A study conducted May 1978-December 1980 determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed 1199km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western Oregon. The CWTD distribution
was not contiguous throughout...
Riparian communities in the southern portion of Malheur National
Forest were intensively studied with the objective of designing an approach for
classifying disturbed riparian areas into units of similar potential. Not all
riparian community types in this portion of the Blue Mountains were sampled
due to time limitations. Some of...
Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
For many years, psychologists have studied
the principles of psychophysics. Recently, cartographers
have been considering psychophysical theory in
color attribute analysis to aid in the design of maps.
An experiment was conducted using the partitioning
method by which the Munsell value scale was determined
to find (R,G,B) coordinates giving equally...
Emissions of oxides of nitrogen from a small (15 kW) turbine generator burning high fuel bound nitrogen fuels were measured by a chemiluminescence method. Kerosene was used as the base fuel and pyridine was added to achieve different fuel bound nitrogen levels. Mixtures of 0.0%, 0.5%, and 1.0% (by weight)...
Indole-3-carbinol (I3C) and butylated hydroxyanisole (BHA), anti-carcinogens
present in the human diet, were tested for their in vivo
and in vitro effect on aflatoxin B₁. (AFB₁) metabolism, and DNA adduct
formation in the rainbow trout. Dietary BHA at either 0.3 or 0.03%
had no effect on the hepatic tumor incidence...
Ankle injuries account for 10-20% of time loss injuries in sports
with almost 85% of these injuries being sprains, the majority of
which occur to the lateral ligamentous complex. With statistics such
as these it becomes important that the Athletic Trainer establish a
method for effective and efficient means to...
