From 2007 to 2014, the country experienced an exponential rise in rhino poaching – a growth of over 9,000%. Most illegal activities occur in the Kruger National Park.

 

Contributing to fight this battle is a group of five former students and colleagues from the UFS Department of Chemistry, now in the employment of Wildlife Pharmaceuticals. Situated in the Nelspruit area, Dr Inus Janse van Rensburg, Head of Research and Development; Lizette Janse van Rensburg, Head of Operations; Leo Kirsten, API expert; Dr Rikus Peens, API chemist; and Dr Chris Joubert, Laboratory Specialist, are working at this pharmaceutical manufacturing facility. The company specialises in the development, manufacturing, and end use of wildlife medicines.

 

With the medicines they develop, they are able to immobilise animals. Prof André Roodt, Discipline Head of the UFS Division of Inorganic Chemistry, who attended Indaba 9 with members of his research team in Skukuza, Kruger National Park, said wildlife species are being chemically immobilised for different reasons.

 

Prosecution of poachers

 

One example is of a rhino which was immobilised after a successful dehorning procedure by veterinarians and personnel of Wildlife Pharmaceuticals. As part of a programme to discourage poaching, selective DNA data collection is also conducted by some veterinarian groups for future use in the possible prosecution of individuals who are dealing with rhino horn. As soon as a rhino that was killed during poaching has been discovered, samples of the animal are obtained for a full analysis.

 

These samples are then stored on a database. Wherever rhino horn is confiscated (even internationally), the DNA is analysed, and the database may be consulted to see where the specific rhino was killed. The person in possession of the rhino horn may then be charged with the ‘killing’ of the original rhino.

 

Prof Roodt explained that the foundation of all medicines is based on active pharmaceutical ingredients (APIs) present in the finished pharmaceutical product, be it tablets, capsules, a syrup or a sterile injectable liquid. In accordance with local and international regulations and guidelines, chemists at API facilities are manufacturing these APIs globally.

 

Wildlife conservation

 

The APIs are respectively incorporated into registered finished pharmaceutical products, which are then used by registered veterinarians for chemical immobilisation and reversal of immobilisation in wildlife species.

 

According to Prof Roodt, the importance of developing appropriate chemical agents and the role of chemical manufacturing are crucial for animal conservation, with a scope far beyond the field of animal immobilisation, thus extending it to animal health, treatments, and vaccinations.

 

Besides saving our rhinos, wildlife species require immobilisation for different reasons. This can include, for example, wound treatment, relocation, and surgical procedures. “It is critical that the animals be immobilised to ensure limitation of stress to the animal, mitigate self-harm, allow safe handling of the animal, and for operator safety. These activities will be impossible to execute without chemical immobilisation of the animal,” said Prof Roodt.

 

Dr Janse van Rensburg, who received his PhD in the UFS Department of Chemistry in 2008, said the department, through exposing its students to, among others, complex equipment in labs as well as work in international labs to critically assess and benchmark their work against others, contributed to the success of his career at Wildlife Pharmaceuticals.

Africa the birthplace of mathematics, says Prof Atangana

Prof Abdon Atangana from the Institute for Groundwater Studies at the University of the Free State recently received the African Award of Applied Mathematics during the International conference "African’s Days of Applied Mathematics" that was held in Errachidia, Morocco. Prof Atangana delivered the opening speech with the title "Africa was a temple of knowledge before: What happened?” The focus of the conference was to offer a forum for the promotion of mathematics and its applications in African countries.

When Europeans first came to Africa, they considered the architecture to be disorganised and thus primitive. It never occurred to them that Africans might have been using a form of mathematics that they hadn’t even discovered yet.

Africa is home to the world’s earliest known use of measuring and calculation. Thousands of years ago Africans were using numerals, algebra and geometry in daily life. “Our continent is the birthplace of both basic and advanced mathematics,” said Prof Atangana. 

Africa attracted a series of immigrants who spread knowledge from this continent to the rest of the world.

Measuring and counting
In one of his examples of African mathematics knowledge Prof Atangana referred to the oldest mathematical instrument as the Lebombo bone, a baboon fibula used as a measuring instrument, which was named after the Lebombo Mountains of Swaziland. The world’s oldest evidence of advanced mathematics was also a baboon fibula that was discovered in present-day Democratic Republic of Congo.

Another example he used is the manuscripts in the libraries of the Sankoré University, one of the world’s oldest tertiary institutions. This university in Timbuktu, Mali, is full of manuscripts mainly written in Ajami in the 1200s AD. “When Europeans and Western Asians began visiting and colonising Mali between the 1300s and 1800s, Malians hid the manuscripts in basements, attics and underground, fearing destruction or theft by foreigners. This was certainly a good idea, given the Europeans' history of destroying texts in Kemet and other areas of the continent. Many of the scripts were mathematical and astronomical in nature. In recent years, as many as 700 000 scripts have been rediscovered and attest to the continuous knowledge of advanced mathematics and science in Africa well before European colonisation. 

Fractal geometry

“One of Africa’s major achievements was the advanced knowledge of fractal geometry. This knowledge is found in a wide aspect of Africa life: from art, social design structures, architecture, to games, trade and divination systems. 

“The binary numeral system was also widely known through Africa before it was known throughout much of the world. There is a theory that it could have influenced Western geometry, which led to the development of digital computers,” he said. 

“Can Africa rise again?” Prof Atangana believes it can.

He concluded with a plea to fellow African researchers to do research that will build towards a new Africa.
