Video and laser based augmented reality stereoscopic viewing for mobile robot teleoperation
(IFAC Proceedings, 2010)This paper proposes an augmented reality visualization interface to simultaneously present visual and laser sensors information further enhanced by stereoscopic viewing. The use of augmented layers is proposed to represent ... -
An instrument for the simultaneous acquisition of size, shape, and spectral fluorescence data from single aerosol particles.
(SPIE (International Society for Optics and Phonotics), 2004)We describe the construction of a bio-aerosol monitor designed to capture and record intrinsic fluorescence spectra from individual aerosol particles carried in a sample airflow and to simultaneously capture data relating ... -
Real-time biological agent detection using particle size, shape and fluorescence characterisation
(SPIE (International Society for Optics and Phonotics), 2004)Developments in real time optical biological agent detection and sensing are presented which describe start of the art advances in the detection and warning of these pathogens. The following paper describes the basic ... -
A methodology for online wear debris morphology and composition analysis
(2008-11)Online or inline detection of basic debris features, i.e. size, quantity, size distribution, shape, and compositions simultaneously With real time diagnostics is one of the possible ways to perform Wear debris analysis ... -
Is erectile dysfunction a marker for cardiovascular disease?
(2001-11)There is now significant evidence that erectile dysfunction (ED) can be a symptom of cardiovascular disease, and can act as a marker for disease progression. National Health Service (NHS) prescribing restrictions on ... -
Incorporation of the acetylcholine receptor dimer from Torpedo californica in a peptide supported lipid membrane investigated by surface plasmon and fluorescence spectroscopy
(1998-09-15)The dimer species (M-r 580 000) of the nicotinic acetylcholine receptor, isolated from the electric organ of Torpedo californica, was incorporated into a thiopeptide supported lipid bilayer. The incorporation was achieved ... -
Electrostatic determinants of the ion channel control of the nicotinic acetylcholine receptor of Torpedo californica
(1998)The patch clamp K+-conductance G of the nicotinic acetylcholine receptor (AcChoR) dimer (M(r)approximate to 590 000) of Torpedo californica, reconstituted in lipid vesicles, icles, which decreases with increasing Cain the ... -
Psychological problems in New Zealand primary health care: a report on the pilot phase of the Mental Health and General Practice Investigation (MaGPIe)
(2001-01-26)Aim. To carry out a pilot study in two regions in order to investigate prevalence of psychological problems in primary care in New Zealand. Method. General Practitioners (GPs) within two geographic regions were randomly ... -
Methyl-group effect on the proton affinity of methylated acetophenons studied by two mass-spectrometric techniques
(1993-10)The proton affinities (PA) of all isomeric dimethylacetophenones were determined using the 'kinetic method' with a tandem mass spectrometer and by measurements of the proton transfer equilibrium in the gas phase by Fourier ... -
Mapping the energy surface of transmembrane helix-helix interactions
(2001-11)Transmembrane helices are no longer believed to be just hydrophobic segments that exist solely to anchor proteins to a lipid bilayer, but rather they appear to have the capacity to specify function and structure. Specific ... -
The structure of the HIV-1 Vpu ion channel: modelling and simulation studies
(2001-06-06)Vpu is an 81 amino acid auxiliary protein in HIV-1 which exhibits channel activity. We used two homo-pentameric bundles with the helical transmembrane segments derived from FTIR spectroscopy in combination with a global ... -
Use of a single glycine residue to determine the tilt and orientation of a transmembrane helix : A new structural label for infrared spectroscopy
(2000-12)Site-directed dichroism is an emerging technique for the determination of membrane protein structure. However, due to a number of factors, among which is the high natural abundance of C-13, the use of this technique has ... -
Structure of the Influenza C virus CM2 protein transmembrane domain obtained by site-specific infrared dichroism and global molecular dynamics searching
(2000-02-11)The 115-residue protein CM2 from Influenza C virus has been recently characterized as a tetrameric integral membrane glycoprotein. infrared spectroscopy and site-directed infrared dichroism were utilized here to determine ... -
Exploring models of the influenza A M2 channel: MD simulations in a phospholipid bilayer
(2000-01)The M2 protein of influenza A virus forms homotetrameric helix bundles, which function as proton-selective channels. The native form of the protein is 97 residues long, although peptides representing the transmembrane ... -
The economics of employing a counsellor in general practice : Analysis of data from a randomised controlled trial
(2000-04)Background. Counselling is currently adopted in many general practices, despite limited evidence of clinical and cost effectiveness. Aim. To compare direct and indirect costs of counsellors and general practitioners (GPs) ... -
Vpu transmembrane peptide structure obtained by site-specific Fourier transform infrared dichroism and global molecular dynamics searching
(1999-09)The recently developed method of site-directed Fourier transform infrared dichroism for obtaining orientational constraints of oriented polymers is applied here to the transmembrane domain of the vpu protein from the human ... -
Bio-aerosol fluorescence - Detecting and characterising bio-aerosols via UV light-induced fluorescence spectroscopy
