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 ... -
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, ... -
Experimental investigation of the response of a driven pile in soft silt
(National University of Ireland Galway, 2004-12-01)The paper describes the results of field tests carried out using highly instrumented piles at a very soft estuarine clayey silt deposit at Kinnegar, Belfast. The site has been used for a number of years as a geotechnical ... -
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
(NUI Galway, 2018-08-29)European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ... -
Factors affecting Embodied Carbon/Embodied Energy associated with ground improvements techniques for construction on peat
(NUI Galway, 2012)In addition to the traditional drivers of cost and timely programme delivery, embodied energy (EE) and embodied carbon (EC) have emerged as major considerations in all aspects (including geotechnical) of large construction ... -
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 ... -
Flexural reinforcement of glue-laminated timber beams using prestressed FRP plates.
(NetComposites Limited, 2009-09-01)Fibre-reinforced polymer (FRP) plates have been used successfully to enhance the structural performance of glue-laminated (glulam) timber beams. Unreinforced glulams usually fail in tension in a brittle fashion. The addition ... -
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 ... -
Formal Calibration methodology for a CFD model of a naturally ventilated room
(2011)This paper describes a systematic methodology for the development of calibrated thermodynamic Computational Fluid Dynamics (CFD) models for controlled environments in buildings utilising wireless sensor networks. ... -
Formal calibration methodology for CFD model development to support the operation of energy efficient buildings
(Texas A&M University, 2010)Computational Fluid Dynamics (CFD) is a robust tool for modelling interactions within and between fluids and solids. CFD can help understand and predict phenomena that are difficult to test experimentally leading ... -
Formal calibration methodology for CFD models of naturally ventilated indoor environments
(Elsevier, 2012-08-31)Well planned natural ventilation strategies and systems in the built environments may provide healthy and comfortable indoor conditions, while contributing to a significant reduction in the energy consumed by buildings. ... -
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ... -
Future phosphorus: advancing new '2D' allotropes and growing a sustainable bio economy
(Crop Science Society of America with American Society of Agronomy and Soil Science Society of America, 2019-07-11)With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a new bioeconomy, which, at its core, tackles the current disparities and inequalities ... -
