Urban high-density construction sites and their surrounding community: Issues encountered and strategies adopted by contractors

Spillane, John P.; Flood, Michael; Oyedele, Lukumon O.; von Meding, Jason K.; Konanahalli, Ashwini (ARCOM: Association of Researchers in Cosntruction Management, 2013)

Inner city developments are a common feature within many urban environments. Where these construction sites are not managed effectively, they can negatively impact their surrounding community. The aim of this paper is ...
The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters

Cusack, Patricia B.; Callery, Oisín; Courtney, Ronan; Ujaczki, Éva; O'Donoghue, Lisa M.T.; Healy, Mark G. (Elsevier, 2019)

Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ...
The use of silicone materials to model abdominal aortic aneurysm behaviour

Doyle, Barry J.; Callanan, Anthony; Corbett, Timothy J.; Cloonan, Aidan J.; O'Donnell, Michael R.; Vorp, David A.; McGloughlin, Timothy M. (2008)

This paper aims to identify the rupture locations of abdominal aortic aneurysms. Dow Corning Sylgard 184 was mechanically characterised. Five idealised models were then manufactured using this silicone rubber which were ...
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P,N and suspended solids from agricultural wastes applied to grassed soils

Murnane, John G.; Brennan, R.B.; Healy, Mark G.; Fenton, O. (American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2015)

Diffuse pollutant losses containing phosphorus (P), nitrogen (N), and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N, and SS losses in runoff from grassed ...
Using additive manufacturing to produce injection moulds suitable for short series production

Whelan, Conor; Sheahan, Con (Elsevier, 2019)

Additive Manufacturing (AM) is claimed to be a serious competitor to traditional manufacturing methods in the production industry despite very few firms taking full advantage of its capabilities in bringing products to ...
Using finite element analysis to develop a digital twin of a manufacturing bending operation

Hinchy, Eoin; Carcagno, C.; O'Dowd, Noel P.; McCarthy, Conor T. (Elsevier, 2020)

In today’s business environment, the trend towards more product variety and customization is unbroken. Due to this development, the need of agile and reconfigurable production systems emerged to cope with various products ...
Using open-source microcontrollers to enable digital twin communication for smart manufacturing

Hinchy, Eoin; O'Dowd, Noel P.; McCarthy, Conor T. (Elsevier, 2019)

One of the key enabling technologies for the smart factory is the Digital Twin, which can be described as a digital model of a physical entity. In smart manufacturing, a digital twin, also referred to as a cyber-physical ...
Using serious games to inform mass customization production methods from the fuzzy front-end of new product development

O'Sullivan, Michael; Sheahan, Con (Elsevier, 2019)

Mass customization means to offer products or services which meet the demands of each individual customer, but which still can be produced and delivered with mass production efficiency. The buzz surrounding technologies ...
Validity of synthetic bone as a substitute for osteoporotic cadaveric femoral heads in mechanical testing: a biomechanical study

O'Neill, F.; Condon, F.; McGloughlin, Timothy M.; Lenehan, Brian; Coffey, Calvin J.; Walsh, Michael T. (British Editorial Society of Bone and Joint Surgery, 2012)

IntroductionThe objective of this study was to determine if a synthetic bone substitute would provide results similar to bone from osteoporotic femoral heads during in vitro testing with orthopaedic implants. If the synthetic ...
The variation of median nerve functionality with wrist postures typical of computer use and a novel ultrasound technique for the diagnosis of carpal tunnel syndrome

Donoghue, Maurice F (University of Limerick, 2011)

Carpal tunnel syndrome (CTS) is an affliction that affects numerous people in an occupational and recreational environment. One area commonly linked to the development of this condition is computer use. This is due to ...
Vessel asymmetry as an additional diagnostic tool in the assessment of abdominal aortic aneurysms

Doyle, Barry J.; Callanan, Anthony; Burke, Paul E.; Grace, Pierce A.; Walsh, Michael T.; Vorp, David A.; McGloughlin, Timothy M. (Elsevier, 2008)

Abdominal aortic aneurysm (AAA) rupture is believed to occur when the local mechanical stress exceeds the local mechanical strength of the wall tissue. On the basis of this hypothesis, the knowledge of the stress acting ...
Wear of ultra-high molecular weight polyethylene (UHMWPE) in total knee prostheses: a review of key influences

McGloughlin, Timothy M.; Kavanagh, A.G. (Institute of Mechanical Engineers, 2000)

The formation and development of wear is now widely accepted as one of the major concerns in the long-term survivorship of contemporary knee prostheses in vivo. This review examines the role of surface topography, third-body ...
Wear particle analysis and the evolution of the plastically deformed layer on Australian rail steel

Athukorala, Asitha C.; De Pellegrin, Dennis V.; Battaglia, Ben T.; Kourousis, Kyriakos I. (Trans Tech Publications, 2016)

Particle analysis methodology is presented, together with the morphology of the wear debris formed during rolling contact fatigue. Wear particles are characterised by their surface topography and in terms of wear mechanism. ...
Winging it: key issues and perceptions around regulation and practice of aircraft maintenance in australian general aviation

Naweed, Anjum; Kourousis, Kyriakos I. (MDPI, 2020)

The very diverse character of General Aviation (GA) within Australia poses challenges for its e ective management of risk and safety in the sector. Improvements for human performance and perceptions of safety within the ...
Xenogenic extracellular matrices as potential biomaterials for reconstruction of the urinary bladder.

Davis, Niall Francis (University of Limerick, 2011)

Surgical repair for end stage bladder disease often utilises vascularised, autogenous, mucus-secreting gastrointestinal tissue to either replace the diseased organ or to augment inadequate bladder tissue. Postoperatively, ...
Zeolite combined with alum and polyaluminum chloride mixed with agricultural slurries reduces carbon losses in runoff from grassed soil boxes

Fenton, O.; Murnane, John G.; Brennan, R.B.; Healy, Mark G.; Fenton, O. (American Society of Agronomy/ Soil Science Society of America, 2016)

Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products, which are potentially harmful to human health. This study ...
Zinc binding to S100B affords regulation of trace metal homeostasis and excitotoxicity in the brain

Hagmeyer, Simone; Cristóvão, Joana S.; Mulvihill, John J.E.; Boeckers, Tobias M.; Gomes, Cláudio M.; Grabrucker, Andreas M. (Frontiers Media, 2018)

Neuronal metal ions such as zinc are essential for brain function. In particular synaptic processes are tightly related to metal and protein homeostasis, for example through extracellular metal-binding proteins. One such ...
