BIOFABRICATION STRATEGIES TO GUIDE THE SELF-ORGANISATION OF BIOMIMETIC CARTILAGE AND OSTEOCHONDRAL TISSUES
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)The modest clinical impact of musculoskeletal tissue engineering (TE) can be attributed, at least in part, to a failure to recapitulate the structure, composition and functional properties of the target tissue. This has ... -
Biomechanical origins of osteoporosis
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)The contention of this thesis is that a pathological change in bone tissue material properties during osteoporosis ahers the mechanical stimuli to bone remodelling cells and drives them to adapt the trabecular architecture ... -
Boundary element methods for the prediction of aircraft noise shielding in flight
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Aircraft noise emissions may be significantly reduced by positioning the aeroengines above the wings or fuselage so as to utilize the shielding effect of the airframe. Computational tools are likely to play a key role in ... -
Bubble growth dynamics in nucleate pool boiling with liquid subcooling effects
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)Heat transfer in nucleate pool boiling has been characterized by very high dissipated heat fluxes whilst requiring low driving temperature differences. The rate of bubble growth and the subsequent bubble motion has a ... -
Bubble growth dynamics including gravitational and electric field effects
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)In the present work the hydrodynamics of adiabatic gas bubble growth from a submerged orifice is investigated with the view of elucidating the interdependence of the bubble shape and the pressure field during growth and ... -
Bubble impingement and the mechanisms of heat transfer enhancement
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)Fluid agitation and mixing ensuing from two phase flow has an important role to play within two phase flow heat exchangers, which are at the forefront of energy conversion. Within these environments, vapour bubbles may ... -
Bubble-induced Marangoni convection
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Thermal Marangoni convection about a 1mm radius air bubble situated under a heated wall of constant temperature immersed in a silicone oil layer (Pr = 220) of constant depth 5mm was experimentally investigated using a flow ... -
Cartilage extraceullular matrix-derived scaffolds for joint regeneration
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)The goal of this thesis was to address key limitations associated with autologous chondrocyte implantation (ACI) for articular cartilage regeneration, specifically the need for two hospital stays, cell culture and high ... -
Case study of the Home Energy Saving Scheme : a multidisciplinary approach
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)The EU has set itself the objective of achieving 20% primary energy savings by 2020. Because of the relatively recent move towards sustainability, there is a limited understanding of how effective related policies and ... -
Characterisation and modelling of electro-pneumatic production systems
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Compressed air is a widely employed energy source in modern manufacturing, accounting for a large percentage of plant electrical energy usage. However, the energy efficiency of such systems can be particularly low. Accurate ... -
Characterisation of an integrated telemetric temperature sensor for CFRP milling applications
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The concept of a sensor designed to measure the behaviour of a machining process is a fundamental part of process monitoring and control. The perception of such a sensor is often underestimated when novel applications are ... -
Characterisation of the performance of single point diamond dressers in abrasive processes
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)This thesis presents in-depth investigation and analysis of the dressing of conventional grinding wheels. Grinding is used in the manufacturing industry to achieve a high surface finish which is an important constituent ... -
Characterization of the Erosion of Soft Tissue by Surgical Mesh In Vitro
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)Surgical mesh implants have been extensively used in hernia treatment and pelvic organ procedures, such as organ prolapse and stress urinary incontinence. Since the onset of the use of such implants, major complications ... -
Composite scaffold development and bioreactor culture for bone tissue engineering
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)Bone tissue engineering involves seeding bone cells onto a scaffold, culturing this construct so that mineralisation occurs (by using signalling mechanisms such as growth factors or bioreactors) and then implanting it into ... -
Composition and mechanical properties of osteoarthritic subchondral trabecular tibial bone
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)Osteoarthritis is a disease that has been characterised historically by the focal destruction of cartilaginous tissue and hence, is defined as such. However, recent investigations have brought this pathology into contention. ...
