We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...
In the highly alkaline environment of concrete, carbon steel rebar is protected against corrosion by a passive oxide/oxyhydroxide film. Understanding the characteristics of this passive film, and how it depassivates, is the key for mitigating problems associated with steel corrosion in concrete. Although a large number of electrochemical and analytical...
Best available copy. In 1984, longstanding concerns about pollution in Yaquina Bay impelled the U.S. Food and Drug Administration to make a comprehensive sanitary survey of the Yaquina River, with particular emphasis on areas where oysters were grown. The report states that the oyster plots endured "sporadic poor water quality,"...
Humans and rodents experience declines in reference (long-term) and working (short-term)
memory and cognitive flexibility during the aging process. Aging changes in GluN1 and
GluN2B subunits of N-methyl-D-aspartate (NMDA) receptors show a relationship to both
reference and working memory deficits. Sulindac, an anti-inflammatory drug, enhances working memory and NMDA receptor...

Sea surface temperature (SST) fronts are determined for the 2001–2004 time period
from Geostationary Operational Environmental Satellites (GOES) data in the California
Current System (CCS). The probability of detecting a SST front at an individual pixel
location in the CCS is presented as a bi-monthly climatology. Fronts clearly indicate the...
The development of a least squares model for the
determination of compliance constants from various combinations
of vibration frequency, mean square amplitudes
of vibration and centrifugal distortion data is discussed.
The resultant model is applied to frequency and mean square
amplitude data for NO₂ and N₂O₄ and to frequency and...
The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...
DRAFT REPORT. In 2013 – 2015, reconnaissance observations were made across non-forest habitats on FS and BLM land in the Coast Range and Cascade foothills within the Salem and Eugene BLM district areas for plant communities that did not fit the USFS Northwest Oregon Non-forest Plant Community guide. Surveys were...
OBJECTIVES: Secondary caries is the most common reason for composite restoration replacement and usually forms between dentin and the filling. The objective of this study was to investigate the combined effect of cyclic loading and bacterial exposure on bacterial penetration into gaps at the interface between dentin and resin composite...
