Hydrodynamics-Biology Coupling for Algae Culture and Biofuel Production

International audienceBiofuel production from microalgae represents an acute optimization problem for industry. There is a wide range of parameters that must be taken into account in the development of this technology. Here, mathematical modelling has a vital role to play. The potential of microalgae as a source of biofuel and as a technological solution for CO2 fixation is the subject of intense academic and industrial research. Large-scale production of microalgae has potential for biofuel applications owing to the high productivity that can be attained in high-rate raceway ponds. We show, through 3D numerical simulations, that our approach is capable of discriminating between situations where the paddle wheel is rapidly moving water or slowly agitating the process. Moreover, the simulated velocity fields can provide lagrangian trajectories of the algae. The resulting light pattern to which each cell is submitted when travelling from light (surface) to dark (bottom) can then be derived. It will then be reproduced in lab experiments to study photosynthesis under realistic light patterns

El nexo entre diplomacia preventiva y desarrollo económico social a inicios del siglo XXI. Desafíos y perspectivas

La historia del siglo XX está marcada por conflictos tanto internacionales como a nivel interno. En 1918-19 tras la Gran Guerra, hubo un empeño extraordinario por poner fin a los conflictos de tal envergadura. Sin embargo, estos primeros intentos no resultaron exitosos, desencadenándose en 1939 la Segunda Guerra Mundial. Desde 1945, el miedo a una tercera guerra mundial se ha convertido en una constante fundamental de nuestra realidad histórica y ha supuesto una gran inquietud en el ámbito de la geopolítica. La preocupación por un nuevo conflicto a nivel mundial con los actuales medios de destrucción ha forzado la creación de instrumentos para velar por el mantenimiento de la paz, siempre teniendo en cuenta que es deseable prevenir el conflicto, antes de tener que lamentar las acciones que se derivan de él. Éste fue uno de los objetivos de la Conferencia de San Francisco, que creó la Organización de las Naciones Unidas (ONU) en 1945, cuyos propósitos fueron garantizar la paz y preservar las generaciones futuras de los flagelos de la guerra. Frente a una constante amenaza a la estabilidad y la seguridad internacional derivadas de múltiples factores, la diplomacia preventiva se considera como la opción privilegiada para preservar la paz y la seguridad internacional. De ahí, el trabajo aspira a analizar y aclarar el nexo que debe existir entre la diplomacia preventiva y el desarrollo económico y social como medios para evitar potenciales conflictos..
