Grand Canonical Monte Carlo And Modified Singlet Integral Equations For The Density Profile Of A Yukawa Fluid Near A Planar Wall, Douglas Henderson, Wilmer Olivares-Rivas, Leo Degreve, Jacqueline Quintana
Grand Canonical Monte Carlo And Modified Singlet Integral Equations For The Density Profile Of A Yukawa Fluid Near A Planar Wall, Douglas Henderson, Wilmer Olivares-Rivas, Leo Degreve, Jacqueline Quintana
Faculty Publications
Results for the density profile for Yukawa molecules near a hard wall and an exponential attractive wall are presented for Grand Canonical Monte Carlo (GCMC) simulations, for the singlet hypernetted chain (HNC) integral equation and for a modified version of the Lovett–Mou–Buff–Wertheim (LMBW-1) which uses the exact contact value theorem. The results of the standard singlet HNC are quite poor. If the LMBW equation is modified (but still using the bulk direct correlation function) the results at high temperature become reasonable. However, the results at low temperatures, close to the bulk coexistence curve, are only a partial improvement. The contact …
Signal Transduction Pathways In Volvox Carteri, Heide Girardin
Signal Transduction Pathways In Volvox Carteri, Heide Girardin
Honors Theses
The green alga Volvox carteri exhibits a virtual absence of protein synthesis in the dark, but begins synthesizing proteins necessary for growth and development almost immediately after exposure to the light. The regulation of protein synthesis in this system is known to be translational since extracts prepared in the dark have identical pools and quantities of mRNA as extracts prepared in the light (Kirk and Kirk, 1983). Exploration of the mechanism of translational regulation has led us to consider the importance of signal transduction pathways. By using a variety of commercially available drugs that affect specific components of known signaling …

Celluloid Blackness : Race, Modernity, And The Conflicted Roots Of American Cinema (1915-1939), Lincoln Farr
Honors Theses
Introduction: "The Problem of the Twentieth Century" In a full page interview in the New York Times on May 29, 1912, the Swiss psychiatrist Dr. Carl G. Jung told the American people, "It seems to me that you are about to discover yourselves. You have discovered everything else-all the land of this continent; all the resources, all the hidden things of nature."Jung used the interview to address the American people, at a moment which he somehow recognized as crucial in the development of human civilization. America, the "tragic" country which he struggled to comprehend, would soon become the harbinger of …

Chemistry & Biochemistry Publications
Organic dyes have found increasing use a s sensitizers in laser surgical procedures, due to their high optical absorbances. Little is known, however, about the nature of the degradation products formed when these dyes are irradiated with a laser. Previous work in our laboratories has shown that irradiation of polymeric and biological tissues with CO2 and Nd:YAG lasers produces a host of volatile and semivolatile by-products, some of which are known to be potential carcinogens. This work focuses on the identification of the chemical by-products formed by diode laser and Nd:YAG laser irradiation of indocyanine green (ICG) and carbon black …

Quantitative Analysis Of Microbial Growth In Selected Meats Before And After Spoilage Due To Change In Temperature, Richelle Beverly
Electronic Dissertations and Theses
Upton Sinclair wrote The Jungle over ninety years ago. This book exposed the failures of the United States meat packing industry which led to major modernization of the meat safety system. The beef and poultry industry make up about 66 percent of the total meat eaten by Americans. Due to many illnesses and deaths in recent years, the United States Department of Agriculture is announcing new measures to reduce harmful bacteria levels in products. Quality control and safety measures to protect consumers have been put in place by I • I the Food and Drug Administration. Consumers are warned of …
The Effects Of Hydrilla Infestation On Selected Wintering Waterfowl: Santee Copper Lake System, South Carolina, William Davis
The Effects Of Hydrilla Infestation On Selected Wintering Waterfowl: Santee Copper Lake System, South Carolina, William Davis
Masters Theses & Specialist Projects
Hydrilla is an exotic aquatic weed that was introduced into Florida in the 1950's. Since that time it has spread rapidly from lake to lake throughout the southeast and beyond. The Santee Cooper lake system in eastern South Carolina was infested with the weed in the early 1980's. Since that time lake managers have sought ways to eliminate the aquatic plant and have succeeded to a great extent through the use of sterile grass carp as a biological control agent. This paper, however, contains evidence to support the view that hydrilla is actually a beneficial habitat for many species on …

Wildfire Case Study: Butte City Fire, Southeastern Idaho, July 1, 1994, Bret W. Butler, Timothy D. Reynolds, United States Department Of Agriculture, Forest Service, Intermountain Research Station
All U.S. Government Documents (Utah Regional Depository)
The Butte City Fire occurred on July 1, 1994, west of Idaho Falls, ID. Ignited from a burning flat tire, the blaze was driven by high winds that caused it to cover over 20,500 acres in just over 6.5 hours. Sagebrush (Artemisia tridentata ssp. wyomingensis) is the principal shrub species of this high dese~t rangeland. With the absence of vegetation after the fire, erosion increased tremendously. Because the fire occurred on the Idaho National Engineering Laboratory, researchers were able to gather weather information from remote meteorological stations positioned on and around the site.

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard
Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard
Masters Theses & Specialist Projects
The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …

Coastal Circulations Driven By River Outflow, Shuliang Zhang
HCNSO Student Theses and Dissertations
Variable-density, 11/2- and 21/2- layer models are used to examine the behavior of plumes resulting from a fresher outflow of transport Mr and salinity Sr into a pre-existing oceanic layer of initial thickness H1 and salinity S1. It is found that the plumes exhibit a variety of features depending on conditions of the outflow, the situation of the ambient ocean, and external forcing. Perhaps the most interesting feature is that the plume can flow along the upstream (to the left of the river mouth, looking seaward in the northern hemisphere) coast …

Study On The Parasites Of Falcons In The United Arab Emirates, Mohammad Ismail M. A Sultan Al-Ulama
Theses
Sakers Falco cherrug, Gyrfalcons Falco rusticolus, Peregrines Falco peregrilllls, in addition to Hybrids (saker X gyrfalcon, or gyrfalcon X peregrine), were found to be the most popular species of falcons in United Arab Emirates (UAE).
The importance of falcons and falconry in Arabia was highlighted with a brief history of falconry in Arabia.
The study focused on the prevalence of intestinal parasites (coccidia, helminthes and nematodes) and blood parasites (Haemoproteus sp. and Leucocytozoon sp.) as well as ecto-parasites (Ticks and Mites) of these falcons, with discussion on the possible sources of infection in view of the …
Developmental Taxonomy And Distribution Of Paralarval Squid From The Florida Current, Carrie Leeonne Adams
Developmental Taxonomy And Distribution Of Paralarval Squid From The Florida Current, Carrie Leeonne Adams
Theses and Dissertations
Distribution patterns of paralarval squid across the continental shelf of Florida were examined based on five years of collections. Squid occurrence patterns were described in relation to coastal, intermediate, and Florida Current (Gulf Stream) water masses by comparing horizontal and vertical distribution patterns of squid species to physical-chemical distribution patterns Twenty-six squid taxa were collected in this study. Representative taxonomic descriptions and illustrations of all taxa were produced to serve as an identification aid for the paralarval squid from the Florida shelf. Patterns of species composition among stations were analyzed with cluster analysis based on four sampling approaches. Species distribution …
The Geomorphic Basis Of Colorado Squawfish Nursery Habitat In The Green River Near Ouray, Utah, Cynthia L. Rakowski
The Geomorphic Basis Of Colorado Squawfish Nursery Habitat In The Green River Near Ouray, Utah, Cynthia L. Rakowski
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nursery habitat availability is considered a bottleneck to successful recruitment of Colorado squawfish (Ptychocheilus Lucius). Detailed geomorphic studies were conducted in a 1.5-km reach to examine channel response to flows and the geomorphic setting of nursery habitats during a 2-year period. Videography was used to extend relationships in the 1.5-km reach to a longer 10-km reach.
Nursery habitat availability varied yearly with little persistence in location or geomorphic setting of individual habitats for the 2 years of this study. A small number of habitats provided most of the area of high-quality (i.e., deep) habitat, and most of the …
A Hydrogeochemical Study Of The Evolution Of The Headwaters Of The Bear River In The Uinta Mountains, Utah, Michael F. Leschin
A Hydrogeochemical Study Of The Evolution Of The Headwaters Of The Bear River In The Uinta Mountains, Utah, Michael F. Leschin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The headwaters of the Bear River in the Uinta Mountains of Utah provide a good setting in which to examine the influence of geological materials on stream chemistry. Ionic contributions to the stream-water from soils, vegetation, and the atmosphere generally are sparse enough that they do not mask the geologic contributions. Samples from 37 sites on the four major headwater streams and several minor tributaries were examined geochemically. Data derived from the samples allowed the construction of a hydrogeochemical weathering model specific to the study area. A significant feature of this model is that carbonic acid is the dominant chemical …

Geochemical, Petrologic, And Structural Characterization At Multiple Scales Of Deformation Associated With The Punchbowl Fault, Southern California, Steven E. Schulz
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Three traverses across the exhumed trace of the Punchbowl fault zone in the Pelona Schist, southern California, were examined at the millimeter to kilometer scales to determine the morphology, deformation mechanisms, and geochemistry of the fault zone in schistose rocks. The Pelona Schist is predominantly a quartz-albite-muscovite-actinolite schist with associated minor metabasalts. The Punchbowl fault zone, which is exhumed 2-4 km, has 44 km of right lateral slip, and is composed of a fault core enveloped by a damaged zone.
The fault core is a region of extreme slip localization that records most fault displacement. Deformation in the fault core …

Effects Of Flow Augmentation On Channel Morphology And Riparian Vegetation In The Upper Arkansas River Basin, Colorado, Dewitt S. Dominick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined historic change of riparian plant communities and fluvial geomorphic response of gravel-bedded streams and their floodplains to over 50 years of hydrologic disturbance. Four tributary basins of the Arkansas River were analyzed. Lake Creek, Clear Creek, and Cottonwood Creek are drainages similar in area, physiography, and vegetation composition. However, Lake Creek may receive an instantaneous discharge of approximately 28 m3sec-1 from the Twin Lakes tunnel, over three times the normal flow of the stream during spring runoff. By contrast, Clear Creek and Cottonwood Creek, nonaugmented streams, were used as controls to compare the historic and present …

Modelling Vegetation Cover Types Using Multiseasonal Remotely Sensed Data To Compare Ecotones At Multiple Spatial And Spectral Resolutions, Kimberly Patraw
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Army National Guard Bureau has implemented a cooperative project with Utah State University to help with the use, display, and evaluation of environmental data for maintaining land condition. Camp Grayling, Michigan, is comprised of deciduous and evergreen forest types. Use of remote sensing for classification has been limited in this region due to the difficulty of species-level classification using single-date remote-sensing techniques. Also, remote sensing has traditionally focused on mapping homogenous zones rather than vegetation boundaries, while one of the concerns for land managers is the nature of vegetation edges (ecotones).
This study analyzed each season and band from …

Post-Middle Miocene Geologic History Of The Tualatin Basin, Oregon With Hydrogeologic Implications, Doyle Coley Wilson
Dissertations and Theses
The geologic history and sedimentary till of the Tualatin Basin after Columbia River Basalt Group (CRBG) emplacement is assessed and related to groundwater characteristics. The 334 m deep HBD-1 core from the Hillsboro Airport, provides the primary information for sediment characterization and is supported by over 2400 well logs and cores, and four seismic lines. The sedimentary section above the 26 m thick paleosol on the CRBG in HBD-I is divided into two main groups: a 25 m thick section of Missoula flood sediments called the Willamette Silt overlies a 263 m thick finegrained sequence of fluvial Neogene sediments.

Identification Of Belowground Woody Structures Using Molecular Biomarkers, Benny R. Bobowski
Identification Of Belowground Woody Structures Using Molecular Biomarkers, Benny R. Bobowski
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Within the last two decades substantial progress has been made in understanding seed bank dynamics and the contribution of the soil seed bank to a post-disturbance plant community. There has been relatively little progress, however, in understanding perennial bud bank dynamics and the contribution of the soil bud bank to secondary succession. This lack of information is due primarily to the inability to reliably identify roots, rhizomes, and lignotubers that lie dormant beneath the soil surface. This scientific investigation, therefore, addressed the issue of identification of belowground woody structures.
The first objective was to develop a methodology that utilizes molecular …
