The reproductive activity of the pearl oyster Pinctada imbricata Röding 1798 (Pteriidae) in Gazi Bay, Kenya
(Department of Zoology, University of NairobiDepartment of Botany, University of Nairobi, 2006)This paper describes the reproductive activity of the pearl oyster Pinctada imbricata Röding 1798 in two adjacent areas in Gazi Bay, Kenya, exposed to different tidal current velocity. The annual mean temperature, salinity, ... -
Abundance and Population Structure of the Blacklip Pearl Oyster, Pinctada margaritifera l. 1758 (Bivalvia: Pteriidae), in Coastal Kenya
(Western Indian Ocean Marine Science AssociationDepartment of Zoology, University of Nairobi, 2002)Pearl oysters are an important marine resource within the Indo-Pacific oceans. They are widely cultured for the production of black pearls, their flesh is eaten, and their shell, known as mother-of-pearl (MOP) is used in ... -
Trophic Ecology of Sardinella gibbosa (Pisces: Clupeidae) and Atherinomorous lacunosus (Pisces: Atherinidae) in Mtwapa Creek and Wasini Channel, Kenya
(Western Indian Ocean Marine Science Association, 2002)The food habits of two schooling planktivorous fishes, Sardinella gibbosa and Atherinomorous lacunosus, were investigated in Mtwapa creek and Wasini Channel of the Kenya coast. Spatial and temporal variations in their food ... -
Thermal shock behaviour of a kaolinte refractory prepared using a natural organic binder
(SpringerDepartment of Physics, University of Nairobi, 2006)The thermal shock resistance of a kaolinite-based refractory prepared with a binder derived from a plant (corchorus olitorius) was investigated. Thermal shock tests employing water-quenching technique were performed at ... -

Biflavanoids of the Cycadales
(1975)Biflavanoid patterns of leaves of 82 species of the order Cycadales comprising 3 families and 10 genera have been determined. The biflavanoids were identified by TLC, UV, NMR and MS studies. Pattern differences between ... -
Antiprotozoal Properties of 16, 17-Dihydroxybrachycalyxolide from Vernonia brachycalyx
(1998)Extracts of the leaves from Vernonia brachycalyx showed in vitro activity against Plasmodium falciparum and promastigotes of Leishmania major. The germacrane dilactone 16,17-dihydrobrachycalyxolide (1) which was previously ... -

Partial characterization and post‐feeding activity of midgut aminopeptidase in the human body louse, Pediculus humanus humanus
(1998)A leucine aminopeptidase was found in the midgut of the human body louse, Pediculus humanus humanus L. (Anoplura: Pediculidae). The enzyme is activated by the bloodmeal with a pH optimum at 8. The enzyme is soluble in both ... -

Elemental Composition of Suspended Particulate Matter Collected at Two Different Heights above the Ground in A Sub-Urban Site in Kenya
(2010)Suspended particulate matter samples were collected in a sub-urban area in Nairobi over a 12 month period at two different heights above ground using a “Gent” SFU sampler. A total of 126 sets of duplicate fine and coarse ... -
Electroreduction of pyridinium carboxylic acids homarine and trigonelline in acidic solutions
(1984)Homarine and trigonelline are reduced at the carboxylic acid group at mercury electrodes in acidic solutions. In dc polarography and cyclic voltammetry, reduction yields the hydrated aldehyde, but controlled-potential ... -
Rate of uptake of cadmium, chromium, lead and zinc ions by roots, stems and leaves of different ipomoea batatas plant varieties under in vitro conditions
(2012)Five sweet potato plant varieties grown in water solutions, containing varying amount of metal ions (Cd, Zn, Pb and Cr), demonstrated different rates of up take of the ions and distribution in leaves, roots and stems. ... -
An investigation of the transport and dispersion of atmospheric pollutants over east Africa during the Ol doinyo lengai volcanic eruption in July 2007 and march 2008
(2012)Explosive volcanic eruptions affect climate by injecting gases and aerosol particles into the troposphere and stratosphere. Only if the eruption cloud is rich in SO2 will the eruption produce a long-lived aerosol cloud, ... -
Voltammetric Studies of the Reactions of Imidazolidine Nitroxyl Free Radical with Vanadium Pentoxide, Chromium (III) Acetate and Manganese (III) Acetylacetonate
(1998)This work demonstrated the synthesis and voltammetric studies of imidazolidine nitroxyl free radical (LH) complexes of chromium, manganese and vanadium. Half-wave potentials of solutions containing the three metal-LH as ... -
