In the United States, more than 18 million people suffer from upper extremity injury. This population is in need of a device both to aid in the completion of activities of daily living (eating and grooming), as well as to provide daily muscular therapy. To assist persons suffering from disabling upper extremity neuromuscular diseases, this thesis concerned the redesign of a powered arm brace from a proof-of-concept design to a more functional, marketable product. The principles of Design for Manufacturability and Assembly (DFMA) were employed as part of the design methodology to create a product that could be scaled into production. Additionally, numerical analyses including Finite Element Analysis (FEA) were completed to prove the both the safety and structural integrity of the orthosis in computer simulations. The design was then successfully tested with marked improvement over the previous design, including a 58% reduction in weight, decreased manufacturing costs, and a significant improvement in functionality and comfort.

The Kingston Plains are nine-and-a-half square miles of stump prairie -- a field of stumps from a previously logged forest -- in the central Upper Peninsula of Michigan. Through a mix of personal essay and research, this nonfiction work explores the author's fascination with the area by examining its soil, forest ecology, lumber history, fire ecology, and potential symbolism for a different way of processing the world around us.

One of the most desired assets for a trumpeter is the ability to play in the upper register, also known as the extreme register. Upper-register playing is required in most genres of music, and it is considered one of the most difficult mental and physical challenges of trumpet performance. This paper aims to critically analyze and discuss upper-register playing, thereby serving as a guide enabling trumpet players to more effortlessly master this task. To achieve this, there will be an in-depth analysis of the Baroque approach to the upper register, which will then be compared to the modern approach. The assessment will differentiate among embouchures used, jaw and facial structures (i.e. overbite or under bite, straight teeth, or gaps in teeth), diet, breathing techniques, tongue placement, and equipment or combinations thereof (i.e., different mouthpiece and trumpet combinations). Additionally, a study of past and present professional upper-register masters, as well as myths of upper-register playing, will be presented. This paper is intended to serve as a methodology to upper-register trumpet playing and will offer trumpet performers simple, yet proven, practical methods which can improve proficiency in this critical arena.

The Deadwood Formation is an Upper Cambrian to Lower Ordovician succession of sandstones, shales, siltstones and limestones that blanketed central western North America during the initial Phanerozoic transgression. This transgression led to a broad, shallow epeiric sea which onlapped the Transcontinental Arch to the east and was protected on its westernseawardside by a system of carbonate platforms now exposed in the Rocky Mountains. The Deadwood Formation is mostly a subsurface unit, but several exposures exist in the northern Great Plains due to uplift by Eocene igneous intrusions. Linguliformean brachiopods were recovered from two areas: the Black Hills of South Dakota, and two subsurface cores from Alberta and Saskatchewan. Forty-five species of linguliformean brachiopods assigned to twenty-eight genera were recovered from these localities and described. Giving provisional names, one new family, Holmerellidae, one new subfamily, Neotretinae, five new genera, Amplitreta, Dianabella, Ganotoglossa, Holmerellus, and Vangaporosa, are erected and seventeen new species are described: Amplitreta cyclopis, Amplitreta elongata, aff. Anabolatreta tora, Canthylotreta parislata, Curticia pustulosa, Dianabella artemesia, Ganotoglossa leptotropis, Holmerellus convexus, Holmerellus, acuminatus, Holmerellus limbatus, Kotylotreta nupera, Linnarssonella tubicula, Opisthotreta nuda, Rhondellina albertensis, Tropidoglossa costata, Quadrisonia? sigmoidea, and Vangaporosa dakotaensis. The family Holmerellidae is distinguished by pitted larval shells and smooth postlarval shells, a feature that is unique in the Linguloidea. The composition of the new subfamily Neotretinae recognizes the evolutionary relationship of the genera Neotreta and Rhondellina, which are more closely related to each other than to any other acrotretid genera. Based on a comparison of the brachiopod assemblages with similar faunas from Australia and elsewhere in Laurentia, the sections studied are determined to be late Marjuman (early Late Cambrian) to early Sunwaptan (middle Late Cambrian) in age. The subsurface faunas provide the first biostratigraphic dates for any part of the Deadwood Formation in Canada. Faunas from South Dakota come from strata near the base of the formation and below the first trilobite occurrences, this giving a more refined age for the transgression in South Dakota. A large number of shells with perforations assumed to have been caused by predators were recovered from two localities in South Dakota, and represent the first evidence of predation of fossil lingulids. Two types of perforations were identified: round holes with sharp, non-beveled edges, and irregularly shaped holes with chipped edges. The former hole type is attributed to either steady pressure applied over time (e.g. boring) or to a swift, piercing percussive strike. The latter hole type is attributed to a smashing percussive strike with a blunt appendage. Based on criteria established by the proposed attack-mode models, various hypothetical animals are discussed as potential linguliformean predators. While the evidence for these predators is circumstantial, it indicates a more complex benthic paleoecology that had hitherto been envisaged for the Upper Cambrian.

It is universally accepted that the majority of Ṣa‘īdī (Upper Egyptian) and Cairene consonants correspond with each other very closely. However, the Ṣa‘īdī cognates of Cairene /tˤ/, /g/, and /ʔ/ show significant variation that has not yet been studied phonologically or mapped. The research that has been conducted on these Upper Egyptian cognate sounds is either based on a very small sample size, or lacking phonological distributions for these sounds. This paper revisits the phonological variation and distribution of the Upper Egyptian cognates for the Cairene /tˤ/, /g/, and /ʔ/. This study concludes that its Ṣa‘īdī cognate of the Cairene /tˤ/ is [ɗ] in most regions, and that the Ṣa‘īdī cognates of the /g/, and /ʔ/ differ from previous documentation. / text
