  1. EXPLORING CARBON CYCLING IN SELECTED MICRO-ORGANISMS EXPOSED TO TERRESTRIAL CARBON SEQUESTRATION
    Chen, Jou-an, 2014-10-27, University of the Free State
    South Africaâs economy is primarily driven by the utilization of coal to provide electricity, which results in more fossil fuels to be burnt that contributes towards global warming. The average daily temperature is estimated to rise between 1.1 to 6.4ËC by 2100. Carbon sequestration is a technology ...

  5. FLOW CHARACTERISTICS OF GROUNDWATER SYSTEMS: AN INVESTIGATION OF HYDRAULIC PARAMETERS
    Leketa, Khahliso Clifford, 2013-05-24, University of the Free State
    The Institute for Groundwater Studies (IGS) undertook a groundwater surface water interaction project under the funding of Water Research Commission starting July 2010. The Modder River was identified as an appropriate study area since it is located downstream of Krugersdrift Dam and has only been i ...
  6. GAS BUBBLE FORMATION IN THE CYTOPLASM OF YEAST
    Dithebe, Khumisho, 2014-08-20, University of the Free State
    It has previously been implicated in literature that intracellular gas bubbles cannot form in yeast cells even under high gas supersaturation conditions. Furthermore, not even protein-coated gas vesicles found in Cyanobacteria are expected in yeasts. The lack of intracellular gas bubbles has been at ...
  7. GENETIC ORIGINS OF THE INTRODUCED PEA WEEVIL (BRUCHUS PISORUM) POPULATION IN ETHIOPIA
    Scheepers, Loraine Cornelia, 2013-05-17, University of the Free State
