Signalization options to improve capacity and delay at roundabouts through microsimulation approach: A case study on arterial roadways in Ghana.
Roundabouts are very useful when flows are balanced but can have operational challenges when flows increase. Most roundabouts on arterial roadways in Ghana experience recurring congestion during peak traffic. The four roundabouts between Ejisu Municipality and Asokwa Municipality on the N6 highway are typical of the situation found on arterials countrywide. -

Diagnosing institutional logics in partnerships and how they evolve through institutional bricolage: Insights from soybean and cassava value chains in Ghana
Trade globalisation and climate change pose new challenges for food security in Africa. To unlock smallholder productivity, more understanding is needed of the institutional context and the role of development interventions, such as partnerships, in the food sector. This article proposes institutional logics as a theory and methodology for institutional diagnosis to gain insight into context-embedded negotiation and change processes created by project-based partnership interventions. -

Photoelectrochemical degradation of methylene blue dye under visible light irradiation using EG/Ag-ZrO2 nanocomposite electrodes
The present study reports the application of three electrodes, consisting of exfoliated graphite (EG), EG and zirconium oxide (EG-ZrO2), and EG and silver-doped zirconium oxide (EG/Ag-ZrO2) in a comparative photoelectrochemical degradation of methylene blue (MB) dye in water under visible light irradiation. -
