Midi Electronic Wind Instrument: A Study Of The Instrument And Selected Works, Matthew J. Swallow Jan 2016

Midi Electronic Wind Instrument: A Study Of The Instrument And Selected Works, Matthew J. Swallow

Graduate Theses, Dissertations, and Problem Reports (ETD)

The development of the MIDI (Musical Instrument Digital Interface) electronic wind instrument (EWI) stemmed from earlier electronic instruments including analog/digital synthesizers, earlier control devices (Lyricon), and electronic instruments using a "blow tube trigger generator" (Yamaha WX) or breath controllers (Yamaha BC). Developing such devices began as early as the 1940s and were originally intended for compositional use instead of performance. However, the technology of electro-acoustic sounds continued to expand commercially from the 1950s through the 1970s, including more general access to sound synthesis and live performance. Various companies including Yamaha, Akai, Moog, Korg, and others would establish lines of synthesizers …

Brook Trout (Salvelinus Fontinalis) Preference Of Aquatic Versus Terrestrial Prey In Appalachian Headwater Streams, Erin E. Thayer Jan 2016

Brook Trout (Salvelinus Fontinalis) Preference Of Aquatic Versus Terrestrial Prey In Appalachian Headwater Streams, Erin E. Thayer

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis aims to investigate the foraging behavior of Brook Trout (Salvelinus fontinalis), specially focusing on prey preference. Brook Trout are mainly restricted to head-water streams in Appalachia, which is a portion of their native range. These environments generally have low autochthonous materials. Therefore, resident aquatic organisms rely heavily on terrestrial inputs, i.e. leaf litter and terrestrial invertebrates (TI's), to subsidize individual energy requirements at critical times of the year. There is mixed evidence demonstrating stream dwelling trout show either a feeding preference towards aquatic invertebrates (AI's) or towards TI's. Chapter one is an in depth literature review of headwater …

Using The Instructional Beliefs Model To Examine Instructional Feedback In The Classroom, Melissa F. Tindage Jan 2016

Using The Instructional Beliefs Model To Examine Instructional Feedback In The Classroom, Melissa F. Tindage

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to examine the role that instructional feedback plays in student engagement using Weber, Martin, and Myers's (2001) Instructional Beliefs Model (IBM). The proposed IBM for this dissertation included first-order constructs (i.e., instructional feedback, course workload, course difficulty, and students' feedback orientation), a second-order construct (i.e., feedback self-efficacy), and a third-order construct (i.e., student engagement). As hypothesized, instructional feedback (i.e., developmental, fairness) is positively associated with feedback self-efficacy, while course workload and course difficulty are negatively associated with feedback self- efficacy. However, only two dimensions of students' feedback orientation (i.e., utility, retention) were positively associated …

Development Of A Computational Platform For Methane-Induced Vented Explosions, Francis R. Kronz Iii Jan 2016

Development Of A Computational Platform For Methane-Induced Vented Explosions, Francis R. Kronz Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Accidental expositions in enclosures, such as industrial and residential buildings, lead to a pressure rise that may injure or kill the personnel as well as damage the construction. For example, an overpressure as small as ∼0.1 atm is enough to kill a person or break glass items, while ∼1 atm overpressures may crucially destroy the structure, including collapsing the walls. A standard remedy strategy against such a disaster is employing venting areas such as windows to allow the expanding gas to escape and thereby reducing the maximal overpressure. There are two common ways how to predict the pressure rise in …

Assessment Of Molecular Action Of Direct Gating And Allosteric Modulatory Effects Of Meprobamate (Miltownrtm) On Gaba A Receptors, Manish Kumar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Meprobamate (tradenames Miltown, Equanil) is a schedule IV anxiolytic and the primary metabolite of the muscle relaxant carisoprodol. Meprobamate modulates GABAA (gamma-aminobutyric acid type A) receptors, and has been described as having barbiturate-like activity. A thorough understanding of its mechanism remains ill-defined, however. To gain insight into its actions, we have conducted a series of studies using recombinant GABAA receptors. In alphaxbetazgamma2 GABAA receptors (where x = 1-6 and z = 1-3), the ability to enhance GABA-mediated current was evident for all alpha subunit isoforms, with the largest effect observed in alpha5-expressing receptors. Direct gating was comparable with all alpha …

Effects Of Pristine And Nitrogen-Doped Multi-Walled Carbon Nanotubes On Human Lung Epithelial And Fibroblast Cells, Amy Mihalchik

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multi-Walled Carbon Nanotubes (MWCNT) were first described by Iijima in 1991 as "needle-like tubes" made up of concentric sheets of graphene lattice composed of hexagonal carbon units. MWCNT have been reported to be extremely strong, light-weight, and durable, thus making them a highly valued nanomaterial commercially. In order to improve their electrical conductivity and dispersibility for industrial and biomedical uses, materials scientists began functionalizing CNT in the mid-1990s. One type of functionalized MWCNT, nitrogen doped-MWCNT (ND-MWCNT), have nitrogen directly incorporated into the carbon lattice, disrupting sp2 bonding and decreasing the crystallinity of MWCNT. Nitrogen-doping significantly increases the brittleness, chemical reactivity, …
