Experimental tests about the cooling/freezing of the molten salts in the receiver tubes of a solar power plant with parabolic trough
No full textIn 2003 ENEA realized the PCS experimental Facility at Casaccia Research Centre (Rome, Italy), in order to test in real operating conditions the components of a parabolic trough solar plant, and to evaluate the technical feasibility of using the solar molten salts mixture (60% NaNO3, 40% KNO3, melting point 220÷240°C) in such a type of plant. ENEA also had the need to assess the behaviour of the solar receiver tubes during abnormal operating situations (wrong operation, pump block, power failure, etc.), when a block of the circulation of the molten salts may occur and cause the cooling or, worse, the freezing of the salts mixture inside the pipes. Some experimental tests have been performed, aimed to examine what happens in such a cases. In fact, without quick maneuvers to restart the circulation of the molten salts or to readily empty the receiver tubes, the molten salts contained in them may cool down to temperatures near/below the solidification. In this report are shown the results of the experimental tests carried out on the receiver tubes of the PCS Facility by cooling the process fluid down to temperatures near or below its freezing point. The tests show that the solidification of the salts does not damage the components of the plant but it is manageable and reversible, provided you apply the correct procedures. © 2017 Author(s)
ALKYLARYLKETONE HOMOLOGOUS SERIES FOR DETERMINATION OF KOVATS RETENTION INDICES WITH RP-HPLC USING ACETONITRILE/WATER SYSTEM
Full text linkSome factors such as the changes of the stationary phase, temperature, pH-value, mobile-phase composition and flow rate play a crucial role in effecting the sensitivity of retention times in high performance liquid chromatography (HPLC) system. Utilizing a retention index system is one of the methods to minimize those effects. Besides the mentioned factors, dead-time influences on determining the retention index as well. In comparison with Gas Chromatography (GC), the retention Index determination method in HPLC is still widely discussed, due to the difficulty of utilizing n-alkane as standard. In addition, the solutes in HPLC interact with the mobile-phase, thus the retention behavior also depend on the mobile-phase. Actually, It is difficult to use n-alkanes in HPLC as standards in case of some considerable problems, due to they are very non polar but also large retention times which lack of chromophores. Therefore, using n-alkane in routine analysis could be inconvenient. In comparison with n-alkanes, the alkylarylketones homologous series are stable compounds, commercially available and easily detected by a UV detector. This paper introduces Determination of Kovats Retention Index in the HPLC using Alkylarylketone homologous series and then is connected with n-alkane as a frame of reference. Steroids were used as test substance for calculating Kovats retention index values in acetonitrile/water system.
Keywords: Kovats Retention Index, RP- HPLC, n-alkane, alkylarylketon
Ius soli: qualche precisazione di metodo in materia di diritti di cittadinanza e diritti della cittadinanza
No full textThe Author analyses, among many possible meanings of citizenship, two types which had a part in the process of modern State building: citizenship is sometimes a relationship between the individual and the sovereign, sometimes consciousness of a collective membership. Both meanings have a link with the sovereignty and the process of modern State building. After the “great Neutralisation” of the Nineteenth Century, some reflections are developed about the relationship between citizenship and sovereignty in the Twentieth Century. Finally, the Author emphasizes the necessity of a statute that sets the requirements needed to become a citizen in order to pacify the conflicts of multicultural societies
The Italian Supreme Court Joint Sections set forth the interpretative underpinnings of the "Gelli-Bianco" law: varying degrees of guilt aimed at limiting medical liability, article 2236 C.C. makes a comeback
Full text linkThe article’s author has sought to summarize the regulatory and legal evolution of accidental criminal liability of doctors starting from earliest positions up until the enactment of the Gelli-Bianco law. An in-depth analysis is laid out based on the Italian Supreme Court Joint Sections ruling n. 8770/2018 (so-called Mariotti decision). The author has also elaborated upon the notion of varying degrees of guilt, which was taken out of the law’s wording, to be later reintroduced as a concept by judicial interpretation. It is worth noting that Article 3 of the Balduzzi decree, article 590 sexies of the Italian Criminal Code and the reference to article 2236 of the Civil Code reflect an awareness on the part of legislators that medical liability needs to be limited. Clearly, the approach based on lawfulness alone, which protects from liability physicians that have adhered to guidelines, has been dismissed, superseded by the notion of minor fault. Nonetheless, the new legislation, in the author’s estimation, constitutes a standard particularly ill-suited to modern medical practice, which has a high degree of complexity. The author concludes that it might be worth considering a more balanced alternative: getting back to the notion of fault, considering minor fault relevant, rather than major fault
La corte costituzionale legittima le misure di contenimento del covid-19, ma la motivazione soddisfa solo in parte
No full textL’Autrice si sofferma sull'assimilabilità dei d.P.C.m. attuativi delle misure di contenimento e gestione dell’emergenza sanitaria da COVID-19 agli atti necessitati d’urgenza ed evidenzia il carattere solo in parte soddisfacente degli argomenti impiegati dalla Corte costituzionale per il rigetto delle questioni di legittimità costituzionale sollevate avverso i decreti-legge disciplinanti tali misure.The Author dwells on the comparability of the d.P.C.m. taken to implement the containment measures and to manage the COVID-19 health emergency to the urgent and needed acts. The Author also highlights the only partially satisfactory nature of the arguments set out in the judgment that rejected the issues of constitutionality raised against the decree-laws adopted in order to regulate such measures
Due interpreti dell'Etica di Spinoza: Harold H. Joachim e Karl Jaspers
No full textIn this book, the author takes into consideration two crucial episodes of the history of the interpretations of Spinoza’s philosophy: its critical appropriation by an eminent exponent of British Idealism, Harold H. Joachim, and the opposite existentialistic interpretation by Karl Jaspers, who instead sets out a decidedly irrationalistic interpretation of it. Starting with an immanent critique of Jaspers’ failed Spinoza-interpretation, this book ends with the outline of a systematic critique of Existential Ontology
L'etica dell'idealismo moderno
No full textThis book is a systematic work in which its author proposes to set out a complete treatment of the problematic of Moral Philosophy, and identifies in the development of modern thought from Spinoza to the most recent outcomes of Anglo-Saxon Idealism the historical framework in which its deepest and most consistent statements have been formulated. All the philosophical doctrines there expounded are submitted to an immanent theoretical critique from the viewpoint of Absolute Idealism
STORICISMO E METAFISICA NELLA FILOSOFIA CONTEMPORANEA
No full textIn this essay, the author proposes to articulate concisely a theoretically consistent solution to the much-discussed problem of the relationship between the metaphysical and historical dimensions of philosophical thought. He rejects both the anti-historical orientation of the traditional, dualistic “metaphysics of Being” and the prevailingly relativistic outlook of contemporary Historicism, and searches for a reconciliation of both dimensions within the theoretical framework of Absolute Idealism
