A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
(SAGE Publications, 2018-04-04)A multiaxial, physically based, continuum damage mechanics methodology for creep of welded 9Cr steels is presented, incorporating a multiple precipitate-type state variable, which simulates the effects of strain- and ... -
Predicting the propagation of concentration and saturation fronts in fixed-bed filters
(IWA Publishing, 2017-07-05)The phenomenon of adsorption is widely exploited across a range of industries to remove contaminants from gases and liquids. Much recent research has focused on identifying low-cost adsorbents which have the potential to ... -
Prediction of pile settlement using artificial neural networks based on standard penetration test data
(2009)In recent years artificial neural networks (ANNs) have been applied to many geotechnical engineering problems with some degree of success. With respect to the design of pile foundations, accurate prediction of pile settlement ... -
Production of polyhydroxybutyrate by activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)In this study, polyhydroxybutyrate (PHB) 'a biodegradable plastics material' was produced by activated sludge performing enhanced biological phosphorus removal (EBPR) in batch experiments under anaerobic, aerobic and ... -
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ... -
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
(Elsevier, 2019-12-17)Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ... -
Quantification of heat losses through building envelope thermal bridges influenced by wind velocity using the outdoor infrared thermography technique
(Elsevier, 2017-09-18)Improving the thermal performance of the existing building stock is essential to significantly reduce the overall energy consumption in the building sector. A key objective is the retrofitting of the existing building ... -
A quantitative microbial risk assessment model for total coliforms and e. coli in surface runoff following application of biosolids to grassland
(Elsevier, 2017-03-06)In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is ... -
Quantitative risk assessment of antimicrobials in biosolids applied on agricultural land and potential translocation into food
(Elsevier, 2017-12-30)The use of biosolids as a fertiliser may be an indirect route for contaminants into the food chain. One of the main concerns regarding the spreading of biosolids on agricultural land is the potential uptake of contaminants ... -
Real-time monitoring framework to investigate the environmental and structural performance of buildings
(Elsevier ScienceDirect, 2014-12-20)Energy provides safety, comfort and mobility to people, and is essential for industrial, commercial and societal growth. However, generation and consumption of energy give rise of greenhouse gases and various air pollutants, ... -
Real-time monitoring to investigate structural performance of hybrid precast concrete educational buildings
(Taylor & Francis, 2016-11-22)The motivation and implementation of a real-time structural health monitoring strategy to determine the structural performance of a number of educational buildings recently constructed in Ireland is discussed in this paper. ... -
Regional modelling of the 21st century climate changes in the Irish Sea
(Elsevier, 2012-06)An assessment of the complex evolution of climate change signals in the Irish Sea over the 21st century is presented in this paper. Potential impacts of climate change on the local hydrography are explored and interrelationships ... -
Relationships between wood properties of small clear specimens and structural-sized boards in three softwood species
(De Gruyter, 2019-06-12)Research on the mechanical and physical properties of wood is commonly carried out on either small clear specimens or structural-sized boards. The first approach was more frequently utilised in the past, while the latter ... -
Repeated load testing of two schist and limestone aggregate materials used in unbound forest roads
(2009)This study examined the behaviour of two completion aggregates that were placed on a silty sandy formation material and subjected to repeated loading in a large-scale testing rig. The completion aggregates were (i) a good ... -
A review of field performance of stone columns on soft soils
(2009-12)The behaviour of stone columns has yet to be captured fully by analytical and numerical techniques, and predicting column behaviour in soft cohesive soils brings specific challenges. This paper provides a comprehensive ... -
A review of phosphorus and sediment release from Irish tillage soils, the methods used to quantify losses and the current state of mitigation practice.
(2012)Throughout the European Union (EU), agricultural soils with high phosphorus (P) status due to a surplus input of fertiliser have been identified as a landscape pressure impacting on water quality. In the Republic of Ireland, ... -
Review of state of the art dowel laminated timber members and densified wood materials as sustainable engineered wood products for construction and building applications
(Elsevier, 2019-12-10)Engineered Wood Products (EWPs) are increasingly being used as construction and building materials. However, the predominant use of petroleum-based adhesives in EWPs contributes to the release of toxic gases (e.g. Volatile ... -
A review study of water quality index models and their use for assessing surface water quality
(Elsevier, 2020-12-17)The water quality index (WQI) model is a popular tool for evaluating surface water quality. It uses aggregation techniques that allow conversion of extensive water quality data into a single value or index. Globally, the ... -
