Magnetic measurements as a proxy for car pollution in Gaborone
(BOSHASTED, 2000)
Emissions of vehicles represent a significant contribution to environmental pollution along roads. Pollutants from cars include gases such as (NOx, CO, CO2), solid components such as sort particles from exhaust system, ...
Ages of detrital zircon grains from Neoproterozoic siliciclastic rocks in the Shakawe area: implications for the evolution of Proterozoic crust in northern Botswana
(Geological Society of South Africa. http://sajg.geoscienceworld.org/, 2000-06)
The Precambrian rocks of northern Botswana comprise poorly exposed igneous complexes, high-grade metamorphic
rocks, as well as sedimentary sequences including mainly siliciclastic and carbonate rocks. New U-Pb SHRIMP
data ...
The phase separation behaviour and the viscoelastic properties of particles with non-adsorbing polymers: Part I - Experimental study
(Elseview Science B.V. www.elsevier.nl/locate/colsurfa, 2000)
A series of well characterised cis-polyisoprene polymers have been added to dispersions of PHS coated PMMA particles in dodecane. At a molecular weight of 8000 g mol−1 and above, these systems showed phase separation at ...
Land tenure and management reforms in East and Southern Africa - the case of Botswana
(Elsevier Science Ltd. http://www.elsevier.com/locate/landusepol, 2000)
Since attainment of independence, almost every country in East and Southern Africa has introduced some kind of land reform
aimed at reconciling indigenous land tenure practices and those introduced by colonial regimes. ...
A bichalcone from the twigs of Rhus pyroides
(Elsevier Science Ltd, http://www.elsevier.com/locate/phytochem, 2000)
The twigs of Rhus pyroides yielded a novel bichalcone 2',40,21-trihydroxy-4',41-dimethoxy-4-O-51-bichalcone. It was identified on the basis of spectroscopic data including 1D and 2D NMR spectroscopy. The name rhuschalcone-1 ...
Identification of sources of aerosol particles in three locations in eastern Botswana
(American Geophysical Union, https://agupubs.onlinelibrary.wiley.com/journal/21562202, 2000-07-27)
Airborne particles have been collected using a dichotomous virtual impactor at three different locations in the eastern part of Botswana: Serowe, Selibe‐Phikwe, and Francistown. The particles were separated into two fractions ...
