    Notes: Abstract The concentrations of selected metabolites in the posterior temporoparietal cortex of 13 Alzheimer's diseased (AD) and four nondemented postmortem brains (of individuals between the ages of 63 and 95) were determined using high-resolution 1H nuclear magnetic resonance (NMR) spectroscopy. The estimates for glutamate and inositol for AD brains did not show any statistically significant difference (P〉0.05) from those for the nondemented brains. The putative neuronal marker N-acetyl aspartate (NAA), creatine, and GABA were decreased in AD brains compared with the nondemented brains. The estimates for creatine, glutamate, and GABA showed significant linear correlations with those of NAA. Creatine, glutamate, GABA, and NAA appeared to be negatively correlated with the neurofibrillary tangles. Our results support a neuronal loss in the posterior temporoparietal cortices of AD brains.

    Experimental evaluation of bacterial barrier properties of ‘Hydron’ films (1983)
    Springer
    European journal of plastic surgery 7 (1983), S. 141-145

    Notes: Summary ‘Hydron’ is a new synthetic environmental barrier made directly on the wound surface by alternately spraying polyethylene glycel-400, which is a liquid, and polyhydroxymethyle methacrylate powder. Different thicknesses of ‘Hydron’ film were tested as barriers to bacterial penetration while still allowing evaporation from the wound and permitting antibiotics applied to the surface of the film to pass through to the wound. Six test strains of known sensitivity were used, three of Staphylococcus aureus and three of Pseudomonas pyocyaneus. The study proved convincingly that the thicker type II and type III films were impermeable to bacteria but allowed evaporation and permitted antibiotics applied to the surface to get through it to the wound. Type I film, using only two layers of fluid and one layer of powder is ineffective as a barrier to bacteria.

    Ultraviolet bands of Na2 and K2 (1991)
    Springer
    The European physical journal 18 (1991), S. 379-382

    ISSN: 1434-6079

    Topics: Physics
    Notes: Abstract The ultraviolet spectra of Na2 and K2 molecules have been investigated. These studies were made in absorption in the second order of a 3.4 m Ebert Spectrograph with a reciprocal dispersion of 2.6 Å/mm. A number of new bands in the spectra of both the molecules not previously reported have been observed. Computer methods have been used to calculate the term values and to evaluate molecular constants.

    Parallel three-dimensional finite difference beam propagation methods (1995)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: In this work, we show the implementation of two explicit three-dimensional finite-difference beam propagation methods (BPM) on two different parallel computers, namely a transputer array and a Connection Machine (CM). To assess the performance of using parallel computers, serial computer codes of the two methods have ben implemented and a comparison between the speed of the serial and paralledl codes has been made. Large gains in the speed of the paralled FD-BPMs has been obtained compared to the serial implementations. In addition, a comparison between the performance of the transputer array and the CM in executing the two FD-BPMs has been discussed. Finally, to assess and compare the two methods, three different rib waveguides and three different directional couplers have been analysed and the results compared with published results.
