An attempt to determine the relationship between the computer,
the computer program exchange organization and today's practicing
civil engineer has just been completed. A questionnaire was used to
obtain information and opinions from 850 selected practicing civil
engineers. Based on those questionnaires reaching their addresses,
a return rate of 81.7...
Creep in wood has been observed since 1833 but only recently
has it been studied quantitatively. The aim of this paper is to study
the time-dependent deflections of Douglas fir, Coast Region beams
in bending and shear modes. The general method of approach used is
that of large scale observation....
The present status of plastics is one of constant change, but
this thesis attempts to focus attention on the state of the industry as of
1967. Beginning with a brief title definition and history of plastics,
the writer proceeds to a discussion on the structural characteristics
of plastics. Under this...
There are several factors which affect the cost and efficiency
of a structure. The most important and basic factors are: the predominant
stress, the way the structure carries the loads and the
shape of the structure.
The structures in which the predominant stress is not bending
have been chosen to...
The study of the vegetation of one of the natural coastal
prairies in Oregon was undertaken for the purpose of describing
some of its synecological features. Specific objectives of the study
were to describe certain plant assemblages in the study area, present
phenological relationships on some of the assemblages, and...
Seven winter wheats were evaluated for plant height, the components
of yield and yield in a diallel cross at Pendleton, Oregon and
Lind, Washington. An additional parent was added to the diallel cross
at Pullman, Washington. Two levels of nitrogen and five replications
were utilized at each of the locations....
This study was designed (1) to determine if selected family
oriented factors influence student wives' housing satisfaction, (2) to
determine which housing factors have the greatest influence on the
student wives' satisfaction with their housing, (3) to determine which
housing factors influence most the selection of married student housing,
(4)...
Acid and alkaline phosphatase was localized histochemically in the intestinal epithelium and excretory duct respectively in fresh
frozen sections of Fasciola hepatica. Polyphenol oxidase was
localized in the vitellaria, vitelline ducts and egg-shells. The distribution
and nature of esterases was examined histochemically. Acetyl-cholinesterase
was observed in the tegument, neural ganglia,...
Electrocardiograms from 12 compressed male (CM), 16 compressed
female (CF), ten synthetic compressed female (SCF), nine
brachycephalic female (BF), and 15 dolichocephalic female (DF)
dwarfs from Davis, California, taken in the scapular lead S-II (prescapular
position positive and right forelimb negative) were analyzed,
The data on dwarf electrocardiograms were compared...
The amine extraction process is evaluated for pulse column
operation. A 0.1 M solution of Primene JM-T (a commercial mixture
of tertiary-alkyl primary amines) in a kerosene-base diluent is
the extractant for thorium feed in aqueous acidic sulfate solutions.
Equilibrium isotherms at room temperature are presented at
aqueous acidities of...
Pyridoxal phosphate is a coenzyme in about 50 known enzymatic
reactions. A simple and accurate method for the determination of
pyridoxal phosphate would be desirable because it could provide a
means to assess the nutritional status of vitamin B₆ in the human.
The cyanohydrin methods to determine pyridoxal phosphate appear...
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 tests could be
discerned to facilitate seed testing work.
Mechanical damage was induced by threshing,...
The present investigation was designed to test two major hypotheses
and five sub-hypotheses. The two major hypotheses were:
(1) Parental models influence the shaping of children's responses to
frustration, and (2) There is a positive relation between parental
consistency in responses to frustration and children's imitation of
parental responses. Three...
Previous work has shown that diuron (3-(3, 4- dichlorophenyl)-1,
1-dimethylurea) is less toxic to fall-planted wheat than to wheat
planted in the spring. Diuron has been a significant factor in increasing
yields of winter wheat grown in Oregon's Willamette Valley.
The influence of several selected environmental factors on diuron
toxicity...

Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
Field, greenhouse, growth chamber and laboratory experiments
evaluated factors affecting establishment, survival and production
of birdsfoot trefoil (Lotus corniculatus L.) and alfalfa (Medicago
sativa L.)
Field studies investigated the effects of a barley companion
crop, seedling year harvest management and nitrogen and phosphorus
fertilization upon stands, survival and subsequent production...
This report presents a summary of the principal geologic and physiographic features of the upper part of the Snake River Canyon between Oregon and Idaho. The area discussed extends from Farewell Bend near Huntington, Oregon downriver to Granite Creek 6 miles below Hells Canyon Dam, a distance of 94 miles....
This report is one of a series issued in cooperation with the Air Force-Navy-Civil Committee on Aircraft Design Criteria under the supervision of the Aircraft Committee of the Munitions Board. Information reviewed and reaffirmed May 1953, June 1959, and 1965. Date of original report November 17, 1944.
A study of the immature stages of the subfamily Troginae in
North America was conducted from the spring of 1963 through the
spring of 1965, Larvae of Trox and Omorgus were easily reared in
the laboratory, but all attempts to rear the larvae of Glaresis were
unsuccessful,
The suberosus group,...
The objectives undertaken in this study were:
1) to develop means of identifying the immature stages of
the known insect predators and parasites of the Douglas-fir beetle; 2) to investigate the possible distribution,
spatially and/or temporal, of the known insect predators
and parasites in standing trees infested by the Douglas-fir...
The foundation upon which any cooperative rests is the economic need for it as a business enterprise. The existence of such a need cannot by itself provide the basis for a thriving cooperative. Not only mus.t the need exist, but the members or the promoters must through realistic and diligent...
The purpose of this study was to investigate the relationship
between specific mother-child interactions and selected aspects of
language development in "disadvantaged" children.
The subjects were 19 preschool children in a summer Head
Start program in Denver, Colorado. Their ages ranged from four
years-nine months to five years-seven months. Eighteen...
The purpose of this study was to compare the level of behavioral
understanding of preschool children of mothers who had observed in
the nursery school with the level of behavioral understanding of
mothers who had not observed. "Behavioral understanding" was defined
as a mother's degree of awareness of the factors...
This study was designed to test the relative effectiveness of
teaching Writing 111 at Oregon State University by closed-circuit
television as compared with conventional classroom procedures; the
hypothesis was that the students taught by television (the experimental
group) would achieve as well as the students taught in conventional
classrooms (the...
The purpose of this study was to compare the performance of
hosiery made from a new fiber, polypropylene, with the performance

Ion exchange chromatography methods which have been
developed in recent years appear to offer a sensitive technique that
can be utilized very advantageously in studies on various proteins
and their properties. The application of such a procedure for the
successful fractionation of bovine sarcoplasmic proteins should stimulate
interest and research...
