Nutrient, metal and microbial loss in surface runoff following treated sludge and dairy cattle slurry application to an Irish grassland soil
(Elsevier, 2015)Treated municipal sewage sludge ( biosolids ) and dairy cattle slurry (DCS) may be applied to agricultural land as an organic fertiliser. This study investigates losses of nutrients in runoff water (nitrogen (N) and ... -
Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ... -
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ... -
Prediction of pile settlement using artificial neural networks based on standard penetration test data
(2009)In recent years artificial neural networks (ANNs) have been applied to many geotechnical engineering problems with some degree of success. With respect to the design of pile foundations, accurate prediction of pile settlement ... -
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 ... -
Shaft resistance of driven cast-in-situ piles in sand
(NRC Research Press, 2015-06-25)Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests ... -
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ... -
Stone column effectiveness in soils with creep: a numerical study
(Taylor & Francis, 2016-03-16)While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ... -
Stone column settlement performance in structured anisotropic clays: the influence of creep
(Elsevier, 2016-07-15)The recently developed elasto-viscoplastic Creep-SCLAY1S model has been used in conjunction with PLAXIS 2D to investigate the effectiveness of vibro-replacement in a creep-prone clay. The Creep-SCLAY1S model accounts for ... -
Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
(Elsevier, 2016-12-05)Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ... -
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ...
