(1980)
The population dynamics of Pineus pini (Gmel.) was examined in two locations in the Kenya Highlands where the mean annual precipitation ranges from 620 to 1400 mm. Variations in population densities were related to rainfall. ...
Alkaloids of Teclea nobilis
(University of Nairobi, 1988)
A new furoquinoline alkaloid to which we have assigned the trivial name nobiline, and seven other quinonline alkaloids were isolated and identified from the leaves and fruits of Teclea nobilis, an African medicinal plant.

Macrotermes michae/seni, a dominant invertebrate herbivore
in the semi-arid savanna of Kajiado, Kenya, was studied to establish
what measures its foragers adopt to counteract ant predation

An Investigation of the Equatorial Orographic–Dynamic Mechanism
(University of Nairobi, 1985)
A barotropic model over an equatorial beta-plane is used to investigate the response when a uniform zonal current crosses an isolated hypothetical mountain centered at the equator. The bounded derivative initialization ...

Mutagenicity Testing of Herbicides, Fungicides and Insecticides I Chromosome aberrations in Vicia faba
(University of Nairobi, 1981)
The insecticides: summithion, lannate, carbicron, thiodan and kelthane, the fungicides: diathane M-45 and aladrin and the herbicides: ramrod, lasso, round up and grammoxone induce acute mitostatic effects of Vicia faba ...
Distribution of repetitive DNA sequences in Vicia faba chromosomes
(University of Nairobi,, 1980)
In situ hybridization of labelled complementary RNA transcribed from whole DNA to metaphase chromosomes indicates the presence of repetitive DNA in both euchromatin and heterochromatin of the Vicia faba genome.
The effectiveness of metrifonate in reducing hookworm infection in Kenyan school children.
(1986)
The reduction in hookworm egg counts was determined in children treated with 1 and 2 doses of metrifonate. Kenyan primary school children were allocated to receive either 10.0 mg (n = 53) or 7.5 mg (n = 53) of metrifonate ...
