During the course of ripening, Cheddar cheese frequently develops
a flavor defect described as fruity. Recent work has indicated
that the use of certain starter cultures ultimately results in the
development of the defect as the cheese ages. The flavor compounds
responsible for the defect, however, have not been elaborated....
The dynamics of N was studied in field grown Comice/Provence
quince BA29 pears in Medford, Oregon. Total tree biomass, N content,
and ¹⁵N evaluations suggest that young pears require little N (48 kg
N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was
remobilized into new...
Spore dispersal gradients and pod disease gradients from point
inoculum sources of Botrytis cinerea were measured over time in two
snap bean field experiments. Laboratory grown inoculum was placed
at ground level in a 30 x 30 cm square at bloom initiation and
removed at full bloom. Dispersal of inoculum,...
A study was conducted to determine the effects or
temperature, solar radiation, rainfall, and saturated flow
on fecal coliform numbers in sewage sludge-amended soils.
To determine this, four 4.6 X 13.7 m field plots were each
amended in summer and in winter with 800 liters of
anaerobically-digested sewage sludge, and...
Copper and zinc are heavy metals commonly present in highway stormwater runoff. Discharge of these metals to surface waters inhabited by sensitive aquatic species including threatened and endangered salmonids has necessitated the need for improved treatment techniques. Although copper is of the greater toxicological concern, zinc is often present at...
The general objective of this study is to analyze the production
and the consumption of food in Korea for the years 1955 through 1969
and to project them for the years 1970 through 1980. This study has
the following purposes;
(1) To examine the trend in food production and yield....
Reported here is an investigation to determine the in vitro and in vivo metabolism
of xanthohumol (XN). XN is the major prenylated flavonoid of the female
inflorescences (cones) of the hop plant (Humulus lupulus). It is also a constituent of
beer, the major dietary source of prenylated flavonoids. Recent studies...
This thesis details my investigation of some pharmaceuticals and natural products on the transport of drugs which are substrates of P-glycoprotein (P-gp), such as cyclosporin A (CSA) and digoxin by using Caco-2 and MDCKII-MDR1 drug transport models. Three objectives were performed to address this goal. The first objective was to...
This study was designed to confirm or refute the tenderizing
effect of ultra-hydrostatic pressure on warm excised pre-rigor
muscle, plus to take a thorough look at its effect on some meat
characteristics of economic importance.
Samples for the experiment were obtained from animals (cattle
and sheep) slaughtered at Oregon State...
Electrical stimulation of beef carcasses (n=18) did not cause a
significant reduction in microbial population on three different sampling
positions immediately following slaughter. In constrast, significant
microbial reduction (P > 0.05) was found at position 2 (muscle
above aitch bone), but not at position 1 (inside of neck) or position...
Little is known about the fall and winter ecology of hibernating bats in western North America. Filling knowledge gaps for these populations has become more urgent with the westward spread of the white-nose syndrome, a disease that infects bats during hibernation. Due to the thermal requirements of the fungal pathogen...
Successful cryopreservation of bone marrow in situ within vertebral bodies offers an opportunity for quick and convenient storage of a significant quantity of bone marrow stem cells, including hematopoietic- and mesenchymal-type stem cells. However, cryopreservation of more complex large tissues and organs, such as the vertebral body (VB), remains problematic....
On a global scale, potato (Solanum tuberosum L.) plays an important role in tackling the threat of food insecurity due to its high yield and broad global acceptance. However, pathogens threaten potato production, causing direct yield loss and rendering potatoes tubers unmarketable. Breeding new cultivars that carry multiple resistances is...
The spread of nonnative species across the globe has contributed to biodiversity loss and changes in ecosystem structure and function. Monitoring the introduction, naturalization, and spread of introduced species is critical in abating negative impacts wrought by species invasions. However, providing basic information concerning the presence or spread of many...
Young children with developmental disabilities (< 12 years old) participate less in physical activity (PA) and experience motor skill deficits compared to young children without disabilities (Jung, Leung, Schram, & Yun, 2018; Liu, Hamilton, Davis, & ElGarhy, 2014; Whyatt & Craig, 2012). When taking account of a bi-directional relationship between...
