Enumeration of benzenoid chemical isomers with a study of constant-isomer series,≡|., .| is the number of isomers pertaining to the particular formula. The generation of benzenoid isomers (.) is treated and some fundamental principles are formulated in this connection. Several propositions are proved for special classes of benzenoids defined in relation to the place of their for

The synthon model and the program PEGAS for computer assisted organic synthesis,nd those vertices are called the virtual vertices. The virtual vertices correspond to functional groups or molecular fragments that do not directly participate in chemical transformations (though these transformations may be substantially influenced by them). The synthon precursors or successors are

Sónia Avelarus on governments as the main custodians of national stability and economic growth was replaced increasingly by a focus on market forces, civil society and good governance. In addition, relief aid started figuring prominently on the international agenda, sometimes at the expense of traditional devel
