Aggressive behavior of white-eye mutant crickets was investigated and compared with that of wild-type crickets. In the dark, wild-type pairs performed long-lasting fights with significantly higher aggressive levels compared to those in the light.

Space-configurational features of atactic poly(acrylic acid) in unperturbed and expanded states were analyzed in terms of the extending and coiling tendency of the backbone bond rotational states. Conformational energy calculations were performed for dyads using semi-empirical relations and the statistical analyses using statistical weight matrices U' and U" for respective dyad skeletal bond pa...
