Modulational instability and domain wall solitons in optical fibers

2000

The first part of this thesis presents some theoretical and experimental results about modulational instability and domain wall solitons in bimodal fibers.In the second part is devoted to the interaction of counter-propagating waves in an isotropic optical fiber

Enhanced proinflammatory response to the Candida albicans gpi7 null mutant by murine cells.

2008

International audience; The Candida albicans gpi7/gpi7 null mutant strain (Deltagpi7), which is affected in glycosylphosphatidylinositol (GPI) anchor biosynthesis, showed a reduced virulence following systemic infection of C57BL/6 mice. In vitro production of TNF-alpha, IL-6 and IL-1beta by macrophages in response to Deltagpi7 cells was significantly increased as compared to control (wild type GPI7/GPI7 and revertant gpi7/GPI7) cells; this probably contributes to the enhanced recruitment of neutrophils to the peritoneal cavity in response to Deltagpi7 cells. Survival of knockout mice for Toll-like receptor (TLR) 2 and TLR4 following intravenous injection of Deltagpi7 cells showed no signifi…

Exemples de conservation de bois : trois types d’aménagements funéraires du VIIe au XVIIIe siècle à Thaon (Calvados)

2009

The excavations started inside and in the immediate neighbourhood of the roman church Saint-Pierre of Thaon since 1998 have enabled to underline several phases of occupation between the IInd century AD and the XIIth with, from the VIIth century, the establishment of a church modified repeatedly. Among 437 burials (from VIIth to XVIIIth century), devices combining wood and stones (cofferings) or showing important remains of wood perfectly preserved (whole boards of coffin nailed down and pegged) were studied and are presented in this article.

Trésors et trésoriers des paroisses de Rouen (1450-1530)

1991

Owing to the collections more andmore profitable, to the foundations of perpetual masses, particularly numerous in the 1480-1510 period, the rouennais churchwardens have substantial financial resources that they use in a vast programme of reconstruction of the places of worship, some purchases of somptuous vestments and some interest loans. Playing so a not insignificant part in the economy of the town, they are recruited from amogn the greatest families, who consolidate their prestige and their influence by a luxurious piety for the profit of their parish.

L'utilisation des reliefs naturels dans l'art gravé et sculpté pariétal du paléolithique supérieur français

2005

Pendant toute la durée du Paléolithique supérieur, en Espagne et en France principalement, les artistes ont réalisé des figurations en utilisant les reliefs naturels et la morphologie des parois de grottes ou d'abris-sous-roche. Ce phénomène artistique, qui a toujours préoccupé les préhistoriens, a suscité les interrogations et les interprétations les plus diverses de la fin du XIXe siècle jusqu'à présent : origine de l'art, préoccupations magico-religieuses, organisation spatiale et sanctuarisation de l'espace souterrain, structures pariétales, chamanisme, techno-cultures, etc. Pendant longtemps, ce que les formes rocheuses pouvaient avoir d'évocateur a été considéré comme la raison d'être…

A new species of Thilachium (Capparaceae) from the Analanjirofo Region, Madagascar

2023

Madagascar is a centre of speciation for the genus Thilachium Lour., which includes several species of small trees and shrubs occurring in a wide range of habitats. A new species of Thilachium, T. latifolium Fici, from the Analanjirofo Region of northeastern Madagascar is here described and illustrated. It is characterised by 1-foliolate leaves, leaf blades widely ovate or elliptic with shortly acuminate or acute apices, flowers in terminal, dense subumbels or corymbs, short pedicels and ellipsoid, ribbed fruit. The new species is related to T. madagascariense Fici, a species recently described from eastern Madagascar, differing in the wider, coriaceous leaves with shorter, mucronulate tip,…

Research on regular priories, monastic and canonic in the formes dioceses of Chalon and Mâcon from the 10th to the 14th centuries

2013

The study presented here is the result from an inventory of the priories in the former dioceses of Chalon and Macon, closely dependent on the metropolis of Lyon .This territory corresponds to the main roads of the former realm of Burgundy. Among the 183 priories which have been retained, only 69 depended on Cluny, all the others belonged to the other monastic or canonic families of St Augustine’s order. The majority of these priories was mentioned for the first time by sources from late ninth and beginning of tenth century.The data collected have allowed to draw a map of the implanted sites in the form of a poster attached to the thesis and an index of the sources which are, for the most pa…

Self-polarization of light in optical fibers

2015

The second performs the first experimental demonstration of the polarization domain walls which cancel the effects which degrade the intensity and spectral profile of a telecom signal during propagation. This phenomenon comes from non-linear coupling between the two orthogonal polarization modes of light propagating in a Kerr medium in normal dispersion regime, and causes a modulation in phase opposition of the two modes along the fiber. It is possible to lock two optical pulse trains complementary intensity so that the pulses do not suffer the effects of distortion occurring in the fiber in order to maintain the information to be transmitted. And a distortion-free propagation was achieved …
