Five forms of chromatin, which represent the in vivo folded forms
of nucleic acid, were isolated and used as the binding substrate for
model intercalating compound, ethidium bromide. For all forms of
chromatin, the affinity, location and structural effects of binding
were examined. On the level of the nucleosome, the...
Plasma membranes from Saccharomyces cerevisiae were prepared by a new procedure involving lyticase treatment of the yeast cells. The plasma membranes were right-side out, closed vesicles of uniform appearance with a sterol to phospholipid molar ratio of 0.365. The thermotropic behavior of these plasma membranes from wild-type yeast and from...
The energy levels of internal waves observed during the
Arctic Internal Wave Experiment (AIWEX), conducted from the
drifting pack ice in the Beaufort Sea, increased as the speed of
the ice drift increased. The possibility of these waves being
generated by moving pack ice with a corrugated under-side is
explored...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
Fluctuating feeder cattle prices have a direct affect on the
revenue variability of feeder cattle producers. Hedging in the commodity
futures market is a marketing strategy which can, if properly used, reduce
the financial risk of feeder cattle producers. If the closing
basis value is known when a hedge is...
The purpose of this study was to examine the relationship between career development and locus of control as
they relate to barriers encountered in career development.
The sample included 144 students in the engineering
program at Oregon State University. The Rotter Internal-
External Scale and the Career Development Inventory (Form...
Gravity measurements made during 1979 and 1980, combined with
existing gravity measurements, provide data for the interpretation
of upper crustal structures relevant to the assessment of the geothermal
potential of south-central Oregon.
West of Upper Klamath Lake, free-air gravity anomalies trend
north-south and average near 35 mgals. East of Upper...
The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...
Adolescent pregnancy is a serious problem which creates social and
emotional consequences for 1 in 10 teenaged girls and their families.
Although the severity of the problem has been well documented in the
literature, few empirical investigations have been conducted to expand
information or to aid in the understanding of...
