Seventy-two species of Blennocampinae in 21 genera and six tribes
are known from the Nearctic region. The adults and known larvae of
all species and genera are keyed, described and illistrated. A
definition of the subfamily, a review of previous work, a table of
host-plant associations, and a discussion of...
The distribution of particles in the Eastern Pacific Ocean was
investigated from 2 January to 14 February, l969, on the YALOC-69
cruise of Oregon State University. The size distributions were well
fitted by the two-parameter Weibull distribution function, with a
predominant number of them nearly exponential in distributional
shape. Although...
This thesis reports a portion of a general ecological study of
a stream under conditions of controlled flow and low levels of organic
enrichment. It is concerned with the effects of experimental variations
of light intensity and concentration of soluble organic enrichment
imposed on seasonal variations of temperature and total...
Samples of benthic algae were collected from the Metolius River
of central Oregon at two-week intervals between April 15, 1967 and
March 9, 1968. Species of filamentous algae and diatoms present
were recorded for every sampling station on each sampling date.
Permanent mounts of diatom frustules were prepared.
This sampling...
A quality problem that frequently occurs with frozen green beans
is the sloughing of the skin (epidermal tissues) of the cooked, ready-to-
serve bean pods. It was found that by giving the beans a pre-blanch
(relatively mild heat treatment) prior to the blanch treatment normally
used for frozen green beans,...
An impounded estuary was employed to study primary productivity, community respiration, and community structure as they
related to seasonal and temporal succession, salinity, and water
temperature. Plankton metabolism was studied by means of the
light-and dark-bottle technique. Benthic community metabolism
was determined by using the "diurnal oxygen curve" method.
Four...
The purpose of this study was to answer three questions in
terms of learning methodology: (1) Is the inductive or deductive
approach more effective in teaching phonic generalizations to second
grade children? (2) Is the inductive or deductive approach more
effective in promoting retention ability after a three week interim?...
Raw and biologically stabilized Kraft mill effluents were introduced
into laboratory artificial streams at a ratio of 15 ml per liter
of water over a two year period. Effluent from the stabilization pond
of a second mill was introduced at concentrations of from 5 to 40 ml
per liter of...
The purpose of this study was to investigate the effects of
logging on the productivity, structure and biomass of a periphyton
community developed in mountain streams. The three streams used
in this investigation were located in the coast range of Lincoln
County, Oregon. They were selected for similarity of habitat,...
The rate of the C¹⁴0₂ release from glucose, specifically labeled
with C¹⁴ at 1, 2, 3+4, and positions, was used to study the relative
participation of pathways of glucose catabolism in red beet slices.
Evidence was obtained which indicated that in mature red beets glucose
was catabolized mainly via glycolysis-tricarboxylic...
Purpose of the Study
The basic purpose of this study was to examine the attitudes and
opinions of community college personnel toward faculty involvement
in policy formulation.
Procedures
The statistical and subjective data for this study were obtained
from two major sources. (1) A statistical questionnaire was
developed to identify...
The primary purpose of this study was to investigate the formal
preparation currently required and desired for teachers of lower-division collegiate courses in public community colleges in the western
United States and to make recommendations for the preparation of
such teachers in Oregon. The identification of the functions of institutions...
Food lipid systems are very complex and so is oxidative
degradation that render them unpalatable for human consumption.
The significance of lipid degradation and the key reactions involved
have been thoroughly studied and are well understood today. This
is not true, however, of the secondary products of the autoxidation
reactions....
A study of the population ecology of Columbia River fall chinook
salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt
to determine the cause of a serious decline in this run which occurred
in the early 1950's. Fluctuations in abundance of major salmon runs
the North Pacific were examined to...
The 13th Annual Northwest Traffic Engineering Conference and the 1960 Annual Northwest Road Building Conference this year have been combined to give a broader concept of the field of highway engineering to persons interested in both phases. Future conferences will alternate as before between the States of Washington and Oregon....
