Urban water scarcity management: civic vs. state response in Bulawayo
(Pergamon, www.elsevier.com/locate/habitatint, 2002)In most sub-Sahara African cities, rapid urbanization has placed a heavy burden on available human, financial and socioeconomic resources. The problem has been compounded by the intricate and interactive effects of rapid ... -
A continental scale water balance model: a GIS-approach for Southern Africa
(Pergamon www.elsevier.com/locate/pce, 2003)A distributed GIS-based hydrological model is developed using GIS and computational hydrology techniques. The model is based on water balance consideration of the surface and subsurface processes. The surface water balance ... -

(Elsevier http://www.linkinghub.elsevier.com/retrieve/pii/S0016706108001365, 2008)The dynamics of the process of self-filtration in soil columns have been evaluated for two soils with different structural cohesion (Balkuling agricultural soil and a mining residue) by carrying out experiments focusing on ... -
Effects of prolonged UV-B exposure in plants
(Academic Journals. http://www.academicjournals.org/AJB, 2008)Over the past few decades, there has been a depletion of the stratospheric ozone layer due to emissions of halogen-containing compounds of anthropogenic origin. This has resulted in a concomitant increase in solar ... -
Using a pore-scale model to quantify the effect of particle re-arrangement on pore structure and hydraulic properties
(Wiley http://www.interscience.doi.wiley.com/10.1002/hyp.6299, 2008)A pore-scale model based on measured particle size distributions has been used to quantify the changes in pore space geometry of packed soil columns resulting from a dilution in electrolyte concentration from 500 to 1 ... -
Investigating evidence for UV-B induced mutagenesis in dimorphotheca sinuata using the 18S rDNA and rbcL gene sequences
(American-Eurasian Network for Scientific Information. http://www.aensi.org/aeb_online.html, 2008)The nuclear 18S rDNA and chloroplast encoded rbcL gene sequences were used to investigate the evidence of residual UV-B induced mutagenesis in Dimorphotheca sinuata plants. The probes were generated by the polymerase chain ... -
