Stability of the rhombus configuration with a central body
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAUFMG, 2017-01)
Consideramos um sistema plano de cinco corpos respectivamente localizados em r0, r1, r2, r3 e r4 com massas m0 ≥ 0, m1 = m2 = me m3 = m4 = ˜m movendo-se em um plano. O corpo de massa m0 é considerado o centro da configuração ...
The Sitnikov problem for several primary bodies configurations
(Springer, 2018-07)
In this paper we address an n+ 1 -body gravitational problem governed by the Newton’s laws, where n primary bodies orbit on a plane Π and an additional massless particle moves on the perpendicular line to Π passing through ...
Configurational entropy of adsorbed linear species (k- mers)
(American Institute of Physics, 2001-06-11)
The configurational entropy of interacting linear molecules (k-mers) absorbed on a regular lattice is addressed through analytical as well as numerical methods. The general definitions for computational exact calculations ...
Land grabbing, power configurations and trajectories of China’s investments in Argentina
(Routledge Journals, Taylor & Francis Ltd, 2021-07)
This paper analyses the display of the power relations involved in the trajectory of China´s land grabbing in Argentina. Through a study of the failed agri-food project of Beidahuang Group in Rio Negro, it shows the ...
A hybrid configuration interaction treatment based on seniority number and excitation schemes
(American Institute Of Physics, 2014-12)
We present a configuration interaction method in which the Hamiltonian of an N-electron system is projected on Slater determinants selected according to the seniority-number criterion along with the traditional excitation-based ...
