The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of...

The public health and economic significance of rapid acid production
by lactic streptococci in controlled dairy fermentations is well
known. However, the fast acid-producing characteristic of these organisms
is not stable, and cultures of fast...

Parasites and pathogens influence the size and stability of wildlife populations, yet many population models ignore
the population-level effects of pathogens. Standard survival analysis methods (e.g., accelerated failure time models)
are used to...

The force, temperature, and time relationships were
investigated by using oscilloscope measurement techniques. Force was measured using a strain gage and the dynamic
response recorded with a polaroid oscilloscope camera.
Temperature was measured...

Studies were conducted under controlled conditions in order
to observe the resulting survival patterns in solid crabmeat of
Salmonella typhosa, Salmonella paratyphi B, and SaImonella wichita
following individual exposure to various doses of gamma...

Experiments were conducted to determine the effects of feeding
sulfamethazine to chinook salmon (Oncorhyncus tshawytscha, Walbaum)
as it is used in the Oregon Moist Pellet diet (OMP) for control of
bacterial infections and to compare this drug...

The influence of pH (titration method) and of salt concentration
and drying (drying method) upon the formation of synthetic AI, Fe,
and Mg interlayers in montmorillonite and vermiculite was investigated.
Interlayer formation was evaluated by X-ray...

Objectives of this investigation were two-fold: (l) to determine
crested wheatgrass production on selected range sites and (2)
to evaluate present and potential production on public and private
lands in the study area. Field studies were carried...

Eleven species of Mononchidae Chitwood, 1937 were
found among the nematodes separated from 48 soil samples
in Thailand and sent to Oregon State University. Six
species are newly described and illustrated including
Iotonchus bangkokensis, Iotopchus...

Thermal decomposition of several di-p-toluenesulfonylhydrazones
was studied. It was found that the carbene decomposition
of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone
gave two products resulting from
rearrangement. One was...

Precipitation occurrence in three winter periods and three
summer periods is examined for two Oregon stations: Seaside and
Squaw Butte. The winter periods are January, February, and the
interval January 15 to February 20. The summer periods are...

Oxides of nitrogen are a concern as effluents to atmospheres
because they participate in photochemical reactions which produce
smog, because they attenuate sunlight which gives the atmosphere a
reddish brown cast, and because of their toxic...
