These connections canbe classified in bifurcation families according to the range of values of theassociated Jacobi constant. In the formalism of invariant manifolds (as theaforementioned Jacobi constant changes) the foliation of all Lyapunov orbits isa Normally Hyperbolic Invariant Manifold...

After the launch to a LEO orbit, the orbit of spacecraft has the same inclination with respect to the equator, than the latitude of the launch site on the Earth where the spacecraft was launched. In order to transfer to a GEO orbit the inclination must be reduced to zero. During a GTO it may happen that because of many different problems, the spacecraf...

El siguiente artículo hace una refl exión alrededor de dos alternativas: la medicina occidental y la medicina indígena. Se focaliza en la concepción de salud que manejan estas dos formas de conocimiento, se hace hincapié en la necesidad de revalorar la medicina indígena, y s... Vallejo Samudio, Álvaro Roberto
