Furthermore, the duration of steps for neckless myosin was several times longer at saturated ATP concentration, indicating that the slower velocity was due to a slower dissociation rate of myosin heads from actin.
Thus, for any value of post-saccadic duration, the total duration of stepped target was increased in our study by a value corresponding to the saccadic duration (about 40 ms).
Error signals were tested by setting the post-saccadic duration of stepped target (hereafter called "target duration") at 15, 50, 100 and 800 ms in separate sessions and, in some sessions, by replacing the stepped target by a visual mask.
The aim of the present study was to measure the dynamics of EELV changes (ΔEELV) after a step increase or decrease in PEEP (ΔPEEP) to determine the optimal duration of steps during a SRM and a decremental PEEP trial.
Another study reported that the frequency of KI-67-positive tumor cells was dependent, in part, on the nature and duration of steps in the immunohistochemistry procedure (Mengel et al. 2002 ).
Indeed, over extension of the duration of either step 1 or step 2 leads to deterioration of the overall corrosion resistance.
What is interesting though is while the physical activity increased among the treatment group in terms of steps, aerobic steps and duration of aerobic steps, this had relatively little short-term impact on body fat, and no sustained effect on body fat.
The duration of each step was 3 min, except for the 26 cmH2O step and ZEEP (6 min each; Figure 1).
Three variables (total volume of hexane, number of extraction steps and duration of such steps) were elected as factors in the optimization study.
