Characterization of organic matter quality and content in Columbia River suspended particulate matter by cupric oxide oxidation

Creator:: Alleau, Yvan M.
Abstract:: The organic content of the Columbia River suspended particulate matter (SPM) results from the input of autochthonous (phytoplankton) and allochthonous (terrestrial vascular plants) production. The contribution of these two sources appears seasonal and responds to factors such as rainfall, runoff, river flow, light and nutrients availability. While numerous studies have...

Substrate degradation kinetics, microbial diversity, and current efficiency of microbial fuel cells supplied with marine plankton

Creator:: Reimers, Clare E., Stecher, Hilmar A., Westall, John C., Alleau, Yvan, Howell, Kate A., Soule, Leslie, White, Helen K., and Girguis, Peter R.
Abstract:: The decomposition of marine plankton in two-chamber, seawater-filled microbial fuel cells (MFCs) has been investigated and related to resulting chemical changes, electrode potentials, current efficiencies, and microbial diversity. Six experiments were run at various discharge potentials, and a seventh served as an open-circuit control. The plankton consisted of a mixture...

Th-234 applied to particle removal rates from the surface ocean: A mathematical treatment revisited

Creator:: Alleau, Y., Colbert, D., Covert, P., Haley, Brian A., Qiu, X., Collier, Robert W., Falkner, Kelly, Hales, Burke, Prahl, Fredrick, and Gordon, L.
Abstract:: It has been recognized since the 1950's that radioisotopic disequilibrium between naturally occurring parent-daughter isotope pairs in seawater can provide information on the rate of processes segregating them. In the surface ocean, the U-238:Th-234 parent-daughter pair tends to display measurable disequilibrium that is attributable to the effects of scavenging on...

Powersim : a tool for energy consumption estimation of Palm Pilot applications

Creator:: Lazard, Laurent
Abstract:: In this thesis, we develop a simulator for estimating the energy consumed in executing tasks on a mobile device - the Palm Pilot. We measured the energy consumed by each instruction of the device's assembly language and incorporated these measurements into a public domain emulator for the Palm Pilot. This...

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

Utilization of natural and supplemental biofuels for harvesting energy from marine sediments

Creator:: Nielsen, Mark E.
Abstract:: A benthic microbial fuel cell (BMFC) is an electrochemical device that generates current from the redox gradient at the sediment-water interface. Early prototypes had anodes buried in anoxic sediments and cathodes in overlying water. The BMFCs described in this dissertation are based on a chamber design that enables the use...

Micro-economic Efficiencies and Macro-economic Inefficiencies: Theoretical Reflections on Renewable Resource Policies in Very Poor Countries

Creator:: Wilson, James R. and Boncoeur, Jean
Abstract:: Economists in developed countries having specific institutional and macroeconomic conditions have been the major contributors to fisheries economics theory and policy. Whereas the theory and the policies may be appropriate in certain circumstances for developing countries, it is not necessarily true that the two major recommendations of fisheries theory, capacity...

An alternative architecture for performing basic computer arithmetical operations

Creator:: Djang, Kevin
Abstract:: The arithmetic portions of almost all modern processor architectures are of very similar design. We use the term "traditional" to describe this design, the primary characteristics of which are native support for integer and floating-point number types and special disjoint instructions and hardware for each supported type. Decades of refinement...

Towards a deep pluralism in an emerging polity : immigration and integration in France and the European Union

Creator:: Donahue, Cody N.
Abstract:: The issue of immigration is at the forefront of all national policy discussions in the industrialized world. In recent years, the globalization of communication, international travel and job opportunities has rekindled this historically long and complex debate. This text attempts to explore the inadequacies of immigration policy and practice in...
