Nutritional Condition Of Elk In Rocky Mountain National Park, Louis C. Bender, John G. Cook Jul 2005

Nutritional Condition Of Elk In Rocky Mountain National Park, Louis C. Bender, John G. Cook

Western North American Naturalist

We tested the hypothesis that elk in Rocky Mountain National Park (RMNP) were at ecological carrying capacity by determining herd-specific levels of nutritional condition and fecundity. Ingesta-free body fat levels in adult cows that were lactating were 10.6% (s = 1.7; range = 6.2–15.4) and 7.7% (s = 0.5; range = 5.9–10.1) in November 2001 for the Horseshoe and Moraine Park herds, respectively. Cows that were not lactating were able to accrue significantly more body fat: 14.0% (s = 1.1; range = 7.7–19.3) and 11.5% (s = 0.8; range = 8.6–15.1) for the Horseshoe and Moraine …

Monitoring Temporal Change In Riparian Vegetation Of Great Basin National Park, Erik A. Beever, David A. Pyke, Jeanne C. Chambers, Fred Landau, Stanley D. Smith Jul 2005

Monitoring Temporal Change In Riparian Vegetation Of Great Basin National Park, Erik A. Beever, David A. Pyke, Jeanne C. Chambers, Fred Landau, Stanley D. Smith

Western North American Naturalist

Disturbance in riparian areas of semiarid ecosystems involves complex interactions of pulsed hydrologic flows, herbivory, fire, climatic effects, and anthropogenic influences. We resampled riparian vegetation within ten 10-m × 100-m plots that were initially sampled in 1992 in 4 watersheds of the Snake Range, east central Nevada. Our finding of significantly lower coverage of grasses, forbs, and shrubs within plots in 2001 compared with 1992 was not consistent with the management decision to remove livestock grazing from the watersheds in 1999. Change over time in cover of life-forms or bare ground was not predicted by scat counts within plots in …

Land Grabbers, Toadstool Worshippers, And The Sagebrush Rebellion In Utah, 1979-1981, Jedediah S. Rogers Jul 2005

Land Grabbers, Toadstool Worshippers, And The Sagebrush Rebellion In Utah, 1979-1981, Jedediah S. Rogers

Theses and Dissertations

In 1979, a handful of Nevada state officials sparked a movement to transfer the large unappropriated domain to the western states. For two years what became known as the Sagebrush Rebellion swept across the American West like brushfire, engaging westerners of all stripes in a heated dispute over the question of the public lands. In Utah, as elsewhere in the West, public officials, rural ranchers, miners, developers, academics, environmentalists, and concerned citizens joined the debate and staked sides. This episode underscored western relationships between people and nature and featured contests over competing ideologies in the West. But it probably did …

Angiotensin Ii-Mediated Regulation Of The Human Angiotensin Ii Type 1 Receptor Gene, Xylophone Vijai Aasee Victor Jul 2005

Angiotensin Ii-Mediated Regulation Of The Human Angiotensin Ii Type 1 Receptor Gene, Xylophone Vijai Aasee Victor

Theses and Dissertations

The physiological responses of angiotensin II (Ang II) are mediated across the cell membrane through the angiotensin II type 1 receptor (AT1R), a heptahelical membrane protein coupled to trimeric G-proteins on the cytosolic side. AT1R on binding its ligand, Ang II, leads to downregulation of cell-surface receptor and also its mRNA. We have investigated whether the 3'- and 5'-untranslated regions of the human AT1R mRNA mediate the degradation of hAT1R mRNA by post-transcriptional mechanisms in human adrenocortical carcinoma cell line (H295R cells). Protein kinase C (PKC) activator, phorbol-12-myristate-13-acetate (PMA), showed that the downregulation of hAT1R mRNA is mediated by the …

Visualizing And Interacting With Externally Coupled Engineering Analysis Results, Paul Frederick Nelson Jul 2005

Visualizing And Interacting With Externally Coupled Engineering Analysis Results, Paul Frederick Nelson

Theses and Dissertations

Visualizing and interacting with engineering analysis results can provide valuable insights into a system's performance and aid in engineering decision-making. Currently, the majority of analysis codes are developed as isolated solutions focusing only on the most prominent physical influence to a system, such as thermal, structural, fluid, etc. Frequently, more than one of these physical influences combined to force engineers to evaluate complex, coupled systems. Coupled analysis codes are becoming more common place tools for engineers demanding high fidelity simulations of complex systems. External code coupling solutions are emerging to permit generic coupling of separate, world class CAE solvers thus …

Development Of A Model For The Kinetics And Mechanism Of Nitrogenase, Phillip E. Wilson Jul 2005

Development Of A Model For The Kinetics And Mechanism Of Nitrogenase, Phillip E. Wilson

Theses and Dissertations

Nitrogenase has a central role in the global nitrogen cycle as the enzyme that catalyzes the reduction of atmospheric N2 to NH3. Fixed nitrogen is generally limiting in the environment and in agriculture, so nitrogenase has received much attention as an alternative to nitrogen fertilizers. Characterizing the mechanism of nitrogenase is the goal of this work. The molybdenum nitrogenase enzyme system is comprised of the MoFe protein and the Fe protein. Interactions between these proteins and nucleotides are crucial to catalysis. An important approach to characterize these interactions is to correlate the kinetics of nitrogenase catalysis to a mechanism based …

Homologous Strand Exchange And Dna Helicase Activities In Plant Mitochondria, Daqing Song Jul 2005

Homologous Strand Exchange And Dna Helicase Activities In Plant Mitochondria, Daqing Song

Theses and Dissertations

Homologous recombination is critical for generating genetic variation in living organisms by exchange and rearrangement of DNA. Most of our knowledge about homologous recombination is limited to processes in bacteria or in eukaryotic nuclei. In E. coli, homologous recombination is dependent on the RecA protein. Higher plant chloroplasts have RecA-like strand exchange activity. However, little is known about these mechanisms in higher plant mitochondria. I have detected a RecA-like strand exchange activity in soybean mitochondria. This activity forms joint molecules in the presence of ATP, Mg2+, and homologous DNA substrates. In addition, the E. coli single-stranded DNA binding (SSB) protein …

How Virtues And Values Affect Marital Intimacy, Natalie Jan Stevens Jul 2005

How Virtues And Values Affect Marital Intimacy, Natalie Jan Stevens

Theses and Dissertations

The purpose of this study was to better understand how virtues and values affect marital intimacy. Ten married couples were given a marital satisfaction assessment and participated as individuals in 1-1/2 hour interviews which were audiotaped and then transcribed. Using grounded theory and also the constant comparative method, researchers were able to generate a theory involving a core theme of showing love for self and other, which strongly contributes to increased intimacy. This process is connected to living virtues and to becoming other-oriented. Two different ways of "being" were found to be connected both with showing love, living virtues, increasing …

Accelerated Ray Traced Animations Exploiting Temporal Coherence, Darwin Tarry Baines Jul 2005

Accelerated Ray Traced Animations Exploiting Temporal Coherence, Darwin Tarry Baines

Theses and Dissertations

Ray tracing is a well-know technique for producing realistic graphics. However, the time necessary to generate images is unacceptably long. When producing the many frames that are necessary for animations, the time is magnified. Many methods have been proposed to reduce the calculations necessary in ray tracing. Much of the effort has attempted to reduce the number of rays cast or to reduce the number of intersection calculations. Both of these techniques exploit spatial coherence. These acceleration techniques are expanded not only to exploit spatial coherence but also to exploit temporal coherence in order to reduce calculations by treating animation …

Microbial And Chemical Affects On Leachate From Calcareous Soils Treated With Wastewater Effluent, Craig M. Paul Jul 2005

Microbial And Chemical Affects On Leachate From Calcareous Soils Treated With Wastewater Effluent, Craig M. Paul

Theses and Dissertations

Increasing human populations are placing greater strain on water resources, prompting the use of treated wastewater effluent for irrigation in some areas, including the desert regions of the Western United States. To determine the potential effects of using secondary effluent for irrigation, we applied wastewater effluent and irrigation waters to natural and artificially constructed calcareous soils in greenhouse and field lysimeters, and in soil columns. The leachate from one field lysimeter contained increased fecal coliform counts than the effluent. Leachate coliform counts were decreased or not significantly changed in two field lysimeters. Electrical conductivity (EC), sodium adsorption ratio (SAR), chloride …

Tauser Killed Both Dogs And Other Suburban American Family Folklore, Kristina Whitley Gashler Jul 2005

Tauser Killed Both Dogs And Other Suburban American Family Folklore, Kristina Whitley Gashler

Theses and Dissertations

This thesis attempts to answer the questions "What purposes do family pets and the narratives we tell about them serve in modern American society?" and "What do these stories tell us about what Americans value and about where we locate our ‘value center’?" In Chapter 1, I discuss how Americans define loyalty in our pets now that our animals generally no longer help us work. I conclude that since the shift from agricultural to suburban settings, animals prove their loyalty individually and in human-like ways, rather than as "good" members of their own species, but at the same time because …

Phylogeny And Biogeography Of Ice Crawlers (Insecta: Grylloblattodea): Evidence From Six Molecular Loci, Karl J. Jarvis Jun 2005

Phylogeny And Biogeography Of Ice Crawlers (Insecta: Grylloblattodea): Evidence From Six Molecular Loci, Karl J. Jarvis

Theses and Dissertations

Ice crawlers (Insecta: Grylloblattodea) are rarely encountered insects that consist of five genera representing 26 species from North America and Asia. Asian grylloblattids are the most diverse, but North American ice crawlers (genus Grylloblatta) are known for their adaptation to cold conditions. Phylogenetic relationships among grylloblattid species and genera are not known. Late Pleistocene glaciations had a major effect on the current Grylloblatta distribution, because their specific habitat requirements restrict them to small geographical areas. Six genes were sampled in 37 individuals for 18S rRNA, 28S rRNA, histone 3, 12S rRNA, 16S rRNA, and cytochrome oxidase II (COII) from 27 …

Crustacean Phylogenetic Systematics And Opsin Evolution, Megan L. Porter Jun 2005

Crustacean Phylogenetic Systematics And Opsin Evolution, Megan L. Porter

Theses and Dissertations

Composed of a chromophore bound to an integral membrane protein (opsin), visual pigments are phenotypically characterized by the wavelength of maximal absorption (λmax). The underlying molecular mechanism controlling λmax is the interaction between the opsin amino acid sequence and the chromophore. While a plethora of studies have looked at structure/function relationships in vertebrate opsins, fewer studies have investigated similar issues in invertebrates. Furthermore, those few studies undertaken in invertebrate systems suggest different mechanisms of spectral tuning and photoactivation compared to vertebrate systems. This dissertation research is focused on expanding our knowledge of opsin evolution in invertebrate systems, particularly from non-insect …

Assessment Of Cell Death Parameters In Bovine Parvovirus-Infected Ebtr Cells, Lubna Salah Eldin Abdel Latif

Theses and Dissertations

Bovine parvovirus (BPV) is a helper-independent parvovirus. It has a small icosahedral capsid with a single stranded DNA genome. It is a highly stable virus with a narrow host range. It causes acute gastroenteritis in calves. It is considered to be a cytolytic virus because it kills the host cells. However, the mechanism by which the virus causes cell death is not known. The work described in this thesis assessed different parameters of cell death in BPV infected embryonic bovine tracheal (EBTr) cells. There are several ways for viruses to induce cell death. Viruses can induce apoptosis in the infected …

Fortune Personified And The Fall (And Rise) Of Women In Chaucer's Monk's Tale And The Autobiographical Writings Of Christine De Pizan, Leona C. Fisher Jun 2005

Fortune Personified And The Fall (And Rise) Of Women In Chaucer's Monk's Tale And The Autobiographical Writings Of Christine De Pizan, Leona C. Fisher

Theses and Dissertations

This thesis will posit that a query of the medieval trope, Fortune, can be read as a query into femininity. Fortune is depicted with many quintessentially medieval feminine traits, and women in texts that discuss Fortune often have Fortune's traits. While texts that link Fortune and femininity usually do so to censure women, some writers turned the trope to their advantage for just the opposite purpose. Both Chaucer in the "Monk's Tale" and Christine de Pizan personify Fortune to subtly point out the flaws in antifeminist medieval view of women. This thesis explores the ways in which these writers cleverly …

Autologous Fibrinogen Purification And Concentration For Use In Fibrin Sealant, Steven M. Alston Jun 2005

Autologous Fibrinogen Purification And Concentration For Use In Fibrin Sealant, Steven M. Alston

Theses and Dissertations

Fibrinogen concentrates are used widely as a sealant during and after surgery to reduce blood loss. Commercially available fibrin sealants are made from pooled human blood, which carries the risk of blood-borne diseases, and are expensive. These concerns have brought to focus the need for autologous fibrinogen concentrates. This need has been addressed by utilizing a unique approach in which fibrinogen is precipitated from plasma with protamine. The physical properties of fibrin sealant prepared from fibrinogen precipitated with protamine were evaluated. The optimal precipitation conditions included a plasma protamine concentration of 10 mg/mL at room temperature. Under these conditions 96% …
