A False Sense of Protection: Recreational Uses and Illegal Behavior in a Mediterranean Marine Protected Area and Implications for Management.
2019
Over the last 35 years, at both the European and the Italian level, great efforts have been made to increase the number of Marine Protected Areas (MPAs): they are considered an effective tool for protecting oceans and biodiversity. In recent years, MPAs have become more than simply tools to improve marine conservation. In fact, their management agencies are actively involved in the sustainable development of nearby communities through the promotion of recreational activities (boating, snorkeling, diving). Even if the recreational uses of the marine environment are generally considered benign, they can potentially be highly detrimental for species and their habitats. As a result, these activ…
La desigualdad económica regional en América Latina (1895-2010)
2020
En este artículo se analiza por primera vez el crecimiento y la evolución de la desigualdad regional a lo largo del proceso de desarrollo económico de nueve países de Latinoamérica (Argentina, Bolivia, Brasil, Chile, Colombia, México, Perú, Uruguay y Venezuela) entre 1895 y 2010. Para ello, en primer lugar se verifica la presencia de un proceso de beta-convergencia entre los países latinoamericanos para la totalidad del periodo. No obstante, se muestra cómo este proceso fue especialmente intenso durante los periodos en los que los diferentes Estados implementaron políticas activas de desarrollo (ISI) que favorecieron la convergencia entre las regiones de un mismo país. En segundo lugar, se …
Modeling of retrograde diffusion zoning in garnet: evidence for slow cooling of granulites from the Highland Complex of Sri Lanka
2003
¶Diffusion modeling of zoning profiles in garnet rims from mafic granulites is used to estimate cooling rates in the Proterozoic basement of Sri Lanka, which represents a small, but important fragment of the Gondwana super-continent. Metamorphic peak temperatures and pressures, estimated with two-pyroxene thermometry and garnet–clinopyroxene–plagioclase–quartz (GADS) barometry, yield 875±20 °C and 9.0±0.1 kbar. These peak metamorphic conditions are slightly higher than results obtained by garnet-biotite Fe–Mg exchange thermometry of 820±20 °C. Reset flat zoning profiles were observed in most garnets. Only narrow garnet rims touching biotite exhibit retrograde zoning in terms of Fe and Mg ex…
Acclimatization, distribution and potential economic use of Argania spinosa (Sapotaceae) in southern Italy
2021
The authors report updated notes on the acclimatization, distribution, areas suitable for cultivation and, potential use of Argania spinosa (Sapotaceae) in southern Italy. Based on observations carried out on the plants cultivated in Bari and the Botanical Garden of Palermo, and on ecological requirements of the species it is possible to consider A. spinosa as a woody species easily adaptable to the coastal climate of southern Italy.
A geophysical and geochemical approach for seawater intrusion assessment in the Acquedolci coastal aquifer (Northern Sicily)
2007
Vertical electrical sounding (VES’) surveys and chemical analyses of groundwater have been executed in the coastal plain of Acquedolci (Northern Sicily), with the aim to circumscribe seawater intrusion phenomena. This urbanized area is representative of a more general problem interesting most of Mediterranean littoral areas, where intensive overdraft favors a heavy seawater intrusion through the coastline. Aquifer resistivity seems decisively to be conditioned by the chlorine and magnesium content in the main aquifer of the region. Schlumberger VES’, together with piezometric and chemical–physical information of groundwater, allowed us to perform hydrogeological and geophysical elaborations…
Initial layout of DEMO buildings and configuration of the main plant systems
2018
Abstract The realization of a Demonstration Fusion Power Reactor (DEMO) to follow ITER, with the capability of generating several hundred MW of net electricity and operating with a closed fuel-cycle is viewed by Europe and many of the nations engaged in the construction of ITER as the remaining crucial step towards the exploitation of fusion power. The development of suitable configurations of plant systems inside the tokamak building to allow for the various maintenance operations and to meet the numerous system operating functions and safety requirements is one of the initial priorities. A task to establish an initial layout of the DEMO buildings and the integration of the main plant syst…
Les terroirs viticoles : une méthodologie de zonage en fonction du sol
2010
Terroir is a key-concept in viticulture that is more and more widely recognized to explain variations in wine quality and wine style. Terroir refers to an area and thus possesses a geographical dimension. Hence, zoning of viticultural terroir is necessary. This paper addresses soil related aspects of terroir zoning. The first step of the zoning process is a clear identification of the objectives that are being pursued: demarcation of production areas, the adaptation of the viticultural management practices to variations in soil types or the protection of viticultural landscapes. The second step is the definition of a scale adapted to the objectives. The precision of the zoning increases wit…
Garnet as a monitor for melt–rock interaction: Textural, mineralogical, and compositional evidence of partial melting and melt‐driven metasomatism
2021
International audience; In this study, we focus on a partially melted garnet-bearing granulite from the Salvador–Esplanade Belt (Salvador da Bahia, Brazil), and examine the behaviour of major and trace elements during partial melting and melt-driven metasomatism. Phase equilibria modelling and U–Th– Pb geochronology show that the sample underwent partial melting during the heating segment of the decompression path from ~1.2 GPa and 675–700° C to ~0.8 GPa and 790°C at c. 2.06 Ga. During the final stage of decompression, from 0.8 to ~0.5 GPa, physical segregation of melt resulted in the establishment of chemical potential gradients and mass transfer between the host granulite and the leucosom…
GIOIOSA MAREA. Ultimi tentativi di accostamento e di combinazione tra le pratiche di zoning e le strategie di visioning
2022
La rielaborazione del Piano Regolatore Generale di Gioiosa Marea (Me) è quasi una situazione tipo tra le vicende legate alla ex L.R.71/78. Gioiosa Marea, infatti, è uno dei tanti Comuni siciliani che hanno avuto un lungo e travagliato iter redazionale, sia dal punto di vista tecnico-gestionale, quanto dal punto di vista politico- amministrativo.
