Calibration and verification of HSPF model for Tualatin River Basin Water Quality

Creator:: Tang, Fei
Abstract:: The Tualatin River Basin is located in the Washington County, Oregon. The river was detected having high chlorophyll a concentration and low dissolved oxygen concentration during summer time, which violated DEQ water quality standards. A mathematical model (HSPF) was used to simulate physical, chemical and biological processes in the basin...

The willingness of Central Oregon irrigators to donate water rights to augment Deschutes River flow

Creator:: Barkley, David, 1972-
Abstract:: This study used contingent valuation techniques to estimate the willingness of central Oregon Irrigators to donate a portion of their water rights to increase Deschutes River flow. This study was different from previous contingent valuation studies in that it used water rights as the payment vehicles instead of dollars -...

Giving color to Oregon's gray water market : an analysis of price determinants for water right

Creator:: Landry, Clay J.
Abstract:: Many parts of the West are experiencing substantial growth pressures that have increased the demand for water. These new demands come at a time when most of the water in the West has been fully appropriated by traditional uses such as agriculture, mining, and industry. Some attempts are being made...

Analysis and design of bandpass delta-sigma A/D converters

Creator:: Zhai, Dalun
Abstract:: A new approach to oversampled delta-sigma A/D converters ( AZ modulators ) is introduced, where a differential pseudo-Npath filter stage is used as a basic cell. In this band-pass application, the z to -zN transformation is employed to realize a RAM-type pseudo-2-path lossless integrator. The bandpass second-order and 4th-order delta-sigma...

Fire effects on vegetation diversity, structure, and successional dynamics in shrub-steppe and mixed conifer environments of the Hells Canyon, Idaho

Creator:: Havlina, Douglas William
Abstract:: The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...

Compulsive-addictive buying behavior : exploring effects of chilhood experiences and family types

Creator:: Friese, Susanne, 1967-
Abstract:: This exploratory study investigates the probable causes of compulsive-addictive buying behavior, employs the family system's theory developed by Constantine (1986) as a theoretical framework, and develops an appropriate measuring scale in order to classify individuals according to family types. The purpose of the study is to examine the influence of...

Habitat associations of woodpeckers at multiple scales in managed forests of the Southern Oregon Cascades

Creator:: Brett, Tiffany A.
Abstract:: I studied nest-site characteristics and habitat relationships for three species ofprimary cavity-nesting birds--hairy woodpecker (Picoides villosus), northern flicker (Colaptes auratus), and red-breasted sapsucker (Sphyrapicus ruber)-- over spatially heterogeneous landscapes in managed forests of the Southern Oregon Cascades during 1995 and 1996. The study was conducted on the Diamond Lake Ranger...

Characterization of fire effects on forest ecosystems in the Tillamook Forest, Oregon

Creator:: Chen, Shu-Huei
Abstract:: From the 1920's through 1951 several severe fires occurred in the predominantly conifer forest ecosystems of the northern Oregon Coast Range. Of the 211,151 ha. of mapped area, 57 percent was burned. The effects of frequent fires with high severity on forest ecosystems over time at the landscape level is...

Composing ourselves : women's use of personal journals for freedom, creativity and autobiography

Creator:: Perkins, Audrey L.
Abstract:: Scholars are ushering autobiographical writing of all kinds into the world of literary and scholarly writing: in course titles and syllabi, in academic journals and on bookshelves, autobiographical writing is flourishing. People's real stories offer insights into how people really live and view this life. They offer perspectives which necessarily...
