Holistic evaluation of field-scale denitrifying bioreactors as a basis to improve environmental quality.
(Association of Crop, Soil and Environmental Societies (ACSES), 2015-10-02)Denitrifying bioreactors effectively convert nitrate-nitrogen (NO3-N) to di-nitrogen and thereby protect water quality in agricultural landscapes. In the present study, the performance of a pilot-scale bioreactor (50 m ... -
How accurate are Energy Performance Certificates indicated energy savings of building retrofits?
(NUI Galway, 2016-08-29)With the impending nearly zero energy building (NZEB) regulations for residential new builds and retrofits for the European Union (EU) housing stock and the percentage of new buildings relative to existing buildings is ... -
The Impact of Biochar Addition on Nutrient Leaching and Soil Properties from Tillage Soil Amended with Pig Manure
(Springer, 2014-02)The application of pig manure to a tillage soil can result in pollution of surface and groundwater bodies. Countries in the European Union are required to comply with the Water Framework Directive, which states that all ... -
Impact of biochar addition to soil on greenhouse gas emissions following pig manure application
(2013)The application of biochar produced from wood and crop residues, such as sawdust, straw, sugar bagasse and rice hulls, to highly weathered soils under tropical conditions has been shown to influence soil greenhouse gas ... -
The impact of chemical amendment of dairy cattle slurry before land application on soil phosphorus dynamics
(Taylor and Francis, 2014-08-22)Application of dairy cattle slurry to agricultural soils, particularly those with high phosphorus (P) status or vulnerability to runoff, can increase P loss to waterbodies, which may accelerate eutrophication. While the ... -
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil
(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 ... -
Impact of chemical amendment of dairy cattle slurry on phosphorus, suspended sediment and metal loss to runoff from a grassland soil.
(Science of the Total Environment, 2011-11-01)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 ... -
Impact of chemically amended pig slurry on greenhouse gas emissions, soil properties and leachate.
(2013)The effectiveness of chemical amendment of pig slurry to ameliorate phosphorus (P) losses in runoff is well studied, but research mainly has concentrated only on the runoff pathway. The aims of this study were to investigate ... -
The impact of service-learning on voluntary and community organizations in the west of Ireland
(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.
(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 ... -
Implications of applied best management practice for peatland forest harvesting
(Elsevier (ScienceDirect), 2013-12-20)Elevated levels of nutrients and suspended sediment (SS), and changes to other environmental parameters, are frequently associated with forestry harvesting (clearfelling) operations, and are indicative of the potentially ... -
An improved experimental test set-up to study the performance of granular columns
(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
(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 ... -
Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry.
(Elsevier, 2012-09)Chemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. ... -
The influence of heat transfer and storage in structural precast building components on indoor environments
(2014)Knowledge about the heat transfer and storage in concrete components of the building envelope is vital in evaluating the environmental and energy performance of buildings. Providing sufficient thermal mass of the building ... -
The influence of panel lay-up on the characteristic bending and rolling shear strength of CLT
(MDPI, 2018-08-21)The objective of this study was to characterise the behaviour of cross laminated timber (CLT) panels and the influence of the panel lay-up on the failure strength. Three different panel configurations of thickness, 60 ... -
Influence of seasonal circulation on flushing of the Irish Sea
(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 ... -
Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
(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 ... -
