Author:Bischof-Niemz, TDate:Sep 2015This presentation looks at the status of the South African energy industry today. Solar PV & wind are the cheapest new-build options per kWh in South Africa, and cost competitiveness of renewables has two consequences: 1) distributed power ...Read more
Author:Johakimu, Jonas K; Bush, T; Lucia, LDate:Feb 2011The effect of green liquor pre-treatment (GLP) on Kraft pulping of Pinus Patula has been investigated. Wood chips were pre-treated with green liquor, and subsequently subjected to Kraft pulping to achieve a target Kappa number of 65-70. The ...Read more
Author:Van Wyk, Llewellyn VDate:Apr 2010Green roofs are roofs that have been covered with a growing medium, creating a habitat on what would otherwise be a bland, lifeless surface. It is for this reason that green roofs are sometimes call 'vegetated' or 'living' roofs (Cantor 2008). ...Read more
Author:Schoeman, C; Sanchez, VRDate:Jul 2009This paper investigates status quo concerning the environment and the human (economic) impact on its sustainability. It narrows in on the South Africa context and then focuses on the transport and supply chain's contributions. Green supply ...Read more
Author:Ittmann, HDate:Jan 2011This article is not a comprehensive overview of green logistics. What it endeavours to do is to sensitise, in a very summarised way, those involved in logistics and supply chain management about the importance of green logistics and to highlight ...Read more
Author:Van Wyk, Llewellyn VDate:Mar 2014Green infrastructure can be defined as the design and development of infrastructure that works with natural systems in the performance of its functions. Green infrastructure recognises the importance of the natural environment in land use ...Read more
Author:Scholes, RJ; Van der Merwe, Martina RDate:May 1996South African greenhouse gas emissions contributed about 1.2% to the global increase in the greenhouse effect in 1988. South Africa generated trace gases with a radiation absorption potential over a 20-year period equivalent to 534 million ...Read more
Author:Jagarnath, M; Thambiran, TirushaDate:Aug 2017Because current emissions accounting approaches focus on an entire city, cities are often considered to be large emitters of greenhouse gas (GHG) emissions, with no attention to the variation within them. This makes it more difficult to ...Read more
Author:Nickless, A; Ziehn, T; Rayner, PJ; Scholes, RJ; Engelbrecht, FDate:May 2014This is the second part of a two-part paper considering network design based on a Lagrangian stochastic particle dispersion model (LPDM), aimed at reducing the uncertainty of the flux estimates achievable for the region of interest by the ...Read more
Author:Ziehn, T; Nickless, A; Rayner, PJ; Law, RM; Roff, G; Fraser, PDate:Sep 2014This paper describes the generation of optimal atmospheric measurement networks for determining carbon dioxide fluxes over Australia using inverse methods. A Lagrangian particle dispersion model is used in reverse mode together with a Bayesian ...Read more
Author:Van Wyk, Llewellyn VDate:Oct 2014The development and maintenance of infrastructure is crucial to improving economic growth and quality of life (WEF 2013). Urban infrastructure typically includes bulk services such as water, sanitation and energy (typically electricity and ...Read more
Author:Godfrey, Linda KDate:Nov 2014The Waste Sector, as with many sectors of the economy, is responding to the call to transition to a Green Economy. Globally, waste management is changing from one of ‘collect-transport-dispose’, to one of ‘secondary resource management’, ...Read more
Author:Jamison, Kevin ADate:Sep 2018The analysis of the separation of a Precision Guided Munition (PGM) from many configurations of an advanced jet trainer was performed using aerodynamic data from wind-tunnel tests characterised using the grid method. As strong aerodynamic ...Read more

The price of PV has been going down in ...Read more
Author:Estuarine and Coastal Research Unit, ECRUDate:Jun 1981The state of knowledge of the Groen is poor. The area, being remote, has received little attention in the past and the bulk of information in this report originates from the Estuarine and Coastal Research Unit (ECRU) survey. Although the Groen ...Read more
Author:Harmse, M; Von, HJDate:Sep 1977The soils of the Nylsvley Nature Reserve are classified according to the binomial system and mapped on a scale of 1:5 000. 17 soil forms and 34 soil series are described. The main soil forms within the Savanna Ecosystem Project study area ...Read more
Author:Morant, PD; Bickerton, IBDate:Jun 1983Little is known of the early history of the area surrounding the Groot and Sout estuaries. The densely forested terrain dissected by deep gorges caused the area to be avoided by early travellers who used the inland route via the Langkloof to ...Read more
Author:Morant, PDDate:Dec 1983The Great Brak estuary has been endowed with great scenic beauty and recreational potential. The estuary and environs thus offer a great challenge for progressive development with the needs of existing industries and residential areas having ...Read more
