Duck
a batsmans score of nought (zero) dismissed, as in "he was out for a duck." It can refer to a score of nought not out during an innings, as in "she hasnt got off her duck yet", but never refers to a completed innings score of nought not out. Originally called a "ducks egg" because of the "0" shape in the scorebook. ( see Golden, Diamond, and Platinum duck )

Duck under delivery
a short pitched delivery that appears to be a bouncer, making the striker duck to avoid from being hit; but instead of bouncing high, it has a low bounce which causes the batsman to be dismissed LBW, or occasionally bowled. Duckworth-Lewis method (D/L)
(or Duckworth-Lewis-Stern method, DLS)
a rain rule used if a limited overs match is curtailed by bad weather. If the match cannot be completed, the Duckworth-Lewis method determines the winner, or if the match can be continued but needs to be shortened, it calculates a revised target for the team batting second.
The idea was based on an experience in World War I in which two soldiers presented to him with broken femurs after having lain on the ground for seven days without food and water. Baer could not figure out why neither man had a fever or signs of sepsis. He observed: "On removing the clothing from the wounded part, much was my surprise to see the wound filled with thousands and thousands of maggots, apparently those of the blow fly. The sight was very disgusting and measures were taken hurriedly to wash out these abominable looking creatures." However, he then saw that the wounds were filled with "beautiful pink granulation tissue" and were healing well.Maggot therapy was common in the United States during the 1930s. However, during the second half of the twentieth century, after the introduction of antibiotics, maggot therapy was used only as a last resort for very serious wounds. Lately maggots have been making a comeback due to the increased resistance of bacteria to antibiotics. References
