Grazing cattle usually have access to streams as a
source of drinking water. A model was developed for the
personal computer to predict the bacterial quality of
these streams. The model estimates the number of
organisms that enter the stream by the direct deposit of
feces and by runoff from...
How do we bridge the mismatch between teachers and students based on race and ethnicity currently in our nation's schools? The teaching force remains overwhelmingly White, while the percentage of K-12 students of color continues to rise.

This investigation was designed to investigate the use of an answer-until-correct procedure on multiple-choice quizzes in an independent study mathematics course. This procedure was compared to the standard multiple-choice procedure with respect to student achievement, student anxiety, and test reliability. Using the answer-until-correct procedure students were made immediately aware of...
Previous research suggests a link between litter size in ewes and differential excretion of fecal hormones. An accurate test for fetal number would be useful to sheep producers and a fecal hormone response could be utilized in such a test. Fifteen previously categorized fecal hormones were analyzed within fecal samples...
A study of the life history, population dynamics, and ecological relationships of the Columbian white-tailed deer (Odocoileus virginiarius leucurus) was conducted on the
Washington mainland, Columbian White-tailed Deer National Wildlife Refuge during 1972-1973 to provide information for management of this endangered subspecies. A total of 18,077 observations of deer recorded...
Ninety basalt samples from eight locations in central Oregon
and one location in the Willamette Valley were analyzed for Si and Al.
Fourteen basaltic rock specimens (> 1 kg each) from four buttes in the
Willamette Valley were sampled and analyzed for Si, Al, Fe, Na, K,
Mn, Cr, Co,...
The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...
