Management and rehabilitation of peatlands: the roles of water chemistry, hydrology, policy, and emerging monitoring methods to ensure informed decision making
(Elsevier, 2022-04-03)As the world's most abundant source of terrestrial carbon, peatlands provide numerous ecosystem services, including habitat biodiversity and freshwater quality. Land and water management practices in relation to peatlands, ... -
Mass timber - the emergence of a modern construction material
(Taylor & Francis, 2017-08-31)In the move towards sustainable construction, timber and wood-based products are becoming increasingly important structural materials. The introduction of mass timber products with excellent load carrying characteristics ... -
Measured and predicted t-z curves for a driven pile in lightly overconsolidated silt
(National University of Ireland Galway, 2008-04-03)Data from a static compression load test on a single driven pile in a lightly overconsolidated silt are presented in this paper. The pile was equipped with vibrating wire strain gauges along its length enabling its load ... -
Mechanical characterisation of green Sitka spruce logs
(NUI Galway, 2016-08-29)ABSTRACT: Timber is by its nature a very heterogeneous material. Many different factors impact its mechanical properties, from tree species to environment (climate, competition, soil…). While a number of studies in the ... -
Mechanical properties estimation by non-destructive testing of Irish hardwood round timber from thinnings for construction purposes
(Department of Forestry Policy and Economics, University of Sopron, Hungary, 2018-10-25)Thinning involves the removal of competitors of high quality trees, and trees for extraction racks, all to favour the growth of the selected trees. Many felled trees are small-diameter and in Ireland hardwood thinnings are ... -
Mechanical properties of compressed wood
(Elsevier, 2021-08-03)Wood is a natural composite material. However, its relatively low mechanical properties restrict the use in advanced structural applications but recent studies have shown that Compressed Wood (CW), with superior mechanical ... -
Mechanisms of flooding in Cork City
(International Association of Hydrological Sciences, 2015-11-17)Flooding is one of the most frequent and devastating natural disasters. Many urban developments are located in estuaries where river flow and sea water merge. Cork City situated in the River Lee estuary frequently subject ... -
The mechano-sorptive creep behaviour of basalt FRP reinforced timber elements in a variable climate
(Elsevier, 2019-09-25)The use of Fibre Reinforced Polymer (FRP) reinforcement has been shown to improve the short-term flexural behaviour of timber elements. This is particularly important when reinforced elements are subjected to a variable ... -
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 ... -
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
(Elsevier ScienceDirect, 2015-11-25)Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ( biosolids ), it is important to characterise such wastes beyond current regulated parameters. Concerns may be ... -
A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation
(De Gruyter Open, 2016-12-30)During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures, is challenging. This study establishes a methodological framework to identify appropriate experimental ... -
Methodology for quality checks for energy efficient buildings
(NUI Galway, 2017-03-01)The built environment accounts for more than 40% of the overall energy consumption and 36% of the overall CO2 emissions in Europe. Moreover, statistics show that construction and the upkeep of European buildings and ... -
Methodology for the location of a subsurface permeable reactive barrier for the remediation of point source pollution on an Irish farm
(Teagasc, 2008-09)Nutrient loss from agricultural sources to water continues to be a national challenge. Diffuse pollution from agricultural sources is considered to be the primary cause of slight-to-moderate water pollution in Ireland, but ... -
Microbiological characterisation and impact of suspended solids on pathogen removal from wastewaters in dairy processing factories
(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 ... -
Microplastics in sewage sludge: effects of treatment
(American Chemical Society, 2016-12-12)Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ... -
Mineral fertiliser equivalent value of dairy processing sludge and derived biochar using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Elsevier, 2022-08-20)As supply chains of chemical fertilisers become more precarious, raw or derived bio-based fertilisers (herein referred to as bio-fertilisers) from the dairy processing industry could be good alternatives. However, their ... -
Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ... -
Mitigation of ammonia and greenhouse gas emissions from stored cattle slurry using acidifiers and chemical amendments
(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 ... -
Model-based fault detection and diagnosis of air handling units: A comparison of methodologies
(Elsevier, 2014-12-26)This paper presents a comparison between two model based diagnostics methodologies that can be used to detect and diagnose various faults that occur in Air Handling Units. The process from model development to inference ... -
