The crystal structures of 4-nitro-9,10-dihydrophenanthrene, C14H11NO2, (I), and 4-nitrophenanthrene, C14H9NO2, (II), the latter having two crystallographically independent molecules, show that the molecules are not planar. The dihedral angles between the phenyl rings of the biphenyl skeletons are 28.64 (8) degrees for (I), and 10.34 (15) and 11.75 (13)(More)

Mathematical modeling of aging effects in adulthood was performed, using the spatio-temporal characteristics in the motion of the facial landmarks with the skin mechanical properties. The smiling motions (MLCR) and the skin properties (firmness and elasticity) were measured for 56 female adults classified into the two age categories in adulthood (young(More)
