(Portland International Center for Management of Engineering and Tecnology (PICMET) Conference 2008, 2008-07)In investigating the link between R&D and innovation, data was used from the South African Innovation Survey of 2001 (SAIS2001). The SAIS2001 results showed that South African enterprises had a relatively high level of ...
-
(Trans Tech Publications, 2013)The history of semi-solid metal forming and in particular rheo-high pressure die casting at the Council for Scientific and Industrial Research in South Africa is discussed. Processing flexibility is demonstrated on the ...
-
(Trans Tech Publications, 2013)Flexibility of the Council for Scientific and Industrial Research’s Rheocasting System (CSIR-RCS) and its rheo-high pressure die casting (R-HPDC) technology is again demonstrated, as with aluminium alloys, by processing ...
-
(Palgrave Macmillan, 2010-05)This chapter begins with a brief tour of South Africa's justice and political systems, demographics and discourses of race. The brief narrative, which will also allude to situations in Apartheid South Africa, is meant to ...
-
(CSIR, 2008-11)South Africa, like other countries, faces the challenge of protecting its territory and its people from activities such as illegal border crossings, weapons trafficking, smuggling, piracy, poaching, organised crime, and ...
-
(Institute of Electrical and Electronic Engineering (IEEE), 2009-07)This paper presents a classification method which discriminates between two radar transmitters based on the received pulses. A simple radar transmitter model is presented to which a non-stationary signal classifier is ...
-
(American Physical Society, 2014)The radial degrees of freedom of the biphoton states that are produced in spontaneous parametric down-conversion (SPDC) in the Laguerre-Gaussian (LG) basis are investigated, theoretically and experimentally. We calculated ...
-
(SPIE, 2017-08)Beams carrying orbital angular momentum (OAM) are ubiquitous in many experiments carried out today and cover a wide range of research, from surface microstructure processing to optical tweezers and communications. It follows ...
-
(IEEE Institute of Electrical and Electronics, 2006-12)Laser-induced breakdown spectroscopy (LIBS) is a non-intrusive technique that needs no sample preparation and even recently, quantitative measurements were done without the need for calibration standards. Much research has ...
-
(Zoological Society of Southern Africa, 2005-10)Irradiation has adverse effects on reproductive aspects such as spermatogenic cell population and cell malformation, leading to reduced sperm count and non-viable spermatozoa. This has overshadowed possible effects of ...
-
(CSIR, 2013)This report forms a summary of the work done by the Chamber of Mines Research Organization before it merged with the CSIR. It deals with gold mining in South Africa, and contains a summary of the work that was done on ...
-
(Pergamon-Elsevier Science Ltd, 2002-01)South Africa's national radioactivity measurement standard is maintained at a satellite laboratory in Cape Town by the National Metrology Laboratory (NML) of the Council-for Scientific and Industrial Research. Standardizations ...
-
(Bureau Scientific Publisher, 2001-03)High-precision radiocarbon dating of a millennium-old yellowwood tree from the Midlands of Natal shows that the tree-rings do, in general, record annual growth, but that both missing and false rings occur. At two places ...
-
(Bureau Scientific Publications, 1992-11)There are several problems associated with determining radiocarbon dates, particularly for organic material from Antarctica. However, this study attempts to find accurate measure of the length of time these radiocarbon ...
-
(Bureau Scientific Publications, 1996-01)The age of the peat, or 'lignite', layer in the Port Durnford Formation on the Zululand coast has been established to be about 70 kyr by means of the Th-230/U-234 disequilibrium dating technique. This date places the pent ...
-
(2019-12)Ultrasonic guided waves have been shown to propagate large distances in continuously welded rail track.
-
(Blackwell Science Ltd, 1999-03)Woody community phenology was studied in the central lowveld, South Africa, over a twelve month period at three sites along a rainfall gradient, with both toplands and bottomlands sampled at each site. Each month, individual ...
-
(Pergamon-Elsevier Science Ltd, 2003-04)The aim in this paper is threefold: firstly to gain an initial understanding of rainwater chemistry in the northeast of Uruguay; secondly to identify possible sources that contribute to its chemical composition; and thirdly ...
-
(2010-02-15)The report highlights the different methods of collecting and storing rainwater before it enters the soil or flows into the streams. Some of the methods described are intercepting the rainfall, landscapes and treatment of ...
-
(IIED & CSIR, 2001-10)This report is about the changes taking place in South African forestry, the pros and cons of these changes and the prospects for a forest sector that can contribute to sustainable national development and local empowerment. ...
