Marsala. Verso il primo piano urbanistico di nuova generazione
2022
Il saggio illustra i risultati preliminari delle attività di analisi che si stanno conducendo verso la redazione del Piano Urbanistico Generale (PUG) nel quadro della riforma del governo del territorio che la Regione Siciliana ha avviato con la Legge regionale 19 del 2020. Dopo una lettura qualitativa e quantitativa della crescita urbana negli ultimi decenni, sono delineati alcuni caratteri peculiari del territorio oggetto di studio, ed evidenziati alcuni processi tendenti a compromettere una equilibrata organizzazione del territorio. Infine, vengono indicati alcuni orientamenti strategici che il nuovo piano è destinato ad assumere, alla luce di alcune questioni ambientali che solo una corr…
Consumo di suolo e sviluppo locale sostenibile
2010
The research examines the issue of waste of land in metropolitan area of Palermo and offers a description of the current situation through a systematic data. Target is knowledge of waste of land, to develop indicators of the phenomenon and to develop appropriate reflection on the effects of environmental and landscape change, suggest urban policies for sustainable local development.
Advanced Formation Fluid Evaluation While Drilling with a New Heavy Gas Detector
2012
In this paper, a chromatograph which exploits the benefits of FID technology optimized for the high resolution detection of heavier hydrocarbon gas components is described. The components analyzed span from n-hexane to toluene. Flame Ionization Detector (FID) technology is not new to gas detection on the field, however it had never been applied to the detection of gases heavier than n-pentane. The instrumentation has been installed and run on a number of wells in different fields and countries, and it has operated as a complement of an advanced surface logging system for a period of two years. Unlike other technologies presently utilized for this scope, this system reduces dedicated equipme…

Andamento stagionale del flusso di emissione di CO2 dal suolo in risposta al contenuto di umidità all'interno di un agroecosistema mediterraneo
2014
Total soil respiration as the sum of two biotic component, autotrophic and heterotrophic respiration, is influenced by various environmental factor, in particular soil temperature and soil moisture. In arid and semi arid regions, soil moisture is a major driver of soil respiration during periods of drought stress. Hence, the aim of this work was to evaluate the effect of soil moisture on soil CO2 efflux. Measurements were made every two weeks between January 2008 and June 2010 using a portable soil respiration instrument fitted with a soil respiration chamber (IRGA) CIRAS 1 (PP Systems, Hitchin, UK).The Simultaneously with soil respiration measurements, soil temperature (T) and soil volumetri…
The influence of pulsed redox conditions on soil phosphorus
2010
Abstract. The effects of eleven pulsed reduction-oxidation cycles (20 and 2 days, respectively) on soil phosphorus (P) dynamics are compared for 12 soils having contrasting properties and overfertilised with respect to P. Incubation conditions simulated transient waterlogging of the soil profile and involved repeated sampling and analysis of both the solution and solid phase P forms. An initial increase in P concentration occurred upto and including the fourth full cycle was followed by a sharp decline in concentration for all but one soil. Accompanying changes in the main extractable forms of P, which appeared to be cumulative, could be summarised as a general decline in the organic P frac…
