Abstract:

ers of and perhaps confirmation of the reality of status and servitude. The focus of Resonance was a visual art exhibition centered on the interpretation and modification of the Korean Buddhist bronze temple bell. As an artist of part Korean descent, heavily influenced by popular American culture and traditional Italian glassblowing techniques, it was my goal to create glass forms based on historical objects. The glass forms reflect my personal, technical and material interests. They are also an interpretation of the bell within contemporary and historical culture. The exhibition examined the wayan object both physically and spiritually contained resonance and how that resonance affected all that heard it. The Korean temple bell from the Unified Silla period (676 AD-918 AD) is an example of superb craftsmanship and devotion to king and religion. It also represents the expenses incurred in production, which put innumerable hardships on the lower class. The peasants were obliged to pay heavy taxes, donate their personal bronze objects, and provide labor resulting in an "increasing impoverishment [in] the lives of the common people. Increasing numbers of them could not repay their debts and were reduced to slavery." (Eckert, 49) If a King wanted to produce a great work of art to honor the Buddha, it was the peasantry who sacrificed and provided for its creation. During one such project, the immense Emille bell was cast in the year 771 AD. The largest bell in Korea, when struck could be heard for forty miles on a clear night. One has to wonder what emotions were felt when the immense bronze bell was seen or heard. Twelve hundred years ago, the king might have felt great pride, a Buddhist monk perhaps intense piety, but how did the lower class feel? A peasant working, relaxing, or sleeping forty miles away was supposed to envision the voice of Buddha. But more than likely, they were reminded of their need to pay taxes and tribute. The Korean temple bell was used as a tool to communicate from one group to another without personal interaction. The enlightened used it to communicate with the commoners, the wealthy to the indentured, and it reinforced the repressive nature of a monarchy that closely aligned itself with religion. It was used as a reminder to enforce the hierarchical status quo.

Abstract:

The primary purpose of this study was to clarify the underlying principles of singers' resonance and to examine some of the pedagogical practices associated with the traditional schools of singing and contemporary voice science. The secondary purpose was to determine which principles should be retained, discarded, or altered.An examination of the voice pedagogy literature revealed recurrent references to resonance. This implied that the concept is of some importance to voice pedagogy. Singers' resonance has, however, been presented in diverse contexts indicating that (1) it has a number of denotations and connotations, (2) it is sometimes used ambiguously, or inaccurately, and (3) a further investigation of the topic might yield clarity to the field of voice pedagogy.It was determined that though there are many important voice pedagogy methodologies, classically trained professional concert and opera singers of international reputation are taught to optimize singers' resonance both in order to be heard and to produce the accepted tone. It was found that those precepts which are based upon acoustic laws should be conserved and those which are not should be abandoned, altered, or when appropriate, acknowledged as metaphorical.

Abstract:

Noise is often viewed as something unfortunate and unavoidable, however with the development of Stochastic Resonance (SR) theory it has been shown to have beneficial effects in many non-linear systems. We have explored the SR phenomenon via numerical simulations of two such systems. The first one is a one-dimensional Brownian particle in a bi-stable potential and the second a simple model of a signal neuron both subject to a periodic input signal. We have investigated the system responses for different input signal frequencies and noise levels in order to determine both an optimal noise level and any dependencies upon the input signal frequency.

Abstract:

Using a phenomenological schematic model of multipole giant resonances we consider the effects of overlapping of their doorway components. The conccpt of the partial widths of a giant resonance becomes ambiguous when the escape widths get comparable with the spacings between the components. In such a case, the partial widths determined in terms of the K- and S-matrices differ from each othcr. The mixing of the doorway components due to the interaction via the common decay channels influences significantly their multipole strengths, widths and positions in energy.

Abstract:

The procedure of cardiographic magnetic resonance imaging requires patients to hold their breath for up to twenty seconds, creating an uncomfortable situation for many patients. It is proposed that an acquisition scheme using spiral trajectories is preferable due to their much shorter total scan time; however, spiral trajectories suffer from a blurring effect caused by off-resonance frequencies in the image area. There are several methods for reconstructing images with reduced blur and Conjugate Phase Reconstruction has been chosen as a method for implementation into Matlab-script for evaluation in regards to image reconstruction quality and computation time. This method finds a conjugate to the off-resonance from a field map to demodulate the image and an algorithm for frequency‑segmented Conjugate Phase Reconstruction is implemented along with an improvement called Multi-frequency Interpolation. The implementation is tested through simulation of spiral magnetic resonance imaging using a Shepp‑Logan phantom. Different off-resonance frequencies and field maps are used to provide a broad view of the functionality of the code. The two algorithms are then compared to each other in terms of computation speed and image quality. It is concluded that this implementation might reconstruct images well but that further testing on actual scan sequences is required to determine the usefulness. The Multi-frequency Interpolation algorithm yields images that are not useful in a clinical context. Further study of other methods not requiring a field map is suggested for comparison.

Abstract:

Pendant ma thèse de doctorat, j’ai eu la grande chance de travailler sur le développement de nouvelles méthodes de deux techniques spectroscopiques complétement différentes : la Résonance Magnétique Nucléaire (RMN) et la Spectroscopie de Masse par Résonance Cyclotronique Ionique à Transformée de Fourier (FT-ICR/MS). En tant que méthodologiste, mon but principal a été d’améliorer les méthodes existantes et la théorie. En RMN, l’outil fantastique de la manipulation des spins permet la mise en place des séquences d’impulsions, et en FT-ICR, les rapports masse sur charge (m/z) des ions et des fragments d’ions obtenus par différents chemins de fragmentation peuvent être appliqués à des problèmes en chimie, biochimie et médecine. Le manuscrit de ma thèse de doctorat comporte deux parties. Les sujets abordés étant différents, ce manuscrit a été rédigé pour que chaque chapitre puisse être lu indépendamment. La première partie aborde la RMN dans le chapitre I. Dans ce chapitre, nous avons amélioré une méthode développée précédemment dans l’equipe pour l’étude de l’échange rapide des protons par RMN. Nous avons adapté la méthode à l’étude de l’acide aminé histidine, système en apparence simple mais qui s’est avéré très compliqué à l’étude. La deuxième partie de ma thèse de doctorat aborde la spectroscopie de masse et comprend deux chapitres. Dans le chapitre II, nous avons essayé de faire revivre et de mettre en œuvre une méthode longtemps oubliée ; il s’agit de la méthode d’isolement d’ions par éjection sélective (‘notch ejection’) par spectroscopie de masse FT-ICR. Un autre sujet abordé pendant ma thèse, qui est décrit dans le chapitre III, concerne l’utilisation de trois impulsions rf dans une expérience à deux dimensions (2D) ICR. Notre objectif a été de mieux comprendre la complexité du comportement des ions pendant cette expérience 2D ICR, en particulier pour le cas d’impulsions courtes
This thesis encompasses methodological developments in both nuclear magnetic resonance and Fourier transform ion cyclotron resonance mass spectrometry. The NMR section explores the effects of scalar relaxation on a coupled nucleus to measure fast exchange rates. In order to quantify these rates accurately, a precise knowledge of the chemical shifts of the labile protons and of the scalar couplings is normally required. We applied the method to histidine where no such information was available a priori, neither about the proton chemical shifts nor about the one-bond scalar coupling constants J(1H15N), since the protons were invisible due to fast exchange. We have measured the exchange rates of the protons of the imidazole ring and of amino protons in histidine by indirect detection via 15N. Not only the exchange rate constants, but also the elusive chemical shifts of the protons and the coupling constants could be determined. For the mass spectrometry section, the ion isolation project was initiated to study the effect of phase change of radiofrequency pulses. Excitation of ions in the ICR cell is a linear process, so that the pulse voltage required for ejecting ions must be inversely proportional to the pulse duration. A continuous sweep pulse propels the ion to a higher radius, whereas a phase reversal causes the ion to come to the centre. This represents the principle of ‘notch ejection’, wherein the ion for which the phase is reversed is retained in the ICR cell, while the remaining ions are ejected. The manuscript also contains a theoretical chapter, wherein the ion trajectories are plotted by solving the Lorentzian equation for the three-pulse scheme used for two-dimensional ICR. Through our simulations we mapped the ion trajectories for different pulse durations and for different phase relations

Abstract:

The trapping effect is investigated close to the elastic threshold. The nucleus is described as an Open quantum mechanical many-body system embedded in the continuum of decay channels. An ensemble of compound nucleus states with both discrete and resonance states is investigated in an energy-dependent formalism. It is shown that the discrete states can trap the resonance ones and also that the discrete states can directly influence the scattering cross section.

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Nuclear Engineering, 1999.
Includes bibliographical references (leaves 96-100).
This thesis describes the design and applications of an improved Nuclear Magnetic Resonance (NMR) microscope, which permits MRI to study small sample sizes ( < 2mm) at high resolution (up to 2[mu]m). The effects of molecular diffusion and local variations in the magnetic susceptibility in NMR microscopy are described, which, along with the intrinsic low sensitivity of NMR, are the fundamental limitations to resolution. Molecular diffusion in the presence of a magnetization grating not only broadens the point spread function but also reduces the signal intensity. The significance of these effects depends strongly on the magnetic field gradient strengths and imaging protocols. A NMR microscope for a standard bore 14.lT magnet was developed, it is equipped with a highly efficient. solenoidal RF coil and three orthogonal gradients with strengths of 1260G / cm for Gz , 760G/cm for Gy , and 410G/cm for Gx at 15A. A modified CTI sequence is presented which incorporates strong pulsed gradients, Ernst angle excitation, CP coherent detection and reduced k-space sampling. It is the optimal pulse sequence for acquiring high-resolution ( < 5[mu]m) NMR images (best signal-to-noise ratio per unit time) when the effect of molecular diffusion is significant. It is demonstrated that this new sequence makes it possible to acquire images with a high resolution of 2[mu]m x 2[mu]m x 8[mu]m within a few hours. A wide variety of images have been acquired using the new microscope, and representative images are presented to demonstrate the potential of NMR microscopy as a new tool in developmental biology research. In particular, used in combination with other biological techniques, NMR microscopy can provide a robust, non-invasive, 3D imaging approach to quantifying changes in structure due for instance to radiative exposure, therapy, and natural growth or genetic modifications.

Abstract:

An atomic resonance filter (ARF), composed of a cell containing an absorbing gas and two interference/absorption filter stacks, is designed to be both wide angle and ultra-narrowband. The bandwidth of this filter, in the range of 1-10mA, is determined by the absorption linewidth of the absorbing gas. Light entering the ARF within this bandwidth excites the gas to a highly excited state, and the fluorescence cascade back to the ground state emerges from the gas cell as the detected signal. The interference/absorption filter stacks insure that light not interacting with the gas does not pass through the ARF. The ARF is necessarily wide-angle due to the isotropic absorption properties of the gas. This dissertation models the processes involved in atomic absorption to determine the performance of an ARF that uses cesium as the absorbing gas. This model uses the Voigt absorption profile to obtain a correlation between the frequency of the traveling photon and the velocity of the absorbing atom. Results of computer simulations based on this model are presented along with experimental measurements. The ARF characteristics of importance include its efficiency and the temporal response of the filter. These characteristics are determined as a function of temperature and the input photon frequency. The effect of an additional buffer gas, which is included to decrease the ARF response time is investigated.

Abstract:

The central theme of this thesis is the use of imaging Surface Plasmon Resonance (iSPR) as a tool in the characterization of surfaces with laterally varying properties. Within the scope of this work, an instrument for iSPR analysis was designed and built. SPR is a very sensitive technique for monitoring changes in optical properties in the immediate vicinity of a sensor surface, which is very useful in biosensing and surface science research. We have employed SPR in the Kretschmann configuration, wherein surface plasmons are excited by means of an evanescent field arising from total internal reflection from the backside of the sensor surface. In iSPR, the signal is the reflectivity of TM-polarized light which is measured using an imaging detector, typically a CCD camera. Advantages of this technique include extreme surface sensitivity and, because detection is done from the backside, compatibility with complex samples. In addition, SPR is a non-labeling technique, and in imaging mode, a lateral resolution in the µm range can be attained. The imaging SPR instrument could be operated in either wavelength interrogation mode or in intensity mode. In the former case, the objective is to find the SPR wave-length, λSPR, which is the wavelength at which the reflected intensity is at a minimum. In intensity mode, a snapshot of the intensity reflectance is taken at a fixed wavelength hand incidence angle. In biosensor science, the use of an imaging technique offers a major advantage by enabling parallelization and thereby increasing throughput. We have, for example, used iSPR in biochemical interaction analysis to monitor immobilization and specific binding to protein and synthetic polypeptide micro arrays. The primary interest has been the study of soft matter surfaces that possess properties interesting in the field of biomimetics or for applications in biosensing. Specifically, the surfaces studied in this thesis include patterned self-assembled monolayers of thiolates on gold, a graft polymerized poly(ethylene glycol) (PEG) based hydrogel, a dextran hydrogel, and a polyelectrolyte charge gradient. Our results show that the PEG-based hydrogel is very well suited for use as a platform in protein immobilization in an array format, owing to the very low unspecific binding. In addition, well defined microarray templates were designed by patterning of hydrophobic barriers on dextran and monolayer surfaces. A polypeptide affinity microarray was further designed and immobilized on such a patterned monolayer substrate, in order to demonstrate the potential of analyte quantification with high sensitivity over a large dynamic range. Furthermore, iSPR was combined with electrochemistry to enable laterally resolved studies of electrochemical surface reactions. Using this combination, the electrochemical properties of surfaces patterned with self assembled monolayers can be studied in parallel, with a spatial resolution in the µm regime. We have also employed electrochemistry and iSPR for the investigation of potential and current density gradients on bipolar electrodes.

In this study, a Surface Plasmon Resonance (SPR) optical sensor, based on Kretschmann configuration, was designed and constructed. SPR is a useful tool for obtaining quantitative kinetic and affinity information on biomolecular interactions. The resolution and the sensitivity of our homemade SPR system was determined and optimized by using thiols and sucrose solutions. The data were normalized and processed to increase the resolution of the system. The sensograms were obtained and the kinetic constants were analyzed. The sensogram of the thiols solutions illustrated the process of association of the thiols on gold surface. The sensogram of the sucrose solutions shown, that the sucrose doesn't have association on gold surface.

Abstract:

This thesis is an exploration of creating an essence in architecture through a sense of ambition and harmony. The ambition for a design to have an architectural presence and establish a clear identity, while achieving a harmony of numerous aspects of the project in order to simplify the inherent complexities of architecture and allow the ambitious identity to be clearly present. The investigation begins with the analysis of ruins as the result of a natural process that strips down a building of secondary components and leaves the exposed soul of the architecture. As a specific example, the thesis explores the Roman ruins, how they exude their cultural history and often how they express the initial architectural intent and identity. The ambition of Rome is carried to the harmony of Florence and finally to the embodiment of harmonious ambition in Michelangelo. His work constantly achieved an ambition in creating a new identity with each masterpiece while always attaining a beautiful moment of harmony. The thesis explores not just the wonders of Michelangelo's life, but his inspirations and mastery of ancient traditions as well as his influence on the world after him. At the conclusion of the exploration, I propose a place of learning that both honors Michelangelo and his resonance throughout history and creates a new harmonious ambition.

Gabriel, Tina Louise. "Empathic resonance : an autoethnography." Thesis, Bournemouth University, 2018. http://eprints.bournemouth.ac.uk/30458/.

Full text

Abstract:

This thesis developed from infrequent experiences of intense connection with clients during psychotherapy; eventually realised as Empathic Resonance. These profound experiences cultivated the intrigue to understand their occurrences and the implications for clinical practice. The literature did not directly address how empathic resonance occurred, nor its place as evidence of highly skilled and advanced counselling/psychotherapy work. The main aim of the thesis was to address the question of how these experiences happened and develop a model of practice. Clear objectives were advanced to meet the thesis aims. A comprehensive literature review was conducted, representing an original conceptual framework. This required testing via comparison with fieldwork experiences. The data collected had to be anonymised and required a container to contextualise the experiences, therefore, an appropriate methodology was selected. The montage form of autoethnography enabled the fragmented clinical experiences to be set into whole fictionalised clinical stories, representing standalone accounts. A thematic analysis of the stories developed the conceptual framework into a model of practice. The model is an integrative representation of the literature review and fieldwork, it answers the main aim of the thesis, which sought to understand how these experiences occurred. The findings of the thesis clarify the phenomenon of empathic resonance, specifically, how the concepts work together from within a dialogical relationship and facilitate empathic resonance. Empathy and resonance are relational attunement concepts which lead to deepening alignment, communicating to the client knowing awareness of the client’s feeling state. Empathic resonance (alignment) essentially rediscovers dissociated aspects of the self, which become available for emotional processing, linking empathic resonance with the transpersonal literature. The implications of the thesis support a strong argument for the use empathy and resonance when working with trauma, specifically dissociated traumas which can be glimpsed via mindfulness when empathically resonating. The phenomenon aids emotional processing, the alleviation of distressing trauma symptomology, resilience, and emotional regulation as part of the reparative/developmentally needed relationship.

Abstract:

The work presented in this thesis has involved the development and experimental implementation of a new method incorporating Nuclear Magnetic Resonance (NMR) methodology, and which enables a volume to be accurately defined and non-invasively interrogated within a larger object, by a sequence of radiofrequency (RF) and linear magnetic field gradient pulses. The most important feature of the VOISINER (volume of interest by selective inversion, excitation and refocusing) sequence is its flexibility with respect to the location and size of the region of interest. The spatial coordinates and the size of the volume of interest can be directly selected from conventional NMR images and then converted into the VOISINER sequence by an appropriate setting of the radiofrequency carrier frequencies of the frequency-selective RF pulses and an appropriate scaling of the field gradient strengths used during those RF pulses. As part of the experimental protocol, the VOISINER sequence was actually combined with conventional spin echo imaging in order to facilitate the selection of the region of interest and the optimization of the spatial sensitivity profile of the localization process. The applicability of the VOISINER sequence was then examined under various experimental conditions in order to evaluate the factors that can deteriorate or improve the efficiency of its spatial selectivity and detection sensitivity. Potential extensions of the VOISINER technique for extracting a variety of high-resolution NMR information have been explored and experimentally demonstrated by combining it with conventional NMR methodology. In particular, it was combined with the inversion recovery method to measure on a model system, spatially localized spin-lattice (T₁) relaxation times. With regard to imaging, studies of a model system have been used to evaluate the technical prospects for using the VOISINER sequence as the basis for high-resolution imaging of small regions within a large object. Finally, to demonstrate that the technique is applicable for studies of living systems, it was tested on a human forearm and spatially localized ¹H high-resolution spectra were successfully obtained from muscle tissue and bone marrow.

Abstract:

Magnetic resonance imaging (MRI) can be used to image diffusion in liquids, such as water in brain structures. Molecular diffusion can be isotropic or anisotropic, depending on the fluid's environment, and can therefore be characterized by a scalar, D, or by a tensor, D, in the respective cases. For anisotropic environments, the eigenvector of D corresponding to the largest eigenvalue indicates the preferred direction of diffusion.
This thesis describes the design and implementation of diffusion tensor imaging on a clinical MRI system. An acquisition sequence was designed and post-processing software developed to create diffusion trace images, scalar anisotropy maps, and anisotropy vector maps. A number of practical imaging problems were addressed and solved, including optimization of sequence parameters, accounting for flow effects, and dealing with eddy currents, patient motion, and ghosting. Experimental validation of the sequence was performed by calculating the trace of the diffusion tensor measured in various isotropic liquids. The results agreed very well with the quantitative values found in the literature, and the scalar anisotropy index was also found to be correct in isotropic phantoms. Anisotropy maps, showing the preferred direction of diffusion, were generated in human brain in vivo. These showed the expected white matter tracts in the corpus callosum.

Abstract:

The interaction between non-spherical nuclear charge distribution and the electric field gradient is described. Expressions for the energy levels (I = 1), the nuclear quadrupolar resonance, NQR, transition frequencies and line shape are derived. The general equations to obtain the inverse line width parameter, T$ sb2 sp star,$ from the self-quenched super-regenerative oscillator, SRO, NQR spectra are derived and tested.
The construction and operation of the $ sp{14}$N Sullivan and Dean SRO spectrometers are described. Limits in the sensitivity of the SRO to yield T$ sb2 sp star$ data are discussed. The operation and the constraints in obtaining line width data from a pulsed-FT spectrometer are given. The temperature dependence of $ sp{14}$N NQR frequencies, T$ sb2 sp star$ and line widths of series of anilines and hexamethylenetetramine are reported.
The NQR frequency and the contribution of static and dynamic effects to the line width are discussed as a function of temperature. The observed phase transitions are discussed.
