The Montgenevre ophiolite (Hautes Alpes, France): Meta—morphism and trace-element geochemistry of the volcanic sequence
(University of Nairobi, 1980)
The Montgenevre ophiolite near Briançon in the French Alps consists of pillow lavas, pegmatitic and flaser gabbros and serpentinite in tectonic contact. These rocks have been metamorphosed under prehnite—pumpellyite to ...
Thermodynamic and kinetic aspects of formation of bauxites
(University of Nairobi, 1987)
Experiments in which cleavage nepheline samples were reacted with aqueous solutions at fixed pH's and temperature were carried out in the laboratory. The chemistry of the solution as a function of time was monitored, as ...
A newly found jet in North Kenya (Turkana Channel)
(University of Nairobi, 1982-11)
On the basis of recent pilot balloon observations which have become available in northern Kenya, it is shown that there exists a strong southeasterly low-level jet in the Turkana Channel which separates the Ethiopian ...
Genetics of the mimetic African butterfly Hypolimnas misippus: hindwing polymorphism
(University of Nairobi,, 1989)
The hindwing polymorphism in Hypolimnas misippus is autosomal but sex-limited to the female. It is characterised by three intergrading phenotypes, orange, low white (white in 1–3 intervein spaces) and high white (white in ...
Mean motion field in East Africa at the level of the East African low level jet core
(University of Nairobi, 1985)
The mean flow over East Africa at the 1.5 km level during May through September is presented. All available daily wind vectors from 1952–1973 for 22 pilot balloon stations were used.
The southeast-southwest monsoon ...
Dietary sources of fluoride in Kenya
(1983)
Analysis offluoride concentrations in Kenyan waters have been carried out using two methods: the fluoride ion selective electrode method and colorimetric method. Water samplesanalysed were taken from boreholes and rivers ...
Seasonal population changes and malaria transmission potential of Anopheles pharoensis and the minor anophelines in Mwea Irrigation Scheme, Kenya
(1989)
A study in 1984 and 1985 showed that Anopheles gambiae s.l. and An. pharoensis were the major anophelines in Mwea Irrigation Scheme, Kenya, constituting 83.86% and 15.69% of the catch respectively. Four minor species made ...
Insect podborer infestations and their influence on developing pods and final seed yields by pigeonpea (Cajanus cajan) in Kenya.
(1980)
In Kenya, 8 species of insects were found to be common borers into the developing pods of pigeon pea (Cajanus cajan), feeding on the developing seeds and reducing seed yield. They were Heliothis armigera (Hb.), Maruca ...
