The Spanish Society for the Study of Pastures: 45 Years Promoting Better Pasture Knowledge and Management

The Spanish Society for the Study of Pastures (SEEP) (http://www.seepastos.es) was founded in 1960 through the initiative of Prof. G. González with the intention of combining efforts and initiatives on pasture studies from many points of view. The Society has the objective of promoting the knowledge and improvement of Spanish pastures, regarding every issue related with pastoral science: typology; ecology and functions of pastoral ecosystems; plant production; feeding value; animal production; economics; sociology and agricultural policy, etc. The term \u27Pasture\u27 is considered in a broad sense to include every plant part, individual or community capable of being used for livestock or wildlife feeding. Since the inception, the Society has enrolled as members university graduates, engineers, farmers, institutes and companies interested in the soil-vegetation-livestock complex

Curvature(s) of a light wavefront in a weak gravitational field

The geometry of a light wavefront evolving from a flat wavefront under the action of weak gravity field in the 3-space associated to a post-Newtonian relativistic spacetime, is studied numerically by means of the ray tracing method.Comment: 3 pages, 1 fig, Talk given by JFPS at the 12th Marcel Grossmann conference (Paris, July, 2009), submitted to the Proceeding

Geometry of an accelerated rotating disk

We analyze the geometry of a rotating disk with a tangential acceleration in the framework of the Special Theory of Relativity, using the kinematic linear differential system that verifies the relative position vector of time-like curves in a Fermi reference. A numerical integration of these equations for a generic initial value problem is made up and the results are compared with those obtained in other works.Comment: 10 pages, LaTeX, 2 eps figs; typos corrected, added reference, minor changes; submitte
