The merits of the photoelastic coating technique as applied to
wood were evaluated. Comparative tests were made on 12 nominal
two-by-four Douglas Fir boards. The object of these tests was to
determine the limitations of this technique, such as accuracy and
complexity of experimental procedure. Correlation of the experimental
results...
Objective: To examine the pricing trajectories in the United States of disease-modifying therapies (DMT) for multiple sclerosis (MS) over the last 20 years and assess the influences on rising prices.
Methods: We estimated the trend in annual drug costs for 9 DMTs using published drug pricing data from 1993 to...
The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
Intensive observations were made of play behavior in the
young hamster (Mesocricetus auratus) from 14 to 54 days of age.
Behavior was recorded using movie film and a multi-channel event
recorder.
Play was first seen at 14 days of age. The amount of play
increased rapidly thereafter, remaining relatively high...
In order to appraise timber, it is necessary to estimate logging costs with reasonable accuracy. The purpose of this study is to provide a rethod for estimating log loading costs in the Intermountain Region. Nine different log loaders were studied loading from cold decks on six USDA. Forest Service timber...
In this memoir, by alumnus and Zoology Department instructor William J. Gilstrap, the author details various aspects of his life, including: childhood in Missouri, student experience at Oregon Agricultural College (OAC) in the 1890s, and his medical practice in various Oregon locales. Gilstrap also describes in this narrative the origins...
Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...
Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...
