Exploring Below Ground Complementarity In Agroforestry Using Sap Flow And Root Fractal Techniques
(University of Nairobi, 1998-11)
Indices of shallow rootedness and fractal methods of root system study were combined with sapflow monitoring to determine whether these ‘short-cut’ methods could be used to predict tree competition with crops and complementarity ...
Spatial and Inter Annual Patterns of the Surface Temperatures Over East Africa
(University of Nairobi, 1998)
In this study inter-annual patterns of the surface temperature are investigated in order to determine the major climatic fluctuations within the period 1943-1983. The spatial similarities in the observed fluctuation pattern ...
Vector competence of 7 rhipicephalid tick stocks in transmitting 2 Theileria parva parasite stocks from Kenya and Zimbabwe
(1998)
The competence of 7 different stocks of Rhipicephalus appendiculatus and R. zambeziensis to transmit 2 different stocks of Theileria parva was compared by feeding nymphae of each tick stock simultaneously on infected cattle ...
Step-wise screening of defective factors
(Marcel Dekker, Inc., 1992)
It is generally assumed that the defective factors of a
population have the same a-priori probability" of being defective'.
However, with some knowledge of the population, we can relax on
this assumption and assume the ...
Two new species of Meliola from Kenya
(1999)
Meliola periplocae and M warburgiae are described and illustrated in this study from
collections on Periploca linearifolia and Warburgia ugandensis respectively. Periploca is a
new host genus for Meliola, and M warburgiae ...
Lithology, colour and mineralogy of pelagic sediments from the Romanche fracture zone (RFZ) in the equatorial atlantic
(1992)
Sediment cores from the Romanche Fracture Zone (RFZ) in the equatorial Atlantic have been described visually and microscopically as well as analyzed by X-ray diffraction techniques in order to study the main controls on ...
Beach erosion: case studies on the East African Coast
(1992)
Marine erosion of late Holocene beach deposits is a common problem on the equatorial
coasts of the western Indian Ocean, damaging or threatening tourism-related investment
and communication infrastructure. The problem ...
Delineation of Uganda into climatological rainfall zones using the method of principal component analysis
(1995)
This paper attempts to delineate Uganda into climatological rainfall zones using the method of principal component analysis (PCA). Monthly rainfall records from 102 Uganda rain-gauge stations for the years 1940–1975 inclusive ...
DifiFerentiation of Vector Species of Phlebotominae (Diptera: Psychodidae) in Kenya by Chorionic Sculpturing of Their Eggs
(Entomological Society of America, 1992)
Chorionic sculpturing on eggs of Phlebotomus pedifer Lewis, Mutinga, and Ashford; the closely related Phlebotomus aculeatus Lewis, Minter, and Ashford (=P. elegonensis Ngoka, Madel, and Mutinga); and Phlebotomus martini ...
Potent Antimalarial Activity of the Alkaloid Nitidine, Isolated from a Kenyan Herbal Remedy
(1995)
Bioassay-guided fractionation of extracts of Toddalia asiatica, a plant used by the Pokot tribe of Kenya to
treat fevers, has yielded the alkaloid nitidine as the major antimalarial component. Fractions containing
nitidine ...
