Diagnostic definitions and figures of male and female Tetanocera punctifrons and T. latifibula, new records of T. punctifrons in Ireland, and notes on biology (Diptera, Sciomyzidae).
(The Society for the study of flies (Diptera) affiliated to the British Entomological and Natural History Society (BENHS), 2017)The presence of Tetanocera punctifrons Rondani, 1868 in Ireland is reconfirmed. The species is distinguished from the very similar T. latifibula Frey, 1924. The female abdomens of both species are described for the first ... -
Diagnostics and intervention methods for façade retrofit of post-WWII non-domestic buildings in Europe for energy efficiency
(NUI Galway, 2016-08-29)The growing demand of deep façade retrofits in refurbishment projects across Europe, is often accompanied by low-energy targets and architectural attributes. Factors like variability in context, material, environment and ... -
Different depth sand filters for laboratory treatment of synthetic wastewater with concentrations close to measured septic tank effluent
(2011)The objective of this study was to apply hydraulic and chemical oxygen demand (COD) loading rates at the upper limits of the design criteria for buried sand filters to test the sand filter depth design criteria. Over a ... -
The dilemma of opportunity in developing a life cycle assessment of emerging aquaculture systems - a case study of a Eurasian perch (Perca fluviatilis) hatchery recirculating aquaculture system

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) ... -
