After the CM injection is started, a low-dose monitoring scan is performed at a predetermined level after a fixed time delay, usually 5 s, and thereafter every 1-3 s until the enhancement in the ROI reaches a specified level (typically 150 HU).
Secondly, using predefined training goals (the expert proficiency level) instead of fixed time or numbers, encouraged the trainees to rehearse until they reached the maximal effect of the simulator training.
44, 45, 47 Third, vitamin D level was only measured at fixed time points (baseline, months 6, 12, and 24), and not at the time of relapses.
Classes are scheduled at a fixed time.
FT: fixed time schedule of reinforcement.
Planning routines used fixed times for surgeries.
By mapping a fixed domain onto the evolving domain at each time level, we generalize to evolving domains the ADI extrapolated Crank Nicolson orthogonal spline collocation technique developed in [8], [9] for fixed domains.
We also include time fixed effects, ( {rho}_t ), grade level fixed effects, ( {sigma}_g ), and school-by-year fixed effects, ( {alpha}_{st} ), in the model.
Figure 6 shows the three-dimensional response surface plot of LPAC yield comprising effect of activation temperature and activation time, while IR was kept at zero level (IR = 2.25) whereas Fig. 7 illustrate the effect of activation temperature and IR on the response, with activation time fixed at zero level (t = 2 h).
