The feeding habits of the Dover sole and rex sole (mainly juveniles) and of slender sole and Pacific sanddab were investigated at seven stations on the continental shelf off central Oregon. Dover sole had a catholic diet, feeding on a large variety of infaunal and epifaunal invertebrates. The composition of...
The effects of mold level (Botrytis cinerea), processing method (fresh, individually quick frozen (IQF), frozen sugared sliced (FSS), freeze dried (FD), canned, and preserves), and maturity (underripe, normal, and overripe) and strawberry volatiles were analyzed by gas liquid chromatography (GLC) using on-column entrainment of headspace volatiles in aqueous extracts. Computerized...
The photochemical reaction between O⁻ ions and F centers
was investigated. The activation energy was determined by the
Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K.
The diffusion of alpha centers towards the oxide ion was eliminated
as the rate limiting step and the low trapping...
Sea tide heights predicted one year
in advance are manipulated to give accelerations
in centimeters per second per kilometer for the
distances San Francisco to Humboldt Bay and
Humboldt Bay to Astoria. Comparison of these
accelerations to various earth-moon-sun lineups
shows the accelerations are controlled by the
29.53 day lunar...
The identification and mapping of surface cover types
within Crater Lake National Park, Oregon, has been effectively
completed through the utilization of LANDSAT digital
data and NASA U-2 color infrared aerial photography. Classification
of LANDSAT data for surface cover type identification
and mapping was accomplished through use of the
Interactive...
A statistical analysis of extreme chinooks in Montana as they
relate to large scale atmospheric circulation changes is the subject
of this thesis.
A mean chinook situation was identified which indicated that a
critical pattern of the surface flow always contained a Polar or
Arctic airmass which overspread the prairie...
Several empirical formulas that may be used to estimate available
chilling are presented in this study. Many climatic parameters
were considered in the derivation of these formulas. One equation
employing only maximum and minimum temperatures had a coefficients
of correlation (R) and R² values of .978 and .957, respectively. This...
The feasibility of utilizing LANDSAT MSS data in assessing surface cover types and areal extent of clearcut and shelterwood cut harvest sites in southern Oregon was investigated. The research utilized extensive 'ground truth' information to evaluate the LANDSAT data. A three faceted ground truth collection scheme analyzed 1) U.S. Forest...
