    Abstract : Essay I: How does electricity provision affect female employment? In theory, electrical household appliances can save labor in domestic production and divert it to the market. However, the empirical evidence has been inconclusive. READ MORE

  4. 2. Characterization of Pathfinders and Indicators of Gold

    Author : Gabriel Kofi Nzulu; Martin Magnuson; Per Eklund; Hans Högberg; Farid Akhtar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pathfinder; Indicator; Gold; Hydrothermal; X-ray; Diffraction; Kubi; Ghana;

    Abstract : Research on natural minerals and their chemical bonding to economically critical raw materials is a viable industrially relevant research area due to its increasing demand. Meeting demands requires fast, robust, and efficient techniques to explore new ore deposits and continuous operation of active mines as well as recycling. READ MORE

  5. 3. Mining Booms in Africa and Local Welfare Effects: Labor Markets, Women’s Empowerment and Criminality

    Abstract : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. READ MORE

  7. 5. Characterization of Gold Pathfinder Minerals

    Author : Gabriel Kofi Nzulu; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this Thesis, I investigate the properties of artisanal small-scale gold mining concentrate samples from the Kubi Gold Project of the Asante Gold Corporation near Dunkwa-on-Offin in the Central Region of Ghana with a material science perspective.X-ray diffraction (XRD) is used to identify SiO2 (quartz), Fe3O4 (magnetite), and Fe2O3 (hematite) as the main indicator minerals in the mining site while contributions from pyrite, arsenopyrites, iridosmine, scheelite, tetradymite, garnet, gypsum, and other sulfate minerals were insignificant.
