Integrated Remote Sensing and Geophysical Investigations of the Geodynamic Activities at Lake Magadi, Southern Kenyan Rift
(Department of Geology, University of Nairobi, 2012)The tectonic lineaments and thermal structure of Lake Magadi, southern Kenyan rift system, were investigated using ASTER data and geophysical methods. Five N-S faults close to known hot springs were identified for geoelectric ... -
Irritant Principles of Mezereon Family (thymeleaceae), New skin irritants and tumour promoters of the daphnane and 1, 2-alkyldaphnane type from Synaptolepis kirkii and S. Retusa.
(University of NairobiCollege of biological and physical science, 1988)Seventeen mostly new, skin irritant diterpene esters (DTE) of the daphnane and 1 alpha-alkyldaphnane types were isolated from roots of Synaptolepis kirkii and Synaptolepis retusa. The parent alcohols of the daphnane types ... -
