Identification Of An Il-17-Producing Nk1.1neg Inkt Cell Population Involved In Airway Neutrophilia, Paul B. Savage, Marie-Laure Michel, Alexandre Castro Keller, Christophe Paget, Masakazu Fujio, Francois Trottein, Chi-Huey Wong, Elke Schneider, Michael Dy, Maria C. Leite-De-Moraes Apr 2004

Identification Of An Il-17-Producing Nk1.1neg Inkt Cell Population Involved In Airway Neutrophilia, Paul B. Savage, Marie-Laure Michel, Alexandre Castro Keller, Christophe Paget, Masakazu Fujio, Francois Trottein, Chi-Huey Wong, Elke Schneider, Michael Dy, Maria C. Leite-De-Moraes

Faculty Publications

Invariant natural killer T (iNKT) cells are an important source of both T helper type 1 (Th1) and Th2 cytokines, through which they can exert beneficial, as well as deleterious, effects in a variety of inflammatory diseases. This functional heterogeneity raises the question of how far phenotypically distinct subpopulations are responsible for such contrasting activities. In this study, we identify a particular set of iNKT cells that lack the NK1.1 marker (NK1.1neg) and secrete high amounts of interleukin (IL)-17 and low levels of interferon (IFN)-{gamma} and IL-4. NK1.1neg iNKT cells produce IL-17 upon synthetic ({alpha}-galactosylceramide [{alpha}-GalCer] or PBS-57), as well …

Numerical Modeling Of Friction Stir Welding: A Comparison Of Alegra And Forge3, Alma H. Oliphant Apr 2004

Numerical Modeling Of Friction Stir Welding: A Comparison Of Alegra And Forge3, Alma H. Oliphant

Theses and Dissertations

The objective of this research was to evaluate the capabilities of ALEGRA, a Sandia National Labs hydrocode, and Forge3, a Transvalor S.A. product, to accurately model the Friction Stir Welding Process. ALEGRA and Forge3 are discussed in light of the inherent challenges of modeling Friction Stir Welding, and a rotational boundary condition is added to ALEGRA. Results are presented from Friction Stir Welding modeling outputs from both ALEGRA and Forge3. ALEGRA is shown to be incapable of modeling the Friction Stir Welding process, in large part due to its focus on shock propagation, which causes extremely small time steps. Forge3 …

Molecular-Dynamics Simulation Of The Effect Of Ions On A Liquid–Liquid Interface For A Partially Miscible Mixture, Richard L. Rowley, Kent E. Wardle, Eric Carlson, Douglas Henderson Apr 2004

Molecular-Dynamics Simulation Of The Effect Of Ions On A Liquid–Liquid Interface For A Partially Miscible Mixture, Richard L. Rowley, Kent E. Wardle, Eric Carlson, Douglas Henderson

Faculty Publications

Molecular-dynamics simulations were performed to model the effect of added salt ions on the liquid-liquid interface in a partially miscible system. Simulations of the interface between saturated phases of a model 1-hexanol + water system show a bilayer structure of 1-hexanol molecules at the interface with OH heads of the first layer directed into the water phase and the opposite orientation for the second layer. The alignment of the polar OH groups at the interface stabilizes a charge separation of sodium and chloride ions when salt is introduced into the aqueous phase, producing an electrical double layer. Chloride ions aggregate …

“We Navigated By Pure Understanding”: Bishop George T. Sevey's Account Of The 1912 Exodus From Mexico, Michael N. Landon Apr 2004

“We Navigated By Pure Understanding”: Bishop George T. Sevey's Account Of The 1912 Exodus From Mexico, Michael N. Landon

BYU Studies

During July and August 1912, thousands of Mormon colonists fled the turmoil of the Mexican Revolution (fig. 1). As bishop of the Colonia Chuichupa ward, George Sevey led his ward members out of war-torn Mexico and into the United States. The scene was not unfamiliar. During the nineteenth century, Latter-day Saints had fled from Missouri and Illinois, and thousands more had experienced the great exodus across the plains to the Salt Lake Valley. Such epic events enrich the heritage of Latter-day Saints, providing cultural meaning and shared identity forged by hardship and tragedy. Perhaps the effort to chronicle flight from …

Fast Registration Of Tabular Document Images Using The Fourier-Mellin Transform, Luke Alexander Daysh Hutchison Mar 2004

Fast Registration Of Tabular Document Images Using The Fourier-Mellin Transform, Luke Alexander Daysh Hutchison

Theses and Dissertations

Image registration, the process of finding the transformation that best maps one image to another, is an important tool in document image processing. Having properly-aligned microfilm images can help in manual and automated content extraction, zoning, and batch compression of images. An image registration algorithm is presented that quickly identifies the global affine transformation (rotation, scale, translation and/or shear) that maps one tabular document image to another, using the Fourier-Mellin Transform. Each component of the affine transform is recovered independantly from the others, dramatically reducing the parameter space of the problem, and improving upon standard Fourier-Mellin Image Registration (FMIR), which …

An Implementation Of A Drill And Practice System To Assist In The Teaching Of Basic Music Theory, Todd C. Wilson Mar 2004

An Implementation Of A Drill And Practice System To Assist In The Teaching Of Basic Music Theory, Todd C. Wilson

Theses and Dissertations

In order to help a group of introductory-level music students achieve a foundational understanding of music theory, a series of computer-based instructional modules were developed using a system called Technology-Assisted Language Learning (TALL). This system, though primarily intended to be used in developing natural language-based instruction, was designed to be flexible enough to handle a broad range of academic subjects. The design of the instruction was largely accomplished via formative evaluation, where student and expert reviews of prototypes played a significant role. Students reviewed three separate prototypes of the instruction, and experts in instructional design and evaluation were also asked …

Phylogenetic Systematics And Evolution Within The Family Scincidae, Alison Swindle Whiting Mar 2004

Phylogenetic Systematics And Evolution Within The Family Scincidae, Alison Swindle Whiting

Theses and Dissertations

Scincidae (skinks) comprise one of the largest families of lizards, and the more than 1300 species show great variation in body size and form, and are found worldwide in a diversity of habitats. The group presents many interesting questions ranging from the colonization of oceanic islands, to the evolution of limb loss, yet most of these and other questions remain understudied. The purpose of this dissertation is to use multiple mitochonidrial and nuclear DNA markers in connection with current cladistic methods to address evolutionary questions at many levels within Scincidae. In chapter one, a molecular phylogenetic study, based on six …

Perspectives Of Pro-Revivalism: The Christian History And The Great Awakening, Lisa Thurston Brown Mar 2004

Perspectives Of Pro-Revivalism: The Christian History And The Great Awakening, Lisa Thurston Brown

Theses and Dissertations

The Christian History was a pro-revivalist magazine printed in Boston from 1743-1745 during what is known as the Great Awakening. It contained accounts of revivalism written by pro-revivalist ministers from throughout the American colonies, England and Scotland. These ministers believed that the Holy Spirit was being poured out upon the land in a shower of grace, causing unprecedented numbers of people to convert to Christ. In The Christian History, pro-revivalist ministers expressed their support for the revivals and shared their experiences. Thus the magazine has typically been viewed as religious propaganda advocating a single, polemical viewpoint. However, in spite …

A Fish Survey Of The White River, Nevada, G. Gary Scoppettone, Peter H. Rissler, Sean Shea Feb 2004

A Fish Survey Of The White River, Nevada, G. Gary Scoppettone, Peter H. Rissler, Sean Shea

Western North American Naturalist

In spring and summer 1991 and 1992, we surveyed fishes of the White River system, Nye and White Pine Counties, Nevada, to determine the status of natives. There are 5 known native fishes to the White River: Lepidomeda albivallis (White River spinedace), Crenichthys baileyi albivallis (Preston White River springfish), Crenichthys baileyi thermophilus (Moorman White River springfish), Catostomus clarki intermedius (White River desert sucker), and Rhinichthys osculus ssp. (White River speckled dace). All 5 had declined in range. Lepidomeda albivallis had experienced the greatest decline, with less than 50 remaining, and these were restricted to a 70-m stream reach. Rhinichthys osculus …

Contribution To The Morphology And Descriptive Biology Of Caurinella Idahoensis (Ephemeroptera: Ephemerellidae), Luke M. Jacobus, W. P. Mccafferty Feb 2004

Contribution To The Morphology And Descriptive Biology Of Caurinella Idahoensis (Ephemeroptera: Ephemerellidae), Luke M. Jacobus, W. P. Mccafferty

Western North American Naturalist

Reared specimens from Bridge Creek, Idaho County, Idaho, provide the bases for the first descriptions of Caurinella idahoensis egg and alate stages and redescription of the larval stage. Larvae are distinguished from other Nearctic Ephemerellinae species by the distinctive posterolateral projections on abdominal segment 9. Male adults have a unique combination of characters associated with their genitalia. Larvae were associated with the colonial bluegreen alga Nostoc parmelioides in a clear, cold headwater stream. Several other Diptera, Ephemeroptera, Plecoptera, and Trichoptera also were found in cohabitation with C. idahoensis. Amorphous detritus appears to be a major component of the diet …

Conservation, Status, And Life History Of The Endangered White River Spinedace, Lepidomeda Albivallis (Cyprinidae), G. Gary Scoppettone, James E. Harvey, James Heinrich

Western North American Naturalist

Lepidomeda albivallis (White River spinedace), a fish species endemic to the White River, Nevada, appeared headed toward extinction. In 1991 only 1 population remained, and it comprised fewer than 50 individuals in a 70-m stream reach. We monitored population recruitment and distribution and studied life history and habitat use from 1993 through 1998. We determined that L. albivallis was not reproducing and was continuing to decline, and as an emergency measure we relocated the population (14 in spring 1995 and 6 in spring 1996) downstream 200 m to a secure habitat that we judged more favorable for reproduction. The relocated …

Coyote (Canis Latrans) Movements Relative To Cattle (Bos Taurus) Carcass Areas, Jan F. Kamler, Warren B. Ballard, Rickey L. Gilliland, Kevin Mote Feb 2004

Coyote (Canis Latrans) Movements Relative To Cattle (Bos Taurus) Carcass Areas, Jan F. Kamler, Warren B. Ballard, Rickey L. Gilliland, Kevin Mote

Western North American Naturalist

Use of 2 cattle carcass areas was determined for radio-collared coyotes (Canis latrans) in northwest Texas from January 1999 to January 2000. When 0–3 dead cattle were located at the carcass areas, resident and transient coyotes visited the carcass areas 4% and 8% of the time, respectively. However, when 30–35 dead cattle were located at 1 carcass area due to a disease epizootic, resident and transient coyotes had increased visitation rates of 19% and 63%, respectively. Resident coyotes traveled as far as 12.2 km from the center of their home ranges, suggesting that carcass areas influenced residents over …

Occurrence And Habitat Use Of Passage Neotropical Migrants In The Sonoran Desert, Paul C. Hardy, David J. Griffin, Amy J. Kuenzi, Michael L. Morrison Feb 2004

Occurrence And Habitat Use Of Passage Neotropical Migrants In The Sonoran Desert, Paul C. Hardy, David J. Griffin, Amy J. Kuenzi, Michael L. Morrison

Western North American Naturalist

Little is known about stopover habitat use by neotropical migratory birds in the deserts of North America. We determined distribution, abundance, and habitat associations of neotropical migrants during spring migration in the Sonoran Desert of southwestern Arizona along large washes that supported xeroriparian scrub vegetation. We detected 91 bird species during surveys, 50 (52%) of which were passage neotropical migrants. Although xeroriparian scrub covered less than 55% of the area surveyed, 97% of all detections of passage migrants were from this vegetation type. By calculating habitat breadth for each species, we classified 87% of passage migrants as xeroriparian specialists. Richness …

Species Diversity And Habitat Of Grassland Passerines During Grazing Of A Prescribe-Burned, Mixed-Grass Prairie, Robert F. Danley, Robert K. Murphy, Elizabeth M. Madden

Western North American Naturalist

No published data exist on responses of grassland passerines and their habitat to combined grazing and burning treatments in northern mixed-grass prairie. At Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota, we monitored breeding bird occurrence, abundance, and habitat during successive annual grazing treatments (1998–2000) on 5 prescribe-burned, mixed-grass prairie management units (range = 50–534 ha, each burned 3–6 times in the previous 10–20 years). All breeding passerine species characteristic of upland, northern mixed-grass prairie were common (>10% occurrence) during at least 1 of 3 years on burned and grazed units, except Chestnut-collared Longspur (Calcarius ornatus), …

Habitat Of Three Rare Species Of Small Mammals In Juniper Woodlands Of Southwestern Wyoming, Kevin M. Rompola, Stanley H. Anderson Feb 2004

Habitat Of Three Rare Species Of Small Mammals In Juniper Woodlands Of Southwestern Wyoming, Kevin M. Rompola, Stanley H. Anderson

Western North American Naturalist

Southwestern Wyoming constitutes the northern limit of the ranges of the cliff chipmunk (Tamias dorsalis), pinyon mouse (Peromyscus truei), and canyon mouse (P. crinitus). In addition to trying to determine their presence in the region, we wanted to identify habitat characteristics commonly used by each of these species. We used Sherman live-traps to sample 14 sites representing 2 distinct habitat types in 1998 and 1999: juniper-rocky slopes and juniper cliffs. Seventeen habitat characteristics were measured at capture locations for each species and compared with randomly located points. Best subsets multiple logistic regression was used …

Beavers Indirectly Enhance The Growth Of Russian Olive And Tamarisk Along Eastern Montana Rivers, Peter Lesica, Scott Miles Feb 2004

Beavers Indirectly Enhance The Growth Of Russian Olive And Tamarisk Along Eastern Montana Rivers, Peter Lesica, Scott Miles

Western North American Naturalist

Russian olive and tamarisk are introduced woody plants invading western North American riparian communities. Beavers can play an important role in structuring these communities by removing the dominant cottonwood trees. Our study explored the way in which beavers interact with cottonwood, Russian olive, and tamarisk along 4 rivers on the Great Plains of eastern Montana. We sampled cottonwood stands that supported populations of 1 or both exotic species, recording beaver damage and density in addition to size and age of cottonwood, Russian olive, and tamarisk. In stands where beaver had been present, they felled an average of 80% of cottonwood …
