Transition
Definition:
(n.) Passage from one place or state to another; charge; as, the transition of the weather from hot to cold.
(n.) A direct or indirect passing from one key to another; a modulation.
(n.) A passing from one subject to another.
(n.) Change from one form to another.
Example Sentences:

(5) Each profile is described by a simple sequence of band transitions (BT-sequence).
(6) These two types of transfer functions are appropriate to explain the transition to anaerobic metabolism (anaerobic threshold), with a hyperbolic transfer characteristic representing a graded transition; and a sigmoid transfer characteristic representing an abrupt transition.
(7) In addition to the phase diagrams reported here for these two binary mixtures, a brief theoretical discussion is given of other possible phase diagrams that may be appropriate to other lipid mixtures with particular consideration given to the problem of crystalline phases of different structures and the possible occurrence of second-order phase transitions in these mixtures.
