Effect of rotenoids from the seeds of Millettia dura on larvae of Aedes aegypti
(University of Nairobi, 2003-10)
A crude chloroform extract of seeds of Millettia dura Dunn (Leguminosae) showed high activity (LC50 = 3.5 µg ml−1 at 24 h) against second-instar larvae of the mosquito, Aedes aegypti L (Diptera: Culicidae). The rotenoids, ...
Triblock copolymers of lactide with poly(ethylene glycol) and influence of stereochemical composition
(2003)
Polymerization of L-lactide (LLA) and poly(ethylene glycol) (PEG) at 120°C using stannous 2-ethyl hexanoate results in ABA triblock copolymers in good yields. The glass transition temperature of the copolymers shows strong ...
Myoglobin coadsorbed on electrodes from microemulsions provides reversible electrochemical catalysis. Langmuir, 2003, 19, 6976
(2003)
The iron heme protein myoglobin (Mb) coadsorbs with surfactant onto glassy carbon, pyrolytic graphite, and platinum electrodes from microemulsions of sodium dodecyl sulfate or cetyltrimethylammonium bromide, water, oil, ...
The onset and cessation of the "Long Rains"in Eastern Africa and their interannual variability
(2003)
Thirty years (1958–1987) of daily rainfall data for Kenya and north eastern Tanzania are analysed with the aim to characterize the interannual variability of the onset and cessation of the East African “long rains” (boreal ...
Transition from the Southern to the Northern Hemisphere summer of zones of active convection over the Congo Basin
(2003)
This study used monthly rainfall totals for the period 1961 to 1988 and pentad OLR values for the period 1974 to 1991 to study the structure and transition of active convention across the Congo Basin (10° S–5° N, 15° E–35° E) ...
