  1. Outcomes 30 days after ICU admission: the 30DOS study

    Outcomes 30 days after ICU admission: the 30DOS study

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: The spectrum of illness and long-term outcome of critically ill patients admitted to intensive care units (ICUs) in South Africa remains largely unknown.
  2. ULTRA-UNIVERSAL MODELS

    ULTRA-UNIVERSAL MODELS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The concept of ultra-universal algebras in varieties is generalized to models of first order theories. Characterizations of theories which have ulta-universal models are found and general examples of ultra-universal models are investigated. In particular we show that a theory has...
  3. COUNTABILITY PROPERTIES IN INTERIOR ALGEBRAS

    COUNTABILITY PROPERTIES IN INTERIOR ALGEBRAS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Certain topological countability properties are generalized to interior algebras and basic reaults concerning these properies are investigated. The preservation of these properties under the formation of principal quotients and under a new construction called a join of interior algebras, is...
  4. Productivity of dinoflagellate blooms on the west coast of South Africa, as measured by natural fluorescence

    Productivity of dinoflagellate blooms on the west coast of South Africa, as measured by natural fluorescence

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The biomass and productivity of phytoplankton populations inshore on the west coast of South Africa were investigated towards the end of the upwelling season, a period when high-biomass dinoflagellate blooms are common. Productivity was estimated from natural fluorescence measurements (PNF...
  5. Identification and classification of vertical chlorophyll patterns in the Benguela upwelling system and Angola-Benguela front using an artificial neural network

    Identification and classification of vertical chlorophyll patterns in the Benguela upwelling system and Angola-Benguela front using an artificial neural network

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Information on the vertical chlorophyll structure in the ocean is important for estimating integrated chlorophyll a and primary production from satellite. For this study, vertical chlorophyll profiles from the Benguela upwelling system and the Angola-Benguela front were collected in winter...
