Condition Assessment Of Bill Emerson Memorial Cable-Stayed Bridge Under Postulated Design Earthquake, Dongming Yan, Wenjian Wang, Genda Chen, Bryan A. Hartnagel

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, a three-dimensional finite element model of the Bill Emerson Memorial cable-stayed bridge was developed and validated with the acceleration data recorded during the M4.1 earthquake of May 1, 2005, in Manila, Arkansas. The model took into account the geometric nonlinear properties associated with cable sagging and soil-foundation-structure interaction. The validated model was used to evaluate the performance of a seismic protective system, the behavior of cable-stayed spans, and the accuracy of two simplified bridge models that have been extensively used by the structural control community. The calculated natural frequencies and mode shapes correlated well with the measured …

Endocrine Disruptors And Obesity: An Examination Of Selected Persistent Organic Pollutants In The Nhanes 1999-2002 Data, Mai A. Elobeid, Miguel A. Padilla, David W. Brock, Douglas M. Ruden, David B. Allison

Psychology Faculty Publications

Recent evidence suggests that endocrine disrupting chemicals (EDCs) may cause perturbations in endogenous hormonal regulation that predispose to weight gain. Using data from NHANES (1999-2002), we investigated the association between body mass index (BMI), waist circumference (WC) and selected persistent organic pollutants (POPs) via multiple linear regressions. Consistent interaction was found between gender, ln oxychlordane and ln p,p' DDT. Also, we found an association between WC and ln oxychlordane and ln hpcdd in subjects with detectable levels of POPs, whereas an association between WC and ln p,p' DDT was observed in all subjects. Furthermore, ln Ocdd showed an increase with …

An Examination Of The Association Of Selected Toxic Metals With Total And Central Obesity Indices: Nhanes 99-02, Miguel A. Padilla, Mai Elobeid, Douglas M. Ruden, David B. Allison

Psychology Faculty Publications

It is conceivable that toxic metals contribute to obesity by influencing various aspects of metabolism, such as by substituting for essential micronutrients and vital metals, or by inducing oxidative stress. Deficiency of the essential metal zinc decreases adiposity in humans and rodent models, whereas deficiencies of chromium, copper, iron, and magnesium increases adiposity. This study utilized the NHANES 99-02 data to explore the association between waist circumference and body mass index with the body burdens of selected toxic metals (barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten). Some of the associations were significant direct relationships (barium and thallium), …

The Transition Zone: Impact Of Riverbanks On Emergent Dragonfly Nymphs. Implications For Riverbank Restoration And Management, Kirsten Hope Martin

Antioch University Dissertations & Theses

The use of riprap in the restoration and stabilization of riverine landscapes is an issue of concern for many ecologists. While current methods of bank stabilization, especially those involving the placement of rocks (riprap) along the waterline, are effective in controlling erosion their presence changes habitat components (slope, substrate composition, near-shore river velocity) at the river-land interface. The additional impacts of river current, water temperature, soil composition, slope, and water level fluctuation, may further imperil emerging nymphs. The purpose of this research is to document the effects of riprap, location (upriver or downriver of hydroelectric intake/outtake facilities), water level fluctuation, …

Caretakers Of The Garden Of Delight And Discontent: Adirondack Narrative, Conflict, And Environmental Virtue, Eric Richard Holmlund

Antioch University Dissertations & Theses

This dissertation concerns a widely recognized natural area, New York's Adirondack Park, that serves both as an international model for conservation and as a context for persistent conflict over natural resources, space, wealth and esthetics. It employs narrative inquiry as a method to examine the sources and the function of narratives or stories explaining the history and the present status of social groups in the Park. Narrative theorists maintain that we borrow from such socially circulating narratives to craft our own identities, and then repeat them until we believe them, almost without regard for the factual basis in history or …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

The Relationship Of Parent Involvement And Student Success In Gear Up Communities In Chicago, Wendy M. Stack

Antioch University Dissertations & Theses

Nationally, the education pipeline is not preparing enough students for success and high school dropout rates in the nation’s urban areas are alarming. This mixed methods (QUAN→qual) empirical study examines the influence of parent involvement on the academic success of 1,774 GEAR UP (Gaining Early Awareness and Readiness for Undergraduate Programs) students matched to their parents in 21 high schools in Chicago. The results of the regression analyses were presented to focus groups composed of GEAR UP parents and staff to assist in making meaning of the data and to gain deeper insight and understanding of the results. The study …

Citizen Professionals: The Effective Practices Of Experts Helping Community Organizations, Sarah Hippensteel Hall

Antioch University Dissertations & Theses

Although numerous local, state, and federal laws and policies address water pollution, many problems remain. To address these problems thousands of groups of citizens, who are concerned with their water resources - rivers, streams, lakes, ponds, and groundwater - organized around the U.S. over the past several decades. To succeed, these community organizations need the resources and capacity to reach their goals. To gain capacity, some community organizations turn to people outside the organization for assistance. Citizen professionals are helpers who work jointly with an organization to help develop an organization's adaptive capacity to deal with challenges and achieve goals. …

An Analysis Of Factors That Influence The Success Of Women Engineering Leaders In Corporate America, Letha Joye Jepson

Antioch University Dissertations & Theses

"One in 4 women entering the engineering profession leaves after age 30, while only 1 in 10 of their male counterparts does" (Perusek, 2008, p. 20). I was interested in analyzing the factors supporting women engineers’ leadership development and success. My particular focus was on women engineers in corporate environments—the personal characteristics needed for a successful career and the impacts of social support, career development, and the corporate culture on their career progression. The aspects of social support included the factors of family, friends, and significant others and the levels of supports during the woman’s career. The features of corporation …

Special Education Teacher Tenacity: The Leadership And Commitment Of Those Who Stay In The Field, Marilyn Shea

Antioch University Dissertations & Theses

Those who choose to teach special education have accepted some of the most challenging jobs teaching has to offer. Unfortunately for their students, almost half of special education teachers leave the profession within their first five years (Singer, 1992). Finding and keeping qualified special education teachers in positions working with more challenging students has become a national problem. Through qualitative interviews, this study examines the stories of 14 Colorado special educators. These teachers have demonstrated their commitment to the field by teaching for four or more years. Their stories give valuable insight into the issue of teacher commitment in difficult …

[Introduction To] When Souls Had Wings: Pre-Mortal Existence In Western Thought, Terryl Givens

Bookshelf

The idea of the pre-existence of the soul has been extremely important, widespread, and persistent throughout Western history--from even before the philosophy of Plato to the poetry of Robert Frost. When Souls Had Wings offers the first systematic history of this little explored feature of Western culture.

Terryl Givens describes the tradition of pre-existence as "pre-heaven"--the place where unborn souls wait until they descend to earth to be born. And typically it is seen as a descent--a falling away from a happier and untroubled state into the turbulent and sinful world we know. The title of the book refers to …

Tunepal: The Traditional Musician's Toolbox, Bryan Duggan

Tunepal connects musicians the scores and metadata of 13,290 traditional Irish, Welsh, Scottish and Breton dance tunes. These tunes are drawn from community sources, such as the website thesession.org and “standard” references including O’Neills Dance Music of Ireland and Brendan Breathneach’s Ceol Rince Na hÉireann series. Tunes can be retrieved by typing in a title or by playing a twelve second extract from the tune on a traditional instrument. Tunepal can be used in sitiu in …

An Empirically-Based Model For Perspective Selection In Route-Finding Dialogues, Robert J. Ross, Kavita E. Thomas

Conference papers

In this work we aim to computationally model the extent to which certain empirical factors affect spatial perspective selection as used in route-finding dialogues. In such dialogues, both interlocutors need to adopt a spatial perspective in which to describe movement direction. In map-based tasks such as the one we are concerned with, two perspective choices are typically available, i.e., route perspective, where projective terms are defined with respect to the perspective of the route follower themselves, e.g., ``go to your right'', or survey perspective, where projective terms are defined with respect to a global or allocentric perspective, e.g., ``go down'', …

Physiological Responses To Temperature In The Lizard, Sceloporus Undulatus, Joseph C. Ehrenberger

All-Inclusive List of Electronic Theses and Dissertations

Temperature affects all organisms differently. Physiological processes, such as metabolism, interact with temperature to determine a minimal rate of energy loss. Physiological limits, such as heat and cold tolerances, likely constrain the activity and survival of organisms. Ultimately, these physiological processes and limits determine a species' geographical distribution. Through experiments, I sought to understand specifically how temperature affects the physiology of the lizard Sceloporus undulatus. This species is a model organism to answer such questions, as it is geographically widespread species and well-described phylogenetically. In the first experiment, I compared standard metabolic rates of lizards from three locales and interpreted …

Social Class Experiences Of Working-Class Students: Transitioning Out Of College, Huber Carey Treager

All-Inclusive List of Electronic Theses and Dissertations

Issues surrounding social class are often overlooked and rarely discussed in higherEducation; however, they affect students and institutions in critical ways. Although research has demonstrated that social class is a predictor of access to college, retention, academic performance, overall undergraduate and graduate experience, and college completion, little is known about the effect of social class on students' transition out of college and into the workplace. This transition is critical to explore because research suggests that the way in which students approach their first years of work have an impact on future job success and satisfaction. A phenomenological method of inquiry …

A Survey Of Transition Strategies To Improve The Performance Of Chord In The Face Of Rapidly Changing Ip Addresses, Timothy Ecklund

Theses

Mobile wi-fi enabled devices are becoming less expensive and more common all the time. The field is ripe for DHTs like Chord. Given the highly scalable nature of DHTs, the ability to efficiently tap the storage resources of so many devices is very attractive. Unfortunately DHTs have been having a difficult time finding a foothold on mobile devices due to poor performance, both in terms of network overhead and lookup failure. Much of the research that has been done attributes this poor performance to the extra hops packets must make due to the mismatch between the physical topology and the …

Theory Of Island Biogeography On A Microscopic Scale: Organic Aggregates As Islands For Aquatic Pathogens, M. M. Lyons, J. E. Ward, Holly Gaff, R. E. Hicks, J. M. Drake, Fred C. Dobbs

OES Faculty Publications

Four predictions of the MacArthur-Wilson theory of island biogeography were evaluated to assess the degree to which detrital-based organic aggregates (e.g. marine snow, organic detritus, and bioflocs) may provide a favorable microhabitat (i.e. an 'island') for bacteria in general, and specifically aquatic pathogens. We demonstrate the theory's relevance for microbial communities in aquatic environments by describing the community metabolic response and functional diversity of individual organic aggregates while documenting the persistence of potential pathogens and fecal indicator bacteria. Our results support the 4 predictions, including a significant species-area relationship, consistency of species richness at equilibrium, non-zero level of species turnover …

Benthic Ecology From Space: Optics And Net Primary Production In Seagrass And Benthic Algae Across The Great Bahama Bank, Heidi M. Dierssen, Richard C. Zimmerman, Lisa A. Drake, David J. Burdige

OES Faculty Publications

Development of repeatable and quantitative tools are necessary for determining the abundance and distribution of different types of benthic habitats, detecting changes to these ecosystems, and determining their role in the global carbon cycle. Here we used ocean color remote sensing techniques to map different major groups of primary producers and estimate net primary productivity (NPP) across Great Bahama Bank (GBB). Field investigations on the northern portion of the GBB in 2004 revealed 3 dominant types of benthic primary producers: seagrass, benthic macroalgae, and microalgae attached to sediment. Laboratory measurements of NPP ranged from barely net autotrophic for grapestone sediment …

A Seasonal Study Of Dissolved Cobalt In The Ross Sea, Antarctica: Micronutrient Behavior, Absence Of Scavenging, And Relationships With Zd, Cd, And P., M. A. Saito, T. J. Goepfert, A. E. Noble, E. M. Bertrand, Peter N. Sedwick, Giacomo R. Ditullio

OES Faculty Publications

We report the distribution of cobalt (Co) in the Ross Sea polynya during austral summer 2005-2006 and the following austral spring 2006. The vertical distribution of total dissolved Co (dCo) was similar to soluble reactive phosphate (PO(4)(3-)), with dCo and PO(4)(3-) showing a significant correlation throughout the water column (r(2) = 0.87, 164 samples). A strong seasonal signal for dCo was observed, with most spring samples having concentrations ranging from similar to ~ 45-85 pM, whereas summer dCo values were depleted below these levels by biological activity. Surface transect data from the summer cruise revealed concentrations at the low range …

Determination Of Total Dissolved Cobalt In Uv-Irradiated Seawater Using Flow Injection With Chemiluminescence Detection, Rachel U. Shelley, Bernhard Zachhuber, Peter N. Sedwick, Paul J. Worsfold, Maeve C. Lohan

OES Faculty Publications

A sensitive flow-injection method with chemiluminescence detection (FI-CL) for the determination of dissolved cobalt in open ocean samples, suitable for shipboard use has been developed. To date, FI methods for dissolved cobalt have been used only in coastal and estuarine waters. Therefore, significant modifications to existing methods were required, including (1) the use of a commercially available iminodiacetate (IDA) resin (Toyopearl AF-chelate 650M) in place of resin immobilized 8-hydroxyquinoline for online preconcentration and matrix removal, (2) the introduction of acidified ammonium acetate (pH 4) as a column-conditioning step before sample loading and rinse steps, and most importantly, (3) UV irradiation …

On The Fractional Solubillity Of Copper In Marine Aerosols: Toxicity Of Aeolian Copper Revisited, Edward R. Sholkovitz, Peter N. Sedwick, Thomas M. Church

OES Faculty Publications

Paytan et al. (2009) argue that the atmospheric deposition of aerosols lead to copper concentrations that are potentially toxic to marine phytoplankton in a large area of tropical and subtropical North Atlantic Ocean. A key assumption in their model is that all marine aerosols (mineral dust and anthropogenic particles) have a high (40%) fractional solubility of copper. Our data show that the fractional solubility of copper for Saharan dust over the Sargasso Sea and Bermuda is significantly lower (1-7%). In contrast, anthropogenic aerosols with non-Saharan sources have significantly higher values (10-100%). Hence, the potential Cu toxicity in the tropical and …

Determination Of Ceftriaxone, Ceftizoxime, Paracetamol, And Diclofenac Sodium By Capillary Zone Electrophoresis In Pharmaceutical Formulations And In Human Blood Serum, Amber Solangi, Saima Memon, Arfana Mallah, Najma Memon, Muhammad Yar Khuhawar, Muhammad Iqbal Bhanger

Turkish Journal of Chemistry

A simple and fairly fast capillary zone electrophoresis method has been developed for the determination and separation of ceftriaxone, ceftizoxime, paracetamol, and diclofenac sodium in a mixture, in pharmaceutical formulations, and in blood serum. A 50 mM sodium tetraborate background electrolyte solution (pH 9.0) was found to be suitable for separation of all the drugs. An uncoated fused-silica capillary of a total length of 57 cm (effective length 50 cm) was used for separation. All the analytes were completely separated within 8.0 min at an applied voltage of 30 kV and detection was performed at 214 nm .Validation of the …

Building Sustainable Societies: Exploring Sustainability Policy And Practice In The Age Of High Consumption, Cindy Isenhour

University of Kentucky Doctoral Dissertations

This dissertation is an attempt to examine how humans in wealthy, post-industrial urban contexts understand sustainability and respond to their concerns given their sphere of influence. I focus specifically on sustainable consumption policy and practice in Sweden, where concerns for sustainability and consumer-based responses are strong. This case raises interesting questions about the relative strength of sustainability movements in different cultural and geo-political contexts as well as the specific factors that have motivated the movement toward sustainable living in Sweden.

The data presented here supports the need for multigenic theories of sustainable consumerism. Rather than relying on dominant theories of …

Real-Time Model Predictive Control Of Quasi-Keyhole Pipe Welding, Kun Qian

University of Kentucky Doctoral Dissertations

Quasi-keyhole, including plasma keyhole and double-sided welding, is a novel approach proposed to operate the keyhole arc welding process. It can result in a high quality weld, but also raise higher demand of the operator. A computer control system to detect the keyhole and control the arc current can improve the performance of the welding process. To this effect, developing automatic pipe welding, instead of manual welding, is a hot research topic in the welding field.

The objective of this research is to design an automatic quasi-keyhole pipe welding system that can monitor the keyhole and control its establishment time …

Palinspastic Reconstruction Around A Thrust Belt Recess: An Example From The Appalachian Thrust Belt In Northwestern Georgia, Brian Stephen Cook

University of Kentucky Doctoral Dissertations

In a well-defined subrecess in the Appalachian thrust belt in northwestern Georgia, two distinct regional strike directions intersect at approximately 50°. Fault intersections and interference folds enable tracing of both structural strikes. Around the subrecess, tectonically thickened weak stratigraphic layers—shales of the Cambrian Conasauga Formation—accommodated ductile deformation associated with the folding and faulting of the overlying Cambrian–Ordovician regional competent layer. The structures in the competent layer are analogous to those over ductile duplexes (mushwads) documented along strike to the southwest in Alabama.

The intersection and fold interference exemplify a long-standing problem in volume balancing of palinspastic reconstructions of sinuous thrust …

Measurement Of Single-Target Spin Asymmetries In The Electroproduction Of Negative Pions In The Semi-Inclusive Deep Inelastic Reaction N↑(E,Éπ¯)X On A Transversely Polarized 3he Target, Chiranjib Dutta

University of Kentucky Doctoral Dissertations

The experiment E06010 measured the target single spin asymmetry (SSA) in the semiinclusive deep inelastic (SIDIS) n↑(e,éπ¯)X reaction with a transversely polarized ³He target as an effective neutron target. This is the very first independent measurement of the neutron SSA, following the measurements at HERMES and COMPASS on the proton and the deuteron. The experiment acquired data in Hall A at Jefferson Laboratory with a continuous electron beam of energy 5.9 GeV, probing the valence quark region, with x = 0.13→0.41, at Q² = 1.31→3.1 GeV². The two contributing mechanisms to the measured asymmetry, viz, the …
