The seasonal biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris), was studied to improve its management in Mid-Columbia area sweet cherry orchards. Overwintering OBLR larvae began to emerge from hibernacula at bud stage 2 (side green). Most overwintering larvae emerged from hibernacula within three weeks of first bud swell and...
In the months preceding the 2016 presidential election and during the Trump presidency, rhetoric, composition, and communications scholars expressed an urgent concern about the threat that Trump and his political affiliates posed to the status of truth in political life (McComiskey; Rice; Harsin; Cloud). However, the conversations surrounding the discipline’s...
An eigenvector analysis of the velocity-temperature correlation
matrix is applied to clear-air turbulence measured by aircraft in the
Bora. The eigenvectors are identified with the main eddies of the
turbulence. This study attempts to infer the three-dimensional
structure of these eddies. The results are compared with turbulent
structures in the...
The influence of variety, plant population, and planting date on
corn silage production was studied at Hyslop Agronomy Farm,
Corvallis, Oregon. The corn plants were grown under irrigation with
300 pounds per acre of 16-20-0 (N-P₂0₅-K₂0) and 240 pounds of urea,
providing a total nitrogen application of 158 pounds per...
In the last 30 years, birdsfoot trefoil (Lotus corniculatus L. )
has been recognized as a great potential source of forage. Since the
1930's, many studies have been reported in relation to birdsfoot
trefoil characteristics, including some directly related with the
association between seed yield and its components.
The purpose...
This investigation studies the relationship of the reflectivity in
the radar beam depicted by the radar echo patterns to the computed
reflectivity at surface observing stations under the radar beam.

Routine studies of bacterial fatty acid and lipid composition,
made possible by recently developed techniques, have brought about
an increasing interest in the physiological significance of these
compounds. The purpose of this study was to characterize the fatty
acids of the vegetative cells of Clostridium botulinum 33A, as the
first...
