Germany is a federal republic consisting of sixteen federal states (German: Bundesland, or Land).[a] Since today's Germany was formed from an earlier collection of several states, it has a federal constitution, and the constituent states retain a measure of sovereignty. With an emphasis on geographical conditions, Berlin and Hamburg are frequently called Stadtstaaten (city-states), as is the Free Hanseatic City of Bremen, which in fact includes the cities of Bremen and Bremerhaven. The remaining 13 states are called Flachenlander (literally: area states).
What are Hamburg and Berlin called?

His biography of Anthony the Great entitled Life of Antony( , Vita Antonii) became his most widely-read work. Translated into several languages, it played an important role in the spreading of the ascetic ideal in Eastern and Western Christianity. Depicting Anthony as an illiterate and holy man who through his existence in a primordial landscape has an absolute connection to the divine truth, the biography also resembles the life of his biographer Athanasius. It later served as an inspiration to Christian monastics in both the East and the West. The so-called Athanasian Creed dates from well after Athanasius's death and draws upon the phraseology of Augustine's De trinitate.
The biography, Life of Antony, also resembles of the life of who?
Athanasius

DC commutating electric motors, if fitted with laminated pole pieces, become universal motors because they can also operate on AC; reversing the current in both stator and rotor does not reverse the motor. But the now-standard AC distribution frequencies of 50 and 60 Hz caused difficulties with inductive reactance and eddy current losses. Many railways chose low AC frequencies to overcome these problems. They must be converted from utility power by motor-generators or static inverters at the feeding substations or generated at dedicated traction powerstations.
How can DC motor turn universal?
if fitted with laminated pole pieces
