Stocking levels and height growth rates of noble fir and
associated species were measured on 51 clearcut study areas within
the Pacific silver fir zone of the Oregon and Washington Cascades.
Clearcut study areas were approximately 20 years old and had either
planted noble fir or natural regeneration of noble...
In the 1970s and 1980s, there was considerable interest in near-equatorial variability at periods of days to weeks associated with oceanic equatorial inertia–gravity waves and mixed Rossby–gravity waves. At that time, the measurements available for studying these waves were much more limited than today: most of the available observations were...
The theoretical resonant excitation of equatorial inertia–gravity waves and mixed Rossby–gravity waves is examined. Contrary to occasionally published expectations, solutions show that winds that are broadband in both zonal wavenumber and frequency do not in general produce peaks in the wavenumber–frequency spectrum of sea surface height (SSH) at wavenumbers associated...
I. The Effects of Sire Breed, Forage Availability and Weather on the
Grazing Behavior of Crossbred Ewes.
Thirty nonpregnant, nonlactating crossbred ewes, six per sire
breed (Suffolk, Clun Forest, Dorset, Polypay and Border Leicester),
were observed grazing together in a 0.87 ha grass-clover pasture for
six days over a two-week...
A new species belonging to the lichen genus Physconia is described from Alaska and the Canadian and American Rocky Mountains and adjacent forested regions. It is also reported from China, Nepal, India and Siberia. The new species, Physconia labrata, is superficially similar to P. perisidiosa, but can be distinguished by...
This report describes of current research in Artificial Intelligence at Oregon State University. The five areas of active research are ( a) intelligent aids for mechanical engineering design, (b) active experimentation as a method in machine learning, ( c) techniques for combining logic programming and assumption-based truth maintenance, ( d)...
People interested in economic development in rural communities are often faced with the need to estimate impacts of economic changes or to forecast population, employment, business activity, or public service demands.
An economic "tool" that is often used to assist in this task is the "multiplier." This circular is designed...
