  • (18) This controller design is based on the physical models of the actuator and blood pump system.
  • (19) The properties of the afferent fibres from the capsule of the hip joint have been studied in the cat in situ, in relations to joint rotation, and in an isolated capsule preparation which was opened and stretched directly with an actuator.
  • (20) The efficacy and safety of cromolyn sodium by metered-dose inhaler (MDI) (1 mg per actuation) was evaluated with a double-blind, placebo-controlled, parallel-study design.

Mechanism


Definition:

  • (n.) The arrangement or relation of the parts of a machine; the parts of a machine, taken collectively; the arrangement or relation of the parts of anything as adapted to produce an effect; as, the mechanism of a watch; the mechanism of a sewing machine; the mechanism of a seed pod.
  • (n.) Mechanical operation or action.
  • (n.) An ideal machine; a combination of movable bodies constituting a machine, but considered only with regard to relative movements.

Example Sentences:

  • (1) Such a signal must be due to a small ferromagnetic crystal formed when the nerve is subjected to pressure, such as that due to mechanical injury.

  • (4) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
  • (5) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
  • (6) It is concluded that amlodipine reduces myocardial ischemic injury by mechanism(s) that may involve a reduction in myocardial oxygen demand as well as by positively influencing transmembrane Ca2+ fluxes during ischemia and reperfusion.
  • (7) Models able to describe the events of cellular growth and division and the dynamics of cell populations are useful for the understanding of functional control mechanisms and for the theoretical support for automated analysis of flow cytometric data and of cell volume distributions.
