Influence of stratification and accelerations on boundary production of vertical motion

Creator:: Park, Soon-Ung
Abstract:: The influence of boundary layer pumping on an externally-forced synoptic-scale flow is examined. The results follow earlier theories of stratified incompressible Boussinesq flow. These theories state that the spin-down time scale and the penetration depth of the influence of boundary layer pumping are inversely proportional to the stratification and directly...

Nonlinear free boundary problems arising from melting processes

Creator:: Park, Tae-soon
Abstract:: We discuss a mathematical model arising in the melting of a fluid in two spatial dimensions and in time. The model leads to a free boundary value problem for determining the location of the interface as well as the temperature distribution. The movement of the interface depends on the temperatures,...

Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

Effects of physiological state upon nitrosoguanidine-mediated allelic recombination in Saccharomyces cerevisiae

Creator:: Buettner, Michael John
Abstract:: Saccharomyces cerevisiae strain XS-380, a. heteroallelic diploid strain, carries six genetically analyzed loci on the left arm of chromosome VII. Nitrosoguanidine (NMG) at low concentrations was observed to cause allelic recombination (either mitotic recombination or gene conversion) of the heteroallelic loci with low lethality. The NMG-inducible heteroallelic system was used...

Control of macromolecular synthesis in Saccharomyces cerevisiae

Creator:: Wehr, Carl Timothy
Abstract:: Synthesis of total RNA, DNA, and protein was followed in a haploid yeast auxotroph during starvation for required amino acids and uracil, and during shift-up and shift-down conditions. During amino acid starvation, synthesis of macromolecular constituents was not immediately affected, reflecting the presence of large intracellular amino acid pools. Under...

Regulation of the terminal reactions for methionine biosynthesis in yeast

Creator:: Spence, Kemet Dean
Abstract:: Studies were carried out to elucidate the mechanism of enzymatic control of methionine biosynthesis in Saccharomyces cerevisiae. Enzymatic studies demonstrated that, in addition to the methionine activating enzyme, the S-adenosylmethionine:homocysteine transmethylase enzyme was induced during cultivation in the presence of excess methionine. A similar, though reduced effect was observed when...

Defining roles for sterols in Saccharomyces cerevisiae : characterization of bulk membrane and high specificity sparking functions

Creator:: Rodriguez, Russell John
Abstract:: The ability of cholestanol to support growth of yeast sterol auxotrophs has been examined. Growth on this stanol was precluded unless minute quantities of ergosterol were available, a phenomenon designated sparking. The low levels of ergosterol were insufficient to support growth alone. The data indicate that cholestanol is fulfilling a...

Biochemical and Physical Characterization of Fish Protein Isolate and Surimi for their Compatibility

Creator:: Kobayashi, Yuka
Abstract:: There are presently two successful methods used to refine fish muscle proteins: surimi and fish protein isolate (FPI). Both surimi and FPI have the ability to form an elastic gel upon comminution and heating. However, their gelation behaviors are different as they are refined in a biochemically opposite way based...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...
