Problem: Mali:

On 19 November 1968, following progressive economic decline, the Keita regime was overthrown in a bloodless military coup led by Moussa Traore, a day which is now commemorated as Liberation Day. The subsequent military-led regime, with Traore as president, attempted to reform the economy. His efforts were frustrated by political turmoil and a devastating drought between 1968 to 1974, in which famine killed thousands of people. The Traore regime faced student unrest beginning in the late 1970s and three coup attempts. The Traore regime repressed all dissenters until the late 1980s.

Due to the variety of constructions now available, the technology is used in applications from high temperature military to low cost pump and basic servos.
