    Notes: Enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting classified 97 phenol-degrading isolates with identical amplified ribosomal DNA restriction analysis (ARDRA) patterns into six genotypic groups. The 16S rRNA gene of the representative isolate of each group had higher than 99.47% common identity with each other and higher than 98% identity with the type strain of Alcaligenes faecalis. PCR-TGGE (temperature gradient gel electrophoresis) analysis of the genes of the largest subunit of the multi-component phenol hydroxylase (LmPH) in each isolate followed with sequencing showed that isolates within each ERIC-PCR group had identical LmPH gene sequences. Among the six different ERIC-PCR groups, two were found to harbor two different LmPH genes encoding low- and high-Ks (affinity constants) phenol hydroxylases, and the low-Ks type LmPH was identical in sequence with one predominant LmPH of the parental activated sludge. Three ERIC-PCR groups had only the high-Ks type and one had no sequence similar to the known LmPHs. Our work suggests that there is no correlation between the phylogenetic groupings of phenol-degrading bacteria and their LmPH genotypes possibly due to extensive horizontal gene transfer of this functional gene.

    Notes: : Five types of land use/land covers in the West Tiaoxi watershed of China were studied for nutrient losses in artificial rainstorm runoff. A self-designed rainfall simulator was used. In situ rainfall simulations were used to: (1) compare the concentrations of nitrogen and phosphorous in different land use/land covers and (2) evaluate the flux of nitrogen and phosphorous export from runoff and sediment in various types of land use/land covers. Three duplicated experiments were carried out under rain intensity of 2 mm/min, each lasting 32 minutes on a 3 m2 plot. Characteristics of various species of nitrogen and phosphorous in runoff and sediment were investigated. The results showed that the concentrations of total nitrogen (TN) and total phosphorous (TP) were greatest in runoff from mulberry trees and smallest from pine forest. The TN and TP export was mainly from suspended particulate in runoff. TN and TP exports from the top 10 cm layer of five types of land use/land covers were estimated as high as 4.66 to 9.40 g/m2 and 2.57 to 4.89 g/m2, respectively, of which exports through sediment of runoff accounted for more than 90 percent and 97 percent. The rate of TN and TP exports ranged from 2.68 to approximately 14.48 and 0.45 to approximately 4.11 mg/m2/min in runoff; these rates were much lower than those of 100.01 to approximately 172.67 and 72.82 to approximately 135.96 mg/m2/min in the runoff sediment.

    Notes: : Major parameters and optimum storage volumes of rooftop rain water harvesting systems (RRWHSs) have not been investigated in detail in Taiwan. Accordingly, the four major parameters of RRWHSs were herein identified and elucidated using a simulation method. Because the performance of the RRWHSs is sensitive to the runoff coefficient, a field experiment was conducted to determine the runoff coefficient more precisely for various types of roofs. A simulation model including production theory was developed and employed to estimate the most cost effective combination of the roof area and the storage capacity that best supplies a specific volume of water. Consequently, the expansion path of optimum solutions for different volumetric reliability of water supply can be determined. Additionally, the method based on the marginal rate of substitution can be used for determining the rational volumetric reliability. The procedures developed herein constitute an effective tool for preliminarily estimating the most satisfactory storage capacity of any specific roof area and for determining the rational reliability of a corresponding water supply.

    RATIONAL INDUSTRIAL WATER REUSE RATIOS (2004)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 40 (2004), S. 0

    Notes: : This work begins by defining rational water use, and then discusses important factors that most strongly influence it. A general model is then developed to enable factories to quantify the ratio of rational industrial water reuse based on the least cost method. The model is established to minimize the cost of water with reference to gross water use and three subsystems - the intake, reuse, and discharge of industrial water. Discharge cost is determined using data from a 1997 survey of 38 factories, and reuse costs are ranked and expressed by a step function. The model is verified using data from a typical semiconductor factory in northern Taiwan's Hsinchu Science Based Industrial Park, whose effective rational water reuse ratio is about 38 percent. A sensitivity analysis shows that improving water reuse technology is the most important factor in determining the rational water reuse ratio, and the price of water is the second most important. When water costs over NT$30 (New Taiwan Dollar, US$1 = NT$34) per cubic meter, increasing reuse becomes significant. The model provides a step towards the scientific management of industrial water.

    Notes: Intrusion detection systems help network administrators prepare for and deal with network security attacks. These systems collect information from a variety of systems and network sources, and analyze them for signs of intrusion and misuse. A variety of techniques have been employed for analysis ranging from traditional statistical methods to new data mining approaches. In this study the performance of three data mining methods in detecting network intrusion is examined. An experimental design (3times2x2) is created to evaluate the impact of three data mining methods, two data representation formats, and two data proportion schemes on the classification accuracy of intrusion detection systems. The results indicate that data mining methods and data proportion have a significant impact on classification accuracy. Within data mining methods, rough sets provide better accuracy, followed by neural networks and inductive learning. Balanced data proportion performs better than unbalanced data proportion. There are no major differences in performance between binary and integer data representation.

    Notes: The mechanisms of knowledge management include knowledge sharing, knowledge transformation and knowledge accumulation. In the corporate context, knowledge creation is of utmost importance for the promotion of competition within an organization. Knowledge creation in business corporations is most frequently done through sharing knowledge between members of a team. Therefore, how to promote the flow of ‘Chi’ in an organization to ensure the effectiveness of knowledge sharing becomes the key to successful knowledge creation. Moreover, to create and maintain ‘Chi’, a holonic working environment has to be created so that the result of knowledge sharing can be enhanced. This paper illustrates the effectiveness of the knowledge-sharing practices of three computer-manufacturing companies from the perspective of working environment design and knowledge-sharing mechanism. Through comparison, this paper will identify some good practices for the enhancement of organizational creativity.

    The impact of revenue-neutral tax policy on plant location under price uncertainty (2000)

    Notes: Abstract. This research note incorporates price uncertainty into a production-location model and examines the impacts of a revenue-neutral tax policy on production and location decisions. In particular, it is shown that under an assumption of decreasing absolute risk aversion, a revenue-neutral rise in the marginal tax rate increases the firm's output and causes the firm to move its plant closer to (away from) the market center provided that the production function exhibits increasing (decreasing) returns to scale. Nevertheless, the plant location remains unchanged as a result of a revenue-neutral tax policy if the production function is constant returns to scale. A comparison between revenue-neutral and income or lump-sum taxes and hence some important policy implications are also provided in the analysis.

    Notes: : This study evaluated the antioxidative activities of 50% ethanolic extract from red bean (Phaseolus radiatus L. var. Aurea). The antioxidative activities, including α,α-diphenyl-β-picryl-hydrazyl (DPPH) radicals scavenging effects, Fe2+-chelating ability, and reducing power, were studied in vitro. The antioxidative activity was found to increase with the concentration of the extract to a certain extent and then level off as the concentration further increased. Compared with commercial antioxidants, the red bean extract showed less scavenging effect on the DPPH radical and less reducing power than α-Tocopherol and BHT, but better Fe2+-chelating ability. No mutagenic effect toward any tester strains was found in the 50% ethanolic extract of red bean.

    Notes: : Two-cycle rapid-visco analysis was performed on the admixture of 1% hsian-tsao leaf gum and 2% wheat starch as a function of salt types and concentrations. The salt concentrations (Cs) studied were 5 to 75 mM for sodium and potassium chloride, and 3.4 to 8.5 mM for calcium and magnesium chloride. The gelling temperature, gelling rate and gel viscosity of the mixed system increased with increasing Cs. In addition, the melting temperature increased, but melting rate and percentage of viscosity loss decreased with increasing Cs. These results indicated the presence of appropriate amount of salts could facilitate and reinforce the formation of junction zones, and provided a more pronounced thermal resistance.
