Because of the difficulty of moving crude bitumen through pipelines, non-upgraded bitumen is usually diluted with natural-gas condensate in a form called dilbit or with synthetic crude oil, called synbit. However, to meet international competition, much non-upgraded bitumen is now sold as a blend of multiple grades of bitumen, conventional crude oil, synthetic crude oil, and condensate in a standardized benchmark product such as Western Canadian Select. This sour, heavy crude oil blend is designed to have uniform refining characteristics to compete with internationally marketed heavy oils such as Mexican Mayan or Arabian Dubai Crude.
What is the synthetic crude additive to bitumen called?
synbit

Reservations are essentially caveats to a state's acceptance of a treaty. Reservations are unilateral statements purporting to exclude or to modify the legal obligation and its effects on the reserving state. These must be included at the time of signing or ratification, i.e. "a party cannot add a reservation after it has already joined a treaty".

Hospital Maciel is one of the oldest hospitals in Uruguay and stands on the block bounded by the streets Maciel, 25 de Mayo, Guaraní and Washington, with the main entrance at 25 de Mayo, 172. The land was originally donated in Spanish colonial times by philanthropist Francisco Antonio Maciel, who teamed up with Mateo Vidal to establish a hospital and charity. The first building was constructed between 1781 and 1788 and later expanded upon. The present building stems from the 1825 plans of José Toribio (son of Tomás Toribio) and later Bernardo Poncini (wing on the Guaraní street, 1859), Eduardo Canstatt (corner of Guaraní and 25 de Mayo) and Julián Masquelez (1889). The hospital has a chapel built in Greek style by Miguel Estévez in 1798.
When was the first building of the Hospital Maciel established?
between 1781 and 1788
