Epidermal appendages are found on every vertebrate this world has to offer. In fish, these are commonly represented by scales. While we have a solid grasp of how scales develop, little is known about the underlying genetic mechanisms behind these phenotypic changes. Using two species of African cichlids (Labeotropheus fuelleborni and Tropheops “red cheek”) with varying scale phenotypes, we sought to examine their F2 hybrid offspring and statistically link the responsible genetic elements to their respective parental phenotypes through Quantitative Loci Trait (QTL) analysis. Scales were removed from six different locations across the midline of each individual. Then, numerous traits on each scale were measured, and these values were used in the QTL analysis. 42 significant QTL were identified, with multiple QTL intervals possessing promising candidate genes. These genes include: fgfr1b, efna5a, TGIF1, eIF6, and col1a1a. Previous studies have implicated these particular genes and gene families to play important roles in scale and placode development. However, they represent the minority of QTL intervals discovered, providing direction for future research towards the other QTL intervals represented by this study.

We study the Born-Oppenheimer approximation for a symmetric linear triatomic molecule in two space dimensions. We compute energy levels up to errors of order ε⁵, uniformly for three bounded vibrational quantum numbers n₁, n₂, and n₃; and nuclear angular momentum quantum numbers â ≤ kε^-3/4 for k > 0. Here the small parameter ε is the fourth root of the ratio of the electron mass to an average nuclear mass. / Master of Science

<p> A set of scales was created, the "Modified Conibear Scales" which can be used as a basis of comparison to rate the performance of other traps in the areas of impact energy, closing time and clamping force. Further, a detailed set of secondary non quantitative characteristics was presented.</p> <p> Using the above information, several promising traps were rated in order to assess these scales, give some immediate results and indicate promising traps or trap features. Further work in the field was facilitated by providing a detailed experimental procedure, complete lists of data and a calibrated trap for animal research.</p> / Thesis / Master of Engineering (MEngr)

With overcrowded schools as a project vehicle, this thesis investigates the expansion and contraction of an existing infrastructure" and the relationship that developed between the two. The proposed intervention, guided by the site, touches on an urban scale by generating a gateway into the city. / Master of Architecture

The extended Lydian Locrian theory of harmony (ELL) is a system of analyzing harmonies and progressions according to their position along a vast spectrum of colors. The musical premise is that chords and progressions spanning upwards around the circle of fifths sound brighter, whereas chords and progressions spanning downwards around the circle of fifths sound darker. This simple premise gives rise to a complex but unified system of harmonic structures and relations, a system which provides a valuable tool for analyzing and composing music, especially of advanced tonal genres. ELL not only provides fruitful techniques for analyzing certain kinds of traditional harmonies and progressions but also provides a framework for discovering more exotic and colorful harmonies and progressions.

The following research questions were investigated: (a) Can the age-mates scales from the Dales developmental task scales be used with southwestern-urban adolescent populations? (b) Are there any systematic differences between northeastern-nonurban and southwestern-urban subject populations on the response to these scales? The subjects consisted of 884 adolescents, 11 through 15 years, evenly divided by sex. Subject responses were analyzed by sex and age groups using Guttman scalogram analysis. Goodman's test of significance revealed that the results could have occurred by chance (p > .05). The instrument in its present form was not found useful'-for an urban population. Lack of reproducibility made comparison of the performance of urban and nonurban adolescents unjustified.
