  • Behavior of large waterdrops in shear flow

    Creator:
    Caldwell, Douglas R. and Elliott, W.P.
    Abstract:
    Nondimensionalized equations of motion for waterdrops, not necessarily obeying Stokes's law, are derived and used to calculate the response of various size drops to changes in horizontal wind speed. We find that (1) cloud drops respond almost instantaneously to changes in wind speed, whereas raindrops require considerable time to adjust,...

  • Temporal variability of suspended matter in Astoria Canyon

    Creator:
    Plank, William S., Zaneveld, J. Ronald, and Pak, Hasong
    Abstract:
    Suspended matter in Astoria canyon was monitored by means of an in situ nephelometer and by means of light-scattering and particle concentration measurements performed aboard ship on water samples. Nephelometer profiles obtained along the axis of the canyon in February and April 1973 indicate that the canyon is divided into...

  • Workshop on problems of assessing populations of nekton

    Creator:
    Pearcy, William G.
    Abstract:
    A workshop was held in Santa Barbara, California, associated with assessing the populations of nekton animals such as squids, shrimps and fishes. Sessions four major methods of assessing nekton populations: (1) Net collections (2) Acoustics (3) Egg/larval surveys (4) Visual methods, remote sensing and feeding habit studies An attempt was...

  • Pyrrolizidine Alkaloids: Their Occurrence in Honey from Tansy Ragwort (Senecio jacobaea L.)

    Creator:
    Burgett, D. Michael
    Abstract:
    The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which include senecionine, seneciphvlline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic and teratogenic and may pose health hazards to the human consumer.

  • Growth rules in the marine copepod genus Acartia

    Creator:
    Miller, Charles B., Johnson, John Kenneth, and Heinle, Donald R.
    Abstract:
    Several species of the copepod genus Acartia are shown from existing data to complete each molt-to-molt phase of the life cycle in a constant time period. This molting pattern is termed isochronal development. Increase in mass at each stage is a nearly constant fraction of the weight at the beginning...

  • Spectral distribution of solar radiation. I: direct radiation

    Creator:
    McCartney, H. A. and Unsworth, Michael H.
    Abstract:
    Measurements of the spectral distribution of direct solar radiation, made in both wide and narrow wavebands, are reported. The measurements suggest that the wavelength dependence of aerosol attenuation in central England, in summer, can generally be described by a power law with wavelength exponent of about 1.7. Attenuation of visible...

  • Single photon timing system for picosecond fluorescence lifetime measurements

    Creator:
    Turko, Bojan T., Nairn, John A., and Sauer, Kenneth
    Abstract:
    A single‐photon timing system is described which is capable of extracting fluorescence lifetimes as short as 25 ps. The system is an improved version of an earlier apparatus. The new system uses a synchronously pumped, mode‐locked dye laser with 10‐ps pulses operating at 82‐MHz repetition rate. A fast photodetector and...

    Abstract:
    Poetry in the People's Republic of China during the past 30 years has been dominated by works intensely political in nature – a kind of poetry known by the name zhengzhi shuqing shi (political lyric). The function of this poetry was to eulogize current political movements and to generate public...

  • A Nonlinear Pseudoparabolic Diffusion Equation

    Creator:
    Böhm, Michael and Showalter, R. E.
    Abstract:
    Diffusion in a fissured medium with absorption or partial saturation effects leads to a pseudoparabolic equation nonlinear in both the enthalpy and the permeability. The corresponding initial-boundary value problem is shown to have a solution in various Sobolev-Besov spaces, and sufficient conditions are given for the problem to be well-posed.
