Measurements collected included percent time contracting in the anterograde and retrograde directions, the frequency of heartbeat directional reversals, the total contraction rate, the contraction rate when the heart contracts in the anterograde direction, and the contraction rate when the heart contracts in the retrograde direction.
Measurements on abdominal contractions obtained by visualizing mosquitoes restrained in the lateral position included the number of ventral abdominal contractions per minute, the length of abdominal contraction periods, the abdominal contraction rate, and the percent time the abdomen spends contracting.
Each chamber of the heart has its own contraction rate.
It now estimates the contraction rate at 8.9 percent.
In contrast, the contraction rate of the diseased cells only increased by about 37percentt, and the force of the contraction remained roughly the same.
While oxygen availability was found to impact in vitro contraction rate and the orientation of contractile movement, it was not a key factor in enabling contractility.
It has been shown that the gastrointestinal system changes wall tonus and contraction rate during stressful tasks.
When the researchers treated the cells with molecules that blocked the function of the phosphodiesterase proteins, diseased cells responded more strongly to isoproterenol treatment, and their contraction rate and force approached that of healthy cells.
Penetration increased with contraction rate by 1.5-fold from baseline to a maximum at 0.5 Hz, revealing architectural modulation of dispersion.
The idea of divergence characterisation of the expansion (or contraction) rate of the object and fluid volume can be extended to the thermal pattern characterisation of ECPT.
It is seen that contraction rate of specimen thickness is bigger than that of the width of specimen during plastic deformation.
