Skew Brownian motion and branching processes applied to diffusion-advection in heterogenous media and fluid flow

Creator:: Ramirez, Jorge M.
Abstract:: This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics. In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...

Geochemistry of back arc basin volcanism in Bransfield Strait, Antarctica: Subducted contributions and along-axis variations

Creator:: Keller, Randall A., Fisk, Martin R., Smellie, John L., Strelin, Jorge A., and Lawver, Lawrence A.
Abstract:: Bransfield Strait is a Quaternary, ensialic back arc basin at the transition from rifting to spreading. Fresh volcanic rocks occur on numerous submarine features distributed along the rift axis, including a discontinuous neovolcanic ridge similar to the nascent spreading centers seen in some other back arc basins. Smaller edifices near...

Dynamical analysis of the upwelling circulation off central Chile

Creator:: Mesias, Jorge M., Matano, Ricardo P., and Strub, P. Ted
Abstract:: In this article we analyze the momentum and vorticity balances of a numerical simulation of the upwelling circulation off central Chile (34° –40°S) and its response to interannual local wind changes. Our analysis indicates that the path of the upwelling jet is strongly controlled by the bottom topography. This topographic...

A Socio-Economic Toolbox of Artificial Reef Projects

Creator:: Ramos, Jorge, Santos, Miguel N., Whitmarsh, David, and Monteiro, Carlos C.
Abstract:: It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...

A comparison of daily water use estimates derived from constant-heat sap-flow probe values and gravimetric measurements in pot-grown saplings.

Creator:: McCulloh, Katherine A., Winter, Klaus, Meinzer, Frederick C., Garcia, Milton, Aranda, Jorge, and Lachenbruch, Barbara
Abstract:: Use of Granier-style heat dissipation sensors to measure sap flow is common in plant physiology, ecology and hydrology. There has been concern that any change to the original Granier design invalidates the empirical relationship between sap flux density and the temperature difference between the probes. Here, we compared daily water...

Fish and amphibian use of intermittent streams within the upper Willamette Basin, Oregon

Creator:: Colvin, Randall William
Abstract:: In the fall through spring of 2002/03 and 2003/04, the composition of fish and amphibian communities were examined in intermittent streams in the upper Willamette river basin in western Oregon. I recorded standard aquatic habitat variables and water nutrient concentrations (nitrate and phosphate) and correlated them with fish and amphibian...

The effects of relaxation techniques on the quality of experience in people with dementia

Creator:: Chamberlin, Bethany
Abstract:: The purpose of this study was to test the effects of guided imagery on cognition, depression, anxiety, quality of life, behavior symptoms, and perceptions of self and others in people with dementia. A nonequivalent control group quasi-experimental design was used to compare an attention control group to the intervention group....

Characterization by optical methods of the heat denaturation of bovine serum albumin (BSA) as affected by protein concentration, pH, ionic strength and sugar concentration

Creator:: Kongraksawech, Teepakorn
Abstract:: The thermal denaturation of proteins has been extensively studied using several methods including differential scanning calorimetry (DSC). A custom-built optical system was used to study thermal effects on protein as an alternative method to DSC measurements. It was used to investigate the thermal stability of bovine serum albumin (BSA) with...

Primary production dynamics in the North Pacific subtropical gyre

Creator:: Corno, Guido
Abstract:: The North Pacific subtropical gyre (NPSG), once considered to be a biological desert due to low primary production (PP) and its associated variability, has been found more productive and variable than previously thought. The environmental conditions controlling this relatively high PP variability are yet to be elucidated, despite important implications...

A numerical study of the Southwestern Atlantic Sheld circulation : barotropic response to tidal and wind forcing

Creator:: Palma, Elbio D., Matano, Ricardo P., and Piola, Alberto R.
Abstract:: This article analyzes the barotropic circulation in the Southwestern Atlantic Shelf using a three-dimensional numerical model forced with winds and tides. South of 40°S, the shelf circulation is dominated by the propagation of the semidiurnal tides. In this region the diurnal tides are generally weak, except at the shelf edge...
