The great diversity and richness of transition metal chemistry, such as the features of an open d-shell, opened a way to numerous areas of scientific research and technological applications. Depending on the nature of the metal and its environment, there are often several energetically accessible spin states, and the progress in accurate theoretical treatment of this complicated phenomenon is p...

Changes in the levels of haemolymph metal ions of two binoltine races of the silkworm, Bombyx mori (NB4D2 and CSR2) and the multivoltine race (Pure Mysore ) was studied at different stages of larval and pupal development. The haemolymph metal ions showed significant changes during different stages of larval development like moult, post-moult, feeding and spinning and pupal stages like pre-pupa,...
