Novam in femina virtutem novo genere honoris: le statue femminili a Roma nelle strategie propagandistiche di Augusto
The essay analyses the occurrences in the literary tradition of the mention of women (Caia Cecilia, Caia Taracia, Lucretia, Tarpea, Cloelia, Claudia Quinta and Cornelia) honored by the granting of an effigy in a public place during the Roman Republic: the ancient texts allow to reconstruct a framework in which it is clear an interference in the historical memory due to Augustus and his entourage. This operation aimed to present the privileges granted to Octavia and Livia, sister and wife of the princeps, in 35 BC and in 9 BC as an act done in accordance with the tradition and at the same time to create a comparing relationship between the women of the gens of Augustus and the matrons that before them had obtained the privilege of being honored by a statue. The association of Octavia and Livia with these illustrious ancestors indirectly contributes to strengthen their public position (as for Augustus in his forum) and to allow them to be identified as exempla of feminine virtues by their contemporarie

LA GLITTICA COME ESPRESSIONE D’IDENTITÀ CULTURALE? IL CASO DEI SIGILLI CILINDRICI MESOPOTAMICI ALL’INIZIO DEL III MILLENNIO A.C
The glyptic production at the beginning of the III millennium BC in “Great Mesopotamia” is marked by a passage from an international style to a development of regional and local styles. This process could mirror a redefinition of cultural identities in this territory. The aim of this paper is on one hand to investigate the cultural identities of these ancient people through the study of the iconographies attested in cylinder seals, considered as forms of self-representation; on the other, to recognize the mechanisms of definition of these identities consisting in assimilation or refusal of others’ symbolic elements
Pratiche performative e costruzione dell'identità nella Roma repubblicana: i funerali femminili
‐Methylation of Amines Using Carbon Dioxide and Phenylsilane
A series of six Mn(I) complexes with general formula [MnBr(bisNHC)(CO)(3)], having a bidentate bis(N-heterocyclic carbene) ligand (bisNHC), has been developed by varying the bridging group between the NHC donors, the nitrogen wingtip substituents and the heterocyclic ring. The synthesis of the complexes has been accomplished by in situ transmetalation of the bisNHC from the corresponding silver(I) complexes. Removal of the bromide anion affords the corresponding solvento complexes [Mn(bisNHC)(CO)(3)(CH3CN)](BF4). The influence of the bisNHC structure on its electron donor ability has been evaluated by FTIR and C-13 NMR spectroscopy, both in the neutral and cationic complexes. Finally, the isolated Mn(I)-bisNHC complexes have been employed as homogeneous catalysts in the reductive N-formylation and N-methylation of amines with CO2 as C1 source and phenylsilane as reducing agent, showing a high selectivity for the N-methylated product. Preliminary mechanistic investigations suggest that, in the adopted reaction conditions, the formylated product can be formed via different reaction pathways, either metal-catalyzed or not, while the methylation reaction requires the use of the Mn(I) catalyst
Qualità nutrizionale di Döner Kebab commercializzato in due città del Veneto
Nel periodo compreso fra settembre e ottobre 2012 sono stati campionati 7 esercizi ubicati nella città di Verona e 13 esercizi nella provincia di Vicenza, di cui 11 ubicati in città e 2 a Bassano del Grappa (VI). Lo studio aveva l’obiettivo di effettuare la misura del valore energetico, della composizione bromatologica e del profilo degli acidi grassi di Döner Kebab pronto per il consumo. Al fine di poter stimare con una certa accuratezza la percentuale dei quattro principali ingredienti (pane o piadina, verdura, salse e carne) all’atto del campionamento si è proceduto con il prelievo in contenitori separati dei suddetti ingredienti mantenendo, in ciascun esercizio, le proporzioni abituali di allestimento del piatto. In laboratorio si è proceduto con il rilievo del peso dei singoli ingredienti cui ha fatto seguito la macinazione e omogenizzazione degli stessi. Dall’omogenato sono state prelevate le aliquote per la determinazione analitica di: i) valore energetico mediante bomba calorimetrica, ii) umidità mediante essicazione a 102 °C, iii) proteina grezza mediante metodo Kjeldahl e coefficiente di conversione dell’azoto 6,25, iv) grasso grezzo per via gravimetrica, v) ceneri a mezzo combustione in forno a muffola, vi) sale con il metodo di Volhard modificato, vii) amido mediante metodo enzimatico, viii) collagene (riferito alla carne) mediante idrolisi acida, ossidazione dell’idrossiprolina a pirrolo, sua complessazione con il reattivo di Ehrlich e misura dell’assorbanza dell’addotto a 558 nm, ix) fibra alimentare mediante metodo gravimetrico-enzimatico. Il profilo degli acidi grassi è stato ottenuto in gascromatografia. I risultati hanno evidenziato una elevata standardizzazione della ricetta laddove il confronto fra città ha rilevato nella concentrazione di amido l’unica differenza significativa. L’ingrediente più variabile, in termini percentuali, è risultato essere la carne (min. 22,7% e max. 56,5%). La porzione di vendita aveva un peso medio di 402 g (min 274 g, max 618 g). L’apporto energetico della porzione media del presente campionamento soddisfava il 47% e il 37% dell’assunzione giornaliera raccomandata (RI) di energia per la femmina e il maschio rispettivamente. Nei confronti dei diversi macronutrienti, rispettivamente per la femmina e il maschio adulti, la porzione media copriva il 100% e 86% del RI di proteina, il 31% e 36% degli acidi grassi monoinsaturi, il 51% e 39% dei polinsaturi, il 34% e 28% degli acidi grassi n3, e il 32% e 25% del fabbisogno di acido alfa-linolenico. Inoltre, la porzione media apportava il 71% del RI di sale, il 47% e 31% del RI di acidi grassi saturi e il 15% e 12% del RI di fibra alimentare per la femmina e il maschio adulti rispettivamente. In conclusione, Döner Kebab è un piatto ad elevato contenuto energetico e di macronutrienti, che dal punto di vista nutrizionale può essere considerato un sostituto occasionale di uno dei due pasti giornalieri
D-optimal and highly D-efficient designs with non-negatively correlated observations
summary:In this paper we consider D-optimal and highly D-efficient chemical balance weighing designs. The errors are assumed to be equally non-negatively correlated and to have equal variances. Some necessary and sufficient conditions under which a design is D*-optimal design (regular D-optimal design) are proved. It is also shown that in many cases D*-optimal design does not exist. In many of those cases the designs constructed by Masaro and Wong (2008) and some new designs are shown to be highly D-efficient. Theoretical results are accompanied by numerical search, suggesting D-optimality of designs under consideration
Agronomic performance of 21 new disease resistant winegrape varieties grown in northeast Italy
The goal of the field trial was to evaluate the agronomic per-formance of 21 (10 red and 11 white) winegrape varieties obtained from recent breeding programmes for disease re-sistance developed in Hungary, Germany, and Italy. The test-ed red varieties were as follows: 'Cabernet Carbon', 'Caber-net Eidos', 'Cabernet Volos', 'Julius', 'Merlot Khorus', 'Merlot Kanthus', 'Monarch', 'Prior', UD. 31.103, 'Vinera'. The tested white varieties were as follows: 'Aromera', 'Bronner', 'Fleur -tai', 'Johanniter', 'Muscaris', 'Souvignier Gris', 'Sauvignon Kretos', 'Sauvignon Nepis', 'Sauvignon Rytos', 'Solaris', 'Soreli'. 'Merlot' (red) and 'Glera' (white) were included as control. The experimental vineyard was established in Castelfranco Veneto on the plain, in 2014. Spray treatments were applied against downy and powdery mildew, by using only copper and sulphur. Grape production, grape quality, and phenol-ogy were recorded over a six-year-period, while disease re-sistance (downy mildew, powdery mildew, black rot and an-thracnose) was detected only during a few years. The most significant findings were: a) all varieties showed a good level of downy mildew resistance, especially 'Cabernet Carbon', 'Monarch', 'Prior', UD 31.103, 'Muscaris', 'Solaris', 'Souvignier Gris', 'Bronner', 'Fleurtai', 'Aromera'; b) no powdery mildew attacks were detected in any variety; c) 'Monarch', 'Muscaris', 'Solaris' and 'Souvignier Gris' also showed a high level of re-sistance towards black rot and anthracnose; d) red grape va-rieties had an earlier bud burst as compared to 'Merlot', and, concerning ripening, some varieties were earlier than 'Mer-lot', other ones were later; e) white varieties had a later bud burst but an earlier ripening time as compared to 'Glera'; f) grape production and quality changed significantly depend-ing on the varieties, being titratable acidity higher than 6.4 g L-1 tartaric acid and pH lower than 3.5; also the year affected in a significant way those parameters as well as the interac-tion between the genotype and the year. In conclusion, the tested varieties behaved positively in terms of environmental sustainability
