The goal of these experiments was to ensile combinations of shrimp or crab waste
with perennial ryegrass straw and analyze it for silage quality and ruminal degradability.
The rapid deterioration of seafood wastes required initial preservation prior to ensiling
to minimize odor production and protein breakdown. Eight experiments were conducted...
The effect of frozen storage time on the composition
of the cell wall polysaccharide (CWP) of muskmelon (Cucumis
melo) cultivars at different stages of maturity was investigated.
Changes in composition, firmness, drip loss, and
color of Cantaloupe and Honey Dew melon flesh were determined
at three stages of maturity and...
Oregon educational reform efforts are moving ahead with the support of legislation,
business and industry, and education. There has been little apparent consideration given to
the readiness of tenth graders to make career choices even though the research in the area of
career maturity indicates that students at this period...
This article presents a set of recommendations that promote a more nuanced, meaningful accountability policy for English learners in the next authorization of the Elementary and Secondary Education Act. The authors argue that the ESEA reauthorization must strengthen the law's capacity-building purpose so that federal, state, and local leaders support...
Ecological relationships between D. coccinellae and its coccinellid hosts were examined in the Willamette Valley, Oregon, in 1982. The distribution and relative abundance of seven species of coccinellids from eight collecting sites were monitored to determine percent parasitism by D. coccinellae on a spatial and temporal basis. Host size and...
Hand-defoliation was evaluated for its ability to
simulate herbivory by cinnabar moth larvae, Tyria
jacobaeae (L.) (Arctiidae) on the weed tansy ragwort,
Senecio jacobaea L. (Asteraceae). The evaluation was done
on a field population of flowering ragwort, for three
different timings (early, middle, and late season) of
damage.
In the...
A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...
Coarse resolution imagery, such as that produced by the MODIS instrument, poses the challenge of estimating sub-pixel proportions of di erent land cover types. This problem is di cult because of the variety and variability of vegetation within individual pixels. This thesis describes and compares two existing algorithms for estimating...
