Climate-Induced Changes In The Germination Phenology Of Boechera Stricta, Samuel Johnson Dec 2014

Climate-Induced Changes In The Germination Phenology Of Boechera Stricta, Samuel Johnson

Theses and Dissertations

Climate change is having demonstrable, worldwide impacts on ecological systems in ways that have modified aspects of organism behavior. Plant phenologies have responded to warmer temperatures in a variety of ways that may have implications for long-term species survival. How germination phenology changes in response to warmer climate is a largely unexplored question yet the ability of a plant to advance or delay germination in unfavorable conditions is critical for survival. Knowing the relative success and timing of germination under different climate regimes is important in understanding whether species can keep pace with the rate of climate change via migration …

Gender Influenced Social Welfare Reforms At The South Carolina Confederate Soldiers’ Home And Infirmary: An Institutional History (1908 - 1957), Brian Dolphin

Theses and Dissertations

The South Carolina Confederate Soldiers’ Home and Infirmary in Columbia opened in 1909, serving two aged and infirm veterans per county. The last former Confederate state to establish a residential facility for veterans, South Carolina became the first state to reserve positions for women on the managing board. Women on the Board exercised more power there than at any comparable institution in the South, with policy implications that featured an increasingly inclusive policy for accommodation of women as both Confederate Soldiers’ Home and Infirmary administrators and occupants. When the institution closed in 1957, it had cared for women for a …

Finite Element Analysis Simulations Of Micro And Nano-Electromechanical Sensors For Design Optimization, Nicholas Frank Deroller Dec 2014

Finite Element Analysis Simulations Of Micro And Nano-Electromechanical Sensors For Design Optimization, Nicholas Frank Deroller

Theses and Dissertations

Micro and Nano-electromechanical sensors (MEMS and NEMS) provide a means of actively sensing minute changes in the surrounding environment. Small changes in temperature, momentum, and strain may be sensed in passive modes while greater sensing possibilities exist in active modes. Theoretical femto-gram resolution mass detection and heated element sensing methods may be used while volatile organic compound (VOC) sensing may be achieved when combined with a functionalization layer or device heating. These devices offer a great reduction in cost and offer increased mobility by allowing a "lab-on-chip" solution for the prospective user while also greatly reducing the amount of energy …

Design And Development Of A Novel Class Of Cell Cycle Cdk Inhibitors Targeting The Cyclin Binding Groove Utilizing The Replace Strategy, Padmavathy Nandha Premnath Dec 2014

Design And Development Of A Novel Class Of Cell Cycle Cdk Inhibitors Targeting The Cyclin Binding Groove Utilizing The Replace Strategy, Padmavathy Nandha Premnath

Theses and Dissertations

Inhibition of CDK2 activity in G1 and S phases of the cell cycle can promote selective apoptosis of cancer cells through the E2F1 pathway. Currently available CDK inhibitors target the ATP binding pocket and result in lack of specificity for the cell cycle vs. the transcriptional CDKs. It has been shown that a peptide HAKRRLIF derived from the tumor suppressor p21 binds to the cyclin binding groove (CBG) and selectively inhibits cell cycle CDKs (CDK2/Cyclin A, CDK2/Cyclin E and CDK4/Cyclin D). The CBG is unique to cell cycle CDKs hence targeting this site avoids the inhibition of transcriptional CDKs can …

Synthetic Physical Models For Animating Unsteady Fish Motions, Shyh-Kuang Ueng, Hong-Kai Chen Dec 2014

Synthetic Physical Models For Animating Unsteady Fish Motions, Shyh-Kuang Ueng, Hong-Kai Chen

Journal of Marine Science and Technology–Taiwan

This paper presents physical models for simulating unsteady fish motions, including bursting, gliding, braking, turning, ascending and descending. A new wave model, the controllable body wave model, is developed to undulate the fish body to produce bursting and gliding motions. A key frame approach is adopted to realize braking, turning, descending and ascending. In the key frame method, individual motions are decomposed into sequences of key steps. The gestures of the fish in these key steps are recorded and regarded as key frames. In the run time, these recorded key frames are sequentially reproduced to generate swimming patterns. In addition …

Fabrication And Characterization Of Novel Electrodes For Solid Oxide Fuel Cell For Efficient Energy Conversion, Yu Chen Dec 2014

Fabrication And Characterization Of Novel Electrodes For Solid Oxide Fuel Cell For Efficient Energy Conversion, Yu Chen

Theses and Dissertations

Solid oxide fuel cells (SOFCs) have been considered as one of the most promising technologies for future energy conversion since they can in principle be operated with fuels ranging from H2 to any hydrocarbon fuel. However, the system cost and coking (when using hydrocarbon as fuel) issues for the state-of-art electrode materials/designs often limit their further application. The objective of this Ph.D dissertation is aiming at overcoming these problems and accelerating SOFC commercialization. One approach to cost reduction is lowering the SOFC operating temperature to below 800 or even 600 oC, so that inexpensive materials can be used and quick …

Characterization Of Electrodeposited Copper Foil Surface Roughness For Accurate Conductor Power Loss Modeling, Michael B. Griesi Dec 2014

Characterization Of Electrodeposited Copper Foil Surface Roughness For Accurate Conductor Power Loss Modeling, Michael B. Griesi

Theses and Dissertations

As computer data rates have increased, designers observed that the standard models for estimating the impact of copper foil surface roughness on conductor loss are limited to a few GHz. The more recent snowball model (a “snowball” estimation of the Huray Model) has demonstrated improved conductor loss predictions up to 50 GHz by estimating the necessary parameters using reasonable assumptions about the geometric surface features of electrodeposited copper foil. Since then, the Huray Model has been incorporated into commercial electromagnetic field simulators. However, a standard method of characterizing the electrodeposited copper foil used in high-speed circuits to directly implement the …

Comprehensive Joint Time-Frequency Analysis Toward Condition Based Maintenance Regimes For Electrical And Mechanical Components, David Lee Coats Dec 2014

Comprehensive Joint Time-Frequency Analysis Toward Condition Based Maintenance Regimes For Electrical And Mechanical Components, David Lee Coats

Theses and Dissertations

Based upon a framework of time-frequency analysis, we outline condition based maintenance (CBM), or maintenance only upon evidence of need, for both electrical and mechanical systems. We apply novel time-frequency cross-correlation metrics to helicopter drivetrain systems and electrical cables as remaining useful life assessments by non-destructive and non-invasive tests. In both cases, these metrics for health assessment provide a basis for diagnostic and prognostic analysis of underlying systems and components by performing accelerated condition tests on actual mechanical and electrical systems. We present novel time-frequency domain vibration analysis of a gearbox failure in an AH-64 Apache drivetrain testbed and quantify …

A Theory Of Reward Stability, Justice Evaluations And Group Cooperation, Hyomin Park Dec 2014

A Theory Of Reward Stability, Justice Evaluations And Group Cooperation, Hyomin Park

Theses and Dissertations

The objective of this dissertation is to introduce a theory of the stability of rewards, justice evaluations and group cooperation with the results from three empirical tests of the theory. According to justice theory, rewards from exchange relations produce justice evaluations among individuals, leading to emotional and behavioral reactions. Specifically, unjust rewards cause lower levels of justice evaluations, positive emotions, and cooperative behaviors. Prospect theory and research on negativity bias posit the asymmetry between negative and positive events: negative events have a stronger effect than the same size of positive events on individuals’ perception. Combining the previous arguments, the theory …

Measurement Of Polarization Observables PZ, PSZ, And PCZ In Double-Pion Photoproduction Off The Proton, Yuqing Mao Dec 2014

Measurement Of Polarization Observables PZ, PSZ, And PCZ In Double-Pion Photoproduction Off The Proton, Yuqing Mao

Theses and Dissertations

Meson production from excited nucleons is important in the study of baryon resonances and pion photoproduction is attracting much attention. To date a rather large amount of unpolarized cross-section measurements have been reported for both single- and double-pion photoproduction. However, polarization observables provide complementary information as they probe different combinations of transition amplitudes. The database for polarization observables remains quite sparse. Double-pion photoproduction have been studied in Hall B at Jefferson Lab with linearly polarized tagged photon beams incident on longitudinally polarized protons. The experiment covered center-of-mass energies between 1.4 GeV and 2.3 GeV. The target was a FROzen Spin …

Toward A Theory Of Safe Passage: Agentic Practices Of Women Writers Who Teach, Lillian Gordon Reeves Dec 2014

Toward A Theory Of Safe Passage: Agentic Practices Of Women Writers Who Teach, Lillian Gordon Reeves

Theses and Dissertations

Past studies show that narrative is an effective tool for guiding teachers to develop teacher identity, to recognize their practical knowledge, and to engage in teacher transformation, especially during initial teacher training and the early years of their career. Consequently, other researchers have identified how narrative studies inform what we know about teachers’ identities, their practical knowledge, and their transformations during initial training and early career teaching. However, we do not know how narrative functions in the experiences of teachers beyond initial teacher training and early career teaching. This study intends to fill this gap in the research. In this …

Essays On Battle Clusters In Internal Armed Conflicts And Insurgencies: Concept, Causes And Consequences, Chifeng Liu Dec 2014

Essays On Battle Clusters In Internal Armed Conflicts And Insurgencies: Concept, Causes And Consequences, Chifeng Liu

Theses and Dissertations

With the purpose to re-conceptualize the intensity of internal armed conflicts, I argue that the characteristics such as location, scale and duration of “major battlefields,” i.e. the spatio-temporal clusters of combat events are important in the evaluation of impact of modern civil wars and insurgencies. I start with elaborating and constructing a new concept of conflict magnitude with battle clusters using up-to-date geo-referenced data and spatial statistic methods. In the second article, I first explain the location and duration of major battlefields. The findings indicate that an area with multiple non-state armed groups (NSAGs) is more likely to become main …

Task-Specific Human Capital Accumulation And Wage Outcomes Among Young Men: An Empirical Analysis, Morgan Holland Dec 2014

Task-Specific Human Capital Accumulation And Wage Outcomes Among Young Men: An Empirical Analysis, Morgan Holland

Theses and Dissertations

Existing literature suggests that investment in different kinds of task-specific human capital may have significant effects on wage outcomes and overall economic wellbeing of individuals. To examine this claim, the accumulation of task-specific human capital in young male workers with no college education and its effects on wages is measured. Using National Longitudinal Survey of Youth panel data merged with six task-specific human capital measures derived from the Dictionary of Occupational Titles task contents data, fixed effects regression was utilized to measure how workers’ taskspecific human capital develops over time. This process shows that among the task measures used, accumulation …
