Description
The ability of musicians to perform well in multiple musical styles is increasingly common and necessary. This paper profiles two trombonists who have gone well beyond the ability to function in multiple genres, and are instead considered significant artists. Tony Baker and Alex Iles were chosen to be profiled for this project because both have achieved recognition as solo artists in the genres of classical music and jazz and have performed on international stages as soloists. They also have significant ensemble experience in both classical and jazz settings and are active teachers as well. Both hold-high profile positions that have helped grow their reputations as performers: Mr. Baker as a professor at one of the largest music schools in the United States, the University of North Texas, and Mr. Iles as a highly in-demand freelance musician in Los Angeles. This paper presents interviews with both trombonists that investigate their development as musicians and soloists in both classical music and jazz. They are asked to describe the benefits and challenges of performing at a high level in both styles, and how these have affected their musical voices. Common traits found in their responses are examined, and recommendations are created for musicians seeking stylistic versatility.

Description
Trichloroethene (TCE) is a ubiquitous soil and groundwater contaminant. The most common bioremediation approach for TCE relies on the process of reductive dechlorination by Dehalococcoides mccartyi. D. mccartyi use TCE, dichloroethene, and vinyl chloride as electron acceptors and hydrogen as an electron donor. At contaminated sites, reductive dechlorination is typically promoted by adding a fermentable substrate, which is broken down to short chain fatty acids, simple alcohols, and hydrogen. This study explored microbial chain elongation (MCE), instead of fermentation, to promote TCE reductive dechlorination. In MCE, microbes use simple substrates (e.g., acetate, ethanol) to build medium chain fatty acids and also produce hydrogen during this process. Soil microcosm using TCE and acetate and ethanol as MCE substrates were established under anaerobic conditions. In soil microcosms with synthetic groundwater and natural groundwater, ethene was the main product from TCE reductive dechlorination and butyrate and hydrogen were the main products from MCE. Transfer microcosms using TCE and either acetate and ethanol, ethanol, or acetate were also established. The transfers with TCE and ethanol showed the faster rates of reductive dechlorination and produced more elongated products (i.e., hexanoate). The microbial groups enriched in the soil microcosms likely responsible for chain elongation were most similar to Clostridium genus. These investigations showed the potential for synergistic microbial chain elongation and reductive dechlorination of chlorinated ethenes.

Description
This project uses fourteen transcriptions of Pete Fountain’s solos as examples to
demonstrate traditional jazz clarinet techniques and language in terms of motives,
patterns, and a variety of articulations. This project also includes guidelines on how to
practice jazz improvisation as well as how to apply Fountain’s techniques and jazz
language to one’s own improvisation. Though there are countless musicians who have
made remarkable contributions to the development of the jazz language, Pete Fountain’s
unique style is particularly worthy of study due to his massive media presence, effortless
playing techniques, unique tone quality, and showmanship throughout his career.

Description
Obesity impairs skeletal muscle maintenance and regeneration, a condition that can progressively lead to muscle loss, but the mechanisms behind it are unknown. Muscle is primarily composed of multinucleated cells called myotubes which are derived by the fusion of mononucleated myocytes. A key mediator in this process is the cellular fusion protein syncytin-1. This led to the hypothesis that syncytin-1 could be decreased in the muscle of obese/insulin resistant individuals. In contrast, it was found that obese/insulin resistant subjects had higher syncytin-1 expression in the muscle compared to that of the lean subjects. Across the subjects, syncytin-1 correlated significantly with body mass index, percent body fat, blood glucose and HbA1c levels, insulin sensitivity and muscle protein fractional synthesis rate. The concentrations of specific plasma fatty acids, such as the saturated fatty acid (palmitate) and monounsaturated fatty acid (oleate) are known to be altered in obese/insulin resistant humans, and also to influence the protein synthesis in muscle. Therefore, it was evaluated that the effects of palmitate and oleate on syncytin-1 expression, as well as 4E-BP1 phosphorylation, a key mechanism regulating muscle protein synthesis in insulin stimulated C2C12 myotubes. The results showed that treatment with 20 nM insulin, 300 µM oleate, 300 µM oleate +20 nM insulin and 300 µM palmitate + 300 µM oleate elevated 4E-BP1 phosphorylation. At the same time, 20 nM insulin, 300 µM palmitate, 300 µM oleate + 20 nM insulin and 300 µM palmitate + 300 µM oleate elevated syncytin-1 expression. Insulin stimulated muscle syncytin-1 expression and 4E-BP1 phosphorylation, and this effect was comparable to that observed in the presence of oleate alone. However, the presence of palmitate + oleate diminished the stimulatory effect of insulin on muscle syncytin-1 expression and 4E-BP1 phosphorylation. These findings indicate oleate but not palmitate increased total 4E-BP1 phosphorylation regardless of insulin and the presence of palmitate in insulin mediated C2C12 cells. The presence of palmitate inhibited the upregulation of total 4EB-P1 phosphorylation. Palmitate but not oleate increased syncytin-1 expression in insulin mediated C2C12 myotubes. It is possible that chronic hyperinsulinemia in obesity and/or elevated levels of fatty acids such as palmitate in plasma could have contributed to syncytin-1 overexpression and decreased muscle protein fractional synthesis rate in obese/insulin resistant human muscle.

Description
"Chronos" is a composition by the great jazz pianist, Aaron Parks. Originally arranged for a quartet consisting of piano, upright bass, drums and tenor saxophone, I sought to arrange the piece for a sextet consisting of trombone, alto saxophone, tenor saxophone, guitar, upright, bass, and drums. This thesis outlines my process as I transcribed "Chronos" from the original recording and then arranged it for a new ensemble. It also discusses the difficulties faced in all the phases of the project from transcribing to rehearsing and performing the work. My arrangement is included with the thesis for those who wish to analyze the music as well as a recording of a live performance of my arrangement at The Nash in downtown Phoenix on April 7th, 2015.
