  • Identification and systematics of larvae of Artedius, Clinocottus, and Oligocottus (Scorpaeniformes:Cottidae)

    Creator:
    Washington, Betsy B.
    Abstract:
    Complete, identified, developmental series of larval cottids Artedius fenestralis, A. creaseri, A. meanyi, Oligocottus snyderi, Clinocottus embryum, and C. globiceps are described for the first time. In addition, redescriptions of four species, Artedius harringtoni, A. lateralis, Oligocottus maculosus, and Clinocottus acuticeps are included that provide new and comparative information on...

  • Consumer use and understanding of unit pricing in two cities : Portland, Oregon and Seattle, Washington

    Creator:
    Close, Betsy L.
    Abstract:
    The purpose of this study was to identify the factors that influence the use and understanding of unit pricing. Furthermore, a comparison between a city with a mandated unit pricing program (Seattle, Washington) and a city with a voluntary unit pricing program (Portland, Oregon) was made. The intent was to...

  • Influence of dietary factors on tansy ragwort toxicosis in rats and horses

    Creator:
    Garrett, Betsy Jayne
    Abstract:
    Several experiments were conducted to investigate the effect of dietary factors such as amino acids, B vitamins, butylated hydroxyanisole (BHA) and phenobarbital on pyrrolizidine alkaloid toxicosis in rats and horses. The influence of St. John's wort, bracken, comfrey, and alfalfa on tansy ragwort toxicity was also examined. Effects of dietary...

  • Ultraviolet radiation as an environmental stressor of amphibians

    Creator:
    Bancroft, Betsy A.
    Abstract:
    My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...

  • Songbird populations of precommercially thinned and unthinned stands of ponderosa pine in east-central Washington

    Creator:
    Putnam, Betsy June
    Abstract:
    Populations of breeding birds and forest composition and structure were examined in preconimercially thinned and unthinned ponderosa pine (Pinus ponderosa Laws.) stands in east-central Washington. Stands were composed of predominantly ponderosa pine with a multi-aged structure made up of small even-aged clumps. Thinning reduced the density and foliage volume of...

  • Flow visualization for wake formation under solitary wave flow

    Creator:
    Seiffert, Betsy Rose
    Abstract:
    The use of data extracted from particle image velocimetry (PIV) along with vector and tensor visualization techniques provides a valuable tool for understanding a complex flow field. By studying a simple geometric structure such as a cylinder under a simple transient waveform, fundamental mechanisms of wake development under solitary wave...

  • Oxygen absorption in water using a multiple stage crosscurrent packed tower with and without recycle

    Creator:
    Towle, Betsy
    Abstract:
    The performance of a multiple stage crosscurrent tower packed with Pall rings was characterized with and without a recycle loop on the gas stream. The column used 12 baffles. The absorption system studied was the transfer of oxygen from an oxygen-enriched air stream into a water stream which is a...

  • B-cell heterogeneity in salmonids

    Creator:
    Irwin, Michael J.
    Abstract:
    Salmonid B lymphocytes were stimulated both in vivo and in vitro and shown to produce antibody specific for the immunogen. A passive hemolytic plaque assay was employed to demonstrate B cells producing specific antibody. Characterization of plaque forming cells (PFCs) involved sequential inhibition with a series of graded concentrations of...
