    Prevalence and determinants of congenital cytomegalovirus infection at a rural South African central hospital in the Eastern Cape

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    Background: The Nelson Mandela Academic Hospital (NMAH) in Mthatha, Eastern Cape, is a rural central hospital, serving one of the poorest districts in South Africa. The prevalence of and risk factors for congenital cytomegalovirus (CMV) in this area are not...
  2. The dough handling properties of two South African wheats with the 1B/1R chromosome translocation

    The dough handling properties of two South African wheats with the 1B/1R chromosome translocation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Samples of two hard red spring wheats having the 1B/1R translocation were processed with commercial milling and baking equipment. Dough handling properties were noted following low and high speed mixing of the flours. W83/10 flour was totally unsuited for commercial...

  5. A QUANTITATIVE SAMPLER FOR SUBMERGED AQUATIC MACROPHYTES

    A QUANTITATIVE SAMPLER FOR SUBMERGED AQUATIC MACROPHYTES

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    A simple rotary sampler, capable of quantitatively harvesting submerged aquatic macrophytes is described. The sampler can be operated from a boat and consists of a central rod with a specially designed cutting blade at the base, and collecting hooks to...

    CRITICAL POINT DRYING AS A PREPARATIVE TECHNIQUE FOR SCANNING ELECTRON MICROSCOPY AND ITS APPLICATION IN LIMNOLOGY

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The preservation technique of critical point drying for use with the scanning electron microscope is described. A study of the periphyton community development on the aquatic macrophyte, Potamogeton pectinatus L. from the littoral zone of Swartvlei, southern Cape Province, is...
  7. AQUATIC MACROPHYTE COMMUNITIES OF THE WILDERNESS LAKES: COMMUNITY STRUCTURE AND ASSOCIATED ENVIRONMENTAL CONDITIONS

    AQUATIC MACROPHYTE COMMUNITIES OF THE WILDERNESS LAKES: COMMUNITY STRUCTURE AND ASSOCIATED ENVIRONMENTAL CONDITIONS

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The structure and summer biomass (g m−2 dry mass) of the principal aquatic macrophyte communities of the Wilderness Lakes were measured. Both emergent and submerged communities were included in the study. Productivity estimates were made by multiplying biomass by production/biomass...
  8. WETLANDS AND WATERSHED MANAGEMENT: THE ROLE OF AQUATIC VEGETATION

    WETLANDS AND WATERSHED MANAGEMENT: THE ROLE OF AQUATIC VEGETATION

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The single feature which distinguishes wetlands from other aquatic ecosystems is an abundance of aquatic vegetation. This vegetation affects water movements, gas and dissolved chemical exchanges, and sediment transport, and provides a unique microclimate above the water surface. Two roles...
