This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...
An ancient pheromonal signal is found in aquatic courting salamandrids and terrestrial courting plethodontids, two highly divergent salamander families. In the aquatic courting salamandrids Cynops pyrrhogaster and C. ensicauda, the decapeptide sodefrin is cleaved from a larger 189 amino acid Sodefrin Precursor Factor (SPF) protein and released from a gland...
Part of the infrastructure of a disused mill in Dee, Oregon is being converted into a hydroelectric power station. A turbine and generator combination must be selected to match the flow and pressure at the bottom of the penstock. One old penstock route is being abandoned and replaced with a...
Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...
The infrastructure of a destroyed saw mill is being re-engineered. One project involves installing a micro hydroelectric power station at the end of an existing pipeline. The hydraulic power available to the generator was estimated. Much construction and engineering work has gone into the design and partial build of this...
The desire to apply short-range wireless communication systems to telemetry sensor
networks in a metal-enclosed chamber has prompted this study. This thesis will discuss
the design of an infrared (IR) communication system for a wireless low-power, low-data-
rate sensor network in a metal enclosure. This design requires an in-depth understanding...
