Description
Capsaicin and dihydrocapsaicin account for 90% of capsaicinoids when it comes to the pungency of peppers. Capsaicin stability was investigated through a cooking and storage parameter where three different tests were done; cooking duration, cooking temperature, and storage stability. The concentration of capsaicinoids was quantified through gas chromatography-mass spectrometry where those values were then used to determine the total Scoville heat units (SHU). Furthermore, half-life was determined by finding the decay rate during cooking and storage. Results showed that there was an increase in degradation of capsaicinoids concentration when peppers were cooked for a long period of time. Degradation rate increases with increasing temperatures as would be expected by the Arrhenius equation. Hence, if a maximum pungency is wanted, it is best to cook the least time as possible or add the peppers towards the end of the culinary technique. This would help by cooking the peppers for a short period of time while not being exposed to the high temperature long enough before significant degradation occurs. Lastly, the storage stability results interpreted that a maximum potency of the peppers can be retained in a freezer or refrigerator opposed to an open room temperature environment or exposure from the sun. Furthermore, the stability of peppers has a long shelf life with even that the worse storage condition's half-life value was 113.5 months (9.5 years). Thus, peppers do not need to be bought frequently because its potency will last for several years.

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.

Description
Witching Hours is the debut studio album of Chicago-born, Phoenix-residing trumpet player John Michael Sherman. It is a consummation of his work in the Arizona State University jazz studies program both as a performer and composer. Featured on the album are several other musicians who John Michael played alongside throughout his tenure at ASU, including Chaz Martineau on tenor saxophone, Evan Rees on piano, Reid Riddiough on guitar, Vince Thiefain on bass, Matt McClintock on drums, and Dan Meadows on baritone saxophone. The album features seven pieces, all original compositions or arrangements. The first track, "Workin' My Nerves", is a blues shuffle in the key of F. This is followed by "Scarborough Fair", an arrangement of the classic English folk tune in a rock style. The title track, "Witching Hours", is an cadaverous linear composition in 7/4 which is followed by "Goliath", a pseudo-tone poem about the biblical giant. "I Should Have Known" is a pensive ballad featuring an a capella intro and cadenza, followed by the most recent composition, a minor blues-esque piece entitled "Who Said That?" The final track, "Don't Change A Thing", is an upbeat samba which was written in John Michael's first year of college. These pieces demonstrate an understanding of the jazz tradition and exhibit influences from such musicians as Clifford Brown, Freddie Hubbard, Wayne Shorter, and Snarky Puppy. The album was recorded at Tempest Recording in Tempe and produced by Clarke Rigsby. Clarke is a veteran recording engineer and is the first choice of many of Phoenix's finest jazz musicians, including thesis director and head of the ASU jazz department Michael Kocour. The pieces were composed and recorded under the guidance of Mike Kocour and Jeff Libman. Witching Hours represents a culmination of John Michael's course in the Arizona State University jazz department and his endeavors as a trumpet player and composer.
