Production of polyhydroxybutyrate by activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)In this study, polyhydroxybutyrate (PHB) 'a biodegradable plastics material' was produced by activated sludge performing enhanced biological phosphorus removal (EBPR) in batch experiments under anaerobic, aerobic and ... -
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ... -
Quantification of heat losses through building envelope thermal bridges influenced by wind velocity using the outdoor infrared thermography technique
(Elsevier, 2017-09-18)Improving the thermal performance of the existing building stock is essential to significantly reduce the overall energy consumption in the building sector. A key objective is the retrofitting of the existing building ... -
A quantitative microbial risk assessment model for total coliforms and e. coli in surface runoff following application of biosolids to grassland
(Elsevier, 2017-03-06)In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is ... -
Quantitative risk assessment of antimicrobials in biosolids applied on agricultural land and potential translocation into food
(Elsevier, 2017-12-30)The use of biosolids as a fertiliser may be an indirect route for contaminants into the food chain. One of the main concerns regarding the spreading of biosolids on agricultural land is the potential uptake of contaminants ... -
Real-time control of occupants thermal comfort in buildings
(International Building Performance Simulation Association, 2015-12-07)Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings. Since, heating, ventilation and air ... -
Real-time monitoring and performance of retaining structures
(NUI Galway, 2014-08)The advent of reliable real-time monitoring devices has changed the way we monitor the construction of geotechnical infrastructure. This paper presents a case study where Shaped Accel Arrays (SAA) were employed as part ... -
Real-time monitoring framework to investigate the environmental and structural performance of buildings
(Elsevier ScienceDirect, 2014-12-20)Energy provides safety, comfort and mobility to people, and is essential for industrial, commercial and societal growth. However, generation and consumption of energy give rise of greenhouse gases and various air pollutants, ... -
Real-time monitoring of a hybrid precast and in situ concrete flat slab system
(2014)This paper presents a scheme developed for instrumentation and monitoring of the structural performance of a hybrid precast and in situ concrete flat slab system employed in an educational building. The system contains a ... -
Real-time monitoring to investigate structural performance of hybrid precast concrete educational buildings
(Taylor & Francis, 2016-11-22)The motivation and implementation of a real-time structural health monitoring strategy to determine the structural performance of a number of educational buildings recently constructed in Ireland is discussed in this paper. ... -
Regional modelling of the 21st century climate changes in the Irish Sea
(Elsevier, 2012-06)An assessment of the complex evolution of climate change signals in the Irish Sea over the 21st century is presented in this paper. Potential impacts of climate change on the local hydrography are explored and interrelationships ... -
Relationships between wood properties of small clear specimens and structural-sized boards in three softwood species
(De Gruyter, 2019-06-12)Research on the mechanical and physical properties of wood is commonly carried out on either small clear specimens or structural-sized boards. The first approach was more frequently utilised in the past, while the latter ... -
Repeated load testing of two schist and limestone aggregate materials used in unbound forest roads
(2009)This study examined the behaviour of two completion aggregates that were placed on a silty sandy formation material and subjected to repeated loading in a large-scale testing rig. The completion aggregates were (i) a good ... -
Residual load development in cast in place piles - a review and a new case history
(2012)The development of residual (or locked-in)loads in driven pre-formed piles has been investigated extensively over the past 40 years or so. In contrast, cast-in-situ piles are often erroneously assumed to be free of residual ... -
Retrofit solutions for Irish building stock: The impact of human behaviour
(NUI Galway, 2016)Retrofitting buildings is recognised as the most immediate, pressing, and cost effective mechanism to reduce energy consumption and carbon emissions in the building and construction sector. It is necessary to double or ... -
A review of field performance of stone columns on soft soils
(2009-12)The behaviour of stone columns has yet to be captured fully by analytical and numerical techniques, and predicting column behaviour in soft cohesive soils brings specific challenges. This paper provides a comprehensive ... -
A review of phosphorus and sediment release from Irish tillage soils, the methods used to quantify losses and the current state of mitigation practice.
(2012)Throughout the European Union (EU), agricultural soils with high phosphorus (P) status due to a surplus input of fertiliser have been identified as a landscape pressure impacting on water quality. In the Republic of Ireland, ... -
A review of remediation and control systems for the treatment of agricultural wastewater in Ireland to satisfy the requirements of the Water Framework Directive
(RIA, 2008)In Ireland, agricultural activities have been identified as major sources of nutrient input to receiving waters and it has been estimated that these activities contribute 75.3% of the nitrogen (N) and 33.4% of the phosphorus ... -
Review: the environmental status and implications of the nitrate time lag in Europe and North America.
(Springer Verlag, 2017-08-14)The efficacy of water quality policies aiming to reduce or prevent nitrate contamination of waterbodies may be constrained by the inherent delay or Btime lag^ of water and solute transport through unsaturated (soil) and ...
