Apparent behaviour of charged and neutral materials with ellipsoidal fibre distributions and cross-validation of finite element implementations
(2012)Continuous fibre distribution models can be applied to a variety of biological tissues with both charged and neutral extracellular matrices. In particular, ellipsoidal models have been used to describe the complex material ... -
Biomechanics of the stick insect antenna: Damping properties and structural correlates of the cuticle
(2011)The antenna of the Indian stick insect Carausius morosus is a highly specialized near-range sensory probe used to actively sample tactile cues about location, distance or shape of external objects in real time. The length ... -
Combining BMP-6, TGF-β3 and hydrostatic pressure stimulation enhances the functional development of cartilage tissues engineered using human infrapatellar fat pad derived stem cells
(2013)The objective of this study was to identify a combination of growth factors that could be used with hydrostatic pressure (HP) stimulation to enhance the functional development of cartilaginous grafts engineered using human ... -
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 ... -
The effect of cyclic hydrostatic pressure on the functional development of cartilaginous tissues engineered using bone marrow derived mesenchymal stem cells
(2011)Mechanical signals can play a key role in regulating the chondrogenic differentiation of Mesenchymal Stem Cells (MSCs). The objective of this study was to determine if the long-term application of cyclic hydrostatic pressure ... -
The effect of the VOF-CSF static contact angle boundary condition on the dynamics of sliding and bouncing elliposidal bubbles.
(2011)The staticcontactangle is the only empiricism introduced in a Volume of Fluid?Continuum Surface Force (VOF?CSF) model of bubbly flow. Although it has previously been shown to have a relatively limited effect on the accuracy ... -
The effect of wheel eccentricity and run-out on grinding forces, waviness, wheel wear and chatter
(2011)The effect of grinding-wheel eccentricity on grinding forces, wheel wear and final waviness height was studied. Eccentricity was evident in force oscillations and acceleration and audio measurements. A model was developed ... -
Examination of the Local and Fluctuating Heat Transfer due to Swirling Jets Impinging upon a Heated Horizontal Surface
(2011)In the area of heat dissipation, impinging jets have been researched over many years and are a well defined method of attaining high heat transfer coefficients. Many different techniques have been looked at over past years ... -
Field Trial Testing of an Electricity-Producing Portable Biomass Cooking Stove in Rural Malawi
(2014)A novel off - grid electricity - producing device has been designed for integration with biomass - fuelled improved cooking stoves commonly in use in the developing world. The device operates on the ... -
Fracture toughness of locust cuticle

A general correlation for the stagnation point Nusselt number of an axisymmetric impinging synthetic jet
(2011)Whereas the heat transfer mechanisms in steady impinging jets are well understood, the available knowledge of heat transfer to impinging synthetic jets remains inconsistent. This paper provides an objective comparison of ... -
Heat transfer in adjacent interacting impinging synthetic jets
(ASME, 2009)An impinging synthetic jet can attain heat transfer rates comparable to a continuous jet, without net mass input. However it needs a forced cross-flow to supply fresh cooling medium. The vectoring effect of adjacent synthetic ... -
High dynamic velocity range particle image velocimetry using multiple pulse separation imaging
(2011)The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable particle displacement. Various techniques have extended the dynamic range, however flows with a wide velocity ... -
In vivo dynamics of the internal fibrous structure in smooth adhesive pads of insects
(2012)Many insects with smooth adhesive pads can rapidly enlarge their contact area by centripetal pulls on the legs, allowing them to cope with sudden mechanical perturbations such as gusts of wind or raindrops. The short time ... -
Investigation into the Machining of Biomedical Grade Polymers, Considering Cryogenic Pre-Cooling

Mechanical behaviour of transparent nano fibrillar cellulose-chitosan nano composite films in dry and wet conditions
(2014)Transparent, biocompatible and biodegradable chitosan (CS) nanocomposite films rein- forced with nanofibrillar cellulose (NFC) were prepared by solution casting. The effects of NFC content on the mechanical properties in ... -
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 ... -
Mechano-regulation of mesenchymal stem cell differentiation and collagen organisation during skeletal tissue repair
(2009)A number of mechano-regulation theories have been proposed that relate the differentiation pathway of mesenchymal stem cells (MSCs) to their local biomechanical environment. During spontaneous repair processes in skeletal ... -
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 ...
