Desertification Research in Argentina
, 2015 In Latin America, Argentina is second – behind Brazil – in extent of drylands: 55% of its territory. Research on desertification and dryland degradation has a lengthy tradition, being undertaken even prior to the establishment of the United Nations ...

Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]
Sun and Geosphere Vol.9, p. 41-47, No.1 - 2014, 2014 The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with the MAGCOS code), we use backtracking to analyze particles arriving at the location of two nodes of ...

Impacts of geopolitics and policy on Latin American biodiversity and water resources
Agribusiness, EarlyView.Abstract Latin America is a major agricultural producer with important natural resources. Efforts have been made to protect sensitive areas but are hindered by agricultural trade disruptions outside the control of individual countries due to globally integrated crop markets.

Galaxy Formation and Chemical Evolution in Hierarchical Hydrodynamical Simulations [PDF]
arXiv, 2000 We report first results of an implementation of a chemical model in a cosmological code, based on the Smoothed Particle Hydrodynamics (SPH) technique. We show that chemical SPH simulations are a promising tool to provide clues for the understanding of the chemical properties of galaxies in relation to their formation and evolution in a cosmological ...

Chemical Evolution of the Stellar and Gaseous Components of Galaxies in Hydrodynamical Cosmological Simulations [PDF]
arXiv, 2000 We present preliminary results on the effects of mergers on the chemical properties of galactic objects in hierarchical clustering scenarios. We adopt a hydrodynamical chemical code that allows to describe the coupled evolution of dark matter and baryons within a cosmological context.
