A GLIMPSE OF THE SPECTRAL WOMAN: ROMANTIC BALLET AND THE GOTHIC

The age of romantic ballet – especially in its focal point, the Paris Opéra between 1831 and 1845 – is known for signalling the rise of the ballerina from entertainer to cultural icon. She was the heroine of fantastic stories in which the surface of reality was cracked, allowing a glimpse of other worlds populated by supernatural female characters; an incarnation of the sublime, idolised by audiences and critics. Yet, there was a brutal contrast between the dazzling perception of the stars and the workaday reality of most ballerinas. Romantic ballets often explored the limited possibilities for women in French society, and sometimes even presented otherworldly alternatives through the use of Gothic elements. This article explores how an image of delicate, spectral femininity was constructed on the Parisian stage and press, and to what extent the characters of romantic ballet – and the women portraying them – could be dancing against that same imagery

Synthesis and Spectroscopic Behavior of Some Oxovanadium(IV) and Oxovanadium(V) Complexes of 7-Iodo-8-Hydroxyquinoline-5-Sulfonate

The oxovanadium (IV) complex [VOL2].5H2O (1) and the oxovanadium(V) complexes K[VOL2O].4H2O) (2), [VOL2OH] (3) and [VOL2OCH3] (4) (L = potassium salt of 7-iodo-8-hydroxyquinoline-5-sulfonic acid) were prepared and characterized. The IR spectra of the solids were recorded and discussed in comparison with those of other similar compounds. The electronic absorption spectra, in different solvents, were also analyzed. Pre-resonance Raman measurements, performed with the first two mentioned complexes, reinforce some of the spectroscopic assignments.Centro de Química Inorgánic

Biodegradation and Mechanical Integrity of Magnesium and Magnesium Alloys Suitable for Implants

This book chapter deals with the fundamental aspects of corrosion of magnesium based alloys in bodily fluids and reviews the various techniques that can be used to tune their degradation rate. The time-dependent evolution of their mechanical properties during the biodegradation process is also outlined

Effect of fenitrothion on dipalmitoyl and 1-palmitoyl-2-oleoylphosphatidylcholine bilayers

The effects of the organophosphorous insecticide fenitrothion (phosphorothioic acid, O,O-dimethyl O-(3-methyl-4-nitrophenyl) ester; FS) on the physical state of pure dipalmitoyl (DPPC) and 1-palmitoyl-2- oleoylphosphatidylcholine (POPC) membranes were investigated. FS lowers the phase transition temperature of DPPC. It has no large effects on the DPPC gel phase, but it increases the order of the liquid-crystalline state of DPPC and POPC. FS also decreases 1,6-diphenyl-1,3,5-hexatriene (DPH) lifetime (τ) in the DPPC and POPC liquid-crystalline states. Since a direct quenching of DPH emission by FS was ruled out, τ shortening is assigned to an increased water penetration in the bilayer. The effect of FS is different from most perturbing agents for which an increased order is accompanied by a higher τ. Furthermore, quenching of DPH by KI was increased by FS in POPC liposomes indicating an increased accessibility of the quencher to the hydrophobic core where DPH distributes. The effect of FS on dipole relaxation at the hydrophilic-hydrophobic interface of POPC bilayers was studied with 2- dimethylamino-6-lauroylnaphthalene (Laurdan). FS produces a decrease in Laurdan τ and a narrowing of its emission band. FS significantly increases the generalized polarization values at both emission band ends. These results indicate that FS may allow the coexistence of microdomains that have different physical properties.Facultad de Ciencias MédicasInstituto de Investigaciones Bioquímicas de La Plat

UV/Vis spectroelectrochemistry of o-vanillin: Study of the antioxidant properties

UV/Vis absorption spectroelectrochemistry is a very useful technique to study complex electrochemical mechanisms. In this work, we have studied the electrochemistry of o-vanillin in presence and absence of oxygen. This compound exhibits good antioxidant properties. The products of the reaction of o-vanillin with the superoxide anion, electrogenerated when oxygen is reduced in an aprotic medium, have been detected using UV/Vis absorption spectroelectrochemistry. This technique allows us to shed more light on the antioxidant properties of o-vanillin, providing valuable information not only on the antioxidant properties of this compound but also about other compounds that follow a similar mechanism. In this work we have deconvolved the electrochemical signal in the different components that are related to the processes taking place at the electrode and in the solution adjacent to it.Ministerio de Economía y Competitividad (CTQ2017-83935-R-AEI/FEDERUE), Junta de Castilla y León (BU297P18), Ministerio de Ciencia, Innovación y Universidades (RED2018- 102412-T)
