Abstract: An electronic device responds to a user input that includes a movement detected while displaying a user interface object at a first position relative to a first user interface of a first application. If the user input is directed to a location that corresponds to the first user interface object at a start of the movement, the electronic device moves a respective representation of the first user interface in accordance with the movement, relative to a background located behind the first user interface and remaining visible during the movement. If the user input is directed to a portion of the first user interface that is away from the location that corresponds the first user interface object, at the start of the movement, the electronic device performs an operation within the first user interface without moving the respective representation of the first user interface relative to the background.

Abstract: A method for the production of cast nodular or ductile iron wherein molten iron having been first contacted with a graphite-spheroidizing agent is after-treated with an alloy consisting essentially of silicon, calcium, magnesium, aluminum, cerium, barium, and iron so as to reduce the formation of iron carbides or chill in the resulting cast nodular iron.
