Propuesta de microrreservas vegetales. Una alternativa para la conservación de líquenes en la comunidad Valenciana.
2001
ATIENZA, V., SEGARRA, J. G & LAGUNA, E. 2001. Plant micro-reserves proposal, as an alternative for lichen conservation in the Valencian Community. Bot. Complutensis 25: 115-128. In the scope of the Valencian Community 6 areas are proposed as lichenological flora micro-reserves, two of them are located in the Alicante province: 1.Villena, Cabezo del Chocolaino and 2. Xàbia, Cabo de San Antonio, Morro dels Cocons, two in the Castellón province: 3. Pina de Montalgrao. Santa Bárbara de Pina and 4. Illes Columbretes. Illa Grossa and two in the Valencia province: 5. Puebla de San Miguel. Cerro Calderón and 6. El Saler. Pujol Nou. Location, description and a list of the most interesting lichen…
Evaluación multicriterio de políticas de uso y gestión de recursos naturales
2014
The purpose of this work is show the characteristics of different environmental economic assessment methodologies, and exposes a case study where possible alternatives addressed to reduce the contamination of a bay with multicriteria approach are evaluated. The results obtained show the effectiveness of multicriteria analysis to evaluate the alternatives for solution of contamination problem in a bay. Economic evaluation of the contamination effects integrated to the environmental, social and economic dimensions through multicriteria techniques allows an alternative planning to solve the environmental problem studied, providing the right decision.
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.
Gas chromatography-mass spectrometry characterization of the varnish and glue of an ancient 18th century double bass.
2007
A GC–MS investigation is conducted on the double bass “Panormus”, property of Conservatorio di Musica “Vincenzo Bellini” in Palermo. The most important components of the varnish (fatty acids) and of the glue (proteinaceous amino acids), with which the musical instrument was treated in the past, are determined. The analyses are carried out by prior derivatization of fatty acids by acidic methanol and of amino acids by acidic methanol and trifluoroacetic anhydride (TFAA). Analytes identification is achieved by direct comparison with several reference materials and the use of a digitized library.

Voltammetric determinations of platinum and rhodium in particulate of Palermo (Italy) area
2012
Traffic has an important impact on the air quality which affects both the environmental and human health. Since the introduction of PGE-containing catalytic converters, a number studies have been undertaken to determine the effects of PGE emissions on human and to environment. This requires the development of good analytic methods to measure Pt and Rh concentrations in environmental matrices, as well to estimate background concentrations. In this paper are presented the results concerning Pt and Rh concentrations in PM10 samples collected at five stations within the urban area of Palermo. The highest mean values (Pt= 13 pg/m3, Rh=9.8 pg/m3) were recorded at an urban station, and the lowest …
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.
