In situ measurement of the benthal oxygen requirements of tidal flat deposits

Creator:: Crook, Gene Ray
Abstract:: In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

Spatial, diel and seasonal variations in dissolved oxygen and temperature within a stratified lake

Creator:: Smith, Stanley Allan
Abstract:: Spatial, diel and seasonal variations in dissolved oxygen and temperature were measured in Triangle Lake, Oregon. Spatial dissolved oxygen and temperature variations measured in the stratified lake are presented to illustrate the horizontal uniformity of the lake and to demonstrate the applicability of the one dimensional assumption for sampling and...

Incorporation of diet information derived from Bayesian stable isotope mixing models into mass-balanced marine ecosystem models : a case study from the Marennes-Oléron Estuary, France

Creator:: Pacella, Stephen Roger
Abstract:: This thesis presents two related studies on the methodology for creating, and subsequently analyzing, an inverse food web model of an intertidal seagrass bed. The first study (Chapter 2) describes, for the first time in the literature, a method for incorporating isotopic information gained from Bayesian mixing models into an...

Some effects of dissolved oxygen concentration on feeding, growth and bioenergetics of juvenile Coho salmon

Creator:: Thatcher, T. O.
Abstract:: The effects of three levels of dissolved oxygen (8, 5 and 3 mg/l) upon the feeding, growth and bioenergetics of juvenile coho salmon, Oncorhynchus kisutch (Walbaum), were determined in laboratory studies. Experiments with individual fish were conducted during the summer, fall and spring to measure rates of food consumption, standard...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...

Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

An experimental investigation of combustion products through a flat, laminar, pre-mixed hydrocarbon-air flame

Creator:: Brenchley, David Lee
Abstract:: Flat, laminar, premixed hydrocarbon-air flames were stabilized on a porous-plate burner. In addition to temperature profiles, concentration profiles were measured for methane, ethane, ethylene, propane, acetylene, propylene, carbon monoxide, carbon dioxide and oxides of nitrogen. Dead space thickness, luminous flame zone thickness and hydrocarbon disappearance point responses were also monitored....

Pectolytic enzyme production by Fusarium oxysporum f. sp. lycopersici

Creator:: Baldwin, Charles Harry
Abstract:: This investigation was undertaken to determine 1) the effects of various carbon sources in defined media on pectolytic enzyme production, 2) the effect of the incubation period on pectolytic enzyme activity, and 3) the development of improved methods for the purification and characterization of the polygalacturonases (PG) produced by Fusarium...

Development of a personal computer-based reactivity meter for a research reactor

Creator:: Bakir, Alla J. M.
Abstract:: A personal computer with a Data Acquisition and Control Adapter interface has been used to monitor the power of the Oregon State University TRIGA Reactor, and from the time behavior of the reactor power the reactivity has been computed using the point kinetics equations and displayed on a digital read-out...
