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,...

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...

Nitrate reductase activity as a factor influencing the seasonal succession of marine phytoplankton

Creator:: Roelofs, Nancy Ann
Abstract:: Nitrate reductase is known to be the enzyme regulating the reduction of nitrate to nitrite in plants. This reduction is the first and rate-limiting step in the transformation of inorganic nitrate to a cellular nitrogen form. Since this reduction process is essential to phytoplankton growth when nitrate is the only...

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 factors affecting fish ball

Creator:: Kok, Tiong Ngei, 1974-
Abstract:: Fish ball is an extruded surimi-based product that is popular among Asian communities. In the manufacturing of fish ball, optimum floatation is extremely important for maximal production. Factors affecting floatation of fish ball in water were investigated. The density of threadfin bream surimi paste significantly decreased (P<O.05) as moisture content...
