This thesis seeks to explain how Lord George Gordon
Byron achieves catharsis through the writing of his truth
in Don Juan. In the poem the narrator expresses Byron's
innermost emotion while at the same time the protagonist,
Juan, relates to readers on a more conscious level. The
ability that Byron...

I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
Subterranean clover (Trifolium subterraneum L.) seed production
practices in Oregon are different from those in Australia.
There, seed is produced on fields which are managed primarily for
forage. In Oregon, seed fields are managed for seed as the primary

The degenerate nature of the metric on null hypersurfaces creates many difficulties
when attempting to define a covariant derivative on null submanifolds. This dissertation
investigates these challenges and provides a technique for defining a connection on null
hypersurfaces in some cases. Recent approaches using decomposition to define a covariant
derivative...
Low levels of copper have been shown to impair the olfactory system of threatened and
endangered (T&E) salmon, decreasing their predator avoidance behavior and likely
increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion
