    Notes: A double-Wollaston prism laser differential interferometer (LDI) has been developed to observe, for the first time, the evolution of the imploding current sheath (CS) and the high temperature and high density plasma pinch in the plasma focus. The light source is a Q-switched and frequency-doubled YAG laser operated in a single-pulse mode: λ=532 nm, the pulse width (FWHM) about 10 nm (also the resolution time of the LDI). The LDI measures density gradients and has a line sensitivity of about ne′=(2.58±0.46)×1025 m−4 for a typical sheath thickness of 1.6 mm and a minimum distinguishable fringe shift of 5%, and a spatial resolution of 1.26 mm. The density gradient and equivalent density of the CS are measured to be ne′(approximate)(2.58±0.46)×1026 m−4 and ne(approximate)(3.25±0.59)×1023 m−3, respectively. More importantly in this article, the double-Wollaston prism LDI, with a simple optical arrangement, gives direct physical pictures of the high density gradient plasma configuration and structure which are of interest in studying the status of plasma motion. © 1997 American Institute of Physics.

    Notes: By applying an after acceleration electric field, the detection and registration of the ion species and spectral distribution of low energy ion beams (〈1 keV) have been achieved by the Thomson spectrometer with CR-39 nuclear track detector as detection plate. With the use of this modified spectrometer, the low energy and high energy density plasma ion beams generated by a coaxial plasma gun have been detected and investigated. The ion beams were mainly N+ ions and were distributed in the energy range from E∼0.12 to 0.4 keV. © 1997 American Institute of Physics.

    Growth of cubic boron nitride on Si(100) by neutralized nitrogen ion bombardment (1994)

    Notes: Highly cubic phase and stoichiometric boron nitride films were deposited on Si(100) substrates using a neutralized nitrogen beam and electron beam evaporation of boron. High intensity, focused, and low-energy neutralized nitrogen beam was supplied using a newly developed neutralizer atomic beam ion source (NABS) adapted to a Kaufman-type ion source. The films were grown at substrate temperatures in the range 400–500 °C and a boron evaporation rate of 0.2 A/s. Infrared transmittance spectra of the films showed that a highly cubic phase (80%) was obtained in the area of the focused beam. These films were compared to those obtained using similar conditions but with the NABS disconnected from the ion source, and it was found that the cubic phase content decreases drastically (10%). The results show that the NABS was the determining factor in enhancing the formation of the cubic boron nitride films. Furthermore, the addition of Ar to N, which is reported to increase the momentum transfer and promote the formation of the cubic phase, did not play a significant role when the NABS was used.

    Notes: Boron nitride (BN) thin films (containing mixed cBN/hBN phase) have been deposited on Si(100) substrates using neutralized nitrogen beam and electron beam evaporation of boron. All as-deposited BN films were p type with a room-temperature carrier concentration in the range of 5×1016 to 1×1017 cm−3. The Mg-doped BN films showed carrier concentrations in the range of 1.2×1018 cm−3 to 5.2×1018 cm−3 when the Mg cell temperature was varied from 250 to 500 °C. The films were analyzed for both majority elements (B and N) and dopant/impurity (Si, Mg, Fe, etc.) incorporation using secondary ion mass spectroscopy and mass spectroscopy of recoiled ions (MRSI). MRSI is shown to be superior for dopant characterization of boron nitride thin films. © 1996 American Institute of Physics.

    The Determinants of DSS Success: An Integrated Model (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Decision sciences 23 (1992), S. 0

    Topics: Economics
    Notes: The results of a field study investigating the determinants of decision support systems (DSS) success are presented. A multivariate model was developed and tested using multiple regression hierarchical analysis on responses from 118 DSS users. Several specific hypotheses are also proposed and tested. Data analyses indicate that DSS success, as measured by DSS satisfaction and perceived benefits, depends on several factors: previous user experience with DSS, user involvement, user training, top management support, information sources, the level of managerial activity, and task structure, difficulty and interdependence. Based on the research results, several suggestions are made to improve the likelihood of successful DSS implementation.

    Treatment of Aqueous Nitrate by Zero Valent Iron Powder in the Presence of CO2 Bubbling (2004)

    Notes: This paper investigates a process for the removal of nitrate from ground water by combination of Fe° and CO2 bubblin*** The bubbling of CO2 effectively creates an acidic environment favorable to Fe° corrosion, which results in nitrate reduction. I 10 min, the solution pH dropped to 3.2 with CO2 inflow rate of 500 mL/min. In the presence of Fe° (2 g/L), the CO2 bubblin (500 mL/min) induced conversion of nitrate-N (∼7 mg/L) by 85% in 40 min. In addition, the end product in the reaction mi***xture was ammonium, which accounts for 90% to 104% of nitrate conversion with the presence of various iron dosages (0.5 t 2.0 g/L). Though the formation of ammonium is a drawback, the ammonium was eliminated from aqueous phase by a follow up treatment of settling (30 min) and air aeration (50 min).

    Notes: : To improve the characteristics of fish muscle, Monascus purpureus or Monascus species was inoculated in 2.1% rice powder broth containing 30% minced mackerel tissue to produce a fermented fish product. Enterbacteriaceae, Staphylococcus, and Pseudomonas were not present during the 7 d of fermentation at 25 °C. The activities of both amylase and acidic proteases were detected after 1 and 2 d of fermentation, respectively, and further increased during fermentation. The volatile base nitrogen of all Monascus fermented samples were lower than the limit of food regulation in Taiwan (〈 25 mg/100 g) even after 7 d of fermentation. Hydrolysis of the muscle protein and accumulation of free amino acid were observed. The fermented fish products had good flavor and color that were highly likeable to the sensory panel.

    Notes: The World Wide Web (WWW) or the Web has been recognized as a powerful new information exchange channel in recent years. Today, an ever-increasing number of businesses have set up Web sites to publicize their products and services. However, careful planning and preparation is needed to achieve the intended purpose of this new information exchange channel. This paper proposes a comprehensive framework for effective commercial Web application development based on prior research in hypermedia and human-computer interfaces. The framework regards Web application development as a special type of software development project. At the onset of the project, its social acceptability is investigated. Next, economic, technical, operational, and organizational viability are examined. For Web page design, both the functionality and usability of Web pages are thoroughly considered. The use of the framework should result in more effective commercial Web application development.
