Comprendiendo el infinito

Esta nueva edición de la ya conocida obra de Raymond A. Serway y John W. Jewett Jr., además de conservar la gran capacidad didáctica que la ha caracterizado, ahora cuenta con el respaldo de las herramientas tecnológicas que proveen de un mayor soporte al usuario a lo largo del curso.

En Shock climático, Gernot Wagner y Martin Weitzman analizan las probables repercusiones del calentamiento global, apoyándose en investigaciones que hasta hace poco no eran conocidas. Los autores nos ayudan a comprender que debemos pensar en el cambio climático tal y como pensamos en asegurar nuestra casa o nuestro automóvil: como un problema de gestión de riesgos, sólo que en este caso a escala global. Shock climático insta a afrontar el cambio climático y proporciona los instrumentos para hacerlo —además de describir las consecuencias de no hacerlo—, ofreciendo un análisis...

Soil is a pivotal component of the environment and the maintenance of soil quality is critical for ensuring the sustainability of the environment and the biosphere. The use of fertilizers has increased at a faster rate than global food production. Modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource. It is needed to improve P acquisition efficiency for both low input and intensive agroecosystems. However, few studies have focused on cereal-legume interactions with regard to soil P. The objective of this work was to study the effects of...

hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known ...
