Solution of the transonic integrodifferential equation using a decay function
(University of Nairobi., 1990)
The two-dimensional, small-disturbance, transonic integrodifferential equation is solved by using a decay function that is applicable in the entire computational domain rather than on the airfoil surface only. The computational ...
Root growth, soil water depletion, nitrogen uptake and yield of wheat in relation to irrigation and nitrogen application
(1990)
In a trial in 1984-85 with wheat cv. HD 2009 given 80 or 120 kg N/ha, the values for root penetration and root wt density (RWD) in different soil layers were higher with (a) irrigation at 50% soil water depletion than with ...

(University of Nairobi., 1990)
AdultGlossina morsitans morsitans exposed to wet conidia ofBeauveria bassiana andMetarhizium anisopliae suffered high mortalities ranging from 90 to 100% by 2 weeks post-exposure. Infected ♂ ♂ maintained in the same cages ...
Breeding biology of the Louisiana red swamp crayfish Procambarus clarkii Girard in Lake Naivasha, Kenya
(University of Nairobi, 1990-12-03)
This paper describes the breeding biology of the Louisiana red swamp crayfish (Procambarus clarkii Girard) that has been introduced in a tropical lake, Naivasha. Notable differences in crayfish biology are found between ...
