Accumulation of dietary polychlorinated biphenyl by rainbow trout (Salmo gairdneri)

Creator:: Lieb, Andrew James
Abstract:: This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...

Age, chemistry, and tectonic significance of Easter and Sala y Gomez Islands

Creator:: Clark, James Gregory, 1948-
Abstract:: Easter Island and Sala y Gomez are part of the Sala y Gomez Ridge, a broad band of high topography and scattered seamounts extending ESE from the East Pacific Rise. It has been proposed that the Sala y Gomez Ridge results from the movement of the Nazca Plate over a...

On the structure of minimum surfaces at the boundary

Creator:: Tjoelker, Cornelius Henry
Abstract:: In this paper we consider the behavior of certain surfaces at certain boundary points. The surfaces under consideration satisfy a topological definition and are of 2-dimension in 3-dimensional Euclidean space with the boundary a finite set of straight line segments. It is shown that the surface of minimum area with...

The design, construction and calibration of a low-energy, low exposure-rate ionization chamber

Creator:: Clarke, Arthur Porter
Abstract:: A low-energy, low-exposure-rate, guarded-field ionization chamber system with a sensitive volume of approximately 1040 cm³ and an exposure-rate range from 60 mR/h to less than 0.5 mR/h was designed, constructed and calibrated. The calibration was effected by constructing and calibrating a 60 cm³ volume transfer chamber of similar design against...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

Direct shear testing of UO₂ sphere-pac nuclear reactor fuel

Creator:: Jenks, Richard P.
Abstract:: The design, development, and utilization of a direct shear test apparatus is presented in this thesis. The effectiveness of the device for determining the friction angle stress state parameter is studied. Two materials, alumina and uranium dioxide, were tested. Alumina microspheres were employed in the initial experiments to simulate the...

Exploring the Effectiveness of Providing Structured Design for the Environment Knowledge during the Conceptual Design Phase

Creator:: Ross, Donovan Arie
Abstract:: The fuzzy front end of engineering design can present a difficult challenge, and as such, recent engineering design research has focused on guiding and influencing the way a designer ideates. Early ideation can be especially difficult when attempting to integrate specific design objectives in product design, called Design for X...
