Subseasonal variability in a two-level atmospheric general circulation model

Creator:: Kushnir, Yochanan
Abstract:: The dynamical processes which maintain atmospheric disturbances in regions of strong wintertime variability of the northern hemisphere are examined using data from a GCM simulation. Time series of the dependent variables and diabatic heating components from 10 Northern Hemisphere winters simulated by the Oregon State University two-level GCM are used....

Xenobiotic biotransformation in aquatic organisms

Creator:: Schlenk, Daniel K.
Abstract:: Aquatic animals are exposed to a variety of natural and anthropogenic xenobiotics. Biotransformation of xenobiotics was examined in three aquatic animals: a primitive mollusc (chiton); a shellfish which is an important human food source (oyster); and, a lower vertebrate model for toxicological studies (rainbow trout). Since digestive glands of Cryntochiton...

A numerical study of coastal stratus cloud in a two-dimensional meso-scale model

Creator:: Lee, Tae Young
Abstract:: A two-dimensional numerical mesoscale model, which ic1udes radiative and turbulent transfers, has been constructed to study the formation, development and dissipation of coastal stratus cloud under an inversion. In the model, the delta-Eddington and emissivity approximations are used for the solar and thermal radiative transfers, respectively. K-theory parameterization is adopted...

Inhibition of Escherichia coli trimethylamine-N-oxide reductase by food preservatives

Creator:: Kruk, Mark W.
Abstract:: Trimethylamine-N-oxide (TMA-0) reductase activity of resting cells of Escherichia coli was inhibited by tetrasodium ethylenediaminetetraacetate (Na₄EDTA), benzoic acid (BA), and methylparaben (MP). The 50% inhibitory concentrations of Na₄EDTA, BA, and MP were 20.2, 1.2, and 32.4 mM, respectively. BA at pH 6.5 or below most effectively inhibited the TMA-0 reductase....

Biaxial fatigue behavior of commercially pure titanium Ti-50A (Grade 2) and low-alloy titanium Ti-Code 12 (Grade 12) heat exchanger materials

Creator:: Tobias, Benjamin C.
Abstract:: Material failures in heat exchangers are often closely tied to events associated with the conditions of service and operating parameters. These events can generally be attributed to adverse load application and higher than optimum operating temperatures that could lead to changes in the microstructure of the materials and fatigue failure...

Human health significance of vibrios from the aquatic environment

Creator:: Nishibuchi, Mitsuaki
Abstract:: For the enrichment and enumeration of Vibrio fluvialis, a broth medium was designed by modifying alkaline peptone (AP) medium. This new V. fluvialis enrichment medium (FEM) was shown to be more effective than AP medium in field samplings where a total of 177 samples (estuarine waters and sediment, sewage, and...

Microbiological control of food spoilage and pathogenic microorganisms in refrigerated foods

Creator:: Al-Zoreky, Nageb
Abstract:: Microgard, a commercially-available pasteurized fermented milk, was found inhibitory to gram negative bacteria such as Pseudomonas putida, some well-known foodborne pathogens (e.g. Salmonella, Yersinia and Aeromonas) and some fungi as revealed by an agar incorporation assay method. Gram positive bacteria, however, were not inhibited. Rather, some bacteria in this group...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...
