Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
Pathak, Ashish; Healy, Mark G.; Morrison, Liam (Taylor & Francis, 2018-06-05)Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental ... -
Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
Fox, S.; Clifford, Eoghan (American Society of Civil Engineers, 2018-06-12)There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ... -
Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
O’ Flynn, Cornelius J.; Fenton, Owen; Wall, David; Brennan, Raymond B.; McLaughlin, Mike J.; Healy, Mark G. (Wiley, 2017-12-13)Cost effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with ... -
Interpretation of pipe-jacking and lubrication records for drives in silty soil
O'Dwyer, Kevin G.; McCabe, Bryan A.; Sheil, Brian B. (Elsevier, 2019-04-22)In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas, and other utilities) to avoid on-street disruption in urban areas. ... -
Lifecycle environmental and economic performance of nearly zero energy buildings (NZEB) in Ireland
Goggins, Jamie; Moran, Paul; Armstrong, Alan; Hajdukiewicz, Magdalena (Elsevier, 2016-01-16)Directives in the European Union are ensuring that buildings in this region are moving towards nearly zero energy buildings (NZEB). For countries like Ireland, which has a temperate oceanic climate, a key to achieving NZEB ... -
ModSCO. Online Reduced Order Models (ROM) to address the performance gap
Piccinini, Alessandro; Blanes, Luis M.; Seri, Federico; D'Angelo, Letizia; Keane, Marcus M. (MDPI, 2019-07-25)This communication presents ModSCO, a web application that supports systematic energy performance evaluation using Reduced Order Models (ROM). These models are particularly useful in scenario with missing, incomplete or ... -
A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
Callery, Oisín; Healy, Mark G. (Elsevier, 2019-07-02)Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ... -
A novel reduced order model technology framework to support the estimation of the energy savings in building retrofits
Piccinini, Alessandro; Hajdukiewicz, Magdalena; Keane, Marcus M. (Elsevier, 2021-03-13)Energy Performance Contracting (EPC), as a tool to enhance energy efficiency of buildings, can accelerate investment in cost-effective energy conservation measures (ECMs) for existing buildings. However, there are many ... -
A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
Ó Murchú, Cathal; Leen, Sean B.; O’Donoghue, Padraic E.; Barrett, Richard A. (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 ...
