Evaluating the structural capacity of concrete elements through in-situ instrumentation
(2013)The difficulty in predicting the long term load capacity of concrete elements is well documented. Time dependent effects such as creep and shrinkage coupled with varying loading events, particularly during construction, ... -
Evaluation of amendments to control phosphorus losses in runoff from dairy soiled water.
(Springer, 2011-12-01)Amendments with the potential to reduce phosphorus (P) losses from agricultural grassland arising from the land application of dairy-soiled water (DSW) were investigated. Optimal application rates were studied, and associated ... -
Evaluation of chemical amendments to control phosphorus losses from dairy slurry
(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 ... -
Evaluation of chemical amendments to control phosphorus losses from dairy slurry.
(Soil Use and Management, 2011-06-01)The aim of this paper is to identify chemicals with the potential to reduce P losses from agricultural grassland arising from the land application of dairy cattle slurry. It also aims to identify optimal application rates ... -
Evaluation of the fertiliser replacement value of phosphorus-saturated filter media
(Elsevier, 2021-01-12)The use of filter media to adsorb phosphorus (P) from nutrient-rich waters is an effective, simple and low-cost method to recover and reuse P as an inorganic fertiliser replacement. Although it is assumed that the saturated ... -
An evaluation of the general composition and critical raw material content of bauxite residue in a storage area over a twelve-year period
(Elsevier, 2018-10-09)Bauxite residue, the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150 million tonnes per annum. Currently, the reuse of bauxite residue is low (∼2%), due to ... -
Evaluation of the mechanical behaviour of novel latticed LVL-webbed joists
(Bentham Open, 2019-01-23)The mechanical behaviour of a novel I-joist having a latticed Laminated Veneer Lumber (LVL) web is investigated. A total of 30 joists with C24 Grade flanges and latticed LVL webs were manufactured and tested to failure. ... -
An evaluation of the performance and optimization of a new wastewater treatment technology: the air suction flow-biofilm reactor
(Taylor & Francis, 2014-12-09)In this laboratory study, a novel wastewater treatment technology, the air suction flow-biofilm reactor (ASF-BR) - a sequencing batch biofilm reactor technology with a passive aeration mechanism - was investigated for its ... -
Evidence of stabilised peat as a net carbon sink
(American Society of Civil Engineers, 2019-01-09)Mass stabilization, a ground improvement solution used for construction in peatlands, involves mixing suitable dry binders into the peat, increasing strength and stiffness and reducing permeability. A previous pilot study ... -
Examination of homogeneity of selected Irish pooling groups
(2010)In regional flood frequency estimation, a homogeneous pooling group of sites leads to a reduction in the error of quantile estimators which is the main aim of a regional flood frequency analysis. Examination of the homogeneity ... -
An examination of maximum legal application rates of dairy processing and associated STRUBIAS fertilising products in agriculture
(Elsevier, 2021-10-09)The dairy industry produces vast quantities of dairy processing sludge (DPS), which can be processed further to develop second generation products such as struvite, biochars and ashes (collectively known as STRUBIAS). These ... -
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)The use of fast-grown timber in the manufacture of engineered wood products is increasing; however, the fast growth rate results in a low-density timber that is susceptible to significant swelling and shrinkage deformations ... -
Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood fasteners
(Elsevier, 2021-09-16)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Experimental investigation of the moment-rotation behaviour of beam-column connections produced using compressed wood connectors
(Elsevier, 2022-04-04)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland
(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 ... -
Field assessment of coconut-based activated carbon systems for the treatment of herbicide contamination
(Elsevier, 2023-12-03)Once released into the environment, herbicides can move through soil or surface water to streams and groundwater. Filters containing adsorbent media placed in fields may be an effective solution to herbicide loss in the ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(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 ... -
Flipped learning in a civil engineering module: student and instructor experiences
(Irish Learning Technology Association, 2018-08-24)Flipped learning is a form of active learning in which the basic content is assimilated before scheduled classroom sessions, enabling more productive use of classroom time to cultivate problem-solving ability, a key ... -
