Paesaggio, urbanistica e ambiente: un patto per il governo del territorio
2012
La consolidata separazione tra Urbanistica e Paesaggio poggia le sue fondamenta su una precisa visione del paesaggio in termini prettamente estetici e culturali. La Vas, un nuovo strumento individuato dalla Comunità Europea per integrare considerazioni di natura ambientale nei piani e nei programmi e migliorarne la qualità decisionale complessiva, riconduce l’attenzione dei diversi operatori alle componenti strutturali del paesaggio. Per questa ragione, la Vas, se ben costruita, può dispiegare appieno le sue reali potenzialità, anche nel nostro Paese, ed essere considerata la “cerniera” trasversale che consenta l’integrazione, nel piano, della sostenibilità ambientale, economica e sociale.

Effect of pH and nitrite concentration on nitrite oxidation rate
2011
The effect of pH and nitrite concentration on the activity of the nitrite oxidizing bacteria (NOB) in an activated sludge reactor has been determined by means of laboratory batch experiments based on respirometric techniques. The bacterial activity was measured at different pH and at different total nitrite concentrations (TNO 2). The experimental results showed that the nitrite oxidation rate (NOR) depends on the TNO 2 concentration independently of the free nitrous acid (FNA) concentration, so FNA cannot be considered as the real substrate for NOB. NOB were strongly affected by low pH values (no activity was detected at pH 6.5) but no inhibition was observed at high pH values (activity wa…
International Legal Approaches to Waste Water Discharges. Opening speech
2002
En este discurso inaugural, realizo una introducción a la frustrante situación jurídica en la que se encuentran las descargas de aguas residuales a nivel internacional. Las descargas de aguas residuales son la mayor fuente de contaminación marina y, en consecuencia, ellas representan el mayor riesgo actual para la protección del medio ambiente marino. In this opening speech, I make an introduction to the disappointing legal situation of waste water discharges at international level. Waste water discharges is the main source of marine pollution and, therefore, they represent the major current risk to the protection of the marine environment.
El contacte entre la Ribera del Xúquer i els raiguers de les Muntanyes de Carcaixent
1985
Cuando el río Xúquer llega a la Ribera, deja el encajamiento montañoso y forma un cono aluvial que ent ra en contacto con los piedemontes originados por los relieves emergidos en las cercanías de la llanura de inundación, apareciendo unas zonas deprimidas en el punto de contacto de las dos formaciones por los perfiles opuestos que presentan. Además, el contacto no es estable debido a la diferente velocidad de crecimiento en altura, y en consecuencia los depósitos fluviales conquistan poco a poco las tierras de piedemonte y por lo tanto, la zona deprimida se aleja cada vez más del río. En segundo lugar, los núcleos de población, que hace muchos años estaban al margen de las inundaciones por …
Identifying clouds over the Pierre Auger Observatory using infrared satellite data
2013
We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud. identifications resulting from our method to those obtained by the Central Laser Facility of the Auger Observatory. Using our new method we can now develop cloud probability maps for the 3000 km(2) of the Pierre Auger Observatory twice per hour with a spatial resolution of similar to 2.4 km by similar to 5.5 km. Our method could also be applied to monitor cloud cover for other ground-based observatories and for space-based observatories. (C) 2013 Elsevier B.V. All rights reserved.
Harnessing the biodiversity value of Central and Eastern European farmland
2015
A large proportion of European biodiversity today depends on habitat provided by low‐intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly the central and eastern new member states have retained relatively large areas of species‐rich farmland, but despite increased investment in nature conservation here in recent years, farmland biodiversity trends appear to be worsening. Although the high biodiversity value of Central and Eastern European farmland has long been reported, the amount of research in the international literature focused on farmland biodiversity in this region remains comparatively ti…
L’agricoltura biologica e lo sviluppo del territorio di qualità: un caso studio siciliano
2012
Farming grows into an intense relationship with the territory; local products are the expression of local culture and environment. Territory itself is an attribute of the goods; at the same time, the consumer becomes a user of the same territory. It is possible to turn on a strategy that considers the territory a source of competitive advantage. Organic farming is paradigmatic of the relationship between agricultural production and the territory that is based on the pursuit of harmonious interaction between human activities and the environment

Identification and quantification of microbial populations in activated sludge and anaerobic digestion processes
2014
Eight different phenotypes were studied in an activated sludge process (AeR) and anaerobic digester AnD) in a full-scale wastewater treatment plant by means of fluorescent in situ hybridization (FISH) and automated FISH quantification software. The phenotypes were ammonia-oxidizing bacteria, nitrite-oxidizing bacteria, denitrifying bacteria, phosphate-accumulating organisms (PAO), glycogen-accumulating organisms (GAO), sulphate-reducing bacteria (SRB), methanotrophic bacteria and methanogenic archaea. Some findings were unexpected: (a) Presence of PAO, GAO and denitrifiers in the AeR possibly due to unexpected environmental conditions caused by oxygen deficiencies or its ability to survive …
