A Streptozotocin-Induced Model Of Alzheimer's Disease In Mice With Wild-Type Human Tau, Carolyn C. Rudy
A Streptozotocin-Induced Model Of Alzheimer's Disease In Mice With Wild-Type Human Tau, Carolyn C. Rudy
Graduate Theses, Dissertations, and Problem Reports (ETD)
Alzheimer's disease (AD) accounts for 60 to 80% of all dementias, affects over 5 million Americans, and incurs annual healthcare costs of over {dollar}200 billion (Alzheimer's Association, 2012). Hyperphosphorylation of tau, the main component of neurofibrillary tangles observed in AD, leads to deficits in cell structure and function. Because recent data suggest impairments in cerebral glucose utilization and energy metabolism play a prominent role in the pathogenesis of AD, we sought to create a mouse model that emulates the metabolic changes using intracerebroventricular infusions of streptozotocin (ICV-STZ) in transgenic mice expressing human tau. The Barnes maze, a test of spatial …

An Exploration Of Conceptual Teaching In Piano Study: Pedagogical Analysis Of Three Selected Intermediate Piano Works By Two American Composers, William Bolcom And Lowell Liebermann, Justin Douglas Krueger
Graduate Theses, Dissertations, and Problem Reports (ETD)
Music of contemporary classical composers is often neglected because of simple lack of familiarity or because some of the material is difficult; all too frequently, recent music is allotted very little time during the long-term course of a student's piano study. These circumstances may contribute to the current situation, in which, all too often, students may get little encouragement to explore music by contemporary composers.;This paper highlights some possible reasons for the lack of exposure which contemporary classical compositions sometimes receive. The discussion continues by outlining a broad conceptual teaching paradigm and then shows ways in which a conceptual approach …

A Method Of Pricing European Style Equity Options, David Harris
A Method Of Pricing European Style Equity Options, David Harris
Graduate Theses, Dissertations, and Problem Reports (ETD)
The study of option pricing has a very short history, when compared with other elements of economics. Since the publication of a method to price European style equity options by Fischer Black and Myron Scholes in 1973 a vast amount of research on option pricing has occurred. Ultimately, the pricing of equity options depends upon the match of the model and reality. A new method to price option contracts is proposed. It is argued that the distributional assumptions of standard models are uncorrelated with nature. A new model is proposed as a start to a new class of models.
Instrument Comparison For Aerosolized Titanium Dioxide, Anand Ranpara
Instrument Comparison For Aerosolized Titanium Dioxide, Anand Ranpara
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recent toxicological studies have shown that the surface area of ultrafine particles (UFP i.e., particles with diameters less than 0.1 micrometer) has a stronger correlation with adverse health effects than does mass of these particles. Ultrafine titanium dioxide (TiO2) particles are widely used in industry, and their use is associated with adverse health outcomes, such as micro vascular dysfunctions and pulmonary damages.;The primary aim of this experimental study was to compare a variety of laboratory and industrial hygiene (IH) field study instruments all measuring the same aerosolized TiO2.

Examining Childbirth-Related Trauma And Its Effect On Maternal Self-Efficacy And Appraisal Of Infant Temperament, Teresa B. Stire
Graduate Theses, Dissertations, and Problem Reports (ETD)
It is estimated that 3--9% of women will meet full diagnostic criteria for posttraumatic stress disorder (PTSD) following childbirth, with another 20 to 40% being partially symptomatic for the disorder. While precedents and associated factors leading to childbirth related PTSD have been fairly well researched, the postpartum outcomes such as the mother's perception of herself in the parenting role, and her appraisal of her infant's temperament have been far less studied. Other psychiatric disorders have been linked to lower estimations of parental self efficacy and more negative views of infant temperament. This study examined childbirth related trauma and its effect …
Influence Of Geochemical Processes On The Geomechanical Response Of The Overburden Due To Co2 Storage In Saline Aquifers, Sai Bharath Kumar Varre
Influence Of Geochemical Processes On The Geomechanical Response Of The Overburden Due To Co2 Storage In Saline Aquifers, Sai Bharath Kumar Varre
Graduate Theses, Dissertations, and Problem Reports (ETD)
Saline aquifers have been identified as desirable geologic formations, suitable for the storage of carbon dioxide (CO2) in large amounts. While the impermeable caprock layer(s) in the overburden provide(s) the primary trap for injected carbon dioxide, other trapping mechanisms, such as solubility, residual, ionic or mineral trapping, help contribute to CO2 storage. Geochemical reactions alter the petrophysical properties such as porosity in the target reservoir, and may have an influence on the reservoir storage capacity. When CO2 is injected for long periods of time, it changes the fluid pressures and the overburden geomechanical response. The geomechanical response associated with time-dependent …

Evaluating The Inclusion Of Phytase Super-Dose In Various Broiler Diet Formulations And Novel Pellet Binders, John W. Boney
Evaluating The Inclusion Of Phytase Super-Dose In Various Broiler Diet Formulations And Novel Pellet Binders, John W. Boney
Graduate Theses, Dissertations, and Problem Reports (ETD)
Grains commonly used in poultry diets contain phytic acid, a known anti-nutrient that binds dietary phosphorus rendering it unavailable for absorption also decreasing the digestibility of other nutrients. Phytic acid also increases mucin production and endogenous amino acid secretions causing a gut irritant effect which may decrease performance. An abundance of phytase literatures suggests that phytase enzymes can liberate bound phosphorus enhancing phytate phosphorus utilization and bone mineralization. Recently, the use of super-doses of phytase has been suggested to, not only liberate bound phosphorus, but to alleviate the gut irritant effect associated with phytate phosphorus. Therefore, an experiment was conducted …

Compositions Of Criticism: A Reinterpretation Of Gustave Courbet's Paintings Of Nudes, Amanda M. Guggenbiller
Graduate Theses, Dissertations, and Problem Reports (ETD)
This paper investigates the mythological paintings created by Gustave Courbet (1819-1877) in the nineteenth-century, and their connection to Courbet's relationship with the political regime of the French Second Empire. In 1862, Courbet began three variations of one painting, originally titled Study of Women, and shortly after changed to Venus in Jealous Pursuit of Psyche. The mythological context of the paintings was commonly represented in the arts, although the scene Courbet depicted was unusual, and unlike any other. The principles upon which Courbet created his art, which also shaped the concept of Realism, the movement which Courbet started, strongly opposed all …
