ISG’s Sarah Frank researches impact of historic conflicts on society
Dr Sarah Frank, postdoctoral researcher at the ISG.

History has an interesting connection with society, as we all grow up learning about our country’s history and studying it at school. However, what we learn at school is often a glorified version of events. It can sometimes be challenging for historians to come to grips with the most accurate version of a particular ‘history’. 

Dr Sarah Frank is a postdoctoral research fellow with the International Studies Group (ISG), who fell in love with history at a young age. She says, "I was very lucky to have outstanding history teachers at school who fostered my interest and curiosity." Early on, though, she experienced disappointment. "In school, there was a series of biographies of American leaders and presidents written for children. I remember feeling betrayed when I subsequently learnt that the biographies had not presented a well-balanced narrative. That is when I learnt that history could be debated and interpreted—and it is full of nuances."

Interested in conflict shaping lives

Dr Frank was particularly intrigued by the social and political history of the Second World War (WWII). She describes her interest in this way: "The Second World War looms in popular memory as much as in the historical one. I am interested in how conflict shaped people’s lives during and after the war." Being a speaker of French helped her to focus on the impact of the war on France, and having spent a few years living in West Africa, confronted with the lingering colonial past, she decided to home in on the French empire, with particular attention to colonies, captivity, and the repercussions of war experiences when soldiers returned home. Additionally, she explores the themes of decolonisation, the roots of independence movements, and the lingering ties between the former imperial powers and former colonies.

Although she grew up near Boston, Massachusetts, studied for her master's in Dublin, and has lived in far-flung places such as Guinea (while serving with the Peace Corps) and Dakar, Dr Frank says, "I have lived in a lot of places, but Bloemfontein is definitely one of my favourites!"

Colonial POWs her new focus

Currently, Dr Frank is writing a book based on her PhD research, which delved into the experiences of approximately 85 000 soldiers in captivity from across the French Empire, who fought in France from 1939-1940. The Germans decided to racially separate the colonial prisoners of war (CPOWs), taking white prisoners to Germany and leaving the colonial prisoners in camps across occupied France. This created opportunities for colonial prisoners to interact with the French civilians, something which rarely occurred in the strict hierarchical colonial regime. Perhaps surprisingly, considering the racism of both the French and German regimes, Colonial prisoners fared better in captivity in France than their French counterparts did in Germany.

Dr Frank's next project will trace the return of the African soldiers who fought during the Second World War. She seeks to understand what happened to them as well as their families when they returned, and to see if their experience actually impacted the growing independence movements which arose following 
WWII.

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.
