A time and energy budget was constructed for a population of
dippers (Cinclus Mexicanus) in the Cascade Range of Oregon during
winter. A total of 12,202 point observations of activity were made
from nine observation blinds from 19 November 1973 to 10 February
1974. Approximately 50 percent of all observations...
All attempted synthesis of perfluoroalkyl boron bonded groups
have resulted in the formation of boron-fluorine bonds from the
probable decomposition by α-fluorine transfer. The substance alkali
metal di-n- butylborate (I) has been identified as the potassium derivative
by its reaction with di-n-butylboron chloride and isolation of
potassium chloride. The reaction...
The morphology and genesis of soils of the Willamette series
and of some Willamette-associated soils and their relationships to
geomorphic surfaces were studied in an area near McCoy, Polk
County, Oregon. Influences of regional extent, such as climate and
parent material, were related to the soils and landforms. The soils...
The land tenure system in the United States contains a variety
of tenure types. A major characteristic of this tenure system is the
continual change of tenure types within a given region. As these tenure
types change, problems of a cultural, economic, and legal nature
are created and interact with...
An Ls-isocitrate:NADP oxidoreductase has been isolated and
purified from embryonic chicken liver. The enzyme was purified
200 fold by means of ammonium sulfate fractionation, gel filtration
chromatography on Sephadex G-200, ion-exchange chromatography
on Bio-Gel CM-100 and adsorption chromatography on hydroxylapatite
gel.
The purified enzyme was nearly homogeneous as determined
from...
For over a hundred years, analysts have been concerned with
the static and dynamic behavior of flexible cables. Hanging,
towing and mooring cables have been extensively examined but little
work has been done in the area of the anchor deployment problem. In
the anchor deployment problem, a mooring line is...
The proposed Santiam Bar Natural Area Preserve
is located at the confluence of the Luckiamute, Santiam,
and Willamette Rivers in Polk and Marion Counties, Oregon,
It is situated on a peninsula supporting riparian and lower
terrace vegetation and associated wildlife. Former use
included forestry and agriculture. Present and proposed use...
An inexpensive method for calibrating an infrared analyzer to measure varying ranges of carbon dioxide partial pressures (Pco₂) is described. A discussion is made of the hydrographic (temperature, salinity, and sigma-t) and chemical (dissolved oxygen, AOU, Pco₂ pH, and nutrients) variables that were observed along the Newport hydrographic line in...
The purposes of the study were twofold: (1) to compare selected
personality traits of male and female interscholastic and intercollegiate
athletic coaches with standardized norms for personality
traits established for all men and women, and (2) to compare personality
traits of interscholastic male and female athletic coaches with
the personality...
