layer cannot be accounted for by the normal approach without considering the intensity of the x-ray sheet beam emerging from the end of the multilayer. © 1995 American Institute of Physics.

    Notes: The junction capacitance for a carbonaceous thin-film/n-type silicon layer photovoltaic cell made by chemical vapor deposition of 2,5-dimethyl-p-benzoquinone on a silicon substrate at 500 °C was measured, and an energy band diagram for this junction was sought out. The result confirms that the carbonaceous thin-film/n-type silicon junction is a heterotype junction. Its junction barrier is about 0.54 eV. This junction shows a depletion layer of about 1.1 μm in thickness at zero bias voltage, and most all of which was established in the silicon substrate. A work function of about 5.0 eV for the carbonaceous film was estimated based on the energy-band diagram of this junction. © 1996 American Institute of Physics.

    Notes: A photovoltaic cell with carbonaceous thin film/n-type silicon (C/n-Si) was fabricated utilizing a process in which a carbonaceous thin film was deposited on an n-type silicon substrate by chemical-vapor deposition of 2,5-dimethyl-p-benzoquinone at 500 °C. Under illumination of 15 mW cm−2 light with wavelengths between 400 and 800 nm (xenon arc lamp), a power conversion efficiency (η) of 6.45% was achieved from this photovoltaic cell. This C/n-Si cell has shown a normalized short-circuit-current efficiency of more than 0.85 under illumination of 30 μW cm−2 monochromatic light from 500 to 950 nm. © 1996 American Institute of Physics.

    Notes: 1. Prostacyclin elicits potent vasodilation and inhibition of platelet aggregation through binding to its membrane receptor. The impairment of prostacyclin receptor activity is implicated in various human cardiovascular diseases. We recently succeeded in molecular cloning of cDNA for the mouse, rat, and human prostacyclin receptors.2. In the present study, we examined the mRNA expression of the prostacyclin receptor in various rat tissues, and further investigated its gene expression in the hypertrophied cardiac ventricles of stroke-prone spontaneously hypertensive rats (SHRSP).3. In rat tissues, a single RNA band of approximately 3.7 kb was detected by northern blotting analysis using rat prostacyclin receptor cDNA as a probe. In adult Wistar rats, abundant mRNA expression was observed in the aorta, lung and spleen. Substantial amounts of transcript were expressed in the heart, pancreas, thymus and stomach. In contrast, no mRNA expression was detected in the brain.4. We further examined the mRNA expression of the prostacyclin receptor in the ventricles of 21 week old SHRSP. The ventricles of SHRSP showed remarkable hypertrophy, compared with those of age-matched Wistar-Kyoto (WKY) rats. The expression of prostacyclin receptor mRNA in the hypertrophied ventricles of SHRSP was almost equivalent to that in the ventricles of WKY.5. The present study revealed the gene expression of the prostacyclin receptor in various rat tissues, and further demonstrated the receptor mRNA expression in hypertensive cardiac hypertrophy. The present study will give a clue to investigate the clinical implication of prostacyclin and its receptor.

    Notes: 1. The effects of OKY-046, a specific thromboxane (TX) synthetase inhibitor, on blood pressure, urinary excretion of TX and its release from blood platelets and renal papilla, and pathological change of glomeruli were evaluated in Dahl salt-sensitive rats.2. Average daily intakes of OKY-046-treated rats were 0.93 mg/kg (low dose), 9.8mg/kg (moderate dose), and 88 mg/kg (high dose).3. Systolic blood pressure tended to decrease by 6.3, 11.4, and 10.9% in three OKY-treated groups.4. OKY-046 suppressed the release of TX from platelets in a dose-dependent fashion. Both TX in urine and released from renal papilla decreased in OKY-treated groups with moderate and high dose. OKY-046 resulted no change in urinary excretion or release from renal papilla of prostaglandin E2 or 6-keto-prostaglandin F1α.5. Glomerular sclerosis score decreased significantly in both groups treated with moderate and high doses of OKY-046.6. An inhibition of renal TX synthesis by TX synthetase inhibitor has a protective effect on the development of hypertensive renal damage with minor antihypertensive effect in Dahl salt-sensitive rats.

    Localization of an SLG protein expressed under the regulation of a tapetum-specific promoter in anthers of transgenic Brassica napus (1998)

    Notes: Abstract  S-locus glycoprotein (SLG) is known to be one of the proteins related to self-incompatibility in Brassica, and its transcripts are detected in anthers as well as stigmas. However, an SLG protein has not been detected in anthers so far. Because of sporophytic control of the self-incompatibility (SI) phenotype of pollen, an SLG gene is expected to be expressed in the sporophytic tissue of anthers, i.e., the tapetum. Overexpression of an SLG gene in the tapetum would enable us to predict the localization and function of an SLG protein in anthers. In this study, an SLG gene of self-incompatible B. campestris under the control of a tapetum-specific promoter was introduced into self-compatible B. napus. Immunoblot analysis using anti-SLG antiserum detected the exogenous SLG protein in the immature anthers, but not in the mature anthers. Immunoelectron microscopy showed the SLG protein to be localized in the tapetum and in the exine cell wall layer at the stage when the tapetum was degenerating. This result indicates the possible movement of the SLG protein from the tapetum to the pollen surface. A pollination test indicated that the pollen of the transgenic B. napus did not gain the SI phenotype.
