Zonas de planificación para accidentes graves de tipo térmico

Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore -- there are huge yawning voids in our basic notions of how the world works. Jorge Cham and Daniel Whiteson team up to explore everything we don't know about the universe, and while introducing the biggest mysteries in physics, they also helpfully demystify many complicated things we do know. And although the universe is full of weird things that don't make any sense, Cham and Whiteson make a case that the questions we can't answer are as interesting as the ones we can, and they invite...

Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as...

El libro presenta los aspectos referidos a la dinámica de cambio que ha impuesto la naturaleza sobre las condiciones macro-ecológicas de los Andes desde la era arcaica y formativa de las culturas agrarias andinas peruanas que ocuparon el territorio peruano. Principalmente se ocupa de las modificaciones en las condiciones geo-hidrográficas y de clima-vegetación que se han producido, relacionadas a los periodos de cambio climático universales repercutiendo en el paisaje y el Hombre en las zonas andinas peruanas. Una visión histórica acerca del desarrollo de las poblaciones y culturas...

The Inter-American Development Bank (IDB), in cooperation with the International Water Association (IWA), has developed a rating system that assesses the performance of water and sanitation service providers in a comprehensive way. AquaRating: Un estándar internacional para evaluar los servicios de agua y saneamiento aims to provide an industry standard for utilities. The innovative rating system seeks the improvement of the service delivered by means of a rigorous and systematic assessment. AquaRating comprises more than 100 assessment elements organized in eight rating areas: Service...
