- Emergence and growth of seven grass species across a gradient of metals and arsenic in lime-amended contaminated soils
- Author: Martin, Tara Noel
- Date: 2009-08-15
- Program: Land Rehabilitation
- Abstract: Montana's Upper Clark Fork River Basin contains hundreds of square kilometers of land impacted by mine wastes and/or smelter emissions from decades of copper mining and related activities. Contaminated soils in the Basin are often acidic and highly enriched with the trace elements cadmium, copper, arsenic, lead, zinc, and others. Natural plant colonization is often impaired, as evidenced by barren areas that are so phytotoxic that normal germination and establishment cannot occur. One reclamation strategy being used is in-place treatment with soil amendments including lime and other products. ...

- Connections: making sense of the world around us (the use of music in documentary films)
- Author: Glover, Kristin Lynn
- Date: 2009-08-15
- Program: Science and Natural History Filmmaking
- Abstract: Music is often a neglected and undervalued element in documentary films. This thesis looks at music cognition, film cognition, and learning theory to argue for the importance of music in documentary films. Adhering to the theory that the documentary film genre is an educational tool first and foremost, the use of music strengthens a film's potential to engage with and educate an audience. The first portion of this thesis examines brain function as it pertains to music and learning, as well as research in narrative film cognition, looking particularly at how documentary films provide a unique m...

- Classical mechanics with dissipative constraints
- Author: Harker, Shaun Russell
- Date: 2009-08-15
- Program: Mathematics
- Abstract: The aim of this thesis is to consider the mathematical treatment of mechanical systems in the presence of constraints which are energetically dissipative. Constraints may be energetically dissipative due to impacts and friction. In the frictionless setting, we generalize Hamilton's principle of stationary action, central to the Lagrangian formulation of classical mechanics, to reflect optimality conditions in constrained spaces. We show that this generalization leads to the standard measure-theoretic equations for shocks in the presence of unilateral constraints. Previously, these equations we...

- Ichthyoplankton density and Shovelnose sturgeon spawning in relation to varying discharge treatments
- Author: Goodman, Benjamin Joseph
- Date: 2009-08-15
- Program: Fish and Wildlife Management
- Abstract: Many lotic fish species use natural patterns of variation in discharge and water temperature as spawning cues and these natural patterns are often altered by river regulation. The effects of spring discharge and water temperature variation on the spawning of shovelnose sturgeon Scaphirhynchus platorynchus and other fishes in the upper Missouri River have not been well documented. In 2006, 2007, and 2008, I had the unique opportunity to study the effects of experimental discharge levels on ichthyoplankton density in the lower Marias River, a regulated tributary to the upper Missouri River. The ...

- Reflexive filmmaking for wildlife and nature films
- Author: Hiemenz, Vanessa Serrao
- Date: 2009-08-15
- Program: Science and Natural History Filmmaking
- Abstract: Historically, wildlife and nature filmmakers have embraced the expository mode of filmmaking and a realistic style, attempting to influence their audience with compelling arguments. However, while their scripts may call for activism, their expository, realistic style, with hidden production methods, an authoritative tone, and pristine visuals, instead encourages voyeurism. In addition, standard theater and television distribution methods offer no outlet for action to viewers who do feel inspired. I offer a different model for influence in my wildlife series Nature Break: reflexive filmmaking. ...

- Magnetic resonance microscopy studies of biofilms: diffusion, hydrodynamics and porous media
- Author: Hornemann, Jennifer Ann
- Date: 2009-08-15
- Program: Engineering
- Abstract: Due to the complicated nature of studying living bacterial communities, Magnetic Resonance Microscopy (MRM) is a necessary tool providing unique data that is complementary to other techniques such as confocal microscopy and microelectrodes. MRM has the ability to probe an opaque system non-invasively and collect velocity measurements, imaging data, diffusion, and relaxation values and is an asset in the quest to learn how biofilms establish, grow, and die. The goal of these studies was to extend current biofilm research using MRM to enhance our understanding of transport phenomena over a hiera...

- The split-screen aesthetic: connecting meaning between fragmented frames
- Author: Ingrassia, Peter Matthew
- Date: 2009-08-15
- Program: Science and Natural History Filmmaking
- Abstract: The split-screen is a multi-frame technique used in film, television and video. Recent advances in digital technology make it easier to incorporate the fragmented frame into visual narrative strategies. I argue that properties inherent to the split-screen technique (including simultaneity, symmetry, visual irony, omniscient view and visual style) also emerge as attributes of a split-screen aesthetic. The split-screen aesthetic transforms a technical contrivance that has long provided an alternative to parallel editing, into a powerful narrative tool that facilitates the construction of visual ...

- Spatiotemporal relationship between climate and Whitebark pine mortality in the greater Yellowstone ecosystem
- Author: Jewett, Jeffrey Thomas
- Date: 2009-08-15
- Program: Land Resources and Environmental Sciences
- Abstract: Whitebark pine (Pinus albicaulis) serves as a subalpine keystone species by regulating snowmelt runoff, reducing soil erosion, facilitating the growth of other plants, and providing food for wildlife, particularly grizzly bears (Ursus arctos horribilis). Mountain pine beetle (Dendroctonus ponderosae) is an ideal bio-indicator of climate change, as its life cycle is entirely temperature dependent. Western North America is currently experiencing the largest outbreak of mountain pine beetle on record, and evidence suggests that a changing climate has accelerated the life-cycle of this bark beetle...

- Contributions of pneomococcal virulence factors to secondary Streptococcus pneumoniae infection following influenza infection
- Author: King, Quinton Oliver
- Date: 2009-08-15
- Program: Veterinary Molecular Biology
- Abstract: Influenza infection increases susceptibility to secondary infection with Streptococcus pneumoniae resulting in significantly increased morbidity and mortality. Whereas viral contributions to this synergism have been explored, little is known concerning contributions of the bacterium, specifically those provided through bacterial virulence factors. To assess the contributions of the known pneumococcal virulence factors hyaluronidase (Hyl), neuraminidase (NanA) and pneumococcal surface protein A (PspA) to secondary S. pneumoniae infection following influenza infection, mutants lacking these prot...

- Sensitivity of 1-D hydraulic models of fish passage in culverts to descriptions of fish swimming performance
- Author: Nixon, Kyle Marshall
- Date: 2009-08-15
- Program: Civil Engineering
- Abstract: One way culverts become barriers to the upstream movement of fish is by creating excessive velocities exceeding a fish's swimming ability. FishXing, a common tool for indirectly assessing fish passage, uses fish swimming ability information with one-dimensional culvert hydraulics to predict barrier status of culverts. However, since fish swimming ability data is scarce for many fish species, predictions of a culvert's barrier status can be inaccurate and overly conservative, possibly leading to misclassification or uneconomical design. Additional fish swimming ability research is necessary to ...

- Gene regulation in the lac operon
- Author: Patterson, Kathryn Grace
- Date: 2009-08-15
- Program: Mathematics
- Abstract: The lac operon, a jointly controlled series of genes in the bacteria E. coli, has been studied extensively since the 1940's. The lac operon genes are transcribed and then translated into proteins necessary for transport and digestion of lactose. The operon is activated in the presence of lactose after glucose, the preferred carbon source, has been expended. In this thesis, we introduce a biophysical model using the Shea-Ackers framework for modeling promoter dynamics. The model spans two scales: the inputs are biophysical parameters of molecular interactions and the result is a level of gene e...

- Minimum-data analysis of ecosystem service supply with risk averse decision makers
- Author: Smart, Francis Clayton
- Date: 2009-08-15
- Program: Applied Economics
- Abstract: There is a need for models that produce results that are both timely and sufficiently accurate to be useful to policy makers. The minimum-data approach of Antle and Valdivia (2006) responds to this need by supplying a spatially explicit first order approximation that models ecosystem supply by producers. However, producers in developing nations often are observed to deviate from simple expected profit maximization. Risk is one possible explanation for this divergence. This study builds upon the minimum-data approach by allowing for risk averse producer preferences. The study presents a framewo...

- Change in practice used to quantify breast milk intake of pre-term infants in a neonatal intensive care unit: test-weighing to 'Salt Lake Feed Plan'
- Author: Treloar, Allison Kirsch
- Date: 2009-08-15
- Program: Nursing
- Abstract: A local community hospital in Montana expressed a desire to establish a written clinical guideline for transitioning preterm infants from enteral gavage feedings to oral feedings. This desire was prompted by a change in the method of quantifying breast milk intake of preterm infants when transitioning them from enteral gavage feedings to at-breast feedings in a Neonatal Intensive Care Unit (NICU). The hospital changed from the practice of test-weighing as a clinical indicator to quantify breast milk intake to the "Salt Lake City Feed Plan". Procedures: Retrospective data from four co...

- Multicellular mathematical models of somitogenesis
- Author: Campanelli, Mark Benjamin
- Date: 2009-08-15
- Program: Mathematics
- Abstract: Somitogenesis is an important pattern formation process in the developmental biology of vertebrates. The phenomenon has received wide attention from experimental, theoretical, and computational biologists. Numerous mathematical models of the process have been proposed, with the clock and wavefront mechanism rising to prominence over the last ten years. This work presents two multicellular mathematical models of somitogenesis. The first is a phenomenological phase oscillator model that reproduces both the clock and wavefront aspects of somitogenesis, but lacks a biological basis. The second is ...

- Re-constructing dialogue: literary sensibility and non-violent subjectivity
- Author: Gunderson, Kory Marika
- Date: 2009-08-15
- Program: English
- Abstract: With this project, I seek to advocate the relevance of literary scholarship to the problem of the use of sanctioned violence to solve conflicts. I propose that, unlike the empirical sensibility, what I will call the literary sensibility is, at heart, a non-violent means for creating and recreating understanding. When the literary sensibility is used to negotiate the unknown into the known, each subjective participant in the encounter is able to grant and maintain his or her own integrity as well as the integrity of all other subjective participants as subjects. I define my understanding of the...

- Changes in temporal leptin concentrations and other metabolic factors in primiparous, postpartum, anestrous, suckled, beef cows exposed to bulls
- Author: Olsen, Jesse Riley
- Date: 2009-08-15
- Program: Animal and Range Sciences
- Abstract: Exposing cows to bulls or excretory products of bulls stimulates resumption of ovarian cycling activity in postpartum, suckled, anestrous cows. This biostimulatory effect may be mediated by pheromones produced by bulls that stimulate physiological changes in metabolic regulation of the hypothalamic-pituitary-ovarian (HPO) axis of cows. In Experiment 1, the hypotheses tested were that concentrations of glucose, NEFA, thyroxine (T4), tri-iodothyronine (T3), and T3:T4 ratios do not differ between cows exposed to bulls or steers. The biostimulatory effect of bulls was associated with lower mean co...
