Antimicrobial and Antioxidant Activities of Coumarins from the Roots of Ferulago campestris (Apiaceae)

2009

We report the isolation of several coumarins and the stereochemical assessment of some pyranocoumarins, as well as the antibacterial and antioxidant activities of the three most abundant ones (grandivittin, agasyllin and aegelinol benzoate) isolated from the roots of Ferulago campestris collected in Sicily and of the hydrolysis product (aegelinol). Aegelinol and agasyllin showed antibacterial activity against nine ATCC and the same clinically isolated Gram-positive and Gram-negative bacterial strains. At a concentration between 16 and 125 μg/mL both coumarins showed a significant antibacterial effect against both Gram-negative and Gram-positive bacteria. In particular the ATCC strains Staph…

La transparence, nouveau régime visible

2005

International audience; La transparence comme figure sensible Dans sa relation dialectique au secret, la transparence a toujours nourri un discours sur l'éthique de la communication. Pour autant, à voir toutes les formes d'expression de la transparence, tout son champ d'extension sensible, ce n'est pas seulement une valeur mais une figure des temps post-modernes, certains diront « hypermodernes », qu'il nous faut explorer. La dimension éthique s'ouvre alors sur l'univers esthétique de la communication, c'est-à-dire la reconnaissance de formes associées à la transparence et les modes de relation qu'elles favorisent en termes de communication, sans laisser dominer telle norme de jugement ou t…

Saveurs rhétoriques : de la mise en mots à la mise en bouche. Vers une trinité du sensible?

2015

International audience; Cet article analyse le fonctionnement des figures de rhétorique dans l’univers culinaire et gastronomique. Mais il ouvrira la réflexion en suggérant que celles-ci donnent du goût à l’énoncé, entendons qu’elles deviennent figures du sensible. Reconnaitre les figures comme processus participant pleinement à la construction du discours culinaire nous conduira à les envisager comme l’émergence d’un processus sémiotique du sensible.

Objet et préfiguration

2010

We call prefigurative an object whose primary function is to allow whoever manipulates it to represent an object, a situation, an action that has not yet happened ; the prefigured object is particular because it not only exists to convey meaning but also to inform, to get us to believe and finally to make us act. This article aims to outline the semiotic analysis of one of these objects, the restaurant menu: leaving aside the verbal text, we shall examine the material object which is its support (paper, cardboard, slate, screen, etc..) and see that it directs our receptions and predisposes us by its material, its size, its touch, its typography and its layout to perceive the true taste of t…

A ‘Fortuitous’ Imagination. Josef Frank. Thirteen Fantasy Houses for Dagmar Grill

2017

Between 22 July and 15 August 1947 Josef Frank wrote thirteen letters to Dagmar Grill, cousin of his wife, met in 1914 in Stockholm. The letters contain several hypothesis for an ideal house to be built in Skargarden, an archipelago to the east of Stockholm, where Dagmar Grill lived. Every letter contains sketches and schemes for an imaginary house. The thirteen projects refer to identical functional needs, but differ each other in shape and size. Although they are “fantasy” houses, the sketches refer to a real imaginative exercise rather than to a simple figurative/compositional exercise.

Embeddings of graph braid and surface groups in right-angled Artin groups and braid groups

2003

We prove by explicit construction that graph braid groups and most surface groups can be embedded in a natural way in right-angled Artin groups, and we point out some consequences of these embedding results. We also show that every right-angled Artin group can be embedded in a pure surface braid group. On the other hand, by generalising to right-angled Artin groups a result of Lyndon for free groups, we show that the Euler characteristic -1 surface group (given by the relation x^2y^2=z^2) never embeds in a right-angled Artin group.

Heterogeneous Photocatalysis for Selective Formation of High-Value-Added Molecules: Some Chemical and Engineering Aspects

2018

This review deals with the parameters that influence heterogeneous photocatalysis (PC) for selective synthesis of high-value chemicals by itself or in combination with other technologies. In particular, the parameters related to the photocatalysts, such as crystallinity degree, type of polymorph, surface acid-base properties, exposure of particular crystalline facets, coupling of different semiconductors, position of the valence and conduction band edge, addition of doping agents, and those related to the reaction system, such as setup configuration and reactor geometry, type of solvent, type and amount of photocatalyst, affecting the selectivity toward specific products are described and d…

Le opere esposte da Maria Accascina alla Mostra d’Arte Sacra delle Madonie

2017

Il saggio espone i metodi e gli strumenti di ricerca utilizzati per la ricostruzione del catalogo della pioneristica Mostra D’Arte Sacra delle Madonie curata da Maria Accascina ed allestita nel 1937 presso il Convento dei PP. Riformati di Petralia Sottana, centro delle alte Madonie. Si tratta di più di quattrocento opere, tra gioielli, suppellettili liturgiche, oggetti preziosi di uso profano, coralli, paramenti sacri, tessuti, statue lignee, intagli, maioliche, tappeti, tele e tavole dipinte realizzate dal XI al XIX secolo. Le opere, alcune delle quali perdute, provengono dalle collezioni nobiliari, dall’allora Museo Nazionale di Palermo, ora Galleria Regionale della Sicilia, Palazzo Abate…
