The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
Nisin, bacteriocin produced by Lactococcus lactis, Nisin may have the potential to replace (or reduce) sulfiting agents traditionally added to wines to prevent the growth of spoilage lactic acid bacteria. This may be valuable since sulfites are believed to cause toxic responses in sensitive individuals. As a result, the U.S....
Riesling, Chardonnay, and Pinot noir wines from the 1992 vintage were fermented with several different commercial yeast strains. Differences were observed in fermentation rates, wine composition, and aroma and flavor. Preliminary results were reported on in the OSU Wine Grape Research Progress Reports, 1992-1993, Special Report 929, June 1993, OSU...
Oregon Pinot noir wines differ greatly in their color and phenolic profiles and this variability is due to both vineyard and to fermentation management practices. We have observed that Pinot noir fruit composition can vary significantly with vintage, with degree of maturity, with yields, with trellis systems, and with the...
In experiments in grape skin light transmission in 1991, we found that quercetin (a phenolic compound found in many plants) accumulates in sun exposed grape skin. The accumulation of quercetin in grape skins appeared to be a protective response to solar radiation and we were able to show that quercetin...
The new varietal trial at SOES was monitored during the growing season and during ripening by David Sugar and Porter Lombard (see Winegrape Variety Trial in Southern Oregon). The 1993 vintage was a late ripening season and not all the varieties developed sufficient maturity for experimental wine production. Tempranillo, Viognier,...
Minimal pruning continues to look like a production system worthy of consideration in small scale commercial trials. In 1993, in a trial on Chardonnay at Woodhall vineyard, minimal pruning was compared to standard cane pruned vines on a vertical trellis. This was the second year of the trial.
The easiest way to introduce phylloxera to a site is by infested plant material. If a grower can effectively remove any existing phylloxera on new plants, the rate of spread of phylloxera. in Oregon vineyards will be significantly decreased.
The objectives of this study are to determine methods for dipping...
We have measured voltage-current characteristics for YBa₂Cu₃O₇ thin films in magnetic fields from 5
T to ambient, including some in the millitesla range. In all cases, the resistivity —current density isotherms
can be separated into two classes: those which exhibit upward curvature, and have constant
resistivity at low currents, and...
"This workshop was held to allow both research and management fish biologists to openly discuss the results of several ongoing projects designed to improve the way Oregon manages its steelhead populations." (from the Introduction) The report uses an extended abstract format.
The divergence theorem as usually stated cannot be applied across a change of signature unless it is reexpressed to allow for a finite source term on the signature change surface. Consequently all conservation laws must also be ‘‘modified,’’ and therefore insistence on conservation of matter across such a surface cannot...
The divergence theorem in its usual form applies only to suitably smooth vector fields. For vector fields which are merely piecewise smooth, as is natural at a boundary between regions with different physical properties, one must patch together the divergence theorem applied separately in each region. We give an elegant...
Excessive growth by red clover, Trifolium pratense L., grown for seed
interferes with maximum seed production and harvest in Oregon's Willamette Valley.
This study was conducted during 1986 and 1987 on red clover cv. Kenland to
determine if plant height and dry matter production could be inhibited and seed yields...
In a conventional well-mixed fluidized bed the solids are almost
completely mixed and the residence time for individual particles may vary
between zero and infinity. For materials especially sensitive to the processing
time, a wide distribution of residence time is extremely undesirable. A multi-compartment
fluidized bed was proposed to minimize...
The study of the social dimensions of Shakespeare's art is represented by the work of Mikhail Bakhtin, C.L. Barber, Robert Weimann, Edward Berry, and Michael Bristol. Their work analyzes the background in Elizabethan social practices and popular dramatic traditions that contribute to the form, structure, and meaning of Shakespeare's comedies....
The Asian noodle market is responsible for the increased volume of wheat
imported to that region in recent years. Soft white wheat produced in the Pacific
Northwest is mainly used for baked products, whereas an Australian wheat,
Australian Standard White, is preferred for noodles. To enter this market soft
white-wheat...
The study presents the results of a descriptive analysis of the skeletal remains of 66
individuals recovered from the Fuller and Fanning Mound sites, located on the Yamhill River,
Willamette Valley, Oregon, excavated in 1941-42 by W. T. Edmundson and William S.
Laughlin. The literature and original field notes have...
This thesis describes the analysis and comparison of Folded Source-Coupled
Logic (FSCL) with standard static CMOS, cascode voltage-switch logic and differential
split-level logic gates. The advantages of FSCL are low switching noise and
high operating speed. The effect of voltage and device scaling on these topologies is
evaluated in terms...
A mathematical model of Limiting Dilution Analysis for two limiting
parameters is presented and investigated. Limiting Dilution Analysis is a microbiological
cell assay developed for immunological application. In the given
case we deal with the interaction between B lymphocytes, macrophage derived
factor and T-independent antigens. The state of the art...
This study evaluates the effect of an Acquired Immune Deficiency Syndrome (AIDS) prevention program on the incidence of gonorrhea among the enlisted men in the 105th Battalion of the Honduran Army. The education program was initiated as a result of the high incidence of AIDS in Honduras (more than half...
Nine west-northwest-trending faults on the continental margin of
Oregon and Washington, between 43° 05'N and 470 20'N latitude, have been
mapped using seismic reflection, sidescan sonar, submersibles, and swath
bathymetry. Five of these oblique faults are found on both the Juan de Fuca
and North American plates, and offset abyssal...
Zora Neale Hurston was a Black American writer
during the period of the Harlem Renaissance. The
purpose of this study is to show that three of her four
novels form a protracted discussion of a particular
type of freedom which was of especial interest to
Hurston. The study seeks to...
Abraham Heschel wrote that a philosopher's primary task was not merely to describe and judge the modes and facts of actual human behavior, but also to examine and understand the meaninq of those descriptions and judgements of modes and facts (Bella, 1978). Our values are critically tied to our structures...
Interspecific predation and cannibalism and associated rates of oviposition were
assessed for adult female Metaseiulus occidentalis (Nesbitt) and Typhlodromus pyri
Scheuten when provided non-limiting amounts of either eggs, larvae, protonymphs, or
deutonymphs. Tests with all four stages of phytoseiids and larvae of Tetranychus urticae
Koch were carried out at 25°C....
Six experiments were carried out with Single Comb White Leghorn laying chickens to
assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its
carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and
several minerals; on the status of the pH of the...
A synthetic approach toward the two major fragments of cathedulin K-19,
euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of
dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed
towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran
sesquiterpene, was advanced to a stage in which...
Bidirectional reflectance is a fundamental property
used for the analysis of radiative heat transfer. It is a
form of reflectivity in which the spectral and directional
dependencies of both the beam incident on a surface and the
beam reflected from the surface are specified.
A new system has been designed...
Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
This paper provides logit estimates of the probability that students will
cheat in a specific class using randomized response and direct question data in
two logit models. The results predict that there are several indicators of the
probability of cheating occurring in a class. These factors include both student
and...
The solution of coupled neutronic/thermal hydraulic nuclear reactor calculations
requires the treatment of the nonlinear feedback induced by the thermal hydraulic
dependence of the neutron cross sections. As a result of these nonlinearities, current
solution techniques often diverge during the iteration process. These instabilities arise
due to the low level...
More than 30,000 potential Superfund sites have been identified. Heavy metals are contaminants at many of these Superfund sites. The average cost of cleanup a single-typical Superfund site currently stands at $20 million, and it is expected that the cost may escalate to $50 million within the next decade. Problems...
