  1. Design basics of a small hydro turbine plant for capacity building in sub-Saharan Africa

    Design basics of a small hydro turbine plant for capacity building in sub-Saharan Africa

    This paper presents a simplified design considerations for a propeller hydro-turbine, including tabulated relevant mathematical expressions of operating parameters. In the design calculation, a 2.5 m head and 0.183 m3/s flow rate were used as river data for power of...
  2. Electricity insufficiency in Africa: A product of inadequate manufacturing capacity

    Electricity insufficiency in Africa: A product of inadequate manufacturing capacity

    Energy availability is fundamental and crucial for human survival and for national economic development. Energy consumption per capita of a country or region is a measure of quality of life and industrialisation of a country or region. This to certain...
  3. Performance and emission evaluation of pure biodiesel from non-edible feedstock and waste oil in a diesel engine

    Performance and emission evaluation of pure biodiesel from non-edible feedstock and waste oil in a diesel engine

    Biodiesel prepared from Jatropha, Moringa and restaurant waste oil were evaluated in a 3.5 kw diesel engine to determine their performance and pollutant emission. The brake specific (BS) emissions across the full load spectrum were benchmarked against the United States Environmental...
  4. Functionally graded metal matrix composite by centrifugal casting technique mathematical correlation

    Functionally graded metal matrix composite by centrifugal casting technique mathematical correlation

    The functionally graded materials (FGMs) solidification process has complicated movement phenomena of fluid, solute and heat. These phenomena control the segregation of particles in a molten matrix, interactions of particles with a solidification front and the integration of particles in...
  5. Modelling and performance of an automated small hybrid plant

    Modelling and performance of an automated small hybrid plant

    Small rivers that can generate useful quantities of electricity are freely and proportionally distributed in Africa. Thousands of potential sites are available in South Africa, capable of generating hundreds of megawatts. Small hydropower generation is not a new approach in...
  6. Understanding the combined effect of soil properties on gully erosion using quantile regression

    Understanding the combined effect of soil properties on gully erosion using quantile regression

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The individual effects of soil properties on soil erodibility are well understood. It is also known that various interactions between these properties exist, which creates the need for unique investigations into how soil properties influence soil stability. Quantile regression was...
  7. The dimensionality of the Work Related Flow Inventory (WOLF): a South African study

    The dimensionality of the Work Related Flow Inventory (WOLF): a South African study

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    The objective of this study was to validate and explore the factor structure of the Work-Related Flow Inventory (WOLF) as a measure of flow within the South African work context. The sample consisted of N = 415 employees from various organisations in...
  8. Agroforestry Research in the Miombo Ecozone: Experiences of the Southern Africa

    Agroforestry Research in the Miombo Ecozone: Experiences of the Southern Africa

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    The Southern Africa AFRENA embraces four SADC countries, namely Malawi, Tanzania, Zambia and Zimbabwe which are characterised by the miombo vegetation and a unimodal rainfall regime. The research programme has focused on technology development to address small holder farmer problems...
