5. 9. Characterization of Gold Pathfinder Minerals

   Författare :Gabriel Kofi Nzulu; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : 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.

7. 10. Sensory qualities and culinary utility of produce : a path towards sustainable gastronomy

   Författare :Magnus Westling; Åsa Öström; Stefan Wennström; Michael Bom Frøst; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Culinary action; culinary arts; cultivated diversity; food design; food science; gastronomic potential; gastronomy; gray peas; meal science; sensory science;

   Sammanfattning : The underlying assumption throughout this thesis is that the continuity of a cultivated diversity can be strengthened by investigating its sensory qualities and specifying particular culinary utilities of landraces and cultivars. How can a foodstuff’s sensory qualities and culinary utility be explored, tested, and refined together with the food industry and the public meal? This thesis aims to create a path toward sustainable gastronomy with greater sensory variation that originate from a cultivated diversity. LÄS MER
