I patrimoni e i finanziamenti destinati nelle S.p.A
No full textQuando la legge assegna a un patrimonio una disciplina giuridica particolare e ammette una deroga al principio generale della responsabilità ad esso legata, si parla di segregazione patrimoniale.
I patrimonio destinati in via esclusiva a uno specifico affare ne costituiscono un tipico esempio.
Si tratta, per il nostro diritto, di una novità, tra le più significative, introdotta con la riforma societaria, che garantisce l'inattaccabilità del patrimonio dedicato da parte dei creditori sociali e che limita ad esso la possibilità di rivalsa per i crediti derivanti dal singolo affare.
Gli autori analizzano le problematiche connesse all'applicazione della disciplina dei patrimoni destinati con un testo che si candida ad essere un utile riferimento per affrontare e risolvere le questioni (soprattutto attinenti alle situazioni di crisi d'impresa) che scaturiranno dall'attuazione di questa inedita materia.

Flexible pipe behaviour investigation using two models of internal slug flow regime
No full textIn this work the behavior of a flexible pipe with an inner slug flow regime is presented. The main goal of this study is the comparison of the internal stresses of this type of pipe arising from two different simple models of the slug flow regime. Flexible marine risers in recent years may be considered as an important part of offshore production facilities in order to extract crude oil from natural reservoirs placed at deep sea depth. Their installation has been proved to be fully technically acceptable, also from an economic point of view and often they prove to be the unique solution to the task they are demanded. Along their length, a gaseous phase is often pumped in order to facilitate the suction of the oil. The slug flow is the most frequent multiphase regime involved during the operations. Thus, in this work the authors present two simple models in order to describe exertions which this type of regime puts upon the riser inner wall. In both cases, an equivalent monophase fluid having a travelling sinusoidal density was considered. However, in the second case, a space and time varied slug phase along the entire length of the pipe was implemented. External forces due to the wave motion in terms of Morison's equations, structural damping, bending moment, axial tension, structural damping and bed action (Pollio, 2006; Pollio et al., 2006; Marano et al., 2006) are also modelled. Some results from a numerical model in the time domain of the system, based on the lumped mass approach (Ghadimi, 1988), allowed the authors to make some considerations about the importance of a better description of the slug flow effects into a flexible marine riser characterized by a continuously varied inclination
Investigating the linkages between industrial policies and M&A dynamics: Evidence from China
No full textMergers and acquisitions (M&As hereafter) have been widely examined in the economic and business literature under many perspectives. However, the industry-level view, specifically the relation between industrial policies and M&A waves at the sectoral level, has remained rather unexplored. This article contributes to fill this gap by empirically investigating the relation between selective industrial policies and M&A waves at the industry level in China. Referring to the four Five Year Plans covering the period 1996–2015, we explore whether being identified as an emerging sector in these plans generates positive or negative changes in the number of M&As. We reiterate the analysis according to the different types of M&As (vertical, horizontal or conglomerate) and the different natures of the acquirer (SOEs or private). Our results suggest that policies can differentially affect M&A waves according to the type of M&A. Moreover, while private firms are more responsive to both horizontal and vertical integration in emerging sectors, SOEs are more prone to engage in vertical M&As. We discuss the possible rationales behind the different behaviors. We also draw general policy implications on strategic industrial policy and market restructuring

Dihydrophenanthrene and phenanthrene mimics of natural compounds - synthesis and antialgal activity
No full text9,10-Dihydrophenanthrenes and phenanthrenes, mimics of natural compounds with strong antialgal activity, have been synthesized through cross-coupling of 1-(2-iodo-5-methoxy)-phenylethanol with variously substituted iodobenzenes. The synthetic compounds, bearing a hydroxyl or a methoxyl group at C-2 and a methyl in the C ring, were tested against the green alga Selenastrum capricornutum. All compounds, except 2-methoxy-7- methylphenanthrene, caused inhibition of algal growth by more than 70% at 10-4 M, and many of them retained this strong activity at 10-5 M
Biomass and phycobiliprotein production of Galdieria sulphuraria, immobilized on a twin-layer porous substrate photobioreactor
No full textThe extremophile red alga Galdieria sulphuraria was successfully grown immobilized in a twin-layer porous substrate bioreactor (TL-PSBR). A maximal biomass growth rate of 10 g dry weight m−2 day−1 was measured at a photon fluence rate of 200 μmol photons m−2 s−1 with addition of 1% CO2 and a temperature of 34 °C. Under these conditions, a maximal biomass value of 232 g m−2 was attained after 33 days of growth. Phycobilin productivity, however, was highest at a lower photon fluence rate of 100 μmol photons m−2 s−1 and reached a phycobilin value of 14 g m−2, a phycobilin content in the biomass of 63 mg g−1 and a phycobilin growth rate of 0.28 g m−2 day−1 for phycocyanin and 0.23 g m−2 day−1 for allophycocyanin. Addition of CO2 was essential to enhance growth and phycobilin production in G. sulphuraria and further optimization of the cultivation process in the TL-PSBR appears possible using a multi-phase approach, higher growth temperatures and optimization of nutrient supply. It is concluded that autotrophic cultivation of G. sulphuraria in a TL-PSBR is an attractive alternative to suspension cultivation for phycobilin production and applications in bioremediation

No full textUndular jump formations in very large channels
No full textIn this paper, undular hydraulic jumps in very large channel (channel width equal to 4.0 m) for low Rey-nolds number have been investigated. Jumps with very high aspect ratios are very rare in literature, and, therefore, experimental works are necessary. The main aims are (i) analyzing the lateral shock wave in order to verify the experimental validity of the shock wave theory in very large channel, (ii) analyzing the flow conditions of undular jumps in very large channels. The main results are the following: (i) the pres-ence of well developed lateral shock wave similar to those of oblique jumps were observed; (ii) the com-parison of the experimental results and the theoretical ones show that the classical shock wave theory is confirmed, taking into account the experimental errors; (iii) the literature law of the wave height of first wave crest was confirmed also in the case of very large channel
