    Notes: Freeze-thawing studies at different concentrations, using an actomyosin solution (extracted from Alaska pollock), revealed that an 8% (w/v) solution of oligosaccharides mixture (HBOS) was most effective in cryoprotection. During frozen storage (-18°C), HBOS showed cryoprotective effects similar to sucrose and a sucrose+sorbitol mixture (1:1). Surimi gel prepared with HBOS showed higher hardness and more dense microstructure than others, although water holding capacity was slightly lower than the gel with sucrose+sorbitol. HBOS containing gel showed lower whiteness than sucrose but no difference with sucrose+sorbitol. HBOS appeared to have good potential as a non-sweet cryoprotectant of fish protein.

    Notes: Abstract In this study, porosity and graphitizability of coal tar pitch with the treatment pressure were investigated. 4-directional carbon/carbon composites (4D C/C) were made from the matrix precursor of coal tar pitch through the process of impregnation and carbonization. Then the effects of applied pressure during the densification on the composites were observed. The matrix pitch which had 600 bar applied during the carbonization process had one and a half times less pore area ratio than that treated at 1 bar. When the pitch was heat treated up to 2300°C after the high pressure carbonization, the degree of graphitization was improved on a small scale and the crystal size tended to reduce. As the applied pressures to 4D C/C composites increased from 1 to 600 bar, the densification ratio was greatly improved. In the pore size distribution of the 4D C/C composites, the macropore portion was decreased while the mesopore portion increased, when high pressures were applied.

    Surface energy and polarity of treated indium–tin–oxide anodes for polymer light-emitting diodes studied by contact-angle measurements (1999)

    Notes: We present contact-angle hysteresis and surface energy of differently treated indium–tin–oxide (ITO) thin films obtained from contact angles for liquids with different polar character. We find that the hysteresis and the polar and dispersion component of the surface energy depend strongly on the surface treatments. Oxygen-plasma treatments induce the highest polarity and the highest total surface energy, and we suggest that this improves the interface formation with polymers, and therefore, the performance of light-emitting diodes. We discuss the results in relation to the ITO surface roughness and chemical heterogeneity modified by the different treatments. © 1999 American Institute of Physics.

    Mixing enhancement via nozzle trailing edge modifications in a high speed rectangular jet (1999)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 11 (1999), S. 2731-2742

    ISSN: 1089-7666

    Topics: Physics
    Notes: An aspect ratio 3 rectangular nozzle with design Mach number 2 was used to investigate the effects of trailing edge modifications on mixing enhancement and to explore the sources of streamwise vorticity at the fully expanded jet Mach numbers 1.75, 2.0, and 2.5. The trailing edge modifications are simple cut-outs in the plane of the nozzle at the nozzle exit. The investigation of mixing and interaction between mixing layers and vortices was performed by the laser sheet illumination technique. Through surface flow visualizations and wall pressure measurements, the investigation of the major source of streamwise vorticity was carried out. In addition, the variation of thrust generated by the nozzle with modified trailing edges was investigated. In the underexpanded flow condition, the major source of streamwise vorticity was determined to be the spanwise surface pressure gradient on the modification. Substantial mixing enhancement was achieved in this flow regime. On the other hand, in the overexpanded flow regime, the role of streamwise vortices in mixing and the source of streamwise vorticity were unclear, and mixing enhancement was not substantial. No measurable thrust loss or gain was obtained for nozzles with trailing edge modifications, regardless of the type of modification. © 1999 American Institute of Physics.

    A matrix formalism for the Hall effect in multicarrier semiconductor systems (1999)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A matrix formalism for the Hall effect is presented for an arbitrary J-fold multicarrier semiconductor system. Explicit formulas are derived for important transport quantities such as the sheet resistance, the Hall coefficient, and the Hall scattering factor. For J≤3, these formulas reduce to simple closed-form expressions as a function of the applied magnetic field and the carrier densities and mobilities. The closed-form formulas are useful for the correct interpretation of the Hall effect in multicarrier semiconductor systems. The field dependence and asymptotic behavior of these formulas are also discussed.

    Inhibitory Effects of 150 Plant Extracts on Elastase Activity, and Their Anti-inflammatory Effects (1999)

    Notes: The inhibitory effects of 150 medicinal plants on elastase activity were investigated. Among the 150 plants, six plant extracts (final concentration 1 mg/ml in methanol) exhibited more than 65% of inhibition of elastase activity. The inhibitory effects of six active plants, including Areca catechu (IC50, 42.4 μg/ml), Cinnamonum cassia (IC50, 208.7 μg/ml), Myristica fragrans (IC50, 284.1 μg/ml), Curcuma longa (IC50, 398.4 μg/ml), Alpinia katsumadai (IC50, 465.7 μg/ml) and Dryopteris cassirrhizoma (IC50, 714.4 μg/ml) on the activity of human leukocyte elastase, hyaluronidase and lipid peroxidation were examined. In the lipid peroxidation assay, using the TBA method, three of the six plants, including Curcuma longa (IC50, 45.5 μg/ml), Areca catechu (IC50, 51.0 μg/ml) and Alpinia katsumadai (IC50, 116.3 μg/ml) exhibited more than 70% inhibition at the concentration of 1 μg/ml, but only one plant, Areca catechu (IC50, 563 μg/ml) showed high inhibitory effect on hyaluronidase activity. The results suggest that medicinal plants showing several biological activities may be potent inhibitors of the anti-ageing process in skin. This property might be useful for application in cosmetics.

    Determination of Panthenol, Cholecalciferol and Tocopherol in Cosmetic Products by Gas Chromatography-Mass Spectrometry in SIM Mode (1999)

    Notes: A novel simple method to detect vitamins in cosmetic products by gas chromatography-mass spectrometry (GC-MS) has been developed. Three vitamins (panthenol, cholecalciferol and tocopherol) were used for this study. Vitamins were prepared by dissolving in tetrahydrofuran (ThF), and silylated with bis-trimethylsilyltri-fluoroacetamide- trichloromethylsilane (BSTFA). Silylated vitamins were separated on a fused-silica capillary column coated with DB-5. The identification of each vitamin was accomplished by retention time and mass spectrum library search with a computer, and the quantitation was made in the selected-ion monitoring (SIM) mode of GC-MS. SIM mode had given sensitivity to determine 50 pg of panthenol, 285 pg of cholecalciferol and 130 pg of tocopherol. Linearity was maintained over the range 0.005–0.20% for each vitamin. Each cosmetic product (i.e. hair tonic and lotion) was found to contain amounts of the vitamins. This method was sensitive and gave 77.5–99.9% recovery of each vitamin from these cosmetic products. From these results, we concluded that silylation with BSTFA followed by GC-MS analysis allows the simple, convenient and exact determination of panthenol, cholecalciferol and tocopherol.
