Query: On possible explanations of pulsations in Maia stars   The long-time photometric surveys in a few young open clusters allowed to
identify the light variability in stars located on the HR diagram between the
well defined $\delta$ Scuti variables and Slowly Pulsating B-type stars.
Several objects of this type were suggested also from the analysis of the
Kepler data. Assuming the pulsational origin of this variability, we try to
explain the observed frequencies with pulsational models involving rotation
and/or modification of the mean opacity profile.
