Engineering in Communities Learning by Doing
Goggins, Jamie (2012)Purpose The purpose of this paper is to focus on a number of initiatives in civil engineering undergraduate programmes at the National University of Ireland, Galway (NUIG) that allow students to complete engineering ... -
Environmental impacts of milk powder and butter manufactured in the Republic of Ireland
Finnegan, William; Goggins, Jamie; Clifford, Eoghan; Zhan, Xinmin (Elsevier, 2016-11-11)The abolition of the milk quota system that was in place in Europe was abolished in 2015, which instigated an immediate increase in milk production in many European countries. This increase "will aid in addressing the ... -
Evaluation of chemical amendments to control phosphorus losses from dairy slurry
Brennan, Raymond B.; Rodgers, Michael; Healy, Mark G. (Wiley, 2011)Land application of dairy slurry can result in incidental losses of phosphorus (P) to runoff in addition to increased loss of P from soil as a result of a buildup in soil test P (STP). An agitator test was used to identify ... -
Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
Healy, Mark G. (Elsevier, 2009-07)Groundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydro-geological techniques. Nitrate-N ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
Sheil, Brian B.; McCabe, Bryan A. (Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
Ground heave induced by installing stone columns in clay soils
McCabe, Bryan A.; Kamrat-Pietraszewska, Daniela; Egan, Derek (ICE Publishing, 2013-12)Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ... -
Harvesting effects on biomass and nutrient retention in Phragmites australis in a free-water surface constructed wetland in western Ireland
Healy, Mark G.; Newell, J; Rodgers, M. (2007)The aim of this study was to examine the seasonal variation in biomass, total nitrogen (Tot-N) and total phosphorus (Tot-P) content of Phragmites australis in a 3-cell free-water surface (FWS) constructed wetland in western ... -
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil
Brennan, Raymond B.; Healy, Mark G. (2011)Emerging remediation technologies such as chemical amendment of dairy cattle slurry have the potential to reduce phosphorus (P) solubility and consequently reduce P losses arising from land application of dairy cattle ... -
The impact of service-learning on voluntary and community organizations in the west of Ireland
Healy, Mark G.; McIlrath, Lorraine (NUI Maynooth, 2014-04)The aim of this study was to investigate the impact of student volunteers on community organizations and to identify deficits in training within service learning modules which, if addressed, could enable community organizations ... -
Impacts of zeolite, alum and polyaluminium chloride amendments mixed with agricultural wastes on soil column leachate, and CO2 and CH4 emissions.
Murnane, John G.; Fenton, Owen; Healy, Mark G. (Elsevier, 2017-11-02)This study aimed to quantify leaching losses of nitrogen (N), phosphorus (P) and carbon (C), as well as carbon dioxide (CO2) and methane (CH4) emissions from stored slurry and from packed soil columns surface applied with ... -
An improved experimental test set-up to study the performance of granular columns
Black, J.; Sivakumar, V.; Madhav, M.R.; McCabe, Bryan A. (ASTM International, 2006-03)This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine ... -
Improving the Delivery of a Construction Management Study-Abroad Course in Ireland through Student Feedback
Goggins, Jamie (2012)International study abroad offers limitless opportunities for students to learn outside of the traditional university setting. By living and learning in a foreign country, the student's exposure to a different culture can ... -
Influence of seasonal circulation on flushing of the Irish Sea
Dabrowski, Tomasz; Hartnett, Michael T.; Olbert, Agnieszka Indiana (Elsevier ScienceDirect, 2009-12-16)We applied a three-dimensional general ocean and coastal circulation model to the Irish Sea in order to determine water renewal time scales in the region. The model was forced with meteorological data for 1995, a year with ... -
An integrated approach to trophic assessment of coastal waters incorporating measurement, modelling and water quality classification
Hartnett, Michael; Nash, Stephen; Olbert, Agnieszka Indiana (2012)Various protocols have been developed for trophic assessment of coastal waters but most incorporate single value compliance criteria for water quality parameters which, in reality, exhibit significant spatial variation. ... -
Irish estuaries: Water quality status and monitoring implications under the water framework directive
Hartnett, Michael; Nash, Stephen (2011)The status of water quality of Irish estuaries is reviewed; this sheds light on the rationale behind the design of the national monitoring programme. Relative to other EU Member States, Ireland's coastal monitoring programme ... -
A laboratory study of the expansion of an Irish pyritic mudstone/siltstone fill material
Sutton, David; McCabe, Bryan A.; O'Connell, Aidan; Cripps, John C. (Elsevier, 2012-11-07)Extensive damage to dwellings in the east of Ireland, arising from the expansive pyritic fill material used beneath the floor slabs, prompted the laboratory study presented in this paper to quantify the expansion and study ... -
Linear irregular wave generation in a numerical wave tank
Finnegan, William; Goggins, Jamie (Elsevier, 2015-07-09)In the design of any floating or fixed marine structure, it is vital to test models in order to understand the fluid/structure interaction involved. A relatively inexpensive method, compared to physical model testing, of ... -
