Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...
Fermentation of the grape must into wine is one of the most important steps in winemaking. Selected yeast strains of Saccharomyces cerevisiae have been used for many years to ensure complete and even fermentations. The formation of volatile compounds also occurs during fermentation and will influence the sensory perception of...
Wines were made from Pinot Noir and White Riesling grapes
which had received field application rates of 2 and 4 lb./acre of the
experimental bird repellent Mesurol (methiocarb or 3, 5 dimethyl-
4(methylthio)phenylmethylcarbamate). In addition, Pinot Noir must
and press juice and White Riesling press juice were fortified with
15...
Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...
Studies towards the total synthesis of (−)-kendomycin (1), a bacterial metabolite with
a unique molecular architecture and pronounced biological activity, are described. These
studies resulted in the synthesis of advanced intermediate 208, containing all of the
carbon atoms of 1.
A Dötz annulation between alkyne 122 and novel chromium carbenoid...
There is an increasing need for development of laboratory
identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field
testing methods based on morphological differences were used satisfactorily. These tests require several months to complete...
The kraft and kraft-anthraquinone pulping processes were used
for pulping Douglas-fir chips at 170°C, 180°C and 190°C temperatures.
Anthraquinone was added to the pulping liquor at two levels, 0.1%
and 0.2% based on wood, to study its effect on pulp delignification
at the three temperatures. The fluorescent behaviors of kraft...
My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...
The COVID-19 pandemic impacted the international development sector through various external and internal stressors. Community engagement practices that international non-governmental organizations and non-profits conducted were disrupted by the pandemic, and communities were faced additional challenges when international development workers were required to socially distance or relocate at the onset of...
This study sought to understand the unique challenges that housing insecurity programs faced during the COVID-19 pandemic. An anonymous Qualtrics survey, containing closed- and open-ended questions, was sent to housing insecurity programs in Benton County, Oregon. Questions focused on how the COVID-19 pandemic affected services and how programs adjusted to...
Listed as endangered in 1988, the Lost River sucker (Deltistes luxatus) and Shortnose sucker (Chasmistes brevirostris) were once abundant and widely distributed in the Klamath Basin in Southern Oregon and Northern California. Populations of both species have been declining since the late 1960’s. Factors thought responsible for declines include naturally...
Antagonistic effects of Epicoccum purpurascens,
Aureobasidium pullulans, Trichoderma spp., and Botrytis
cinerea on establishment of Monilinia fructicola infections
in cherry and peach blossoms were assessed in field and mist
chamber studies. Conidia of each fungus were applied to
blossoms that were subsequently inoculated with conidia of
M fructicola. Mist chamber...
Ragay Gulf and Burias Pass are among the traditional fishing grounds of the
country being considered by the government for an integrated approach to fishery
management (Smith, et al., 1980; Samson, et al., 1977, World Bank, 1976). The
Department of Marine Fisheries, College of Fisheries, University of the Philippines in...
Attempts to map the distribution of acidic
deposition have been inadequate, particularly in areas of
seasonal or limited rainfall. Ambient air concentrations
of acid precursors may be used to monitor and map the
distribution of potential acidic deposition. A network of
stations in California currently monitor these ambient air
concentrations....
Gynoecious inbred lines of cucumbers (Cucumis sativus
L.) with high (HF), medium (MF) and low (LF) percentage of
gynoecious plants were used in crosses with monoecious
Chinese cultivars with high (HN), medium (MN) and low (LN)
percentage of nodes with female flowers. F₁ and F₂ progenies
from these parents crossed...
The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄.
solutions on the mineral content, growth, yield and fruit quality of
sweet cherry and mineral content of prune were investigated. A
complimentary study presented in Appendix 1, was conducted to
evaluate the short term effectiveness of K soil amendments, mulching...
