Interaction en champ proche entre une sonde nanométrique et le champ de composants à cristal photonique:- interaction faible, microscopie spatialemen…
2008
With the improvement of fabrication techniques, the nanophotonics and more especially the photonics crystals which are periodic structure at the Wavelength scale have been recently developed. In this work, by using a scanning near-field optical microscope, we study such components. Firslty, we use the local probe to visualize the light distribution inside photonic crystal microcavities etched into semiconductor III/V. We focus us on the explanation of the near-field maps formation and on the probe influence on these maps. Thus, we have visualize degeneracy splitting of optical cavity modes and clearly observed in near-field cavity modes which were not visible in far-field. Moreover, in the …
Etude en champ proche et en champ lointain de composants périodiquement nanostructurés : cristaux photoniques et tamis à photons
2004
Recently, a new class of optical components is appeared. Its main characteristic is to be formed by a periodical sub-wavelength pattern, leading to the apparition of a spectral domain where propagation of light inside the structure is forbidden -- a photonic bandgap. This work is devoted to the study in the near- and far-field of two kinds of periodical optical components: photonic crystals (PCs) and nanostructured metallic films that exhibit the so-called enhanced transmission. First, we study two-dimensional PCs with a scanning near-field optical microscope (SNOM) in collection mode. With this SNOM, we directly map the intensity distribution inside PC-based microcavities. We also evidence…
From ‘Sedate' to ‘Rotten': the Role of Books in the Genesis of The Power and the Glory
2007
This paper traces the references to books in Greene's Journey Without Maps, The Lawless Roads and The Power and the Glory in order to map out the writer's journey to the origins of writing – counter to the priest's itinerary in the latter novel.
Body Politics and Fat Shaming
2020
Fat shaming as a concept captures all the bias ingrained in cultural values, economic orders, and hegemonic ideals that stigmatize overweight or obese bodies. From a cultural perspective, media analysis of fat shaming allows us to address the body stratification that societies have produced, that is, what now is generally known as a somatic order. The entry analyzes the cultural effects of normalization and body politics.

A posteriori error estimates for variational problems in the theory of viscous fluids
2016
The papers included in the thesis are focused on functional type a posteriori error estimates for the Stokes problem, the Stokes problem with friction type boundary conditions, the Oseen problem, and the anti-plane Bingham problem. In the summary of the thesis we consider only the Oseen problem. The papers present and justify special forms of these estimates which are suitable for the approximations generated by the Uzawa algorithm. The estimates are of two main types. Estimates of the first type use exact solutions obtained on the steps of the Uzawa algorithm. They show how errors encompassed in Uzawa approximations behave and have mainly theoretical meaning. Estimates of the second type o…
Honeybees affect floral microbiome composition in a central food source for wild pollinators in boreal ecosystems
2021
AbstractBasic knowledge on dispersal of microbes in pollinator networks is essential for plant, insect, and microbial ecology. Thorough understanding of the ecological consequences of honeybee farming on these complex plant–pollinator–microbe interactions is a prerequisite for sustainable honeybee keeping. Most research on plant–pollinator–microbe interactions have focused on temperate agricultural systems. Therefore, information on a wild plant that is a seasonal bottleneck for pollinators in cold climate such as Salix phylicifolia is of specific importance. We investigated how floral visitation by insects influences the community structure of bacteria and fungi in Salix phylicifolia inflo…
Silenciamiento sistémico inducido por pequeños RNAs artificiales en Nicotiana benthamiana
2020
Los pequeños RNAs (sRNAs), microRNAs (miRNAs) y sRNAs de interferencia (siRNAs), degradan específicamente moléculas de RNA de secuencia complementaria, proceso conocido como silenciamiento génico. En algunos casos, los miRNAs de 22 nucleótidos inducen la producción de siRNAs secundarios a partir sus RNAs diana, y estos siRNAs secundarios se desplazan por la planta a corta y larga distancia propagando el silenciamiento. Experimentos previos mostraron que la expresión transitoria en hojas de Nicotiana benthamiana del miRNA artificial (amiRNA) amiR-NbSu-2 de 21 nucleótidos frente al gen SULPHUR inducía silenciamiento sistémico (SS) en hojas jóvenes no agroinfiltradas, además de silenciamiento …
Study of scintillation light collection, production and propagation in a 4 tonne dual-phase LArTPC
2020
The $3 \times 1 \times 1$ m$^3$ demonstrator is a dual phase liquid argon time projection chamber that has recorded cosmic rays events in 2017 at CERN. The light signal in these detectors is crucial to provide precise timing capabilities. The performances of the photon detection system, composed of five PMTs, are discussed. The collected scintillation and electroluminescence light created by passing particles has been studied in various detector conditions. In particular, the scintillation light production and propagation processes have been analyzed and compared to simulations, improving the understanding of some liquid argon properties.
