Ecological Dynamics Of Livebottom Ledges And Artificial Reefs On The Inner Central West Florida Shelf, Jennifer Maria Dupont

USF Tampa Graduate Theses and Dissertations

The West Florida Shelf (WFS) is one of the largest and most diversely-used continental shelf/slope systems in the world. The presence of paleoshorelines and scarped hardbottom outcrops (up to 4 m in relief) along the inner shelf (10-30 m depth) provide important habitat for a variety of infaunal, epifaunal, and fish assemblages that contribute to the productivity of the region. This dissertation will present a comprehensive overview of the geological, physical, and chemical settings of the inner West Florida Shelf, with particular focus on biological and ecological community dynamics of epibenthic macroinvertebrates, algae, and fish assemblages. Baseline and comparative data …

Rapid-Response Urban Cfd Simulations Using A Gpu Computing Paradigm On Desktop Supercomputers, Inanc Senocak, Julien C. Thibault, Matthew Caylor

Mechanical and Biomedical Engineering Faculty Publications and Presentations

In the event of chemical or biological (CB) agent attacks or accidents, first-responders need hazard prediction data to launch effective emergency response action. Accurate and timely knowledge of the wind fields in urban areas is critically important to identify and project the extent of CB agent dispersion to determine the hazard-zone. In their 2008 report (GAO-08-180), U.S. Government Accountability Office has reported that first responders are limited in their ability to detect and model hazardous releases in urban environments. The current set of modeling tools for contaminant dispersion in urban environments rely on empirical assumptions with diagnostic equations (Wang et …

Thermal Links For The Implementation Of An Optical Refrigerator, John Parker, David Mar, Steven Von Der Porten, John Hankinson, Kevin Byram, Chris Lee, Michael K. Mayeda, Richard C. Haskell, Qimin Yang, Scott R. Greenfield, Richard I. Epstein

All HMC Faculty Publications and Research

Optical refrigeration has been demonstrated by several groups of researchers, but the cooling elements have not been thermally linked to realistic heat loads in ways that achieve the desired temperatures. The ideal thermal link will have minimal surface area, provide complete optical isolation for the load, and possess high thermal conductivity. We have designed thermal links that minimize the absorption of fluoresced photons by the heat load using multiple mirrors and geometric shapes including a hemisphere, a kinked waveguide, and a tapered waveguide. While total link performance is dependent on additional factors, we have observed net transmission of photons with …

Understanding Rubber Friction In The Presence Of Water Using Sum-Frequency Generation Spectroscopy, Kumar Nanjundiah, Ping Yuan Hsu, Ali Dhinojwala

College of Polymer Science and Polymer Engineering

Infrared-visible sum-frequency-generation spectroscopy (SFG) was used to study the molecular structure of water between a poly(dimethylsiloxane) (PDMS) and a sapphire substrate. The observation of SFG peaks associated with the dangling surface hydroxyl groups (3690 cm(-1)) and water bands (3000-3400 cm(-1)) indicates that the contact spot between the PDMS lens and the sapphire substrate is heterogeneous. Within the contact spot there are regions where the methyl groups of the PDMS chains are in direct contact with the surface hydroxyl groups on the sapphire substrate. In the other regions, a thin water layer is trapped between the two surfaces with spectral features …

Adaptation Of The Bacterial Membrane To Changing Environments Using Aminoacylated Phospholipids, Hervé Roy, Kiley Dare, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Fine‐tuning of the biophysical properties of biological membranes is essential for adaptation of cells to changing environments. For instance, to lower the negative charge of the lipid bilayer, certain bacteria add lysine to phosphatidylglycerol (PG) converting the net negative charge of PG (−1) to a net positive charge in Lys‐PG (+1). Reducing the net negative charge of the bacterial cell wall is a common strategy used by bacteria to resist cationic antimicrobial peptides (CAMPs) secreted by other microbes or produced by the innate immune system of a host organism. The article by Klein et al. in the current issue of …

Keeping Fountain Grass Out Of The Mojave Desert, Curt Deuser

Lake Mead Science Symposium

Fountain Grass (Pennisetum setaceum) is an escaped ornamental perennial bunchgrass from Africa that has invaded parts of Hawaii and the Sonoran Desert. It is adapted to fire and increases hazardous fuels causing wildfires in areas that may not have historically occurred. It was detected in the late 1990’s within the Mojave Desert at Joshua Tree NP and along the Colorado River corridor on the shores of Lake Mohave. The extent of these populations was limited and a rapid response was necessary to keep it from spreading out of control. If no action is taken then fountain grass would spread by …

Athel (Tamarix Aphylla) And Athel Hybrid (Tamarix Aphyllax Tamarix Ramosissima)Establishment And Control At Lake Mead National Recreation Area, Carrie Norman, Curt Deuser, Joshua Hoines

Lake Mead Science Symposium

Athel is a large evergreen ornamental tree that has been planted throughout the Southwest since the 1950’s. Athel was considered benign because it was thought to produce non-viable seed unlike its invasive relative, tamarisk. However, athel began establishing in the wild from seed on Lake Mead in 1983. Lake Mead NRA has been actively controlling athel since November 2004 along the high water mark of Lake Mead shoreline (439 miles) to prevent it from spreading throughout the Colorado River Drainage. The NPS contracts Nevada Conservation Corp crews and the Lake Mead Exotic Plant Management Team to implement the control efforts …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …

Microarray And Cdna Sequence Analysis Of Transcription During Nerve-Dependent Limb Regeneration, James R. Monaghan, Leonard G. Epp, Srikrishna Putta, Robert B. Page, John A. Walker, Chris K. Beachy, Wei Zhu, Gerald M. Pao, Inder M. Verma, Tony Hunter, Susan V. Bryant, David M. Gardiner, Tim T. Harkins, S. Randal Voss

Biology Faculty Publications

Background

Microarray analysis and 454 cDNA sequencing were used to investigate a centuries-old problem in regenerative biology: the basis of nerve-dependent limb regeneration in salamanders. Innervated (NR) and denervated (DL) forelimbs of Mexican axolotls were amputated and transcripts were sampled after 0, 5, and 14 days of regeneration.

Results

Considerable similarity was observed between NR and DL transcriptional programs at 5 and 14 days post amputation (dpa). Genes with extracellular functions that are critical to wound healing were upregulated while muscle-specific genes were downregulated. Thus, many processes that are regulated during early limb regeneration do not depend upon nerve-derived factors. …

The Life Science Lawyer, Erin Albert

Butler University Books

Health care and life sciences are increasingly complex. There are many global players in life sciences and healthcare-patients, governments, hospitals, managed care companies, pharmaceutical, biotechnology, and medical device companies and pharmacies are only a few. With this increasing complexity comes a higher demand for hybrid professionals who can translate both the science as well as the legal issues surrounding this complicated environment. In the US, there are thousands of life science lawyers--people who have both a scientific/healthcare background and also who have gone on to law school (or in one case, vice versa). This book explores the following through interviews: …

Use Resistant Varieties To Combat Soybean Diseases, Save Money In '09, Loren J. Giesler, Sandi Alswager Karstens

Institute of Agriculture and Natural Resources: News Releases

LINCOLN, Neb. & As Nebraska farmers continue to make their seed selections for 2009, using resistant varieties to combat soybean diseases can not only save them headaches during the growing season but time and money.

This and other cost saving tips to help deal with high input costs in crop production can be found at UNL's Surviving High Input Costs in Crop Production (http://cropwatch.unl.edu/survivinghighinputcosts.htm) Web page.

When choosing varieties, the first thing to do is to select agronomic characteristics to match ground and other conditions, said Loren Giesler, University of Nebraska-Lincoln Extension plant pathologist.

Genic Regions Of A Large Salamander Genome Contain Long Introns And Novel Genes, Jeramiah J. Smith, Srikrishna Putta, Wei Zhu, Gerald M. Pao, Inder M. Verma, Tony Hunter, Susan V. Bryant, David M. Gardiner, Timothy T. Harkins, S. Randal Voss

Biology Faculty Publications

BACKGROUND: The basis of genome size variation remains an outstanding question because DNA sequence data are lacking for organisms with large genomes. Sixteen BAC clones from the Mexican axolotl (Ambystoma mexicanum: c-value = 32 x 10(9) bp) were isolated and sequenced to characterize the structure of genic regions.

RESULTS: Annotation of genes within BACs showed that axolotl introns are on average 10x longer than orthologous vertebrate introns and they are predicted to contain more functional elements, including miRNAs and snoRNAs. Loci were discovered within BACs for two novel EST transcripts that are differentially expressed during spinal cord regeneration and skin …

Structural Characterization Of The Hemophore Hasap From Pseudomonas Aeruginosa: Nmr Spectroscopy Reveals Protein-Protein Interactions Between Holo-Hasap And Hemoglobin, Aileen Y. Alontaga, Juan Carlos Rodriguez, Ernst Schönbrunn, Andreas Becker, Todd Funke, Erik T. Yukl, Takahiro Hayashi, Jordan Stobaugh, Pierre Moënne-Loccoz, Mario Rivera

Faculty Publications

Pseudomonas aeruginosa secretes a 205 residue long hemophore (full-length HasAp) that is subsequently cleaved at the C'-terminal domain to produce mainly a 184 residue long truncated HasAp that scavenges heme [Letoffé, S., Redeker, V., and Wandersman, C. (1998) Mol. Microbiol. 28, 1223-1234]. HasAp has been characterized by X-ray crystallography and in solution by NMR spectroscopy. The X-ray crystal structure of truncated HasAp revealed a polypeptide αβ fold and a ferriheme coordinated axially by His32 and Tyr75, with the side chain of His83 poised to accept a hydrogen bond from the Tyr75 phenolic acid group. NMR investigations conducted with full-length HasAp …
