Understanding the complexities of building physics and human behaviour in achieving a nearly zero energy building
(NUI Galway, 2016-07-27)About 40% of the world’s energy consumption and approximately a third of greenhouse gas emissions are associated with buildings. As the percentage of new buildings relative to existing buildings is increasing at a rate ... -
Unsaturated behaviour of a stabilized marine sediment: A comparison of cement and GGBS binders
(Elsevier, 2018-09-21)In order to ascertain the contaminant-encapsulation potential of stabilized soil, an understanding of its unsaturated hydraulic behaviour, specifically the Soil Water Retention Curve (SWRC), is paramount. In this paper, ... -
Use of amendments in a peat soil to reduce phosphorus losses from forestry operations
(Elsevier, 2015-10-18)Forestry harvesting on peats is known to result in significant losses of soil phosphorus (P) to adjacent waters, and the issue is becoming an increasingly serious concern as peatland forest stocks mature and reach harvestable ... -
Use of carbon calculation tools for sustainable cycle network design
(NUI Galway, 2012)In recent years European cycling has undergone a renaissance with various initiatives including the establishment of EuroVelo and the proposed European trans-border cycling infrastructure. Significant advances on this ... -
The use of digital resources in civil engineering education: Enhancing student learning and achieving accreditation criteria.
(2012)The use of digital resources in higher education has risen significantly over the last ten years and will continue to do so for the foreseeable future. The challenge for educational instructors is in determining how to ... -
The use of digital resources in civil engineering education: student learning and achieving accreditation criteria
(Cambridge Scholars Publishing, 2012)The use of digital resources in higher education has risen significantly over the last ten years and will continue to do so for the foreseeable future. The challenge for educational instructors is in determining how to ... -
Use of industrial by-products and natural media to adsorb nutrients, metals and organic carbon from drinking water
(2015)Filtration technology is well established in the water sector but is limited by inability to remove targeted contaminants, found in surface and groundwater, which can be damaging to human health. This study optimises the ... -
The use of laboratory sand, soil and crushed-glass filter columns for polishing domestic-strength synthetic wastewater that has undergone secondary treatment
(Taylor & Francis, 2010)The aim of this study was to examine the performance of intermittently loaded, 150 mm-diameter stratified filter columns of 2 depths (0.65 and 0.375 m) comprising different media - sand, crushed glass and soil - in polishing ... -
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
(Springer Verlag, 2020-06-17)Key message Mechanical properties of small-diameter round timber from hardwood thinnings of common alder (Alnus glutinosa (L.) Gaertn.), European ash (Fraxinus excelsior L.), European birch (Betula pendula Roth. & Betula ... -
Use of nondestructive techniques for determination of tension parallel-to-grain properties of spruce
(USDA Forest Service Forest Products Laboratory (FPL), 2019-09-25)The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance ... -
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
(Elsevier, 2020-07-01)Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ... -
The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters
(Elsevier, 2019-04-19)Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ... -
Use of zeolite with alum and PAC amendments to mitigate runoff losses of P, N and suspended solids from agricultural wastes applied to land
(ASA, CSSA, and SSSA, 2015)Diffuse pollutant losses containing phosphorus (P), nitrogen (N) and suspended solids (SS) can occur when agricultural wastes are applied to soil. This study aimed to mitigate P, N and SS losses in runoff from grassed ... -
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ... -
User, self-inspection, and quality checks requirements
(BUILT2SPEC Consortium, 2016)This Deliverable D1.1 aims to analyse the context of construction projects across various countries of the EU (partners countries), to identify the stakeholders and their issues, and to imagine which answers will be ... -
Using image processing for determination of settled sludge volume
(IWA Publishing, 2018-07-12)Determination of the sludge volume index is key to describing the settling characteristics of sludge in the aeration process of wastewater treatment plants (WWTPs). The two core components of this calculation are the settled ... -
