Factors influencing 4-fluorobenzoate degradation in biofilm cultures of Pseudomonas knackmussii B13 (Elsevier, 2011-05)Membrane aerated biofilm reactors (MABRs) have potential in wastewater treatment as they permit simultaneous COD minimisation, nitrification and denitrification. Here we report on the application of the MABR to the removal ...

(Optical Society of America, 2010-01-01)The linear canonical transform provides a mathematical model of paraxial propagation though quadratic phase systems. We review the literature on numerical approximation of this transform, including discretization, sampling, ...
-
(Optical Society of America, 2005-05-01)The linear canonical transform (LCT) describes the effect of any quadratic phase system (QPS) on an input optical wave field. Special cases of the LCT include the fractional Fourier transform (FRT), the Fourier transform ...
-
(Taylor & Francis, 2011-04)Ireland's water treatment residual (WTR) production rate and reuse situation was investigated to complement the novel research on WTR reuse development in University College Dublin, Ireland. The resulting GIS maps reveal ...
-
(2006-02)This paper presents the results of an investigation into the fatigue performance of a 20mm Binder Course Asphalt Pavement Mix incorporating Recycled Asphalt Pavement (RAP). For the study, a series of binder course mixes ...
-
(Taylor & Francis, 2010-11)Currently, organic polymers are adopted in alum sludge (aluminium-coagulated drinking water treatment sludge) conditioning. However, there are important concerns regarding the use of these polymers because of the unknown ...
-
(Institution of Civil Engineers, 2010-02-01)This paper presents the results of a series of field tests performed to study the effect of soil plugging during installation on the base resistance developed by an open-ended (pipe) pile in clay. Three instrumented pipe ...
-
(NRC Research Press, 2010-07)This paper presents the results of a series of field experiments performed to study the effect of installation method on the shaft resistance developed by a pile installed in soft clayey silt. Tests were performed on piles ...
-
(Institution of Civil Engineers/Thomas Telford Publishing, 2009-10)This paper presents the results from an experimental programme that studied the factors affecting the bearing resistance of shallow footings in sand. In particular, the tests considered the effects of the footing width and ...
-
(Taylor & Francis (Routledge), 2010-07-11)In Bridge Weigh-in-Motion (B-WIM), an instrumented bridge is used as a scales to weigh passing trucks and their axles. The most common algorithm upon which modern B-WIM systems are based remains that developed by Moses ...
-
(ASRANet Ltd, 2006-07)To assess the safety of an existing bridge, the loads to which it may be subject in its lifetime are required. Statistical analysis is used to extrapolate a sample of load effect values from the simulation period to ...
-
(BCRI, 2010)This paper presents the potential of the cross-entropy method to surmise the properties of a simply supported beam using as input the response of the structure to a moving load. The beam model is discretised into a number ...
-
(Wiley, 2010-08-23)The energetic and electronic structures of V-doped anatase TiO2 have been investigated systematically by the GGA+U approach, including replacement of Ti by V in the absence and presence of oxygen vacancies and the presence ...
-
(American Institute of Physics, 2009-04-02)The electronic properties and photocatalytic activity of nitrogen (N) and/or tungsten (W)-doped anatase are calculated using density functional theory. For N-doping, isolated N 2p states above the top of the valence band ...
-
(ACS Publications, 2009-09-15)The structural, energetic and electronic properties of various S doping configurations by substitution and adsorption at the rutile TiO2 (110) surface have been investigated by first-principles density functional theory ...
-
(RSC publishing, 2011-06-23)Using Time-Dependent Density Functional Theory (TD-DFT), we have investigated the optical properties of dye-sensitized solar cells (DSSCs) comprised of TiO2 nanoparticle sensitized with two coumarins, namely, NKX-2311 and ...
-
(Springer, 2010-11-13)This paper reports on an Irish study examining first year students’ recollections of their concerns, motivations, level of preparedness and perceived skills on entry to university. The study aims to investigate and understand ...
-
(American Society of Civil Engineering (ASCE), 2009-11)Aerial Light Detection and Ranging (LiDAR) offers the potential to auto-generate detailed, three-dimensional (3D) models of the built environment in urban settings. Auto-generation is needed as manual generation is not ...
-
(Taylor and Francis, 2004)Conventional resistance equations (such as those of Manning, Chézy and Darcy-Weisbach) are inappropriate for flow through emergent vegetation, where resistance is exerted primarily by stem drag throughout the flow depth ...
-
(Inderscience, 2008-04)As a biomass material, bone char was investigated for the feasibility to be used as a cost-effective biosorbent for fluoride removal from drinking water in groundwater environment. Based on the batch tests with natural ...
