High fluoride concentration in groundwater has made many drilled boreholes unusable for drinking in parts of Northern region of Ghana. Treatment of the groundwater by adsorption is also hampered by the lack of suitable locally available adsorbents. This thesis highlights through principal component analysis and saturation indices calculations that predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes, which deplete Ca from the groundwater, and promote the dissolution of fluorite. Additionally, aluminium oxide coated media is capable of reducing fluoride in water, suggesting it is a promising defluoridation adsorbent.

Investigates the praise poetry genre of the Dagombas of northern Ghana. This book focuses on the art of drumming, performed by court figures known as drummers, that is at the heart of Dagomba culture. It addresses various questions, in addition to how we can channel panegyrics to positive uses.
