Glutathione S-Transferases: α-Naphthyl Acetate Activity and Possible Role in Insecticide Resistance
(1995)
Rat liver and house fly, Musca domestica L., glutathione S-transferases were purified by affinity chromatography and chromatofocusing. The specific activity with α-naphthyl acetate (a substrate, for general esterase activity) ...
Acaricidal activity of Margaritaria discoidea (Euphorbiaceae) plant extracts against the ticks Rhipicephalus appendiculatus and Amblyomma variegatum (Ixodidae)
(Uniiversity of Nairobi., 1995)
A water soluble extract of M. discoidea, an African indigenous plant induced high mortalities in nymphs of both Rhipicephalus appendiculatus, and Amblyomma variegatum and in adult R. appendiculatus, but not in adult A. ...
Lithostratigraphy, provenance and facies distribution of Archaean cratonic successions in western Kenya
(Elsevier,, 1995)
The greenstone belt of the Tanzanian shield in Western Kenya is composed of two supracrustal successions, which form the Nyanzian and Kavirondian Groups. The Nyanzian Group at the base is composed of mafic tholeiitic ...
Effects of a biologically active fraction from Melia volkensii on Culex quinquefasciatus
(1995)
A chromatographically enriched fraction designated Fraction B from dry fruits of the plant Melia volkensii (family Meliaceae) was evaluated with the objective of determining its toxic and growth inhibiting effects on the ...
Seismic images illustrate the deep roots of the Chyulu Hills volcanic area, Kenya
(1995)
A recent delay time tomography experiment has revealed the still ongoing processes that formed the East African Rift, the world's largest continental rift system. These new data have been used to produce tomographic images ...

The Romanche fracture zone sediments, equatorial Atlantic: main controls on their distribution and composition
(1995)
In the present study, the lithology, mineralogy and chemistry of sediment cores collected from different parts of the
equatorial Atlantic have been investigated in order to determine the factors controlling their composition ...
Chemotaxonomic significance of anthraquinones in the roots of asphodeloideae (asphodelaceae)
(1995)
The distribution of seven anthraquinones in the roots of some 46 species belonging to the genera Asphodelus, Asphodeline, Bulbine, Bulbinella and Kniphofia was studied by TLC and HPLC, 1,8-Dihydroxyanthraquinones based on ...
