This technique could be applied both successively and simultaneously. The invasion force was divided into three groups, which were to land successively. Ecologists usually characterize succession through the changes in vegetation that successively arise. Binary submultiples are fractional parts obtained by successively dividing by the number 2. Similarly, successively larger elements must have shells of successively higher energy. Instead, each division produces successively smaller cells. The juice was skimmed and then channeled to successively smaller kettles. Bracketing methods determine successively smaller intervals (brackets) that contain a root. Primes that remain prime when the least significant decimal digit is successively removed. Primes that remain prime when the leading decimal digit is successively removed. The virial coefficients account for interactions between successively larger groups of molecules. The most weakly charged compounds will elute first, followed by those with successively stronger charges. As the show proceeds, each one is eliminated with successively more difficult words. The biofilm creates a surface onto which successively larger microorganisms can attach. There are three levels of certification, each allowing the user to fly successively larger motors.
