Symmetric periodic orbits near heteroclinic loops at infinity for a class of polynomial vector fields
(2006)For polynomial vector fields in R3, in general, it is very difficult to detect the existence of an open set of periodic orbits in their phase portraits. Here, we characterize a class of polynomial vector ... -
Generation of symmetric periodic orbits by a heteroclinic loop formed by two singular points and their invariant manifolds of dimension 1 and 2 in R3
(2007)In this paper we will find a continuous of periodic orbits passing near infinity for a class of polynomial vector fields in R3. We consider polynomial vector fields that are invariant under a symmetry ... -
Central configurations of three nested regular polyhedra for the spatial 3n–body problem
(2009)Three regular polyhedra are called nested if they have the same number of vertices n, the same center and the positions of the vertices of the inner polyhedron ri, the ones of the medium polyhedron ... -
Central configurations of nested regular polyhedra for the spatial 2n–body problem
(2008)We consider 2n masses located at the vertices of two nested regular polyhedra with the same number of vertices. Assuming that the masses in each polyhedron are equal, we prove that for each ratio of ... -
Central configurations of nested rotated regular tetrahedra
(2009)In this paper we prove that there are only two different classes of central configura- tions with convenient masses located at the vertices of two nested regular tetrahedra: either when one of the ... -
Challenging equality policies: The emerging LGBT perspective
(2013)The state members of the European Union have witnessed the emergence of equality policies which target discrimination on the grounds of sexual orientation and gender identity. These are usually based ... -
Food Indicators and Their Relationship with 10 to 12 Year-olds' Subjective Well-Being
(2012)This study aimed to test subjective indicators designed to analyze the role food plays in children’s lives, explore children’s personal well-being, and evaluate the relationship between these two ... -
On the existence of bi-pyramidal central configurations of the n + 2-body problem with an n-gon base
(2013)Abstract. In this paper we prove the existence of central con gurations of the n + 2{body problem where n equal masses are located at the vertices of a regular n{gon and the remaining 2 masses, which ... -
Double-Antiprism Central Configurations of the 3n-Body Problem
(2013)Abstract In this paper we study numerically a new type of central configurations of the 3n-body problem with equal masses which consist of three n-gons contained in three planes z = 0 and z = ±β = ... -

Metaphors, women and translation: From les belles infidèles to la frontera
(2013)One of the main concerns of translation theory from the 17th century till today has been the problem of how to be faithful to the original text. Further, this concern regarding both the origin and the ... -
