Erodibility of hill peat
(Teagasc, 2006-06-30)The energy necessary to entrain soil in water depends on the soil strength. Once entrained, the settling velocity of the eroded soil in water is of fundamental importance to the processes of sediment transport and deposition. ... -
Estimation of Maximum Biosolids and Meat and Bone Meal Application to a Low P Index Soil and a Method to Test for Nutrient and Metal Losses
(2013)The aim of this study was to develop (1) a method for the calculation of the maximum legal rate at which meat and bone meal (MBM) and biosolids should be applied to land, which took into account the soil phosphorus (P) ... -
Evaluating long-term performance of low-cost adsorbents using small-scale adsorption column experiments
(Elsevier, 2016-05-31)This study investigated a novel method of predicting the long-term phosphorus removal performance of large-scale adsorption filters, using data derived from short-term, small-scale column experiments. The filter media ... -
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 ... -
Evaluation of the structural behaviour of beam-beam connection systems using compressed wood dowels and plates
(NUI Galway, 2018-08-20)To support the transition to a bio-based society, it is preferable to substitute metallic fasteners and adhesives in timber construction with an eco-friendly alternative. Recent studies have identified compressed wood ... -
Evaluation of various turbulence models to predict indoor conditions in a naturally ventilated room
(2013)In recent years, Computational Fluid Dynamics (CFD) has become a popular tool in building simulation. However, developing reliable CFD models requires a high level of expertise in fluid dynamics and numerical techniques. ... -
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 ... -
Experiences of dry soil mixing in organic soils
(Institution of Civil Engineers, 2012)Soil mixing, or soil stabilisation, is a method of enhancing the geotechnical properties of suitable host soil through the addition of cementitious and/or pozzolanic binders in either dry or slurry forms. In dry soil mixing, ... -
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 ... -
