Photochemical Transformations Of Riverine Dissolved Organic Matter: Effects On Estuarine Bacterial Metabolism And Nutrient Demand, Erik M. Smith, Ronald Benner

Faculty Publications

By experimentally simulating the exposure of terrigenous dissolved organic matter (DOM) to sunlight during the mixing of river water and seawater in an estuary (St. Helena Sound, South Carolina), this study examined how photochemical alterations may affect both the magnitude and fate of DOM utilization by estuarine bacteria. In a series of experiments performed with water samples collected from 3 blackwater rivers draining into an estuary of the South Atlantic Bight (USA), exposure to light resulted in significant decreases in dissolved organic carbon (DOC) concentration and DOM absorption at 350 nm relative to dark controls. When these water samples were …

Cloning, Expression, And Sequence Analysis Of Camelysin, A Zinc Metalloprotease From Bacillus Anthracis And B. Cereus, Andrew Ross Myers

USF Tampa Graduate Theses and Dissertations

Bacillus anthracis and B. cereus are well known etiological agents, which cause disease in healthy and immunocompromised individuals. Considering the abundance and lethality of these organisms it is imperative that research is performed to identify and analyze new factors that may contribute to their pathogenicity. Camelysin is a membrane bound, zinc metalloprotease isolated from B. cereus. Assays performed on purified camelysin demonstrate that the protease exhibits fibrinolytic, collagenolytic, and actin degradation activity, any of which can contribute to the organisms ability to invade host tissues and cause damage. Considering the putative role of camelysin in pathogenicity, it would be …

The Effects Of Labyrinthula Sp. Infection, Salinity, And Light On The Production Of Phenolic Compounds In Thalassia Testudinum, Jennifer M. Sneed

USF Tampa Graduate Theses and Dissertations

In the fall of 1987, several areas of Florida Bay were severely affected by the sudden die-off of the seagrass Thalassia testudinum Banks ex Konig (turtle grass). Although the cause is still unknown, several factors were suggested as influencing the on-set of the die-off event including increased salinity, light stress due to self-shading, and disease. Blades of seagrass plants found in the area of die-off were infected by Labyrinthula sp, a pathogenic protist. A similar die-off occurred in another species of seagrass, Zostera marina, in the 1930s that was attributed to the pathogenic protist, Labyrinthula zosterae. Zostera …

Dose Time Response Modeling Of Neurobehavioral Screening Data: Application Of Physiologically Relevant Parameters To Allow For Dose Dependent Time Of Peak Effects, Michael Raymond Wessel

USF Tampa Graduate Theses and Dissertations

In collaboration with the United States Environmental Protection Agency (USEPA), the University of South Florida Health Risk Methodology Group has developed dose-time-response models to characterize neurobehavioral response to chemical exposure. The application of dose-time-response models to neurobehavioral screening tests on laboratory animals allows for benchmark dose estimation to establish exposure limits in environmental risk assessment. This thesis has advanced dose-time-response modeling by generalizing a published toxico diffusion model to allow for dose dependent time of peak effects. To accomplish this, a biphasic model was developed which adopted the effect compartment model paradigm used in pharmacokinetics/pharmacodynamics to estimate a distributional rate …

Reconstructing Writer Identities, Student Identities, Teacher Identities, And Gender Identities: Chinese Graduate Students In America, Peiling Zhao

USF Tampa Graduate Theses and Dissertations

The increasing presence of Chinese international graduate students in American higher education has mandated a closer examination of their multifaceted lives against stereotypes that hinder their efforts to find, transform, or assert their identities in the dominant discourses of American academia and culture.

Cross cultural studies of Chinese international students tend to reinforce stereotypes of their writer identities, learner identities, and teacher identities. Examining these various identities discloses dichotomies that read Chinese students’ traits and behaviors as handicaps and thus characterize them as “abnormal” in relation to the “normal” traits and behaviors of Chinese students’ Western counterparts. Whereas Western student …

Hard-Sphere Radial Distribution Function Again, Andrij Trokhymchuk, Douglas Henderson, Ivo Nezbeda, Jan Jirsak

Faculty Publications

A theoretically based closed-form analytical equation for the radial distribution function, g(r), of a fluid of hard spheres is presented and used to obtain an accurate analytic representation. The method makes use of an analytic expression for the short- and long-range behaviors of g(r), both obtained from the Percus-Yevick equation, in combination with the thermodynamic consistency constraint. Physical arguments then leave only three parameters in the equation of g(r) that are to be solved numerically, whereas all remaining ones are taken from the analytical solution of the Percus-Yevick equation.

Modeling Water And Sediment Trapping By Vegetated Filters Using Vfsmod: Comparing Methods For Estimating Infiltration Parameters, Amanda Fox, Dean E. Eisenhauer, Mike Dosskey

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Vegetated filters (buffers) are used to intercept overland runoff and reduce sediment and other contaminant loads to streams (Dosskey, 2001). Filters function by reducing runoff velocity and volume, thus enhancing sedimentation and infiltration. lnfiltration is the main mechanism for soluble contaminant removal, but it also plays a role in suspended particle removal. By decreasing the discharge and velocity of overland flow, infiltration causes a decrease in sediment transport capacity, and thus sedimentation is enhanced.

Although the impact of infiltration on soluble and suspended contaminant removal has not been directly documented, many researchers suggest infiltration plays a significant role (Table 1). …

Integrating Animal Feeding Strategies Into Cnmp Processes: Role Of Updated Asae Standard D384.2, Richard K. Koelsch, W. Powers, A. L. Sutton

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

This paper introduces the new ASAE Standard D384.2, Manure Production and Characteristics. This new standard provides an equation-based approach that integrates dry matter and nutrient intake as well as animal performance into the final estimate of total solids, nitrogen, and phosphorus excretion for seven livestock and poultry species. The manure excretion estimates of the new standard are compared with the past ASAE standard as well as other commonly used reference values for three specie groups. Significant differences in excretion are common with the new standard compared to past standards. The paper also details examples of how common industry variations in …

Managing Phosphorus In Beef Feeding Operations, William F. Kissinger, Richard K. Koelsch, Galen E. Erickson, Terry J. Klopfenstein

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

A commercial feedlot study was conducted to determine manure nutrient flow in six feedlots representing 6,366 cattle. On average, cattle involved in this summary were yearlings (BW = 353 kg) and gained 183 kg over 123 d. It was calculated that 11.5% of the feed nitrogen and 16.9% of the feed phosphorus was retained by the animal with the remaining nutrients excreted. On average, 25.6 kg of N and 4.1 kg of P (DM basis) were excreted per fed beef animal. On average, 887 kg total manure (solids and water) were removed per finished animal (7.2 kg/animal/d) averaging 73% total …

A New Application For Fine Ground Rubber In The Control Of Odors From Livestock Manure Storage Structures, Lakshmi Koppolu, Richard K. Koelsch, Dennis D. Schulte, Crystal Powers, Dwaine Bundy

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

The purpose of this project was to quantify the odor and gas emission benefits of a fine ground rubber cover on laboratory scale manure storage units and to evaluate the ability of a fine ground rubber cover applied to a commercial swine manure storage unit to remain intact and functional over an extended period of time. A three-inch cover of fine ground rubber reduced odors by 77 to 99 percent from the manure storage tanks over a six-week period. However, consistent reductions of NH₃ emissions were not observed and H₂S emissions from all manure storage treatments were …

Bacteriophage-Based Tests For The Detection Of Mycobacterium Tuberculosis In Clinical Specimens: A Systematic Review And Meta-Analysis, Shriprakash Kalantri, Madhukar Pai, Lisa Pascopella, Lee Riley, Arthur Reingold

Public and Community Health Sciences Faculty Publications

Background: Sputum microscopy, the most important conventional test for tuberculosis, is specific in settings with high burden of tuberculosis and low prevalence of non tuberculous mycobacteria. However, the test lacks sensitivity. Although bacteriophage-based tests for tuberculosis have shown promising results, their overall accuracy has not been systematically evaluated.

Methods: We did a systematic review and meta-analysis of published studies to evaluate the accuracy of phage-based tests for the direct detection of M. tuberculosis in clinical specimens. To identify studies, we searched Medline, EMBASE, Web of science and BIOSIS, and contacted authors, experts and test manufacturers. Thirteen studies, all based on …

Mammalian Selenoprotein Thioredoxin-Glutathione Reductase, Dan Su, Sergey V. Novoselov, Qi-An Sun, Mohamed E. Moustafa, You Zhou, Richard Oko, Dolph L. Hatfield, Vadim N. Gladyshev

Vadim Gladyshev Publications

Thioredoxin reductases (TRs) are important redox regulatory enzymes, which control the redox state of thioredoxins. Mammals have cytosolic and mitochondrial TRs, which contain an essential selenocysteine residue and reduce cytosolic and mitochondrial thioredoxins. In addition, thioredoxin/glutathione reductase (TGR) was identified, which is a fusion of an N-terminal glutaredoxin domain and the TR module. Here we show that TGR is expressed at low levels in various tissues but accumulates in testes after puberty. The protein is particularly abundant in elongating spermatids at the site of mitochondrial sheath formation but is absent in mature sperm. We found that TGR can catalyze isomerization …

Theses and Dissertations

This qualitative study explored the experience of 32 traditional college freshmen women as they sought to choose a career with the idea of balancing career and family in the future. A traditional woman was defined as a woman whose central value system and cultural mores emphasize homemaking and childrearing as their primary role. Guided interviews were conducted to obtain in-depth descriptions of participants' experience. The interviews were transcribed and interpreted using a synthesis of qualitative methods based on Kvale's method. The six themes were as follows: 1. The concept of balancing careers and family life is not being discussed or …

Biofilm Removal Using Bubbles And Sound, Michael R. Parini

Theses and Dissertations

Bacteria in biofilms adhere well to surfaces and are quite difficult to remove. Oral plaque is one example of a biofilm. Many researchers have studied ways to remove plaque and bacteria from surfaces. It has been found that the passage of a bubble across a surface to which bacteria has adhered can remove the bacteria from the surface. Biofilms of Streptococcus mutans were grown on glass coverslips as a simple model for oral plaque. The coverslips were mounted in a Plexiglas chamber filled with artificial saliva. A bubble stream was directed at the mounted biofilm. The velocity, gas fraction, median …

Enhancement Of Calcium-Dependent Afterpotentials In Oxytocin Neurons Of The Rat Supraoptic Nucleus During Lactation, Ryoichi Teruyama, William E. Armstrong

Faculty Publications

The firing pattern of oxytocin (OT) hormone synthesizing neurons changes dramatically immediately before each milk ejection, when a brief burst of action potentials is discharged. OT neurons possess intrinsic currents that would modulate this burst. Our previous studies showed the amplitude of the Ca2+-dependent afterhyperpolarization (AHP) following spike trains is significantly larger during lactation. In the present study we sought to determine which component of the AHP is enhanced, and whether the enhancement could be related to changes in whole-cell Ca2+ current or the Ca2+ transient in identified OT or vasopressin (VP) neurons during lactation. We confirmed, with whole-cell current-clamp …

The Human Paf Complex Coordinates Transcription With Events Downstream Of Rna Synthesis., Bing Zhu, Subhrangsu S. Mandal, Anh-Dung Pham, Yong Zheng, Hediye Erdjument-Bromage, Surinder K. Batra, Paul Tempst, Danny Reinberg

Journal Articles: Biochemistry & Molecular Biology

The yeast PAF (yPAF) complex interacts with RNA polymerase II and coordinates the setting of histone marks associated with active transcription. We report the isolation and functional characterization of the human PAF (hPAF) complex. hPAF shares four subunits with yPAF (hCtr9, hPaf1, hLeo1, and hCdc73), but contains a novel higher eukaryotic-specific subunit, hSki8. RNAi against hSki8 or hCtr9 reduces the cellular levels of other hPAF subunits and of mono- and trimethylated H3-Lys 4 and dimethylated H3-Lys 79. The hSki8 subunit is also a component of the human SKI (hSKI) complex. Yeast SKI complex is cytoplasmic and together with Exosome mediates …

Teachers' Decision-Making About Place-Based Education And State Testing, Timothy G. Thomas

The Rural Educator

This qualitative study examined the effects of a high-stakes, standardized test on teachers' instructional planning at a rural school. The research addressed this question: How do mandated curricular standards affect teachers' instructional planning and content selection? Ethnographic interviews (Creswell, 1998) examined four secondary teachers' perceptions of the effects of high-stakes standardized tests on their work. Case study methodology (Yin, 1994) guided the analysis of the data. Each participant had several years' experience teaching at Mollusk Island School, and each teacher had previously included place-based lessons (e.g. environmental studies, cultural history) in his/her repertoire. Ultimately, the study explored how a community …

Recent Advances On The Taxonomy, Systematics And Epidemiology Of Trichinella, E. Pozio, D.S. Zarlenga

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

Since Owen first described Trichinella as a human pathogen in 1835, the number of organisms comprising this genus has grown dramatically. Where it was once thought to be a monospecific group, this genus is now comprised of eight species and three additional genotypic variants that have yet to be taxonomically defined. Along with the growth in the genus and description of the parasites has come a concomitant increase in our understanding of the epidemiology and geographical distribution of these organisms. Recent expansion of the non-encapsulated group to include three species biologically defined by their unique host ranges encompassing mammals, birds …

Land Grabbers, Toadstool Worshippers, And The Sagebrush Rebellion In Utah, 1979-1981, Jedediah S. Rogers

Theses and Dissertations

In 1979, a handful of Nevada state officials sparked a movement to transfer the large unappropriated domain to the western states. For two years what became known as the Sagebrush Rebellion swept across the American West like brushfire, engaging westerners of all stripes in a heated dispute over the question of the public lands. In Utah, as elsewhere in the West, public officials, rural ranchers, miners, developers, academics, environmentalists, and concerned citizens joined the debate and staked sides. This episode underscored western relationships between people and nature and featured contests over competing ideologies in the West. But it probably did …
