Dynamics of Strongly Coupled Modes between Surface Plasmon Polaritons and Photoactive Molecules: The Effect of the Stokes Shift

2017

We have investigated the dynamics of strongly coupled modes of surface plasmon polaritons (SPPs) and fluorescent molecules by analyzing their scattered emission polarization. While the scattered emission of SPPs is purely transverse magnetic (TM) polarized, the strong coupling with molecules induces transverse electric (TE) polarized emission via the partial molecular nature of the formed SPP–molecule polariton mode. We observe that the TM/TE ratio of the polariton emission follows the contribution of the molecular excited states in this hybrid mode. By using several types of molecules, we observe that, in addition to the coupling strength, which determines the contribution of the molecular…

Minerva y la reformulación de la masculinidad en "Cristalián de España" de Beatriz Bernal

2010

La literatura artúrica exhibe, por lo general, no sólo una visión patriarcal de las relaciones sociales, políticas y amorosas sino también una perspectiva masculinista de los personajes. Esta representación narrativa resalta el poder, protagonismo y virilidad de los héroes masculinos y, en contrapartida, la fragilidad y pasividad de los personajes femeninos. Este convencional patrón narrativo, no obstante, es reinventado y reformulado en el libro de caballerías Historia de los invictos y magnánimos caballeros don Cristalián de España, Príncipe de Trapisonda, y del Infante Lucescanio su hermano, hijos del famosísimo Emperador Lindedel de Trapisonda, compuesto en castellano por la autora Beat…

Preparation and physico-chemical study of inclusion complexes between idebenone and modified beta-cyclodextrins

1996

The inclusion properties of modifiedβ-cyclodextrins (trimethyl-β-cyclodextrin, dimethyl-β-cyclodextrin and hydroxypropyl-β-cyclodextrin) towards idebenone were compared with naturalβ-cyclodextrin. The inclusion complexes were prepared by different methods (coprecipitation, kneading, and freeze-drying) and characterized by differential scanning calorimetry, X-ray diffractometry, UV, CD and NMR spectroscopy. The results obtained by CD and NMR spectroscopy indicate a different orientation of idebenone in dimethyl-β-cyclodextrin with respect to other cyclodextrins. Stability constants of the complexes were determined in water at various temperatures and consequently thermodynamic parameters wer…

Detección de cambios anómalos mediante teledetección

2016

Este trabajo de fin de máster aborda el problema de la detección automática de cambios anómalos ocurridos en la superficie terrestre mediante imágenes satelitales de la Tierra. Dichos cambios implican cualquier variación fuera de lo típicamente esperado que se produzca en un área determinada del planeta. Su detección es muy importante dentro de las ciencias de la Tierra, ya que en el contexto actual de calentamiento global y cambio climático, presentan una importancia muy elevada en la escala global y local, permitiendo descubrir nuevos efectos generados por las actividades humanas que alteren el medio natural, y también posibles desestabilizaciones a gran escala entre los sistemas terrestr…

Ratures fécondes

2012

Commenting on daily life of the scientific community, newspapers highlight some characteristics of the way sciences are evolving, thanks to a kind of epistemological flash-back : the way they lean on working hypothesis, these working hypothesis leaning themselves on on-going dogma. These comments on scientific current affairs call for a new understanding of gradual corrections of hypothesis.

Photoactive Yellow Protein Chromophore Photoisomerizes around a Single Bond if the Double Bond Is Locked

2020

Photoactivation in the Photoactive Yellow Protein, a bacterial blue light photoreceptor, proceeds via photo-isomerization of the double C=C bond in the covalently attached chromophore. Quantum chemistry calculations, however, have suggested that in addition to double bond photo-isomerization, the isolated chromophore and many of its analogues, can isomerize around a single C-C bond as well. Whereas double bond photo-isomerization has been observed with x-ray crystallography, experimental evidence for single bond photo-isomerization is currently lacking. Therefore, we have synthesized a chromophore analogue, in which the formal double bond is covalently locked in a cyclopentenone ring and ca…

Influence of pasteurization temperature on flesh firmness of table olives cv. Nocellara del Belice

2013

The application of heat treatment is especially important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. The aim of this study was to evaluate the influence of pasteurization time and temperature on the flesh firmness of table olives cv. Nocellara del Belice, packaged in glass jars, and to study their effect on the microbial community of table olives. Four different treatments were applied, one for each of the pasteurization temperatures adopted: 65 °C, 75 °C, 85 °C and 95 °C. A control test was also carried out (test Tc, not pasteurized). Each test was repeated with treatment…

Utilidad de la ecografía abdominal en la valoración de la respuesta al tratamiento médico con fármacos inmunomoduladores y/o biológicos de la Enferme…

2022

Las técnicas de imagen presentan, frente a la endoscopia, la ventaja de no ser invasivas y han sido aplicadas con éxito en la valoración clínica de múltiples aspectos de la enfermedad de Crohn (EC). La ecografía abdominal (EA), es una técnica que ya ha demostrado su valor en el diagnóstico de la EC y de sus complicaciones cómo fístulas y abscesos. Además, presenta sobre las otras técnicas de imagen, las ventajas de la ausencia de radiación, fácil accesibilidad y bajo coste. Algunos estudios han observado mediante el uso de técnicas de imagen que la curación transmural se asocia a un pronóstico favorable a largo plazo, superior al conseguido por la curación mucosa o la ausencia de curación, …
