API Gravity: An arbitrary scale expressing the gravity or density of liquid petroleum products. The measuring scale is calibrated in terms of degrees API; it is calculated as follows: Degrees API = (141.5 / (sp. gr. 60ÂºF / 60ÂºF)) - 131.5 The higher the API gravity, the lighter the compound.
| Filed Under: Firsts 1 Comment. The now famous character Mario was created by Shigeru Miyamoto and has appeared in over 200 video games. Marioâs first appearance was in Donkey Kong (ãã³ã­ã¼ã³ã³ã°) in 1981, which is another iconic arcade game developed by Nintendo. In Donkey Kong, Mario was known as âJumpmanâ the carpenter. In later games, Mario is depicted as a short Italian plumber.
Mario first appeared in the arcade Mario Bros where he cleaned pipes from crabs, koopas, and other goons. This was also a mini-game in Super Mario Bros 3. Although he is featuâ¦red in Donkey Kong for NES, in the original Donkey Kong arcade cabinet the hero was named Jump Man. The change to Mario on the NES version was made to sell units based on recognition. Super Mario Bros uses a very similar design and physics to the original Mario Bros so that may be why Nintendo stuck with pipe/plumber theme.
