Species associations of fifteen major commercial groundfish species in the
northeastern Pacific ocean and their spatial and temporal characteristics were studied
using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used
to remove questionable data from the original logbook files, which resulted in the
exclusion of information...
Recently, there has been concern over the decline of the Pacific lamprey, Lampetra tridentata, in the northwestern United States. However, effective management has been impeded by data gaps in basic biology, especially in the early life stages. Consequently, in 2004 and 2005 I examined reproductive ecology, larval recruitment, and lamprey...
This thesis describes evaluation of a novel self-sealing chewable sustained release tablet that can maintain controlled release of drug regardless of compaction, crushing, or chewing. The new formulation contains polyethylene oxide which produces a sealant effect for cracks produced in the polymer coating during compaction. Dissolution studies were conducted and...
Students who believe that their intelligence is able to grow over time (malleable/ growth mindset) perform better on measures of academic success than students who believe that intelligence is a fixed trait that cannot be changed (fixed mindset; Dweck, 2000). Previous research on the effectiveness of mindset interventions have demonstrated...
Recent declines in nesting success of some fish-eating seabirds in Alaska have been attributed to declines in availability of certain schooling forage fishes (e.g., capelin Mallotus villosus, Pacific sand lance Ammodytes hexapterus, and Pacific herring Clupea harengus pallasi). These fishes tend to have high lipid content compared with other species...
As a major wheat exporter to countries all over the world, the United States has to
produce wheat that satisfy different quality requirements requested by their customers.
Over the past decade the United States has encountered a major problem, that of losing
market share in Asia to Canada and Australia....
'Marion' blackberry is known for having excellent aroma and flavor, yet they are susceptible to damage by freezing and they are very thorny. Thornless blackberry cultivars have been developed and show great potential. Thus, the interest of the study was in determining which of eight thornless blackberry cultivars, have similar...
A focus group interview consisting of 25 international Taiwanese students and a consumer survey in which 793 native Taiwanese urbanites participated were conducted. Both studies investigated the purchasing and consumption behaviors, attitudes, opinions and expectations of Taiwanese people toward cheese. The focus group results provided good predictions and explanations of...
In order to properly utilize organic amendments as nitrogen sources, reliable methods
to estimate plant-available nitrogen (PAN) are needed. The objectives of this study
were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence
(FNE) calculations, (2) examine the relationships between the C/N ratio, total...
The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...
