Key performance indicators to explain energy & economic efficiency across water utilities, and identifying suitable proxies

Walker, Nathan L.; Williams, A Prysor; Styles, David (Elsevier, 2020)

Water companies consume up to 8% of global energy demand, at billions of dollars’ cost. Benchmarking of performance between utilities can facilitate improvements in efficiency; however, inconsistencies in benchmarking ...
The ladies' 4-week cycle challenge: experiences and insights

O'Connell, Aileen; Higgins, Ross; Cosgrove, Tom (Irish Transport Research Network, 2015)

Limerick was designated as Ireland’s National Smarter Travel demonstration area in 2012. Limerick Smarter Travel (LST), which aims to promote sustainable travel in the City and suburbs, is a partnership between the ...
A lattice Boltzmann approach to surfactant-laden emulsions

Mukherjee, Siddhartha; Berghout, Pieter; Van den Akker, Harry E.A. (Wiley Periodicals, Inc. on behalf of American Institute of Chemical Engineers, 2019)

We present a pseudopotential lattice Boltzmann method to simulate liquid–liquid emulsions with a slightly soluble surfactant. The model is investigated in 2-D, over a wide parameter space for a single, stationary, immiscible ...
Learning from incidents in aircraft maintenance and continuing airworthiness management: A systematic review

Clare, James Thomas; Kourousis, Kyriakos I. (Wiley, 2021)

The purpose of this systematic review is to highlight the salient elements of learning from incidents in the aircraft maintenance and continuing airworthiness management area. (is involved the review of more than 1,000 ...
Learning from incidents in airworthiness: a novel framework tool for safety analysis

Clare, James Thomas (University of Limerick, 2021)

Safe air travel is an expectation that we often invest little or no thought in. Fortunately, the industry has evolved to a stage where major air accidents are rare. Numerous lessons in aviation safety have unfortunately ...
Learning from incidents: A qualitative study in the continuing airworthiness sector

Clare, James Thomas; Kourousis, Kyriakos I. (MDPI, 2021)

Learning from incidents (LFI) is a useful approach when examining past events and developing measures to prevent ensuing recurrence. Although the reporting of incidents in the aircraft maintenance and continuing airworthiness ...
Legume-modified rotations deliver nutrition with lower environmental impact

Costa, Marcela P.; Reckling, Moritz; Chadwick, Dave; Rees, Robert M.; Saget, Sophie; Williams, Michael; Styles, David (Frontiers Media, 2021)

Introducing legumes to crop rotations could contribute toward healthy and sustainable diet transitions, but the current evidence base is fragmented across studies that evaluate specific aspects of sustainability and ...
Lies, damned lies and quality management systems: a pilot case study

Brooks, Tara; Spillane, John P. (ARCOM: Association of Researchers in Construction Management, 2017)

An externally accredited ISO 9001 Quality Management System is a prerequisite for tendering for many public-sector projects, leaving Small to Medium Enterprises little choice but to implement such a system. A link between ...
Loading on long span bridges in heavily trafficked areas

Quilligan, Michael; O'Brien, Eugene John (Civil Engineering Research Association of Ireland, 2020)

The critical traffic loading condition for long-span bridges is congestion when vehicles may be closely spaced together. Data on very high traffic flows is limited however, as induction loops which are typically used to ...
Loss of adenylyl cyclase 6 in leptin receptor-expressing stromal cells attenuates loading-induced endosteal bone formation

Riffault, Mathieu; Johnson, Gillian P.; Owen, Madeline M.; Javaheri, Behzad; Pitsillides, Andrew A.; Hoey, David A. (Wiley and Sons Ltd, 2020)

Bone marrow stromal/stem cells represent a quiescent cell population that replenish the osteoblast bone-forming cell pool with age and in response to injury, maintaining bone mass and repair. A potent mediator of stromal/stem ...
The martensite transformation in Ni-based coatings & bulk alloys

Clancy, Marie (University of Limerick, 2010)

This thesis examines the formation of martensite in Ni-based super-alloys in both an alloy-coating system and in the bulk alloy, NiPtAl. The alloy-coating study was designed to test the hypothesis that an extra layer of ...
Material waste in the Northern Ireland construction industry: on-site management causes and methods of prevention

Marinelli, Marina; Dolan, Matthew; Spillane, John P.; Konanahalli, Ashwini (ARCOM: Association of Researchers in Construction Management, 2014)

The construction industry in Northern Ireland is one of the major contributors of construction waste to landfill each year. The aim of this research paper is to identify the core on-site management causes of material waste ...
Maximising the potential use of ground granulated blast-furnace slag (GGBS) in cement: An Irish investigation

Higgins, Brendan; Curran, Michael; Spillane, John P. (2020)

The production of cement is estimated to account for around 8% of carbon dioxide (CO2) emissions worldwide, and the Irish construction industry yields fifteen million tonnes of CO2 annually. Measures must be employed to ...
Measurement and prediction of machining induced redistribution of residual stress in the aluminium alloy 7449

Robinson, J.S.; Tanner, David A.; Truman, C.E.; Wimpory, R.C. (Springer, 2011)

The residual stress distributions in two 7449 aluminium alloy rectilinear blocks have been determined using neutron diffraction. Heat treatment included cold water immersion quenching and a period of precipitation hardening. ...
Measurement of strain induced responses at femoral artery bypass graft junctions

Campbell, Tríona (University of Limerick, 2015)

Femoral artery bypass grafts have a predilection for failure at the distal anastomosis due to restenosis, within a short period of time, the cause of which has been attributed to altered haemodynamics. This study proposes ...
Mechanical and structural characterisation of the dural venous sinuses

Walsh, Darragh R.; Lynch, James J; O'Connor, David T.; Newport, David; Mulvihill, John J.E. (Nature Research, 2020)

The dural venous sinuses play an integral role in draining venous blood from the cranial cavity. As a result of the sinuses anatomical location, they are of signifcant importance when evaluating the mechanopathology of ...
Mechanical characterisation of composite materials with 3D woven reinforcement architectures

Obande, Winifred O. (University of Limerick, 2016)

The use of traditional two-dimensional (2D) fibre preforms can be associated with poor out-of-plane and interlaminar mechanical performance, particularly in response to impact loads. Such preforms comprise multiple plies ...
The mechanical responses of advecting cells in confined flow

Connolly, Sinéad Á.; Newport, David; McGourty, Kieran Denis (American Institute of Physics, 2020)

Fluid dynamics have long influenced cells in suspension. Red blood cells and white blood cells are advected through biological microchannels in both the cardiovascular and lymphatic systems and, as a result, are subject ...
Mechanically stimulated osteocytes promote the proliferation and migration of breast cancer cells via a potential CXCL1/2 mechanism

Dwivedi, Anushree; Kiely, Patrick A.; Hoey, David A. (Elsevier, 2021)

Bone represents the most common site for breast cancer metastasis. Bone is a highly dynamic organ that is constantly adapting to its biophysical environment, orchestrated largely by the resident osteocyte network. Osteocytes ...
A mechanistic model for particle breakage within agitated crystallization systems

Tyrrell, Rory (University of Limerick, 2019)

Throughout the field of particulate processing the application of modelling techniques to predict, optimize, or otherwise enhance processes is widespread. Perhaps the most common technique when it comes to modelling ...
