Reply to “A critical analysis of Vacca, A., Aru, F., and Ollesch, G. (2017). Short‐term impact of coppice management on soil in a Quercus ilex L. stand of Sardinia. Land Degradation & Development, 28(2), 553–565.” by Giadrossich and Guastini
No full textIn their critical review of Vacca, Aru, and Ollesch (2017), Giadrossich and Guastini noted substantial deficiencies in the research design and methodology, analysis and interpretation of data, and conclusions in the paper that are not supported by the findings. In this reply, we (a) reiterated the aim of our study, (b) provided the evidence that similar research designs are not rare in soil studies, (c) provided the evidence that Giadrossich and Guastini misused our data in their analysis and interpretation, and (d) highlighted that Giadrossich and Guastini used inappropriate citations. Consequently, our findings and conclusions that coppicing has negative short‐term impacts on the soil and that the short‐term soil erosion risk must be considered very high in coppicing management are unaffected by the comments from Giadrossich and Guastini

Multistate Markov Models and Structural Properties of the Transition-Rate Matrix
No full textThis paper explains how to use Markov models for evaluating the availability and reliability of a system when the transition rates of each component depend on the state of the system. To this purpose, the structural properties of the system transition-rate matrix, obtained by the Kronecker sum of transition rate matrices of the components, are analyzed. As a result, an efficient use of the Markov model is possible by mapping the transition rates of the single components into the elements of the system transition-rate matrix. The potential of parallel computers can facilitate this approach, giving renewed interest to the Markov method for complex systems
La memoria della guerra di una comunità
No full textIl volume raccoglie 61 testimonianze inedite degli abitanti di Monserrato che vissero in prima persona i dramnmi del conflitto. In particolare 34 storie riguardano ex combattenti monserratini partiti nei vari fronti di guerra (Russia, Grecia, Francia, Albania, Libia e Etiopia) mentre 27 sono le storie di chi era presente durante lo spezzonamento di Monserrato ad opera degli americani il 31 marzo 1943. L’opera è ricca di immagini e documenti dell’epoca

Voltammetric study on the behaviour of refractory metals in ([BMP][TFSA]) ionic liquid
No full textElectrochemical studies of tantalum fluoride and zirconium fluoride in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide ([BMP][TFSA]) ionic liquid were carried out in presence of lithium fluoride using cyclic voltammetry technique. The electrochemical behaviour of Ta(V) and Zr(IV) on gold and platinum substrates was investigated in the temperature range from R.T. to 200°C at different values of scan rate and different potential windows. Special attention was paid to the mechanism of cathodic reduction. Cyclic voltammetries exhibit well-defined peaks attributed to the formation of metallic deposits on the substrates. The knowledge of electrode and chemical reactions based on the experimental results of the refractory metals considered allow us to propose a possible reaction path for the oxidation/reduction processes. The mechanisms of electrochemical reduction of Tantalum(V) depends strongly on the composition of the bath; using TaF5 as metal salt, two cathodic peaks due to Ta(V)/Ta(III) and Ta(III)/Ta reduction were observed. The cyclic voltammograms recorded at different values of scan rate have shown that the Ta(III)/Ta reduction process is mainly controlled by diffusion of the electroactive species to the electrode surface. It has been proposed that the mechanism for reduction of zirconium ions occurs in a one step process exchanging four electrons and controlled by the zirconium ions diffusion in the ionic liquid
The New Middle Ages: Medievalism in McLuhan and Vacca
No full textA very successful book formulated years ago in its title, The Coming Dark Age, (from the original Italian, Il medioevo prossimo venturo, by Roberto Vacca, published in 1971) a sense of anxiety over planetary end-of-the-second-millennium problems, such as "nuclear holocaust, overpopulation, pollution and ecological disaster". What is interesting in these short-range prophecies is that one may live long enough to recognize their fallacy. Vacca predicted that we would be right in the new Middle Ages by the end of the millennium. Marshall McLuhan also spoke of the reappearance of the Middle Ages, but in totally different terms, indicating how medieval our contemporary world really is, because of the shift from a visually biased to a multisensorial perception, imposed on us by the passage from the mechanically oriented culture of the past to the one, based on electronics, in which we live
On the Non-Linear Problem of Fluid Distribution Networks in Quasi-Steady Condition of Flow
No full textThe direct nonlinear problem of a fluid distribution network in unsteady state of flow is dealt within this paper Referring to a class of nonlinear flow equations several issues related to the mathematical well-posedness are analyzed. A mixed variational formulation in terms of the state variables of the network along with a weak formulation with respect to the time variable is associated to the classical differential algebraic problem formulation. The strict convexity of network functional and the uniform monotonicity of the operator resulting from the temporal discretization allow the proof of the uniqueness of the solution and provide a necessary condition for global stability
