Summer surface waters in the Gulf of California: Prime habitat for biological N₂ fixation

Creator:: White, Angelicque E., Prahl, Fredrick G., Letelier, Ricardo M., and Popp, Brian N.
Abstract:: We report significant rates of dinitrogen (N₂) fixation in the central basins of the Gulf of California (GC) during July–August 2005. Mixing model estimates based upon δ¹⁵N values of particulate matter in the surface mixed layer indicate that N₂ fixation provides as much as 35% to 48% of the phytoplankton-based...

Seasonal patterns of alkenone production in the subtropical oligotrophic North Pacific

Creator:: Popp, Brian N., Prahl, Fredrick, Wallsgrove, Richard J., and Tanimoto, Jamie
Abstract:: Seasonal alkenone concentrations, production rates, and unsaturation patterns (U₃₇ᴷ') were measured at station ALOHA in the oligotrophic subtropical North Pacific. Highest alkenone concentration and production rates were found in (winter and fall) or just below (summer) the surface mixed layer. Lowest alkenone concentration and production rates were found within the...

A new method for estimating growth rates of alkenone-producing haptophytes

Creator:: Popp, Brian N., Bidigare, Robert R., Deschenes, Bryan, Laws, Edward A., Prahl, Fredrick, Tanimoto, Jamie K., and Wallsgrove, Richard J.
Abstract:: Laboratory culture experiments were performed to establish the range of growth conditions where ¹³C labeling of di- and tri-unsaturated C₃₇ methyl ketones yields reliable growth rates for alkenone-producing algae. Results document that even at low growth rates and short time intervals, ¹³C labeling of the di-unsaturated C₃₇ alkenone provides reasonable...

Nitrogen fixation in the Gulf of California and the Eastern Tropical North Pacific

Creator:: White, Angelicque E., Foster, Rachel A., Benitez-Nelson, Claudia R., Masqué, Pere, Verdeny, Elisabet, Popp, Brian N., Arthur, Karen E., and Prahl, Fredrick G.
Abstract:: Di-nitrogen (N₂) fixation plays a well-recognized role in the enhancement of primary production and arguably particle export in oligotrophic regions of the subtropical and tropical oceans. However, recent evidence suggests that N₂ fixation may also be significant in regions of the surface ocean proximate to or overlying zones of intense...

A study of opposing mixed convection in the GRTS and in downward pipe flows using the FLUENT CFD code

Creator:: Jackson, R. Brian
Abstract:: Downward flow opposing mixed convection conditions have been studied using the FLUENT CFD code. This work was comprised of two primary objectives. The first was to study core channel flow reversal susceptibility in the Gas Reactor Test Section (GRTS) at low flow conditions. The second objective was the development of...

Nonlocal electromagnetic theory of fluids with applications to surface waves in a dielectric fluid

Creator:: McCay, Brian M.
Abstract:: The last two decades have seen many new continuum models for electromagnetic materials which were constructed by merely adding terms to the classical balance laws and constitutive equations. Nonlocal theories, such as the one developed by A. C. Eringen., however, depart from the traditional approaches by accounting for the effects...

Development and experimental validation of a discrete particle simulation for fluidized beds with external and inter-particle forces

Creator:: Reed, Brian Patrick
Abstract:: Traditional modeling of fluidized bed operations has focused on the development of models and correlations for specific systems or narrow areas of application. With recent advances in computing power, new methods of modeling fluidization are possible. One such approach is the Computational Fluid Dynamic Discrete Particle Method (CFD-DPM), which treats...

Evaluation of a Monoclonal Antibody for Studying MHC Class I Antigen Presentation In-Vitro

Creator:: VanderHoek, Eden N.
Abstract:: Human epidermal growth factor receptor 2 (HER2), a member of the receptor tyrosine kinase (RTK) family, is frequently dysregulated in a variety of cancers. Overexpression of the receptor leads to increased cell proliferation and resistance to cell death due to downstream signaling effects. Proteasomal degradation of HER2 results in the...

Lipid Metabolism and the Broiler Chicken : Effect of Dietary n-3 Fatty Acids

Creator:: Head, Brian A.
Abstract:: In broiler chickens, hepatic lipid metabolism plays a significant role in whole body and muscle fatty acid (FA) incorporation. Flax seed is a rich source of α-linolenic acid and can be used to increase n-3 FA in poultry meat. Previous studies have shown that flax seed in combination with carbohydrase...
