Studies with antitranspiratis on coffee. (Coffee Arabic L.)
(University of NairobiCollege of biological and physical science, 198) -
Natural and experimental studies on domestic animal infections with visceral and cutaneous leishmaniases in Kenya.
(10/3/2012)The control of visceral and cutaneous leishmaniases in Kenya has been difficult due to poor knowledge of animal reservoirs of these diseases. Little is known about the feeding preferences of phlebotomine sand flies that ... -
Some geomagnetic effects in the equatorial F2-region
(1955)The diurnal variations of the values of many ionospheric parameters obtained at Ibadan, Nigeria, close to the magnetic equator, are investigated on magnetically quiet days and on magnetically disturbed days. It is found ... -
Equatorial ionospheric absorption
(1956)A study has been made of the variation of absorption with frequency and sun's zenith distance χ at Ibadan at vertical incidence. Since the propagation at Ibadan is almost purely transverse, simple theories in terms of ... -
Spread F-layer echoes and radio-star scintillation
(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, ... -
Horizontal drift measurements in the ionosphere near the equator
(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 ... -
The belt of equatorial spread-F
(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 ... -
Equatorial spread-F at Ibadan, Nigeria
(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 ... -
Producing ''twilight sleep in large wild mammals''.

The Palaeomagnetism of some Scottish Tertiary Dykes and their Baked Contacts
(University of Nairobi, 1964)This paper presents results of measurements of the directions of magnetization of dyke samples and the associated baked sediments collected from Ayrshire in Scotland. The results suggest that these reversely and normally ... -
Observations on the transmission of schistosoma haematobium and schistosoma bovis in the lake region of Tanganyika.
(University of Nairobi.Department of Zoology, 1964)Previous investigations have shown that in the Lake Region of Sukumaland, Tanganyika, where Schistosoma haematobium is highly endemic, Bulinus (Physopsis) nasutus is responsible for the transmission of that schistosome in ... -
Delayed Implantation in an Equatorial Fruit Bat
(Department of Zoology, Makerere University College, Kampala, Uganda., 1965)AT Kampala, Uganda (latitude 0° 20' N.), there is an enormous roost of the fruit bat, Eidolon helvum Kerr. Numbers vary seasonally, with a maximum of about 250,000 during October-November -
Effect of adrenalectomy on serum and tissue amylase
(College of Biological Sciences, University of Nairobi, 1965)The influence of the adrenals on the maintenance and control of serum and tissue amylase was studied in rats by determining the amylase content periodically for 21 days after adrenalectomy. Liver, muscle, fat, small ... -
Diurnal Variation of Total Electron Content of the Ionosphere Over Nairobi
(University of Nairobi, 1965-05)THE ionospheric research station at University College, Nairobi, was set up during 1963 in time to commence observations for the I.Q.S.Y. The station has geographic co-ordinates 36.82° E., 1.32° S. and is 10.5° S. of the ... -
Field and laboratory methods for research into the anatomy of east African Game animals
(University of Nairobi, 1966)Descriptions are given of various methods which have been used in the field and in the laboratory to obtain and investigate specimens for comparative studies of the anatomy of East African game animals. Fixation of the ... -
The Climate of Africa by B. W. Thompson

The giraffe of Nairobi National Park: home range, sex ratios, the herd, and food
(University of Nairobi, 1966)The giraffe of Nairobi National Park, Kenya have been studied for one year. Each animal seen has been photographed from the left side and the pattern on the neck used to recognize each individual. While the pattern may ... -
Magnetic Decay in a Hollow Elliptic Cylinder. II
(University of Nairobi, 1966)Earlier results for the relaxation time of an axial magnetic field in a conducting hollow elliptic cylinder are extended to the case of eccentricities near unity. -
Gasteromycentes of East Africa
