Stiffness


Definition:

  • (n.) The quality or state of being stiff; as, the stiffness of cloth or of paste; stiffness of manner; stiffness of character.

Example Sentences:

  • (1) If you turn the bowl upside down, the whites should be stiff enough not to fall out.
  • (2) The stiffness of the fibre first rose abruptly in response to stretch and then started to decrease linearly while the stretch went on; after the completion of stretch the stiffness decreased towards a steady value which was equal to that during the isometric tetanus at the same sarcomere length, indicating that the enhancement of isometric force is associated with decreased stiffness.
  • (3) Current methodology for the in vitro determination of aortic and large artery stiffness is reviewed and involves three approaches: (1) the estimation of distensibility by pulse wave velocity measurement; (2) the estimation of distensibility from the fractional diameter change of a given arterial segment by imaging techniques (e.g., angiography, Doppler ultrasound) against pressure change; (3) the estimation of compliance by determining volume change against pressure change in the arterial system during diastolic runoff from the Windkessel model of the circulation.
  • (4) The maintenance of adequate blood circulation requires a sufficient ventricular contractility; in addition, to eject blood, the ventricles must first receive a sufficient volume, requiring a low diastolic stiffness.
