(NRC Research Press, 2018-11-22)[No abstract available] -
Discussion: Interaction factor for large pile groups
(ICE Publishing, 2016-09-27)The authors present an interesting paper on the use of the interaction factor method (IFM) for settlement analysis of large pile groups. -
The distribution, type, popularity, size and availability of river-run gravel and crushed stone for use in land drainage systems, and their suitability for mineral soils in Ireland
(Compuscript for Teagasc (Agriculture and Food Development Authority, Ireland), 2022-06-24)The performance of land drainage systems installed in mineral soils in Ireland is highly variable, and is dependent on, amongst other factors, the quality and suitability of the aggregate used. In Ireland, aggregate for ... -
Dredged marine sediments stabilized/solidified with cement and GGBS: Factors affecting mechanical behaviour and leachability
(Elsevier, 2020-04-08)Management strategies for the safe disposal of contaminated dredged marine sediment are a global scale environmental issue. Stabilization/solidification method was investigated as a sustainable approach for the potential ... -
Driven cast-in-situ pile capacity: insights from dynamic and static load testing
(Canadian Science Publishing, 2021-02-11)Driven cast-in-situ (DCIS) piles are classified as large displacement piles. However, the use of an oversized driving shoe introduces additional complexities influencing shaft resistance mobilisation, over and above those ... -
Driven cast-in-situ piles in granular soil: applicability of CPT methods for pile capacity
(CBT'14, 2014)Most CPT-based design methods for driven piles are heavily influenced by research on preformed driven piles. In this paper, a critical review is made of the ability of these methods to predict the total capacity of driven ... -
Dynamics and function of intracellular carbohydrate in activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)Recovery of biodegradable plastics from activated sludge is a promising sustainable technology. In this study, polyhydroxybutyrate (PHB) ¿ a biodegradable plastics material - was produced by activated sludge performing ... -
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 ... -
Effect of chemical amendments to dairy soiled water and time between application and rainfall on phosphorus and sediment losses in runoff
(2012)Dairy soiled water (DSW) is a dilute, low nutrient effluent produced on Irish dairy farms through the regular washing down of milking parlours and holding areas. In Ireland, there is no closed period for the land application ... -
Effect of chemical amendments to dairy soiled water and time between application and rainfall on phosphorus and sediment losses in runoff
(Elsevier, 2012-05-18)Dairy soiled water (DSW) is a dilute, low nutrient effluent produced on Irish dairy farms through the regular washing down of milking parlours and holding areas. In Ireland, there is no closed period for the land application ... -
Effect of rainfall interval on runoff losses of biosolids and meat and bone meal when applied to a grassland soil
(Springer, 2014)This study assessed runoff losses following laboratory rainfall simulation on a grassland soil at two time intervals (48 and 216 h) after a single application of biosolids and meat and bone meal (MBM). The treatments were: ... -
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
(Elsevier, 2012)Manures need the addition of carbon-rich bulking agents to conserve N during composting, which increases the cost of the composting process. The recommended proportion of manure/sawdust, based on a carbon (C):nitrogen (N) ... -

The effect of thinning on mechanical properties of Douglas fir, Norway spruce, and Sitka spruce
(Springer Verlag, 2019-01-07)Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated. Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, ... -
The effect of wastewater treatment processes, in particular ultraviolet light treatment, on pathogenic virus removal: EPA Research Report 171
(Environmental Protection Agency, 2016-05)Format: pdf Download now Municipal wastewater treatment plant discharges are a recognised source of human pathogenic viruses. Of concern within this group is norovirus the leading cause of viral gastroenteritis ... -
The effects of array configuration on the hydro-environmental impacts of tidal turbines
(Elsevier, 2014-04)The economic viability of tidal turbines will require the deployment of multiple devices in array formations in a manner analogous to wind farms. This research investigates the effects of the configuration of a tidal turbine ... -
The effects of array configuration on the hydro-environmental impacts of tidal turbines.
(2012)Tidal stream turbines provide a technically viable means of generating electricity from a sustainable resource; however, economic viability will require the deployment of multiple devices in array formations in a manner ... -
Effects of complex hydrodynamic processes on the horizontal and vertical distribution of Tc-99 in the Irish Sea
(Elsevier ScienceDirect, 2010-10-14)The increased discharge of Tc-99 from the Sellafield plant following the commissioning of the Enhance Actinide Removal Plant in 1994 was reflected in higher Tc-99 activity concentrations over much of the Irish Sea The ... -
Effects of fertiliser on phosphorus pools in soils with contrasting organic matter content: A fractionation and path analysis study
(Elsevier, 2018-12-05)With the intensification of agricultural production in many European countries, more marginal soils with elevated organic matter (OM) content are being brought into cultivation. However, little is known about the transformations ...
