    • New antitrypanosomal tetranotriterpenoids from Azadirachta Indica 

      Patel, JP; Gacii, P (University of Nairobi, 1972-07)
      Organic extracts of the leaves of Azadirachta indica A. Juss. yielded ten antitrypanosomal terpenoids. Three of these (1 – 3), are novel and are derivatives of nimbolide and nimbin. They were extracted from chloroform fraction ...

    • The paleomagnetism of the Turkana lavas 

      Raja, P. K. S; Reilly, T. A.; Mussett, A. E. (University of Nairobi, 1966-02)
      Directions of magnetizations obtained after cleaning the Miocene lavas from northwest Kenya are presented. The pole position thus obtained, together with similar data from eastern Africa, indicates that no significant ...

    • Horizontal drift measurements in the ionosphere near the equator 

      Skinner, NJ; Hope, J; Wright, RW (University of Nairobi, 1958)
      MEASUREMENTS of horizontal drift in the ionospheric E- and F-layers have been made regularly at Ibadan (magnetic latitude 2½° S.) since June 1957. These measurements are of importance in view of the theory of the origin ...

    • Interference effects of different metals in the atomic absorption spectrophotometric determination of chromium 

      Nyagah, CG; Wandiga, SO (University of Nairobi, 1979)
      The interfering effect of thirty six metal salts on chromium absorbance in the air- acetylene flame has been studied. The interference does not depend on the boiling point of the added foreign metals or particle size as ...

    • The belt of equatorial spread-F 

      Lyon, AJ; Skinner, NJ; Wright, RWH (University of Nairobi, 1960)
      The morphology of the belt of equatorial spread-F at sunspot maximum is investigated, using I.G.Y. data, for magnetically quiet and magnetically disturbed conditions respectively. The belt is found to extend from about ...

    • Spread F-layer echoes and radio-star scintillation 

      Wright, RW; Koster, JR; Skinner, NJ (University of Nairobi, 1956)
      Observations of radio-star scintillations made at University College of the Gold Coast, Achimota, and spread F-layers made at University College, Ibadan, Nigeria, have been compared. Considerable correlation is found, ...

    • Scintillation fading of signals in the SHF band 

      Skinner, NJ; Kelleher, RF (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 ...

    • University of Nairobi Library Magazine 

      Shiraz, D; wadundwe, FE (University of Nairobi, 1978-07)

    • Equatorial spread-F at Ibadan, Nigeria 

      Lyon, AJ; Skinner, NJ; Wright, RW (University of Nairobi, 1961)
      The characteristics of equatorial spread-F at Ibadan (magnetic latitude 3°S) are investigated including nocturnal, seasonal, solar-cycle and magnetic disturbance variations; and all of these are found to show marked ...

    • Terrestrial heat flow in Botswana and Namibia 

      Ballard, S; Pollack, HN; Skinner, NJ (University of Nairobi, 1987)
      We report terrestrial heat flow measurements from 25 new sites in Botswana and Namibia. Twelve sites from the Archean Kaapvaal-Zimbabwe Craton and the Limpopo Belt have a mean of 47 ± 4 mW m−2 (standard error of the mean) ...
