Behaviour of tubular steel members under cyclic axial loading
(2006)This paper examines the cyclic performance of axially-loaded tubular members used as bracing elements to provide lateral seismic resistance in steel framed structures. An experimental study into the response of members ... -
Biaxial loading of offshore monopiles: numerical modelling
(American Society of Civil Engineers, 2016-05-18)In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ... -
Bioaccumulation of metals in ryegrass (Lolium perenne L.) following the application of lime stabilised, thermally dried and anaerobically digested sewage sludge.
(Elsevier ScienceDirect, 2016-05-09)The uptake and accumulation of metals in plants is a potential pathway for the transfer of environmental contaminants in the food chain, and poses potential health and environmental risks. In light of increased population ... -
Building performance optimization using cross-domain scenario modeling, linked data, and complex event processing
(Elsevier, 2013-01-28)The scenario modeling method empowers building managers by enabling comprehensive performance analysis in commercial buildings, but is currently limited to data from the building management domain. This paper proposes that ... -
Calibrated CFD simulation to evaluate thermal comfort in a highly-glazed naturally ventilated room
(Elsevier, 2013-08-30)Natural ventilation is a sustainable solution to maintaining healthy and comfortable environmental conditions in buildings. However, the effective design, construction and operation of naturally ventilated buildings require ... -
Carbon and nitrogen dynamics and greenhouse gas emissions in constructed wetlands treating wastewaters: a review
(2016-02-17)The removal efficiency of carbon (C) and nitrogen (N) in constructed wetlands (CWs) is very inconsistent and frequently does not reveal whether the removal processes are due to physical attenuation or whether the different ... -
Carbon costs and savings of Greenways: creating a balance sheet for the sustainable design and construction of cycling routes
(Inderscience, 2013-09-10)A modal shift to cycling has the potential to reduce carbon emissions in the transport sector. However, the carbon footprint of constructing new cycling routes, particularly greenways, has not been previously considered ... -
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ... -
Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
(Taylor & Francis, 2018-06-05)Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental ... -
Changing energy cultures? Household energy use before and after a building energy efficiency retrofit
(Elsevier, 2019-12-03)Government- and community-initiated energy retrofits of existing residential buildings abound across Europe. This paper argues that retrofitting initiatives need to extend their current emphasis on technical-material changes ... -
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 ... -
Chemical amendment of pig slurry: control of runoff related risks due to episodic rainfall events up to 48 hours after application.
(2013)Losses of phosphorus (P) from soil and slurry during episodic rainfall events can contribute to eutrophication of surface water. However, chemical amendments have the potential to decrease P and suspended solids (SS) losses ... -
Comparison of a stratified and a single-layer laboratory sand filter to treat dairy soiled water from a farm-scale woodchip filter
(Springer, 2014-04)Washing-down parlours and standing areas, following milking on dairy farms, produces dairy soiled water (DSW) that contains variable concentrations of nutrients. Aerobic woodchip filters can remove organic matter, nutrients ... -
A computational toolchain for the automatic generation of multiple Reduced-Order Models from CFD simulations
(Elsevier, 2019-05-25)This paper describes the development of a systematic tool chain capable of automatically extracting accurate and efficient Reduced-Order Models (ROMs) from Computational Fluid Dynamics (CFD) simulations. These ROMs can ... -
Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates.
(Elsevier, 2014-10-13)The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. ... -
Constructed wetlands for the treatment of highway runoff.
(Nova Publishers, 2008-06-01)Highway surface runoff contains pollutants such as total suspended solids (TSS), hydrocarbons, de-icing salts, and heavy metals. Treatment methods for highway runoff include storage/treatment facilities, such as constructed ... -
Contrasting yield responses to phosphorus applications on mineral and organic soils from extensively managed grasslands: Implications for P management in high ecological status catchments
(Wiley, 2018-09-13)Phosphorus (P) loss from grassland production is one of the main causes affecting high status water bodies in Europe. Soils with a high content in organic matter (OM), even if extensively managed, are particularly vulnerable ... -
