Two-Dimensional Fast Evanescent Wave Algorithm, W. C. Chew, L. (Lijun) J. Jiang, S. Velamparambil

Electrical and Computer Engineering Faculty Research & Creative Works

A new fast evanescent wave algorithm (FEWA) is introduced in the two-dimensional (2-D) case. It expands the Green's function into propagating waves and directional evanescent waves. Applying the evanescent wave correction technique, a procedure similar to the traditional MLFMA can be expedited. No buffer region is necessary anymore, and fewer translators are needed. Numerical examples are given to show the features of this method.

Hanford Radioactivity In Salmon Spawning Grounds, Government Accountability Project, Norm Buske

Government Accountability Project (GAP)

The public has expressed concern that radioactivity from Hanford’s wartime nuclear weapons production might contaminate salmon spawning grounds in the Columbia River. Salmon hatchlings (alevin) grow among the gravels in the riverbed, where they are susceptible to environmental stresses that include toxic chemicals and radioactivity. Some people worry that radioactivity from Hanford will damage the alevin genetically and slowly reduce the strength of the salmon stock.

In 2001, The RadioActivist Campaign (TRAC) found a radioactive fingerprint (europium-152) of old Hanford nuclear waste in 60% of sediments lying under the Hanford Reach and in 7 of 10 major salmon spawning areas. …

Use Old Christmas Trees To Provide Cover For Wildlife, Mitchell Diggs

University of Mississippi News

UNIVERSITY, Miss. -- Old Christmas trees -- Martha Stewart may have dozens of creative uses for them, but most folks just chuck the holiday centerpiece on the curb with the other remnants of cheer. Instead, consider using it to help fish and other wildlife, suggests Dr. Stephen Brewer, assistant professor of biology at The University of Mississippi (UM). Using old trees to construct fish shelters in lakes and reservoirs is one option that has gained favor with conservation officials.

Finite Element Analysis Of Yield Functions Of Kelvin Foams With Open Cells, Beiqing Huang

Engineering

Proper design of foams requires an understanding of the response of the materials to stress. This thesis, based on finite element analysis, provides numerical solutions in modeling the yield behavior of Kelvin foams. The FEA model, representing a complicated unit cell, was calculated and meshed. C++ programs were designed and implemented to generate meshes for unit cells. Finite element analyses were performed for many cases. Multiple methods were employed for the determination of yield points which form yield surfaces. Comparisons between several results have been made. Our FEA results, Zhang's function and Gibson's theory show good agreements except some differences …

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas

Faculty Publications

To facilitate detection of glycoprotein K (gK) specified by herpes simplex virus, a 12-amino-acid epitope tag was inserted within gK domain III. Recombinant virus gKprotC-DIII, expressing the tagged gK, was isolated. This virus formed wild-type plaques and replicated as efficiently as the wild-type KOS virus in Vero cells. Anti-protein C MAb detected high-mannose and Golgi complex-dependent glycosylated gK within cells as well as on purified virions. The gK-null virus ΔgK (gK-/-) entered Vero cells substantially more slowly than the wild-type KOS (gK+/+), while ΔgK virus grown in complementing VK302 cells (gK-/+) entered with entry kinetics similar to those of the …

The Origin And Composition Of Aerosols In The Alaskan Airshed, Walter James Wilcox

Chemistry and Biochemistry

Since the Alaskan airshed north of the Alaska Range receives a substantial portion of its anthropogenic aerosol and gaseous pollutants through long-range transport, Alaskan air quality is influenced to an unusually high degree by the political and economic events of other countries. An understanding of the political and economic forces at work in the various circumpolar nations is key to an understanding of the observed decline in Arctic haze, the present state of Arctic air pollution, and likely future developments. It is shown in this thesis that Arctic haze has declined in Interior Alaska over the last decade and a …

Understanding The Lived Experience Of Racist Hate Speech On American University Campuses, Jonathan Andre Matusitz

Communication

This research employs narrative methodology in order to understand the lived experience of students who have experienced racist racist hate speech on American university campuses. Thematic analysis of in-depth, conversational interview capta (Kvale, 1996) was used to find commonalities in co-researchers' experiences. The literature review includes a contextual and historical section on racism, and a detailed, standard definition of racist hate speech. Emergent themes from these narrative interviews were found in regard to victims' experiences of racist hate speech on American university campuses. Those themes are discussed in the order of the co-researchers' experience: (1) indignation and anger, (2) stereotyping, …

Search For Gluinos And Squarks Using Like-Sign Dileptons In Pp̅ Collisions At √S= 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We present results of the first search for like-sign dilepton (e^±e^{±, e± μ±, μ± μ±) events associated with multijets and large missing energy using 106 pb-1 of data in pp̅ collisions at √s= 1.8 TeV collected during 1992–1995 by the CDF experiment. Finding no events that pass our selection, we examine pair production of gluinos (g̃) and squarks (q̃) in a constrained framework of the minimal supersymmetric standard model. At tanβ =2 and μ = -800 GeV/c2, we set 95% confidence …}

Spatial Distribution And Temporal Variability Of Lithogenic Particles In First-Year Sea Ice And Conditions Responsible For Particle Entrainment, Aaron Patrick Stierle

Geosciences

Processes controlling the spatial and temporal variability of sea ice sediment inclusions in the shallow-marine environment of Elson Lagoon near Barrow, Alaska, were studied by modeling the potential for sediment resuspension during the 1998, 1999 and 2000 fall freeze-up events and examining sea ice cores from the post-freeze-up ice cover. Resuspension potential was controlled spatially by the local bathymetry and interannually by wind speed and fetch. Increases in resuspension potential corresponded to greater sea ice sediment content. Sediments occurred exclusively as aggregates confined to brine inclusions in the ice and exhibited a tendency toward a clustered spatial distribution, because of …

A Window To The Past: Macrofossil Remains From An 18,000 Year-Old Buried Surface, Seward Peninsula, Alaska, Victoria Goetcheus Wolf

Geosciences

Macrofossil remains and pollen from an 18,000 year old buried surface from the northern Seward Peninsula enable a reconstruction of the full-glacial environment of an upland portion of the Bering Land Bridge. The buried surface represents a dry meadow and herb-rich tundra. Prostrate shrubs were rare on the landscape, but abundant locally. A large and diverse insect fauna populated the surface, preying on the plants and each other. Small mammals and their predators lived on the surface. Large mammals, such as caribou and bison, were present as well. The productivity of the surface was maintained by a continual influx of …

Herbivore-Mediated Effects On Ecosystem Processes In A Near-Arctic Salt Marsh, Brian Thomas Person

Biological Sciences

Herbivores influence, and often regulate energy flow. I investigated interactions between herbivory and the foods on which geese rely while nesting and rearing their broods on the Yukon-Kuskokwim Delta in southwestern Alaska. In a captive Cackling Canada gosling (Branta Canadensis minima) experiment I decoupled the effects of seasonal declines in forage quality and availability on gosling development. An 11% decline in forage quality translated to goslings that were structurally smaller and 100 g lighter at 31 days of age. Forage availability had similar effects on gosling size, and the combined magnitude of these effects are similar to those observed in …

Role Of Wetlands And Endogenous Factors On Incubation Behavior Of Nesting Spectacled Eiders On The Yukon-Kuskokwim Delta, Alaska, William Todd O'Connell

Biological Sciences

Patterns of nest attendance in ducks vary with endogenous and environmental factors. We examined variation in nest attendance of spectacled eiders on the Yukon-Kuskokwim Delta, Alaska, during 1997-1998. We also examined spatial and temporal variation in wetland characteristics and potential foods available to nesting spectacled eiders. Time spent foraging was greater when spectacled eiders traveled farther to feed, and nest attendance was lower when food was more abundant, suggesting that females made tradeoffs between foraging and energetic requirements of nesting in response to food abundance and wetland conditions. Wetlands were dynamic, and food abundance varied with pond depth and total …

Trace Mineral Reserves For Reproduction And Development In Muskoxen, Emmajean Pearl Rombach

Biological Sciences

In muskoxen (Ovibos moschatus), trace minerals required for reproduction and development are unknown. I described use of copper in pregnant muskoxen and concurrent accumulation of copper in fetuses. Utilization of copper was examined in neonates during early development and importance of milk as a source of copper was assessed. Additionally, I examined the effect of maternal copper supplementation during gestation on copper reserves acquired in-utero, and during lactation on mineral status of milk. During gestation, the fetus must acquire reserves of copper adequate to support early neonatal development because milk is a poor source of copper. The transition from milk …

Ultraviolet Light-Emitting Diodes At 340 Nm Using Quaternary Alingan Multiple Quantum Wells, V. Adivarahan, A. Chitnis, J. P. Zhang, M. Shatalov, J. W. Yang, Grigory Simin, M. Asif Khan, R. Gaska, M. S. Shur

Faculty Publications

An ultraviolet light-emitting diode with peak emission wavelength at 340 nm is reported. The active layers of the device were comprised of quaternary AlInGaN/AlInGaN multiple quantum wells, which were deposited over sapphire substrates using a pulsed atomic-layer epitaxy process that allows precise control of the composition and thickness. A comparative study of devices over sapphire and SiC substrates was done to determine the influence of the epilayer design on the performance parameters and the role of substrate absorption.

Calving Ground Habitat Selection: Teshekpuk Lake And Western Arctic Caribou Herds, Rebecca A. Kelleyhouse

Biological Sciences

Barren-ground caribou (Rangifer tarandus granti) exhibit relative fidelity to calving grounds each spring. The Western Arctic Herd (WAH) and Teshekpuk Lake Herd (TLH) calve separately on Alaska's north slope, each selective of the dominant vegetation type. The WAH consumed mostly sedges, though the TLH diet varied. Despite differing snow conditions between the calving grounds, both herds were selective of the lowest snow cover class. Rugged terrain was avoided by both herds. While the TLH selected a high rate of increase in biomass, the WAH selected high biomass at calving and at peak lactation. Climate trends (1985-2001) were variable. There was …

Abundance And Ecology Of Martens (Martes Americana) In Interior Alaska, Brad Shults

Biological Sciences

I studied marten (Martes americana) abundance and ecology in the Yukon-Charley Rivers National Preserve during 1991-1993. Using a multiple sample, mark-recapture estimator, I estimated marten densities to be 0.69, 0.41, and 0.45 martens/km² during each August for 1991-1993, respectively. Density estimates were derived with the boundary-strip method to address the edge effect inherent in live-trapping studies. During the study, marten density declined 43% between 1991 and 1992 and remained low during 1993. I hypothesize that a decline in primary prey (i.e., microtine rodents) and increased environmental stress (i.e., cold temperatures and snow cover) contributed significantly to the decline in marten …

Cross-Seasonal Effects On Reproductive Performance Of Pacific Black Brant, Jason Lee Schamber

Biological Sciences

We used re-sightings of Pacific Black Brant from San Quintin Bay, Ojo de Lieber Lagoon, and San Ignacio Lagoon, Baja California and Boundary Bay, British Columbia, to examine winter population structure, variation in structural size and the importance of winter location to individual reproductive performance at the Tutakoke River colony. Sexes of adults and juveniles were distributed equally among winter locations. Adult structural size and mean age were similar among winter locations. A higher proportion of juveniles over-wintered in San Quinton Bay and Ojo de Liebre Lagoon. Individuals wintering at Ojo de Liebre and San Ignacio lagoons were less likely …

An Economic Appraisal Of Hole Cleaning Using Hydraulic Horsepower And Jet Impact Force, James Alfred Wright

Engineering

In today's competitive business environment, reducing operating cost means dollars to the bottom line. One way that a drilling company can reduce operating cost is by optimizing energy use at the mud pumps. The mud pumps are massive pieces of equipment that are the backbone of the cutting's removal system. Optimizing the hydraulics program is one way to reduce mud pump operating cost. Big hydraulics play an important role in the drilling process. The beneficial action of the fluid's cleaning the bottom hole and the bit teeth, and carrying particles into the annulus is well-established. A variety of hydraulic optimization …

Laser Intensity Scaling Through Stimulated Scattering In Optical Fibers, Timothy H. Russell

Theses and Dissertations

The influence of stimulated scattering on laser intensity in fiber optic waveguides is examined. Stimulated Brillouin scattering (SBS) in long, multimode optical waveguides is found to generate a Stokes beam that propagates in the fiber LP01 mode. Additionally, the same process is found to combine multiple laser beams into a single spatially coherent source. Limitations in beam cleanup and combining are also investigated to identify ways to overcome them. The last portion of the dissertation theoretically examines suppression of stimulated Raman scattering in fibers to eliminate the restriction this imposes on the power of a fiber laser or amplifier. The …
