In this study, we use a time domain numerical model based on the fully nonlinear extended Boussinesq equations [Wei et al., 1995] to investigate surface wave transformation and breaking-induced nearshore circulation. The energy dissipation due to wave breaking is modeled by introducing an eddy viscosity term into the momentum equations,...
The Mx protein family of rainbow trout (Oncorhynchus mykiss) was characterized at the molecular level. With primers derived from a partial sequence of Perch (Perca fluviatis) Mx genomic DNA, a partial rainbow trout Mx genomic DNA sequence was obtained by polymerase chain reaction (PCR) amplification. All salmonid fish investigated contained...
Recent advances in DNA vaccine technology has brought about a promising strategy for the control of viruses that contain surface membrane glycoproteins. This type of vaccine involves the intramuscular injection of a bacterial plasmid containing a gene encoding a viral protein. The strategy uses eukaryotic processing of the protein as...
Hatchery-reared salmonid fish routinely encounter stress due to
handling, barging, tagging, and overcrowding. It has been demonstrated that
there exists a direct correlation between stress and transient immune
suppression which can last for many days in fish. Epizootic viral infections
routinely appear in hatcheries and can have a devastating effect...
The influence of overstory openness on the reproductive
ecology of Pacific yew (Taxus brevifolia Nutt.) was
investigated on 4 sites in western Oregon over 2 years. The
breeding system of T. brevifolia was found to deviate from
pure dioecy under a broad range of canopy and site
conditions. Production of...
2 μm average sized silicon powder was nitrided with 90% N₂/10% H₂ in a
fluidized-bed reactor, operated at 1200°C, 1250°C and 1300°C. To fluidize silicon
powder, alumina particles with an average size of 300 μm were used as an inert fluidizing
conditioner. The feasibility and operating conditions of the fluidization...
Flavin-containing monooxygenase (FMO, EC1.14.13.8) comprises a family of
xenobiotic-metabolizing enzymes that catalyze the oxygenation of a wide variety of
xenobiotics, most commonly nitrogen and sulfur. Mammals express five different FMOs
in a species- and tissue- specific manner. FMO2, is expressed predominantly in lung and
differs from other FMOs in that...
This thesis examines the interconnection between the in vitro and in
vivo phosphorylation of rabbit muscle phosphofructokinase. The first goal
of the project was to show whether a novel site of rabbit muscle
phosphofructokinase that is subject to in vitro phosphorylation, serine 376,
may also become phosphorylated in vivo. Evidence...
Rapid degradation of certain short lived "timing" proteins is
an effective mechanism for cells to control important regulatory
pathways. The mechanisms by which regulatory proteases
recognize their substrates are not well understood. Escherichia coli
Lon, an energy dependent protease highly conserved in many
prokaryotes and eukaryotes provides a model system...
