Dissociation of hydrogen molecules on the clean and hydrogen-preadsorbed Be(0001) surface
Using first-principles calculations, we systematically study the potential
energy surfaces and dissociation processes for hydrogen molecules on the clean
and hydrogen-preadsorbed Be(0001) surfaces. It is found that the most
energetically favored dissociation channel for H2 molecules on the clean Be
surface is at the surface top site, with the minimum energy barrier of 0.75 eV.
It is further found that after dissociation, hydrogen atoms do not like to
cluster with each other, as well as to penetrate into subsurface sites. For the
hydrogen-preadsorbed Be(0001) surface, the smallest dissociation energy barrier
for H2 molecules is found to be 0.50 eV, which is smaller than the dissociation
energy barrier on a clean Be(0001) surface. The critical dependence of the
dissociation energy barriers for H2 molecules on their horizontal distances
from the preadsorbed hydrogen atom is revealed. Our studies well describe the
adsorption behaviors of hydrogen on the Be(0001) surface.Comment: 17 pages, 9 figure
Summary of Dissertation Recitals Three Programs of Cello Music
Three cello recitals were given in lieu of a written dissertation.
The repertoire was selected for these recitals show the versatility of the cello as a concerto, chamber, and solo instrument. The first recital, Cellist Composers and Arrangers, focused primarily on solo and chamber music composed by cello performers of the last three centuries. The second recital, Solo Cello, contained three significant works for solo cello. The final recital, Haydn C Major, was a performance of Haydn’s C major Concerto with the Utah Chamber Artists in Salt Lake City, UT.

Schumann 1849: Schumann Literature Transcribed and Recorded on the Trombone
The purpose of this dissertation project was to transcribe and record selected works of Robert Schumann on the trombone. Nearing the end of his life and suffering from years of debilitating mental illness, Robert Schumann had an unusually prolific year of composition in 1849. It was during this fruitful period that he wrote Fantasiestücke op. 73, Drei Romanzen op. 94, Adagio und Allegro, op. 70 and Fünf Stücke im Volkston op. 102. For each of these works, Schumann had indicated on the score additional instruments on which the pieces could be played. This CD features the aforementioned works performed on the tenor and alto trombone. This recording features Aaron Zalkind on the trombone and Keith Teepen on piano. Recorded and engineered by Kevin Harbison.

The l=2 stellarator with displaced helical windings
The paper deals with the magnetic surface configuration properties in the frame of a new model of the l=2 stellarator with displaced helical windings. The displacement has been made to provide a better access to the plasma confinement volume. Numerical calculations have shown that the magnetic surface configuration, shifted inward the torus and appearing favorable for plasma confinement, can be realized in the absence of a transverse magnetic field.Проведено вивчення властивостей конфігурації магнітних поверхонь в новій моделі магнітної системи l=2 стеларатора зі зміщеними гвинтовими обмотками. Зміщення запроваджено з метою покращення доступу до об’єму утримання плазми. Показано, що найбільш сприятлива для утримання плазми зміщена в середину тора конфігурація магнітних поверхонь реалізується за відсутністю поперечного магнітного поля.Проведено изучение свойств конфигурации магнитных поверхностей в новой модели магнитной системы l=2 стелларатора со смещенными винтовыми обмотками.
