Abstract:

Experimental proof is presented that some of the motions responsible for transverse relaxation (T₂) in deuterium magnetic resonance (²H NMR) experiments on acyl chains of a model membrane in the liquid crystalline phase are extremely slow on the ²H NMR time scale being characterized by a correlation time T₂ > ѡq⁻¹. The experiments used to investigate these slow motions involve a form of the Carr-Purcell-Meiboom-Gill pulse sequence modified so as to be suitable for ²H NMR (q-CPMG). The most plausible mechanism responsible for T₂ relaxation is the gradual change in the average molecular orientat

Using transverse relaxation based MRI, this thesis has developed new quantitative approaches to characterise the progression of Osteoarthritis in animal models and has introduced this type of characterisation for the assessment of mammographic density. For the first time, it has identified the collagen architecture in the kangaroo knee cartilages using MRI. The three case studies presented in this thesis have experimentally investigated and evaluated the analytical efficacy of the transverse relaxation based techniques and quantitative T2 measurements. It has also identified previously unknown

Abstract:

[Truncated abstract] Clinical magnetic resonance imaging (MRI) scanners were used to investigate the measurement and imaging of ferrimagnetic particle concentrations in biological tissues in vivo. The presence of ferrimagnetic particles tends to increase the proton transverse relaxation rate (R2) of water protons in tissue. A quantitative image of R2 can be generated using a series of single spin echo magnetic resonance images acquired using clinical MRI scanners and analysing the images using techniques based on that reported by Clark and St. Pierre (2000).

Abstract:

We report here the observation of non-ohmic behavior in the dominant oscillatory component (the cigar component) of ρ('H) in ultrapure magnesium when the magnetic field, 'H, is parallel to [0001] and the current density, 'J, lies in the basal plane. In order to study this new phenomenon systematically, we had to overcome two experimental problems. The first was the design of an experimental probe which could reproducibly control, at low temperatures, the contact resistance at one of the points where current is injected into the sample without disturbing the sample's orientation with respect to

Abstract:

Numerical simulations are invaluable in the development and understanding of magnetic resonance imaging (MRI) techniques. Motivated by the goal of understanding the behaviour of the functional MRI (fMRI) signal in brain tissue, this thesis employs a deterministic simulation technique in which the transverse magnetization and B0 inhomogeneity within a voxel are spatially discretized and the stochastic self-diffusion of water molecules is modelled as a Gaussian isotropic blurring of the transverse magnetization. While this simulation technique has existed since fMRI was in its infancy, its use h

Abstract:

La résonance magnétique nucléaire (RMN) fournit des informations structurelles et dynamiques précieuses à l'échelle atomique, cependant, la faible sensibilité et résolution des signaux empêchent l’étude d'objets moléculaires plus importants. Nous présentons 3 stratégies de marquage isotopique pour différentes expériences RMN des protéines en solution et démontrons leur potentiel pour l'étude structurale des biomolécules. Parmi les stratégies envisagées, 2 utilisent l'expression in vitro pour obtenir des protéines marquées sélectivement sur un groupe chimique et/ou acide aminé dans un environne

Abstract:

O retalho miocutâneo transverso do abdome (TRAM) é um dos principais métodos utilizados na reconstrução mamária, sendo que este tipo de cirurgia apresenta grande incidência de necrose. O objetivo deste estudo foi verificar a eficácia do campo magnético estático (CME) e do ultrassom pulsado de baixa intensidade (UPBI) na viabilidade do retalho TRAM em ratos. Para tanto, quarenta e oito ratos machos foram distribuídos em quatro grupos homogêneos: G1 (Controle) - sem exposição ao campo magnético e ultrassom, G2- expostos ao campo magnético sul, G3 - expostos ao campo magnético Norte e G4 - estimu

Abstract:

Techniques based on principle of nuclear magnetic resonance (NMR) belong to the most modern methods for studying physical, chemical and biological properties of materials [1]. Their universality predestinates them for application in a wide range of scientific disciplines, e.g. in medicine to study properties of tissues. Advantages of techniques utilizing principle of NMR consist in their noninvasiveness and thoughtfulness to human health or studied material. In addition, no undesirable effects of magnetic force field have been so far proved by research. Objectives of this Diploma Thesis are ev

Abstract:

INTRODUÇÃO: O plexo braquial é uma rede de estruturas nervosas responsáveis pela inervação motora e sensitiva do membro superior. Os métodos por imagem são de importância fundamental para a complementação diagnóstica tanto na localização como na caracterização do tipo de lesão que acomete o plexo braquial. O objetivo deste trabalho foi avaliar a eficácia do exame de ultrassonografia (US) na visualização do plexo e avaliar o método comparativamente à ressonância magnética (RM). MATERIAL E MÉTODOS: Este é um trabalho prospectivo comparativo entre US e RM na avaliação da anatomia do plexo braquia

Abstract:

The electromagnetic scattering problem of normal incident waves on an elliptic chiral cylinder is considered. The cylinder is assumed to be homogeneous and isotropic and extends infinitely long in the z direction. An exact boundary value solution for the scattering problem of the TM wave by the elliptic chiral cylinder is analyzed and presented. The solution is based on the separation of variable technique in the elliptic cylinder coordinates system, and expressed in terms of Mathieu and modified Mathieu functions. The incident, transmitted and scattered electromagnetic waves are expressed in

碩士<br>中原大學<br>機械工程研究所<br>94<br>The vibration of a cracked plate under in-plane force, transverse magnetic field and simply supported at all edges are considered. Based on the von plate theory, the equation of motion has been including in-plane force, transverse magnetic and damping coefficient. The linear natural frequency is affected by different crack length and aspect ratio which are compared with the results in literature and they are closed. The equations of vibration are reduced to an ordinary differential equation by assuming mode shape and Galerkin’s procedure. The natural frequency is
