Sediment transport in a gravel-bottomed stream located in the Oregon Coast Range was studied to determine the effects of a single
layer of large particles (the armour layer) located at the surface of the bed material. The bed load transport system was studied jointly with suspended sediment transport to understand...
Twenty-five gabion-type structures across the main stem and
tributaries of the Siuslaw River in the Oregon Coastal Range, installed
to expand the available spawning area for fish, were investigated for
their ability to perform gravel control functions such as trapping bedload
carried by the stream or holding gravel placed behind...
The purpose of this research was to determine the effects of a
college human sexuality course upon sex knowledge, attitudes toward
sexual behaviors of non-significant others, and attitudes toward the
sexual behaviors of self and spouse. In addition, the study sought to
investigate the relationship between knowledge gain and attitude...
Intensive forest management requires efficient logging techniques
to remain economical. Commercial thinnings and shorter
rotations increase piece count inversely to piece size. Continued
research aimed toward effective log handling processes is essential.
The purpose of this study was to evaluate one case of a self-loading
log truck (integral loader and...
Red-osier dogwood plants were grown outdoors in a lathhouse
and under two temperature regimes in growth chambers to determine
the time of vegetative maturity, the transition between summer and
winter dormancy. Xylem water potential (XWP), tissue moisture
content, ethylene and ethane production, and electrical impedance
were used to try to...
A rapid gas liquid chromatographic method was adapted to processed
Dungeness crab for the determination of basic and neutral
volatiles. Methylamine, dimethylamine, and trimethylamine were
measured in processed Dungeness crab for the first time. Generally,
the range for trimethylamine was 42 ppm for frozen crab to 700 ppm
for iced...
Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...
This paper presents an extension of Hubert's incidence axioms to n dimensions and uses these and his order axioms to prove several theorems. We prove extensions of Pasch's Axiom, the Crossbar Theorem, and Desargues' Theorem for n dimensions. A non-Euclidean model is presented and proved to satisfy the axioms. In...
The free amino acid content of the intracellular pools in higher
marine fungi was determined by thin-layer and gas-liquid chromatography.
The organisms investigated include:
Ascomycetes; Nais inornata, Leptosphaeria oraemaris, Corollospora
maritima, Haligena elaterophora, Halosphaeria mediosetigera, Halosphaeria
appendiculata, Halosphaeria quadriremis, Lignincola Laervis
and Remispora hamata, and Fungi Imperfecti; Zalerion maritimum and...
