Antiguos puertos e islas en el litoral andaluz: cartografía, toponimia e historia
2003
Se trata de recordar y agradecer las enseñanzas del Dr. Rosselló y aplicarlas a las costas andaluzas, de cuyas variadas formas llaman la atención los procesos de aterramiento de la parte atlántica, donde hay lugares cuya situación actual no responde a su topónimo (Isla Cristina, San Juan del Puerto...). A estudios anteriores, añadimos noticias históricas y trazados de mapas, que señalan una rápida evolución, referido principalmente a tres ámbitos. La desembocadura del Guadiana, que pasa en época histórica de barras arenosas e islas a zonas cultivadas y urbanizaciones de playas; el antiguo estuario del río Piedras, con puertos aún en el XIX, que sustenta hoy marismas, naranjales y cultivos d…

Metals distribution in the organic and inorganic fractions of soil: A case study on soils from Sicily
2005
The content of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, has been determined in the organic and inorganic fraction of eight soil samples from Sicily. A modified type-Tessier sequential extraction procedure has been used to recognize metals in five different fractions categorised as follows: (a) exchangeable metals, (b) metals bound to carbonates, (c) metals bound to iron and manganese oxides, (d) metals bound to organic matter, and (e) metals in residual fraction. The mineralogical composition of soils samples was characterized by X-ray diffraction. Humic substances were extracted by means of an alkaline extraction procedure. It has been found that both the mineralogical composition and the di…
New insights in the metabolic behaviour of PAO under negligible poly-P reserves
2017
[EN] In a previous study the authors confirmed the ability of PAOs to perform GAO metabolism in short-term experiments. However, what happens when PAOs are exposed to poly-P shortage for an extended period of time? The answer to this question was the aim of this work from a macroscopic and microscopic point of view. Therefore, the poly-P was removed from a PAO enriched SBR and maintained without poly-P during five solid retention time. The PAOs were found to quickly change their metabolism to a clear GAO performance and remained without GAO colonization for the entire experimental period, even though GAO was present (around 5%) at the beginning of the experiment. Unlike the results obtained…
