Determination of the optimum tilt angle for photovoltaic modules in Senegal

This paper deals with finding the optimum tilt angle of solar panels for solar energy applications. The objective is to maximize the output electrical energy of the photovoltaic (PV) modules. A mathematical model was used to determine the optimum tilt angle of solar collectors in Senegal on a daily and monthly basis, as well as for a specific period. Then, the configuration of the optimum tilt angle was analyzed by...

Diversity of arbuscular mycorrhizal fungi associated to Sorghum (Sorghum bicolor L. Moench) in soils of Sikasso region (Mali)

In Mali, studies on arbuscular mycorrhizal fungi (AMF) characterization and diversity are still few, despite the important roles played by these microorganisms in plant growth and in degraded soils restoration. Sorghum is one of the staple food grains in Mali and as such plays a key role in food security in Mali. This study aims to determine diversity of AMF strains associated to sorghum in Sikasso region soils in Mali....

Occupational health impacts of climate change across different climate zones and elevations in sub-Saharan East Africa

Climate change will cause Sub-Saharan tropical countries to experience a disproportionate increase in the number of extremely hot days when compared to Western countries with more temperate climates. We use the High Occupational Temperature Health and Productivity Suppression (HOTHAPS) model to estimate the potential impact of rising temperatures on worker productivity in different climate regions within Ethiopia,...

Optimization of oxygen consumption and reduction of organic matter from waste during the fermentation phase: Case of the composting platform in Lomé, Togo

In the context of carbon financing it is required that the rate oxygen inside the windrows exceeds 8% to avoid anaerobic decomposition. Thus, the objective of this study is to optimize oxygen consumption and  reduce organic matter in the waste during the fermentation phase. Windrow turning is monitored, which includes monitoring of temperature, pH, organic matter, humidity and certain metals.Temperature monitoring...
