Aswan (horse) Aswan (horse) Aswan (1958–1984), originally named Raafat in Egypt. Aswan was a highly influential grey Egyptian-bred Arabian stallion who stood at the Tersk Stud in Russia. Sired by Nazeer out of Yosreia, he was given as a gift to the Soviet Union by the Egyptian government in 1963, in return for Soviet help in building the Aswan Dam. He sired 296 foals over 19 seasons, more than any other stallion at Tersk Stud. His offspring were exported all over the world. A life-size commemorative bronze statue of him stands at the entrance to the Tersk Stud. Though classified as "Straight
Hydropower policy in the United States of 90% efficiency. More importantly, Francis's mathematical and graphical calculation methods advanced turbine design and engineering and allowed confident design of high efficiency turbines to exactly match a site's flow conditions. In the 1870s and deriving from uses in the mining industry, the high efficiency Pelton wheel impulse turbine was developed to use hydropower under very different flow and pressure conditions. Advances in dam design also progressed, with the completion of Old Aswan Dam being considered a milestone of engineering over nature. At the time of its construction, nothing of such scale had ever been attempted: it also became one
