Regiões de estabilidade no ambiente de um sistema de asteroide triplo

This work was developed from the study by Araujo, R.A.N. et al. Stability regions around the components of the triple system 2001 SN263. (Monthly Notices Of The Royal Astronomical Society, 2012, v. 423(4), 3058-3073 p.) where it was studied the stable and unstable regions system (2001 SN263), which is a triple asteroid system, and these are celestial orbiting our sun. Being close to the Earth is characterized as NEA (Near-Earth Asteroids), asteroids and which periodically approach the Earth's orbit, given that there is great interest in the study and exploitation of these objects, it is the key can carry features that contribute to better understand the process of formation of our solar system. Study the dynamics of bodies that govern those systems proves to be greatly attractive because of the mutual gravitational perturbation of bodies and also by external disturbances. Recently, NEA 2001 SN263 was chosen as a target of Aster mission where a probe is sent for this triple system, appearing therefore the need for obtaining information for characterizing stable regions internal and external to the system, with respect to the effects of radiation pressure. First, this study demonstrated that the integrator used showed satisfactory results of the orbital evolution of bodies in accordance with previous studies and also the characterization of stable and unstable regions brought similar results to the study by Araujo et al. (2012). From these results it was possible to carry out the implementation of the radiation pressure in the system in 2001 SN263, in a region close to the central body, where the simulations were carried out, which brought as a result that the regions before being characterized as stable in unstable true for small particles size from 1 to 5 micrometers. So the next orbital region to the central body and the ... ( Complete abstract click electronic access below)

As lógicas espaciais do sistema bancário: reestruturação das cidades de Marília, Ribeirão Preto e São Carlos

Esa tesis presenta un breve histórico sobre el sistema bancario brasileño, buscando entender las lógicas espaciales en tres ciudades paulistas - Marília, Ribeirão Preto y São Carlos - asociando el abordaje, sobretodo, al contexto de las ciudades intermedias, que es el caso de las las ciudades estudiadas en esta investigación. Realizamos este análisis a través del trabajo con algunas hipótesis sobre lógicas espaciales, refuerzo de la centralidad urbana y nuevas tendencias, con el fin de comprender posibles prácticas espaciales resultantes de reestruturacción urbana y de la ciudad, tomando en consideración que la fuerte presencia de distintas agencias, junto a los espacios comerciales de las ciudades, confirma la importancia comercial que estas ciudades tienen, revelando relaciones entre su ubicación y las posibilidades de atraer usuarios. Por lo tanto, el estudio de las lógicas espaciales ejecutadas por los grandes grupos que operan el sistema bancario ha tenido papel importante en la articulación entre reestruturación urbana y de las ciudades
