    Bilateral greater occipital nerve block for headache after corrective spinal surgery: a case report

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Post-dural puncture headache is a common complication for patients with dural puncture and if untreated can result in complications such as subdural hematoma and seizures.

    MIGRATION AND DISPERSAL OF AUDOUIN'S GULL <em>LARUS AUDOUINII</em> FROM THE EBRO DELTA COLONY

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology

  3. Noetherian quivers

    Noetherian quivers

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Noetherian quivers have been studied and characterized (when the number of arrows is finite) by Höinghaus and Richter in [10]. In this paper we give a characterization of noetherian quivers in the most general case in Theorem 3.6. We prove...

               <em>q</em>)-Summing Sequences of Operators

    (<em>p,</em> <em>q</em>)-Summing Sequences of Operators

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A sequence (u j)j∈N of operators inL (X, Y) is a (p, q)-summing multiplier (or (p, q)-summing sequence of operators), in short (u j) ∈l πp, q (X, Y), if there exists a constant C > 0 such that, for...

    <em>L</em> <sup> <em>p</em> </sup>-valued Measures Without Finite <em>X</em>-semivariation for 2 &lt; <em>p</em> &lt; ∞

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We show that for 1 ≤ p < ∞, the property that every L p -valued vector measure has finite X-semivariation in L p (μ, X) is equivalent to the property that every continuous linear map from l...
  6. DNA sequences from the Little Brown Bustard <em>Eupodotis humilis</em> suggest its close phylogenetic relationship to the Little Bustard <em>Tetrax tetrax</em>

    DNA sequences from the Little Brown Bustard <em>Eupodotis humilis</em> suggest its close phylogenetic relationship to the Little Bustard <em>Tetrax tetrax</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Taxonomic classification of birds based exclusively on morphology and plumage traits has often been found to be inconsistent with true evolutionary history when tested with molecular phylogenies based on neutrally evolving markers. Here we present cytochrome-b gene sequences for the...
  7. <em>Felicitas Publica</em> and community well-being: nourishing relational goods through dialogic conversations between deprived and privileged populations

    <em>Felicitas Publica</em> and community well-being: nourishing relational goods through dialogic conversations between deprived and privileged populations

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    This article discusses the theoretical justifications, presumed relevance and value of using community interventions designed to be appreciative and strengths based, participatory and conversational, context sensitive and value driven, to promote well-being actions and coordinated meaning between privileged persons and...
  8. The dynamics of local innovations among formal and informal enterprises: Stories from rural South Africa

    The dynamics of local innovations among formal and informal enterprises: Stories from rural South Africa

    Exploiting the developmental potential of innovation for marginalised communities requires a context-specific understanding of the features and mechanics of innovation. In this article we explore the nature of innovation with the aid of evidence collected from formal and informal enterprises...
