An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (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 ... -
Inactivation efficiency of Bacillus endospores via modified flow-through PUV treatment with comparison to conventional LPUV treatment
Fitzhenry, Kelly; Rowan, Neil; Val del Río, Ángeles; Cremillieux, A.; Clifford, Eoghan (Elsevier, 2018-11-28)Water is a fragile resource, consequently there is a pressing need to develop sustainable environmental-friendly disinfection technologies. This constitutes the first study to compare efficacy of continuous low-pressure ... -
The influence of age on the timber properties and grading of Scots pine and larch in Ireland
Gil-Moreno, David; Manso, Rubén; O’Ceallaigh, Conan; Harte, Annette M. (Oxford University Press, 2023-06-13)Scots pine (Pinus sylvestris L.) and larch (Larix spp.) are two species that could contribute to diversifying Ireland’s timber supply. However, there is little knowledge about their properties as well as their variation ... -
The influence of panel lay-up on the characteristic bending and rolling shear strength of CLT
O'Ceallaigh, Conan; Sikora, Karol; Harte, Annette M. (MDPI, 2018-08-21)The objective of this study was to characterise the behaviour of cross laminated timber (CLT) panels and the influence of the panel lay-up on the failure strength. Three different panel configurations of thickness, 60 ... -
An investigation of the viscoelastic creep behaviour of basalt fibre reinforced timber elements
Conan O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (Elsevier, 2018-08-01)An investigation was carried out to examine the effect of flexural reinforcement on the long-term behaviour of timber beams. Creep tests, utilising statistically matched groups, were performed under Service Class 1 conditions ... -
Microbiological characterisation and impact of suspended solids on pathogen removal from wastewaters in dairy processing factories
Fitzhenry, Kelly; Rowan, Neil; Finnegan, William; Zhan, Xinmin; Clifford, Eoghan (Cambridge University Press, 2018-08-29)In this Research Communication we investigate the microbiological profile of 12 dairy wastewater streams from three contrasting Irish dairy processing factories to determine whether faecal indicators/pathogens were present ... -
Mitigation of ammonia and greenhouse gas emissions from stored cattle slurry using acidifiers and chemical amendments
Kavanagh, I.; Burchill, W.; Healy, Mark G.; Fenton, O.; Krol, D. J.; Lanigan, G. J. (Elsevier, 2019-07-28)Cattle and cow slurry storage is a significant source of agricultural greenhouse gas (GHG) and ammonia (NH3) emissions. While acidification has been demonstrated to significantly reduce these emissions, a knowledge gap ... -
Modelling the hygro-mechanical creep behaviour of FRP reinforced timber elements
O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (Elsevier, 2020-06-20)A fully coupled moisture-displacement finite element model has been developed to predict the viscoelastic, mechano-sorptive and swelling/shrinkage behaviour of FRP reinforced timber elements when stressed under long-term ... -
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
Llana, Daniel F.; Short, Ian; Harte, Annette M. (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 ...
