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. ... -
Increasing resource efficiency in wastewater treatment plants: EPA Research Report 168
(Environmental Protection Agency, 2016-03)The focus of this project was the resource efficiency of Irish wastewater treatment plants (WWTPs). The perspective of the report is both operational (economic) and environmental. Wastewater treatment is a resource-intensive ... -
An Indoor Environmental Quality (IEQ) assessment of a partially-retrofitted university building
(Elsevier, 2018-05-07)Achieving standards-based Indoor Environmental Quality (IEQ) in existing buildings is growing steadily due to the strong demand for deep retrofits in Europe. Existing non-domestic buildings pose challenges mainly due to ... -
The influence of age on the timber properties and grading of Scots pine and larch in Ireland
(Oxford University Press, 2023-06-13)Scots pine (Pinus sylvestris L.) and larch (Larix spp.) are two species that could contribute to diversifying Ireland’s timber supply. However, there is little knowledge about their properties as well as their variation ... -
Influence of connection systems on serviceability response of CLT timber flooring
(TU Verlag Wien, 2016-08-22)In this paper finite element analysis of a five layer cross-laminated timber (CLT) rectangular floor is presented. The model was developed using 3D shell elements with linear elastic orthotropic material properties. Support ... -
The influence of crown and stem characteristics on timber quality in softwoods
(Elsevier, 2018-12-28)The relationships between several crown and tree properties and timber quality were examined on three softwood species: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) H. Karst) and Sitka ... -
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 ... -
Infrared thermography technique as an in-situ method of assessing heat loss through thermal bridging
(Elsevier, 2016-11-17)A key aspect in assessing the thermal standard of building envelopes is the quantification of the heat loss though thermal bridging, which can be expressed in terms of the linear thermal transmittance Psi. Values of W may ... -
Installation of a reduced-scale pile group in silt
(IHS BRE Press, 2008)This paper presents measurements of total stress and pore pressure made during and after the installation of a reduced scale group of five piles in a soft estuarine silt. The instrumentation includes pore pressure and ... -
Instrumented concrete pile tests – part 1: a review of instrumentation and procedures
(ICE Publishing, 2021-11-03)Preliminary pile tests are becoming increasingly routine in piling projects, some of which are instrumented to help optimise working pile design. However, the execution of a successful test on an instrumented concrete ... -
Instrumented concrete pile tests – part 2: strain interpretation
(ICE Publishing, 2021-11-03)The incorporation of strain gauges (traditionally electrical resistance and vibrating wire gauges but increasingly fibre optic sensors) within concrete piles enables an enhanced understanding of the shear stress distribution ... -
Instrumented single and group piles in Belfast soft clay
(Australian Geomechanics Society, 2000-12)The paper presents a number of key findings from an experimental pile test programme, which is currently underway at a soft clay test bed site on the outskirts of Belfast, Northern Ireland. These findings provide additional ... -
An integrated approach to trophic assessment of coastal waters incorporating measurement, modelling and water quality classification
(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. ... -
An integrated assessment of nitrogen source, transformation and fate within an intensive dairy system to inform management change.
(Public Library of Science, 2019-07-23)From an environmental perspective optimised dairy systems, which follow current regulations, still have low nitrogen (N) use efficiency, high N surplus (kg N ha-1) and enable ad-hoc delivery of direct and indirect reactive ... -
An integrated connectivity risk ranking for phosphorus and nitrogen along agricultural open ditches to inform targeted and specific mitigation management
(Frontiers Media, 2024-02-19)On dairy farms with poorly drained soils and high rainfall, open ditches receive nutrients from different sources along different pathways which are delivered to surface water. Recently, open ditches were ranked in terms ... -
