In the first part of this work, thin films of Al₂O₃ deposited via atomic layer deposition (ALD) are demonstrated to improve the thermal stability of cellulose nanocrystal (CNC) aerogels. ALD is a chemical vapor deposition (CVD) like method in which sequential precursor exposures and self-limited surface reactions produce a conformal...
A study was conducted to investigate if morphometric facial measurements could be utilized to differentiate five categorical performance types of Quarter Horses. The five categories being Western, Halter, English, Reining, and Cutting. The measurements were collected from 323 registered Quarter Horses representing animals who ranged in age from one year...
Each NWR within the U.S. Fish and Wildlife Service (FWS) National Wildlife Refuge System (NWRS) provides landscapes that contribute to conservation of wildlife and the habitats they depend on at local, regional, and national levels. The Integrated Pest Management Plan (IPMP) for a given refuge is a guide to how...
Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...
Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...
The syllid polychaete Autolytus varius reproduces in the spring
and early summer in Yaquina Bay, Oregon, The fertilized female
epitokes, or Sacconereis, carry the developing eggs and larvae in a
ventral sac until the larvae are ready to be released; incubation
lasts 14 to 18 days in the laboratory, The...
The importance of language and bilinguality in the
development, perpetuation, and "degeneration" or change of
culture is a central theme throughout this treatise.
Original pictorial representations of Mayan hieroglyphic
sculpture are included as examples, and represent artistic
styles and language variations of written Cholan and
Yucatec. Modern Cholan and Yucatecan...
Waldo Lake, located in the Oregon Cascades, is
considered to be one of the most dilute lakes in the
world. Even with very low nutrient concentrations and
sparse populations of zooplankton, introduced fish in the
lake are large in size and in good condition when compared
to fish from other...
This report deals with a group of mineralized areas containing Tertiary veins of base metal and gold,· which occur at intervals throughout the Cascade Range in Oregon. Gold was discovered in this region in 1858, only a few years after its discovery in southwestern Oregon, and an output of nearly...
The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
