Removal of sulphates from South African mine water using coal fly ash
(University of the Western Cape, 2009)South African power stations generate large amounts of highly alkaline fly ash (FA). This waste product has a serious impact on the environment. Acid mine drainage (AMD) is another environmental problem associated with ... -
Rendering an avatar from sign writing notation for sign language animation
(University of the Western Cape, 2010)This thesis presents an approach for automatically generating signing animations from a sign language notation. An avatar endowed with expressive gestures, as subtle as changes in facial expression, is used to render the ... -
Reproductive health situation among youth in the Democratic Republic of Congo
(University of the Western Cape, 2015)Background: In the Democratic Republic of Congo, 22.2% of the total population is in the age group of 15 to 24 years. In this country, this population group faces a large number of reproductive health problems. Even ... -
The reproductive physiology of The south african pilchard.
(UWC, 1995)Epipelagic fish species form an integral component of the world's supply of protein. The most abundant of these fish belong to the order Clupeiformes (clupeoids) which include sardine, pilchard, sardinella, sprat, and ... -
Reptile community responses to an avian ecosystem engineer
(University of the Western Cape, 2023)In the Kalahari, sociable weavers (Philetairus socius) build huge, communal nests. Although Kalahari tree skinks (Trachylepis spilogaster) are known to preferentially use trees that host such colonies, the degree to which ... -
Reservoir Characterization of well A-F1, Block 1, Orange Basin, South Africa
(University of the Western Cape, 2018)The Orange basin is relatively underexplored with 1 well per every 4000km2 with only the Ububhesi gas field discovery. Block 1 is largely underexplored with only 3 wells drilled in the entire block and only well A?F1 inside ... -
Reservoir Characterization using Genetic Inversion and Seismic attributes of Block 1 Orange Basin, Offshore South Africa
(University of the Western Cape, 2016)Block 1, Orange Basin is located offshore west coast South Africa. This study is focused on providing a solution to performing reservoir characterization in areas where well data is scanty by generating reservoir models ... -
Reservoir distribution and characterization of lower cretaceous sands in block 2A of Orange Basin, offshore, South Africa.
(University of the Western Cape, 2017)Orange Basin is a volcanic passive margin that forms part of the southwestern basins that were formed during the breakup of South America and Africa in Late Jurassic to Early Cretaceous. The basin comprises of numerous ... -
Reservoir heterogeneity of the sandstone reservoirs within the Pletmos basin, block11a, offshore South Africa
(University of the Western Cape, 2014)This study is aimed at illustrating the reservoir heterogeneity in the BCII - BCI interval of the Ga-field, offshore South Africa. This was achieved by generating a conceptual static model as a predictive tool for the BCII ... -
Reservoir quality, structural architecture, fluid evolution and their controls on reservoir performance in block 9, F-O gas field, Bredasdorp Basin, offshore South Africa
(University of the Western Cape, 2012)The use of integrated approach to evaluate the quality of reservoir rocks is increasingly becoming vital in petroleum geoscience. This approach was employed to unravel the reason for the erratic reservoir quality of ... -
