Magnetic Grains in Bombay Columnar Basalts
(University of Nairobi, 1971-11)
THE origin of columnar jointing in basalt has been discussed by several authors1, but the origin of many features of the columnar basalts is still controversial. Some magnetic studies of individual columns have been made ...
Scintillation fading of signals in the SHF band
(University of Nairobi, 1971)
IN September 1970, the Mount Longonot satellite telecommunication station, situated in the Rift Valley thirty miles north-west of Nairobi, was put into commercial operation by the East African External Telecommunication ...
Interpretation of Late Precambrian Palaeomagnetic Results from Africa
(University of Nairobi, 1971-12-17)
An apparent polar wander path for the Late Precambrian of Africa is proposed. It is defined by new data from Kenya and Tanzania covering the period 800 My to 1000 or 1100 My, and with an average polar wander rate of about ...
The Palaeomagnetism of the Kisii Series, Western Kenya
(University of Nairobi, 1971-12-17)
The Precambrian Kisii Series in Western Kenya is unmetamorphosed and contains andesites, rhyolites, quartzites and basalts. The basalts, for which a minimum K-Ar age of 930 My is cited, were sampled at 15 sites, and after ...
Effect of Atrazine on Physiological Processes in Leaves
(University of Nairobi, 1971)
We fed 2-chloro-4-(ethylamino)-6-(isopropylamino-s-triazine (atrazine) through the base of excised leaves of atrazine-tolerant and -susceptible species. Atrazine suppressed CO2 uptake in all species. This was shown to be ...
Actions of prolactin on human renal function
(University of Nairobi, 1971)
The action of sheep prolactin on human renal function was investigated in conscious, adult, male volunteers. The prolactin was given by intramuscular injection, and the dose used was within the physiological range for ...
Sequence and geochronology of the Kenya rift volcanics
(University of Nairobi, 1971)
The Upper Cenozoic volcanic formations associated with the Kenya rift valley are divided into seven main stratigraphic groups representing widespread ‘plateau’ formations, and a number of central volcano groups of more ...
