  1. Correlation between micro-aggregate stability and soil surface susceptibility to runoff and erosion

    Correlation between micro-aggregate stability and soil surface susceptibility to runoff and erosion

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A simple procedure to determine micro-aggregate stability was developed. The micro-aggregates in aqueous suspension were subjected to controlled energy input imposed by sonic vibration to simulate the breaking down of aggregates by raindrop impact during a rain storm event. The...
  2. Comparison of ultrasound-guided vs. anatomical landmark-guided cannulation of the femoral vein at the optimum position in infant

    Comparison of ultrasound-guided vs. anatomical landmark-guided cannulation of the femoral vein at the optimum position in infant

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Femoral vein cannulation can be a routine process during major surgery in infants and children, and may prove to be lifesaving under certain conditions. This study compared ultrasound (US)-guided cannulation of the femoral vein in infants with the traditional...
