In recent years considerable work has been done in the development of improved logging machinery. The word improvement may bring to mind entirely new or improved systems which offer the logger greater mobility and efficient use of manpower. Logging has generally been labor intensive, however, "The need to achieve greater...
The Weather Radar Set An/CPS-9 at McCulloch Peak,
Oregon, provided data of changes in radar precipitation
echo patterns in the vicinity of Marys Peak. Echo heights
studied from data collected on 14 March 1963 averaged nearly
the same upwind, directly over Marys Peak, and downwind.
For the data of 28...
This paper analyzes the theory and performance of a
Schottky barrier diode detector used over a frequency range
extending from a few kilohertz into the gigahertz region.
The process of large signal rectification is analyzed with
the simplified detector circuit. Phenomena which can
affect the rectification process at high frequencies,...
Bioturbating infauna significantly modify reaction and transport processes in permeable sediments, though most studies to date are limited in the scope of species examined. We conducted a comparative field study measuring density-dependent effects of six common bioturbating species on porewater advection and biogeochemistry, across three intertidal permeable sediment habitats. The...
Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua...
White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, results in severe losses in the production of common bean, Phaseolus vulgaris, especially snap bean varieties. Advanced backcross QTL analysis was used to identify quantitative trait loci for resistance to white mold in an interspecific cross of P. vulgaris and P....

The advanced backcross-quatitative trait loci (AB-QTL) breeding method was employed on snap bean (OR 91G x PI433251B) and dry bean (M0162 x PI433251B) interspecific populations to transfer resistance QTL from resistant donor parent Phaseolus coccineus into P. vulgaris. For OR 91G x PI433251B, analyses produced nine linkage groups corresponding to...

To determine the effect of bud pollination, compared to pollination
of open flowers and crossing, on field characteristics of broccoli progenies,
an experiment was conducted in 1974 and 1975 at Corvallis, Oregon.
Single plants of 55 broccoli lines were pollinated, using four methods,
i.e. bud pollination (BP), open flower pollination...
Allocentrotus fragilis (Jackson) was obtained from six stations
at depths of 100 to 1260 m on the continental shelf and upper slope off
Newport, Oregon.
Ages and growth rates of A. fragilis were determined by two
methods: 1) A procedure was developed to make growth zones of the
skeletal test...
