Esta obra introduce al lector en un campo de la investigacion que se halla en continua expansion. La existencia del caos determinista, la aparicion de objetos fractales en la naturaleza o nuestra incapacidad de predecir el futuro, pese a disponer de modelos deterministas, se exponen de forma coherente y a un alto nivel. Asimismo, se analizan con profundidad, mediante diversas aproximaciones teoricas, la aparicion de la complejidad y su cuantificacion, asi como sus implicaciones en campos tan dispares como la evolucion y las extinciones, la dinamica de selvas o de virus emergentes

This book is a Spanish translation of Faecal Sludge Management: Systems Approach for Implementation and Operation It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized...

Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is...
