Use of complexing ligands in the determination of antimony and tin by atomic-absorption spectrometry
(University of Nairobi., 1979-04)
The atomic-absorption spectrophotometric determination of antimony is best achieved in the presence of either an ammonium fluoride, hydrochloric acid, nitric acid mixture, or one of the following complexing agents: tartaric ...
The biting flies of the Kano Plains, Kenya: Part II. Larval habitats of common mosquito species (Dipt., Culicidae
(1971)
This paper describes the results of studies on the chemical and physical characteristics of terrestrial breeding habitats of common mosquito species in the Kano Plains of Kenya. The study was initiated following the decision ...
Negative magnetic anomaly associated with Mount Kenya
(1974-08-16)
MOUNT Kenya is a large central volcano just south of the equator in central Kenya. It rises to a height of 5,199 m above sea level. The base of the volcano covers an area of approximately 7,000 sq km, and is roughly circular ...
Fresnel-type Fading On Satellite Records At Low Latitudes
(University of Nairobi, 1975-08)
Fresnel-type fading patterns have been observed on recordings of geostationary and travelling satellites made at three low-latitude stations in East Africa. The occurrence is greatest in the time periods 05–08 and 18–22 ...
Movements Of Airglow Structures Within The Intertropical Arc Observed From Southern Kenya
(University of Nairobi, 1977)
6300 Å airglow observations from Olorgesailie, Kenya (1.6°S, 36.4°E) show two types of movement within the southern intertropical red arc. The arc moves as a whole equatorwards at a rate of 3–4° per hour before local ...
The Seasonal Occurrence Of Blanketing Sporadic-e Near The Geographic Equator
(University of Nairobi, 1972-06)
It is shown that the latitude at which the occurrence of blanketing sporadic-E (View the MathML source) changes over from a June maximum to a December maximum is south of the geographic equator in the African and Far Eastern ...
Some properties of ionospheric irregularities as deduced from recordings of the San Marco II and BE-B satellites
(University of Nairobi, 1970-07)
Recordings of scintillations on signals received at Nairobi from satellites San Marco II and BE-B have been analysed by correlation and dispersion methods, the correlation method equations being derived in a simpler way. ...
The biting flies of the Kano Plains, Kenya, Part I: A review of their bionomics and suggestions for further research
(University Of Nairobi, 1971)
Basaltic Macadam-breccias In The Girvan-ballantrae Complex, Ayrshire
(University of Nairobi, 1979-09)
Many supposed “volcanic agglomerates and tuffs” in the Girvan-Ballantrae complex of southern Ayrshire are considered to be non-pyroclastic in origin. These macadam breccias are accumulations of lava breccia derived mainly ...
Some Observations of Rotational Remanent Magnetization
