Il Codex DCCCIX (DCCCXIII) della Biblioteca Capitolare di Verona: «prima trascrizione delle Istituzioni di Gaio» o «copia del tutto inservibile»?
2016
Partendo da una considerazione critica della tesi avanzata da Briguglio nel libro intitolato "La prima trascrizione delle Istituzioni di Gaio. Il Codex DCCCIX (DCCCXIII) Gaii Institutionum Libri della Biblioteca Capitolare di Verona" (2013), si contesta l'idea che la trascrizione parziale delle Istituzioni di Gaio ancor oggi custodita nella Biblioteca Capitolare di Verona (Codex DCCCIX) sia la prima versione in bella copia dei lavori di trascrizione del palinsesto gaiano (Verona, Biblioteca Capitolare, Codex XVI. Un esame più completo del Codex DCCCIX confrontato con le trascrizioni complete conservate nella Staatsbibliothek zu Berlin (Ms. lat. Fol. 308), infatti, dimostra che tale tesi non…
Le prime trascrizioni del palinsesto di Gaio e il presunto «mistero» delle schede veronesi (BCapVr, Cod. DCCCIX)
2014
This paper addresses the question of the origin of the partial transcription of Gaius’ palimpsest still preserved in the Capitular Library of Verona (BCapVr, Cod. DCCCIX) and allows to solve the pretended «mystery» about its presence in this library. A comparison with the fair copy (Reinschrift) of the transcription belonging to the Berlin State Library – Prussian Cultural Heritage (SBB-PK, Ms. lat. fol. 308, K. 1, Konv. 1) shows that the Cod. DCCCIX of the Capitular Library can not be regarded as a forgotten copy or a gift. Similarly, the idea that the manuscript was the first fair copy of the transcription works is not plausible. Anyway, a neglected information provided by one of the Prus…
Green small technology for neighbourhood regeneration: a southern case-study.
2012
I rifiuti possono trasformarsi da problema ad opportunità se si transita da un’amministrazione del consumo e dello spreco ad una gestione che si proponga l’ottimizzazione nell’uso delle risorse e la valorizzazione degli scarti. Il trattamento della frazione organica dei rifiuti per la produzione di biogas, calore di processo e compost di qualità può rappresentarne un aspetto di forte rilievo. La scala di quartiere, indicata nel lavoro di ricerca che viene presentato, può consentire, per certi versi, la scomposizione della complessa realtà metropolitana e la declinazione efficiente del paradigma del principio di prossimità, dell’autosostentamento e del coinvolgimento delle comunità locali pe…
Dwa typy reformacyjnych liturgii Wieczerzy Pańskiej
2021
W artykule najpierw zostały krótko ukazane wybrane tendencje i fenomeny, spotykane w pobożności późnego średniowiecza, które pośrednio lub bezpośrednio wpłynęły na kształtowanie się życia liturgicznego reformacji. Następnie w głównej części przedłożenia omówiono dwa zasadnicze typy liturgii Wieczerzy Pańskiej, które ukonstytuowały się w pierwszych latach reformacji: tzw. typ mszalny oraz tzw. typ górnoniemiecki. Przedstawiono genezę, proces kształtowania się i strukturę najważniejszych prototypów liturgii Wieczerzy bez szczegółowego analizowania licznych obrządków na nich wzorowanych. W końcowej części artykułu reformacyjne liturgie Wieczerzy Pańskiej zostały w ogólny sposób scharakteryzowa…
Polyphenoloxidase from Riesling and Dornfelder wine grapes (Vitis vinifera) is a tyrosinase.
2015
Abstract Polyphenoloxidases (PPO) of the type-3 copper protein family are considered to be catecholoxidases catalyzing the oxidation of o-diphenols to their corresponding quinones. PPO from Grenache grapes has recently been reported to display only diphenolase activity. In contrast, we have characterized PPOs from Dornfelder and Riesling grapes which display both monophenolase and diphenolase activity. Ultracentrifugation and size exclusion chromatography indicated that both PPOs occur as monomers with Mr of about 38 kDa. Non-reducing SDS–PAGE shows two bands of about 38 kDa exhibiting strong activity. Remarkably, three bands up to 60 kDa displayed only very weak PPO activity, supporting th…
High precision mass measurements for wine metabolomics
2014
An overview of the critical steps for the non-targeted Ultra-High Performance Liquid Chromatography coupled with Quadrupole Time-of-Flight Mass Spectrometry (UPLC-Q-ToF-MS) analysis of wine chemistry is given, ranging from the study design, data preprocessing and statistical analyses, to markers identification. UPLC-Q-ToF-MS data was enhanced by the alignment of exact mass data from FTICR-MS, and marker peaks were identified using UPLC-Q-ToF-MS(2). In combination with multivariate statistical tools and the annotation of peaks with metabolites from relevant databases, this analytical process provides a fine description of the chemical complexity of wines, as exemplified in the case of red (P…
Characterization of prehispanic cosmetics found in a burial of the ancient city of Teotihuacan (Mexico)
2012
The present paper reports the chemical data obtained on samples of pigmenting materials contained in 31 miniature vessels found in a burial found in Teopancazco, a multiethnic neighborhood center located in the southeastern sector of the archaeological site of Teotihuacan (Central Mexico) and the analytical protocol established for the complete characterization of these archaeological materials. For this purpose a multi-technique approach based on the combination of several non destructive and micro-destructive instrumental techniques, namely, light microscopy (LM), scanning electron microscopy-X-ray micro-analysis (SEMe EDX), transmission electron microscopy (TEM), voltammetry of micropart…
Harvesting canthinones: identification of the optimal seasonal point of harvest of Zanthoxylum chiloperone leaves as a source of 5-methoxycanthin-6-o…
2015
This article is focused on the seasonal variation in the contents of 5-methoxycanthin-6-one from the leaves of Zanthoxylum chiloperone (Rutaceae). Based on the pharmacological interest presented by 5-methoxycanthin-6-one, its seasonal variation in Z. chiloperone leaves was analysed in order to determine the best time for harvesting, optimising the 5-methoxycanthin-6-one content. The seasonal dynamics of canthinone alkaloids can be the key to improve the isolation from natural sustainable sources, such as leaves. Complementarily, this study describes the phytochemistry of leaf from this Ruraceae species.
Synchronization and fluctuations for interacting stochastic systems with individual and collective reinforcement
2020
The Pólya urn is the paradigmatic example of a reinforced stochastic process. It leads to a random (non degenerated) time-limit. The Friedman urn is a natural generalization whose a.s. time-limit is not random anymore. In this work, in the stream of previous recent works, we introduce a new family of (finite) systems of reinforced stochastic processes, interacting through an additional collective reinforcement of mean field type. The two reinforcement rules strengths (one componentwise, one collective) are tuned through (possibly) different rates n −γ. In the case the reinforcement rates are like n −1 , these reinforcements are of Pólya or Friedman type as in urn contexts and may thus lead …
Production of photon states from Λ-atoms in a cavity
2019
We analyse the system of Λ-atoms in a cavity QED of semi-transparent mirror and driven by laser fields. We derive effective models and connect concepts (photonic flux, input-output operators, photonic state) characterizing the propagation of the resulting leaking photons. We propose an atom-cavity non-resonant scheme for single-and 2-photons generation. The pulse shapes of outgoing single photons are tailored using a specifically designed driving field envelope. For the production of 2-photon states, two trapped atoms are used with two driving pulses. Their pulse shapes are characterized and it is shown that the multiphoton outgoing photonic states cannot be Fock states, since the photons a…
