A fluorescence spectroscopic study of a coagulating protein extracted from Moringa oleifera seeds
(Elsevier B.V. www.elsevier.com/locate/colsurfb, 2007)
The fluorescence studies of coagulating protein extracted from Moringa oleifera seeds have been studied using steady-state intrinsic fluorescence.
The fluorescence spectra are dominated by tryptophan emission and the ...
Determination of magnetite grain-size using the Hopkinson effect - examples from Botswana rocks
(Botswana Geoscientists Association, 2001)
The Hopkinson effect is the increase of magnetic susceptibility with temperature from near room temperature to near the Curie point. Although this effect has been known for more than a century, it has not been effectively ...
Characterization of enriched lithospheric mantle components in ∼2.7 Ga Banded Iron Formations: An example from the Tati Greenstone Belt, Northeastern Botswana

(Elsevier http://www.doi:10.1016/j.jenvman.2005.03.007, 2005)
This paper uses the concept of sustainable development to examine the utilisation of wildlife resources at Moremi Game Reserve (MGR) and Khwai community area (NG 18/19) in the Okavango Delta, Botswana. Using both secondary ...
Forecasting the spatial extent of the annual flood in the Okavango delta, Botswana
(Elsevier http://www.doi:10.1016/j.jhydrol.2003.11.010, 2004)
The pristine Okavango Delta wetland of northern Botswana is potentially under threat due to water abstraction from its
tributaries. We have developed a statistical model which makes it possible to predict the extent of ...

This paper draws on the dependency paradigm to explain the development of enclave tourism and its socio-economic impacts in the Okavango Delta, Botswana. Using both primary and secondary data source, the study indicates ...
The Karoo triple junction questioned: evidence from Jurassic and Proterozoic 40Ar/39Ar ages and geochemistry of the giant Okavango dyke swarm (Botswana)
(Elservier www.elsevier.com/locate/epsl, 2004)
The lower Jurassic Karoo–Ferrar magmatism represents one of the most important Phanerozoic continental flood basalt
(CFB) provinces. The Karoo CFB province is dominated by tholeiitic traps and apparently radiating giant ...
