A Mathematical Analysis Of The Dynamics Of Prion Proliferation, Meredith L. Greer, Laurent Pujo-Menjouet, Glenn F. Webb

All Faculty Scholarship

How do the normal prion protein (PrP(C)) and infectious prion protein (PrP(Sc)) populations interact in an infected host? To answer this question, we analyse the behavior of the two populations by studying a system of differential equations. The system is constructed under the assumption that PrP(Sc) proliferates using the mechanism of nucleated polymerization. We prove that with parameter input consistent with experimentally determined values, we obtain the persistence of PrP(Sc). We also prove local stability results for the disease steady state, and a global stability result for the disease free steady state. Finally, we give numerical simulations, which are confirmed …

A Qualitative Study Of Early Family Histories And Transitions Of Homeless Youth, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Using intensive qualitative interviews with 40 homeless youth, this study examined their early family histories for abuse, neglect, and other family problems and the number and types of transitions that youth experienced. Multiple forms of child maltreatment, family alcoholism, drug use, and criminal activity characterized early family histories of many youth. Leaving home because of either running away or being removed by child protective services often resulted in multiple transitions, which regularly included moving from foster care homes to a group home, back to their parents, and then again returning to the streets. Although having experienced family disorganization set youth …

Spinobulbar Neurons In Lamprey: Cellular Properties And Synaptic Interactions, James F. Einum, James T. Buchanan

Biological Sciences Faculty Research and Publications

An in vitro preparation of the nervous system of the lamprey, a lower vertebrate, was used to characterize the properties of spinal neurons with axons projecting to the brain stem [i.e., spinobulbar (SB) neurons)]. To identify SB neurons, extracellular electrodes on each side of the spinal cord near the obex recorded the axonal spikes of neurons impaled with sharp intracellular microelectrodes in the rostral spinal cord. The ascending spinal neurons (n = 144) included those with ipsilateral (iSB) (63/144), contralateral (cSB) (77/144), or bilateral (bSB) (4/144) axonal projections to the brain stem. Intracellular injection of biocytin revealed that the …

Gene Flow In Complex Landscapes: Testing Multiple Hypotheses With Causal Modeling., Samuel A. Cushman, Kevin Scot Mckelvey, Jim Hayden, Michael K. Schwartz

Wildlife Biology Faculty Publications

Predicting population-level effects of landscape change depends on identifying factors that influence population connectivity in complex landscapes. However, most putative movement corridors and barriers have not been based on empirical data. In this study, we identify factors that influence connectivity by comparing patterns of genetic similarity among 146 black bears (Ursus americanus), sampled across a 3,000-km2 study area in northern Idaho, with 110 landscape-resistance hypotheses. Genetic similarities were based on the pairwise percentage dissimilarity among all individuals based on nine microsatellite loci (average expected heterozygosityp0.79). Landscape-resistance hypotheses describe a range of potential relationships between movement cost and land cover, slope, …

Invasion Through Quantitative Effects: Intense Shade Drives Native Decline And Invasive Success, Kurt O. Reinhart, Julie Gurnee, Reyes Tirado, Ragan M. Callaway

Biological Sciences Faculty Publications

The effects of invasive nonnative species on community composition are well documented. However, few studies have determined the mechanisms by which invaders drive these changes. The literature indicates that many nonnative plant species alter light availability differently than natives in a given community, suggesting that shading may be such a mechanism. We compared light quantity (photosynthetically active radiation, PAR) and quality (red : far-red ratio, R:Fr) in riparian reaches heavily invaded by a nonnative tree (Acer platanoides) to that in an uninvaded forest and experimentally tested the effects of our measured differences in PAR and R:Fr on the …

Sex-Role Orientation, Women As Managers And Transformational Leadership Among Female Law Firm Partners And Subordinates, Nathalie Lynch-Walsh

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Nearly 30% of all attorneys in the U.S. are women, but only 17% of all partners in major U.S. law firms are women. The disparity in the number of women at the top of the legal profession echoes the shortage of women at the helm of major U.S. corporations. Traditional sex-role stereotypes represent one type of "glass ceiling" barrier and stem from the different behavioral norms assigned to men (agentic) and women (communal) based on relative social status. Women exhibiting nonconforming behavior are less liked than conforming women. Conversely, women exhibiting agentic behaviors such as selfconfidence and assertiveness are seen …

Year-Round Diet Of The Marsh Rice Rat, Oryzomys Palustris, In Virginia Tidal Marshes, Robert K. Rose, Shannon W. Mcgurk

Virginia Journal of Science

The marsh rice rat, Oryzomys palustris, is the dominant semi-aquatic rodent living in tidal marshes of the Virginia coastal plain. Described as highly carnivorous, this species is known to consume a range of animal foods, including crustaceans, mollusks, fish, and arthropods, as well as some plant foods. Analysis of stomach contents from rice rats collected from Eastern Shore tidal marshes throughout an annual cycle revealed that all 103 stomachs contained dicots, 82 percent had monocots, 61 percent had crabs and insects, and 38 percent had snails. Thirty-eight percent of stomachs contained foods in all five categories, no stomach was …

The Effects Of Ultrashort Pulsed Electric Fields On The Fluorescent Molecule Bodipy Fl C5 Ceramide, Rachael Sara Shevin

Electrical & Computer Engineering Theses & Dissertations

Nanosecond pulsed electric fields are able to manipulate internal cell organelles by taking advantage of the small but finite time required for charge to establish across a capacitive barrier. Pulsed electric fields also affect macromolecular structures such as enzymes and proteins. Application of a single nanosecond pulsed electric field decreases the fluorescence of a commercially available biological dye Bodipy FL C₅ Ceramide, used to observe the Golgi apparatus of living cells. The effect is seen when the fluorophore is exposed to an electric field both in vitro and when incorporated into the Golgi of a living Jurkat cell. Observation …

Characterization Of Β-Lactam Resistant Pandemic Serotypes Of Vibrio Cholerae Isolated From Ships' Ballast Tanks And Coastal Waters, Amanda Lynn Goodrich

OES Theses and Dissertations

Vibrio cholerae serotypes 01 and 0139 are responsible for world-wide epidemics of cholera. These pandemic causing strains must possess genes that encode for the cholera toxin (CTX) and toxin co-regulated pili (TCP) in order to infect their hosts. In this study, 284 isolates of Vibrio cholerae from ballast and coastal waters were serotyped, with 11 % testing positive for serotype 01 and 21 % testing positive for serotype 0139. PCR assays were used to detect the presence of ctxA and tcpA genes in all positive isolates, none of which contained ctxA while 2% of the isolates contained tcpA. The 01 …

Effects Of Long-Term Hypoxia On Enzymes Of Carbohydrate Metabolism In The Gulf Killifish, Fundulus Grandis, Bernard Rees

Biological Sciences Faculty Publications

The goal of the current study was to generate a comprehensive, multi-tissue perspective of the effects of chronic hypoxic exposure on carbohydrate metabolism in the Gulf killifish Fundulus grandis. Fish were held at approximately 1.3 mg l(-1) dissolved oxygen (approximately 3.6 kPa) for 4 weeks, after which maximal activities were measured for all glycolytic enzymes in four tissues (white skeletal muscle, liver, heart and brain), as well as for enzymes of glycogen metabolism (in muscle and liver) and gluconeogenesis (in liver). The specific activities of enzymes of glycolysis and glycogen metabolism were strongly suppressed by hypoxia in white skeletal muscle, …

Are Vultures Birds, And Do Snakes Have Venom, Because Of Macro- And Microscavenger Conflict?, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

I outline models that describe vertebrate and microbial competition for carrion resources and help explain the resultant morphologies observed in extant vertebrate scavengers. Odors from microbial decomposition signal the presence of a carcass to vertebrate scavengers. Therefore, microbes must consume carcasses rapidly or evolve toxic defenses to protect themselves and their resource from their vertebrate competitors. Similarly, macroscavengers must evolve traits that allow rapid detection of carcasses or develop chemical defenses against microbial toxins. My modeling suggests that the most efficient macroscavenger adaptations increase the probability of carcass detection, which explains why highly vagile species, such as vultures, are the …

Fisheries Research Contract Report No. 15 - Aquatic Animal Health Subprogram: Pilchard Herpesvirus Infection In Wild Pilchards (Frdc Project No. 2002/044) Final Report, Brian Jones, Melanie Crockford, Richard Whittington, Mark Crane, Graham Wilcox

Fisheries Research Contract Reports

In 1995 and again in 1998/9, millions of pilchards (Sardinops sagax neopilchardus) were found dead or dying off the coast of Australia. Some pilchards in New Zealand were also affected during the 1995 epizootic. The epizootics moved progressively in a "bushfire-like" manner against the prevailing currents at a rapid speed. An uncharacterised herpesvirus, pilchard herpesvirus (PHV), was associated with both mortality events and, based on its occurrence in affected fish and the disease pathogenesis, generally accepted as the causative agent, although experimental evidence of its role was not established. Until recently, rapid and sensitive methods to detect PHV were not …

Cognitive Benefits Of Participation In Lifelong Learning Institutes, Patricia M. Simone, Melinda Scuilli

Psychology

This essay examines the role of cognitive stimulation in maintaining high cognitive functioning in later life. Cognition is dependent upon brain function and brain function can be improved through physical exercise and cognitive stimulation. Lifelong learning institutes offer older adults a myriad of opportunities to enhance their cognitive function. These institutes are not unique to the United States and need not offer courses in any particular format in order to facilitate cognitive benefits.

Random Flows And Diagnostics Of Turbulence In The High Latitude Cirrus, Steven N. Shore, Ted N. Larosa, Raymond J. Chastain, Loris Magnani

Faculty Articles

Aims: We present an analysis of the exceptionally turbulent velocity field in the high Galactic latitude cirrus cloud MBM 3. As in the other translucent clouds in our study (MBM 16 and MBM 40), there is no evidence for internal star formation. However, the large scale velocity variation in this cloud is more pronounced. Methods: We have mapped the cloud in 12CO and 13CO (1-0) at high spatial (0.03 pc) and velocity (0.06 km s-1) resolution. We constructed several velocity probability density functions (PDFs), estimated the turbulent transfer rate, and analyzed the linewidths as a function of the size of …

Positive Solutions Of A Nonlinear N-Th Order Eigenvalue Problem, John R. Graef, Johnny Henderson, Bo Yang

Faculty Articles

For 1/2 < p < 1 fixed, values of lambda > 0 are determined for which there exist positive solutions of the n-th order differential equation u((n)) = lambda g(t)f(u), 0 < t < 1, satisfying the three-point boundary conditions, u((i-1)) (0) = u((n-2)) (P) = u((n-1)) (1) = 0, 1

The problem is converted to a third order differential-integro boundary value problem and then a recent result of Graef and Yang for third order boundary value problems is adapted. An example is included to illustrate the results.

Did Nepa Drown New Orleans? The Levees, The Blame Game, And The Hazards Of Hindsight, Douglas A. Kysar, Thomas O. Mcgarity

Duke Law Journal

This Article highlights the. hazards of hindsight analysis of the causes of catastrophic events, focusing on theories of why the New Orleans levees failed during Hurricane Katrina in 2005 and particularly on the theory that the levee failures were "caused" by a 1977 National Environmental Policy Act (NEPA) lawsuit that resulted in a temporary injunction against the Army Corps of Engineers' hurricane protection project for New Orleans. The Article provides a detailed historical reconstruction of the decision process that eventuated in the New Orleans storm surge protection system, focusing both on the political and legal factors involved and on the …
