Academic literature on the topic 'Torre Alfina'

We review the methods based on the measurement of CO2 emissions for the computation of geothermal heat flow, both at a local (hydrothermal sites, a few km2) and regional scale (hundreds km2). At the local scale, we present and discuss the cases of the Latera caldera and Torre Alfina (Italy) geothermal systems. At Torre Alfina and Latera, the convection process sustains a CO2 emission of ~1 kg s−1 and ~4 kg s−1, and heat flows of 46 MW and 130 MW, respectively. At the regional scale, we discuss the case of the central Apennine (Italy), where CO2 mass and enthalpy balances of regional aquifers highlights a wide and strong thermal anomaly in an area of low conductive heat flow. Notably, the CO2/heat ratios computed for the central Apennines are very similar to those of the nearby geothermal systems of Latium and Tuscany, suggesting a common source of CO2-rich fluids ascribed to the Tyrrhenian mantle.

The Castel Giorgio-Torre Alfina (CG-TA, central Italy) is a geothermal reservoir whose fluids are hosted in a carbonate formation at temperatures ranging between 120°C and 210°C. Data from deep wells suggest the existence of convective flow. We present the 3D numerical model of the CG-TA to simulate the undisturbed natural geothermal field and investigate the impacts of the exploitation process. The open source finite-element code OpenGeoSys is applied to solve the coupled systems of partial differential equations. The commercial software FEFLOW® is also used as additional numerical constraint. Calculated pressure and temperature have been calibrated against data from geothermal wells. The flow field displays multicellular convective patterns that cover the entire geothermal reservoir. The resulting thermal plumes protrude vertically over 3 km at Darcy velocity of about7⁎10-8 m/s. The analysis of the exploitation process demonstrated the sustainability of a geothermal doublet for the development of a 5 MW pilot plant. The buoyant circulation within the geothermal system allows the reservoir to sustain a 50-year production at a flow rate of 1050 t/h. The distance of 2 km, between the production and reinjection wells, is sufficient to prevent any thermal breakthrough within the estimated operational lifetime. OGS and FELFOW results are qualitatively very similar with differences in peak velocities and temperatures. The case study provides valuable guidelines for future exploitation of the CG-TA deep geothermal reservoir.

Geothermal energy is a clean resource, which could significantly contribute to the reduction of greenhouse and other gas emissions by replacing fossil fuels for power generation. In many geothermal sites, the resource contains substantial Non-Condensable Gases (NCGs: CO2 and contaminants), whose emissions can be limited to developing power plant schemes suitable for complete resource reinjection. Organic Rankine or other closed-loop cycles are definitely favored in this light. This work investigates a solution for complete NCG reinjection in the liquid-dominated reservoir conditions typical of the Monte Amiata area (Italy), referring to the specific site of Torre Alfina (IT) which presents a specific attractiveness because of its high pressurization. The solution considered avoids flashing the resource and thus presents an appealing environmental performance. The power plant models include energy and exergy balances, as well as exergo-environmental analysis. The overall environmental performance is evaluated by a simplified (preliminary) Life Cycle Analysis (LCA). Different solutions are compared, considering the possibility of sub- or super-critical power cycles.

Founding member of a banking network related to the actual BNP Paribas Group, Meyer Joseph Cahen (1804-1881), adopted the “d’Anvers” when he settled in Paris in 1849. Born in Bonn, of an Ashkenazi family, he made his fortune in the Belgian city to which he associated his name, and he continued his career in France. Owner of Nainville’s castle (Essonne) and of the Petit Hôtel de Villars (Paris), he became a naturalized French citizen in 1865. The next year, he obtained the title of Count, bestowed upon him by the King of Italy Victor-Emmanuel II, thanks to the economic support he offered to the Italian Unification. Nineteen years later, King Humbert I surpassed his predecessor and raised Meyer Joseph’s eldest son, Édouard (1832-1894), to the status of Marquis of Torre Alfina. If his siblings – Emma (1833-1901), Louis (1837-1922), Raphaël (1841-1900) and Albert (1846-1903) – enrooted their pathways in the French capital, the eldest lived between Florence, Naples and Rome: he was one of the great investors involved in the urban renovation of the Italian capital, after the fall of the papacy. In France, as well as in Italy, art, and especially architecture, served to legitimize the recent nobility of a family that wished to express the fullness of its civil rights. As targets of the anti-Semitic press, the Cahen d’Anvers family experienced the consequences of the Dreyfus Affair and the horrors of the racial laws. Before the latter, they adopted what could be defined as a “top-down model of integration”. This thesis focuses on its mechanisms and development. After tracing the patriarch’s origins, it analyses the family’s matrimonial policies and it continues with an exploration of Cahen d’Anvers’ “choices” in the vast field of culture. In their salons, the readers will meet Guy de Maupassant, Paul Bourget, Marcel Proust and Gabriele D’Annunzio, as well as Auguste Renoir and Léon Bonnat. Twelve mansions offered a perfect stage for these intellectual gatherings. As a public manifestation of the family’s economic and social power, the historicist eclecticism of these properties aimed to represent the owners as a new phalanx of the old nobility. While Forge-Philippe’s manor (Wallonia), Gérardmer’s chalet (Vosges) and Villa della Selva (Umbria) expressed a certain openness to the twentieth century novelties, the three residences rented by the family (Hôtel du Plessis-Bellière, Paris; Palazzo Núñez-Torlonia, Rome; Château de la Jonchère, Yvelines) and the two properties of Meyer Joseph, as well as Rue de Bassano’s mansion (Paris) or the castles of Champs (Seine-et-Marne), Bergeries (Essonne) and Torre Alfina (Latium) dressed up their nineteenth century spaces with Ancien Régime motifs. Thanks to their historical knowledge and taste, the architects Destailleur, Giuseppe Partini and Eugène Ricard, as well as the landscapers Henri and Achille Duchêne, were able to bend the Middle Age, the Renaissance and the 18th century’s “grammars” to their patrons’ taste and ambitions.

Populism represents the greatest political challenge to Western democracies since World War II. The electoral successes of populist parties and actors, Brexit, the presidency of Donald Trump or campaigns against containing the coronavirus pandemic are expressions of this phenomenon, in which the electorate is mobilised against supposed elites. The revised and expanded handbook Political Populism offers a comprehensive theoretical and empirical introduction to the causes and effects of political populism, especially in the democratic systems of Europe, but also in North and South America. It focuses on explaining populism as a consequence of a legitimation crisis of the representative system as well as on the controversies and limitations in the current academic debate. Drawing on political and communication science, the book also offers a comprehensive analysis of the effects of populism on various policy areas, such as environmental, health and economic policy.

With a welcome expansion in cases and policy fields, the second edition of Political Populism: Handbook on Concepts, Questions and Strategies for Research brings together scholars from a range of disciplines to reflect on the fundamental challenge populism poses today. This Handbook is essential to every reader who wants to understand where populism comes from, how it manifests and how it influences policies, political actors and the very institutions that make democracy. Theoretically sophisticated, substantiated in its content yet approachable for the interest reader, this Handbook marks an important step in the appreciation of the complexity and consequences of this global phenomenon. Annika Werner, Australian National University Two decades of turbulent political history show that populism is here to stay, and to shape politics for a long time to come. It is considered a serious threat to traditional democratic institutions. That’s why political and communication scientists have massively engaged in studying it, in explaining it, in analyzing its features and implications. Among the several recent scholarly productions, this Handbook is perhaps the best tool put in the hands of all those who want to get a multi-dimensional yet comprehensive understanding of political populism as it is developing in Europe and in the Americas. Definitely a must-have book! Gianpietro Mazzoleni, Università di Milano, Italy This highly readable and detailed Handbook synthetizes a wealth of accumulated and innovative research on contemporary populism in Europe and the Americas. Drawing the insights of a distinguished group of specialists, the volume presents a comprehensive and updated view of the vibrant field of populist studies. Its four sections and thirty-four chapters provide stimulating perspectives on the theory, politics, and communicational dimensions of populism as well on emerging areas of research. A must read for anyone interested in understanding the complexities of a phenomenon that is likely to remain an enduring and unsettling presence in the political life of XXI century democracies.
