The black and white pattern formed when an individual word is
printed on a page was analyzed by the Fourier transform. The Fourier
transform produces a sequence of sinusodial functions, usually called
spatial frequencies, whose amplitudes depend upon the particular
pattern analyzed. These amplitudes were examined to determine if the...
A decade after the School of Education at Oregon State University adopted a spiral model of curriculum for teacher education,
a study was conducted to determine if Instructional Media, one
thread of that model, was spiralled in the curriculum.
A survey was conducted of graduating seniors, using a questionnaire to...
Fourteen multiparous Holstein cows were paired by stage of
lactation and previous years milk yield and 14 Holstein first-calf
heifers were paired by stage of lactation. One member of each pair
was assigned to a 24L:OD or a 18L:6D photoperiod for 16 wk during
winter 1981 (Experiment 1). A similar...
Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...
Pineal hydroxyindole-0-methyltransferase (HIOMT) activity
was monitored over a 24 h period under three different photoperiods,
16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three
groups of fish HIOMT activity was high' during the dark portion of the
photoperiod in comparison to activity during the light portion....
'Jubilee' sweet corn was grown under conventional tillage and
strip tillage in 1982 and under conventional tillage, strip tillage
and no-till culture in 1983. Effects on soil temperature,
stand establishment, plant development parameters, overall yield,
yield components, and water use efficiency were measured.
In 1982, conventional tillage appeared to have...
Field experiments were conducted in 1981 and 1982 to
develop a method for using remotely measured leaf canopy-air
temperature differences (stress-degree-days (SDD)) to
schedule irrigations and to evaluate the effects of
differential irrigation on snap bean cultivars, 'Oregon
1604' and 'Galamor'. Effects on soil water potential
(SWP), leaf water potential...
The aim of this study was to determine whether
counselors in training chose various specialties due to
their level of self-concept, counseling style, and
gender. It was hypothesized that there would be a
significant difference in self-concepts, counseling
styles, and gender between individuals who chose family
counseling and those who...
