Vegetal waste and some wastewater of agro-food industries contain plant secondary metabolites (PSMs). It was showed in nutritional researches that these substances such as saponins and tannins reduced the methane production in the rumen. To our knowledge no study was done in the waste treatment domain to evaluate the inhibitory effect of the principal glycosidic metabolites from the wastewater or vegetal waste on their own methane-producing anaerobic digestion. Therefore in this paper BMP tests were carried out at 30°C with four commercial PSMs (CPSMs) in mixture with glucose monohydrate (Gl) used as control sample. These CPSMs were saponin from Quilaja Saponaria Molina Pract (Sap), tannic acid (Tan), salicin (Sal) and aloin from Curacao Aloe (Alo) representing respectively saponins, tannins, alcoholic glycosides and anthraquinones sources. Acidogenesis and acetogenesis were recorded for all the mixtures of Gl and CPSMs; however their conversion rates decreased with the increase of the concentrations of CPSMs. By contrast, the methanogenesis was inhibited at concentrations of CPSMs above 0.3 g/l. The inhibition degree for aromatic compounds on the anaerobic biodegradation of Gl seemed directly to depend on the numbers of benzene rings in the medium and the synergism. Thus, the highest inhibition of the biogas production from Gl was recorded for Alo, followed by Sap, Tan and Sal. However, the highest inhibition of the methane production from Gl was recorded with Sap, Alo, Tan and Sal. It was supposed that the toxicity potentials of these PSMs on the own biomethanization would be in following decreasing order: Sap or Alo, Tan and Sal. Therefore, the concentration of PSMs alone or in mixture in a digester should be bellow 0.3 g/l. for a better methanization . [less ▲]

Noise in gene and protein expression is a major cause for bioprocess deviation. However, this phenomenon has been only scarcely considered in real bioprocessing conditions. In this work, a scaling-law derived from a genome-scale studies based on GFP reporter systems has been calibrated to an on-line flow cytometry device, allowing thus to get an insight at the level of promoter activity and associated noise during a whole microbial culture carried out in bioreactor. We show that most of the GFP reporter systems investigated and thus corresponding genes could be included inside the area covered by the scaling-law. The experimental results suggest that this scaling-law could be used to predict the dynamics of promoter activity, as well as the associated noise, in bioprocessing conditions. The knowledge acquired throughout this work could be used for the design of more robust expression systems. [less ▲]

Bernardo Dovizi, one of the most famous secretaries of the early Italian Reinassance, is best known for his literary works and for being the patron of Raffaello rather than for his endeavors in diplomacy. By deciding to follow the interests of Giovanni de’ Medici, Dovizi made some poor political decisions in his career but, in spite of this, he cunningly managed to get his patron become the Pope. The "Calandra" is a work that depicts well the author’s ideas, in between parody and classicism. From his works, Epistolario and Ricordi, it appears that the main strength of Dovizi is his irony, through which he manages to become almost an accomplice with his patron. Alongside with the iconological choice of the frescoes of his Stufetta and Loggia in the Vatican, he assumes the posture of the secretary-jester, as it was portrayed by Baldassarre Castiglione in "The Book of the Courtier": the satyr that washes into the room, used as bathroom, corresponds to the most famous pose of the patron who insists on these burlesque and mocking characteristics, although relating to Ovid and Plato. Bibbiena seems to be aware of how much the man that exceeds in praise himself appears unbearable, therefore, in his relations with members of the ruling class, he often assumes a playful attitude. In the Rome of Leo X, because of the Socratic 'serio ludere', such attitude was accepted and admired. The best instruments of Bibbiena are the pleasantness and a careful selection of humanistic ideals. Such ideals were those that suited better the environment in which he, the courtier, had to operate, and were used in his works. [less ▲]

Dopo una introduzione storica e storiografica sul significato dei culti regali ellenistici, l’intervento esamina alcuni dei nomi divini attribuiti ad Arsinoe II nelle fonti letterarie e documentarie, con l’eccezione dell’epiclesi esclusiva Philadelphos. Scopo della ricerca è 1) una valutazione delle strategie di inserimento della nuova dea nel pantheon tradizionale; 2) una riflessione sull’autoconsapevolezza degli antichi in relazione alla propria tradizione religiosa, per come essa si manifesta attraverso l’oculata manipolazione di un elemento essenziale nella definizione della divinità, qual è il nome divino. Un’Appendice elenca, in tre tabelle, tutte le denominazioni greche di Arsinoe II (esclusa Philadelphos), fornendo indicazioni sulla fonte, la sua collocazione spaziale e temporale e sulla divinità tradizionale di riferimento.

En 140/39 av. J.-C., une mission romaine composée, entre autres, de Scipion Emilien et du philosophe Panétios visita les alliés orientaux de Rome et se rendit notamment à Alexandrie. Le roi Ptolémée VIII y accueillit officiellement ces hôtes prestigieux, vêtu d’un habit étrange : un chiton long et subtil, dont les auteurs anciens réfèrent unanimement l’effet efféminé et caricatural, au point de susciter le rire des Romains et une condamnation du luxe effréné et décadent du royaume égyptien par comparaison avec la sobriété romaine. Il a fallu attendre une étude de H. Heinen en 1983 pour reconnaître, d’une part, l’envergure idéologique du lien entre la tenue de Ptolémée VIII – en fait empruntée à l’iconographie hellénistique de Dionysos – et la mise en scène officielle de la tryphè et du pouvoir royal et, de l’autre, le sens politique de la représentation caricaturale qu’en donna probablement déjà Panétios, représentation qui fut relayée et amplifiée par toute une tradition historiographique philo-romaine, qui se développa tout au long de la conquête romaine de la Méditerranée et ensuite à l’occasion du conflit entre Octavien et Antoine. Cette tradition nous a transmis, par le biais des auteurs de l’époque impériale, un discours fondé sur l’opposition entre Rome (et l’Italie), vertueuse source de citoyens et de soldats, et l’Orient dégénéré. Dans un tel cadre, Dionysos et le dionysisme sont sollicités pour servir à la construction d’un modèle accusatoire contre les ennemis de Rome, incarnant le désordre dans une dimension à la foi individuelle et institutionnelle. Mais est-ce que cette vision idéologique nous donne un portrait satisfaisant des rapports réels entre Rome et Dionysos / Bacchos / Liber Pater ? En partant de cette question, je propose dans ma contribution une approche visant à analyser, à l’aide de sources aussi littéraires que documentaires, les contextes de contact entre Rome et Dionysos de l’époque hellénistique au début du Principat, pour essayer de mettre en relief les relations entre, d’une part, la répulsion et le refus idéologiques du dionysisme, de l’autre les démarches d’appropriation et d’adaptation, à la culture romaine, de traits caractérisant les cultes hellénistiques de Dionysos et leurs utilisation dans la mise en forme des pratiques du pouvoir et de leurs représentations.

Scientists in many fields of research have developed models, theories and concepts attempting to grasp and manage dangers that are often difficult to imagine. Among the different perspectives, the Science and Technology Studies (STS) Vulnerability Approach seems very promising. Relying on a constructivist paradigm, it is based on an inductive collection and analysis of a wide range of factors, with a particular focus on cultural factors and actual day-to-day practices. In this paper, we present the roots of this approach and we display findings based on three case studies exploring emergency planning in three different contexts (a city near a SEVESO plant, a school near a nuclear plant, and a city confronted to multiple catastrophic scenarios). The cases studies were realized by conducting three Focus Groups with different types of stakeholders (citizens, teachers, firemen, decision makers, etc.). After presenting the results of the case studies, we discuss how stakeholders’ participation can inform such type of vulnerability analysis in the context of emergency planning. We argue that participation fosters a deep understanding of actual safety governance practices which allows innovative results to emerge as well as it initiates a learning process among the participants. It contributes to questioning the relations between decision-makers, experts and citizens. It has the potential of bypassing the positivist and quantitative rationale of safety, and thus, of redefining the vulnerability governance. As a conclusion, we question the role of such STS vulnerability approach within the actual vulnerability governance. [less ▲]
