Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.

The Harderian gland (HG) of the red-sided garter snake, Thamnophis sirtalis parietalis, is a secretory structure that plays a role in the vomeronasal system by solubilizing semiochemicals such as prey chemoattractants and the female sexual attractiveness pheromone. The HG produces secretions containing pheromone-binding proteins that form a complex with pheromone...
A trial was conducted to determine the effects of increasing
levels of water restriction on body weight, feed consumption, feed
conversion and mortality of broiler chicks to eight weeks of age.
In addition, the effects of water restriction on water:feed ratios,
water consumption per pound of body weight and on...
The ingestion, uptake, and metabolism of liposomes by juvenile
Pacific oysters (Crassostrea gigas) were studied by several methods in
an effort to assess their potential as encapsulating agents. Liposomes
composed of egg phosphatidylcholine-cholesterol-stearylamine (7:1:2)
formed readily and appeared stable in 20°/oo seawater. Radiotracer
studies with liposomes made with ¹⁴C-labeled cholesterol...
Industries such as science, technology, engineering and mathematics (STEM), continue to employ fewer women compared to men. These professions that are traditionally considered more masculine sustain gender-imbalanced work forces and are also unattractive to women at an academic level. This thesis explores the hypothesis that performance can be a powerful...
The proper way to order knowledge and find truth about the natural world in the eighteenth century lay in one’s ability to correctly learn and employ the quality of reason. While all had the right to seek reason, only a privileged few achieved its proper use, creating an intellectual elite...
Vertebrates communicate with one another and coordinate intraspecific reproduction by using a variety of sexually dimorphic signals, such as plumage, ornaments, sounds, and/or scents. These sexual dimorphisms are maintained by physiological factors, typically sex-specific hormones (though see Chapter 3 for an exception). The purpose of the research in this dissertation...
Although previous research in central Oregon has shown soil compaction can lead to a decline in site productivity, the subject is not understood well enough to predict the growth changes resulting from a given level of soil compaction. A study was initiated to relate the basal area, height and volume...
