Based on oral interviews with tribal informants, current and former state and federal fisheries personnel, review of records and literature, and presence/absence sampling, it is apparent that Pacific lamprey were once abundant in ceded area streams of the Umatilla Indian Reservation (John Day, Umatilla, Walla Walla, Tucannon, and Grande Ronde...
The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...
This study presents potential Low Impact Development (LID) solutions for the Ash Creek watershed and designs several tools to assist localities in implementing the solutions they may choose. Ash Creek is a tributary of the Willamette River flowing through Dallas, Monmouth, and Independence in Polk County, Oregon. Currently, Ash Creek...
Four years ago, we noted that, although there was a widespread belief that the key to many ocean processes must be the communication of energy by internal waves, there had been little progress in definitely relating small‐scale processes to internal waves (Caldwell, 1983a). For example, although it seemed plausible that...
In a two part thesis, studies were made of two
different types of structure-activity relationships.
The first part consists of the synthesis and biological
evaluation of a number of 4-substituted pyrazoles and
isoxazoles as inhibitors of liver alcohol dehydrogenase.
In an effort to better define the steric and electronic
effects...
Launch uncertainties in uncontrolled direct fire projectiles can lead to significant impact point dispersion, even at relatively short range. A model predictive control scheme for direct fire projectiles is investigated to reduce impact point dispersion. The control law depends on projectile linear theory to create an approximate linear model of...
In a discussion of the turbulence characteristics of patches of 'microstructure' in the ocean, the hypothesis advocated by Gibson (1982), that the patches are produced by very rare but extremely powerful turbulence-generating events which usually have 'fossilized' before their observation, is contrasted with the hypothesis of a turbulence field driven...
The study comparatively analyzed salient components of the
counselor education process of training programs which are accredited
by the American Association of Pastoral Counselors (AAPC) and the
Council for the Accreditation of Counseling and Related Educational
Programs (CACREP). The data of this study were obtained by a Likert
type survey...
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,...
