Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...
The peripheral-type benzodiazepine receptor (PTBR) of trout brain was
pharmacologically characterized and pyrethroid interaction with this site
investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain
membranes of rainbow trout; these shared some of the characteristics of the
PTBR of rodent brain (i.e., high affinity for PK 11195...

Crops were grown at the experimental farms using accepted cultural practices within the limits of experimentation or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with two to five replications. Herbicide treatments were applied uniformly with precision plot sprays or granular formulations were distributed...
Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...
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,"...
The bulk of the theory on error control codes has been developed under the
fault assumption of random (symmetric) errors, where 1 → 0 and 0 → 1 errors are
equally likely. In the past few years, several applications have emerged in which the
observed errors are highly asymmetric. This...
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...
