(National University of Ireland Galway, 2020-09-21)This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a ResistorCapacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings ... -
Recovered wood as raw material for structural timber products. Characteristics, situation and study cases: Ireland and Spain
(International Society of Wood Science and Technology (SWST), 2020-07-12)The circular economy is an efficient system to reuse materials reducing the amount of waste generated. In order to implement it in the timber sector, the InFutUReWood (Innovative Design for the Future Use and Reuse of ... -
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
(Elsevier, 2021-08-14)Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ... -
The role of wet wipes and sanitary towels as a source of white microplastic fibres in the marine environment
(Elsevier, 2020-06-10)Understanding source elements of the ocean plastic crisis is key to effective pollution reduction management and policy. The ubiquity of microplastic (MP) fibres in the oceans is considered to derive primarily from clothing ... -
Characterisation of Irish-grown Scots pine timber for structural applications
(National University of Ireland Galway, 2020-08-27)There is very little knowledge on the timber quality of the native Scots pine grown in Ireland, and its potential to produce timber for structural applications. This paper studied the mechanical performance in tension and ... -
Enhancing low grade sitka spruce glulam beams with bonded-in BFRP rods
(National University of Ireland Galway, 2014)The reinforcement of timber elements using fibre reinforced polymer (FRP) rods or plates is widely accepted as an effective method of increasing the stiffness of members, while at the same time reducing the variability ... -
Irish timber - characterisation, potential and innovation
(Civil Engineering Research Association of Ireland (CERAI), 2014-09-28)In order to increase the utilisation of Irish timber in construction and novel engineered wood products, the mechanical and physical properties of the material must be established. For timber products used for structural ... -
Mechano-sorptive creep in reinforced glulam
(National University of Ireland Galway, 2018-08-20)An investigation was carried out to examine the effect of reinforcement on the creep behaviour of FRP reinforced timber elements in a controlled variable climate. Creep is accelerated by moisture variations due to a ... -
Reinforcement of timber elements in compression perpendicular to the grain using compressed wood dowels
(National University of Ireland Galway, 2020-08-27)ABSTRACT: In the past decade, there has been an increased focus on the environmental impacts of construction and a movement towards more sustainable construction products. Timber is one such sustainable product that can ... -
Development and assessment of a blade element momentum theory model for high solidity vertical axis tidal turbines
(Elsevier, 2020-01-20)Tidal energy is an attractive renewable resource given its predictability. The production of reliable, efficient and cost-effective tidal energy turbines requires the development of computer models for assessment and design ... -
In-situ SEM study of fatigue micro-crack initiation and propagation behavior in pre-corroded AA7075-T7651
(Elsevier, 2020-04-18)Fatigue micro-cracking behavior in pre-corroded AA7075-T7651 is analyzed by in-situ scanning electron microscopy (SEM) observation and SEM-based fractography. The experimental results show that (i) fatigue microcracks ... -
Prediction of microstructure evolution for additive manufacturing of Ti-6Al-4V
(Elsevier, 2020-04-26)A key challenge for successful exploitation of additive manufacturing (AM) across a broad range of industries is the development of fundamental understanding of the relationships between process control and mechanical ... -
Stabilisation for peat improvement: Extent of carbonation and environmental implications
(Elsevier, 2020-06-13)The construction industry is a large contributor to global greenhouse gas emissions. In recent years, the industry has begun to consider sustainability alongside technical merit, cost and programme when analysing construction ... -
Optimal design and operation of small-scale wastewater treatment plants: The Irish case: EPA Research Report 255
(Environmental Protection Agency, 2018-08)There are many variables which must be considered when designing and operating a wastewater treatment system. The key objectives of this research were to develop software tools to assist in the selection and management of ... -
The effect of wastewater treatment processes, in particular ultraviolet light treatment, on pathogenic virus removal: EPA Research Report 171
(Environmental Protection Agency, 2016-05)Format: pdf Download now Municipal wastewater treatment plant discharges are a recognised source of human pathogenic viruses. Of concern within this group is norovirus the leading cause of viral gastroenteritis ... -
Increasing resource efficiency in wastewater treatment plants: EPA Research Report 168
(Environmental Protection Agency, 2016-03)The focus of this project was the resource efficiency of Irish wastewater treatment plants (WWTPs). The perspective of the report is both operational (economic) and environmental. Wastewater treatment is a resource-intensive ... -
