Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Introduction: The unilateral posterior crossbite with a functional shift is one of the most common early adolescent malocclusions. It is caused by a transversely deficient maxilla, relative to the mandible, and results when the mandible shifts to one side to so the teeth can maximally interdigitate. This shift is thought to cause the contralateral condyle to move anteriorly, inferiorly, and medially within the TMJ. Much attention has been given recently to the affects of this functional shift on the condyles. An attempt is being made to determine if pathological position of the condyles can cause condylar signs or symptoms similar …

This thesis examines how the political leadership of the Soviet Union tried to cultivate its desired values and principles among the people of the Estonian Soviet Socialist Republic. It illuminates one aspect of all the ideologically charged activities, and looks at Soviet Estonian schools through the lens of compulsory reading --- how were socialist realist cultural goods used to promote Sovietization in Estonian secondary schools? Moreover, the study tries to evaluate to what degree the propagandistic intention was realized in literature lessons. Emphasis lies on exploring traces of the so-called 'double-thinking,' the notion that Estonians had the tendency to separate …
Catchment Streamflow Response To Climate Change Conditioned By Historic Alterations Of Land-Use: Forest Harvest, Succession, And Stand Conversion, David Young
Graduate Theses, Dissertations, and Problem Reports (ETD)
Forest management practices and climate change can alter streamflow in headwater catchments by changing the balance between precipitation and factors that control evapotranspiration. To understand how water resources are changing, the impacts of climate change and forest disturbance must be isolated. Toward this end the Budyko decomposition method is applied to quantify the impacts of climate change and forest disturbance on catchments of the Fernow Experimental Forest. The Budyko framework provides the theoretical basis for the methodology and assumes variation in streamflow can be attributed to the principal controls governing climate (precipitation and potential evapotranspiration) and catchment water balance (precipitation …

Effects Of Paired Housing And Acute D-Amphetamine On Delay Discounting In Lewis And Fischer 344 Rats, Marissa Turturici
Graduate Theses, Dissertations, and Problem Reports (ETD)
Lewis (LEW) and Fischer 344 (F344) rats are two genetically different strains that differ in impulsive choices made in a delay-discounting task. An operational definition of impulsive choice is a choice of a smaller-sooner reinforcer over a larger-later reinforcer. Research using LEW and F344 rats has housed rats singly. Studies have shown that paired housing influences impulsive choice, but it is not known if paired housing affects impulsive choice in the LEW and F344 strains specifically. The present study compared impulsive choice in pair-housed LEW and F344 rats to archival data from singly housed LEW and F344 rats. Impulsive choices …
Developed A Remote Technique To Assess The Effectiveness Of Thermal Insulation In Households In West Virginia, Prateek Vaish
Developed A Remote Technique To Assess The Effectiveness Of Thermal Insulation In Households In West Virginia, Prateek Vaish
Graduate Theses, Dissertations, and Problem Reports (ETD)
Physical energy audits and interventional methods cannot sustain the increasing demand of assessing the effectiveness of existing thermal insulation in households. As for now, there does not exist a sufficiently accurate remote technology or method to assess the efficiency of a thermal envelope. Usually, the energy bills and the age of the furnace are good indicators of the performance of insulation in houses. To overcome the lack of availability of a proper framework to calculate the effectiveness of the thermal envelope, a standard methodology using multiple linear regression and temperature data acquired from a house has been developed. The major …

L'Intention Mal Comprise : Les Meres Indignes De La Comtesse De Segur, Kristina Kiisk
L'Intention Mal Comprise : Les Meres Indignes De La Comtesse De Segur, Kristina Kiisk
Graduate Theses, Dissertations, and Problem Reports (ETD)
Sophie de Segur is a very well-known 19th century French children's author. Her books were and are still widely read and appreciated by children. However, she has been often criticized by literary scholars of the 20th and 21st century due to the fact that there is a lot of violence present in her novels. In addition, it has been suggested that her only goal was to educate and moralize her young readers. This opinion, however, reduces the multifaceted work of the comtesse to a purely didactic literature and we fail to recognize that her writing suggests a much deeper significance …

Low-Power And Programmable Analog Circuitry For Wireless Sensors, Brandon David Rumberg
Graduate Theses, Dissertations, and Problem Reports (ETD)
Embedding networks of secure, wirelessly-connected sensors and actuators will help us to conscientiously manage our local and extended environments. One major challenge for this vision is to create networks of wireless sensor devices that provide maximal knowledge of their environment while using only the energy that is available within that environment. In this work, it is argued that the energy constraints in wireless sensor design are best addressed by incorporating analog signal processors. The low power-consumption of an analog signal processor allows persistent monitoring of multiple sensors while the device's analog-to-digital converter, microcontroller, and transceiver are all in sleep mode. …
Refined Computational Modeling Of Sofcs Degradation Due To Trace Impurities In Coal Syngas, Hayri Sezer
Refined Computational Modeling Of Sofcs Degradation Due To Trace Impurities In Coal Syngas, Hayri Sezer
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Solid Oxide Fuel Cell (SOFC) is a good alternative for clean and efficient power generation. These cells can be operated directly on a wide variety of fuels including biogas, hydrocarbon fuels and synthesized coal gas (syngas), which is a promising avenue for utilization of coal with much less environmental impact. One of the challenges in this technology is poisoning of SOFC anodes by trace impurities contained in coal syngas. One such impurity, phosphine is known to cause catastrophic failure of SOFC anode even at <10ppm concentrations. Fuel impurity degradation patterns can vary by different operating conditions such as humidity, applied current, temperature and anode thickness.;In the present study, more detailed models are developed to predict the typical degradation behaviors observed in SOFC anode due to phosphine by extension of an in-house one-dimensional computational code. This model is first used to predict the effect of steam concentration on phosphine induced degradation in anode supported SOFCs. The model is refined based on the experimental observation, which indicate that the phosphine degradation is less severe in the absence of steam. Simulations results showed good agreement with experimental data. Then, a sensitivity analysis, using dual numbers automatic differentiation (DNAD) is performed to investigate the influence of empirical model parameters on model outputs, electrical potential, ohmic and polarization losses. Further, the refined one-dimensional model is extended to a three-dimensional model to study the phosphine induced performance degradation in relatively large planar cells operating on hydrogen fuel. The empirical model parameters are calibrated using button cell experiments and sensitivity analysis as a guide. These parameters are then used in planar cell simulations. The results from the three dimensional model show that the contaminant coverage of nickel and fuel distribution inside the anode is highly non-uniform. These non-uniform distributions are caused by the geometrical alignment of gas channels and current collectors, as well as the variation of gas concentration along the flow direction. The non-uniform deactivation of anode gave rise to the altering of current distribution inside the planar cell such that the cell can still produce current even when some regions of the anode are partially inactive. In addition, to assess the overall cell performance at any given degradation stage, additional simulations are performed to evaluate the electrochemical behavior (polarization and impedance) of the cell. The simulation results are assessed in comparison to experimental observation whenever possible. Finally, a physics based transport model for nickel migration is formulated based on experimentally observed elemental redistribution in a SOFC anode and it is integrated into refined one-dimensional phosphine degradation code. Simulations show that the proposed mechanism of Ni diffusion driven by secondary phase formation, the electrical force, and humidity can explain the experimentally observed accumulation of Ni and secondary phases on the SOFC anode surface.;Keywords: Keywords: Solid Oxide Fuel Cells, Contaminant Degradation, Automatic differentiation, Sensitivity Analysis, Impedance, Polarization, Nickel migration, Electro-migration..

Graduate Theses, Dissertations, and Problem Reports (ETD)
Stroke is the primary cause of permanent impairment and neurological damage in the United States and Europe. Annually, about fifteen million individuals worldwide suffer from stroke, which kills about one third of them. For many years, it was believed that major recovery can be achieved only in the first six months after a stroke. More recent research has demonstrated that even many years after a stroke, significant improvement is not out of reach. However, economic pressures, the aging population, and lack of specialists and available human resources can interrupt therapy, which impedes full recovery of patients after being discharged from …
