Mechanical properties of compressed wood
(Elsevier, 2021-08-03)Wood is a natural composite material. However, its relatively low mechanical properties restrict the use in advanced structural applications but recent studies have shown that Compressed Wood (CW), with superior mechanical ... -
The mechano-sorptive creep behaviour of basalt FRP reinforced timber elements in a variable climate
(Elsevier, 2019-09-25)The use of Fibre Reinforced Polymer (FRP) reinforcement has been shown to improve the short-term flexural behaviour of timber elements. This is particularly important when reinforced elements are subjected to a variable ... -
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
(Elsevier ScienceDirect, 2015-11-25)Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ( biosolids ), it is important to characterise such wastes beyond current regulated parameters. Concerns may be ... -
A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation
(De Gruyter Open, 2016-12-30)During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures, is challenging. This study establishes a methodological framework to identify appropriate experimental ... -
Methodology for the location of a subsurface permeable reactive barrier for the remediation of point source pollution on an Irish farm
(Teagasc, 2008-09)Nutrient loss from agricultural sources to water continues to be a national challenge. Diffuse pollution from agricultural sources is considered to be the primary cause of slight-to-moderate water pollution in Ireland, but ... -
Microbiological characterisation and impact of suspended solids on pathogen removal from wastewaters in dairy processing factories
(Cambridge University Press, 2018-08-29)In this Research Communication we investigate the microbiological profile of 12 dairy wastewater streams from three contrasting Irish dairy processing factories to determine whether faecal indicators/pathogens were present ... -
Microplastics in sewage sludge: effects of treatment
(American Chemical Society, 2016-12-12)Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ... -
Mineral fertiliser equivalent value of dairy processing sludge and derived biochar using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Elsevier, 2022-08-20)As supply chains of chemical fertilisers become more precarious, raw or derived bio-based fertilisers (herein referred to as bio-fertilisers) from the dairy processing industry could be good alternatives. However, their ... -
Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ... -
Mitigation of ammonia and greenhouse gas emissions from stored cattle slurry using acidifiers and chemical amendments
(Elsevier, 2019-07-28)Cattle and cow slurry storage is a significant source of agricultural greenhouse gas (GHG) and ammonia (NH3) emissions. While acidification has been demonstrated to significantly reduce these emissions, a knowledge gap ... -
Model-based fault detection and diagnosis of air handling units: A comparison of methodologies
(Elsevier, 2014-12-26)This paper presents a comparison between two model based diagnostics methodologies that can be used to detect and diagnose various faults that occur in Air Handling Units. The process from model development to inference ... -
Modelling nutrient and chlorophyll_a dynamics in an Irish brackish waterbody
(Elsevier, 2004-01)This paper presents aspects of a research investigation into nutrient fluxes into and out of an important Irish estuary, Wexford Harbour, located in the southeast of Ireland. Details of the methodology applied, the data ... -

Modelling of fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-03-04)This paper presents a computational methodology for frictional contact mechanics of the pressure armour layer in flexible risers. This will allow, for the first time, quantification of key fretting variables, such as contact ... -
Modelling phytoplankton dynamics in a complex estuarine system
(2011)The primary objective of this research was to develop a generic methodology for numerical modelling of the water quality within estuarine systems; in particular, this research focused on modelling nutrient dynamics and ... -
Modelling stone column installation in an elasto-viscoplastic soil
(Taylor & Francis, 2014-12-31)The majority of numerical studies investigating stone column performance have used “wished-in-place” columns (no installation effects) in conjunction with elastoplastic soil models (no viscous effects). In the first part ... -
Modelling the effects of climate change on urban coastal-fluvial flooding
(IWA Publishing, 2020-01-23)In coastal floodplains, high river flows and high coastal water levels can result in extensive flooding. Twenty-first century climate change is expected to alter these flood mechanisms. In this study, a coastal city of ... -
Modelling the hygro-mechanical creep behaviour of FRP reinforced timber elements
(Elsevier, 2020-06-20)A fully coupled moisture-displacement finite element model has been developed to predict the viscoelastic, mechano-sorptive and swelling/shrinkage behaviour of FRP reinforced timber elements when stressed under long-term ... -
