Analysis of 7Be and 210Pb concentration and 7Be/210Pb activity ratio in ground level air in Palermo (Italy)
2019
A series of measurements of particulate samples collected on paper filters in Palermo (Italy) during 1995–2005 has been performed to detect 210Pb air activity concentration and, along with previous similar data on 7Be, to evaluate their activity ratio. Average values for the daily activity concentrations of 7Be and 210Pb are found to be 4.7 and 0.6 mBq/m3 , respectively, 9.8 being the average activity ratio. Data confirm a seasonal behavior for both radionuclides. A correlation between 7Be and 210Pb air activity concentrations seems to exist, despite their different origins. The time behaviors of both 7Be and 210Pb air concentrations and 7Be/ 210Pb activity ratio have been compared with som…
Pre- and syn-eruptive geochemistry of volcanic gases from Soufriere Hills of Montserrat, West Indies
1998
International audience; Soufriere Hills fumaroles contained magmaderived volatiles before and during the eruption initiated in 1995 but also preserved a typical and quite steady hydrothermal coinposition. Chemical changes due to increased boiling and a greater input of oxidizing magmatic gas occurred only at Galway's Soufriere, the most active fumarolic field. Hydrothermal buffering of the fumaroles has been favoured by their remote location (!-2 km) froin the eruptive vents and by a preferential degassing of the uprising magma through intrusive conduits under the crater. High temperature (720øC) gas collected froin the extruding lava dome in Feb. 1996 was chemically and isotopically repres…
Volatile Profiles of Emissions from Different Activities Analyzed Using Canister Samplers and Gas Chromatography-Mass Spectrometry (GC/MS) Analysis: …
2017
The objective of present study was to identify volatile organic compounds (VOCs) emitted from several sources (fuels, traffic, landfills, coffee roasting, a street-food laboratory, building work, indoor use of incense and candles, a dental laboratory, etc.) located in Palermo (Italy) by using canister autosamplers and gas chromatography-mass spectrometry (GC-MS) technique. In this study, 181 VOCs were monitored. In the atmosphere of Palermo city, propane, butane, isopentane, methyl pentane, hexane, benzene, toluene, meta- and para-xylene, 1,2,4 trimethyl benzene, 1,3,5 trimethyl benzene, ethylbenzene, 4 ethyl toluene and heptane were identified and quantified in all sampling sites.
Biostratigraphy, Chronostratigraphy and Paleonvironmental Reconstruction of the Palermo Historical Centre Quaternary succession
2016
Marine deposits from the Palermo Plain were historically relevant for the Quaternary Period definition. Here we show lithostratigraphic, biostratigraphic and chronostratigraphic data collected on three boreholes in the Palermo historical centre that recovered 36.8, 42.0 and 52.0 metres of sediments overlaying the Numidian Flysch. Marine sedimentary sequences span from the Calabrian Stage (calcareous nannofossil Zone MNN 19d) to the Middle Pleistocene (dominance of medium-sized gephyrocapsids within the MNN 19f Zone) and also include a short Holocene depositional event. Calcareous nannofossil, benthic and planktonic foraminifera assemblages point to a shallow coastal environment, possibly < …
15 Minute City Concept and Palermo Case Study
Sustainable urban mobility models and decarbonization in transportation have been discussed globally for decades. Yet the problem is not just decarbonization and the solution is not limited to green technology alone. Particularly, Covid-19 brought to light other important and ingrained problems of cities such as inequality of accessibility, the marginalization of some urban, peri-urban, rural territories and the emergence of social exclusion. In order to find a way out from these problems, practical, easily accessible, comfortable, and cheap alternatives should be provided to citizens and the use of private vehicles should be minimized. However, no matter how many alternative transportation…
15 Minute City Concept. A Glance at the Palermo Case Study
2022
Giving people opportunities for green technology and offering them new transportation modes are not sufficient methods for the transition to a sustainable mobility model. With the increasing importance of time, minimizing the daily travel time of people seems to be one of the crucial steps to be taken. 15 Minute City is one of the latest popular concepts assuring to reduce daily travel time and improve quality of life while enhancing environmental conditions. This paper will have a look at the concept regarding the case study of Palermo, one of the cities with the most intense traffic problems in Europe.
Bagheria e l’amministrazione Cinque Stelle (Bagheria and Five Star local government)
2016
Il paper studierà il caso di Bagheria in provincia di Palermo, Comune amministrato da Patrizio Cinque sindaco del Movimento 5 Stelle da giugno 2014. A partire dall’analisi degli elementi che ne hanno contribuito a determinare il successo elettorale (connessi allo scenario e alla campagna elettorale), si prenderanno in considerazione le peculiarità dell’amministrazione locale pentastellata nei suoi primi due anni, approfondendo in particolare la relazione tra portavoce, attivisti ed elettori prima e durante il mandato, i rapporti con gli altri Meetup locali e nazionali, le strategie comunicative, i progetti, la capacità di resistenza agli scandali che hanno colpito l’assessore all’urbanistic…
Pozos y mafiosos. La inacabada transición del mercado del agua a la gestión colectiva en el Palermo sel siglo XX
2018
La creación de los consorcios de riego, en la primera posguerra, revolucionó los equilibrios sociales e hidráulicos de las regiones citrícolas de Palermo (Italia). En este artículo, a través de fuentes primarias, se analizan las relaciones conflictivas entre los agricultores usuarios, los nuevos y controvertidos organismos de gestión colectiva, los propietarios de pozos, acusados de dominar el mercado de las aguas, y los distribuidores, enjuiciados por pertenecer a la mafia en los años fascistas.
