  1. Extreme significant wave height climate in the Gulf of Guinea

    Extreme significant wave height climate in the Gulf of Guinea

    Item type: Journal Article • Journal: African Journal of Marine Science
    This article investigates spatio-temporal trends for different return periods of extreme significant wave height (SWH) in the Gulf of Guinea (GG), northeastern tropical Atlantic Ocean, based on a 37-year (1980–2016) wave hindcast. High-resolution reanalysis windfield datasets were used to force...
  2. Approximate Symmetries of the Boussinesq Equation

    Approximate Symmetries of the Boussinesq Equation

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper we show that all exact symmetries of the linear wave equation are inherited by the Boussinesq type equation with a small parameter as approximate symmetries in any order of precision. We find an approximate integraldifferential transformation of...
  3. A Complete Symmetry Classification and Reduction of Some Classes of the Nonlinear (1-2) Wave Equation

    A Complete Symmetry Classification and Reduction of Some Classes of the Nonlinear (1-2) Wave Equation

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A classification of symmetries of a nonlinear one-two wave equation is given with their respective commutator tables. Two dimensional Lie algebras of point symmetry generators are used to construct exact solutions for some classes invariant under the subalgebra. Comparisons and...
  4. HIV/AIDS, childhood and governance: sundering the bonds of human society

    HIV/AIDS, childhood and governance: sundering the bonds of human society

    Item type: Journal Article • Journal: African Journal of AIDS Research
    There is a disharmonious resonance between the length of HIV infection in the individual human host and the length of a human generation. In brief, an infected person may have children, these may be orphaned and grow up to become...
  5. Juvenile fish recruitment through wave-overtopping into a closed subtropical estuary

    Juvenile fish recruitment through wave-overtopping into a closed subtropical estuary

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The fish fauna of the subtropical Nhlabane estuary in northern KwaZulu-Natal was studied during a regional drought over the period 1991–1995. The estuary mouth closed in late 1991, due to the drought and to water abstraction from the system, and...
  6. Spatial Comparisons of Populations of an Indigenous Limpet <em>Scutellastra Argenvillei</em> and an Alien Mussel <em>Mytilus Galloprovincialis</em> Along a Gradient of Wave Energy

    Spatial Comparisons of Populations of an Indigenous Limpet <em>Scutellastra Argenvillei</em> and an Alien Mussel <em>Mytilus Galloprovincialis</em> Along a Gradient of Wave Energy

    Item type: Journal Article • Journal: African Journal of Marine Science
    In the 1970s, the Mediterranean mussel Mytilus galloprovincialis invaded the South African coast and spread rapidly to dominate much of the West Coast, indicating either the opportunity to occupy a vacant niche or its superior competitive capability over indigenous species...
  7. Temporal Changes in an Interaction Between an Indigenous Limpet<em>Scutellastra Argenvillei</em> and an Alien Mussel <em>Mytilus Galloprovincialis</em>: Effects of Wave Exposure

    Temporal Changes in an Interaction Between an Indigenous Limpet<em>Scutellastra Argenvillei</em> and an Alien Mussel <em>Mytilus Galloprovincialis</em>: Effects of Wave Exposure

    Item type: Journal Article • Journal: African Journal of Marine Science
    A previous survey of 15 sites off the Namaqualand coast on the west coast of South Africa provided evidence of a competitive interaction between an alien mussel Mytilus galloprovincialis and an indigenous limpet Scutellastra argenvillei, and indicated that wave action...
  8. The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa

    The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Analysis of sea-level data obtained from the Atlantic Global Sea Level Observing System (GLOSS) sea-level station at Takoradi, Ghana, West Africa, clearly reveals a tsunami signal associated with the Mw = 9.3 Sumatra earthquake of 26 December 2004 in the...
  9. The flexural properties of young <em>Pinus elliottii</em> x <em>Pinus caribaea</em> var. <em>hondurensis</em> timber from the Southern Cape and their prediction from acoustic measurements

    The flexural properties of young <em>Pinus elliottii</em> x <em>Pinus caribaea</em> var. <em>hondurensis</em> timber from the Southern Cape and their prediction from acoustic measurements

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The objectives of this study were to determine the bending strength and stiffness properties of young Pinus elliottii x P. caribaea var. hondurensis timber from the Southern Cape, South Africa, and to evaluate the predictability of these properties from acoustic...
  10. Why <em>Carcinus maenas</em> cannot get a grip on South Africa's wave-exposed coastline

    Why <em>Carcinus maenas</em> cannot get a grip on South Africa's wave-exposed coastline

    Item type: Journal Article • Journal: African Journal of Marine Science
    The European green crab Carcinus maenas has established considerable breeding populations in harbours and sheltered bays in the South-Western Cape, South Africa, but appears unable to flourish on the wave-exposed coastline. This study compares the abilities of C. maenas and...
