Legal Risk Management, Governance and Compliance : A Guide to Best Practice from Leading Experts
(Globe Law and Business, 2013-05)While identifying risks and regulatory challenges, chapters also explore how professionals can manage processes; implement change; track issues and loss events; screen potential clients, partners, employees and contractors; ... -
Effectiveness of the use of simulation training in healthcare education
(University of Hertfordshire, 2013-02)The focus of the research programme within this thesis is an investigation of scenario-based simulation training in undergraduate healthcare education. The aim of the main study was to determine the effectiveness of ... -
The effect of pre-straining on the mechanical behaviour of self-piercing riveted aluminium alloy sheets
(2006)Self-piercing riveting as an alternative joining method to spot-welding has attracted considerable interest from the automotive industry and has been widely used in aluminium intensive vehicles. Pressing and stamping are ... -
Micro throttle pump employing displacement amplification in an elastomeric substrate
(2005-10)We report a micro throttle pump (MTP) with enhanced throttling resulting from beneficial deformation of its elastomer substrate. In the MTP reported, this has doubled the effective deflection of the piezo electric (PZT) ... -
Continuously variable mixing-ratio micromixer with elastomer valves
(2005-10)We report a self-contained microfluidic alternate flow injection mixer (AFIM) employing piezoelectrically actuated, PDMS seal-valves to control injection. AFIMs employ pulsatile injection of liquids to enhance interface ... -
Dual independent displacement-amplified micropumps with a single actuator
(2006-08)We report a dual-micropump structure operated by a single actuator element. The constituent micropumps are a form of micro throttle pump (MTP) comprising a narrow flow channel incorporating two microthrottles. We term this ... -
Microfluidic solid phase suspension transport with an elastomer-based, single piezo-actuator, micro throttle pump
(2005)We report a Micro Throttle Pump (MTP) which has been shown to pump 5 mm diameter polystyrene beads at a concentration of 4.5 x 10(7) beads ml(-1). This new MTP design is constructed in a straightforward manner and actuated ... -
Polymyxa graminis and the cereal viruses it transmits : a research challenge
(2003-09)Polymyxa graminis is a eukaryotic obligate biotrophic parasite of plant roots that belongs to a poorly studied discrete taxonomic unit informally called the 'plasmodiophorids'. P. graminis is nonpathogenic, but has the ... -
Effects of temperature on maturation of pseudothecia of Leptosphaeria maculans and L-biglobosa on oilseed rape stem debris
(2003-12)Effects of temperature on maturation of pseudothecia of Leptosphaeria maculans and L. biglobosa, closely related species which coexist on UK oilseed rape, were investigated. Stages in pseudothecial maturation on naturally ... -
Fitness cost associated with loss of the AvrLm4 avirulence function in Leptosphaeria maculans (Phoma stem canker of oilseed rape)
(2006-01)Near-isogenic isolates of Leptosphaeria maculans differing at the AvrLm4 avirulence locus (AvrLm4 or avrLm4) were produced in vitro. Methods for inoculation of leaves of oilseed rape with ascospores or conidia were compared. ... -
3,4-methylenedioxymethamphetamine (ecstasy) inhibits dyskinesia expression and normalizes motor activity in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-treated primates
(2003-10-08)Ecstasy [3,4-methylenedioxymethamphetamine (MDMA)] was shown to prolong the action of L-3,4-dihydroxyphenylalanine (L-DOPA) while suppressing dyskinesia in a single patient with Parkinson's disease (PD). The clinical basis ... -
Clinical manifestations of VX poisoning following percutaneous exposure in the domestic white pig
(2003-05)Nerve agents are a class of organophosphorus chemicals that inhibit certain cholinesterase enzymes (ChE). If untreated, percutaneous exposure to nerve agents, such as VX (O-ethyl-S-[2(diisopropylamino)ethyl] methylphosph ... -
Unstable Bessel beam resonator
(2003-08-01)We examine the properties of a Bessel–Gauss resonator design studied previously, and explain the bell-shaped modulation imposed on its lowest-order mode in terms of an equivalent linear cavity. We propose an unstable cavity ... -
Correlated pair excitations in Bose Einstein condensates in the presence of a Raman coupling
(2003-04-01)We show that it is possible to determine the existence of correlated pairs produced in a down-conversion process within an atomic Bose–Einstein condensate in a systematic manner. This is achieved by measuring the competition ... -
Interactions between bacteria and plant-parasitic nematodes : now and then
(2003-09-30)Based on genome-to-genome analyses of gene sequences obtained from plant-parasitic, root-knot nematodes (Meloidogyne spp.), it seems likely that certain genes have been derived from bacteria by horizontal gene transfer. ... -
A sensitive DNA-probe for the detection of polymyxa-betae in sugar-beets roots
(1993-11)A Polymyxa betae genomic DNA fragment of 1·9 kb has been cloned from infected sugar beet roots and shown to contain DNA sequences that are repeated on at least four different chromosomes. A probe generated from this fragment ... -
Evaluation of a barrier cream against the chemical warfare agent VX using the domestic white pig
(2005-07)The purpose of this study was to evaluate the efficacy of a novel barrier cream formulation at reducing the percutaneous toxicity of a 2xLD(50) liquid challenge of nerve agent (VX). The study was conducted in vitro and in ... -
In vivo skin absorption and distribution of the nerve agent VX (O-ethyl-S-[2(diisopropylamino)ethyl] methylphosphonothioate) in the domestic white pig
(2005-07)The purpose of this study was to characterize the skin absorption and distribution of VX (O-ethyl-S-[2 (diisopropylamino)ethyl] methylphosphonothioate) in the domestic pig in order to evaluate the animal as a potential ... -
Financialized accounts : A stakeholder account of cash distribution in the S&P 500 1990-2005
(2007)In this paper, we construct a financialized account of corporate restructuring in S&P 500 survivor firms where corporate transactions are accounted for at fair value or are marked to market. Accounting practitioners are ...
