This chapter analyzes the importance of the income generated from oil and gas industries to municipalities in the state of Rio de Janeiro and the consequences of this dependency. The importance of the taxes, royalties and other revenues generated by this industry to the municipal budgets show a great exposure to an extremely volatile situation derived from the dependency of finite resources whose price is defined by the flotation of international markets. The effort of demonstrating the dependency of these municipalities to these taxes and royalties aims to flag the risks of having such a profile of income that is prone to variation, not only as a consequence of the fluctuation in the production or of the international price, it also has to do with changes in the legislation that rules on the matter of the distribution of the royalties and taxes among the federative entities. It is safe to say that the dependency in these terms strengthens the unpredictability of local government's budgets and, consequentially, weakens long-term policy elaboration and execution. The main conclusion of this text is that this instable scenario is aggravated by the expectation of incremental investment in the oil and gas exploitation in pre-sal fields in the Santos Bay (SP) due to the expectation of higher productivity of these fields. In the possibility of confirming this scenario, the municipalities that confront the sea-area of the Campos Bay production fields will keep on being affected in their budget and in the diffuse investments, employment and income that the industry brings with it.

The relationship between molecular conformation and substituent effects of salicylaldehyde Schiff-base Cu(II) complexes was explored. For this study, eight samples of the complexes Cu(Sal-X)(2) (X = OMe, Me, H, F, Cl, Br, CF3 and CN) were obtained by reaction of Cu(OAc)(2) with Schiff base ligands (Sal-X) derived from Salicydaldehyde, and their crystal structures were characterized by the X-ray diffraction technique. The QSPR methods were employed to achieve deeper insight into geometry structure of Cu(Sal-X)(2). The results show that the main geometrical parameters of Cu(Sal-X)(2) are dominated by the substituents on the aniline ring. That is, the dihedral angle tau(1) between the Cu-O-N plane and O-C=N plane increases with the increase of electron-donating effect and electron-withdrawing effect of substituents, whereas the electronic effect of substituents has the opposite effect on tau(2), which is the dihedral angle between the aniline ring plane and C-N-Cu plane. Moreover, the bond length Lcu-N decreases with growing excited- state parameter sigma(ex)(cc) of substituents which enhances the energy of C-N bond. (C) 2020 Elsevier B.V. All rights reserved.
