The Eleven Nocturnes For Solo Piano Of Lowell Liebermann: A Field-Chopin-Faure Lineage, Martin Harvey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since 1987, Lowell Liebermann (b. 1961) has composed eleven piano Nocturnes, making him the most significant recent contributor to the genre. This research analyzes these Nocturnes, six of which have no previously published analysis. This paper also considers Liebermann's Nocturnes as a continuation of the tradition of nocturne-writing, initiated in the nineteenth century by composers like John Field and continued by Fryderyck Chopin and Gabriel Faure. Numerous composers have written Nocturnes since Faure's opus 119 in 1921; however no one did so with an interest as marked as Liebermann's. Moreover, Liebermann shares with Faure many stylistic features. Liebermann is therefore …

New Tools For Real-Time Study Of Embryonic Development, Lauren M. Browning

Theses and Dissertations in Biomedical Sciences

Embryonic development represents one of the most complex and dynamic cellular processes in biology, and plays vital roles in understanding of functions of embryonic stem cells (ESCs) and design of ESC-based therapy. Conventional assays and fluorescence-based imaging methods have been widely used for the study of embryonic development. These conventional methods cannot effectively provide spatial and temporal resolutions with sufficient sensitivity and selectivity that are required to depict embryonic development in vivo in real-time at single-cell and single-molecule resolutions. In this dissertation, we have developed a wide range of innovative tools for real-time study of embryonic development. These new tools …

Measurement Of Polarized Proton-Proton Elastic Scattering At The Relativistic Heavy Ion Collider (Rhic), Ivan Koralt

Physics Theses & Dissertations

Elastic proton-proton (pp) scattering is one of the most fundamental processes in nature and yet, it is one of the most difficult to describe. There are two interactions involved in this process: electromagnetic (Coulomb) and hadronic (strong) interactions. Underlying exchange mechanisms of these two interactions are the virtual photon and the Pomeron exchange, respectively. The difficulty of elastic pp scattering arises from the fact that the nature of the Pomeron and its exchange are not well understood and need a theoretical approach, which is still under development.

Melanoma inhibitory activity (MIA) is a secretory protein that is highly correlated with the malignancy and metastasis of malignant melanomas. We used MIA as our target to evaluate the effect of nsEPs on metastasis. Pulsed (experimental) and unpulsed (control) cells were incubated at 37°C under a 5% CO₂ atmosphere. …

The Effects Of Intent And Consequences On The Assignment Of Penalties Related To Hiv Non-Disclosure Situations, Yang Deng

Psychology Theses & Dissertations

Laws related to HIV require individuals infected with HIV to disclose their HIV-positive status before engaging in sexual behavior. These laws vary as to whether to include the intent of HIV non-disclosure as a criterion for prosecution. Penalty assignment for HIV non-disclosure is consistent with moral judgment. Literature regarding moral judgment has been inconsistent as to whether individuals process information regarding intent and consequences independently or interdependently when recommending penalties. The present study seeks to explore the effects of intent and consequences on recommended penalties in HIV non-disclosure situations. A 3(intent) × 2(consequence) ANOVA design was conducted with recommended penalties …

Analysis And Simulation Of Kinetic Model For Active Suspensions, Panon Phuworawong

Mathematics & Statistics Theses & Dissertations

In this research, we study the recently proposed kinetic model for active suspensions, where the active particles are assumed to be rigid rod and are driven in the suspension either by their own biological/chemical forces or external electric/magnetic fields. We first study the stability of the isotropic suspension in quiescent flow. Then we investigate the weak shear perturbation of the isotropic state and study some rheological properties of the suspension by explicit analytic formulas derived directly from the model. For imposed shear, we give some bifurcation diagrams of the stable states in some parametric spaces through numerical simulations. Some rheological …

The Response Of Commercial Banks To Credit Stimuli, Denise Williams Streeter
