The retirement center is the new pattern of settlement in
Oregon. A few years ago there were no modern living accommodations
in the state especially designed for people in the retired category.
As to July 1966 development organizations have thirteen centers
in operation and over 4,000 people are in residence....
This thesis
is concerned
with the
problems
which
need
consideration
when
designing
a
nanosecond
pulse
generator
having
a
repeatable
pulse
width
and
amplitude
output.
The
basic
circuit
is
first
presented
and
analyzed
and
the
reasons
for
wide
variations
in
pulse
width
with
replacement
of
transistors
are
pointed
out.

A study was undertaken in the Marys Peak watershed with the
following objectives. First, a classification of the major plant communities
was carried out. Second, some of the ecological features
of Acer circinatum that account for its distribution within these
communities were determined. The following plant communities
are described:
Corylus...
The Pacific Coast form of Douglas-fir in natural forest succession
is an intermediate species thriving in the Coast Range and
Cascade Mountains of the Pacific Northwest. This species constitutes
26 percent of the standing timber in the United States, and 24 percent
of the nation's annual timber harvest. Characteristics of...
Temporal and spatial patterns of daytime cloudiness in the
Willamette Valley of Oregon were studied by utilizing monthly and
daily sky cover data published by the U. S. Weather Bureau for the
Portland, Salem, and Eugene stations. The 15-year period, 1949
through 1963, was selected as the maximum reliable period...
An attempt was made to demonstrate isozymic forms of esterase,
MDH, LDH and GPDH and the variation in enzyme pattern with increasing
age in the thoracic muscle, appendage muscle and hemolymph
of the American cockroach, Periplaneta americana. Sampled specimens
of both sexes were aged one through seven days, two weeks...
The purpose of this thesis is to examine the problem of the
increasing competition between recreation and irrigation at Wallowa
Lake. Originally Wallowa Lake was an abundant source of fish for
the Indians but the advent of irrigation in the area by the early settlers eliminated the blueback salmon (oncorhynchus...
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 content per cell for nucleated erythrocytes (O. tshawytscha) was determined to be 9.47 x...
In view of recent developments in large-scale, complex digital systems, it is of interest to broaden the study of two-leveled logical systems to the study of three-leveled systems. This paper introduces the ternary logic system and develops a design approach for ternary digital systems that is based on familiar binary...
The merits of the photoelastic coating technique as applied to
wood were evaluated. Comparative tests were made on 12 nominal
two-by-four Douglas Fir boards. The object of these tests was to
determine the limitations of this technique, such as accuracy and
complexity of experimental procedure. Correlation of the experimental
results...
