Comprehensive Study

In a comprehensive study, structural properties, electronic structure and optical response of crystalline o-phenanthroline were investigated. Our results show that in generalized gradient approximation (GGA) approximation, o-phenanthroline is a direct bandgap semiconductor of 2.60 eV. In the framework of many-body approach, by solving the Bethe–Salpeter equation (BSE), dielectric properties of crystalline o-phenanthroline were studied and compared with phenanthrene. Highly anisotropic components of the imaginary part of the macroscopic dielectric function in o-phenanthroline show four main excitonic features in the bandgap region. In comparison to phenanthrene, these excitons occur at lower energies. Due to smaller bond lengths originated from the polarity nature of bonds in presence of nitrogen atoms, denser packing, and therefore, a weaker screening effect, exciton binding energies in o-phenanthroline were found to be larger than those in phenanthrene. Our results showed that in comparison to the independent-particle picture, excitonic effects highly redistribute the oscillator strength.

Comprehensive Study

Prior to the 1930s, designs of research into sexual behavior of infrahuman primates were not comparable; conclusions about physiological and nonphysiological factors in receptivity and mating were confounded by species studied, living and testing conditions, and precaptivity history. Clearly there was need for comprehensive and controlled studies of infrahuman primate sexual behavior. In response to the controversy about biological bases of receptivity and mating, James Harlan Elder, in collaboration with Robert M. Yerkes, designed the first truly comprehensive study of factors influencing sexual behavior of chimpanzees. At that time, other persons interested in this problem were employing experimental methods, but Elder's and Yerkes' program most directly addressed the problems confounding prior study and their work served as a model of experimental research into factors affecting receptivity and mating of infrahuman primates.
