Use of a fluorescent viability stain to assess lethal and sublethal injury in food-borne bacteria exposed to high-intensity pulsed electric fields. (2004).
(The Society for Applied Microbiology, 2004-07)
Aims: To apply scanning electron microscopy, image analysis and a fluorescent viability stain to assess lethal and
sublethal in food-borne bacteria exposed to high-intensity pulsed electric fields (PEF).
Methods and ...
Investigation of critical inter-related factors affecting the efficacy of pulsed light for inactivating clinically relevant bacterial pathogens
(Wiley, 2009-08)
Aims: To investigate critical electrical and biological factors governing the efficacy of pulsed light (PL) for the in vitro inactivation of bacteria isolated from the clinical environment. Development of this alternative ...
Transient response simulation of a composite material footbridge to crossing pedestrians.
(CRC Press, 2003)
Loads applied by pedestrians, and crowds of pedestrians, are particularly important for footbridges with natural frequencies close to footfall frequencies of moving pedestrians. Recorded response data from Aberfeldy Bridge, ...
Pulsed-plasma gas-discharge inactivation of microbial pathogens in chilled poultry wash water.
(International Association for Food Protection, 2007-12)
A pulsed-plasma gas-discharge (PPGD) system was developed for the novel decontamination of chilled poultry washwater. Treatment of poultry wash water in the plasma generation chamber for up to 24 s at 4C reduced Escherichia ...
Studies on the inactivation of medically important Candida species on agar surfaces using pulsed light.
(2009-07)
Development of a pulsed-light (PL) approach to inanimate surface decontamination
is timely, as the incidence of yeast-related infections in healthcare remains
unacceptably high. Critical electrical and biological factors ...
Investigation of a novel freeze-thaw process for the production of drug delivery hydrogels
(Springer, 2005-12)
Poly(vinyl alcohol) (PVA) is a water-soluble, biocompatible and biodegradable polymer, which has been widely applied in biomedical fields. In this paper, novel physically cross-linked hydrogels composed of PVA and comprising ...
Accelerated solvent based extraction and enrichment of selected plasticisers and 4-nonylphenol, and extraction of tin from organotin sources in sediments, sludges and leachate soils.
(Elsevier, 2009-02-23)
Enrichment techniques have become an important feature in the trace analysis of oestrogen mimicking chemicals in the environment. Recent developments such as accelerated solvent extraction (ASE) have improved extraction ...
Vertical crowd load models for vibration serviceability assessment of footbridges
(Civil-Comp Press, 2009)
Most pedestrian load models prescribed in existing design codes of practice do not
consider any interaction between the pedestrian and the moving structure. However,
it is now widely accepted that this interaction is ...
An investigation into possible sources of phthalate contamination in the environmental analytical laboratory.
(Taylor & Francis Online, 2007-02)
A study of common laboratory equipment and components was performed in order to identify sources of contamination of phthalates prior to testing environmental samples for such compounds. A screening study revealed significant ...
Synthesis and characterisation of novel n-vinyl pyrrolidinone/acrylic acid copolymers for use in biomedical applications.
(2006)
The aim of this study was to develop a novel hydrophilic polymer for use in biomedical applications. The polymers synthesised in this work were based on the monomers N-vinyl pyrrolidinone (NVP) and acrylic acid (AA) and ...
