13. Manobras orbitais aplicadas aos problemas de dois e tres corpos
In the space activities, it is of great importance the study of the trajectories that the space vehicles should follow to complete a mission. With that motivation, the present research is concentrated in the study of those trajectories, under the dynamics given by: a)The traditional Problem of Two Bodies with Keplerian orbits where the space vehicle is suppo

15. Charge calculations in molecular mechanics 6: the calculation of partial atomic charges in nucleic acid bases and the electrostatic contribution to DNA base pairing.
A previously described scheme for the direct calculation of the partial atomic charges in molecules (CHARGE2) is applied to the nucleic acid bases. It is shown that inclusion of the omega-technique for the calculation of HMO derived pi charges is of particular importance for these highly polar systems. The molecular dipole moments obtained for the resulting
