    Notes: Diamond like carbon (DLC) films were prepared on Si wafer, using laser induced arc deposition (Laser arc) technique. Results of Raman Spectra analysis showed that the as-deposit films were amorphous, having obvious sp3 structure. Meanwhile, surface topography and micro-tribological properties were investigated by using Atomic Force Microscope and Nano-Scratch Tester. Influences of arc voltage, substrate bias voltage, target materials and substrate pre-treatment methods upon the film structures and film properties were studied

    Notes: In the present study, we evaluated the ability of Weissella cibaria isolated from the oral cavity to coaggregate with Fusobacterium nucleatum, and the adhesiveness of these strains to epithelial cells. W. cibaria efficiently coaggregated with F. nucleatum, and adhered to epithelial cells. We tested the effects of various factors on the coaggregation. The coaggregation and adhesiveness of W. cibaria disappeared upon exposure to pronase or LiCl, suggesting that proteinaceous components on the surface of W. cibaria mediated the coaggregation and adhesiveness. In conclusion, W. cibaria may serve as a potential probiotic with the ability to establish an oral flora protecting against oral pathogens.

    Brand power revisited: measuring brand equity in cyber-space (2005)
    Bingley : Emerald
    The @journal of product & brand management 14 (2005), S. 49-56

    Topics: Economics
    Notes: Purpose - Cyber-brands are regularly valued but, to date, there has been no reported research designed to understand the derivation of cyber brands' equity, so that attempts can be made to increase their brands' equity efficiently. This research aims to address the issue. Design/methodology/approach - To measure the strength of cyber brands, prior off-line research is replicated, taking a customer focus to identify determinate variables. These customer-focused variables are tested against cyber consumers' stated satisfaction and site-visit intention behavior, using regression analysis. Findings - The results satisfactorily justify the suggested model, which has a predictive power ranging from 62 to 72 per cent. Practical implications - The study shows that practitioners intent on raising the power of their cyber brand can be guided by the same model as used off-line. Originality/value - The major theoretical contribution of the study is to show that there is little difference between measuring and increasing brand power on or off-line.

    Effect of dietary vitamin C and ammonia concentration on the cellular defense response of Macrobrachium nipponense (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This study examined the effects of dietary vitamin C and ammonia concentration on the cellular defense response of Macrobrachium nipponese. The response of the cellular defense was determined by monitoring changes in reactive oxygen intermediates in hemocytes, superoxide dismutase activity, catalase activity, glutathione peroxidase activity, glutathione reductase and glutathione transferase activity in muscle. The results showed that prawns fed the basal diet had a significant increase in reactive oxygen intermediates in response to exposure to ammonia-N. When dietary vitamin C was added to the feed, there was a significant decrease in reactive oxygen intermediates in response to exposure to ammonia-N. Total superoxide dismutase and glutathione peroxidase activity of prawns fed the basal diet decreased as ammonia-N increased. This decrease in activity was significantly less pronounced in prawns that were fed the dietary vitamin C supplement. In prawns that were fed the dietary vitamin C supplement there was no significant variation in catalase reductase or gluxathione reductase activity in response to variations in ammonia-N concentration. The glutathione transference activity increased at a low concentration of ammonia-N in prawns that were fed the dietary vitamin C supplement, but there was no significant variation in the prawns fed the basal diet. Overall the results indicate that dietary vitamin C supplements enhance the capacity of M. nipponese to respond to elevations in ammonia-N. This response involved several biochemical reactions known to be involved in cellular defense.

    Abscisic acid activates acid invertases in developing grape berry (2005)
    Oxford, UK; Malden, USA : Munksgaard International Publishers
    Physiologia plantarum 125 (2005), S. 0

    Notes: Acid invertases play a key role in sugar metabolism, and the plant hormone abscisic acid (ABA) enhances sugar accumulation in crop sink organs, but information about the relationship between ABA and acid invertases has been limited. The present experiments were done with both in vivo pre-incubation of the grape (Vitis vinifera × V. labrusca L.) berry tissues in ABA-containing medium and in vivo infiltration of ABA into the intact berries. The results show that ABA activates both the soluble and cell wall-bound acid invertases during fruit development by enhancing their activities and amounts as assessed by immunoblotting or enzyme-linked immunosorbent assay. This activation was pH, time course and ABA dose dependent. The serine/threonine protein kinase inhibitors K252a, staurosporine and H7 and acid phosphatase increased the activation of ABA-induced acid invertase, but the tyrosine protein kinase inhibitor quercetin strongly suppressed the ABA-induced effects, suggesting that a complex reversible protein phosphorylation is involved in the ABA-induced activation of acid invertases. The effects of the protein kinase inhibitors were dependent on the in vivo state of the tissues but independent of the expression of acid invertases. Two ABA analogues, (–)-ABA and trans-ABA, had no effect on acid invertases, showing that the ABA-induced activation of acid invertases is specific to the physiologically active form of ABA. These data suggest that ABA may be involved in fruit development by activating acid invertases.

    Regional and seasonal variations in facial sebum secretions: a proposal for the definition of combination skin type (2005)

    Notes: Background/aims: Facial sebum secretions are known to change under various circumstances. Facial skin types have been categorized as oily, normal, dry, and combination types. However, these have been evaluated subjectively by individuals to date, and no objective accepted standard measurement method exists. The combination skin type is most common, but its definition is vaguer than the definitions of the other skin types.Methods: We measured facial sebum secretions with Sebumeter®. Sebum secretions were measured at five sites of the face seasonally for a year, in the same volunteers. Using the data obtained we developed a set of rules to define the combination skin type.Results: Regional differences in sebum secretion were confirmed. Sebum secretions on forehead, nose, and chin were higher than on both cheeks. Summer was found to be the highest sebum-secreting season, and seasonal variations were found in the T- and U-zones. A mismatch of skin type in the T- and U-zones in more than two seasons appears to be close to subjective ratings of what is described as the ‘combination’ skin type.Conclusion: We showed that the face shows definitive regional and seasonal variations in sebum secretion. To define the combination skin type, seasonal variations in sebum secretion should be considered in addition to regional variations.

    A HYDRODYNAMIC MODELING STUDY TO DETERMINE THE OPTIMUM WATER INTAKE LOCATION IN LAKE PALDANG, KOREA (2005)

    Notes: A three-dimensional hydrodynamic model was applied to Lake Paldang, South Korea. The lake has three inflows, of which Kyoungan Stream has the smallest flow rate and poorest water quality. Since all drinking water intake stations are located near the confluence of Kyoungan Stream within the lake, this contaminated tributary may have a significant impact on the quality of drinking water sources. The optimum drinking water intake location was determined from the applied model. The model was calibrated and verified using the data measured under different hydrological conditions. The model results were in reasonable agreement with the field measurements in both calibration and verification. The circulation and spreading patterns of the incoming flows in the lake, as well as their composition ratios to the drinking water intakes were determined from the model, and three alternative intake locations were proposed. The simulation results suggested that the horizontal and vertical relocations of the intake aqueduct could significantly decrease the composition ratio of the contaminated water. From this study, it was concluded that the three-dimensional hydrodynamic model could successfully simulate the temporal and spatial mixing patterns of incoming flows and become a useful tool in determining the optimum water intake location in Lake Paldang.
