✦ Synopsis

The dynamical model of a solar prominence taking into account plasma motion in the form of a cumulative flux was developed. Of great importance is the fact that the prominence plasma is partially ionized. Ion-neutral collisions in nonsteady flux conditions radically change the energetics and dynamics of the prominence model. In this case the equilibrium state described by the Kippenhahn-Schltiter solutions becomes unstable, and various dynamic regimes of plasma compression, as well as monotonic or quasiperiodic expansion of the plasma can exist in the prominence.

A dynamical model of prominence loops is constructed on the basis of the theory ofhydromagnetic buoyancy force. A prominence loop is regarded as a flux rope immersed in the solar atmosphere above a bipolar region of the photospheric magnetic field. The motion of a loop is partitioned into a translat

The patterns of diurnal variations in pigmentation and optical cross-section were compared for two cyclostat cultures of Chlorella pyrenoidosa, where the dynamics of the photoperiod differed. Populations were light-limited, nutrient rich and growing on an 8:16 light-dark (LD) cycle. One light regime
