Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...
A majority of eighteenth-century novels remain in regular print over two hundred years since their inception. Yet with the possible exception of Robinson Crusoe, they have largely fallen out of popularity, rarely appearing on "The Summer's Hottest Reading" lists or receiving celebrity endorsement. I consider Ian Watt's foundational study, The...
After three decades of active research coupling hydrology and stream ecology, the connection among solute transport, metabolism and processing is still unresolved. These knowledge gaps obscure the functioning of stream ecosystems and how those ecosystems interact with other landscape processes. We must resolve these challenges to wisely manage water resources,...
Histones are presumed to be of chromosomal origin and provide
both structural and functional elements for chromatin. In like
manner the ribosomal proteins are of ribosomal origin and have
analogous roles. Considerable controversy over their cellular roles
exists because of the inability to compare directly both groups of
proteins. In...
A recorded image is a degraded version of an original image.
The process of removing the degradations is called restoration. Two
types of degradations are considered in this thesis: namely, linear
motion and defocused lens blurrings. Using the direct deconvolution
technique to restore blurred images is impossible if the blurring...
A microprogramming teaching tool was designed and implemented. This tool was based on the Am 2900 bitslice microprocessor family. It provides tools for understanding software development for a simple bitslice microprocessor.
Using historical maps and tools provided by GJS, the spatial patterns of
pre-logging forest conditions were quantified for three landscapes in western
Oregon. The spatial coincidence between forest patches and topographic
features was determined for slope gradient, aspect, elevation, and distance
from streams. Pre-logging and current forest compositions were compared....
In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...
The Spillways is a collection of poetry investigating a wide range of themes: identity, memory, loss, illness, labor, suffering, and grief. At times, the poems investigate place−in the physical and natural world−as a driving force of the speaker's identity. Many of the poems also consider the role of work and...
