Vesuviana
No full textIl programma Vesuviana, attivo dal 1997, ha l'obiettivo di mettere a sistema il contributo dell'Ateneo di Bologna alla migliore conoscenza e valorizzazione dei siti vesuviani, in collaboarzione e in convenzione con gli enti per la tutela. Dal 1997 ad oggi ha attivato più progetti di ricerca e didattica, a Pompei (dal 1998) e ad Ercolano (dal 2005), con il Museo Archeologico Nazionale di Napoli (dal 2006) e infine a Villa Sora (dal 2016). Forte di una ricca bibliografia (fra cui Vesuviana. Archeologie a confronto, 2009, e DHER. Domus Herculanensis Rationes. Sito archivio museo, 2011, entrambi a cura di Antonella Coralini), sta per dare alla luce nuove monografie
Anion Recognition in Water with Use of a Neutral Uranyl-salophen Receptor
No full textA new water-soluble uranyl-salophen complex incorporating two glucose units has been synthesized. This neutral derivative shows noteworthy binding affinity for fluoride in water thanks to the Lewis acid base interaction occurring between the metal and the anion. Such interaction is strong enough to overcome the high hydration enthalpy of fluoride. Moreover this complex effectively binds hydrogen phosphate and exhibits remarkably strong association for nucleotide polyanions ADP(3-) and ATP(4-)
Iniziative di divulgazione delle tematiche della conservazione attraverso la collezione delle piante della flora vascolare pugliese di importanza conservazionistica.
No full textLa tutela della biodiversità vegetale, in particolare della Flora pugliese, occupa un ruolo primario nelle
attività del Museo Orto Botanico dell’Università di Bari “Aldo Moro” con la realizzazione di una serie di
progetti di conservazione in situ ed ex situ. Nel corso degli anni è stata costituita presso l’Orto Botanico una
Collezione di piante della Flora vascolare pugliese di importanza conservazionistica. Questa è attualmente
composta da circa 50 taxa di particolare interesse in quanto rari, minacciati di estinzione sul territorio
regionale od anche nazionale, endemici o comunque di importanza fitogeografica. Gli individui della
collezione derivano da propagazione gamica a partire da germoplasma collezionato in campo e conservato
presso la Banca del Germoplasma del Museo Orto Botanico dell’Università di Bari (BG-MOBB), ossia
senza prelievo di piante in natura. Molti di questi taxa sono legati a progetti di conservazione in situ, per i
quali, quindi, sono stati messi a punto gli specifici protocolli di propagazione. Questa collezione, anche se
non è propriamente una collezione ex situ in vivo finalizzata alla conservazione, si caratterizza sempre più
come un efficace strumento per la divulgazione delle tematiche conservazionistiche, considerando anche il
suo stretto legame con i diversi progetti di conservazione e le modalità con cui è stata costituita. I visitatori del Museo vengono informati sull’importanza e sulle modalità di svolgimento dei progetti di conservazione mediante esempi concreti che risultano molto efficaci dal punto di vista didattico-divulgativo
Online resources for mathematics in the scientific virtual reference desk
No full textThe present work briefly describes the Virtual Reference Desk for mathematics elaborated during the time I worked at the CERN Library (European Laboratory for Particle Physics or Laboratoire européen pour la physique des particules) in Geneva. This instrument is dedicated to the CERN librarians, with whom I have shared important moments of my professional career. In particular, I would like to gratefully acknowledge their valuable co-operation and assistance during our time spent working together. The Web metasource is comprised of three directories, annotated and interrelated with dual application: The first is intended as a work tool for librarians working in mathematics libraries, but above all for librarians of high energy physics, who more often than not must turn to mathematics and the use of mathematical applications and models for the physical sciences and in particular particle physics. The second is an on-line resource for mathematics; that is, a Virtual Reference Desk for the community of mathematicians, with whom I have been collaborating for some twenty years at the University of Padova. The bibliographical instrument is born from the need to have at our disposal a scientific Virtual Reference Desk created according to the needs of those working in physics and mathematics libraries – a tool which is comprised of materials collected during years of work as much as material available on-line through the use of new technologies
Cl-IB-MECA enhances TNF-α release in peritoneal macrophages stimulated with LPS.
No full textAdenosine receptor A3 (A3R) belongs to the Gi/Gq-coupled receptor family, that leads to the intracellular cAMP reduction and intracellular calcium increase, respectively. A3R is widely expressed and it can play a crucial role in many patho-physiological conditions, including inflammation. Here we investigate the effect of Cl-IB-MECA, A3R agonist, on the production of TNF-α. We found that Cl-IB-MECA enhances LPS-induced TNF-α release in peritoneal macrophages. This effect is reduced by MRS1191, A3R antagonist and by forskolin, activator of adenylyl cyclase. pIκBα increased in LPS+Cl-IB-MECA-treated macrophages, while total IκB kinase-β (IKKβ) reduced. Indeed, p65NF-κB nuclear translocation increased in cells treated with LPS+Cl-IB-MECA. Moreover, IMD 0354, IKKβ inhibitor, significantly abrogated the effect of Cl-IB-MECA on TNF-α release. Inhibition of protein kinase C (PKC) significantly reduced Cl-IB-MECA-induced TNF-α release in LPS-stimulated macrophages. Furthermore, LY-294002, PI3K inhibitor, reduced the TNF-α production enhanced by Cl-IB-MECA, although the phosphorylation status of Akt did not change in cells treated with LPS+Cl-IB-MECA than LPS alone. In summary, these data show that Cl-IB-MECA is able to enhance TNF-α production in LPS-treated macrophages in an NF-κB- dependent manner
Intervista con Antonella De Robbio, Responsabile del Settore Progetti e Biblioteca Digitale del Centro d'Ateneo per le Biblioteche CAB dell' Università di Padova e Referente per il diritto d'autore del Sistema Bibliotecario di Ateneo
No full textThe interview with Antonella De Robbio – manager of the “Project Sector and Digital Library” for CAB (Centro di Ateneo per le Biblioteche) of the University of Padua and copyright expert for Sistema Bibliotecario di Ateneo – was published in Pinali news.
Antonella De Robbio answered the following questions:
1) How to deal with the issues of author’s intellectual and economic rights in the context of scientific publishing and digital library?
2) What is the influence of the digital approach on the traditional ways to create and disseminate scientific communication?
3) In your opinion, can the experiences of University Press and the Open Archives represent the path to follow in order to overcome the paradox that a scientific author is also the user of his publisher?
4) Which are the outcomes of the fight between copyright and copyleft?
5) Which of these approaches are more suitable to label the metaphor of the “Society of Knowledge”
Literacy in Neapolitan Women's Convents in the Middle Ages and the Contribution of Digital Archives on Monasterium.Net
No full textAntonella Ambrosio seeks a viable way of carrying out research on this topic: the palaeographic analysis of the few available sources using a multidisciplinary approach that combines diplomatics, archival, and historical research. This approach ensures the appropriate contextualization of the source both historically and culturally. In "Literacy in Neapolitan Women's Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger", Ambrosio provides a case study, analysing a single piece of handwriting evidence. The source is an accounts ledger from the Dominican convent of Santi Pietro e Sebastiano compiled in the second half of the fifteenth century, from 1485 to 1496. Using an analytical approach, the author has identified the handwriting of a particular (anonymous) nun from the convent; Ambrosio studies the script the nun used and formulates hypotheses about her cultural background and how she learned to write. The palaeographic analysis is fully contextualized thanks to the reconstruction of the old convent archive, a reconstruction helped by using digital technologies now accessible online at Monasterium.net. As Ambrosio's work demonstrates, technological advances may aid codicological work but careful palaeographic analysis is necessary to ascertain the participation of female scribes. In this case we witness the scribal development of a nun who began with a basic knowledge of writing and who went on to perform her practical task not well but adequately for the purpose

Literacy in Neapolitan Women’s Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger
No full textThis paper is about a research i on the literacy and writing skills of Neapolitan sisters in medieval convents, due to the lack of adequate historical study of such nuns and the extremely complex nature of the documentary sources. Surviving evidence is scattered far and wide, and the old convent archives have been dispersed. Given the state of the survivals, Antonella Ambrosio seeks a viable way of carrying out research on this topic: the palaeographic analysis of the few available sources using a multidisciplinary approach that combines diplomatics, archival, and historical research. This approach ensures the appropriate contextualization of the source both historically and culturally. In ‘Literacy in Neapolitan Women’s Convents: An Example of Female Handwriting in a Late Fifteenth-Century Accounts Ledger’, Ambrosio provides a case study, analysing a single piece of handwriting evidence.
