rollback

The mining industry also had a hand in two other rollbacks. One was a decision to withdraw a Clinton rule that reduced by 80 percent the permissible standard for arsenic in drinking water.

During the 1990s the Pope, who played such a central role in the rollback of communism, was one of the few international figures who could be heard speaking out against the new capitalist order.

The data was examined with respect to oil pressure. This showed that both the left and right engines' oil pressure generally follow each other until the start of the final acceleration, which resulted in first the right and then the left engines rolling back. The left engine oil pressure rose, as expected, as the engine accelerated: the right engine pressure, however, started to decrease, even though the engine was also accelerating prior to its rollback. Whilst, this observation, on the right engine, was based on only a few data points, it can be inferred that this was due to an oil temperature increase at, or close to, the start of the final acceleration. However, the loss of QAR data so close to the left engine rollback meant that it was not possible to draw a similar conclusion for the left engine.
