Diet, Feeding Ecology, Trophic Relationships, Morphometric Condition, And Ontogeny For The Sandbar Shark, Carcharhinus Plumbeus, And Smooth Dogfish, Mustelus Canis, Within The Delaware Bay Estuary, William David Mcelroy

Open Access Dissertations

Feeding ecology and condition were examined for sandbar shark, Carcharhinus plumbeus, and smooth dogfish, Mustelus canis, in Delaware Bay. Prey quantity indicated continuous feeding by M. canis, but female sharks had significantly greater quantities of prey than males. Small sharks fed on annelids, isopods, shrimp, bivalves and crabs, and significant shifts occurred in larger sharks to a diet dominated by large crabs with some gastropods and teleosts. Limited monthly shifts were evident. These were likely influenced by changes in prey availability but also by ontogeny in small M. canis. Feeding in C. plumbeus was intermittent, with episodic consumption of large …

The Use Of Cnidarian Nematocysts By The Aeolidian Nudibranch Cratena Pilata, Sarah Fogg-Matarese

Open Access Dissertations

Nudibranchs feed on anemones and hydroid polyps. The ingested cnidarian nematocysts are stored in cerata, dorsal extensions of the gut, and used to defend against predatation. Specialized smooth muscle sacs in the cerata, the cnidosacs, contain modified epithelial cells, the cnidophages, that hold the nematocysts. Light microscopic and behavioral studies indicate that, upon adequate stimulation, the cnidosac and cerata contract, opening the ceras tip and releasing the stored nematocysts. Ultra-thin sections revealed that the smooth muscle cells of the ceras encompass a network of caveolae and that synaptic terminals containing dense-cored and clear vesicles impinge on the muscles of the …

Ocean Engineering and Marine Sciences Faculty Publications

The biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data. Tests using modern pollen data from 381 samples derived from 287 locations broadly reproduce potential natural vegetation. The strong temperature gradient associated with the Andes is recorded by a transition from high altitude cool grass/shrubland and cool mixed forest to mid-altitude cool temperate rain forest, to tropical dry, seasonal and rain forest at low altitudes. Reconstructed biomes from a number of sites do not match the potential vegetation due to local factors such as human …

The Doctrine Of Sin In The Thought Of George R. Knight: Its Context And Implications, Jamie Kiley

Master's Theses

George R. Knight attempts to chart a middle course between various historical extremes on the doctrine of sin. His view of the Fall and of the consequent effects on human nature is not as pessimistic as that of theologians in the Augustinian tradition (including Martin Luther and John Calvin), who stress the complete corruption of human nature and the loss of free will. On the other hand, Knight’s view is not as optimistic as the views of such theologians as Pelagius or M. L. Andreasen, who tend not to see the Fall as having affected human nature itself, and believe …

Collection Of Moodna Bisinuella (Lepidoptera: Pyralidae) From Field Corn In Mississippi, M. Willrich Siebert, R. L. Brown

Midsouth Entomologist

Observation of Moodna bisinuella Hampson in Mississippi was based on specimens collected near Greenville (Washington Co.), Mississippi during August 2008. Larvae were collected from ears of field corn, Zea mays L., reared to adults, and identified by using characters observed from the dissection of the male genitalia. Little information is available to describe larval ecology, injury to field corn, available control measures, or distribution across Mississippi.

The Impact Of Early Positive Results On A Mathematics And Science Partnership: The Experience Of The Institute For Chemistry Literacy Through Computational Science, K. S. Murray, M. A. Henry, M. C. Hogrebe

Journal of Mathematics and Science: Collaborative Explorations

After one year of implementation, the Institute for Chemistry Literacy through Computational Science, an NSF Mathematics and Science Partnership Institute Project led by the University of Illinois at Urbana-Champaign’s Department of Chemistry, College of Medicine, and National Center for Supercomputing Applications, experienced statistically significant gains in chemistry content knowledge among students of the rural high school teachers participating in its intensive, year-round professional development course, compared to a control group. The project utilizes a two-cohort, delayed-treatment, random control trial, quasi-experimental research design with the second cohort entering treatment one year following the first. The three-year treatment includes intensive two-week summer …

A Remote Sensing And Gis-Assisted Spatial Decision Support System For Hazardous Waste Site Monitoring, John R. Jensen, Michael E. Hodgson, Maria Garcia-Quijano, Jungho Im, Jason A. Tullis

Faculty Publications

Humans produce large amounts of waste that must be processed or stored so that it does not contaminate the environment. When hazardous wastes are stored, waste site monitoring is typically conducted in situ which can lead to a serious time lag between the onset of a problem and detection. A Remote Sensing and GIS-assisted Spatial Decision Support System for Hazardous Waste Site Monitoring was developed to improve hazardous waste site management. The system was designed to be recursive, flexible, and integrative. It is recursive because the system is implemented iteratively until the risk assessment subsystem determines that an event is …

Estimating The System Costs Of Wind Power Forecast Uncertainty, Judith Cardell, C. Lindsay Anderson, Chin Yen Tee

Engineering: Faculty Publications

Uncertainty in forecasts of wind power generation raises concerns of integrating wind power into power system operations and electricity markets at acceptable costs. The analysis presented in this paper uses an optimal power flow (OPF) model in a Monte Carlo Simulation (MCS) framework to estimate the additional cost of power system operation with uncertain output from a wind farm. A base case dispatch is established along with alternate dispatches based upon a probability distribution of real time wind power generation. The cost of the uncertainty in wind power forecasts is then quantified in terms of the difference in production cost …

Role Of Cyclophilin D In Secondary Spinal Cord And Brain Injury, Jordan Mills Clark

University of Kentucky Doctoral Dissertations

In the hours and days following acute CNS injury, a secondary wave of events is initiated that exacerbate spinal tissue damage and neuronal cell death. A potential mechanism driving these secondary events is opening of the mitochondrial permeability transition pore (mPTP) and subsequent release of several cell death proteins. Previous studies have shown that inhibition of cyclophilin D(CypD), the key regulating component in mPTP opening, was protective against insults that induce necrotic cell death. We therefore hypothesized that CypD-null mice would show improved functional and pathological outcomes following spinal cord injury (SCI) and traumatic brain injury (TBI). Moderate and severe …

Glutamate Regulation In The Hippocampal Trisynaptic Pathway In Aging And Status Epilepticus, Michelle Lee Stephens

University of Kentucky Doctoral Dissertations

A positive correlation exists between increasing age and the incidence of hippocampal-associated dysfunction and disease. Normal L-glutamate neurotransmission is absolutely critical for hippocampal function, while abnormal glutamate neurotransmission has been implicated in many neurodegenerative diseases. Previous studies, overwhelmingly utilizing ex vivo methods, have filled the literature with contradicting reports about hippocampal glutamate regulation during aging. For our studies, enzyme-based ceramic microelectrode arrays (MEA) were used for rapid (2 Hz) measurements of extracellular glutamate in the hippocampal trisynaptic pathway of young (3-6 months), late-middle aged (18 mo.) and aged (24 mo.) urethane-anesthetized Fischer 344 rats. Compared to young animals, glutamate terminals …

Iterative Methods For Computing Eigenvalues And Exponentials Of Large Matrices, Ping Zhang

University of Kentucky Doctoral Dissertations

In this dissertation, we study iterative methods for computing eigenvalues and exponentials of large matrices. These types of computational problems arise in a large number of applications, including mathematical models in economics, physical and biological processes. Although numerical methods for computing eigenvalues and matrix exponentials have been well studied in the literature, there is a lack of analysis in inexact iterative methods for eigenvalue computation and certain variants of the Krylov subspace methods for approximating the matrix exponentials. In this work, we proposed an inexact inverse subspace iteration method that generalizes the inexact inverse iteration for computing multiple and clustered …

Fabrication Of Nanostructures For Improved Performance Of Electrochemical Sensors And For Reference Compensation In Localized Surface Plasmon Resonance Sensors, Prashanthi Para

University of Kentucky Master's Theses

L‐glutamate is associated with several neurological disorders; thus, monitoring fast dynamics of L‐glutamate is of great importance in the field of neuroscience. Electrode miniaturization demanded by many applications leads to reduced surface area and decreased amounts of immobilized enzymes on coated electrodes. As a result, lower signal‐to‐noise ratios are observed for oxidase‐enzyme based sensors. To increase the signal‐to‐noise ratio we have developed a process to fabricate micro‐ and nano‐ structures on the microelectrode surface.

Localized surface‐plasmon resonances (SPR) has been extensively used to design label‐free biosensors that can monitor receptor‐ligand interactions. A major challenge with localized SPR sensors is that …

Journal Articles

This article addresses the impact of integration of academia, industry, and government on the public nature of research. The article concludes that, while the integration has benefited science immensely, regulatory measures should be taken to restore the public nature of research in an age of integration.

Report On Wintering Western Snowy Plovers At Coos Bay North Spit And Impacts To Plovers From The North Jetty Repair Project, Winter 2009, David J. Lauten, Kathleen J. Castelein, Eleanor P. Gaines

Institute for Natural Resources Publications

The Western Snowy Plover (Charadrius alexandrinus nivosus) breeds along the coast of the Pacific Ocean in California, Oregon, and Washington and at alkaline lakes in the interior of the western United States (Page et al. 1991). Loss of habitat, predation pressures, and disturbance have caused the decline of the coastal population of Snowy Plovers and led to the listing of the Pacific Coast Population of Western Snowy Plovers as Threatened on March 5, 1993 (U.S. Fish and Wildlife Service 1993). Oregon Western Snowy Plovers are known to winter along the coast of Oregon as well as migrate to …

Four years ago at the age of 34, I heard the awful words "I'm sorry, but you have breast cancer" coming from my doctor. After the initial shock of the diagnosis wore off, I like many others who have faced life-threatening diseases began to work with a team of physicians to develop an appropriate treatment plan, which included contemplating enrollment in a clinical trial. Quite unexpectedly, my position as an intellectual property professor whose scholarship focuses primarily on information control, my role as a member of my university's Institutional Review Board that oversees studies involving human subjects, and my newly …

A Longitudinal Examination Of The Contribution Of Perceived Motor Competence And Actual Motor Competence To Physical Activity In 6 To 9 Year Old Children, Fleur Mcintyre

Theses

This study examined the relationship between perceived motor competence, actual motor competence and physical activity. In particular, it aimed to identify the impact of perceived motor competence (PMC), actual motor competence (AMC), and age and gender on the physical activity levels of young children. A number of factors have been identified as key contributors to children’s physical activity levels. However, there had been little investigation into their developing impact and subsequent relationship with emergent physical activity levels, particularly in the younger primary age groups.

Physical activity, AMC and PMC measures were collected from 6-, 7-, 8-, and 9-year-old boys and …

Fighting Against Biopiracy: Does The Obligation To Disclose In Patent Applications Truly Help?, Jacques De Werra

Vanderbilt Journal of Transnational Law

In the global fight against biopiracy, one of the key issues is to prevent the grant and exploitation of patents on traditional knowledge and genetic resources by requiring that patent applicants for inventions involving traditional knowledge and genetic resources disclose the source of those resources and provide evidence that the prior informed consent of the local owners of such resources has been obtained and that benefit-sharing agreements have been entered into with those owners.

This Article argues that a legal discussion of biopiracy should analyze the obligation to disclose the use of traditional knowledge and genetic resources in an invention …

The Arctic: An Opportunity To Cooperate And Demonstrate Statesmanship, Dr. Hans Corell

Vanderbilt Journal of Transnational Law

The Article discusses in four distinct parts disputes relating to maritime boundaries in the Arctic; "gaps" in the legal regime in the Arctic; environmental and security concerns; and the administration of the Arctic.

Regarding the first item, the Article maintains that the point of departure is that the United Nations Convention on the Law of the Sea applies also in the Arctic. Overlapping claims by the coastal states are perfectly legitimate and thus should not be dramatized. What matters is how such differences are resolved.

Referring to suggestions that there are "gaps" in the Arctic legal regime and that a …

The Arctic In World Environmental History, Jonathan D. Greenberg

Vanderbilt Journal of Transnational Law

For millions of years, the Arctic has been the world's most important "barometer of global change and amplifier of global warming." For twenty thousand years, the Arctic has been the homeland of modern human settlement, and it has played a central role in the interplay between global climate change and human migration throughout Eurasia and the Americas. Since the late fifteenth century, Arctic aboriginal peoples, lands, and seas have been thoroughly integrated into the international history of European trade, capitalism, and colonization; the territorial expansion of modern nation states; and the transnational strategic history since the outset of the Cold …

Social Analysis Of Cleft Lip And Palate Abnormality In Nigeria, Alice Umweni, Kokunre Agbontaen-­‐Eghafona, Hartwig Sauter

Journal of Social, Behavioral, and Health Sciences

This study examined cleft lip and palate from the sociological point of view. It looked at the social aspects of a health issue by examining the social problems that may emanate from cleft lip/palate deformity. Questionnaires were administered in northern Nigeria to 32 patients between the ages of 10 and 60 who had been born with the defect. Oral interviews using the same set of questions were conducted with 18 patients with similar defects of cleft lip/palate deformity in southern Nigeria. The questionnaire method was preferred by the respondents in the north, whereas the respondents in the south preferred the …

Menopausal Problems Among Rural And Urban Women From Eastern India, Doyel Dasgupta, Subha Ray

Journal of Social, Behavioral, and Health Sciences

The present study sought to examine variations in menopausal characteristics between rural and urban women and the ways in which these characteristics could be predicted from differential sociodemographic variables related to the residential status. Data on sociodemographic variables, reproductive history, and menopausal symptoms were collected from 180 postmenopausal women (rural 110; urban 70) belonging to the Bengali-speaking Hindu ethnic group of eastern India. Bivariate analyses confirmed rural-urban differences in menopausal age and in the reporting of menopausal problems (e.g., vasomotor, psychosomatic, psychological, and urinary problems). Multivariate analyses revealed that rural-urban residential status and duration of breastfeeding of child were significant …

Rictor/Torc2 Regulates Fat Metabolism, Feeding, Growth And Life Span In C. Elegans, Alexander A. Soukas, Elizabeth A. Kane, Christopher E. Carr, Justine Melo, Gary Ruvkun

Biology Faculty Scholarship

Rictor is a component of the target of rapamycin complex 2 (TORC2). While TORC2 has been implicated in insulin and other growth factor signaling pathways, the key inputs and outputs of this kinase complex remain unknown. We identified mutations in the Caenorhabditis elegans homolog of rictor in a forward genetic screen for increased body fat. Despite high body fat, rictor mutants are developmentally delayed, small in body size, lay an attenuated brood, and are short-lived, indicating that Rictor plays a critical role in appropriately partitioning calories between long-term energy stores and vital organismal processes. Rictor is also necessary to maintain …

The One-Size-Fits-All Family, Margaret F. Brinig, Steven L. Nock

Journal Articles

Family policy and the law based on it assume universals. That is, if marriage improves the welfare of the majority of couples and their children, it is worth pushing as a policy initiative. Further, laws will be written (or kept on the books) that privilege marriage over other family forms. Similarly, research that tells us that divorce harms children except following the relatively small number of highly conflicted marriages, spawns efforts to preserve troubled marriages or even to roll back liberal or relatively inexpensive divorce laws. With yet another example, since adopted children mostly do better than children left either …

Rounding Up The Usual Suspects: A Logical And Legal Analysis Of Dna Trawling Cases, David H. Kaye

Faculty Scholarship

Courts are beginning to confront a problem that has divided the scientific community - whether identifying a defendant by fishing through a database of DNA types to find a match to a crime-scene sample reduces the significance of a match. For years, the problem seemed academic. Now that the U.S. has more than five million DNA profiles from convicted offenders and suspects in a national, computer-searchable database, the question has assumed more urgency. Increasingly, individuals are being charged with crimes as a result of a match between their recorded profile and the DNA from a victim or scene of a …
