An Argument for the Use of Multiple Segment Stents in Curved Arteries
(2011)Stenting of curved arteries is generally perceived to be more challenging than straight vessels. Conceptually implanting multiple shorter stents rather than a single longer stent into such a curved artery represents a ... -
Sliding bubble dynamics and the effects on surface heat transfer
(2012)An investigation into the eff ects of a single sliding air bubble on heat transfer from a submerged, inclined surface has been undertaken. Existing literature has shown that both vapour and gas bubbles can increase heat ... -
Small Scale Electricity Generation from a Portable Biomass Cookstove: Prototype Design and Preliminary Results
(2013)The World Health Organisation estimates that over 20% of the global population (~1.4 billion people) lack access to electricity. Furthermore, 40% of the global population (~2.7 billion people) rely on the traditional use ... -
Experimental Study of Gas Injected Bubble Growth from Submerged Orifices
(2013)This work investigates the mechanism of adiabatic gasbubblegrowth from submergedorifices with the view of elucidating the interdependence of the bubble shape and the pressure field during growth and departure. Air injection ... -
Microphone Arrays as a Leakage Detection Tool in Industrial Compressed Air Systems
(2012)Compressed air energy is expensive, but common in industrial manufacturing plant. However, a significant part of the generated compressed air energy is lost due to leakage. Best practice requires ongoing leak detection and ... -
The pericellular environment regulates cytoskeletal development and the differentiation of mesenchymal stem cells and determines their response to hydrostatic pressure.
(2013)The objective of this study was to examine the interplay between matrix stiffness and hydrostatic pressure (HP) in regulating chondrogenesis of mesenchymal stem cells (MSCs) and to further elucidate the mechanotransductive ... -
The Composition of Engineered Cartilage at the Time of Implantation Determines the Likelihood of Regenerating Tissue with a Normal Collagen Architecture.
(2013)The biomechanical functionality of articular cartilage is derived from both its biochemical composition and the architecture of the collagen network. Failure to replicate this normal Benninghoff architecture in regenerating ... -
Engineering osteochondral constructs through spatial regulation of endochondral ossification.
(2013)Chondrogenically primed bone marrow derived mesenchymal stem cells (MSCs) have been shown to become hypertrophic and undergo endochondral ossification when implanted in vivo. Modulating this endochondral phenotype may ... -
Site specific inelasticity of arterial tissue.
(2012)Understanding the mechanical behaviour of arterial tissue is vital to the development and analysis of medical devices targeting diseased vessels. During angioplasty and stenting, stress softening and permanent deformation ... -
Mechanically induced structural changes during dynamic compression of engineered cartilaginous constructs can potentially explain increases in bulk mechanical properties.
(2012)Several studies on chondrocyte seeded hydrogels in bioreactor culture report increased mechanical properties of mechanically loaded constructs compared to unloaded free swelling controls despite no significant differences ... -
A Structural Model of Passive Skeletal Muscle shows Two Reinforcement Processes in Resisting Deformation
(2013)Passive skeletal muscle derives its structural response from the combination of the titin filaments in the muscle fibres, the collagen fibres in the connective tissue and incompressibility due to the high fluid content. ... -

Fast numerical simulation of vortex shedding in tube arrays using a discrete vortex method
(2003)Vortex shedding may occur in tube arrays, resulting in strong excitation forces at discrete frequencies. In the past the Strouhal numbers governing vortex shedding in these systems were determined primarily by experiment. ... -
A Decrement Method for Quantifying Nonlinear and Linear Damping in Multidegree of Freedom Systems
(2011)A method is presented which can estimate the linear and nonlinear damping parameters in a lightly damped multidegree of freedom system which allows the system to be decomposed into a set of single degree of freedom nonlinear ... -
Expansion in the presence of FGF-2 enhances the functional development of cartilaginous tissues engineered using infrapatellar fat pad derived MSCs
(2012)MSCs from non-cartilaginous knee joint tissues such as the infrapatellar fat pad (IFP) and synovium possess significant chondrogenic potential and provide a readily available and clinically feasible source of chondroprogenitor ... -
Porous poly(vinyl alcohol)/sepiolite bone scaffolds: preparation, structure and mechanical properties
(Elsevier, 2012)Porous poly(vinyl alcohol) (PVA)/sepiolite nanocomposite scaffolds containing 0-10 wt.% sepiolite were prepared by freeze-drying and thermally crosslinked with poly(arylic acid). The microstructure of the obtained scaffolds ... -
Measurement of grinding temperatures using a foil/workpiece thermocouple
(Elsevier, 2012)The high temperature generated in abrasive processes is the main factor responsible for thermal damage to a ground surface. It can be predicted through the thermal balance of the heat fluxes in the process. Such predictions ... -
Torsion of monofilament and polyfilament sutures under tension decreases suture strength and increases risk of suture fracture
(2012)Background: A continuous running suture is the preferential method for abdominal closure. In this technique the suture is secured with an initial knot and successive tissue bites are taken. At each tissue bite, the needle ...
