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. ... -
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 ... -
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 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 ... -
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 ... -
Interactive water services: The WATERNOMICS approach
(Elsevier, 2014-12-17)WATERNOMICS focuses on the development of ICT as an enabling technology to manage water as a resource, increase end-user conservation awareness and affect behavioral changes. Unique aspects of WATERNOMICS include personalized ... -
Interpretation of pipe-jacking and lubrication records for drives in silty soil
(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. ... -
Investigating the suitability of synthetic envelopes as an alternative or complement to stone aggregate in clay-textured soils in Ireland
(Elsevier, 2022-12-21)In Ireland, agricultural landscapes dominated by high rainfall and poorly drained soils have high densities of in-field pipe drains surrounded by stone aggregate envelopes. Unlike other countries, there is limited availability ... -
An investigation into the growth of lolium perenne L. and soil properties following soil amendment with phosphorus-saturated bauxite residue
(Springer, 2022-04-07)Industrial by-products, such as bauxite residue, may be used to treat phosphorus (P)-enriched water and wastewater. Once fully saturated, they may be reused as P fertilisers. This study aimed to investigate the effectiveness ... -
Investigation of the seismic performance of braced frames through both testing and analysis
(2008)The results of shake table tests on three concentrically-braced sub-frames are compared with a series of correlative inelastic analyses. Both transient time-history and nonlinear static (pushover) analyses are considered. ... -
