Deoxyribonucleoside triphosphate (dNTP) concentrations measured in cells are not symmetric. dGTP almost always represents only 5-10% of the total dNTP pools in cells. In an in vitro replication system involving semiconservative replication from an SV 40 origin, the mutation frequency of an M13 phagemid replicated by human cell extracts in...
In this project, I explore the use of monomania as a literary and rhetorical device that pathologizes deviance from certain norms—in this case, sexual and political norms— and allows for contradiction, dissonance, and reform. Using Nathaniel Hawthorne’s short story “The Birthmark” and Edmund Clarence Stedman’s poem “How Old Brown Took...
Sandy beaches and dunes cover approximately one-third of the world’s ice-free coastlines and provide ecosystem services including coastal protection, recreation, wildlife habitat, and carbon sequestration. These dynamic interface habitats are variably shaped by wind, waves, sedimentary processes, and vegetation feedbacks. Positive biophysical feedbacks lead to the formation of vegetated coastal...

In order to develop effective interventions designed to encourage more
middle-aged individuals to engage in regular exercise, there is a need to
further understand the mechanisms involved in the decision to exercise.
One appropriate conceptual framework involves future-oriented self-conceptions,
or possible selves (Markus & Nurius, 1986). Possible selves, both
hoped-for...
Civil engineers frequently use lime to improve the mechanical properties of weak clayey soils. The production of lime is associated with significant CO₂ emissions. Sequestering carbon dioxide into the stabilized soil can effectively reduce the carbon footprint of the lime. In the presence of CO₂, unreacted lime in the stabilized...
Given the high risk of relapse during the first year of exercise involvement, it is
important to determine the processes of self-motivation which enable novice exercisers to

The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...
Atomic layer deposition (ALD) is an enabling technique for many new micro- and nanoscale technologies. The self-limiting surface chemical reactions by which ALD fundamentally operates give rise to uniquely high precision (atomic) control over deposited film thickness, uniformity over large areas, and conformality over complex and extreme topographies. One such...
As a metafictional work of science fiction literature, A Novel Elysium explores the timelessness of
both the human mind and its literary surroundings, comparing the self-awareness of its characters to
the sometimes tragic or empowering metaphysical realizations of human beings. Within this
framework, any concrete place or time is unimportant;...

A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...
Pacific lamprey (Lampetra tridentata) have historically been considered by the Western scientific community as a "trash" fish and generally overlooked in West Coast fisheries management. Recent population declines in Pacific Northwest streams have triggered new research to understand the life history and ecological significance of this species. These new studies...
Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...
Strong ground motions from earthquakes can result in the reduction of the shear modulus and wave propagation characteristics of soils, and can produce liquefaction and cyclic softening during shaking and for some time following the seismic event. While the ground motions produced from controlled blasting are different than those in...
William James came of age at a time of great social and intellectual change in the United States. During this period, new professional identities proliferated, and a new culture of professionalization developed with important ramifications for conceptions of individual and social identity. Professionalization was also closely related to key intellectual...
DOUBLE EXPOSURE is a novel concerned with the phenomenon of memory. The story explores such questions as: To what extent does "memory" (and the narratives we construct from it) explain who we are? How is memory influenced by others-and does it matter if it is? Can a memory that is...
Thomas Stearns Eliot’s 1922 modernist poem The Waste Land presents itself as an alternative to the decaying society Eliot found himself inhabiting. It begins as a personal means of pulling together one’s fragmented consciousness, but in doing so Eliot manages to present a solution to a world of selfishness—looking beyond...
