In response to the growing preference for the small family, this study was carried cut to acquire information about women who expect zero, one, or two children. The purposes of the study were: to identify the cultural and socioeconomic characteristics of these women; and to determine which of these characteristics...
The Federal Water Pollution Control Act Amendments of 1972
prohibits the discharge of seafood processing solid wastes into
navigable waters after July 1, 1977. Oregon shrimp and crab processors
must use other methods of disposal for the 15 to 30 million
pounds of solid waste generated annually. The application of...
Development of a performance analysis for propeller type wind
turbines is presented. The analysis uses a strip theory approach
that includes tip-loss and blade interference. A comparison is
presented between analysis and test data. The comparison indicates
that the analysis predicts wind turbine performance to an accuracy
that is within...
This project was designed to test the biological effects of three
levels of dietary protein (12.7, 16.3 and 19.3% CP on a dry matter
basis) on high producing Holstein-Friesian dairy cows. Forty five
second lactation or older cows that showed the potential to produce
over 31.75 kg (70 lbs) per...
This report presents observations from two programs in 1975, WISP and UP-75 to study circulation off Oregon. WISP was a study of the transition between the winter and spring regimes, and UP-75 was designed to determine whether there is a poleward undercurrent along the continental slope during the upwellinq season....
The fish and wildlife resources of the Middle Coast Basin (Fig. 1), their present status, value, limiting factors and water requirements are reviewed in this report. Minimum and optimum stream flow recommendations are presented and field study methods outlined.
The flow recommendations for fish life are primarily for use by...
Chamaecyparis lawsoniana, an extremely valuable timber tree
species, is highly susceptible to a serious, soil -borne root disease
caused by Phytophthora lateralis. Disease outbreaks of epidemic
proportions are continually causing high mortality in natural stands
of the host tree. Practical control measures rely on an understanding
of the many factors...
The present experiment examined children's memory for stereotypic
and non-stereotypic sex role content in their reading material.
Twenty-four male and twenty-four female fifth grade subjects read
two short stories, each depicting a male and female character who
exhibited an equal number of masculine and feminine traits and
behaviors. Results of...
Tomato seedlings were used to assay the population of A.
tumefaciens in artificially contaminated soil. Aqueous soil suspensions
were applied directly to the wounded stem. The bioassay was
used because not all pathologically important physiological strains
of A. tumefaciens would grow on any of the selective media available.
This method...
Two cultivars of tall fescue (Festuca arundinacea
Schreb.) with contrasting growth habits were studied under
field and growth chamber conditions. Fawn, an established
cultivar since 1964, and TFM, an experimental line, were
observed to grow better during spring and fall months
respectively, in the field. Different temperature regimes
of 10/4,...
Results of recent studies on Piagetian cognitive development,
though equivocal, showed that the architectonic of formal operational
schemata is not possessed by a sizeable percentage (up to 52%) of adolescents
and young adults. The purpose of the present study is two
fold: (i) To assess the cognitive levels of a...
Microprogramming has evolved since its introduction in 1951 by Maurice Wilkes. The most significant change that has taken place is the recent growth of interest in user microprogramming. However, user microprogramming is a difficult task because of various complex and intricate features of the host processors. A microprogrammer must be...
The purpose of this research is to design a high level language
(HLL) suitable for microprogramming. A top down design technique has
been adopted which makes the language design process simple and
accurate.
The primitive operations of a high level language for producing
emulators is shown to include special purpose...
Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...
Pangola digitgrass (Digitaria decumbens), Coastcross-
1 bermudagrass (Cynodon dactylon), and Kazungula
setaria (Setaria sphacelata cv Kazungula) were used in a
two-year study at the C.A.M.P.A. Training Center in
Tampico, Mexico. The objective of the study was to determine
the optimum stocking rate during the grazing season
on these species and...
The work upon which this publication is based was supported by funds provided by the United States Department of the Interior, Office of Water Research and Technology, as authorized under the Water Resources Research Act of 1964 and by the United States Department of Agriculture, Forest Service, Pacific Northwest Forest...
At weights of 81.5-90.5 kg, 187 prepuberal crossbred gilts were
subjected to specific environmental stimuli, for up to 17 days, to
determine which stimuli or combinations of various ones would initiate
onset of estrus in prepuberal gilts. The stimuli used were:
movement to new building, mixing or non-mixing of gilts,...
Three provisional species are described as new: Leucogaster
couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida
is transferred to Leucogastef, completing the transfer of all
Leucophlebs species to Leucogaster. L. columellatus is transferred
to Sclerogaster. L. longisterigmatus is synonymized with
L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
Steryl glycoside is synthesized from mevalonate [2- ¹⁴C] in both maturing pea seeds and etiolated pea seedlings. The maturing seed appeared more active than the seedlings for this synthesis. The sugar moiety was identified predominantly as glucose by acid hydrolysis and paper chromatography of the aqueous extract of the hydrolysate....
Laboratory experiments were conducted to study those factors which control the rate at which salts, such as magnesium chloride and sodium chloride, are removed from titanium sponge. The sponge was prepared by reducing titanium tetrachloride with either magnesium or sodium, and the resulting sponge salt mixtures were treated by vacuum...
Instrumentation for rapid, high precision size analysis of silt and sand size particles has been acquired and/or developed by the marine geology group of the School of Oceanography of Oregon State University. A Cahn automatic electrobalance with particle sedimentation accessories is used for size analysis of the silt fraction of...
The Brassicaceae, Mustard Family, is a well marked natural
family, whose tetramerous flowers, tetradynamous stamens, and
distinctive bi- carpellary fruits, clearly distinguish it from related
families. It is a large family of some 3, 000 recognized species and
over 300 genera. Although numerous attempts have been made over
the past...

High protein wheat seeds frequently perform better than low
protein seeds of the same variety. Protein content of seeds can be
increased by management practices, the most important of which is
rate and timing of N applications. The purpose of this study was to
determine the chemical, biochemical and physiological...
Experiments were conducted to determine the effect of environment
and several plant growth regulators on the physiology, quality,
and agronomic performance of snap beans (Phaseolus vulgaris L. )
and spring wheat (Triticum aestivum L. ). The potassium salts of
naphthenic acid and cyclohexanecarboxylic acid, received particular
attention.
Application of potassium...
