A 12 month prospective cohort study of injury in international rowers.
(2010)Objective: In this study, the injury incidence and association with type and volume of training in international rowers were described. Design: A prospective cohort design was used over a 12- month period. Patients: ... -
3D Bioprinted Cartilaginous Templates as Developmentally Inspired Implants for Large Bone Defect Regeneration
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2022)Whilst bone possesses an inherent capacity for regeneration, defects above a critical size cannot heal on their own. Damaged or diseased bone can be treated using autografts or a range of different bone grafting biomaterials, ... -
3D bioprinting of cartilage-mimetic implants for biological joint resurfacing
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2020)A major challenge in the field of tissue engineering and regenerative medicine is the development of effective therapies for treating large cartilage or osteochondral defects and ultimately regenerating whole osteoarthritic ... -
3D Bioprinting of Developmentally Inspired Templates for Bone and Joint Regeneration
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)There is an urgent need to develop alternatives to synthetic joint prosthesis to promote the regeneration of diseased osteoarthritic joints. Cell based therapies have shown promise for repairing cartilage and bone; however, ... -
3D bioprinting of prevascularised implants for the repair of critically-sized bone defects
(2021)For 3D bioprinted tissues to be scaled-up to clinically relevant sizes, effective prevascularisation strategies are required to provide the necessary nutrients for normal metabolism and to remove associated waste by-products. ... -
3D bioprinting spatiotemporally defined patterns of growth factors to tightly control tissue regeneration
(2020)Therapeutic growth factor delivery typically requires supraphysiological dosages, which can cause undesirable off-target effects. The aim of this study was to 3D bioprint implants containing spatiotemporally defined patterns ... -
3D Bioprinting Strategies To Engineer Structurally Organised Meniscal Tissue Grafts
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)Lesions to the meniscus are common sports-related injuries that can lead to articular cartilage degeneration and osteoarthritis if left untreated. While surgical repair procedures and meniscal substitutes offer better ... -
A 3D printed acoustic metamaterial liner to reduce low-frequency aeroengine noise
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)As the level of air travel continues to increase, so too does the demand for better noise-reduction technologies for aircraft. The environmental noise produced by aircraft has been shown to have a significant adverse effect ... -
3D printed microchannel networks to direct vascularisation during endochondral bone repair
(2018)Bone tissue engineering strategies that recapitulate the developmental process of endochondral ossification offer a promising route to bone repair. Clinical translation of such endochondral tissue engineering strategies ... -
3D printing of fibre-reinforced cartilaginous templates for the regeneration of osteochondral defects
(2020)Successful osteochondral defect repair requires regenerating the subchondral bone whilst simultaneously promoting the development of an overlying layer of articular cartilage that is resistant to vascularization and ... -
A biomechanical analysis of the trunk and spine during paediatric cerebral palsy gait
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)Movement pathologies in the lower limbs of children with cerebral palsy are well established in the literature. However, movement pathologies of the upper body, in particular the trunk, are less well defined. Mechanical ... -
A Bridgman Furnace Front Tracking Model
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)The Bridgman furnace is widely used in industry and research, mainly because it provides a means to directionally solidify materials in a controlled manner, so that the resulting microstructure, and hence material properties, ... -
A forward advancing wave expansion method for numerical solution of large-scale sound propagation problems
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)The study of atmospheric somid propagation has become an important subject since noise polhition problems emerged as a highly relevant matter in several areas such as sociology, economics, regulations and standards. Modelling ... -
A new technique for vortex methods in computational fluid dynamics
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2002)The random vortex method is a Lagrangian technique which involves solving the stream function-vorticity formulation of the Navier-Stokes equations. Discrete vortex particles, which are created at the surface to satisfy ... -
A practical framework for strategic noise mapping
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008)Environmental noise is a major form of pollution and it is estimated that at least one quarter of the population of the EU suffer a reduced quality of life due to exposure to noise. To address the problem the European Union ... -
A stochastic model of damage accumulation in acrylic bone cement : application to failure modelling of cemented hip replacement
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)Acrylic bone cement, used to fixate several forms of orthopaedic joint replacement prosthesis, has a variable fatigue resistance arising mainly from porosity. It is argued that deterministic modelling assumptions of ...
