Quantum-like structure is present practically everywhere. Quantum-like (QL) models, i.e. models based on the mathematical formalism of quantum mechanics and its generalizations can be successfully applied to cognitive science, psychology, genetics, economics, finances, and game theory. This book is not about quantum mechanics as a physical theory. The short review of quantum postulates is therefore mainly of historical value: quantum mechanics is just the first example of the successful application of non-Kolmogorov probabilities, the first step towards a contextual probabilistic description...

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...

La resolució d'exercicis i de problemes que es proposa en aquest treball, requereix, al seu torn, de l'estudi de Física de partícules i astropartícules. L'obra està dividida en cinc parts. En la primera es presenten els exercicis sobre els constituents elementals; en la segona sobre els mètodes experimentals; la tercera està dedicada a les simetries i els hadrons; la quarta a les interaccions entre constituents elementals i la cinquena desenvolupa els problemes referents a astropartículas i experiments amb neutrins.

El deterioro obvio de los ambientes acuáticos, tanto dulces (ríos, lagos y embalses) como costeros (lagunas, estuarios, bahías, marismas), es resultado de los cambios provocados por las diversas actividades antropogénicas, teniendo como consecuencia que la calidad del agua que sostiene a una gran variedad de organismos se haya visto alterada en diverso grado. Bajo este panorama algunos organismos acuáticos pueden resistir adaptándose a condiciones deletereas definiendo así al ambiente, u otros desaparecer por no soportar condiciones de impacto. De esta manera surge la necesidad de...
