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 ...
Environmental impacts of milk powder and butter manufactured in the Republic of Ireland
(Elsevier, 2016-11-11)
The abolition of the milk quota system that was in place in Europe was abolished in 2015, which instigated an immediate increase in milk production in many European countries. This increase "will aid in addressing the ...
Impact of biochar addition to soil on greenhouse gas emissions following pig manure application
(2013)
The application of biochar produced from wood and crop residues, such as sawdust, straw, sugar bagasse and rice hulls, to highly weathered soils under tropical conditions has been shown to influence soil greenhouse gas ...
A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
(Elsevier, 2019-07-02)
Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ...
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 ...
Impacts of zeolite, alum and polyaluminium chloride amendments mixed with agricultural wastes on soil column leachate, and CO2 and CH4 emissions.
(Elsevier, 2017-11-02)
This study aimed to quantify leaching losses of nitrogen (N), phosphorus (P) and carbon (C), as well as carbon dioxide (CO2) and methane (CH4) emissions from stored slurry and from packed soil columns surface applied with ...
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 ...
A laboratory study of the expansion of an Irish pyritic mudstone/siltstone fill material
(Elsevier, 2012-11-07)
Extensive damage to dwellings in the east of Ireland, arising from the expansive pyritic fill material used beneath the floor slabs, prompted the laboratory study presented in this paper to quantify the expansion and study ...
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
(2011)
The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ...
Economic analysis of pig manure treatment options in Ireland.
(2012)
An economic analysis was performed on treatment options for pig manure in Ireland.
Costs were based on a 500 sow integrated pig farm producing 10,500 m3 of manure per
year at 4.8 % dry matter. The anaerobic digestion of ...
