Modeling Eddy Correlation Biases Created by Velocity Sensitivities of Clark-type Oxygen Microelectrodes Under Waves

Creator:: Albright, Andrea and Albright, Andrea T. P.
Abstract:: Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...

Age, growth, and long-distance dispersal in the western North Atlantic of vexillifer larvae of the pearlfish, Echiodon dawsoni, with notes on Carapus bermudensis (Ophidiiformes: Carapidae)

Creator:: Govoni, John J., Terwilliger, Mark, and Markle, Douglas F.
Abstract:: We examined 120 vexillifer larvae of Echiodon dawsoni and 40 of Carapus bermudensis collected from the continental shelf and slope of the Gulf of Mexico and the western North Atlantic to Nova Scotia. Age was estimated for a subset of vexillifers, from which otoliths (sagittae) were excised and growth increments...

The extraction of pentachlorophenol from pressure treated wood using supercritical carbon dioxide

Creator:: Yi, Jung-Seok
Abstract:: The extraction of pentachlorophenol (PCP) from pressure treated wood wafers with supercritical carbon dioxide has been studied. Experimental data were obtained for the effects of pressure (17.5 - 25.0 MPa), temperature (313 - 353 K), flow rate (1 - 3 ml/min at supercritical conditions), and sample size (0.8 x 10...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Geostatistical applications to salinity mapping and simulated reclamation

Creator:: Al-Taher, Mohamad A.
Abstract:: Geostatistical methods were used to find efficient and accurate means for salinity assessment using regionalized random variables and limited sampling. The random variables selected, sodium absorption ratio (SAR), electrical conductivity (EC), and clay content were measured on samples taken over an area of fifteen square miles. Ordinary kriging and co-kriging...

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...

Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

Cyclic nucleotides, cyclic nucleotide phosphodiesterase, protein kinase, and phosphoprotein phosphatase in the central nervous system of Manduca sexta

Creator:: Albin, Edward Elmo
Abstract:: Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...

S-adenosylmethionine : [triangle]²⁴-sterol methyltransferase and the regulation of ergosterol biosynthesis in Saccharomyces cerevisiae

Creator:: Bailey, Richard B.
Abstract:: The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase (EC 2.1.1.41) activity by endogenous cellular components has been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺, NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition by potassium cation has been studied, and we have found that energy...
