Description
Preservation Symphony is a short, multi-movement, orchestral composition that explores the versatility of the [016] pitch class set as the dominant unifying force of this cyclical work. The composition is scored for Piccolo, two Flutes, two Oboes, English Horn, two Clarinets, Bass Clarinet, full complement of Brass, Timpani, two Percussionists, and Strings. Movement one is in sonata form; the [016] set is used in structuring its overall formal scheme. The primary focus of the movement is on the tritone [0 6] as a replacement for the traditional tonic and dominant polarity. The movement features a driving force that alternates between pulse subdivisions of even sixteenth notes and sixteenth-note triplets. Movement two is in simple binary form with a central tonality of A. An English Horn solo functions as both the opening of the movement and a transition from the tonality of movement one (F) into the new tonal center of A. The unifying pitch class set [016] is used in this movement in a Phrygian context. Movement two has a contemplative and dark tone, which is in stark contrast to the outer movements. Movement three has a lighter, upbeat nature. The movement is in rondo form with its main theme written in a folk-like character. This movement returns to F as the central tonality, completing the overall tonal plan of the work. As in movement one, it explores the tritone polarity of F and B. The movement also revisits the chromatic mediant relationship found in the middle of movement two in the oboes. The pitch class set is now used in the context of a Lydian-Mixolydian (or acoustic) scale, from which both the central and secondary themes of the rondo are derived.

Description
Delirium is a piece for large wind ensemble that synthesizes compositional techniques to generate unique juxtapositions of contrasting musical elements. The piece is about 8:30 long and uses the full complement of winds, brass, and percussion. Although the composition begins tonally, chromatic alterations gradually shift the melodic content outside of the tonal center. In addition to changes in the melody, octatonic, chromatic, and synthetic scales and quartal and quintal harmonies are progressively introduced throughout the piece to add color and create dissonance. Delirium contains four primary sections that are all related by chromatic mediant. The subdivisions of the first part create abrupt transitions between contrasting material, evocative of the symptoms of delirium. As each sub-section progresses, the A minor tonality of the opening gradually gives way to increased chromaticism and dissonance. The next area transitions to C minor and begins to feature octatonic scales, secundal harmonies, and chromatic flourishes more prominently. The full sound of the ensemble then drops to solo instruments in the third section, now in G# minor, where the elements of the previous section are built upon with the addition of synthetic scales and quartal harmonies. The last division, before the recapitulation of the opening material, provides a drastic change in atmosphere as the chromatic elements from before are removed and the tense sound of the quartal harmonies are replaced with quintal sonorities and a more tonal melody. The tonality of this final section is used to return to the opening material. After an incomplete recapitulation, the descending motive that is used throughout the piece, which can be found in measure 61 in the flutes, is inverted and layered by minor 3rds. This inverted figure builds to the same sonority found in measure138, before ending on an F# chord, a minor third away from the A minor tonal center of the opening and where the piece seems like it should end.

Description
Alkali treated aluminosilicate (geopolymer) was functionalized by surfactant to increase the hydrophobicity for making Pickering emulsion for the first part of this work. In the first part of this study, alkali treated metakaolin was functionalized with cetyltrimethylammonium bromide ((C16H33)N(CH3)3Br, CTAB). The electrostatic interaction between this quaternary ammonium and the surface of the aluminosilicate which has negative charge has taken place. The particles then were used to prepare Pickering emulsion. The resulting stable dispersions, obtained very fast at very simple conditions with low ratio of aluminosilicate to liquid phase. In the second part, the interaction between geopolymer and glycerol was studied to see the covalent grafting of the geopolymer for making geopolymer composite. The composite material would be the basis material to be used as support catalyst, thin coating reagent and flame retardant material and so on, Variety of techniques, Thermogravimetric (TGA), Particle-induced X-ray emission (PIXE), FTIR, Solid state NMR, Powder X-ray diffraction (PXRD), BET surface area, Elemental analysis (CHN), TEM, SEM and Optical microscopy were used to characterize the functionalized geopolymer.

Description
Gloria is a work written for SATB choir and brass quintet that uses the traditional Latin text of the Gloria found in the ordinary of the Mass. The piece is approximately fourteen minutes and explores a variety of textures, colors, and timbres of the brass quintet and choir. The composition uses quartal sonorities mixed with upper tertian structures while avoiding simple triads and stable root position voicings until the most important climactic moments. The Gloria opens with a fanfare presenting the initial rhythmic motive in a call and response between the brass and choir before the irregular meters of the A section enter. The piece develops a variety of sonorities, pitch collections, and timbres before arriving at the first climactic moment on the text "Rex" (King). The music slowly comes to a point of repose with a brass interlude revealing the motives used in the B section. The choir begins the B section a cappella on the text "Dómine Fili unigénite, Jésu Chríste" (Lord Jesus Christ, the only begotten Son). The section features a dialogue between the brass and choir, though the two groups never sound together. The section includes a lyrical soprano duet incorporating dissonant intervals preceding the choir's response on the text requesting the mercy of the Lord. The section comes to a somber, penitential rest ending with the brass quintet response. The piece gradually builds and accelerates to the second climactic moment on the word "Jésu." From there it once again gains momentum toward the return of the A section on the text "Cum Sáncto Spíritu" (With the Holy Spirit). After a climactic "Amen" section, the composition concludes with a return to the material found in the introduction followed by an affirming brass postlude.

Description
Para Mi Alma is a composition for chamber wind ensemble comprised of an Introduction, two dance movements, and a concluding movement featuring the full ensemble in a chorale-like finale. This piece follows the narrative of an abusive relationship, and the emotional rollercoaster that one experiences during the self extrication and consequential rebirth of identity. Para Mi Alma (For My Soul) is scored for chamber wind ensemble with the following instrumentation: piccolo/flute, Bb clarinet, bass clarinet, bassoon; soprano, tenor, and baritone saxophone; trumpet, trumpet/flugelhorn, horn in F, tenor and bass trombone; double bass, and three percussionists - marimba/congas, auxiliary percussion (wind chimes, suspended cymbal, triangle, bass drum, snare drum, double cowbell, tam-tam), and timpani/timbales. The duration of this work is approximately 11’00”.
Each movement portrays a stage in the relationship, and the mental state of the person experiencing abuse. The Introduction begins with a piccolo solo and marimba accompaniment, and gradually builds to the full ensemble; this section of music illustrates the moment that relational ties to the transgressor are cut — a split second of clarity and space before the spiral of anxiety and overwhelming thoughts of self deprecation invade. Movement I is a salsa, representing the dance of two people entering into a relationship. The meter changes and hemiolas serve to upset the underlying groove and create rhythmic tension, while the surface of the music appears unscathed. Finally the dance is interrupted by an aggressive bass solo, which initiates the transition to Movement II. This transition serves to remind the listener of the Introduction, and the dissolution of the relationship; it is characterized by chaos and confused clusters of melodic lines and dissonant harmonies. Movement II is a tango, representative of the emotional extremes of heartbreak, anger, confusion, and shame. The conclusion of the Tango directly segues into Movement III, which features a short brass chorale before building to include the full ensemble. Movement III portrays the support system of family and friends, and personifies the collective effort that takes place in healing and growth.

Description
This fifteen-minute cyclical mass uses excerpts from the text of the Mass Ordinary and is laid out into five movements and across three different languages: Kyrie (Latin), Gloria (Chinese), Credo (English), Sanctus (Chinese), and Agnus Dei (Latin). Rather than following the tradition of celebrating devotion, this mass tells the story of the abuse of power in political and religious leadership. Movements sung in Latin represent the devout Christian base whose motives and inspiration remain pure and divine. The English movement, Credo, has been altered from the original and represents the manipulation and distortion of scripture, truth, and facts by self-serving leaders and politicians. Finally, Chinese movements represent those who are persecuted for their convictions and their identity.
The turmoil of the Chinese movements is characterized by atonality and fast tempos with contrasting, meditative, lyrical B sections. The outer Latin movements contain the familiar Kyrie and Agnus Dei texts in triple canon with the orchestra. The English middle movement is simultaneously familiar and awkward, with harmonies that almost function, under an altered Credo text. After an aria-like passage, the orchestra takes the “I believe” figure and manipulates it in a modal fugato, culminating in a climactic version of the main motive. A repeated double-dotted quarter note—sixteenth-note rhythm followed by a fast tremolo in the castanets make up the central “bangu motive.” This motive is derived from traditional Beijing Opera, in which the bangu is the principal percussion element. As a rhythmic motive, fragments of it appear in every movement and in several different instrument groups. These fragments undergo various transformations before a version of it arrives as the final Agnus Dei rhythmic figure.

Description
The growing use of Learning Management Systems (LMS) in classrooms has enabled a great amount of data to be collected about the study behavior of students. Previously, research has been conducted to interpret the collected LMS usage data in order to find the most effective study habits for students. Professors can then use the interpretations to predict which students will perform well and which student will perform poorly in the rest of the course, allowing the professor to better provide assistance to students in need. However, these research attempts have largely analyzed metrics that are specific to certain graphical interfaces, ways of answering questions, or specific pages on an LMS. As a result, the analysis is only relevant to classrooms that use the specific LMS being analyzed.
For this thesis, behavior metrics obtained by the Organic Practice Environment (OPE) LMS at Arizona State University were compared to student performance in Dr. Ian Gould’s Organic Chemistry I course. Each metric gathered was generic enough to be potentially used by any LMS, allowing the results to be relevant to a larger amount of classrooms. By using a combination of bivariate correlation analysis, group mean comparisons, linear regression model generation, and outlier analysis, the metrics that correlate best to exam performance were identified. The results indicate that the total usage of the LMS, amount of cramming done before exams, correctness of the responses submitted, and duration of the responses submitted all demonstrate a strong correlation with exam scores.

Description
Bruegel is a four movement composition inspired by the paintings and engravings of Flemish artist Pieter Bruegel the Elder (1525-1569). It is scored for Bass Clarinet in Bb, Electric Guitar, One Percussionist (Glockenspiel, Woodblock, Snare, Kick Drum, and Brake Drums), Piano and String Quartet. Each movement explores a painting or engraving from Bruegel’s catalog of works and attempts to embody each piece of art through the use of certain compositional techniques.
The Cripples (Movement I) explores layered rhythms and disjunct melodic fragments which play on the idea of Bruegel’s painting of crippled men trampling over each other and stumbling. Small moments of balance are found throughout only to be lost. Patience (Movement II) is based on an early engraving of Bruegel, which depicts a lone woman who represents a virtue, in this case patience, surrounded by sin and vices. Juxtaposed textures are presented with patience eventually finding itself victorious to temptation. Children’s Games (Movement III) explores a painting which depicts a large number of children playing a plethora of different games. The movement uses graphic notation and plays with the idea of games to create a compositional “game” for the ensemble. Big Fish Eat Little Fish (Movement IV) depicts a large fish eating several smaller fish. A process is introduced which plays on the idea of increasing density and lasts for the bulk of the movement.

Description
Phantom Sun is a ten-minute piece in three sections, and is composed for flute, clarinet in b-flat, violin, cello, and percussion. The three-part structure for this work is a representation of the atmospheric phenomenon after which the composition is named. A phantom sun, also called a parhelion or sundog, is a weather-related phenomenon caused by the horizontal refraction of sunlight in the upper atmosphere. This refraction creates the illusion of three suns above the horizon, and is often accompanied by a bright halo called the circumzenithal arc. The halo is caused by light bending at 22° as it passes through hexagonal ice crystals. Consequently, the numbers six and 22 are important figures, and have been encoded into this piece in various ways.
The first section, marked “With concentrated intensity,” is characterized by the juxtaposition of tonal ambiguity and tonal affirmation, as well as the use of polymetric counterpoint (often 7/8 against 4/4 or 7/8 against 3/4). The middle section, marked “Crystalline,” provides contrast in its use of unmetered sections and independent tempos. The refraction of light is represented in this movement by a 22-note row based on a hexachord (B-flat, F, C, G, A, E) introduced in measure 164 of the first section. The third section, marked “With frenetic energy,” begins without pause on an arresting entrance of the drums playing an additive rhythmic pattern. This pattern (5+7+9+1) amounts to 22 eighth-note pulses and informs much of the motivic and structural considerations for the remainder of the piece.

Description
A potential new class of cancer chemotherapeutic agents has been synthesized by varying the 2 position of a benzimidazole based extended amidine. Compounds 6-amino-2-chloromethyl-4-imino-1-(2-methansulfonoxyethyl)-5-methyl-1H-benzimidazole-7-one (1A) and 6-amino-2-hydroxypropyl-4-imino-1-(2-methansulfonoxyethyl)-5-methyl-1H-benzimidazole-7-one (1B) were assayed at the National Cancer Institute's (NCI) Developmental Therapeutic Program (DTP) and found to be cytotoxic at sub-micromolar concentrations, and have shown between a 100 and a 1000-fold increase in specificity towards lung, colon, CNS, and melanoma cell lines. These ATP mimics have been found to correlate with sequestosome 1 (SQSTM1), a protein implicated in drug resistance and cell survival in various cancer cell lines. Using the DTP COMPARE algorithm, compounds 1A and 1B were shown to correlate to each other at 77%, but failed to correlate with other benzimidazole based extended amidines previously synthesized in this laboratory suggesting they operate through a different biological mechanism.
