The assessment of embodied energy in typical reinforced concrete building structures in Ireland
(2010)This paper demonstrates that by understanding how energy is consumed in the manufacturing of reinforced concrete, designers can significantly reduce the overall embodied energy of structures. Embodied energy of products ... -
Assessment of intermittently loaded woodchip and sand filters to treat dairy soiled water
(IWA Publishing and Elsevier, 2016-07-31)Land application of dairy soiled water (DSW) is expensive relative to its nutrient replacement value. The use of aerobic filters is an effective alternative method of treatment and potentially allows the final effluent to ... -
Assessment of Tc-99 monitoring within the western Irish Sea using a numerical model
(Elsevier ScienceDirect, 2010-05-26)Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute ... -
Behaviour of tubular steel members under cyclic axial loading
(2006)This paper examines the cyclic performance of axially-loaded tubular members used as bracing elements to provide lateral seismic resistance in steel framed structures. An experimental study into the response of members ... -
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
(Elsevier ScienceDirect, 2016-05-09)The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ... -
Calibrated CFD simulation to evaluate thermal comfort in a highly-glazed naturally ventilated room
(2013)Natural ventilation is a sustainable solution to maintaining healthy and comfortable environmental conditions in buildings. However, the effective design, construction and operation of naturally ventilated buildings require ... -
Carbon and nitrogen dynamics and greenhouse gas emissions in constructed wetlands treating wastewaters: a review
(2016-02-17)The removal efficiency of carbon (C) and nitrogen (N) in constructed wetlands (CWs) is very inconsistent and frequently does not reveal whether the removal processes are due to physical attenuation or whether the different ... -
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
(2011)The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ... -
Chemical amendment of pig slurry: control of runoff related risks due to episodic rainfall events up to 48 hours after application.
(2013)Losses of phosphorus (P) from soil and slurry during episodic rainfall events can contribute to eutrophication of surface water. However, chemical amendments have the potential to decrease P and suspended solids (SS) losses ... -
Comparison of a stratified and a single-layer laboratory sand filter to treat dairy soiled water from a farm-scale woodchip filter
(Springer, 2014-04)Washing-down parlours and standing areas, following milking on dairy farms, produces dairy soiled water (DSW) that contains variable concentrations of nutrients. Aerobic woodchip filters can remove organic matter, nutrients ... -
Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates.
(Elsevier, 2014-10-13)The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. ... -
Constructed wetlands for the treatment of highway runoff.
(Nova Publishers, 2008-06-01)Highway surface runoff contains pollutants such as total suspended solids (TSS), hydrocarbons, de-icing salts, and heavy metals. Treatment methods for highway runoff include storage/treatment facilities, such as constructed ... -
The creation of a living laboratory for structural engineering at the National University of Ireland, Galway
(2012)The recently completed New Engineering Building (NEB) at the National University of Ireland, Galway (NUIG) is a new state of the art academic facility on the university's north campus. The building unites all five ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads
(Elsevier, 2009)This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads.
(Construction and Building Materials, 2009-06-01)This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ... -
Cyclic performance of steel and composite bracing members
(2005)This paper describes an experimental study on the response of hollow and filled steel members to monotonic and cyclic axial loading. Monotonic tests were first performed on short specimens to establish their compressive ... -
Denitrification of a nitrate-rich wastewater using various wood-based media materials
(2006)This laboratory study examined the use of various wood materials as a carbon source in horizontal flow filters to denitrify nitrate-nitrogen (NO3-N) from a synthetic wastewater. The filter materials were: sawdust ( Pinus ... -
Determination of flushing characteristics of the Irish Sea: A spatial approach
(Elsevier ScienceDirect, 2011-12-08)The Authors devised a novel generic approach to assessing the flushing of the Irish Sea through the determination of spatially distributed residence times and the development of flushing homogeneity curves. Results indicate ... -
Development of a nested coastal circulation model: boundary error reduction
(Elsevier, 2014-03)Numerical models have a valuable role to play in the sustainable management of coastal waters but accurate simulation of land/sea interactions, particularly in areas of complex coastlines, requires the use of high spatial ... -
