Note sui carmi 210 - 214 R (= 201 - 205 Sh. B.) dell’'Anthologia latina'
No full textWithin the Latin Anthology, the section 210-214 R (= 201-205 Sh.B.), which was composed by Felix vir clarissimus, celebrates the thermal baths built by the king Thrasamundus (496-523) in a place near Carthage called Alianas. This paper focuses to the quality of the handwritten tradition, against the secular accumulation of conjectures: only the text of the Codex Salmasianus (Parisinus Latinus 10318) itself is able to clarify the context and the true meaning of these poems

Enhancement of archaeological sites and human remains in decentralized areas: territorial expansion and ethical education through the involvement of students
No full textThe enhancement of archaeological sites with human remains is an essential practice to preserve and understand our past, but these realities also constitute a unique opportunity to involve both the community and especially the students in stimulating and interdisciplinary lessons.
The "Archaeological Itinerary of the Valcuvia territory", with its focus on the recovery of human remains from peripheral archaeological sites, is a virtuous example of the use of innovative teaching strategies, activating information and training courses on the various historical, archaeological, anthropological and ethical problems, through the history of ancient populations
Simulation of coalescence, break up and mass transfer in bubble columns by using the Conditional Quadrature Method of Moments in OpenFOAM
No full textThe evaluation of the mass transfer rates and the fluid-dynamics aspects of bubble columns are strongly affected by the intrinsic poly-dispersity of the gas phase, namely the different dispersed bubbles are usually distributed over a certain range of size and chemical composition values. In our previous work, gas-liquid systems were investigated by coupling Computational Fluid Dynamics with mono-variate population balance models (PBM) solved by using the quadrature method of moments (QMOM). Since mass transfer rates depend not only on bubble size, but also on bubble composition, the problem was subsequently extended to the solution of multi-variate PBM (Buffo et al. 2013). In this work, the conditional quadrature method of moments (CQMOM) is implemented in the open-source code OpenFOAM for describing bubble coalescence, breakage and mass transfer of a realistic partially aerated rectangular bubble column, experimentally investigated by Diaz et al.(2008). Eventually, the obtained results are here compared with the experimental data availabl

Although <i>D. burkartii</i> was treated as <i>D. riedelii</i> for more than 70 years (Burkart 1939, Vanni 2001), these species are not particularly alike except for the terminal pseudoracemose inflorescence, as can be seen in the comparison presented in the Table 1. Among the species of <i>Desmodium</i> in Argentina, <i>D. burkartii</i> is most similar to <i>D. glabrum</i> (Mill.) Hitchc. They share the same large loment with ca. 7 <i>–</i> 9 mm wide, but <i>D. burkartii</i> differs by presenting leaflets elliptic-lanceolate (× rhomboid in <i>D. glabrum</i>), flowers ca. 10 mm long (× ca. 3mm long), loments with 2 <i>–</i> 6 oblong-articles (× 2 <i>–</i> 4 reniform or rhomboid articles).</p>Published as part of <i>Lima, Laura C.
