The Life And Keyboard Works Of (Franz) Xaver Scharwenka (1850-1924), Michael Patrick Mihalyo Jan 2002

The Life And Keyboard Works Of (Franz) Xaver Scharwenka (1850-1924), Michael Patrick Mihalyo

Graduate Theses, Dissertations, and Problem Reports (ETD)

(Franz) Xaver Scharwenka (1850-1924) was a highly acclaimed performer, teacher, editor, and composer of international fame during the late Romantic period. Overshadowed by the innovative styles of a number of contemporaneous composers including Ravel, Debussy, and Scriabin, Scharwenka's works gradually disappeared from the teaching studio and the concert hall. Regrettably, his compositions, although critically acclaimed in his lifetime, are now for the most part out of print and rarely performed. This study explores Scharwenka's works as a significant addition to the repertory of the late Romantic literature for study and performance. This research project, the result of a lengthy investigation …

Exchange Bias And Its Angular Dependence In Iron Zinc Fluoride/Cobalt Bilayers., Hongtao Shi

Graduate Theses, Dissertations, and Problem Reports (ETD)

When materials with antiferromagnetic (AF)/ferromagnetic (F) interfaces are cooled through the Neel temperature (TN) of the AF in a magnetic field, a unidirectional magnetic exchange anisotropy (EA) is induced in the F layers. Such anisotropy is manifested by a shift of the center of the F hysteresis loop by an amount known as exchange bias HE. Exchange anisotropy has attracted much attention in the last decade due to its applications in magnetic random access memory, permanent magnets, and magnetic recording media. Despite this interest, the basic mechanism responsible for EA is not well understood. In this thesis the EA is …

Study Of The Rheological Properties Of Nomex Fibrids, Long Han Dec 2001

Study Of The Rheological Properties Of Nomex Fibrids, Long Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

Paints and caulks typically contain (spherical) fumed silica particulates as viscosity enhancers. A similar viscosity enhancement can be achieved by using aramid fibrids. Aramid fibrids are believed to form microstructures in suspensions because of the "space-filling" nature of their shapes and thus provide a convenient means of introducing desired rheological behavior for various commercial applications.;The flow responses of aramid fibrids dispersed in mixtures of corn syrup and water were determined in dynamic shear, steady shear, low shear capillary, and extensional stretching flows. Yield stress, strong shear thinning, thixotropy, and strong dispersion effects were observed, and these are consistent with observed …

Parent-Infant Interactions During Acute Painful Procedures, Catherine Bradford Mcclellan Dec 2001

Parent-Infant Interactions During Acute Painful Procedures, Catherine Bradford Mcclellan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the current recognition of infant procedural pain and distress, there is a dearth of research, both in the assessment and treatment literature, of infant procedural distress. This study examined how specific parent behaviors relate to infant procedural distress and whether this relation is mediated by birth order. Results indicated that females were rated as more distressed than were males, and that birth order did not prove to be a distinguishing factor in infant distress. Finally, while some behaviors appear to have a similar influence on both preschoolers' and infants' behaviors, parents' behavior during infants' distressing procedures were found to …

Order Effects Of Fear And Pain Induction, Kevin Erik Vowles Dec 2001

Order Effects Of Fear And Pain Induction, Kevin Erik Vowles

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although pain responding and emotional states such as fear are highly correlated and appear to interact, the causal relations between these variables have yet to be fully defined. This study sought to further illuminate these relations by investigating how exposure to one of these states (i.e., pain or fear) affects responding to the other. The order in which participants experienced fearful or painful stimuli was manipulated, as well as fear level (i.e., "low" & "high"). Measures of behavioral escape, heart rate, and verbal reports were obtained throughout four experimental trials, as well as rankings of aversiveness for all stimuli encountered. …
