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” ...

Selection of a appropriate model for the interpretation of time-domain airborne electromagnetic data for geological mapping
(1998)
A detailed analysis of the time-domain INPUT airborne electromagnetic response to a horizontal layer of variable conductivity and thickness reveals that there are combinations of conductivity and thickness of the layer for ...
Glacial/interglacial variations in carbon cycling revealed by molecular and isotope stratigraphy of Lake Nkunga, Mt. Kenya, East Africa. Organic Geochemist
(1998)
The lipid content (n-alkanes, n-alkanols, n-alkanoic acids) and the δ13C values of these lipids were measured in nineteen sediment samples taken from a 21.18 m long core from Lake Nkunga, a high-altitude (1820 m a.s.l.), ...
