Life cycle assessment of fish and seafood processed products – A review of methodologies and new challenges
(Elsevier, 2020-12-14)Life cycle assessment (LCA) has been widely applied in many different sectors, but the marine products and seafood segment have received relatively little attention in the past. In recent decades, global fish production ... -
Life cycle assessment of sitka spruce forest products grown in Ireland
(Springer, 2023-08-28)Purpose The purpose of this study is to quantify the environmental impacts of Sitka spruce timber products harvested from the forestry sector in Ireland. This data is typically country-specific and is required to accurately ... -
Lifecycle environmental and economic performance of nearly zero energy buildings (NZEB) in Ireland
(Elsevier, 2016-01-16)Directives in the European Union are ensuring that buildings in this region are moving towards nearly zero energy buildings (NZEB). For countries like Ireland, which has a temperate oceanic climate, a key to achieving NZEB ... -
Linear irregular wave generation in a numerical wave tank
(Elsevier, 2015-07-09)In the design of any floating or fixed marine structure, it is vital to test models in order to understand the fluid/structure interaction involved. A relatively inexpensive method, compared to physical model testing, of ... -
Liquid phase optimisation in a horizontal flow biofilm reactor (HFBR) technology for the removal of methane at low temperatures
(Elsevier, 2014-01-03)Methane (CH4) is a potent greenhouse gas often emitted in low concentrations from waste sector activities. Biological oxidation techniques have the potential to offer effective methods for the remediation of such emissions. ... -
Liquid phase optimisation in a horizontal flow biofilm reactor (HFBR) technology for the removal of methane at low temperatures.
(2013-03)In this study, methods of improving the methane oxidation performance of a biofilm technology, the horizontal flow biofilm reactor (HFBR), operated at low temperatures were investigated. Three pilot scale HFBRs were ... -
Long-term inter-annual variability of a cyclonic gyre in the western Irish Sea
(Elsevier ScienceDirect, 2011-05-26)The western Irish Sea gyre (WISG) is a cyclonic baroclinic flow around a dome of stagnant water which develops each year during the heating season in the western Irish Sea. Research was carried out to determine long-term ... -
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 ...
