Multidisciplinary approach for the sustainable utilization of medium-low temperature geothermal resources
No full textA growing interest in the applications of the medium-low temperature geothermal resources can be observed, but often a reference frame in this field does not exist. Different backgrounds are involved in the design and optimization of geothermal projects: Earth Sciences, Engineering, Economics, Environmental Impact. In the practice one aspect often tends to take priority on the others. In this work firstly the elements for a methodological interdisciplinary framework for geothermal projects analysis are given. A clear frame of the state of the art and possible technical-scientific developments are illustrated.
The necessity of an "integrated" interdisciplinary approach is underlined, with reference to several case studies. The geothermal potential evaluation tasks and methods are illustrated, and some outlines for an assessment oriented to the resource utilization are described. The sustainability of geothermal projects is analysed under different perspectives and criteria.
The main technological issues of geothermal binary cycle power plants are discussed (mainly for small power size), together with technological solutions. The concept of upper limit to the extraction rate is introduced, with reference to an equilibrium point between power production and resource depletion. Direct heat uses are also briefly described and the common issues related to environmental impact and resource durability are then discussed, with a particular focus on the scaling phenomena and the reinjection strategy. An innovative solution for geothermal power production (SBES) is described: the application of the heat pipe principle, in the CLTPT concept, for power production purposes is proposed.
The numerical simulation of geothermal reservoirs is an important instrument for the synthesis between the different backgrounds involved in the geothermal energy study. General aspects and its potentialities (historical data matching and forecast of future utilization scenarios) are illustrated. Several numerical models from scientific literature are reviewed (about 21 geothermal fields and related 24 numerical models). The reservoir models of Momotombo (Nicaragua) and Sabalan (Iran) have been realised from literature data and widely discussed. One original model, Monterotondo Marittimo - Torrente Milia (Italy) has been realised in a very multidisciplinary framework and it is also presented. Different utilization scenarios for the case studies are analysed and their sustainability level is discussed.
A purely economic approach is considered to be counter-productive for geothermal utilizations, so the thermoeconomic analysis is here applied to geothermal power plants. Momotombo case study and other small size power plants are analysed in order to estimate their thermoeconomic sustainability (exergy balances and cost items are evaluated). The current Italian geothermal energy market situation is briefly described, in relation to the ORC technology diffusion. The small size plants technological and environmental issues treated in this work are then linked to the current way of diffusion in the Italian market.
The outlines coming from the global work of analysis are organised in order to give the main features of the proposed methodological approach. The multidisciplinary perspective is reviewed and extended in order to optimize the sustainability of the projects (environmental impact reduction, resource durability)
Two Batch Search With Lie Cost
No full textAhlswede R, Cicalese F, Deppe C, Vaccaro U. Two Batch Search With Lie Cost. IEEE TRANSACTIONS ON INFORMATION THEORY. 2009;55(4):1433-1439.consider the problem of searching for an unknown number in the search space U = {0, ..., M -1}. q-ary questions can be asked and some of the answers may be wrong. An arbitrary integer weighted bipartite graph Gamma is given, stipulating the cost Gamma(i.j) of each answer j not equal i when the correct answer is i, i.e., the cost of a wrong answer. Correct answers are supposed to be cost-less. It is assumed that a maximum cost e for the sum of the cost of all wrong answers can be afforded by the responder during the whole search. We provide tight upper and lower bounds for the largest size M = M(q, e, Gamma, n) for which it is possible to find an unlinown number x* is an element of U with n q-ary questions and maximum lie cost e. Our results improve the bounds of Cicalese et al. (2004) and Ahlswede et al. (2008). The questions in our strategies can be asked in two batches of nonadaptive questions. Finally, we remark that our results can be further generalized to a wider class of error models including also unidirectional errors
Il "Realismo Costruttivo" per una banca moderna
No full textUna introduzione storica di Valerio Castronovo sulle origini della Banca Nazionale del Lavoro apre un volume monografico dove vengono raccontate le esperienze urbanistiche della Roma degli anni Venti: come Marcello Piacentini e Giuseppe Vaccaro pensarono via Veneto, via Bissolati e via Barberini, il palazzo della BNL, il MInistero delle Corporazioni, l'Hotel Ambasciatori e in genere l'area attorno a Termini. Il realismo costruttivo si propagava e la Banca ebbe un ruolo centrale in quanto commissionò numerose architetture. I saggi ne ripercorrono le vicende urbanistiche, architettoniche, decorative dopo l'avvenuto restauro
First record of Pachygrapsus transversus (Gibbes, 1850) (Brachyura, Grapsidae) in Italian waters.
No full textPachygrapsus transversus (Gibbes, 1850) is reported for the first time from Italian waters. This crab was collected at Ustica Island and at several other localities on NWSicily (southern Tyrrhenian Sea) on vermetid reefs, an intertidal habitat frequent in the sampling area. P. transversus, whose distributional range covers the warm and warm-temperate areas of the eastern and western Atlantic and the eastern Pacific, was already known from the eastern Mediterranean since the 1920s; prior to this paper it was recorded in the western Mediterranean only in 1980 and 1994 with very few specimens.
There are no data to ascertain the origin of the Sicilian population, i.e., natural or ship-mediated diffusion; either is considered possible in theory. Yet, the presence of young specimens (around 5 mmcarapace length) and ovigerous females, as well as the numerical abundance at one of the Sicilian sites, suggest that the NW Sicily population is stable and well acclimatized
Le tecnologie meccaniche ambientalmente compatibili per l’estrazione dei minerali
No full textI metodi di separazione fisici consentono di estrarre dalle rocce i minerali necessari all’industria ed in particolare all’industria “high tech” e a quelle che operano per la conversione ecologica. I rifiuti industriali e soprattutto i minerari ospitano minerali che contengono inquinanti che se estratti possono soddisfare le esigenze di approvvigionamento dell’industria, ma anche di procedere alla riqualificazione ambientale delle loro aree di stoccaggio. I materiali sterili una volta privati dai minerali e metalli di interesse minerario perdono il loro carico inquinante e possono essere reimpiegati sia a fini industriali (ad es. feldspati e quarzo) sia come aggreganti nell’edilizia. Il miglioramento tecnologico nelle
strategie di separazione consente di applicare in cave e miniere i principi di economia circolare, non a caso oggi si tende a estrarre i minerali di interesse anche dai rifiuti stoccati nelle discariche delle ex aree estrattive, che per motivi tecnologici nel passato sono stati stoccati nonostante le elevate concentrazioni di risorse. Questa strategia, fortemente incoraggiata dalla UE, consente di recuperare suolo e di agire su prodotti già in pezzatura utile per la loro ottimizzazione ai fini estrattivi. Questo settore è in espansione in quanto l’Europa sta promuovendo piani di autosufficienza nell’approvvigionamento delle risorse minerarie con particolare attenzione alle risorse strategich
