The purpose of this research was to determine if
overland flow and sediment production were different in
logged (on snow, frozen soil, and prescribed skid trails)
and nonlogged sites in a Pinus ponderosa Laws.!
Symohoricaroos albus Laws. community in the foothills of
the Wallowa Mountains in northeastern Oregon. To determine...
The absorption, translocation and metabolism of a new
herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were
studied in both peanut and soybean plants. These studies were
carried out on plants of different ages and treated at two rates of
application. The residue content of the plants was also determined
from germination to...
The fungus Verticillium dahliae Kleb. causes a wilt disease of
peppermint, Mentha pipertita L. Propane flaming of peppermint
stubble is widely used to control Verticillium wilt in the Willamette
Valley of Oregon, but little is known about the temperature required
for effective control of the fungus.
The purposes of this...
The primary purpose of this study was to investigate the formal
preparation currently required and desired for teachers of lower-division collegiate courses in public community colleges in the western
United States and to make recommendations for the preparation of
such teachers in Oregon. The identification of the functions of institutions...
The development of a transient electric birefringence (TEB) apparatus for macroparticle characterization is herein discussed. The experimental difficulties encountered were related largely to poor data resolution. Misalignment and strain birefringence in optical components further complicated results. Improved data digitization methods were developed, and precise mathematical models were derived in order...
Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...

The sensitivity of Bacteroides nodosus, causative agent of sheep foot rot, to 24 selected antimicrobial agents was tested. Many contaminants ordinarily associated with foot rot lesions were sensitive to lincomycin while B nodosus demonstrated resistance to this antibiotic. A concentration of 1.08 μg of lincomycin/ml of basal medium optimally inhibited...
