Fundamental Properties Of Functional Zinc Oxide Nanowires Obtained By Electrochemical Method And Their Device Applications, Athavan Nadarajah

Dissertations and Theses

We report on the fundamental properties and device applications of semiconductor nanoparticles. ZnO nanowires and CdSe quantum dots were used, prepared, characterized, and assembled into novel light-emitting diodes and solar cells. ZnO nanowire films were grown electrochemically using aqueous soluble chloride-based electrolytes as precursors at temperatures below 90° C. Dopants were added to the electrolyte in the form of chloride compounds, which are AlCl₃, CoCl₂, CuCl₂, and MnCl₂. The optical, magnetic, and structural properties of undoped and transition-metal-ion doped ZnO nanowires were explored. Our results indicate that the as-grown nanowire structures have …

Designing New Drugs To Treat Cardiac Arrhythmia, Yanping Ye

Dissertations and Theses

Heart failure resulting from different forms of cardiomyopathy is defined as the inability of the heart to pump sufficient blood to meet the body's metabolic demands. It is a major disease burden worldwide and the statistics show that 50% of the people who have the heart failure will eventually die from sudden cardiac death (SCD) associated with an arrhythmia. The central cause of disability and SCD is because of ventricular arrhythmias. Genetic mutations and acquired modifications to RyR2, the calcium release channel from sarcoplasmic reticulum, can increase the pathologic SR Ca2+ leak during diastole, which leads to defects in SR …

Heart Rate And Accelerometry During Singles Footbag Net Play, Christopher Michael Siebert

Dissertations and Theses

This investigation examined the heart rate responses and movement characteristics of experienced footbag net players during singles play. Footbag net is a net/court sport similar to volleyball, but it is played with a footbag (e.g., Hacky-Sack^TM) using only the feet. In singles footbag net, players are allowed either one or two kicks to propel the footbag over the net. Subjects were 15 males and 1 female, ranging in age from 18- 60 years, with a mean age of 33.6 years.

The sample consisted of 380 SAGE patients who had continuous enrollment in 2005. These patients formed the cohort for the study. Agency records for these …

Origin Of Surface Undulations At The Kamb Ice Stream Grounding Line, West Antarctica, Fiona Bronwyn Seifert

Dissertations and Theses

The West Antarctic Ice Sheet is drained primarily by five major ice streams, which together control the volume of ice discharged into the ocean across the grounding line. The grounding line of Kamb Ice Stream (KIS) is unusual because the ice stream upstream of it is stagnant. Here, a set of surface features--shore-parallel, long wavelength, low amplitude undulations--found only at that grounding line are examined and found to be "pinch and swell" features formed by an instability in the viscous deformation of the ice. When a relatively competent layer is surrounded by lower strength materials, particular wavelength features within the …

Brown Abroad: An Empirical Analysis Of Foreign Judicial Citation And The Metaphor Of Cosmopolitan Conversation, Sheldon B. Lyke

Vanderbilt Journal of Transnational Law

This Article generates a data set (twelve courts and thirty-two decisions) of foreign judicial citations to the landmark U.S. Supreme Court decision in Brown v. Board of Education. The purpose of this Article is to learn what happens when a case is deterritorialized and reconstituted in a different national scenario, and to conceptualize how courts around the world use foreign authority. My analysis reveals that few foreign courts used Brown in decisions involving education or race and ethnicity. Foreign courts used the case as a form of factual evidence, as a guide in understanding the proper role of a court …
