Digital filtering can be done on a limited scale using an
IBM 1620 digital computer. A computer program has been written
to aid in the design of digital filters by computing the power spectrum
of sampled time data. The power spectrum analysis...

The purpose of the study was to determine an emergence
rhythm, its period, and the developmental stages susceptible to
emergence synchronization in the leafcutter bee Megachile rotundata
(Fabricius). An attempt was made to determine if an oxygen...

One of the most serious problems confronting modern America
is the efficient and rational utilization of the recreation resource base,
not only in terms of present demands and needs, but future as well.
The resource manager, in the past, has had...

This paper describes a technique for separating the
two signal voltages which are necessary for balancing an
ac impedance bridge from its detector output voltage.
The technique is unique in that the necessary information
is derived from...

Ten helminth-free sheep were given two doses of 10,000,
X-irradiated, H. contortus, third stage larvae 30 days apart. These
animals and a group of ten non-vaccinated sheep were challenged
with 50,000, normal, H. contortus, third stage larvae 60...

A survey of federal and state agencies was conducted to determine
the future need for water-quality data. This survey was used
as the basis for constructing a water-quality data aquisition system
applicable to any river basin. This study outlines...

The movements of a population of adult sockeye salmon
(Oncorhynchus nerka) were followed in a small tributary of Brooks
Lake, Alaska until spawning was nearly complete in 1963. The objectives
of the study were to describe the movements of sockeye...

Heat transfer from the inner wall of an annulus to subcooled
water in turbulent parallel flow was studied. The inner core of the
annulus consisted of wires varying from 0.0019 to 0.0197 inch in
diameter. The outer tube consisted of a 1.01 inch...

Merk's series solution to the momentum equation for steady
two-dimensional or axisymmetrical constant-property laminar
boundary layer flow was examined. Solutions were obtained to the
differential equations associated with the second term in the...

Mitotic activity in the vascular cambium was determined from
ten samples from a single internode in each of four Douglas-fir
[(Pseudotsuga menziesii (Franco.) Mirb.)]trees. Counts of interphase and mitotic nuclei from nine cores in each sample...

This project was initiated to determine the incidence, distribution
and species of fish affected by Ceratomyxa shasta in Oregon
waters. Returning adult Pacific salmon and steelhead trout were
chosen for the survey because they were known to be...

Voltage scanning coulometry was used to study the effects of
electrode surfaces and metals on the electrochemistry of the ferric-ferrous couple and the silver ion-silver metal couple. The analytical
technique called voltage scanning coulometry is...

Characterization of the enzymatic activity of the ionocyte
(mitochondria-rich cell) in the gill epithelium of Oncorhynchus
tshawytscha was explored.
1. A method for estimating the enzymatic activity per cell for
tissues is described.
2. The DNA...

Wheat is an important cereal crop in the Willamette Valley of
Oregon and the stiff-strawed, high-yielding varieties are the predominant
types grown. Observation of the effect of seeding rates
on the yield and yield components are useful in...

Three features of small-molecule photoelectron spectroscopy are considered (1) The atom from which a photoelectron
is emitted must have a recoil momentum equal to that of the emitted electron. This is shared among the various modes
of motion of...

The objective of this study was to investigate the low seed
germination of 12 varieties of Oregon grown monogerm sugar beet,
Beta vulgaris L., using several methods to determine the germination
potential. The methods were: (1) X-ray radiograph...

Because of the potential elevated-temperature applications
of high-purity vanadium in nuclear reactors an
investigation was conducted to determine the effects of
nuclear irradiation upon the properties of the pure metal.
The results of this...

An examination was made of some reactions involving a transfer
of carbon from boron to carbon. In the case of the reaction of
a C[subscript n] alkylorganoborane with dichlorocarbene the intermediate was
a C[subscript n]₊₁ chloroalkylorganoborane....
