Phanerozoic Surface History Of The Slavecraton, Alexis K. Ault, Rebecca M. Flowers, Samuel A. Bowring

Geosciences Faculty Publications

New apatite (U-Th)/He (AHe) thermochronometry data and key geologic constraints from Slave craton kimberlites are used to develop a model for the Phanerozoic burial, unroofing, and hypsometric history of the northwestern Canadian shield. AHe dates range from 210 ± 13 to 382 ± 79 Ma, are older in the eastern Slave craton and decrease westward, and resolve the spatial extent, thickness, and history of now-denuded sedimentary units. Results indicate Paleozoic heating to temperatures ≥85–90°C, suggesting regional burial beneath ≥2.8 km of strata while the region was at sea level, followed by the westward migration of unroofing across the craton. This …

New Questions, Multiple Meanings : Exploring Attachment Theory, Self Psychology, And Anti-Oppression Perspectives On Human-Companion Animal Relationships In The Rural West, Sarah H. Winchester

Theses, Dissertations, and Projects

In spite of burgeoning interest in the significance of human-companion animal relationships in social work and related fields, the theoretical conceptualization of these relationships in the context of mental health remains largely limited to the cross-species and cross-cultural application of Attachment Theory. Further, the literature on human-companion animal relationships through the lens of Attachment Theory reflects a narrow scope of research methodologies and demographic variables, thus leaving the unique, multiple meanings of these relationships – and their intersections with varying and marginalized sociocultural identities – largely unexplored. In order to address these gaps and expand theoretical discourse on the phenomenon, …

In The Environment : Clinician Perspectives On Nature And Psychological Health, Benjamin D. White

Theses, Dissertations, and Projects

This qualitative study explores the relationship between nature and psychological health from the perspectives of 12 clinicians from a variety of training backgrounds. During 30 to 45- minute interviews, participants were asked a variety of questions about their personal and clinical experience as they have informed their perspectives on the question: How does nature influence psychological health? Major findings of the study showed there to be a significant difference between the importance of nature in clinicians' personal lives and nature's role in clinical practice. Findings indicated that although nature was important to participants' personal psychological well-being that nature was not …

Method Of Drug Delivery By Carbon Nanotube-Chitosan Nanocomplexes, Shyam S. Mohapatra, Arun Kumar

USF Patents

Functionalized Single Wall Carbon Nanotube (SWCNT) complexed with nanochitosan for use in the delivery of bioaffecting substances and diagnostic applications. fSWCNT complexed with the chitosan NG042 were used for delivery of DNA-encoding EGFP reporter protein and peptide. The results demonstrate that shown CNT-chitosan hybrid nanoparticles exhibit significantly higher transfection efficiency in vivo than chitosan alone. Furthermore, the functionalized nanotubes were tested for peptide transfer into HEK293 cells. The results showed that the hybrid nanoparticles efficiently transferred peptides. Together, these results show that hybrid SWCNT-chitosan particles increase DNA and peptide transfer into cells.

Solids Retention Time Uncoupling By Selective Wasting Of Sludge, Peter G. Stroot

USF Patents

Fluorescence in situ hybridizations were used to identify and determine the abundance of nitrifying bacteria and Anammox bacteria (recycling bacteria) in freshly settled sludge of biological nutrient removal (BNR) secondary clarifiers. An uneven distribution was observed for recycling bacteria in two BNR systems. Settling patterns suggest microcolony formation processes are sensitive to the internal recycle rate, which allow for rapid recycling bacteria microcolony growth by increasing circulation of flocs through the aeration and anoxic basins. Sludge containing high levels of recycling bacteria are selectively collected and separated from the remaining sludge, uncoupling the solids retention time (SRT) of the recycling …

Tigers and their close relatives (Panthera) are some of the world’s most endangered species. Here we report the de novo assembly of an Amur tiger whole-genome sequence as well as the genomic sequences of a white Bengal tiger, African lion, white African lion and snow leopard. Through comparative genetic analyses of these genomes, we find genetic signatures that may reflect molecular adaptations consistent with the big cats’ hypercarnivorous diet and muscle strength. We report a snow leopard-specific genetic determinant in EGLN1 (Met39>Lys39), which is likely to be associated with adaptation to high altitude. We also detect a …

Transient And Selective Suppression Of Neural Activity With Infrared Light, Michael W. Jenkins, Hui Lu, Jeffrey M. Mcmanus, Hillel J. Chiel

Faculty Scholarship

Analysis and control of neural circuitry requires the ability to selectively activate or inhibit neurons. Previous work showed that infrared laser light selectively excited neural activity in endogenous unmyelinated and myelinated axons. However, inhibition of neuronal firing with infrared light was only observed in limited cases, is not well understood and was not precisely controlled. Using an experimentally tractable unmyelinated preparation for detailed investigation and a myelinated preparation for validation, we report that it is possible to selectively and transiently inhibit electrically- initiated axonal activation, as well as to both block or enhance the propagation of action potentials of specific …

Critical Connectivity In Banking Networks, Agam Gupta, Molly M. King, James Magdanz, Regina Martinez, Matteo Smerlak, Brady Stoll

Sociology

The financial crisis of 2007-2009 demonstrated the need to understand the macrodynamics of interconnected financial systems. A fruitful approach to this problem regards financial infrastructures as weighted directed networks, with banks as nodes and loans as links. Using a simple banking model in which banks are linked through interbank lending, with an exogenous shock applied to a single bank, we find a closedform analytical solution for the degree at which failures begin to propagate in the network. This critical degree is expressed as a function of four financial parameters: banking leverage; interbank exposure; return on the investment opportunity; and interbank …

Nanopore Surface Coating Delivers Nanopore Size And Shape Through Conductance-Based Sizing, Cameron M. Frament, Y. M. Nuwan D.Y. Bandara, Jason R. Dwyer

Chemistry Faculty Publications

The performance of nanopore single-molecule sensing elements depends intimately on their physical dimensions and surface chemical properties. These factors underpin the dependence of the nanopore ionic conductance on electrolyte concentration, yet the measured, or modeled, dependence only partially illuminates the details of geometry and surface chemistry. Using the electrolyte-dependent conductance data before and after selective surface functionalization of solid-state nanopores, however, introduces more degrees of freedom and improves the performance of conductance-based nanopore characterizations. Sets of representative nanopore profiles were used to generate conductance data, and the nanopore shape and exact dimensions were identified, through conductance alone, by orders-of-magnitude 3 …

Winter Activity Of Bats In Cache, Juab And Utah Counties, Utah, Benjamin T. Jones, Dr. Duke S. Rogers

Journal of Undergraduate Research

Historically, studies of bat activity have been conducted during spring, summer and fall when migratory bats are most abundant and non-migratory bats are most active. Due to the high energy expenditure required to maintain body temperatures sufficient for flight (Fenton, 1992) and the low availability of aerial insects, (Whitaker and Rissler, 1992) activity levels decline markedly with the onset of winter and the corresponding fall in temperatures. Non-migratory bats conserve energy by hibernating through the winter. However, in previous winter surveys conducted in Southern Utah, five of sixteen species know to occur in that area were netted. (Hasenyager, 1980) Bats …

Phylogenetic Analyses Of The Geographic Origin Of Stlv-I And Htlv-I With Extensive Sequence Sampling: Evidence For An African Origin With Subsequent Separate Viral Evolution In Asia And Africa, Chris R. Kelsey, Dr. Keith A. Crandall

Journal of Undergraduate Research

Human T-cell lymphotropic virus type I (HTLV-I) is a retrovirus believed to be the etiologic agent of adult T-cell leukemia/lymphoma (ATL) and HTLV-I -associated myelopathy/ tropical spastic paraparesis (HAM/TSP). HTLV-I is a member of a related group of retroviruses, known collectively as primate T-cell lymphotropic viruses (PTLV) which also include human T-cell lymphotropic virus type II (HTLV-II) and the simian T-cell lymphotropic virus type I (STLV-I). In an attempt to better understand phylogenetic relationships among geographically diverse strains of PTLV-I, and in the process gain more insight into the geographic origin of STLV-I and HTLV-I, a comprehensive study involving multiple …

Pediatric Study To Determine The Extent Of Parasympathetic Reinnervation To The Human Heart Post Transplant, Aaron W. Jones, R. Paul Evans

Journal of Undergraduate Research

Until recently, it had been assumed that following cardiac transplantation, nerve impulses to the heart were permanently disconnected. Within the past few years, multiple studies prompted by patient complaints, observations, and simple curiosity have proven the surprising fact that the accelerator (or sympathetic) nerves to the heart almost always regrow.1 Furthermore, in a large segment of the recipient population, the same is found for the sensory nerves which relay pain and oxygen supply status of the heart to the brain.2 These discoveries have led scientists worldwide on the search for evidence of the regrowth of the decelerator (or parasympathetic) nerves …
