QUES: A major turning point in the development of DC machines took place in 1864, when Antonio Pacinotti described for the first time the ring armature with its symmetrically grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the invention by Zenobe Gramme who, in 1871, reinvented Pacinotti's design. In 1873, Gramme showed that his dynamo could be used as a motor, which he demonstrated to great effect at exhibitions in Vienna and Philadelphia by connecting two such DC motors at a distance of up to 2 km away from each other, one as a generator. (See also 1873 : l'experience decisive [Decisive Workaround] .)

Besides a motor, what didn't Gramme use the other device for?

QUES: Public bus services within the city are provided by the national bus operator Bus Eireann. City routes are numbered from 201 through to 219 and connect the city centre to the principal suburbs, colleges, shopping centres and places of interest. Two of these bus routes provide orbital services across the Northern and Southern districts of the city respectively. Buses to the outer suburbs, such as Ballincollig, Glanmire, Midleton and Carrigaline are provided from the city's bus terminal at Parnell Place in the city centre. Suburban services also include shuttles to Cork Airport, and a park and ride facility in the south suburbs only.

What do shuttles provide to Glanmire?

QUES: Nuclear claims between the U.S. and the Marshall Islands are ongoing, and health effects from these nuclear tests linger. Project 4.1 was a medical study conducted by the United States of those residents of the Bikini Atoll exposed to radioactive fallout. From 1956 to August 1998, at least $759 million was paid to the Marshallese Islanders in compensation for their exposure to U.S. nuclear weapon testing.

In millions of dollars, how much money did the United States pay out in nuclear testing compensation to Marshall Island residents between 1956 and 1998?
