Due to the present trend to utilize both virtual memory and
paging for the implementation of storage for large-scale computer
systems, it is of interest to analyze the pertinent parameters
associated with the operation of a paging system. This paper
describes the paging process and determines the effect of variations...
During the summer of 1967 a fertilizer survey was conducted
to determine the nutrient status of peppermint fields, the nutrient
concentration of plant tissue and the oil content of peppermint in
Oregon.
Plant and soil samples and the field's fertilizer history
were collected from cooperators in
Oregon's peppermint growing
areas...
The objective of this study was to examine the transpirational
behavior of Douglas-fir seedlings from two origins,, each grown in
two environments, and subject to a range of moisture stress. Forks
and Goldendale, Washington were the mesic and xeric seed origins
respectively. One-half of the seedlings from each origin was...
A study of the effect of mixing on the oxygen uptake rate of
estuarine bottom deposits is presented. The method of study involved
the mixing of samples of bottom deposits with the overlying water to
result in concentrations of suspended matter in the same order as
observed in the estuary....
The effects of an 11-week jogging program on the plasma lipid
fractions and clotting time of 19 late adolescent males (18 to 19
years) were investigated. Total lipids, triglycerides, total and free
cholesterol, phospholipids, non-esterified fatty acids, and clotting
time of plasma were determined. Statistical analysis was applied
to the...
Adula californiensis, which inhabits mudstone along the open
coast and in Yaquina Bay, Oregon, is subjected to extremely varying
conditions. Laboratory experiments of a factorial design were used
to investigate the effects of temperature and salinity on survival,
growth and respiration during early development.
The rate of development to the...
The primary purpose of this study was to replicate a study of
Abel and Sahinkaya which investigated the emergence of race and sex
preferences of upper middle socioeconomic status Caucasian
children. This study provided a good match with respect to socioeconomic
status, race, and sex; however, the number of subjects...
The Peck Mountain area is located in west-central Idaho just 15 miles east of the Oregon-Idaho border. It is tectonically located within the "Columbia Arc" of the Nevadan oroaenic belt. The Seven Devils Volcanics, Permian to Traissic in age, are the oldest rocks in the area. They are composed of...
During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal
distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...
The metabolism of ¹⁴C-labeled ethyl -N, N-di-n- propylthiolcarbamate
(EPTC- ¹⁴C) was studied in adult female rats. Single
oral doses of EPTC-¹⁴C ranging from 0. 6 to 100. 6 mg were given
and the elimination pattern of ¹⁴C was determined.
Results of 18 experiments showed that increasing the doses
of EPTC-...
The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile)
to control broadleaf weeds in cereal crops has become widespread.
This herbicide has not always performed satisfactorily for reasons
which were not clearly evident.
The effects of temperature, light and humidity on the herbicidal
activity of bromoxynil on coast fiddleneck, Amsinckia intermedia,
were studied. Fiddleneck...
Twelve chemicals (Busan 72, Chloropicrin, Dacthal, Dexon,
Duter, EP 161, Lanstan, Methyl bromide, Phaltan, Vapam, Vidden D,
Vorlex) were tested to determine their effect on populations of certain
important soil-borne microorganisms including the onion pink root
fungus Pyrenochaeta terrestris. The soil used was from a field in
Malheur County, Oregon...
Several studies were conducted to determine if a more consistent
predictor of phytotoxicity to winter oats could be obtained with a
surfactant-herbicide ratio or a per-unit-volume concentration of surfactant,
independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium
(paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with
the nonionic surfactant X-77...
Pea streak virus (Marmor trifolii Holmes) is widespread and
occasionally destructive in Eastern Oregon and Washington, and in
many other pea growing areas. Since control by the use of insecticides
to kill the insect vector is only partially successful, resistant
varieties of peas are needed.
In a study to confirm...
Trypticase-Soy Broth (TSB) was inoculated with Streptococcus
diacetilactis, incubated at 21C for 24 hours and centrifuged to remove
the cells. When the spent TSB was inoculated with Staphylococcus
aureus, it allowed 99.8% less growth than fresh TSB. If the spent
TSB were supplemented with 0.08 μg/ml of niacinamide, this inhibition...
The inter-relationship of salmonberry and Douglas-fir on cutover areas was investigated in the Coast Range of western Oregon. Animal influences affecting the survival of Douglas-fir in a salmonberry
habitat were also investigated. The autecology of salmonberry was considered first by formulating a mathematical model to characterize the lateral encroachment of...
This thesis investigated on the dehalogenation of 2, 4-
dichloropyrimidine in various different conditions. These conditions
were changed by varying the solvents, the amount of catalysts and
the hydrogen chloride acceptors in order to study the effects on the
yields.
It was found that the ether-aqueous sodium hydroxide medium
with...
