Flemingins G–O, Cytotoxic and Antioxidant Constituents of the Leaves of Flemingia grahamiana
(2014)The known flemingins A–C (1–3) and nine new chalcones, named flemingins G–O (4–12), along with deoxyhomoflemingin (13) and emodin (14) were isolated from a leaf extract of Flemingia grahamiana. The isolated chalcones were ... -
Flood Forecasting Over Lower Nzoia Sub-basin In Kenya
(University of Nairobi, 2014)Real time flood forecasting is one of the most effective non- structural measures for flood management. In this study, Ensemble Kalman Filter (EnKF) is used with Probability Distributed Moisture model (PDM) to forecast ... -
Flood frequency analysis in lake Victoria basin based on tail behaviour of distributions
(University of NairobiDepartment of Meteorology, 2007)The primary objective of the study was to find a suitable distribution class for flood frequency analysis on the Kenyan side of Lake Victoria basin. This involved performing at-site analysis using Peak Over Thresh-old ... -
