Modelos da Química Quântica no espaço de momento: diferentes representações de um mesmo sistema
(Sociedade Brasileira de Química, 2009)
The conventional approach to simple quantum chemistry models is contrasted with that known as momentum representation, where the wavefunctions are momentum dependent. Since the physical interactions are the same, state ...
RELATIVISTIC-DFT STUDY OF THE ELECTRONIC STRUCTURE, BONDING AND ENERGETIC OF THE [ReF8]־ AND [UF8]2- IONS
(Sociedad Chilena de Química, 2013-12)
In this study we evaluated the importance of the relativistic effects (scalar and spin-orbit) on the description of the electronic structure, bonding and the energetic of the [ReF8]- and [UF8]2- ions. We described the ...

(BMC, 2020)
BackgroundFinding new strategies for care integration has become a policy priority for many fragmented health systems in Latin America. Although the implementation of interventions through a participatory action research ...
Associativity in the Bogotá metropolitan region: coordination challenges in a fragmented regionAsociatividad en la región metropolitana de Bogotá: desafíos de coordinación en una región fragmentada
(Area Development and Policy, 18/01/2021)
The Bogotá Metropolitan Region represents a paradox as it is yet to establish a metropolitan entity. The official discourse on the integration of Colombia’s capital city, Bogotá Capital District, with its surrounding ...
Effective coordination concept applied for phase change (GeTe)(m)(Sb(2)Te(3))(n) compounds
(AMER INST PHYSICS, 2011)
In this work, we employed the effective coordination concept to study the local environments of the Ge, Sb, and Te atoms in the Ge(m)Sb(2n)Te(m+3n) compounds. From our calculations and analysis, we found an average effective ...
