    Distribution of Acanthaster planci outbreaks on the Great Barrier Reef between 1966 and 1989 (1990)

    Notes: Abstract Analysis of data from 1966 to 1989 indicates 2 periods of abundant starfish outbreaks on the Great Barrier Reef (GBR). While the data for the first peak of activity (1966–1975) are relatively limited, the data for the most recent peak of activity (1981–1989) support the hypothesis of southward moving waves of outbreaks. The southward drift of outbreak activity is consistent with speed and direction of average summer currents on the GBR but the concept of a discrete seed area to initiate the wave is not substantiated, nor testable, with presently available data. As the present wave of outbreaks appears to be declining in the central section of the GBR (17–19°S) small residual populations may remain. If the outbreaks are coupled to coral recovery patterns then the next period of high starfish activity in the central section would be expected in the late-1990's.

    Preliminary observations of the decomposition of crown-of-thorns starfish, Acanthaster planci (L.) (1992)
    Springer

    Notes: Abstract The rate of decomposition of 67 crown-of-thorns starfish was monitored over 7–9 days on 2 reefs of the Great Barrier Reef in 7 permanent quadrats in different depths and habitats. The pattern of decomposition was similar in all quadrats irrespective of the site or depth. Many different organisms, including crown-of-thorns starfish, fed on or scavenged the remains. Despite this activity the remains could be recognised as crown-of-thorns starfish for up to 5 days. The reason for the sudden disappearance of starfish at the ends of outbreaks is briefly discussed.

    Plasma concentrations of bupivacaine after wound infiltration of an 0.5% solution after inguinal herniorrhaphy: a preliminary study (1993)
    Springer
    European journal of clinical pharmacology 44 (1993), S. 555-557

    Keywords: Bupivacaine ; wound infiltration ; postoperative ; pharmacokinetics

    Notes: Summary After routine inguinal herniorrhaphy we gave 12 patients a wound infiltration regimen of bolus doses of 20 ml of 0.5% bupivacaine via a catheter within the wound and rectally administered indomethacin (100 mg). Peak venous plasma bupivacaine concentrations ranged from 0.07 mg·l−1 to 1.14mg·l−1 (mean (SD) 0.47 (0.33) mg·l−1), and occurred at between 0.25 and 2 h after the first dose. Plasma concentrations were well below the toxic threshold of 4 mg·l−1 and there was no accumulation. The regimen provided satisfactory analgesia. There were no wound infections nor signs of toxicity.

    Estimates of the abundance of the crown-of-throns starfish Acanthaster planci in outbreaking and non-outbreaking populations on reefs within the Great Barrier Reef (1992)
    Springer
    Marine biology 113 (1992), S. 509-515 
    Details
    ISSN: 1432-1793

    Topics: Biology
    Notes: Abstract Criteria used to define outbreaking and non-outbreaking populations of Acanthaster planci are described. Estimates of starfish density were derived for these population types from a series of intensive underwater surveys and from calibrated manta-tow surveys of 334 reefs within the Great Barrier Reef, from January to October 1987. By comparison of these data, density differences were identified between the two populations. Both the mean density and total numbers of non-cryptic crown-of-thorns starfish in outbreaking populations are at least one order of magnitude greater than that in non-outbreaking populations. Non-outbreaking populations may comprise up to 1500 starfish km-2, an order of magnitude less than some previous estimates for reefs within the Great Barrier Reef. Densities of ≳1500 starfish km-2 indicate that an individual reef may be experiencing an outbreak. This density is equivalent to an average of 0.22 starfish per 2 min manta tow over the whole reef. Approximately 90% of reefs classified as out-breaking on the Great Barrier Reef had densities of 〉1500 starfish km-2, while about 96.5% of reefs classified as non-outbreaking had densities below this level.

    Studies in individual spawnings of Salmo salar: a model to explain chromosome polymorphism patterns (1992)
    Springer

    ISSN: 1432-2242

    Notes: Summary Atlantic salmon fry from nine offspring belonging to individual spawnings were karyotyped. Different patterns of Robertsonian chromosome polymorphism were obtained. A theoretical model is developed to explain the different chromosome polymorphism patterns in Salmo salar offspring in terms of the chromosome numbers of the parents.

    A new MRI formulation for flow and motion applications (1994)
    Springer
    Magnetic resonance materials in physics, biology and medicine 2 (1994), S. 185-189 
    Details
    ISSN: 1352-8661
    Keywords: flow-imaging ; MR motion artifacts ; MR phase shifts
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine , Physics
    Notes: Abstract A rigorous reformulation of the magnetic resonance (MR) image formulation model (IFM) can use the integrally cumulative nature of MRI phase shifts for encoding and of time-of-flight travel corrections for magnitude. This approach characterizes each independent gradient element by its cumulant waveforms,K N (t), instead of by particular time expansion in gradient moments. The lowest-order cumulant gradient that gives a simple monopolar waveform governs all resulting phase-encoding properties. Each gradient element specifically encodes one and only one motion-order variable. Phase sensitizations to “higher order” do not exist; they are mathematical psuedophasings. Magnetization isochromats may have arbitrarily complicated velocity history,V(t), appearing in both time-of-flight and motion phase-shift formulas. The subject's intravoxel motion subdistributions each automatically reference the correct mean time of encoding action and its encoding duration. This formulation yields very simple and generalizable IFM expressions for MRI acquired data, with no theoretical confusion regarding higher-order phase shifts and nonphased time-of-flight effects.

    Effects of SO2 deposition on painted steel surfaces (1990)

    Notes: The effects of 1 ppm SO2 with high humidity on alkyd-painted steel was investigated using x-ray photoelectron spectroscopy (XPS) and adhesion tensile tests. The SO2 caused a spotted discoloration on the specimens on which dew is allowed to dry and accelerated the loss of adhesion between the primer and the steel. The brown spots are characterized by a high S content and form in areas where the condensed dew becomes more concentrated in H2SO3 or H2SO4 as it evaporates. Specimens not exposed to dew also have high S concentration on the surface, but do not discolor. High humidity alone caused a loss of adhesion at the primer-metal interface, but SO2 increased the rate of this de-adhesion. Such a loss of adhesion decreases the protection provided by the paint system and the presence of Fe on both sides of some failures indicated that the substrate was beginning to corrode.
