Application of a biomechanical finite element spine model to the vicious cycle scoliosis growth theory: evaluation of improved FEA geometry and material assignment
DownloadFall 2009
Scoliosis is defined as the abnormal three dimensional curvature of the spine with 80% of all cases being idiopathic in nature. If left unchecked, this condition can cause cardio-pulmonary complications and occasionally death. Currently, the most common method of treatment of scoliosis is through...

Various X-ray imaging modalities, such as planar X-ray films, dual energy X-ray absorptiometry and computed tomography have been utilized to estimate bone strength for osteoporotic subjects. However, emerging cases of spontaneous femoral shaft fracture in osteoporotic patients after years of...

Development and Analysis of Magnetic Carbon Nanotube and Microbubble-Assisted High Centrifugation Field Techniques For The Increase of Cell Membrane Permeability
DownloadSpring 2014
To cure diseases at the gene level, therapeutic biomaterials need to enter the cells. However, since the cell membrane is a highly selective structure, its permeability is usually very low. In this thesis, we propose two innovative and efficient methods to increase cell membrane permeability....

Direct shear tests were used to establish the shear behaviour of continuous planar-joints, discontinuous stepped-joints and discontinuous open-joints. The joints were cast in a Synthetic rock made of plaster, sand and water and tested under normal stresses that ranged from 50 kPa to 3.5 MPa. A...

FINITE ELEMENT CHARACTERIZATION OF THE BEHAVIOUR OF MASONRY INFILL SHEAR WALLS WITH AND WITHOUT OPENINGS
DownloadFall 2014
The current design practice is to ignore the interaction between masonry infill walls and containing frames due to the inadequate and incomplete guidance in current codes and standards. Most investigations on the behaviour of masonry infill shear walls were performed on scaled specimens and...

Graphene Reinforced Adhesives for Improved Joint Characteristics in Large Diameter Composite Piping
DownloadSpring 2013
Higher specific properties and corrosion resistance of fibre reinforced polymer (FRP) pipes make them a potential candidate for replacing metallic piping structures. This research project is concerned with adhesively bonded FRP pipe sections. The project can broadly be classified into three...

Investigation of the Tearing Mechanism of Bonded Soft Elastomers with Finite Interfacial Friction
DownloadFall 2015
The role of interfacial slippage on the deformation and stress fields near an interfacial crack are investigated in detail. First, the limiting extents of interfacial bonded friction, defined as the frictionless' andno-slip' cases, were modeled as hyperelastic elastostatic boundary value problems...
