Ancient Carthage the site of the city. Nearly all of the other Phoenician city-states and former Carthaginian dependencies subsequently fell into Roman hands. According to Roman sources, Phoenician colonists from modern-day Lebanon, led by Dido (also known as Queen Elissa), founded Carthage "circa" 814 BC. Queen Elissa (also known as "Alissar") was an exiled princess of the ancient Phoenician city of Tyre. At its peak, the metropolis she founded, Carthage, came to be called the "shining city", ruling 300 other cities around the western Mediterranean Sea and leading the Phoenician world. Elissa's brother, Pygmalion of Tyre, had murdered Elissa's husband, the high
DIDO (nuclear reactor) DIDO (nuclear reactor) DIDO was a materials testing nuclear reactor at the Atomic Energy Research Establishment at Harwell, Oxfordshire in the United Kingdom. It used enriched uranium metal fuel, and heavy water as both neutron moderator and primary coolant. There was also a graphite neutron reflector surrounding the core. In the design phase, DIDO was known as AE334 after its engineering design number. DIDO was designed to have a high neutron flux, largely to reduce the time required for testing of materials intended for use in nuclear power reactors. This also allowed for the production of intense beams of neutrons
