Singlet oxygen-based photocatalytic oxygenation reactions have emerged as an efficient technology to synthesize value-added organic molecules. Among organic substrates, bio-sourced molecules such as aminoacids or terpenes have a promising forecast as synthetic building blocks. A pseudo first-order kinetic study for the photocatalytic oxygenation of natural amino acid (L)-methionine was carried out in a macroscopic batch reactor. Various parameters were studied, including the effect of the photosensitizer (Rose Bengal, RB) concentration, the intensity of the light and the O2 flow in terms of apparent kinetic constants and space-time yields. The identification of important limiting parameters as pressure, gas flow or light efficiency during the photocatalytic oxygenation of methionine allowed its transition from macroscopic batch reactor to continuous-flow microreactor.

Fixité et mouvement coexistent fréquemment dans l’imagerie antique. Les Blattmasken en sont la parfaite illustration, car ils se caractérisent à la fois par une frontalité presque exemplaire et par un dynamisme végétal insufflé par les feuilles dont ils sont composés. Les quatre exemples choisis pour illustrer ce propos correspondent chacun à une formule particulière d’intégration des têtes végétalisées dans leur environnement immédiat. Celles-ci peuvent en effet être isolées de tout contexte végétal, intégrées dans un décor de rinceaux, ou encore structurellement liées à celui-ci en lui donnant naissance ou en émergeant de l’une de ses volutes. Cette forme de végétalisation de la figure humaine semble se rattacher à une hybridation plutôt qu’à une métamorphose. Cette fusion des règnes humain et végétal révèle une symbolique complexe qu’il conviendra de préciser. [less ▲]

La Blattmaske ou tête végétalisée est un motif romain apparu au Ier siècle apr. J.-C. Elle ne cessa d’être utilisée dans l’univers des formes , et donc de se renouveler. Mais il est un milieu qui constitue un jalon important dans l’histoire de son utilisation : la Rome de l’époque carolingienne. Après une rupture de près de quatre siècles dans la mise en oeuvre italique du motif, le remploi de fragments du temple de Sol Invictus semble en effet être à l’origine d’un certain regain d’intérêt pour le sujet dans des églises romaines du IXe siècle. Bien qu’il ne soit pas toujours aisé de distinguer des originaux antiques spoliés, parfois retravaillés, de créations médiévales, l’examen des fragments et de leur contexte permet de préciser leur origine et leur signification.

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 ▲]

Blattmasken belong to vegetalized human figures used in parietal decoration of nymphaei and domestic ponds. Their use depends on the process of iconographic forms’ transmission already highlighted between the parietal mosaic, the italic mural painting of Ist century a.C. and the African ground mosaic. This transfer is discussed in the light of two cases : the House of Neptune and Amphitrite at Herculanum and the House of the Nymphs at Neapolis. The study is based on their iconographical environments and on their typology. It highlights two different symbolic conceptions of the motive. [less ▲]

Dietary fiber (DF) has many positive effects on human health associated with its functionality in the gastrointestinal tract. These benefits vary according to the type of DF. Vegetables can be a natural source of DF in the diet. However, to provide adequate nutritional advice, the content and profile of their various DF types must be characterized. This study aimed to determine the DF profile of 29 vegetables cultivated in Wallonia (Belgium) and the impact of steaming on these profiles. Using a combination of enzymatic, gravimetric and chromatographic methods, fructans, total dietary fiber (TDF), low- and high-molecular-weight soluble dietary fiber (SDF), and insoluble dietary fiber (IDF) were analyzed. Results show that the DF content varies considerably among the 29 investigated vegetable varieties and species, but the influence of steaming is limited to a shift from IDF to high-molecular-weight SDF for 18 of the 29 tested vegetables, while fructans are preserved with not actual reduction in the DP.

In the eighteenth century, literary journals have set a specific relationship with their readers. By publishing letters from the public and by answering to their demands (or not), the journalists have established a readers’ community that share a common cultural universe. This article aims at analyzing the relationship between the antiphilosophe François-Xavier de Feller and the readership of his Journal historique et littéraire. The journalist, who wishes to fight against the philosophes and to spread his own radical ideas above all, has however taken his public’s capacity of reaction into account. This article will question the mechanisms of this relationship by considering the letters from the public to the editor but also Feller’s own addresses to his readership published in the journal. Even if he refuses the idea that every man is able to use his own critical reason, the journalist has been influenced by his readership but, more importantly, he has maintained in his public a new form of criticism, radically opposed to the ideas of Enlightenment.

Les services publics de l’emploi ont délégué leur mission d’accompagnement des chômeurs aux prestataires de service. L’article s’intéresse au déroulement des collaborations entre services publics et opérateurs privés d’emploi, en Belgique et en Suisse. Ces partenariats sont confrontés à deux épreuves qui sont le recrutement des candidats dans les projets de formation et la mesure des résultats de la prestation. Notre hypothèse initiale soutient l’idée que les jeux d’acteurs ont plus d’effet dans la résolution des situations critiques que le cadre de collaboration. La comparaison internationale nous permet de faire varier les modalités de création des partenariats et de montrer une articulation particulière entre jeux d’acteurs et cadre de collaboration.

Objectives: To examine beliefs about cracking sounds heard during highvelocity lowamplitude (HVLA) thrust spinal manipulation in individuals with and without personal experience of this technique. Methods: We included 100 individuals. Among them, 60 had no history of spinal manipulation, including 40whowereasymptomatic with or without a past history of spinal pain and 20whohad nonspecific spinal pain. The remaining 40 patients had a history of spinal manipulation;amongthem, 20 were asymptomatic and 20 had spinal pain. Participants attended a oneonone interview during which they completed a questionnaire about their history of spinal manipulation and their beliefs regarding sounds heard during spinal manipulation. Results: Mean age was 43.5±15.4 years. The sounds were ascribed to vertebral repositioning by 49% of participants and to friction between two vertebras by 23% of participants; only 9% of participants correctly ascribed the sound to the release of gas. The sound was mistakenly considered to indicate successful spinal manipulation by 40% of participants. No differences in beliefs were found between the groups with and without a history of spinal manipulation. Conclusions: Certain beliefs have documented adverse effects. This study showed a high prevalence of unfounded beliefs regarding spinal manipulation. These beliefs deserve greater attention from healthcare providers, particularly those who practice spinal manipulation. [less ▲]
