Manure Use Planning: An Evaluation Of A Producer Training Program, Charles S. Wortmann, Richard K. Koelsch, Charles A. Shapiro, Richard L. Deloughery, David D. Tarkalson

Department of Agricultural and Biological Systems Engineering: Faculty Publications

A training program for producers in manure use planning was evaluated. The potential for runoff nutrient loss to surface water can reduced and the value of manure increased through better planning of manure use. Training was conducted throughout Nebraska in 2002 and 2003. Livestock producers who attended evaluated the event at the end of the last class. The need for and impact of the training was greater for continuing operational and maintenance skills of manure utilization that are regularly needed for strategic planning skills. We recommend that training focus primarily on operational and maintenance skills.

Farnesol Concentrations Required To Block Germ Tube Formation In Candida Albicans In The Presence And Absence Of Serum, Daniel D. Mosel, Raluca Dumitru, Jacob M. Hornby, Audrey L. Atkin, Kenneth W. Nickerson

Papers in Microbiology

Concentrations of (E,E)-farnesol needed to inhibit germ tube formation were determined for Candida albicans strains A72 and SC5314 by using six different conditions known to trigger germination. For defined media, 1 to 2 μM farnesol was sufficient. However, with serum at 2 to 20%, up to 250 μM farnesol was required. Farnesol blocked germ tube formation but did not block elongation of existing germ tubes.

Effects Of Human Granulocyte-Colony Stimulating Factor On Fracture Healing In Rats, Murat Bozlar, Bahadir Aslan, Aydiner Kalaci, Lutfu Baktiroglu, Ahmet N. Yanat, Arzu Tasci

Saudi Medical Journal

OBJECTIVE: Granulocyte colony stimulation factor (G-CSF) is generally used to prevent and cure the neutropenia associated with chemotherapy and bone marrow transplantation. In addition to its effects on neutrophil function, G-CSF was found to have the characteristic of modulating the cytokines in the inflammatory response. Then, the question to answer is whether it has any effect on fracture healing and to what extent? In this study, we test the effects of G-CSF on the healing of tibia fracture in a rat model. METHODS: This study was performed at Harran University, Sanliurfa, Turkey between July 2003 and August 2004. Twenty female, …

Spread Of An Exotic Fish-Gill Trematode: A Far-Reaching And Complex Problem, Andrew J. Mitchell, Robin M. Overstreet, Andrew E. Goodwin, Thomas M. Brandt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Centrocestus formosanus, the gill trematode, has caused serious losses among fish raised by tropical fish producers since the early 1980s and is believed to be harmful to wild fish populations, including the federally listed endangered fountain darter (Etheostoma fonticola), in the Comal River near San Marcos, Texas. The parasite appears to infect in many fishes from Hawaii, Florida, Texas, and Utah. The gill trematode has a complex life cycle involving definitive hosts (aquatic birds and occasionally some mammals) and intermediate hosts (aquatic snails and several fish species). In the United States, the green heron (Butorides virescens …

A Bioarchaeological Investigation Of Two Unmarked Graveyards In Bridgetown, Barbados, Christopher Crain

Masters Theses

In 1996 and 1999 two previously unknown graveyards were discovered in separate sections of Bridgetown, Barbados. Emergency excavations of the sites recovered the skeletal material of at least thirty-two (MNI=32) individuals as well as a number of grave goods. While the artifacts were from the historical period there was continuing speculation as to the ancestry of the individuals interred within these graveyards. During the summer of 2004 the first preliminary osteological analysis of the skeletal material was conducted to identify the biological characteristics, including the ancestral affiliation, of these individuals. The analysis determined that the individuals interred at these sites …

Design, Synthesis And Characterization Of Nanosensors For Nerve Gas Agents, Thushara Gunasinghe

Masters Theses

This research is focused on the design synthesis and characterization of nanosensors to detect the nerve gas agents such as sarin at very low concentration levels (parts per billion and lower) which is very important to combat terrorism. Nanosensors constructed by the bottom up approach could provide the low sensitivity levels and high selectivity required for nerve gas detection. The sensing mechanism exploits the inherent properties of nanomaterials and signal amplification by signal transduction. The components of a nanoparticle-fluorescent monomer-nanomolecule-receptor (NMNR) sensor have been designed, synthesized, and characterized successfully. Interaction of the components of NMNR sensor with a model nerve …

Molecular Serotyping Of Escherichia Coli O26:H11, Lisa M. Durso, James L. Bono, James E. Keen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Serotyping is the foundation of pathogenic E. coli diagnostics; however, few laboratories have this capacity. We developed a molecular serotyping protocol that targets, genetically, the same somatic and flagellar antigens of E. coli O26:H11 used in traditional serotyping. It correctly serotypes strains untypeable by traditional methods, affording primary laboratories serotyping capabilities.

At The Whim Of The State: Neoliberalism And Nongovernmental Organizations In Guerrero, Mexico, William Yaworsky

Anthropology Faculty Publications

This paper examines the relationship between the Secretaría de Desarrollo Social (SEDESOL) and nongovernmental organizations (NGOs) in the Chilapa region of Guerrero, Mexico. I argue that the Mexican state via SEDESOL has effectively harnessed NGOs to perform as regional pillars of neoliberal reform initiatives. The intimacy of this relationship raises serious questions for those who see NGOs performing as vehicles for furthering local or regional "autonomy." Instead, I argue that regional NGOs are key role players in the deepening incorporation of communities into the global industrial economy.

Este artículo examina las relaciones entre la Secretaría de Desarrollo Social (SEDESOL) y …

"Sibling Species, Advertisement Calls, And Reproductive Isolation In Frogs Of The Leptodactylus Pentadactylus Species Cluster (Amphibia, Leptodactylidae), W. Ronald Heyer, Rafael O. De Sá, A. Rettig

Biology Faculty Publications

A recent re-evaluation of morphological and advertisement call variation in the large species of frogs of the Leptodactylus pentadactylus cluster discovered more examples of sibling species as defined by Ernst Mayr in his influential book Animal Species and Evolution. All previously documented instances of sibling species in frogs demonstrated advertisement call differentiation consistent with the calls serving as pre-mating isolating mechanisms. However, we find one instance of two species with nondistinguishable adult morphologies as well as nondistinguishable advertisement calls. Presumably, the new instances of sibling species reflect retention of ancestral adult morphologies and advertisement calls. Larval and habitat differentiation appear …

Heparin Stimulates Staphylococcus Aureus Biofilm Formation, Robert M. Q. Shanks, Niles P. Donegan, Martha L. Graber, Sarah E. Buckingham, Michael Zegans, Ambrose Cheung, George A. O'Toole

Dartmouth Scholarship

Heparin, known for its anticoagulant activity, is commonly used in catheter locks. Staphylococcus aureus, a versatile human and animal pathogen, is commonly associated with catheter-related bloodstream infections and has evolved a number of mechanisms through which it adheres to biotic and abiotic surfaces. We demonstrate that heparin increased biofilm formation by several S. aureus strains. Surface coverage and the kinetics of biofilm formation were stimulated, but primary attachment to the surface was not affected. Heparin increased S. aureus cell-cell interactions in a protein synthesis-dependent manner. The addition of heparin rescued biofilm formation of hla, ica, and sarA …

Sexuality And The "System Of Liberty": Comment On Stolzenberg, William A. Galston

San Diego Law Review

Marriage and liberal democracy are forms of ordered liberty, one standing between sexual license and ascetics, and the other standing between anarchy and oppression. The relationship between liberal democracy and sexual liberty can be framed using four strategies devised by the liberal democratic project to limit the scope of personal freedom. This article places Stolzenberg's theory of love and liberty within the fourth strategy, which places limits on individual conduct through personal development and perfection. The author concludes that Stolzenberg is too bold for resting ordered sexual liberty on love, and suggests that the ultimate test for any form of …

Who's Afraid Of Polygamous Marriage? Lessons For Same-Sex Marriage Advocacy From The History Of Polygamy, Cheshire Calhoun

San Diego Law Review

Attention to polygamy can strengthen the case for same-sex marriage. Both the historical debate on polygamy and the current debate on same-sex marriage concentrate on finding the best social response for the failure of conventional marriage to serve its purpose. The argument for traditional marriage conflicts with the Judeo-Christian tradition and a liberal democracy. Contrary to traditionalist arguments, polygamy and pluralistic relationships are a part of the Judeo-Christian tradition. Additionally, a liberal democracy is designed to protect an individual?s right to pursue a pluralistic way of life. Under a liberal theory, the state should remain neutral and allow individuals to …

Microfocal X-Ray Computed Tomography Post-Processing Operations For Optimizing Reconstruction Volumes Of Stented Arteries During 3d Computational Fluid Dynamics Modeling, John F. Ladisa, Lars E. Olson, Kristina M. Ropella, Robert C. Molthen, Steven Thomas Haworth, Judy R. Kersten, David C. Warltier, Paul S. Pagel

Biomedical Engineering Faculty Research and Publications

Restenosis caused by neointimal hyperplasia (NH) remains an important clinical problem after stent implantation. Restenosis varies with stent geometry, and idealized computational fluid dynamics (CFD) models have indicated that geometric properties of the implanted stent may differentially influence NH. However, 3D studies capturing the in vivo flow domain within stented vessels have not been conducted at a resolution sufficient to detect subtle alterations in vascular geometry caused by the stent and the subsequent temporal development of NH. We present the details and limitations of a series of post-processing operations used in conjunction with microfocal X-ray CT imaging and reconstruction to …

Ascidians Of South Padre Island, Texas, With A Key To Species, Gretchen Lambert, Zen Faulkes, Charles C. Lambert, Virginia L. Scofield

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The ascidians of South Padre Island, Texas were surveyed in August 2004. Because the subtidal area is limited to soft sediments, the survey was restricted to marina floats and pilings, harbor buoys, boat hulls and other artificial substrates which offer suitable attachment surfaces for ascidians. Fifteen species were documented, with multiple species representing each of the three orders of ascidians. None of the species found in this survey are native, suggesting they were all introduced through boat traffic. About half the species were found in a reproductive state, however, indicating that they have established local breeding populations.

Gradient And Recurrence Analyses Of Four Marine Zones In The Glenshaw Formation (Upper Pennsylvanian, Appalachian Basin), Joseph G. Lebold

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Upper Pennsylvanian Glenshaw Formation contains a series of marine zones that were deposited on the detrital slope of the Appalachian highlands during the last major transgressions from the Midcontinent Sea in the Paleozoic of eastern North America. These marine zones contain distinctive fossil assemblages characterized as biofacies that inhabited a variety of shallow marine environments.;The first chapter of this paper focuses on the Ames marine zone sampled along a northwest-southeast transect across the Appalachian Basin. The Ames marine zone was deposited during the most extensive marine transgression of the Pennsylvanian in this region. Gradient analysis of the proportional abundance …

Reservoir Characterization Using Intelligent Seismic Inversion, F. Emre Artun

Graduate Theses, Dissertations, and Problem Reports (ETD)

Integrating different types of data having different scales is the major challenge in reservoir characterization studies. Seismic data is among those different types of data, which is usually used by geoscientists for structural mapping of the subsurface and making interpretations of the reservoir's facies distribution. Yet, it has been a common aim of geoscientists to incorporate seismic data in high-resolution reservoir description through a process called seismic inversion.;In this study, an intelligent seismic inversion methodology is presented to achieve a desirable correlation between relatively low-frequency seismic signals, and the much higher frequency wireline-log data. Vertical seismic profile (VSP) is used …

Does Peripheral Concentration Of Progesterone Affect Ovulation And Lambing Rates In Barbados Blackbelly Ewes?, Ezra Devonish

Graduate Theses, Dissertations, and Problem Reports (ETD)

The hypothesis that concentration of progesterone influences number of follicles that mature during estrus, and thus ovulation rate, was tested in cycling ewes. Ewes were assigned at random to three treatments, and bred at estrus after treatment. Ewes in low (LP) and high (HP) groups received exogenous progesterone from day 4 to 14; control ewes (MP) were untreated. The LP ewes were given PGF2alpha on day 6 to regress corpora lutea (CL). Numbers of follicles and CL were observed by transrectal ultrasonography. Fewer follicles disappeared at estrus in ewes on HP than in MP or LP. Ewes on LP had …

Trout Movement And Habitat Use In The Upper Shavers Fork Of The Cheat River, West Virginia, Jeff Lee Hansbarger

Graduate Theses, Dissertations, and Problem Reports (ETD)

I quantified brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta) movement and habitat use in a central Appalachian watershed, the upper Shavers Fork of the Cheat River over three seasons (spring/summer 2000-01, fall 2000) with telemetry. The objectives of my study were to: (1) quantify trout habitat use among seasons, and between the mainstem and Rocky Run (a major tributary), (2) quantify the effect of temperature extremes on habitat use by brook trout, (3) quantify trout movement among seasons and between the mainstem and Rocky Run, and (4) relate movement to variations in stream flow, water temperature, and access …

Fish Response To Discharge Events From A Power Plant Cooling Reservoir In A River Affected By Acid Mine Drainage And Thermal Influences, Cara Chowning Hoar

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the summer, a discharge from a power plant cooling reservoir (Mount Storm Lake) located on the Stony River can result in large increases in discharge and temperature. Further, the Stony River is affected by mining-impacted tributaries, which degrade water quality. To study the impact of reservoir discharges upon fish populations we evaluated community composition and smallmouth bass (Micropterus dolomieu) movement along a temperature gradient and relative to the mining-impacted tributaries. The fish community did not differ with discharge events, but community structure varied with mining-impacted inputs. Smallmouth bass avoided areas associated with mining-influenced inputs. Thermal increases associated with reservoir …

Prediction Of Forage Intake And Production Of Steers In A Winter Forage System, Taryn Romanczak

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently there are no means to accurately predict intake in grazing animals. Two experiments were conducted to determine and validate the use of intake markers in grazing ruminants as well as to compare performance of steers in winter forage systems. Six Angus-Hereford steers were halter and fecal harness broke. Entities commonly found in forages and used as markers were evaluated. Experiment 1 was conducted during the summer 2004, at the West Virginia University Livestock Farm, using animals in a confined area. Steers were fed timothy or orchardgrass hay chopped to fine or coarse lengths. Experiment 2 was conducted at the …

Response Of Clonal Genotypes Of Juncus Effusus L. To Different Environmental Regimes, Daniel Benjamin Stover

Graduate Theses, Dissertations, and Problem Reports (ETD)

A genetic tradeoff is hypothesized between resource use efficiency (RUE) and resource acquisition rate (RAR) in that it is impossible for selection to maximize both traits. In low-resource environments, RUE is expected to be favored while in high-resource environments RAR will be maximized. Growth rates and allocations of reciprocally transplanted clonal genotypes of J. effusus from differing nitrogen and elevation sites were examined. High-nitrogen populations outperformed their low-nitrogen counterparts, which were more nitrogen efficient. Plants originating from high-elevation sites grew larger irrespective of transplant environment. Elevation appears to be the dominant factor on biomass, nutrient allocation and growth at high …

The Role Of Reinforcement Rate On Fluency, Vennessa L. Walker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Building skills to high rates and accuracy has been purported to result in fluency, a set of behavioral outcomes identified as retention, endurance, application, problem solving, and stability (REAPS). These outcomes require that the skills persist under changing environmental conditions, and may be conceptualized as examples of resistance to change. As such reinforcement rate should be the critical factor. To test this conceptualization twelve subjects were trained on 5 algebra skills to specified rate and accuracy criteria. Feedback consisting of points, knowledge of results, and corrective feedback was delivered either every 1 or 5 minutes. Stability, application, and problem-solving were …

A Comparison Of The Growth And Asexual Reproduction By Cryphonectria Parasitica Isolates Infected With Hypoviruses Via Anastomosis And Transfection, Jenise M. Bauman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transfection is an alternative laboratory method of hypovirus transmission that can be used to create hypovirulent strains. Results from a preliminary study at West Virginia University in 1998-99 indicated that recovery of hypovirulent isolates was similar between CHV1-infected anastomosed and transfected isolates. The objective of this research was to compare the two hypovirus acquisition methods in three experiments. The first study confirmed the performance of anastomosed and transfected isolates tested in a 1998-99 field study. In addition to the isolates previously evaluated, a third set of isolates containing CHV3-County Line was included. The size of cankers and the reisolation of …
