    The stimulated Raman threshold. I. Experiment (1986)

    Notes: The threshold intensity for excitation of the stimulated Raman backscatter instability has been measured at 9.58 μm in a well-diagnosed plasma free of Brillouin scattering. The initial level of density fluctuations was independently measured by ruby laser scattering. The observed threshold of 1×1011 W/cm2 is somewhat below the calculated "absolute'' threshold for underdense plasmas, and the apparent noise level is higher than that measured directly.

    Physical mechanisms for hot-electron stabilization of low-frequency interchange modes (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 3567-3571 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The stabilization of low-frequency background and hot-electron interchange modes is studied by using a relatively simple multi-fluid model. Physical pictures for the stabilization mechanisms such as the "charge-uncovering'' effect are given and compared with the stabilization of interchange modes by the finite Larmor radius (FLR) effect.

    Raman scattering in a nearly resonant density ripple (1987)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 30 (1987), S. 1180-1188 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: Stimulated Raman scattering of light waves by an underdense plasma is affected by the presence of a density ripple caused by a simultaneously occurring stimulated Brillouin instability. The problem is treated kinetically for the particularly interesting case where the ripple has nearly the same wavelength as the plasma wave. The ripple is found to reduce the growth rate of the usual Raman instability but allows other decay modes to occur. Numerical results for the frequencies, growth rates, and k spectra of these modes are obtained. A physical explanation is given for a baffling result of the calculation. The physical picture is also of interest to particle acceleration by plasma waves.

    Use of the two-ion hybrid as an impurity diagnostic (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 1651-1658

    Notes: In a plasma containing more than one ion species, the frequencies of the ion–ion hybrid resonances can be a sensitive measure of the densities of the minor species, but only if the frequency shifts caused by electron motions are small, as experimental observations suggest. By calculating the eigenfrequencies for ion–ion hybrid waves taking into account collisions, Landau damping, electron inertia, electromagnetic effects, and density gradients, it is found that the frequency shifts are not negligible unless k(parallel) is extremely small. Treatment of the sheath boundary conditions at the ends of a plasma column shows that the effective value of k(parallel) can indeed be sufficiently small, and that the uncorrected resonance frequency is surprisingly accurate over a wide parameter range. Data from an Ar–Xe discharge demonstrate the usefulness of this technique for measuring impurity concentrations.

    Detection of Enocyanin in Cranberry Juice Cocktail by Color and Pigment Profile (1985)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Addition of enocyanin to cranberry juice cocktail can be determined by a four-step color and pigment profile. Enocyanin colorant is slightly more blue, therefore, a simple measurement of color will detect samples with 12% or less cranberry juice. Cranberry juice cocktail normally contains 25% cranberry juice. Anthocyanins and flavonoids, recoverable by a CG-50 ion exchange column, are lower in samples with 12% or less cranberry juice. Anthocyanin aglycones, found in grapes and not in cranberries, can be detected by paper chromatography in Formic reagent. Replacement of 50% of cranberry juice by a solution of enocyanin and citric acid, can be detected by paper chromatography of anthocyanins in 1% HCl in water.

    Blueberries as a Colorant Ingredient in Food Products (1985)

    Notes: Frozen wild and cultivated blueberries were used as colorants at two levels in three model systems. Liquid beverage and condiment samples were measured by light transmission and read as Judd-Hunter L, a, b units. Opaque topping samples were measured by light reflection, recorded in L, a, b units with visual reference to Munsell Color System. Hue angle theta was calculated for all samples. Pigment analyses were done by acid-ethanol extraction and calculated as cyanidin-3-glucoside. Lower pH model systems had redder color; higher pH products had bluer color. Wild blueberries had high pigment content. The color was related to the pigment content.

    A Research Note Stability of Anthocyanins from Zebrina pendula and Ipomoea tricolor in a Model Beverage (1988)

    Notes: Anthocyanins from two sources with reported high stability, Ipomoea tricolor and Zebrina pendula, were compared with extracts from blackberries containing mainly cyanidin-3-glucoside (Cn-3-G) and a commercial enocyanin. The pigment samples were formulated in a sugar, citrate-phosphate buffer solution for storage at room temperature. Tristimulus color data and pigment retention were measured at periods up to 82 weeks. The Ipomoea pigments were the most stable. Zebrina and Cn-3-G samples were similar followed by enocyanin. Deacylated pigments from both Ipomoea and Zebrina were the least stable indicating that the acyl groups conferred stability.
