Botanical composition and diet quality of beef cattle grazing at three stocking rates following fuels reduction in mixed conifer forests

Creator:: Clark, Abe A.
Abstract:: An experiment was conducted to evaluate the influence of forest fuels reduction on the diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with the whole plots (3 ha) being fuel reduced or no treatment...

Response to Hypoxia in the staghorn sculpin, (Leptocottus armatus)

Creator:: Wagner, Sara Anne
Abstract:: Long-term subae lal survival has been anecdotally noted in the staghorn sculpin, Leptocottus armatus. In this study, I quantified this phenomenon physiologically by examining the following parameters: standard metabolic rate and indications of reduced standard metabolic rate during subaerial exposure; capacity for and mechanism(s) of oxygen consumption in air; capacity...

Factors affecting coho salmon production in Oregon

Creator:: Scarnecchia, Dennis Leslie
Abstract:: Eight scale characters of known hatchery and wild coho salmon (Oncorhynchus kisutch) were compared, and a linear discriminant function was used to determine if hatchery and wild adult coho salmon could be correctly identified by their scales. Eighty-two percent of the hatchery and 89% of the wild fish were correctly...

Sexuality education in Montana public high schools with a focus on implementation

Creator:: Wagner, Bonnie S.
Abstract:: The primary purpose of this study was to determine whether the 1981 recommendation by the Montana State Board of Public Education had in fluenced actual implementation of sexuality education in that state. The study also sought to describe sexuality education in Montana and to assess perceptions of Montana public high...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...

A comparison of experimental mode I analysis methods for the interlaminar fracture toughness characterization of graphite/epoxy composite materials

Creator:: Keary, Paul Edward
Abstract:: Three approaches for evaluating mode I interlaminar strain energy release rates in graphite/epoxy composites were compared using experimental data from double cantilever beam specimens. Expressions for evaluating strain energy release rates were arrived at based on assumptions regarding specimen geometry and material behavior. The calculations included the direct method of...

Low Maintenance Strategies and Challenges within Oregon School Landscapes

Creator:: Gould, Micah A.
Abstract:: Ornamental landscapes require considerable amounts of inputs, including but not limited to irrigation, mowing or pruning, fertilization, and pest management. However, school systems have limited budgets, which reduce their access to resources and labor hours. Therefore, the objective of this project is to identify ground covers that can compete with...

Using advanced spreadsheet features for agricultural GIS applications

Creator:: Halbleib, Michael D.
Abstract:: A GIS analysis procedure was developed to explore relationships between imagery, yield data, soil information, and other assessments of a field or orchard. A set of conversion utilities, a spreadsheet, and an inexpensive shape file viewer were used to manipulate, plot, and display data. Specific features described include procedures used...

A controlled negative-resistance for realization of certain network functions

Creator:: Wagner, James Daniel
Abstract:: A circuit which functions as a controlled negative-resistance is described and analyzed; the circuit contains two transistors, a breakdown diode, and five resistors connected in a stable feedback configuration. From the analysis a set of design equations is derived. An experimental circuit is described and a comparison between measured performance...

A geology training manual for Grand Canyon National Park

Creator:: Wagner, Stacy S.
Abstract:: Grand Canyon National Park is a geologic experience like no other. Each year, many of the park's 5 million visitors attend ranger-led interpretive programs to learn how the spectacular scenery formed. It is crucial for interpretive park rangers at'Grand Canyon to understand the geologic history of the region and be...
