This study examined features of deep pool (>0.8 m mean depth) used by
adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had
a heterogenous thermal profile, with some segments exceeding preferred
temperature of steelhead. Deep pools were scarce (4% of the total habitat units)
and 39% of them were...
As structural durability analysis is increasingly trusted during the design processes of the automotive industry, more complete and sophisticated modeling of material behavior under both static and dynamic loading conditions is paramount. This is especially true regarding the application of heavy-duty trucks, where modern designs contain large parts such as...
I studied developmental rates in a suite of temperate and tropical passerine bird species from the New World to test the hypothesis that tropical passerines exhibit slower patterns of growth and development than temperate birds. I also investigated how the expression of several developmental rates varied with life history traits...
The most abundant clone found in ribosomal RNA clone libraries obtained from the world's oceans belongs to the SAR11 phylogenetic group of environmental marine bacteria. Imaging and counting SAR11 bacterial cells in situ has been an important research objective for the past decade. This objective has been especially challenging due...
This study describes the composition of forest landscapes surrounding
northern spotted owl (Strix occidentalis caurina) nests in the central Cascade
Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair
territories with forest composition around 119 points drawn randomly from all
terrestrial cover-types, and around 104...
Magnetically programmable surface acoustic wave (MP SAW) devices were designed, fabricated and characterized in this thesis using integrated giant magnetoresistive (GMR) bits with interdigital reflectors. This provides a proof of concept of a novel storage element on radio frequency identification tags. Interdigital transducers (IDTs) on a piezoelectric substrate are used...
