Aims: In this paper, we analyze the collisional and dynamical evolution of the population of Plutinos. Methods: To do this, we test different collisional parameters and include a dynamical treatment that takes into acc...

This thesis presents the development and simulation of a modular physically based thermal model of a building and a reversible R290 (propane) air-to-water heat pump, implemented in MATLAB/Simulink and Simscape. The work ...

Conventional wisdom indicates that a millisecond pulsar is recycled during the mass transfer stage in a binary system. Usually, the companion to the pulsar is a low-mass white dwarf. If zero ages are set at the end of ma...

Context: It is widely accepted that the large obliquity of Uranus is the result of a great tangential collision (GC) with an Earth size proto-planet at the end of the accretion process. The impulse imparted by the GC aff...

With the aim of studying the final mass distribution of extrasolar planets, we have developed a simple model based on the core instability model, which allows us to form a large population of planets and make them evolve...

The theory of satellite loss resulting from a giant impact on Uranus (Parisi and Brunini 1997, Planet. Space Sci. 45, 181–187) is revisited, in the light of the discovery of its five outer moons (Gladman et al. 1998, N...

Atualmente, muito se tem discutido nos campos farmacêutico e dermocosmético sobre os riscos da exposição exagerada às radiações UVA e UVB. Neste contexto, a fotoproteção assume papel fundamental na manutenção ...

Fil: Goya, María Eugenia. Universidad Nacional de Quilmes. Departamento de Ciencia y Tecnología. Laboratorio de Cronobiología; Argentina. Los ritmos circadianos están basados en relojes endógenos que les permiten a ...
