Description: Tebello Nyokong speaks to Robert Berold and Janice Limson about her career as a chemist. Tebello Nyokong, who holds a research chair in medicinal chemistry and nanotechnology at Rhodes University, has become the first South African scientist to win the L’Oreal-UNESCO award for women in science, in the physical sciences. Only one laureate is selected from each of five world regions, and Nyokong is the 2009 laureate for Africa and the Arab states. She and the winners from the other four regions travel to Paris in March to each accept the award and a generous prize of close to R1 million. Nyokong now heads the new Nanotechnology Innovation Centre for medical sensors: the biggest single research investment in the history of Rhodes. Linked to other nanotechnology centres in the country, it is designed to bridge the gap between research and the market.

Description: As demand for new, reliable, flexible and relatively inexpensive internet access in marginalized rural areas in developing countries increases, there is a need to amalgamate broadband technologies such as WiMAX and WiFi so as to extend the coverage area. Consequently, this will en-able provision of high-speed mobile data and telecommunications ser-vices. This paper describes how WiMAX and WiFi can be merged to-gether, with VSAT technology offering backhaul internet connectivity to provide ever present broadband access. We also look at their respective network applications and how there are going to be used to help support ICT4D activities in these marginalized areas.

In 1990, with the strong support of the incumbent Vice-Chancellor, Dr Derek Henderson, he instigated the Certificate in Change Ringing (Church Bell Ringing) in the Rhodes University Department of Music and Musicology - the first such course to be offered in Africa. Since that date he has lectured in the basic theory, and taught the practice of change ringing. He is the Ringing Master of the Cathedral of St Michael and St George, Grahamstown, South Africa.

Description: Photographic souvenir books of towns and cities around the world were very popular during the late 19th and early 20th centuries. These vol-umes, printed to a high standard and bound in a superior quality bind-ing, showed off commercial and civic buildings, churches, schools and views of the surrounding natural environment. Grocott and Sherry, a firm of Grahamstown printers and publishers, published a number of these souvenirs of Grahamstown, the last one appearing in 1898. Earli-er this year an exhibition was mounted in Grahamstown's Albany Mu-seum to celebrate 140 years since the founding of the Grocott's Mail, a newspaper published until 2003 by the firm of Grocott and Sherry and since then owned and operated by the Rhodes University School of Journalism and Media Studies.

Description: The introduction of network filters and chokes such as firewalls in exist-ing operational network is often problematic, due to considerations that need to be made to minimise the interruption of existent legitimate traf-fic. This often necessitates the time consuming manual analysis of net-work traffic over a period of time in order to generate and vet the rule bases to minimise disruption of legitimate flows. To improve upon this, a system facilitating network traffic analysis and firewall rule set genera-tion is proposed. The system shall be capable to deal with the ever in-creasing traffic volumes and help to provide and maintain high uptimes. A high level overview of the design of the components is presented. Additions to the system are scoring metrics which may assist the admin-istrator to optimise the rule sets for the most efficient matching of flows, based on traffic volume, frequency or packet count. A third party pack-age-Firewall Builder-is used to target the resultant rule sets to a number of different firewall and network Filtering platforms.

Plants for health, life and spirit in Africa : implications for biodiversity and cultural diversity conservation

Description: [From Introduction] Natural resources are often only perceived as contributing to rural livelihoods through food production and household welfare. There is a growing wealth of information capturing the direct-use values of the environment and consequent recognition of natural resources as being “the poor man's overcoat”. These approaches, however, have failed to fully account for the various ways in which different groups of people make use of, and find value in biodiversity. New developments within the field of anthropology have begun to explore the relationship between biodiversity and human diversity. This view has largely come about because many of the areas of highest biological diversity are inhabited by indigenous and traditional people, providing what the Declaration of Belem (1988) calls an 'inextricable link' between biological and cultural diversity (Posey 1999). The term bio-cultural diversity was introduced by Posey in 1999 to describe the concept denoting this link. , Funding was received from the South Africa-Netherlands Programme on Alternatives in Development (SANPAD) and the International Foundation of Science (IFS)
