  1. Usage of antibiotics in the intensive care units of an academic tertiary-level hospital

    Usage of antibiotics in the intensive care units of an academic tertiary-level hospital

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    Background: The post-antibiotic era is approaching fast as multidrug-resistant bacteria emerge and the antibiotic pipeline slows to a trickle. Antibiotic stewardship requires that antibiotics be used appropriately and as such this study reviewed the utilisation of antibiotics in five adult...
  2. Habitat management in control of <em>Astylus atromaculatus</em> (Coleoptera: Melyridae) in maize under subsistence farming conditions in South Africa

    Habitat management in control of <em>Astylus atromaculatus</em> (Coleoptera: Melyridae) in maize under subsistence farming conditions in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Studies were conducted in South Africa to assess the potential role of a habitat management strategy developed for the control of cereal stemborers in control of Astylus beetle. This strategy involves intercropping maize with a stemborer moth-repellent fodder plant (Desmodium)...
  3. On symmetric <em>f</em>-biderivations of lattices

    On symmetric <em>f</em>-biderivations of lattices

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we introduce the notion of symmetric f-biderivation on lattices and investigate some related properties.
  4. On boundary layer flow of a Sisko fluid over a stretching sheet

    On boundary layer flow of a Sisko fluid over a stretching sheet

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, the steady boundary layer flow of a non-Newtonian fluid over a nonlinear stretching sheet is investigated. The Sisko fluid model, which is combination of power-law and Newtonian fluids in which the fluid may exhibit shear thinning/thickening behaviors,...
  5. Remediation of eutrophic water using <em>Lemna minor</em> in a controlled environment

    Remediation of eutrophic water using <em>Lemna minor</em> in a controlled environment

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The growth response of common duckweed Lemna minor was studied at various temperature and pH levels for its possible application for remediating eutrophic waters. The dry weight, chlorophyll a, nitrogen, phosphorus, potassium, peroxidase (POD), catalase (CAT) and malondialdehyde (MDA) levels...
  6. Commutativity of rings involving additive mappings

    Commutativity of rings involving additive mappings

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Let R be an associative ring. In the present paper, we investigate commutativity of a ring admitting an additive mapping F satisfying any one of the following properties: (i) F ([x, y]2 ) = F ([x2 , y2 ]), (ii)...
  7. Evaluation of three adjusting manoeuvres and type of endotracheal tube in the success of air-Q™ aided tracheal intubation

    Evaluation of three adjusting manoeuvres and type of endotracheal tube in the success of air-Q™ aided tracheal intubation

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: The present study observed whether the use of three different adjusting manoeuvres and use of an armoured tracheal tube would increase the success rate of tracheal intubation, aided by the air-Q™ intubating laryngeal airway (air-Q™ ILA).
