The analysis was based on a global optimization routine that finds good initial values for an adaptive Markov chains Monte Carlo (MCMC) algorithm that finally computes the posterior parameter distribution. A revised activated sludge model was used in order to perform a comparison between Bayesian and linear theory methods. It was observed that the linear theory method systematically underestimates the confidence intervals of the estimated model parameters because the multivariate normality assumption is violated and practical unidentifiability for some parameters occurs. 2011-10-21T11:22:12Z http://hdl.handle.net/2117/12245 Title: Manure treatment technologies: on-farm versus centralized strategies.

Los tratamientos con fangos han provocado un aumento del contenido total y asimilable de los metales traza en el suelo. A nivel foliar solo el sistema de aplicación directa y dosis alta presenta contenidos superiores al control (Zn, Cu, Pb), y a lo largo de la experiencia los niveles van disminuyendo. El principal efecto negativo del uso de fangos es el elevado contenido en nitratos de la cubierta vegetal durante el primer año de experiencia, que la hacen inadecuada como alimentación para el ganado. 2011-02-01T12:58:50Z http://hdl.handle.net/2117/10629 Title: Contribution a la comprehension de la qualité des sols de la steppe algerienne (Cas du secteur El Bayadh-Brezina, ouest de l'Algerie) Authors: Boukhari, Y.; Josa March, Ramon; Mas Serra, Maite; Mederbal, K.; Verdú González, Antoni Maria Claret; Tadjeddine, N.; Regagba, Z.; Ouldali, O.; Khader, M. 2010-12-16T10:20:09Z http://hdl.handle.net/2117/10601 Title: Ecosystemes steppiques(Cas de Brezina– El Bayadh) Authors: Verdú González, Antoni Maria Claret; Mederbal, K.; Josa March, Ramon; Boukhari, Y.; Mas Serra, Maite; Khader, M.; Ouldali, O.; Regagba, Z.; Tadjeddine, N. 2010-12-15T12:48:41Z http://hdl.handle.net/2117/9986 Title: Abandonment terraced hillside and answer of the fire: some results from Mediterranean old fields Authors: Llovet López, Joan; Ruiz Valera, M.; Josa March, Ramon; Vallejo Calzada, Victoriano Ramón 2010-10-25T17:44:18Z http://hdl.handle.net/2117/9984 Title: Evaluation of two methods for measuring saturated hydraulic conductivity of soils under two vegetation covers Authors: Rubio, Carles Miquel; Josa March, Ramon; Poyatos, R.; Llorens, Pilar; Gallart, Francesc; Latron, Jerôme; Ferrer, Francesc 2010-10-25T17:19:15Z http://hdl.handle.net/2117/9600 Title: Effect of a transient thermal flux on the dormancy of Digitaria sanguinalis seeds Authors: Rubio Esteve, Carlos Miguel; Mas Serra, Maite; Verdú González, Antoni Maria Claret; Gallart González-Palacio, Montserrat; Josa March, Ramon; Ferrer, F 2010-10-09T18:49:53Z http://hdl.handle.net/2117/9425 Title: N-removal from the Liquid fraction of pig slurry in a lab-scale sequencing batch Reactor considering different operational strategies Authors: Magrí Aloy, Albert; Guivernau, Miriam; Prenafeta Boldú, Francesc Xavier; Flotats Ripoll, Xavier 2010-10-06T10:06:01Z http://hdl.handle.net/2117/9372 Title: Sewage sludge application in limestone quarries rehabilitation: Heavy metals in soil, plant and leachates Authors: Balanya Martí, Teresa; Irimia, E.; Llibreria, J.; Milán, D.; Ortiz, Oriol; Pujolà Cunill, Montserrat 2010-10-05T15:33:41Z http://hdl.handle.net/2117/9361 Title: Use of sewage sludge in the restauration of calcareous quarries: Contamination by potentially toxics elements Authors: Pujolà Cunill, Montserrat; Balanya Martí, Teresa; Peiró, J.; Milán, D. 2010-10-05T14:52:05Z http://hdl.handle.net/2117/9332 Title: Efectos de los fangos de depuradoras sobre la fracción húmica de suelos agrícolas Authors: Pujolà Cunill, Montserrat; Saña Vilaseca, Josep; Balanya Martí, Teresa; Romero del Castillo Shelly, Mª del Rosario 2010-10-05T11:28:28Z http://hdl.handle.net/2117/9291 Title: Electrochemical Characterization of a Microbial Fuel Cell (MFC) that Utilizes Cow Manure as Energy Source Authors: Viñas, Marc; Prenafeta Boldú, Francesc Xavier; Flotats Ripoll, Xavier; Gerritse, J 2010-10-04T15:54:03Z
