L'Écriture à rebours. Le Roman de Méliadus du XIIIe au XVIIIe siècle

Continuation elleptique du "Tristan en prose", qui s'inscrit dans l'interstice séparant la naissance de Tristan du remariage de Méliadus avec la fille du roi Hoël, le "Roman de Meliadus" (1235-1240) est une oeuvre demeurée ouverte, de par son inachèvement et de par le dialogue constant qu'il instaure avec les autres romans arthuriens. S'il revendique sa filiation et assume son statut de récit puîné, les réminiscences qu'il exhibe masquent aussi les gauchissements, les infléchissements qui lui permettent de faire du neuf avec du vieux. C'est ce jeu - aux deux sens du terme - que Barbara Wahlen étudie et montre à voir, non seulement dans le "Roman de Meliadus" proprement dit, mais également dans trois de ses relectures, qui actualisent et renouvellent la signification du roman en profondeur. La première est une continuation de la toute fin du XIIIe ou du début du XIVe siècle qui est aujourd'hui conservée par le seul manuscrit Ferrell 5. La deuxième actualisation retenue est celle qu'offre "Meliadus de Leonnoys", l'imprimé publié en 1528 par Galliot du Pré, fruit d'un minutieux travail de découpage et de remontage. La dernière enfin est l'extrait paru en 1776 dans la "Bibliothèque Universelle des Romans".

Sulfur isotope analysis of cinnabar from Roman wall paintings by elemental analysis/isotope ratio mass spectrometry - tracking the origin of archaeological red pigments and their authenticity

The most valuable pigment of the Roman wall paintings was the red color obtained from powdered cinnabar (Minium Cinnabaris pigment), the red mercury sulfide (HgS), which was brought from mercury (Hg) deposits in the Roman Empire. To address the question of whether sulfur isotope signatures can serve as a rapid method to establish the provenance of the red pigment in Roman frescoes, we have measured the sulfur isotope composition (delta(34) S value in parts per thousand VCDT) in samples of wall painting from the Roman city Aventicum (Avenches, Vaud, Switzerland) and compared them with values from cinnabar from European mercury deposits (Almaden in Spain, Idria in Slovenia, Monte Amiata in Italy, Moschellandsberg in Germany, and Genepy in France). Our study shows that the delta(34) S values of cinnabar from the studied Roman wall paintings fall within or near to the composition of Almaden cinnabar; thus, the provenance of the raw material may be deduced. This approach may provide information on provenance and authenticity in archaeological, restoration and forensic studies of Roman and Greek frescoes. Copyright (c) 2010 John Wiley & Sons, Ltd.

'Greek' and 'Roman' in Latin Medical Texts. Studies in Cultural Change and Exchange in Ancient Medicine : [Proceedings of the 10th International Conference "Ancient Latin Medical Texts", Lausanne, 2010, November 3rd-6th November]

Latin medical texts transmit medical theories and practices that originated mainly in Greece. This interaction took place through juxtaposition, assimilation and transformation of ideas. 'Greek' and 'Roman' in Latin Medical Texts studies the ways in which this cultural interaction influenced the development of the medical profession and the growth of knowledge of human and animal bodies, and especially how it provided the foundations for innovations in the areas of anatomy, pathology and pharmacology, from the earliest Latin medical texts until well into the medieval world.

Adsorció de crom (VI) i crom (III) en solució amb closca de cranc

En l’eliminació del crom en suspensió de les aigües residuals de les indústries es realitzen dos processos: una precipitació en medi àcid on es redueix el crom (VI) a crom (III) en què s’elimina la major part del crom, i el següent tractament es fa per bescanvi iònic o per adsorció. Els adsorbents emprats actualment tenen un elevat cost i s’està estudiant nous adsorbents, com a substituts dels tradicionals, de baix cost. Dins d’aquest adsorbents de baix cost es troben els bioadsorbents, biomaterials amb gran capacitat d’adsorció. L’objectiu del projecte es va centrar en l’estudi de l’adsorció de crom trivalent i hexavalent en solucions aquoses utilitzant com a adsorbent el residu industrial de closca de cranc, provinent d’una indústria alimentària de barretes de cranc

First detection of Rio Negro virus (Venezuelan equine encephalitis complex subtype VI) in Córdoba, Argentina

Rio Negro virus (RNV) (Venezuelan equine encephalitis subtype VI) circulates only in Argentina; in northern provinces, isolates have been obtained from mosquitoes and rodents since 1980 and have been associated with acute febrile illness in humans. However, no studies of RNV have been performed in the central area of the country. We carried out molecular and serological detection of RNV in Córdoba, a province of the central part of the country, in mosquitoes and humans, respectively. One mosquito pool tested positive for alphavirus RNA by reverse transcriptase-nested polymerase chain reaction (RT-nested PCR). Subsequent sequencing determined that this alphavirus grouped with RNV. Serological studies detected antibodies to RNV in one human serum sample, which was obtained during the same period that RNV was detected using the aforementioned molecular methods. This is the first report of RNV circulation in the central area of Argentina, indicating an expansion of its original distribution. These results highlight the importance of strengthening surveillance procedures in endemic areas, as well as in new regions where RNV may emerge.
