From Eve To Eve: Women's Dreaming In The Middle Ages And Renaissance, Rebecca Dark Jan 2010

From Eve To Eve: Women's Dreaming In The Middle Ages And Renaissance, Rebecca Dark

English Dissertations - Archive

This project examines reports of the dreams of women in fictionalized as well as historical, biographical, and hagiographical accounts from the English Middle Ages and Renaissance. Because an unstable body/spirit dualism forms the basis for both dream theory and anti-feminism during these periods, in texts where women's dreams are reported the instabilities of the two discourses are magnified, resulting in discursive discontinuities that reveal the presence of multiple cultural languages. My argument, based in part on the Bakhtinian concept of heteroglossia, is that these texts are characterized by the generally accepted misogynistic ideas of the period but also demonstrate the …

Nanoparticle Bridge Dna Biosensor, Hong-Wen Huang Jan 2010

Nanoparticle Bridge Dna Biosensor, Hong-Wen Huang

Material Science and Engineering Dissertations - Archive

A new DNA sensing method is demonstrated in which DNA hybridization events lead to the formation of nanoparticle satellites that bridge two electrodes and are detected electrically. The hybridization events are exclusively carried out only on specific locations, the surfaces of C-ssDNA modified 50 nm GNPs. The uniqueness of this work is that only a small number of T-ccDNA molecules (<10) is required to form the nanoparticle satellites, allowing ultra-sensitive DNA sensing. The principle of this new DNA sensing technique has been demonstrated using target DNA and three-base-pair-mismatched DNA in 20nM concentrations. Three single-stranded DNA (ssDNA) system is used in our experiment which includes Capture-ssDNA (C-ssDNA), Target-ssDNA (T-ssDNA) and Probe-ssDNA (P-ssDNA). Both C-ssDNA and P-ssDNA are modified by a thiol group and can hybridize with different portions of T-ssDNA. T-ssDNA requires no modification in three ssDNA system, which is beneficial in many applications. C-ssDNA modified 50nm gold nanoparticle (C-50au) and P-ssDNA modified 30nm gold nanoparticle (P-30au) are prepared through the reaction of thiol-gold chemical bonding between thiolated ssDNA and gold nanoparticle (GNP) (C-ssDNA with 50nm GNP, P-ssDNA with 30nm GNP). We controllably place the C-50au only on the SiO2 band surface (~ 90nm width) between two gold electrodes (source and drain electrodes) by forming positively- and negatively-charged self-assembled monolayers (SAMs) on SiO2 and gold surface, respectively. DNA modified GNP is negatively charged due to ionization of phosphate group on DNA back bone. C-50au therefore is negatively charged and can only be attracted toward SiO2 area (repelled by negatively charged gold electrode surface). The amine group of positively-charged SAMs on SiO2 surface is then passivated by converting to non-polar methyl functional group after C-50au placement. P-30au is first hybridized with T-ssDNA in the solution phase (T-P-30au formed) and is introduced into DNA detection device in which C-50au are immobilized on ~90nm width SiO2 band (between two gold electrodes). The passivation step ensures every T-P-30au are attached only to C-50au through hybridization (T-P-30au will not be attracted toward SiO2 surface or gold electrodes). GNP bridges are formed across the electrodes and provide an electrical path between two gold electrodes.We ensure that every T-P-30au only hybridizes on the surface of C-50au by (1) accurately controlling C-50au placement between two gold electrodes, (2) passivating positively-charged SAMs on SiO2 surface after C-50au immobilization. When T-P-30au hybridize with C-50au on ~90nm wide SiO2 surface, GNP bridges form and provide an electrical path between two gold electrodes even with only a few hybridization events. Experimental results show that even a few GNP bridges formed on SiO2 band can provide a significant conductance change from an open circuit to a conductive circuit (current = 0.5 uA at voltage = 0.1 V with four GNP bridge). We also used 3-base-pair-mismatched ssDNA (3mm-ssDNA) as a control experiment, which always resulted in an open circuit (no GNP bridge formed). Our detection device is compatible with current CMOS fabrication technology and can be manufactured on a wafer scale. The direct electrical output of this DNA detection technique provides a promising basis for high-throughput screening (can be fabricated on a wafer scale) with no expensive equipment required.

Effect Of Friction On The Zel'dovich Von Neumann Doring To Chapman Jouguet Transition, Sushma Rao

Mechanical and Aerospace Engineering Theses - Archive

Detonation theory proposes Chapman-Jouguet state of equilibrium due to the sonic speed of the products relative to the wave. Experimental observations however indicated the existence of a sub-Chapman-Jouguet state. The dissertation proposes that friction plays a role in defining such a sub-optimal state in detonation wave propagation in ducts. The problem is addressed analytically by decoupling the friction losses from the chemical reactions. The non-equilibrium conditions associated with detonation is modeled by detailed chemistry.
