The ecological interrelationships of mites occurring in
and near the Hood River Valley, Oregon, pome fruit orchards
were investigated to determine the possibility of an integrated
control program using the species already present.
Survey sampling...

The purpose of this study was to make a preliminary
investigation of the productivity of some of the soils
within the Willamette catena under different systems of
soil management. The study was carried out at four experimental
sites near...

This thesis presents the results of sampling experiments
investigating the properties of estimates of the
mean life of a radioactive source in the presence of a
constant unknown background.
An iterative estimation procedure is used where the...

This thesis describes the adder to be used with the Galaxy computer, which is to be constructed at Oregon State University.
The need for faster, more reliable adders is discussed
along with previous adder designs related to the
Galaxy Fast Carry...

The effects of mechanical damage, insect infestation and
storage conditions on seed viability of spring wheat were studied by
three known tests, laboratory germination, greenhouse growth, and
tetrazolium staining, so that the relationship of these...

This paper presents an investigation of the power needs and
impedance-matching techniques involved when heating small charges of
relatively high-resistivity semiconductor materials. Topics of discussion
also include a brief section on the...

The indicated sum of a real scalar and a real or imaginary
vector is called a scator. Either the scalar part or the vector part
may be null. Scators generalize the complex variable to n-space.
The algebra of scators is not generally associative...

This study discusses important aspects of the ocean which
should be considered in the design of a sewage outfall system; conditions
are restricted to those of the Oregon coastal area. They include
predominant currents, upwelling tendencies and...

White muscle disease or muscular dystrophy of sheep is a selenium
responsive malady common to many areas with an inherent natural
deficiency of selenium in the forage. The disease can be prevented in
lambs by adding trace amounts (approximately...

The Tailed Frog Ascaphus truei, the only species in the
family Ascaphidae found outside New Zealand, is a common inhabitant
of the mountain streams of the Northwestern United States and
British Columbia. The anatomical peculiarities of this...

The fish of Suttle Lake, Oregon, have been found to harbor
an acanthocephalan parasite, which lives attached to the mucosa of
the intestine. Between July 1961 and January 1963, several hundred of
these fish were exarnined and nearly every one was...

Application of herbicides to the soil has become an important
factor in the production of row crops. Economic production
of sugar beet (Beta vulgaris), an important row crop, requires
efficient methods of weed control.
Two experimental herbicides,...

Eola rasp leaf of cherry was first described by Milbrath and
Reynolds in Oregon in 1961. Dr. Cadman of the Scottish Horticultural
Research Institute suggested that this disease was incited by a strain
of tomato ringspot virus (TomRSV), but since...

The concept of a Critical Path Scheduling Tableau is introduced
as an integrating tool for solving industrial engineering problems
involving the application of transitive graphs.
The Tableau is a combination of a precedence matrix and a
boundary...

A configuration-interaction determination of wave
functions has been made for the ²S and ²P states of lithium,
and for the ¹S and ³S states of the lithium ion.
Two 1s, one 2s, one 3s, and two 2p functions served as
starting functions for all four...
