The pulse wave is a physiological phenomenon, observable and measurable in the arterial system during blood circulation. During one heart systole a certain blood volume is expelled.ulse wave velocity analysis is a classic index of aortic stiffness and is a predictor of cardiovascular mortality in hypertensive cases. Since aortic pulse wave velocity is dominantly influenced by age, this finding may be of major importance for the evaluation of cardiovascular risk in the elderly.

Chain gang. A chain gang is a group of prisoners chained together to perform menial or physically challenging work as a form of punishment. Such punishment might include repairing buildings, building roads, or clearing land. This system existed primarily in the Southern United States, and by 1955 had been phased out nationwide, with Georgia the last state to abandon the practice. Chain gangs were reintroduced by a few states during the get tough on crime 1990s, with Alabama being the first state to revive them in 1995. The experiment ended after about one year in all states except Arizona, where in Maricopa County inmates can still volunteer for a chain gang to earn credit toward a high school diploma or avoid disciplinary lockdowns for rule infractions.
