First Sesotho soundtrack for fulldome film launched at Naval Hill Planetarium

In December, the Naval Hill Planetarium used the voice of a well-known South African actress for yet another trailblazer: the first Sesotho soundtrack for a full-dome film.

“It is important for our children to become interested in science and astronomy through exposure to good language use in their mother tongue from an early age, so that we can still make a sound contribution to these fields in the future,” said Prof Matie Hoffman from the Department of Physics at the University of the Free State.

Space Shapes, a child-friendly fulldome film by the Ott Planetarium at the Weber State University in Utah in the US, was translated into Sesotho as Dibopeho tsa Sepakapakeng by Khantlapane Selina Ketla and Dr Andries Hoffman, following last year’s release of the short film by the Naval Hill Planetarium as Ruimtevorms in Afrikaans. The film, created by participants of the 2010 Blender Production Workshop in Utah, takes young audiences on a journey to explore the different shapes found in space.

The voice artist, Tshireletso Nkoane, a star in her own right, is best-known for her television roles in the drama series, Tshisa, the comedy series, Moferefere Lenyalong, as well as the miniseries, Naledi. She has several theatre and radio credits to her name, and also boasts a diploma in Electrical Engineering.

The premiere of this Sesotho trailblazer, as well as the CosmoQuest and Ward Beecher Planetarium’s English fulldome film, Cosmic Castaways, will take place at the Naval Hill Planetarium on Saturday 17 February 2018 at 17:30. Cosmic Castaways is an exciting work that reaches out to places where there are no constellations; where there are still isolated stars to be found in the voids between the galaxies.

Tickets for this double premiere, as well as for the weekly Saturday 17:30 shows, are available from Computicket – just search under ‘planetarium’ on the Computicket website or visit Checkers.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
