There has been no toxicologic proof that the long-term, low-level
exposure of man to chlorophenothane (DDT) is linked with an
increased susceptibility to toxicity or disease. Acute pretreatment
of rats with 75-100 mg/kg DDT has been demonstrated to potentiate
CCI₄-induced hepatotoxicity in that species (McLean and McLean,
1966). Since the...
The role of weather in influencing tourist-recreation visitation
to the Oregon coast during the six-month summer season of May
through October has been investigated by this research. In addition,
the normal day-to-day fluctuations in coastal visitation has been
determined.
Based upon the normal visitation, the tourist-recreation season
on Oregon's coast...
Presents pesticide and herbicide application rates and recommendations, by tree growth stage, for pests that infect fruit trees. Covers apples, pears, and cherries. Provides (1) spray program for nutrients; (2) dilutions table for wettable powder and liquid products; (3) natural enemy impact guide for tree fruit pesticides; (4) illustrated bud...
In the U.S. there are increasing energy demands that require an ever-increasing need for the large-scale use of new energy resources. Specifically, sporadic renewable energy sources are being incorporated into utility energy portfolios. Thus, supporting stationary energy storage technologies are needed to make these renewable sources reliable and feasible for...
This study seeks to explore the relationship between social capital and well-being in the rural Western United States. Mixed methods were employed to understand the concepts from multiple angles, using both profile and process indicators. An econometric approach used profile indicators and relied on data from 414 counties in the...
This study, conducted with the cooperation of the Oregon Comprehensive
Health Planning Agency, Salem, had a threefold purpose:
(1) to identify the role of the physician's assistant (PA) in Oregon,
(2) to provide substantive data for recommendations regarding changes
in PA licensure, and (3) to provide information which may be...
The purpose of this study was to provide a history of the Business
Education and Secretarial Science departments at Oregon State
University. The historical-documentary method of research was
used. Extensive use was made of interviews with those involved in
the school's history. The chronology of history was divided into segments...
This study evaluates the feasibility of retrofitting a rotary
dryer to a hog fuel boiler, using the boiler exhaust gases as the
drying medium.
Two simulation models were developed. As substantiated by experimental
measurement of existing boiler/dryer systems, each model
accurately predicts system performance given site-specific parameters
such as boiler...
The association of hyaluronic acid (HA) into a double stranded
structure has been investigated by circular dichroism (CD)
spectroscopy into the vacuum ultraviolet region. The CD of HA changes
dramatically, monitoring a cooperative transition as the dielectric
constant of an aqueous solution is reduced by adding organic solvents.
This structural...
