Stand Dynamics And Disturbance History Of Five Oak -Dominated Old -Growth Stands In The Unglaciated Appalachian Plateau, James Spencer Rentch
Graduate Theses, Dissertations, and Problem Reports
Stand dynamics and disturbance histories of five eastern, oak-dominated old-growth stands were investigated using ecological field sampling techniques, dendrochronologogical methods, and a review of historical resources of original forest composition and patterns of human and natural disturbance. Witness tree tallies from 18th century land surveys show that presettlement forests in the study areas were oak-dominated forests. Quercus alba was, at minimum, twice as abundant as Q. velutina, the second ranked species. Acer saccharum and Fagus grandifolia were among the top ten ranked species at each site; however their importance value was consistently less than one-third the value for Q. alba. …

Use of wood composite products has increased over the last decade in the market for construction material. Softwood species and soft hardwood species are the preferred forest resources for manufacturing these products. Reduction in available softwood forest resources from the Western states has forced a shift to use of more soft hardwood species in the Northeast. What impact this shift may have on the forest resources in the Northeast is not known.;The objective of this study was to canvass primary wood manufacturers in and around the forest of West Virginia and determine how roundwood consumption has changed since the shift …
Toward High-Definition Reservoir Characterization, Gheorghe Luca
Toward High-Definition Reservoir Characterization, Gheorghe Luca
Graduate Theses, Dissertations, and Problem Reports
A new methodology for high resolution reservoir characterization is proposed. It combined the advantages of the surface seismic (low resolution, large coverage) and crosswell seismic (improved resolution, small coverage).;The process involves deconvolution of a low resolution signal (surface seismic traces) into a high resolution crosswell seismic trace. The problem has multiple solutions and an analytical solution is hard or difficult to be developed.;This project proved that it is possible to predict high-resolution crosswell seismic traces using low-definition surface seismic traces. The statistical comparison between the real and the synthetic crosswell seismic traces gives confidence that future work in this area …
Parent-Infant Interactions During Acute Painful Procedures, Catherine Bradford Mcclellan
Parent-Infant Interactions During Acute Painful Procedures, Catherine Bradford Mcclellan
Graduate Theses, Dissertations, and Problem Reports
Despite the current recognition of infant procedural pain and distress, there is a dearth of research, both in the assessment and treatment literature, of infant procedural distress. This study examined how specific parent behaviors relate to infant procedural distress and whether this relation is mediated by birth order. Results indicated that females were rated as more distressed than were males, and that birth order did not prove to be a distinguishing factor in infant distress. Finally, while some behaviors appear to have a similar influence on both preschoolers' and infants' behaviors, parents' behavior during infants' distressing procedures were found to …

Prenatal Stress Alters Fear-Conditioned Behaviors And The Response To Serotonergic Drugs, William C. Griffin Iii
Prenatal Stress Alters Fear-Conditioned Behaviors And The Response To Serotonergic Drugs, William C. Griffin Iii
Graduate Theses, Dissertations, and Problem Reports
Chronic, inescapable stress during pregnancy (i.e. prenatal stress) modifies the behavior of the adult offspring. Several behaviors were evaluated in adult prenatally stressed (PS) rats, most notably the acoustic startle response and behavioral inhibition (i.e. freezing). PS rats do not differ in baseline peak startle responding, or in the habituation of the peak startle response when compared to the non-prenatally stressed (CON) rats. However, PS rats have greater peak responses and longer latencies to reach the peak response following systemic doses of the 5-HT 1A agonist, 8-OH-DPAT, compared to CON rats. The PS rats had shorter latencies than the CON …
Psychometric Properties Of The Social Interactions Questionnaire (Siq) In An Older Adult Sample, Kimberly Debra Kalish
Psychometric Properties Of The Social Interactions Questionnaire (Siq) In An Older Adult Sample, Kimberly Debra Kalish
Graduate Theses, Dissertations, and Problem Reports
This study examined the psychometric properties of the Social Interactions Questionnaire (SIQ; Kalish & Edelstein, 1996), a quick and efficient tool to measure negative social interactions. Overwhelming evidence has emerged over the past decade indicating that negative social interactions (NSIs) are strongly related to measures of mental and physical health. A critique of existing measures of NSIs reveals long and cumbersome interviews that are comprised of some, but not all, of the critical elements of NSIs. The SIQ efficiently measures these critical elements, which include (a) perceived versus structural components of NSIs, (b) seven different types of NSIs, (c) overall …

Women And Physical Culture In Modern Poland, Nameeta Mathur
Graduate Theses, Dissertations, and Problem Reports
This dissertation examines the interaction between the various forces of Polish "nationalism" and "feminism" in the construction of women's physical culture in modern Poland from the late nineteenth century until the end of the twentieth century. The basic premise of this work is that unlike most western countries where sportswomen have typically been marginalized in their athletic endeavors, Polish female athletes have earned far greater respect and recognition in the development of their physical culture. On many occasions, women's athleticism in Poland was a source of immense pride and prestige for both the state and society, albeit for varied reasons …
Transfer Of Heart Rate Feedback Training To Reduce Heart Rate Response To Laboratory Tasks, Jeffrey Louis Goodie
Transfer Of Heart Rate Feedback Training To Reduce Heart Rate Response To Laboratory Tasks, Jeffrey Louis Goodie
Graduate Theses, Dissertations, and Problem Reports
Researchers have demonstrated that individuals can successfully reduce their heart rate (HR) response to a stressor when provided with heart rate feedback. However, it is unclear whether individuals can transfer HR reduction skills to stressors not used during HR feedback training. The present study used a multiple baseline, single subject design to examine the transfer of HR feedback training among six individuals. Participants were provided with HR feedback training during the presentation of a videogame, a mental arithmetic challenge, and a hand grip task until the participants reduced their HR to within 4 bpm of their resting HR or until …
Multifractal Analysis Of Memory Usage Patterns, Jonathan Browning Crowell
Multifractal Analysis Of Memory Usage Patterns, Jonathan Browning Crowell
Graduate Theses, Dissertations, and Problem Reports
The discovery of fractal phenomenon in computer-related areas such as network traffic flow leads to the hypothesis that many computer resources display fractal characteristics. The goal of this study is to apply fractal analysis to computer memory usage patterns. We devise methods for calculating the Holder exponent of a time series and calculating the fractal dimension of a plot of a time series. These methods are then applied to memory-related data collected from a Unix server. We find that our methods for calculating the Holder exponent of a time series yield results that are independently confirmed through calculation of the …

Improved Velocity Data In Circular Jets Using An Avalanche Photodiode-Based 2-Component Point Doppler Velocimeter, Thomas Trent Scarberry
Improved Velocity Data In Circular Jets Using An Avalanche Photodiode-Based 2-Component Point Doppler Velocimeter, Thomas Trent Scarberry
Graduate Theses, Dissertations, and Problem Reports
An existing Point Doppler Velocimeter (pDv) has been modified in an effort to improve the RMS velocity results. Improvements have been made by reducing the probe volume size by focusing the incident laser beam, thereby reducing the effects of spatial averaging on the mean and RMS velocity measurements.;In particular, the PIN photodetectors used previously, were tested using the reduced probe volume, and were then replaced by high-gain, high signal-to-noise ratio large area avalanche photodetectors (APD's).;Comparisons have been made between the data acquired and hot wire data obtained on the same jet flow, as well as data obtained in previous pDv …
Parent Distress, Parent Behavior, And Infant Distress During Pediatric Immunizations, Rebecca Suzanne Bernard
Parent Distress, Parent Behavior, And Infant Distress During Pediatric Immunizations, Rebecca Suzanne Bernard
Graduate Theses, Dissertations, and Problem Reports
Infant procedural distress historically has been ignored, and the importance of reducing infant distress only recently has been addressed. To understand and manage infant procedural distress, it is essential to examine the correlates and potential predictors of this distress. The purpose of this study was to examine the effects of parent distress on infant procedural distress, the effects of parent behavior on infant distress, and the combined impact of parent distress and behavior on infant distress for 37 parent-infant dyads. Results demonstrated that infant measures were not intercorrelated, only parent self-report measures were intercorrelated, and several measures of parent distress …

Mechanisms Of Retroviral Replication, Timur O. Kabdulov
Mechanisms Of Retroviral Replication, Timur O. Kabdulov
Graduate Theses, Dissertations, and Problem Reports
Specific encapsidation of viral RNA is an essential step of retroviral replication cycle. Extensive biochemical and genetic analyses suggest that majority of retroviruses employ similar mechanisms for specific RNA packaging. Better understanding of mechanisms of this process may help to develop new anti-retroviral drugs against such serious pathogens as human immunodeficiency virus types 1 and 2.;This study concerns with specific packaging of RNA by two simple retroviruses, murine leukemia virus (MLV) and spleen necrosis virus (SNV). SNV proteins can package RNA of both SNV and MLV with similar efficiency. In contrast, MLV proteins cannot package SNV RNA. NC domain was …
Order Effects Of Fear And Pain Induction, Kevin Erik Vowles
Order Effects Of Fear And Pain Induction, Kevin Erik Vowles
Graduate Theses, Dissertations, and Problem Reports
Although pain responding and emotional states such as fear are highly correlated and appear to interact, the causal relations between these variables have yet to be fully defined. This study sought to further illuminate these relations by investigating how exposure to one of these states (i.e., pain or fear) affects responding to the other. The order in which participants experienced fearful or painful stimuli was manipulated, as well as fear level (i.e., "low" & "high"). Measures of behavioral escape, heart rate, and verbal reports were obtained throughout four experimental trials, as well as rankings of aversiveness for all stimuli encountered. …

In the first part an algorithm for the design of nonlinear decentralized excitation control is developed based on a feedback linearization technique. Feedback linearization technique is applied in excitation control of each generator to obtain an interconnected system where subsystems have linear system matrices and interconnections are represented by nonlinear terms. Different ways of achieving decentralization are investigated: (1) linear robust control combined with observer decoupled state space; (2) disturbance accommodation control. …
Dutch Women In New Netherland And New York In The Seventeenth Century, Michael Eugene Gherke
Dutch Women In New Netherland And New York In The Seventeenth Century, Michael Eugene Gherke
Graduate Theses, Dissertations, and Problem Reports
The European settlers who emigrated to America in the seventeenth century were decidedly patriarchal. Nevertheless, significant cultural differences in expressions of patriarchy among them existed. Specifically, the Dutch of New Netherland defined the gendered roles of women differently than did other European cultures. More than deputy-husbands, but less than full partner, seventeenth-century Dutch women in New Netherland were integral to the survival and promotion of their families' interests and preservation of the colony. English expropriation of New Netherland in 1664 and permanent acquisition in 1674 inaugurate a process of patriarchal acculturation that over time submerged the roles of Dutch women. …
Factors Affecting Cyp2c9-Mediated Metabolism, James Matthew Hutzler
Factors Affecting Cyp2c9-Mediated Metabolism, James Matthew Hutzler
Graduate Theses, Dissertations, and Problem Reports
Cytochrome P450 enzymes can exhibit non-Michaelis-Menten, or atypical kinetics. In particular, dapsone activates CYP2C9-mediated flurbiprofen 4 '-hydroxylation. However, the mechanism of activation of CYP2C9 is poorly understood. The activation of flurbiprofen, naproxen, and piroxicam metabolism by dapsone was investigated, fitting kinetic data to a two-site effector model, indicating that the CYP2C9 active site may have multiple binding regions. In addition the structural requirements for activation of CYP2C9 were explored using structural analogs of dapsone, with results suggesting that a sulfone group between two benzene rings is necessary for activation. CYP2C9 *2(R144C) and *3(I359L) allelic variants and the F114L mutant enzymes …
Optical Gradation For Crushed Limestone Aggregates, Ken Cheng
Optical Gradation For Crushed Limestone Aggregates, Ken Cheng
Graduate Theses, Dissertations, and Problem Reports
The strength and durability of asphalt pavement is directly affected by the characteristics of its main ingredient, mineral aggregate. Besides material strength, research has shown that mixture properties such as particle shape and mixture gradation have a significant affect on the quality of the asphalt concrete. A standard called "Superpave" has been developed which sets forth specifications for material selection and methods for measurement of aggregate properties. These standards require monitoring of aggregate properties, particularly gradation. In this dissertation, the feasibility of developing an optically based method for determining aggregate gradation was explored. The physical system primarily consists of a …
Study Of The Rheological Properties Of Nomex Fibrids, Long Han
Study Of The Rheological Properties Of Nomex Fibrids, Long Han
Graduate Theses, Dissertations, and Problem Reports
Paints and caulks typically contain (spherical) fumed silica particulates as viscosity enhancers. A similar viscosity enhancement can be achieved by using aramid fibrids. Aramid fibrids are believed to form microstructures in suspensions because of the "space-filling" nature of their shapes and thus provide a convenient means of introducing desired rheological behavior for various commercial applications.;The flow responses of aramid fibrids dispersed in mixtures of corn syrup and water were determined in dynamic shear, steady shear, low shear capillary, and extensional stretching flows. Yield stress, strong shear thinning, thixotropy, and strong dispersion effects were observed, and these are consistent with observed …
Studies Of The Mammalian Ovarian Endothelin System, Marietta Felicidad Wright
Studies Of The Mammalian Ovarian Endothelin System, Marietta Felicidad Wright
Graduate Theses, Dissertations, and Problem Reports
In porcine ovaries, endothelin-1 (ET-1) may have an autocrine/paracrine role in follicular development. Endothelin-converting enzyme-1 (ECE-1) converts big endothelin-1 to ET-1. In situ hybridization was used to determine the ovarian compartment that synthesizes ECE-1. ECE-1 mRNA was detected in granulosa cells of large (10 mm) and medium (3 mm) antral follicles. This study, in conjunction with previous studies suggests a novel autocrine role of ET-1 as a possible local ovarian factor of follicular development. ET-1 may play a role during prostaglandin (PG) F2 alpha-induced luteal regression in the cow. Effects of PGF2 alpha treatment were examined during early and mid-luteal …
