Upper Extremity Kinematics and Joint Coordination of Fly-Casting: Author: Allen, Joshua Ryan; Date: 2006-08-15; Program: Health and Human Development; Abstract: Little research exists that focuses on the motions and coordination common to fly-casting. It was hypothesized that kinematic parameters of casting (peak and total range of motion, timing of peak joint angular velocity, and magnitude of peak joint angular velocity) would increase in order to cast lines of greater length. Also, it was hypothesized that when greater length of line is cast, the time between peak angular velocities would decrease. The purpose of this study was to determine the kinematic and joint coordination changes necessary to cast lines of different length. Eighteen male subje...; Download File | View full details

Strange Bedfellows: Science and Storytelling for Broadcast Television: Author: Bell, Andrew Wade; Date: 2006-08-15; Program: Science and Natural History Filmmaking; Abstract: Filmmakers exploring natural science subject matter that want to sell their work to broadcast television or theatrical outlets face a difficult challenge. They must somehow conflate two contradictory elements: natural science information and compelling storytelling. Looking at the roots of classical narrative, we can better understand why audiences have come to crave it. Broadcast television, in turn, caters to audience desire. This combination forces filmmakers to present natural science information in an exciting way, and has led filmmakers to employ time-honored narrative structures as orga...; Download File | View full details

A Validation Study of the Montana State University In-Plane Loader: Author: Collett, Aaron Bruce; Date: 2006-08-15; Program: Mechanical Engineering; Abstract: Characterizing a polymer composite material's response to loading beyond the elastic region is less well defined than it is for other structural materials such as metals. The Naval Research Laboratory has developed a method that uses dissipated energy as a metric to facilitate this characterization. The method relies on empirical data from material strength tests as well as finite element analysis data to make the prediction. A substantial amount of empirical data from different loading conditions is needed to characterize a material. This warrants a testing machine that can apply several load...; Download File | View full details

Their structural complexity and importance of these compounds as therapeutical agents have made them attractive targets for synthetic organic chemists.¹ Excellent chiral propionate reagents have been developed over the years, ...; Download File | View full details

Analysis of Pseudomonas aeruginosa Virulence in Modeled Microgravity Conditions: Author: Guadarrama-Beltran, Seratna; Date: 2006-08-15; Program: Microbiology; Abstract: Spaceflight conditions may enhance bacterial growth, alter antimicrobial susceptibility and possibly affect virulence. Since spaceflight causes astronauts to experience secondary immunosuppression, increased virulence would increase the risk of infection. Limited opportunities for spaceflight experiments necessitate ground-based simulations. Clinostats and rotating wall vessel bioreactors, e.g. High Aspect Ratio Vessels (HARVs) are used to simulate microgravity effects at 1xg. Clinostat and HARV rotation on the horizontal axis results in the g-vector being time averaged to near zero. In contro...; Download File | View full details

Clarkia: Genetic Basis of Sister Species Divergence Clarkia concinna x Clarkia breweri: Author: Henry, Amanda Ann (Shaffer); Date: 2006-08-15; Program: Plant Sciences; Abstract: The genetic changes accompanying speciation provide insight into the mode and tempo of phenotypic divergence.

Static and Dynamic Behavior of Stress Coated Membranes: Author: Nandurkar, Kuldeep Pandurang; Date: 2006-08-15; Program: Mechanical Engineering; Abstract: Large space mirrors need to be made of ultra-lightweight materials (membranes) that have very low densities and high flexibility (compliance) for packaging. A coating application necessary for optical reflectivity may also impart to these ultra-lightweight materials a desired shape and to help maintain that shape in the harsh environment of space. When a coating is applied on the membrane substrate, stresses develop in the coating due to atomistic processes. These stresses are fundamental to the final shape of the substrate. Coatings applied to the substrate in order to maintain a particular s...; Download File | View full details

Common Loon Nesting Ecology in Northwest Montana: Author: Paugh, Justin Isaac; Date: 2006-08-15; Program: Fish and Wildlife Management; Abstract: Common Loons (Gavia immer) are found across the northern continental United States and in Canada and Alaska. The common loon is long lived, with delayed breeding maturity and low fecundity. Surveys indicate Montana's Common Loon population remains stable, but lakeshore development and watercraft recreation are increasing. While the effects of these changes are unclear, research investigating reproductive success over a gradient of habitat conditions, at multiple spatial scales is lacking. The objectives of this research were to investigate vital rates and the relationships between daily nest s...; Download File | View full details

Reclamation Effectiveness at Three Reclaimed Abandoned Mine Sites in Jefferson County, Montana: Author: Tafi, Tara Christine; Date: 2006-08-15; Program: Land Rehabilitation; Abstract: Montana has an estimated 6000 abandoned mine sites, many with associated waste rock and tailings materials contributing to the release of high levels of acidity, heavy metals, and other contaminants, creating a risk to human health and the environment.

Protein Cage Architectures as a Nano-Platform for Material Synthesis and Metal Binding: Author: Allen, Mark Andrew; Date: 2006-08-15; Program: Chemistry; Abstract: Supramolecular proteins that assemble into cage like architectures have been used for nano-material synthesis and as a scaffold for metal binding. Material synthesis can be performed by exploiting the cage-like properties of these nano-containers and relying on the electrostatically distinct interior environment that drive mineral encapsulation. Ferritin and ferritin like proteins can be used as size constrained reaction vessels that encapsulate materials that have sizes that are determined by the internal dimensions of the protein cage. These range from 5 nm for the ferritin like protein from...; Download File | View full details

A Matter of Life and Death: Rethinking Evolution and the Nature of Science on Television: Author: Bard, Susanne Clara; Date: 2006-08-15; Program: Science and Natural History Filmmaking; Abstract: In a world where antibiotic resistance can make bacterial infections deadly and the HIV virus constantly mutates inside the human body, an understanding of evolution and its mechanisms is increasingly important. Yet much of the public is still either hostile to or misunderstands evolution and its mechanisms. Television provides the bulk of the general public's exposure to science once formal education has ended. The rhetorical strategies employed by much of science and evolution programming, along with an emphasis on content over process, delivers the message that science is a search for absol...; Download File | View full details

Spatio-Temporal Dynamics of the Central Bison Herd in Yellowstone National Park: Author: Bruggeman, Jason Edward; Date: 2006-08-15; Program: Fish and Wildlife Biology; Abstract: The spatio-temporal dynamics of Yellowstone National Park bison (Bison bison) are complex and affected by multiple abiotic and biotic mechanisms. In the Madison- Firehole area, which provides winter range for the migratory central herd, this suite of effects is particularly intricate owing to geothermally influenced habitats, severe winter climate, and variability in resource distribution. Understanding factors influencing bison spatio-temporal dynamics is of importance to Yellowstone, which is faced with managing a growing bison population that is expanding its range.

Extensive research in teaching and learning science also shows that a conceptual change model of teaching is effective in helping students learn science. Finally, research into how Hispanic students learn best has provided a number of suggestions for science instruction. The Inquiry ...; Download File | View full details

Creating Space for Science and Celebrity in the Public Discussion of Climate Change: Author: DeWitt, Sarah Louise; Date: 2006-08-15; Program: Science and Natural History Filmmaking; Abstract: Climate change is one of the most prominent topics in news, politics, and popular culture today. For many years the topic has been presented as an unresolved debate between believers and skeptics, leading to a perpetual state of confusion and helplessness in the public eye. In the past eight months newspapers and magazines have begun to suggest that the climate change debate is over. The scientific consensus agrees that climate change is happening and it is the result of human influence on the Earth's atmosphere. Yet this consensus has not effectively translated into the public consciousness. ...; Download File | View full details

Frequency Stabilization of an External Cavity Diode Laser Employing Digital Control: Author: Drollinger, Cy Taylor; Date: 2006-08-15; Program: Electrical Engineering; Abstract: Optical signal processing can span across bandwidths of hundreds of GHz with resolutions in the kHz range. This can be done by using spectral hole burning materials. A limiting factor in the frequency resolution is the bandwidth of the laser driving the spectral hole burning material. Better control techniques of laser jitter will decrease laser line width and increase frequency resolution of optical processing. This thesis explores the digital control technique of inherent noise in an external cavity diode laser and the use of reconfigurable platform to prototype digital implementation....; Download File | View full details

The goal of this research was two fold; 1) to develop a three dimensional numerical model, incorporating the viscoelastic material description of biofilm, to simulate the response of biofilm to varying hydrodynamic conditions and 2) use this model to identify behavi...; Download File | View full details

Generic Properties of the Infinite Population Genetic Algorithm: Author: Hayes, Christina Savannah Maria; Date: 2006-08-15; Program: Mathematics; Abstract: The infinite population model for the genetic algorithm, where the iteration of the genetic algorithm corresponds to an iteration of a map G, is a discrete dynamical system. The map G is a composition of a selection operator and a mixing operator, where the latter models the effects of both mutation and crossover. This dissertation examines the finiteness and hyperbolicity of fixed points of this model. For a typical mixing operator, the fixed point set of G is finite and all fixed points are hyperbolic....; Download File | View full details

Evaluation of a Web-Based Tool for Ungulate Harvest Management: Author: Kenyon, Jr., Marc Wayne; Date: 2006-08-15; Program: Animal and Range Sciences; Abstract: Hunting the female segment of a wild ungulate population is an effective wildlife management tool to control overpopulation. Most hunters prefer to harvest males however, limiting success in controlling overpopulation. Landowners attempting to manage wild ungulate overpopulation have expressed difficulty with finding hunters who wish to harvest female ungulates. Likewise, some hunters willing to harvest female ungulates have difficulty locating private landowners seeking hunters.
