Some physiological studies of diazotrophic bacteria associated with maize in a temperate and a tropical soil In:Nitrogen fixation with Non-legumes
(1998)
Previous studies on Azospirillum spp. (Day and Dobereiner, 1976) and Klebsiella oxytoca isolated from wheat roots in Turkey (Cakmacki et al., 1981) indicated little activity below 24°C and high activity at 30–40°C In this ...
The metabolism and distribution of [14c-phenyl]-ethyl parathion in a tropical soil under field conditions
(1998)
The persistence, distribution and metabolism of [14C-phenyl]-ethyl parathion applied to soil
columns in an agricultural farm were investigated under tropical field conditions. Volatilization,
soil microbial activity, ...
The “picnic” model for research training at African Universities: evaluation and preliminary comparison
(University of Nairobi., 1998)
What distinguishes the “Picnic” model for research training at African universities from more classical models is reviewed and it is shown how the “Picnic” model deals with remaining drawbacks from the now popular “Sandwich” ...
Voltammetric Studies of the Reactions of Imidazolidine Nitroxyl Free Radical with Vanadium Pentoxide, Chromium (III) Acetate and Manganese (III) Acetylacetonate
(1998)
This work demonstrated the synthesis and voltammetric studies of imidazolidine nitroxyl free radical (LH) complexes of chromium, manganese and vanadium. Half-wave potentials of solutions containing the three metal-LH as ...
Plant disease data in planning for sustainable use of African mountain forest resources: Problems and opportunities.

The Effects of a DNA Virus Infection on the Reproductive Potential of Female Tsetse Flies, Glossina morsitans centralis and Glossina morsitans morsitans (Diptera: Glossinidae)
(University of Nairobi, 1998)
Reproductive anomalies associated with the tsetse DNA virus infection in the female tsetse hosts, Glossina morsitans centralis Machado and Glossina morsitans morsitans Westwood, inoculated with the virus during the 3rd ...
Sp1 sites mediate activation of the plasminogen activator inhibitor-1 promoter by glucose in vascular smooth muscle cells.
(University of Nairobi, 1998)
This study was designed to characterize the direct effects of hyperglycemia on plasminogen activator inhibitor-1 (PAI-1) expression in cultured vascular smooth muscle cells. Glucose induced dose- and time-dependent increases ...
