Neurotrophic And Antileukemic Daphnane Diterpenoids From Synaptolepis Kirkii
(University of Nairobi, 2002-10)
Biological assay guided fractionation of a dichloromethane extract of Synaptolepis kirkii led to the isolation of four new and five known daphnane-type diterpene orthoesters, whose structure was established by spectroscopic ...
Chemical Constituents And Biological Activities Of Zanthoxylum Usambarense
(University of Nairobi, 2002-02)
Bioassay-guided fractionation of the dichloromethane extracts of the roots and the bark of Zanthoxylum usambarense led to the isolation of two physiologically active compounds, i.e. canthin-6-one 1 (fungicide) and pellitorine ...
Ground Thermal Profiles from Mount Kenya, East Africa
(University of Nairobi, 2004-06)
This paper presents and compares ground thermal regimes at 4200 and 4800 m a.s.l. on Mount Kenya's southern aspect. Temperatures were recorded using Tinytalk™ data loggers, installed at the ground surface and at depths of ...
Computing research challenges and opportunities with grid computers
(2008)
Grid computers are integrated environments in which software and hardware resources are pooled in ways that
give any user the impression of working with a single fast computer. This paper examines the current advances
in ...
Agent-based Scheduler for Unrelated Parallel Machines using a load balancing heuristic
(2009)
The problem of finding an optimal schedule for n independent jobs on m non-identical machines is considered.
Several solutions to this problem have been proposed but most of them do not scale well due to the large ...
