Problem: Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.
 How can't a hysteresis synchronous motor's rotor be described?

Problem: Since Elizabeth rarely gives interviews, little is known of her personal feelings. As a constitutional monarch, she has not expressed her own political opinions in a public forum. She does have a deep sense of religious and civic duty, and takes her coronation oath seriously. Aside from her official religious role as Supreme Governor of the established Church of England, she is personally a member of that church and the national Church of Scotland. She has demonstrated support for inter-faith relations and has met with leaders of other churches and religions, including five popes: Pius XII, John XXIII, John Paul II, Benedict XVI and Francis. A personal note about her faith often features in her annual Christmas message broadcast to the Commonwealth. In 2000, she spoke about the theological significance of the millennium marking the 2000th anniversary of the birth of Jesus:
Beyond Christianity what leaders of other religions has Elizabeth met with?

Problem: The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.
Where can the remnants of Yaghnobi be found?

Zarafshan valley
