Detergency in Liquid CO2
No full textIn this dissertation we study Detergency in liquid Carbon Dioxide. Detergency is the cleaning performance of additives, surfactants in particular, in washing fluids. Liquid CO2 is under consideration, for environmental and toxicological reasons, to replace perchloro-ethylene as the solvent in textile dry cleaning technology. Inherent problems of such a transition were confronted with the methodology of chemical engineering design. The Basic Cycle of Design (BCD) approach was used as a pathway for designing a detergent. The BCD also establishes the structural framework of the thesis, which can, therefore, be read as records from a successful product engineering project, in which an effective detergent has been designed for a new dry cleaning solvent. The Dynamic Detergency Model (DDM), which succeeds to explain the role of surfactants in the washing operation, is used as a rational starting point for the design of a detergent in liquid CO2. According to this model, such a surfactant must be: sparingly soluble in the solvent, surface-active and able to form micelles in the solution. The different experiments carried out (solubility, interfacial-tension and dye solubilisation measurements), show that a number of molecules of the homologous polyoxyethylene/alkane series, generally described by the shorthand formula CiEj did indeed behave as surfactants and can be then considered detergents for liquid CO2. In the technical evaluation of the detergents, at laboratory as well as at semi-pilot scale, high washing performances were obtained. They are, indeed, as good for dry cleaning textiles as the present perchloro-ethylene (Perc) technology.Applied Science

The influence of steady blowing and roughness on transitional separated boundary layers
No full textThis paper presents the results of a study between two types of forcing, namely steady blowing and a tripwire, on the control of laminar separated boundary layers. The analysis focuses on the differences in the transition process between these two types of forcing. This effect will be studied using direct numerical simulation. The main differences consists in the coherent structures formed during transition and the overall kinetic energy growth

Skin-Friction Measurements on Mathematically Generated Roughness in a Turbulent Channel Flow
No full textEngineering systems are affected by surface roughness, however, predicting frictional drag has proven to be challenging. The present work takes a systematic approach by generating and manufacturing surfaces roughness where surface statistics, such as rms, skewness and power-spectral density can be controlled. The frictional drag on these surfaces is measured in a turbulent channel flow facility

Novissima Studia : dieci anni di antichistica milanese
No full textThis book collects the written versions of the “Seminari di Dipartimento 2011”. These papers were delivered in the year 2011, namely ten years after the first series of the “Seminari”, by professors and young scholars of the Department of Classics of the Università degli Studi di Milano on topics that have a close relationship with the main research fields of the Department.
Covered areas are archaeology (the interpretation of grave documentation in the Po Valley between rivers Trebbia and Panaro; the results of the excavations carried out in the site of Montebello in the middle of the ager tarquiniensis; the research related to a new archaeological project started in Palmyra in 2007 with the creation of an Italian-Syrian joint mission; and the reconstruction of the history of several ancient sculptures which belonged to private collections), numismatics (ritual uses of coins), ancient history (a new geography of ostracism), classical philology (a new analysis of Simonides’ fr. 34 Poltera, rhetoric in Aristophanes’ comedy, a comparison of Seneca’s attitude towards the cause of noblemen with Sallust’s and Juvenal’s blame against the privileges of nobility), medieval philology (the commentary on Cicero, De inventione, which is commonly attributed to the “magister Menegaldus”, as an hitherto unknown example of Sallust’s success in the Middle Age), oriental studies (the interpretation of the story of Sodom and Gomorrah, the myth of the buffalo-slaying goddess in Hindu tradition).
The author and subject index of all the proceedings of the “Seminari” from 2001 to 2011 closes this book

No full text<p> <i>Trametes neovillosa</i> Fernandes & Gugliotta, <i>nom. nov.</i></p> <p> Basionym: <i>Boletus pavonius</i> Hook., Synopsis Plantarum 1: 10, 1822.</p> <p>MycoBank No.: MB 842811</p> <p> <b>Replaced name</b> — <i>Trametes pavonia</i> (Hook.) Ryvarden. Norw. J. Bot. 19:237, 1972, <i>nom. illeg.</i>, <i>non</i> <i>Trametes pavonia</i> (Berk.) Fr., Nova Acta Regiae Societatis Scientiarum Upsaliensis Ser. 3, 1: 98, 1851.</p> <p> <b>Etymology:</b> — <i>Neo</i> means new in Latin. The name refers to morphological similarity of this species to <i>Trametes villosa</i> (Sw.) Kreisel (1971:83).</p> <p> <b>Notes:</b> — <i>Trametes neovillosa</i> is characterized by the dimidiate to flabelliform basidiomata, upper surface persistently tomentose and concentrically zoned; hymenial surface white to pale ochraceous with circular pores, 5–6 per mm; the basidiospores are hyaline, ellipsoid, 5.1–6.0 × 3.2–4.1 µm.</p> <p> Morphologically, <i>Trametes neovillosa</i> is similar to <i>T. villosa</i> (described from Jamaica), that also has dimidiate to flabelliform basidiomata and upper surface persistently tomentose and concentrically zoned. However, <i>T. villosa</i> has the hymenial surface white to cream, with age becoming brown to pale brown, with angular and often slightly elongated radially pores, 1–3 per mm (larger than <i>Trametes neovillosa</i>), and larger cylindrical basidiospores, 4.8–7.1 × 2.3–3.3 µm.</p> <p> <i>T. pavonia</i> (≡ <i>Daedalea pavonia</i>) has been considered a synonym of <i>Trametes elegans</i> Spreng. (Fr.) (1838:492) (Ryvarden, 1977, Zmitrovich <i>et al.</i> 2012). According to Ryvarden (2016), <i>Trametes elegans</i> and <i>T. neovillosa</i> (as <i>T. pavonia</i>) are widespread and common in tropical America. Morphologically, these species can be easily distinguished, mainly by the arrangement of the hymenophore, which is strictly poroid in <i>T. neovillosa</i> and often lamellate or, sometimes, with sinuous pores to daedaleoid in <i>T. elegans.</i> Furthermore, the distinction of <i>T. neovillosa</i> and <i>T. elegans</i> has been confirmed by phylogenetic data (Justo & Hibbett 2011, Carlson <i>et al.</i> 2014, Olou <i>et al.</i> 2020).</p> <p> Recent studies indicate that <i>Trametes elegans</i> is a polyphyletic group including at least four different species (Justo & Hibbett 2011, Carlson <i>et al.</i> 2014, Olou <i>et al.</i> 2020). According to Carlson <i>et al.</i> (2014), although no clear segregation of morphological characters among these species was observed, geographical distributions are correlated with phylogenetic relationships. They recovered three lineages, named <i>T. elegans</i> I, <i>T. elegans</i> II and <i>T. elegans</i> III. <i>T. elegans</i> II is widely distributed in Central and South America and the Caribbean region with only one isolated from southeastern Asia (Philippines). <i>Trametes elegans</i> originally was described from Guadeloupe (Fries 1821), therefore this clade was considered the true <i>Trametes elegans</i>. <i>T. elegans</i> I occurs exclusively in continental USA, and <i>Trametes aesculi</i> (Fr.) Justo (2014:744) was the name proposed for a member of this complex from continental USA. <i>T. elegans</i> III is predominant in southeastern Asia and Oceania with only one isolated from South America (Venezuela); the name adopted for this clade was <i>Trametes repanda</i> (Pers.) Justo (2014:744), described from Rawak Island (Western Papua, Indonesia). Recently, the name <i>Trametes palisotii</i> (Fr.) Imazeki (1952:57) was re-established for the species previously known as <i>T. elegans</i> in tropical Africa (Olou <i>et al.</i> 2020).</p> <p> Therefore, these data suggest that <i>Daedalea pavonia</i>, described from Sri Lanka, probably doesn’t even belong to <i>Trametes elegans sensu stricto</i>, and further studies may clarify if <i>Daedalea pavonia</i> could represent another species in the genus or be a synonym of <i>T. repanda</i>.</p> <p> The examined specimens of <i>T. elegans</i> from South America are characterized by basidiomata annual, sessile, with a short base in the substrate insertion point, dimidiate to flabelliform; the upper surface is glabrous and the hymenial surface is lamellate or sometimes with daedaleoid pores. The basidiospores are cylindrical, hyaline, smooth and thin-walled, with dimensions ranging from 5.5–7.0 × 3.1–3.5 µm.</p> <p> Although illegitimate, <i>Trametes pavonia</i> has been frequently used in taxonomic works and in the diversity checklist for Tropical America (Baltazar & Gibertoni 2009, Gomes-Silva <i>et al.</i> 2010, Lombana-Alvarez <i>et al.</i> 2016, Ryvarden 2016, Leonardo-Silva <i>et al.</i> 2020).
