A molecular assessment of range expansion of the northern or virile crayfish (Orconectes virilis), crayfish-based community co-structure, and phylogeny of crayfish-affiliated symbionts
DownloadFall 2012
Geographical limits of a species’ range are determined in part by the environmental tolerances of that species, and also by its past and current ability to colonize new areas. Range shifts are a common occurrence in the evolutionary history of almost all taxa; however, anthropogenically-mediated...

Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and texture
DownloadSpring 2014
Structuring of material on the nanoscale is enabling new functional materials and improving existing technologies. Glancing angle deposition (GLAD) is a physical vapor deposition technique that enables thin film fabrication with engineered columnar structures on the (10 to 100) nm scales. In this...

This dissertation examines the phenomenon of suffix ordering in English from a psycholinguistic perspective. Key to this work is an examination of Complexity-Based Ordering, a theory of affix ordering that combines both selectional restrictions and processing constraints. Complexity-Based...

Ankylosaur (Dinosauria, Ankylosauria) foot morphology and an assessment of the function of the limbs and feet
DownloadFall 2011
Morphology and function of ankylosaur dinosaur limbs are explored and analyzed using comparative morphology and finite element analysis. Reconstruction of the forelimb and posture of Pinacosaurus grangeri matches well with trackways attributed to ankylosaurs. A flexed humerus angled away from the...

Characterization of Particulate Matter Morphology and Volatility for Two Direct-Injection Engines
DownloadFall 2015
Particulate matter emitted from two direct injection engines has been characterized by morphology, volatility, mass-mobility exponent, effective density, and size distribution using tandem measurements from a centrifugal particle mass analyzer (CPMA) and differential mobility analyzers (DMA). The...

Comparative Analysis of the Anatomy of the Myxinoidea and the Ancestry of Early Vertebrate Lineages
DownloadFall 2012
The question of whether a hagfish is a true vertebrate or not has profound implications about the ancestry of the clade. New anatomical evidence allows a test of their systematic position. With dissections and serial sections of original specimens, and with a literature review, a comparative...

Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Factors contributing to the competitiveness of Lactobacillus reuteri in sourdough and rodent gut
DownloadFall 2011
Lactobacillus reuteri is a common organism in cereal-based foods and a gut symbiont in humans and animals, yet the molecular mechanisms allowing its persistence in various niches are not well understood. L. reuteri LTH2584 produces reutericyclin and persists in industrial sourdoughs, where acidic...

Pachyrhinosaurus is a peculiar ceratopsian known only from Upper Cretaceous strata of Alberta and the North Slope of Alaska. The genus consists of three described species Pachyrhinosaurus canadensis, Pachyrhinosaurus lakustai, and Pachyrhinosaurus perotorum that are distinguishable by cranial...

Fall 2017
Inflectional morphology presents numerous problems for traditional computational models, not least of which is an increase in the number of rare types in any corpus. Although few annotated corpora exist for morphologically complex languages, it is possible for lay-speakers of the language to...
