  1. The efficacy of ultrasound-guided oblique subcostal transversus abdominis plane block in patients undergoing open cholecystectomy

    The efficacy of ultrasound-guided oblique subcostal transversus abdominis plane block in patients undergoing open cholecystectomy

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Ultrasound-guided oblique subcostal transversus abdominis plane (TAP) blockade has been described recently as providing a wider analgesic blockade than the posterior approach, with the possibility of being suitable for surgery both superior and inferior to the umbilicus. The objective...
  2. Tramadol and postoperative shivering in patients undergoing open and laparoscopic cholecystectomy under general anaesthesia

    Tramadol and postoperative shivering in patients undergoing open and laparoscopic cholecystectomy under general anaesthesia

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: For many years, shivering after anaesthesia has been recognised, and is one consequence of perioperative hypothermia. Shivering affects a number of physiological parameters. The aim of the study was to evaluate the severity of hypothermia after open and laparoscopic...
  3. Die evaluering van vier <em>Eragrostis curvula</em> ekotipes met weidende skape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The evaluation of four Eragrostis curvula ecotypes with grazing sheep. Four ecotypes of Eragrostis curvula, namely, Cape Province 5, Ermelo, Pearston 204 and Makwassie 150 were evaluated in a grazing trial with sheep, at three stocking rates, during two growing...
  4. Effect of planting time on yield and fruit size of open-planted strawberries in the Transvaal

    Effect of planting time on yield and fruit size of open-planted strawberries in the Transvaal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of three planting times (fortnightly intervals) on strawberry cultivars Selekta, Tioga, Parfaite and Rolinda was studied for two seasons. There was no cultivar × planting time interaction, and the yield of all cultivars was significantly reduced from earlier...
  5. Clay-substrate application to sandy open-cast mine soils

    Clay-substrate application to sandy open-cast mine soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The review gives some insight into the objective of amelioration to improve fertility of sandy soils. The research concept is based on the high water and cation exchange capacity of clay minerals. Technological and economic problems as well as practicable...
  6. Host suitability of selected South African maize genotypes to the root-knot nematode species <em>Meloidogyne incognita</em> race 2 and <em>Meloidogyne javanica</em>: A preliminary study

    Host suitability of selected South African maize genotypes to the root-knot nematode species <em>Meloidogyne incognita</em> race 2 and <em>Meloidogyne javanica</em>: A preliminary study

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirty-one commercial maize (Zea mays L.) hybrids and open-pollinated varieties (OPV’s) were screened in separate greenhouse trials with a resistant inbred line MP712W as reference genotype for host suitability to Mel-oidogyne incognita race 2 and Meloidogyne javanica. Approximately 10 000...
  7. Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cultivar selection for different hydroponic production systems is an important management decision, potentially impacting the tomato grower’s profitability. Knowledge on the performance of tomato cultivars, in specific hydroponic systems (open-bag and closed system) under South African conditions, is still very...
  8. <em>D</em>-connectedness

    <em>D</em>-connectedness

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The aim of this paper is to study the categorical topological notion of connectedness in terms of a rather arbitrary class of morphisms in a category. We propose a general approach to the notion both at the morphism and the...
  9. Ideals in Heyting Semilattices and Open Homomorphisms

    Ideals in Heyting Semilattices and Open Homomorphisms

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Subfitness and its relation to openness and completeness is studied in the context of Heyting semilattices. A formally weaker condition (c-subfitness) is shown to be necessary and sufficient for openness and completeness to coincide. For a large class of spatial...
  10. PHYSICAL, CHEMICAL AND BIOTIC RESPONSES TO DECREASING WATER DEPTH IN A HIGHVELD PAN FOLLOWING WET AND DRY SUMMERS

    PHYSICAL, CHEMICAL AND BIOTIC RESPONSES TO DECREASING WATER DEPTH IN A HIGHVELD PAN FOLLOWING WET AND DRY SUMMERS

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    The classification of highveld pans by Geldenhuys (1982) emphasized the spatial diversity of morphology, vegetation and fauna. However, since the characteristics of individual pans also change seasonally and over longer term wet/dry cycles, he called for more detailed limnological studies...
