El destino partido por infinito y la raíz cuadrada de Dios

Explore the everyday miracle of the microscopic world With spectacular macro photography and microscope images, this book reveals a hidden, living world full of intricate structures beyond the naked eye. Included are the tiniest insects and spiders; but looking deeper, you will discover truly microscopic creatures--even bacteria and viruses. Earth is home to more microbes, and more different types of microbes, than any other living organism. Bacteria on Earth outweigh humans by 1,100 to 1; and without them, all world ecosystems would collapse. This book reveals this vital, unseen realm, but...

The section devoted to iron in this volume reflects the tremendous progress in the area. Specifically cluster chemistry, ligand transformations and detailed structural results are more prominent in COMC II. The organic chemistry of ruthenium and osmium is an area which has burgeoned during the period since the publication of COMC. This is especially true for the cluster chemistry of these elements, which have provided most of the advances in this important field. Consequently, this volume will include an update (1981-1993) of the chemistry of mono- and bi-nuclear complexes of ruthenium and...

El manejo sostenible y sustentable del agua, la eficiencia en su uso, su transporte y su conservación, se han convertido en temas estratégicos para la sociedad actual, en particular en los grandes centros urbanos donde los problemas de escasez de agua y contaminación de las fuentes se han vuelto críticos. También en el uso agrícola de este recurso, donde los riegos representan alrededor del 70 % del consumo humano de agua, es un problema que debe ser enfrentado por la ingeniería. El propósito de este libro es apoyar la labor de los ingenieros encargados del manejo de los recursos...

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 ...
