cocaine abuse

in DSM–IV–TR, a pattern of cocaine use marked by recurrent significant adverse consequences related to the repeated ingestion of the substance. This diagnosis is preempted by the diagnosis of cocaine dependence: If the criteria for cocaine abuse and cocaine dependence are both met, only the latter diagnosis is given. In DSM–5, however, both have been combined into one category, stimulant use disorder, and are no longer considered distinct diagnoses. See also substance abuse.

Doppler effect

Doppler effect

the apparent increase or decrease in wavelength or frequency observed when a source of electromagnetic radiation or sound approaches or recedes from the observer or listener, producing a change in hue or pitch. The total Doppler effect may result from motion of the source, observer, or medium (such as a sound wave). [Christian Andreas Doppler (1803–1853), Austrian mathematician]
