    Phosphorus cycling in a dense Potamogeton pectinatus L. Bed (1981)

    Notes: Summary An analysis of phosphorus concentrations and standing stocks in the various components of a dense Potamogeton pectinatus L. community in a brackish lake showed that the amounts of P per unit area varied in the following order: Sediments 〉 Above ground macrophytes 〉 Detritus 〉 Benthic Invertebrates 〉 Below ground macrophyte tissue 〉 Epiphytic algae 〉 Water soluble P 〉 Water borne particulate P. Seasonal changes in the variability of these stocks are described, and shown to be controlled by the annual growth and decomposition pattern of the Potamogeton. The sediments were suggested as the major source of P for the plant biomass. Studies using 32P tracer showed that of a given input of P to the water, 32% went to large epiphytic algae, 17% to the Potamogeton, 16% to the benthic fauna (mostly filter feeding bivalves), 28% to the sediments (almost all incorporated in the top 1 cm), and the remaining 7% was adsorbed on to, or absorbed by microorganisms associated with detritus. Analysis of 32P uptake curves indicated that of the P absorbed by the Potamogeton, a significant proportion went to the complex adnate periphyton on the leaf surface. We were unable to separate this fraction. Movement of P in the community was shown to be a closed cycle, and any release of P from decaying macrophytes would be rapidly reabsorbed by epiphytic algae. It is unlikely that phosphorus, once cycling in the macrophyte community, would become transferred to the circulation in the open lake.

    A detailed survey near Mount Eratosthenes Eastern Mediterranean (1984)

    Notes: Abstract A detailed marine survey made to the South West of Mount Eratosthenes is described. The results show the existence of a narrow zone of WNW trending deformed sediment west of the mount surrounded by an evaporite sequence in different stages of deformation. This work was intended to settle the conflict between the results of three previous interpretations of the tectonic structure of this area. We see the area being characterised by five areas with different degrees of tectonic deformation yet showing little causal relationship to overburden of Nile Cone sediments. A fault controlled cliff coincides with the previously described salt wall and strike slip fault yet we see no evidence for its diapiric origin nor positive evidence for strike slip motion along it. We concur with the previously observed area of higher free-air gravity anomalies termed the Eratosthenes tectonic zone, although it is traversed by several boundaries between areas of different deformation. Our results thus show some agreements and some re-interpretations of the observations. This complicated region is not yet fully understood however.

    The western intersection of Oceanographer fracture zone with the mid-Atlantic ridge (1984)
    Springer
    Marine geophysical researches 6 (1984), S. 143-158

    Notes: Abstract A survey across the western intersection of the mid-Atlantic ridge with Oceanographer fracture zone near 35°N shows this intersection to be different in character from its more typical eastern counterpart. At the western junction the transform valley broadens into a parallelogram shaped deep some 46 by 24 km, which extends well across the trace of the active transform. Within 30 km south of the fracture zone the median valley becomes oblique forming a NE trending ridge which is the SE edge of the deep. Magnetic mapping shows the current spreading centre to be adjacent to this ridge. A sequence of evolution for this intersection over the past 0.7 Ma is proposed to explain the features mapped. We suggest that the oblique ridge crest trends extended across the transform trace to form the elongated graben-like deep with its associated faults and sediment slumps. Such complex patterns may occur as plate-wide changes in spreading direction become modified by localised shear stress fields at ridge crest-transform intersections, as have been observed in a number of other cases. The absence of significant tranverse ridges across from the spreading centre at this particular fracture zone intersection, may have temporarily allowed these stress patterns to propagate across the fracture zone.

    Notes: Summary We compared a simple complement-dependent lymphocytotoxicity test with a widely used indirect immunofluorescence procedure to enumerate total T, T helper, and T suppressor lymphocytes in normal blood samples. Results with the two techniques were closely similar.

    Cadmium in the atmosphere (1984)
    Springer
    Cellular and molecular life sciences 40 (1984), S. 29-36

    Notes: Summary Cadmium is present naturally in the air mainly as a result of volcanic emissions and release by vegetation. Anthropogenic sources, which overall give rise to emissions one order of magnitude greater than natural sources, are largely primary non-ferrous metals production and waste incineration. Measured concentrations of airborne cadmium are typically 〈 1 ng m−3 at remote sites, 0.1–10 ng m−3 at rural sites and 1–100 ng m−3 at urban and industrial sites, dependent upon the nature and proximity of local sources. Particle sizes are generally 〈2 μm, and often considerably smaller, consistent with an anthropogenic source and a long atmospheric life-time. Cadmium deposition to the land occurs with fluxes varying from 0.05 ng cm−2 month−1 in Greenland to circa 1000 ng cm−2 month−1 in the vicinity of major industrial sources. The possible significance of a motor vehicular source of airborne cadmium is also reviewed.

    The localised distribution of U and other incompatible elements in spilitic pillow lavas (1981)
    Springer
    Contributions to mineralogy and petrology 78 (1981), S. 111-117

    Notes: Abstract The fission track technique was used not only to determine the U distribution, but indirectly, to locate the host minerals of other incompatible elements such as P, Ti, Y, Zr and Nb in spilitic pillow lavas from SW England. The majority of U was introduced early in the alteration process probably due to interaction with sea-water. At a later stage in the process, these elements, some previously considered to be relatively immobile during low-grade alteration, were mobilised and subsequently redeposited in stable secondary phases. The hydrothermal fluid responsible for mobility was rich in CO2 and H2O. Carbonate complexes were the most likely mobile species.

    Severe penicillin-induced cholestasis in a 91-year-old woman (1981)

    Notes: Summary An elderly woman was admitted for treatment of severe stasis ulceration, associated with varicose veins. One course of cloxacillin was given orally followed by a second course of penicillin-G to eradicate persistant hemolytic streptococcal skin infection. Deep progressive jaundice subsequently developed due to intrahepatic cholestasis and persisted for several weeks before resolution. Having excluded a progressive extrahepatic malignant lesion by appropriate investigations, the diagnosis was substantiated by classical changes present in a percutaneous liver biopsy.
