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...

(Complete work in Spanish) Remote sensing aerial spectral imaging was one of the first application areas where spectral imaging was used in order to identify and monitor the natural resources and covers on earth surface. Aerial spectral imaging is being developed with the aim of monitoring natural resources like coastal areas, forestry and extensive crops. The information contained in hyperspectral images allows the reconstruction of the energy curve radiated by the terrestrial surface throughout the electromagnetic spectrum. Hence, the characterization, identification and classification of...

Este es un libro para los que se inician en la investigación, que en un solo volumen, relativamente pequeño, hace un estudio de los métodos experimentales de tipo general, que han demostrado ser particularmente útiles en el campo de la Química inorgánica.

Estudio realizado por científicos mexicanos dirigido a explicar la manera en que la energía solar es susceptible de ser aprovechada por medio de la química y sus fenómenos reactivos que podrían convertirla en una fuerza motriz que sustituyera a las muy contaminantes que existen.
