ABSTRACTThis review presents a summary of observed photospheric phenomena on RS CVn stars: the amplitude, shape, evolution and migration rate of the photometric wave in relation to the rotational and orbital motion.The main points considered are: 1) the activity level (maximum amplitude, short and long timescale variability) versus rotation period; 2) the activity cycles as inferred from changes in the wave migration rate and direction and from the variation of its amplitude; 3) the detection of differential rotation; 4) the connection between the orbital period variation and activity.

AbstractIn situ observations of CIGM in CaCO3 bicrystals with a SrCO3 solute source were made. The change in boundary orientation and migration rate were compared with solute concentration. The liquid film model for coherency strain Induced migration was generalized to any non-cubic system and applied to CaCO3-SrCO3. The coherent layer was modeled as a thin film on an infinite half-space. The strain energy was found from solution of the Hooke's law expressions transformed to the appropriate coordinate system. For triclinic or monoclinic films the strain tensor was found by an eigenvector decomposition of the transformation matrix that defined the lattice parameter change with composition. High anisotropy of Vegard's law constants for CaCO3-SrCO3 caused (111) to have the lowest coherency strain per unit solute. Surfaces perpendicular to (111) in coherent equilibria were predicted to have half the solute concentration and three times the migration driving force of those perpendicular to (111). However, no correlation between solute concentration and boundary orientation was observed. Ambiguous and contradictory evidence for a relationship between solute concentration, boundary orientation, and migration rate was found. The self-stress state of a grain boundary in a solute diffusion field may be better modelled as hydrostatic rather than plane stress. Hydrostatic compression may interact with the boundary excess volume and cause a PV driving force for migration. Predictions based on coherent equilibrium at a surface have not been tested for that geometry in calcite; they should be tested before they are applied to grain boundaries.

Abstract Photobiomodulation (PBM) has been used as a bio stimulatory tool for adipose-derived mesenchymal stem cells (ADMSCs). The goal of this in vitro research was to examine the effects of combined and/or single applications of near infra-red (NIR) and green PBM using 5 J/cm2 on ADMSCs. The results indicated that the viability of ADMSCs are not affected by single or combined wavelengths of 525 and 825 nm at 5 J/cm2. However, PBM significantly stimulated cell metabolism seen by an increase in proliferation, it also upregulated intracellular ROS and MMP using 825 nm and 525 nm wavelengths. The combined wavelength irradiation mimicked results found for 825 nm during ATP measurement, cell concentration and migration rate, however significant MMP stimulation and increased ROS production was achieved. In conclusion, results indicate that the combination wavelengths of 525 and 825 nm can be used in the expansion and differentiation of ADMSCs for regenerative purposes.
