Quantitative aspects of inorganic nutrient fluxes in the Gazi Bay (Kenya): implications for coastal ecosystems
(2002-11)
Fluxes of dissolved inorganic nutrients: NHþ 4 , NO_ 2 , NO_3 , PO3_4 and Si(OH)4 from nearshore sediments of Gazi Bay were measured in situ within mangrove, seagrass and coral reef biotopes using benthic flux bell-jar ...
Preliminary reports on Radon Concentration in Drinking Water and Indoor Air in Kenya
(2002)
A screening survey has been carried out to determine activity concentrations of radon (222Rn) in drinking water and indoor air in various locations in Kenya. The concentration of 222Rn in water was measured using a liquid ...
Isolation and in Vitro antiplasmodial Activities of Alkaloid from Teclea trichocarpa: In Vivo antimalaria activity and X-ray crystal structure of normelicopicine
(2002-07)
Seven alkaloids have been isolated from Teclea trichocarpa including four, normelicopicine (1), arborinine (2), skimmianine (6), and dictamnine (7), that are reported for the first time in addition to the previously reported ...
Flavonoids from Tephrosia aequilata
(University of Nairobi, 2002-06)
From the roots of the plant Tephrosia aequilata Baker, five flavonoids were isolated of which, 3,4:8,9-dimethylenedioxypterocarpan is reported for the first time. Its structure and those of the already known flavonoids ...
Towards Sustainable Charcoal Production and Use: a Systems Approach
(2002)
The majority of African households will continue depending on traditional fuels to meet their
daily energy needs for many decades to come. In particular, the demand for charcoal in most
countries in the region continues ...
Key elements of fisheries management on Lake Victoria
(University of Nairobi, 2002)
The fisheries of Lake Victoria have always been dynamic and the relevant authorities have continually tried to manage them. During the second half of the last century, numerous changes took place and fisheries managers had ...
Biodiversity characteristics of small high-altitude tropical man-made reservoirs in the Eastern Rift Valley, Kenya
(University Of Nairobi, 2002)
The biodiversity characteristics in eight small (0.065–0.249 km2) public man-made reservoirs in the central part of the Eastern Rift Valley, Kenya, were studied between 1995 and 1998. A total of 71 phytoplankton species ...
Development of an exposure-free bednet trap for sampling Afrotropical malaria vectors
(2002)
An exposure-free bednet trap (the 'Mbita trap') for sampling of Afrotropical malaria vectors was developed during preliminary studies of mosquito behaviour around human-occupied bednets. Its mosquito sampling efficiency ...
Development of Reflectance Spectral Libraries for Characterization of Soil Properties
(Soil Science Society of America Journal, 2002)
Methods for rapid estimation of soil properties are needed for
quantitative assessments of land management problems. We developed
a scheme for development and use of soil spectral libraries for
rapid nondestructive ...
Breeding Cycle of Thalamita crenata (Latreille, 1829) at Gazi Creek (Maftaha Bay), Kenya
(2002)
Thalamita crenata (Latreille, 1829) is a crustacean decapod that occurs in inter- and
sub-tidal environments in the main water channels of the eastern Africa coast. The sandy pools
at Gazi creek are areas for artisanal ...
