Bottom-Up And Top-Down Effects On Insects Herbivores Along A Natural Salinity Gradient In A Florida Salt Marsh, Maria Teresa Albarracin

USF Tampa Graduate Theses and Dissertations

I compared the strength of bottom- up and top-down effects on insect herbivores along a natural salinity gradient in salt marsh communities in West - Central, Florida. I used a 2x2 factorial design with plots divided into four different treatments: 1) fertilizer applied to increase plant quality 2) sticky traps added to remove natural enemies (parasitoids) 3) fertilizer applied and sticky traps added and 4) control plots. These plots were placed on 7 different sites containing the salt marsh plant Borrichia frutescens along a natural stress salinity gradient. In each plot I determined the abundance of the sap sucker Pissonotus …

An Investigation Of Tio2-Znfe2O4 Nanocomposites For Visible Light Photocatalysis, Jeremy Wade

USF Tampa Graduate Theses and Dissertations

Environmental pollution on a global scale is expected to be the greatest problem that chemical scientists will face in the 21st century, and an increasing number of these scientists are looking to new photocatalytic systems for the solution. Existing photocatalytic systems are effective for the decomposition of many unwanted organics through the use of efficient semiconductor photocatalysts activated by ultra-violet (UV) irradiation. The demand for visible light activated photocatalytic systems is increasing rapidly. Currently, however, the efficiency and availability of photocatalysts which can be activated effectively by the solar spectrum and especially indoor lighting is severely limited.

Trichinella Britovi Etiological Agent Of Sylvatic Trichinellosis In The Republic Of Guinea (West Africa) And A Re-Evaluation Of Geographical Distribution For Encapsulated Species In Africa, E. Pozio, P. Pagani, G. Marucci, D.S. Zarlenga, E.P. Hoberg, D. De Meneghi, G. La Rosa, L. Rossi

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

In West Africa, Trichinella infection was documented in humans and animals from Senegal in the 1960s, and the biological characters of one isolate showed a lower infectivity to domestic pigs and rodents when compared with that of a Trichinella spiralis pig isolate from Europe. To identify the Trichinella species present in West Africa, a survey was conducted in a total of 160 wild animals in the Republic of Guinea. Three Viverridae, one true civet (Viverra civetta) and two African palm civets (Nandinia binotata) from the Fouta Djallon Massif, Pilimini Subprefecture, were found positive by artificial digestion of muscle samples. Trichinella …

Modification Of Mdmx By Ubiquitination And Sumoylation, Yu Pan

USF Tampa Graduate Theses and Dissertations

MDM2 and MDMX are two major negative regulators of tumor suppressor p53. Both MDM2 and MDMX can inactivate p53 and play important roles in mouse embryonic development in a p53 dependent manner. MDM2 possesses ubiquitin E3 ligase activity and mediates self-ubiquitination as well as ubiquitination and degradation of p53 by proteasome. We identify MDMX as another ubiquitin E3 ligase substrate of MDM2. MDM2 promotes the ubiquitination and degradation of MDMX through proteasome pathway. The RING domains of both MDMX and MDM2 are required and sufficient for MDM2-mediated MDMX ubiquitination. ARF overexpression, DNA damage or MDM2 overexpression can all stimulate MDMX …

Development And Characterization Of Carbon Nanotubes For Sensor Applications, Jessica Eileen Otto

USF Tampa Graduate Theses and Dissertations

The aim of this research was to develop, characterize, and analyze carbon nanotubes as biosensors. In particular, pH and lactate molecules were targeted in this study. The reason these analytes were chosen was twofold. Firstly, when hydrogen ions and lactate are excreted in abnormal amounts in human sweat, they may be an indicator of a separate health problem. Thus, there is a clinical need for such biosensor applications. Secondly, pH and lactate detection represent two different types of electrochemical sensing techniques.

The carbon nanotubes used in this research were single walled and existed in bundles. They were further functionalized with …

The Expansion Of Intellectual Property Rights By International Agreement: A Case Study Comparing Chile And Australia’S Bilateral Fta Negotiations With The U.S., Ralph G. Fischer

ExpressO

This paper attempts to address the ongoing debate regarding the expansion of intellectual property rights (IPRs) through international negotiations. Commentators have described three theories that purport to explain the growing scope of IPRs in international law, as reflected in international agreements: that these agreements reflect coercion by economically powerful nations; that they are the products of lobbying by multinational corporations; and that they represent autonomous, welfare-enhancing instruments that benefit all parties. The article tests these theories by using a case study comparing free trade agreement negotiations that the United States recently concluded with a less developed country, Chile, and with …

Nucleic Acid Sequencing Using Charge-Switch Nucleotides, John G. K. Williams, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

The present invention provides compounds, methods and systems for sequencing nucleic acid using single molecule detection. Using labeled NPs that exhibit charge-switching behavior, single-molecule DNA sequencing in a microchannel sorting system is realized. In operation, sequencing products are detected enabling real-time sequencing as successive detectable moieties flow through a detection channel. By electrically sorting charged molecules, the cleaved product molecules are detected in isolation without interference from unincorporated NPs and without illuminating the polymerase-DNA complex.

Phylogenetic Relationship Of Forest Spiny Pocket Mice (Genus Heteromys) Inferred From Mitochondrial And Nuclear Markers With Implications For Species Boundaries, Malinda Wallentine Gonzalez

Theses and Dissertations

I constructed a best estimate phylogeny based on congruence of multiple data sources. In recent years molecular data has been used both to construct phylogenies of taxonomic groups and to aid in the delimitation of new species. I generated and analyzed sequence data for forest spiny pocket mice (Genus Heteromys) for the mitochondrial gene cyt b (1143 bp) and two nuclear gene segments MYH2 (252 bp) and EN2 (189 bp). I used maximum parsimony and Bayesian analyses to infer relationships among species and to provide a framework for using a species delimitation method to investigate the possibility of multiple …

Method And Device For Removal Of Cryoprotectant From Cryopreserved Biological Cells And Tissues, Dayong Gao, Xiangdong Cui

Biomedical Engineering Faculty Patents

Novel methods and devices for removing cryoprotectant from cryoprotectant-containing liquids, and from cells residing therein, are disclosed. In one aspect, the method comprises passing the cryoprotectant-containing liquid through at least one semipermeable hollow fiber membrane contained in a hollow module in a first direction, while passing a liquid which is substantially free of cryoprotectant through the hollow module in a second direction to remove cryoprotectant across a diffusion gradient. In another aspect, a device is described for removing cryoprotectant from a liquid, comprising a hollow module with at least one semipermeable hollow fiber membrane therein for accomplishing such counter-current diffusion …

Central Pattern Generator For Swimming In Melibe, Winsor H. Watson Iii, Stuart Thompson

Jackson Estuarine Laboratory

The nudibranch mollusc Melibe leonina swims by bending from side to side. We have identified a network of neurons that appears to constitute the central pattern generator (CPG) for this locomotor behavior, one of only a few such networks to be described in cellular detail. The network consists of two pairs of interneurons, termed `swim interneuron 1' (sint1) and `swim interneuron 2' (sint2), arranged around a plane of bilateral symmetry. Interneurons on one side of the brain, which includes the paired cerebral, pleural and pedal ganglia, coordinate bending movements toward the same side and communicate via non-rectifying electrical synapses. Interneurons …

A Gene Expression Fingerprint Of C. Elegans Embryonic Motor Neurons, Rebecca M. Fox, Stephen E. Von Stetina, Susan J. Barlow, Christian Shaffer, Kellen L. Olszewski, Jason H. Moore

Dartmouth Scholarship

Differential gene expression specifies the highly diverse cell types that constitute the nervous system. With its sequenced genome and simple, well-defined neuroanatomy, the nematode C. elegans is a useful model system in which to correlate gene expression with neuron identity. The UNC-4 transcription factor is expressed in thirteen embryonic motor neurons where it specifies axonal morphology and synaptic function. These cells can be marked with an unc-4::GFP reporter transgene. Here we describe a powerful strategy, Micro-Array Profiling of C. elegans cells (MAPCeL), and confirm that this approach provides a comprehensive gene expression profile of unc-4::GFP motor neurons in vivo.

Climate Change In Metropolitan Boston, Paul Kirshen, Matthias Ruth, William Anderson

New England Journal of Public Policy

Even though urban infrastructure systems are important and are designed according to socioeconomic and environmental conditions that are very sensitive to climate, there have been few major integrated assessments of the impacts of climate change on metropolitan infrastructure systems and services and possible adaptations. An analysis of the Boston metro area found that adaptation actions taken before full climate-change impacts occur will result in fewer expected negative impacts to the region than waiting for major impacts to occur. Adaptation of infrastructure to climate change must also consider land use management, environmental and socioeconomic impacts, equity, and adaptation actors and institutions. …

Grinding Decline In Springfield: Is The Finance Control Board The Answer?, Robert Forrant

New England Journal of Public Policy

Springfield, Massachusetts, the Bay State’s third largest city, suffered staggering manufacturing job loss over the last thirty years of the twentieth century. In 2004, the financial impact of job loss, coupled with dubious fiscal management, plunged the city into near bankruptcy. In response, state government passed legislation appointing a Finance Control Board to manage city business. Wage freezes for City workers were continued and cuts in numerous essential services occurred to deal with the debt. But the question remains, can a Control Board approach grow a large stock of well-paying jobs — large enough to grow the city’s and the …
