(Academy of Science of South Africa, 2007-03)With the advent of ever faster computers, the operational use of nonhydrostatic atmospheric models at resolutions beyond the hydrostatic limit has become a reality. A renewed global research effort is being made to formulate ...
-
(Agricultural Research Council, ARC-OVI and the University of Pretoria, 2007-03)The suitability of present and future climates for 30 Rhipicephalus species in Africa are predicted using a simple climate envelope model as well as a Division of Atmospheric Research Limited-Area Model (DARLAM). DARLAM's ...
-
(Elsevier, 2007-04-15)The steady-state surface compositions of the polar (O and Zn terminated) faces of ZnO{0 0 0 1} produced by low energy (0.3–2 keV) Ar+ ion bombardment were studied by Auger electron spectroscopy and electron energy loss ...
-
(Academy of Science of South Africa, 2007-07)Loss of topsoil is one of the principal soil degradation problems confronting agriculture throughout South Africa and receives special attention by policy-makers. For effective prevention and remediation, the spatial extent ...
-
(Wiley, 2007-08)Fog that reduces visibility to the point where aircraft have to divert to another airport is not uncommon at Abu Dhabi International Airport (ADIA) in the United Arab Emirates (UAE). Over the period 1982 to 2003, ...
-
(Academy of Science of South Africa, 2007-09)The heritage of San rock art in southern Africa is globally acknowledged, and was one of the primary reasons for the successful nomination of the uKhahlamba / Drakensberg Park in South Africa as a World Heritage Site. ...
-
(Academy of Science of South Africa, 2007-09)Rainfall intensity, kinetic energy and erosivity were analysed for 106 erosive storm events at five locations in the KwaZulu-Natal Drakensberg, from late 2001 to early in 2006. The stations cover an altitudinal range of ...
-
(Wiley, 2007-12)Estimates have been made that, annually, up to about two billion tons of dust are carried up into the atmosphere, mainly by dust storms. One dust storm can lift and deposit more than 200 tons of dust (Griffin et ...
-
(CRIMSA, 2008)South Africa is a country ravaged by crime, yet few theoretical frameworks exist by which to guide crime reduction initiatives, and none incorporating a spatial component. Crime scientists are becoming increasingly aware ...
-
(Society of South African Geographers, 2008)The aim of this paper is to improve knowledge on the spatial origin and development of criminal offenders within the Tshwane municipality. A preliminary socio-demographic profile of offenders residing within Tshwane is ...

(Blackwell, 2008)Located near the south-eastern limit of Africa, the Lesotho–Drakensberg and associated escarpment is the highest range of African mountains south of the massifs in Tanzania. At the escarpment summit and on the adjacent ...
-
(CRIMSA, 2008)While local researchers postulate the proximate causes of crime, few spatial-ecological studies have been used to investigate the location of offenders. In this study, for the first time in a South African context, the ...
-
(Cambridge University Press, 2009)Landforms with the appearance of cryoplanation terraces were studied on Alexander Island in an attempt to better understand their formation and growth. Developed on sub-horizontal sedimentary rocks, with 3608 exposure ...
-
(Elsevier, 2009)On sub-Antarctic Marion Island cushions of the dominant vascular plant species, Azorella selago, interact with the geomorphology of fellfield landscapes by affecting sediment distribution and ultimately terrace formation. ...
-
Rock weathering on the eastern mountains of southern Africa : review and insights from case studies (Elsevier, 2009)The mountains in the eastern region of southern Africa are of significant regional importance, providing for a diverse range of land use including conservation, tourism and subsistence agriculture. The higher regions are ...
-
(Society of South African Geographers, 2009)While concern for the conservation of cultural stone and rock art continues to grow, so the gap between knowledge of the processes causing deterioration and those assumed to be operating increases. At the same time, in ...
