It is widely recognized that the degree of development of a science is given by the transition from a mainly descriptive stage to a more quantitative stage. In this transition, qualitative interpretations (conceptual models) are complemented with quantification (numerical models, both, deterministic and stochastic). This has been the main task of mathematical geoscientists during the last forty years - to establish new frontiers and new challenges in the study and understanding of the natural world. Mathematics of Planet Earth comprises the proceedings of the International Association for Mathematical Geosciences Conference (IAMG2013), held in Madrid from September 2-6, 2013. The Conference addresses researchers, professionals and students. The proceedings contain more than 150 original contributions and give a multidisciplinary vision of mathematical geosciences.
This volume provides an original analysis of the role of foreign firms in the structural reforms implemented by the Latin American governments since the 1980s with a focus on the making of the Spanish multinational enterprise.
The reactive scattering for H- + H2 and H+ + H2 and its isotopologues were investigated using different methods. The studies aimed at providing insights into elementary reactions, and go beyond these to more complexchemical reactions. By comparison of the reaction probabilities of H+ + H2 using adiabatic and non-adiabatic methods, it was found that, at low collision energies, the reaction preferentially occurs adiabatically, but at higher collision energies non-adiabatic effects should be taken into account. For H- + H2 and its isotopologues, we can see that, at low collision energies, the reaction probabilities and reaction cross section using SM-PES and AY-PES are very similar but different from PS-PES. The reaction cross sections investigated with quasi-classical trajectoriesare higher than those calculated with quantum wavepackets. For the collision H- and D- with HD, the main reaction path ways are different with the different collision energies.
In 1914 Twitchell published in two volumes, "The Spanish Archives of New Mexico," the first calendar and guide to the documents from the Spanish colonial period. The bulk of the records accentuate the amazingly dynamic nature of land grant and settlement policies.
