The phrase "activity during the initial" is correct and usable in written English.
It can be used when discussing actions or tasks that take place at the beginning of a process or event.
Example: "The activity during the initial phase of the project was crucial for setting the foundation for future success."
Alternatives: "actions in the early" or "tasks at the outset".
Thus, to determine the potential for CDK4 activity during the initial 8 h of stimulation, activated B cells were analyzed for levels of cyclin D2 (the predominant cyclin D family member in B cells) [27], [28].
Significantly rapid deactivation behaviour occurred at the higher temperatures of 230 to 270 °C, with greater cracking activity during the initial few minutes, resulting in a very high rate of coke formation, which also accounted for the poor performance.
At the higher temperatures of 250 and 270 °C, it showed a rapid fall in catalyst activity during the initial few hours, followed by a constant deactivation rate being reached, which ranges from 3 and 5 wt% every 24 h until the reaction terminated.
This finding is consistent with that of previous studies reporting the importance of transcriptional activity during the initial response to NGF [28].
This result indicates that transcriptional activity during the initial 3 h is critically important for the action of the first stimulation, but not needed for the action of the second stimulation.
Further analysis revealed that both strains of rats displayed similar locomotor activity during the initial period of testing (i.e., first 10 min; Figure 1A).
This table shows that the instructors' activities during the initial training sessions are determined by 12 themes (7 themes for track training and 5 for road training).
This paper reports on activities during the initial phase of the five-year project that aims to inform the global knowledge pool on the research-policy interface in low and middle income countries.
In the current study, SHRs showed increased levels of rearing activity during both the initial novelty phase and the habituation period of open field testing.
Progesterone decreases the maximal level of enzyme activity achieved during the initial burst.
Biphasic cervical bursts (B, F – G ) show lumbar activity primarily during the initial cervical peak.
