The work in this thesis involves the development of specimen preparation techniques for the observation with an electron microscope of alpha
particle tracks in cellulose nitrate plastic.
Both direct observation
using thin films and replica production techniques were investigated.
Direct observation of the alpha tracks was accomplished by cutting
thin...
Phenylketonuria (PKU) is a genetic inborn metabolic disorder which inhibits the functional production of the enzyme phenylalanine hydroxylase (PAH). It currently affects one in 15,000 Americans and is the most common amino acid metabolism error found in newborns. Individuals affected with PKU are incapable of metabolizing the amino acid, phenylalanine...
While much has been written about why people join social movements in general, little has been written about why people specifically join either militant or nonviolent social movements. Using the Black Panther Party as an example of a militant social movement and the mainstream Civil Rights Movement as an example...
This thesis situates a discussion of Thoreau's later natural history essays in the context of the author's other writings. Beginning with an examination of the writings of Thoreau's friend and mentor Ralph Waldo Emerson, this paper examines Thoreau's relation to and departure from Emerson's understanding of time, place, and pattern...
Zora Neale Hurston was a Black American writer
during the period of the Harlem Renaissance. The
purpose of this study is to show that three of her four
novels form a protracted discussion of a particular
type of freedom which was of especial interest to
Hurston. The study seeks to...
Recent conflicts in America concerning the environment (the harvesting of old growth timber in the Pacific Northwest, or the proposed opening of public lands in southern Utah to mining interests, for instance) have precipitated a personal examination of "historical others" (Jensen 64), individuals that possess very different sensibilities from a...
Five solvents were used to resolubilize the fungal pigments of Chlorociboria aeruginosa and Scytalidium cuboideum, two common fungi used in the spalting of wood pieces. These solvents were tested as a replacement for dichloromethane in the pigment application process, via analysis of their ability to increase internal color coverage inside...

Abstract: Five solvents were used to resolubilize the fungal pigments of
The protagonists in the fiction of Paule Marshall, Alice Walker, and Toni
Morrison illuminate American cultural perceptions of black women and illustrate how the
creators of these characters hope to change those perceptions. I studied Paule Marshall's
Daughters, Alice Walker's Meridian and The Color Purple, and Toni Morrison's The
Bluest...
This paper defends a reading of Hennan Melville's Moby-Dick that elevates Ishmael's status from mere narrator of Ahab's tragedy to that of protagonist of his own story, a novel of epistemological seafaring. As a metaphysical quester, Ishmael provides the novel's only reliable and complex vision of the condition of man...
Reactor refueling is a computationally intensive
problem solving process that requires automation since
significant resources are expended upon the search for
an optimal core loading. Without imposing some
constraints upon the configurations investigated, an
extremely large number of prototype loadings may be
generated without discovery of an improved loading. As...
Gadolinium is an important element to the Nuclear Fuel Industry. Two
of the seven naturally occurring isotopes of gadolinium have very large
absorption cross sections for thermal neutrons. The isotopes of
¹⁵⁵
Gd
and
¹⁵⁷ Gd readily absorb thermal neutrons and transmute to
¹⁵⁶
Gd and
¹⁵⁸
Gd which are...
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...
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...
Ralph Ellison died without ever completing his second novel. After his death, the executor of his literary estate, John F. Callahan, edited Ellison's work into a novel published under the title Juneteenth. This thesis examines the problems posed by Ellison's posthumously released text, especially the issues of authorial intent and...
I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...
The Supreme Court Bar-the lawyers who argue before the US Supreme Court-has historically been an elite and exclusive group. This investigation examines the demographic make-up of the Supreme Court Bar in the Roberts Court and compares it to previous iterations of the Supreme Court Bar, as well as the national...
Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...
I investigated survival, movements, home range sizes, and habitat selection of pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon and northwestern Nevada from June 2005 to June 2007. I trapped 298 rabbits on four sites and fitted each with radio transmitters. More than 13,000 locations of telemetered rabbits were recorded. I...
In this thesis, I examine some of the relationships between hierarchy and community that exist in institutions. Within institutions, individuals are separated from one another and organized hierarchically based on arbitrary inequalities. In general, I discusses inequalities based on race, class, gender, sexual orientation, age, ability, etc. Institutions organized based...
