Combining reformulation, active packaging and non-thermal post-packaging decontamination technologies to increase the microbiological quality and saf…

2018

Abstract Background Cooked ready-to-eat (RTE) meat products are subjected to contamination of spoilage microorganisms such as lactic acid bacteria and pathogens such as Listeria monocytogenes. These microorganisms contaminate cooked RTE meat products after the cooking step and may further grow during shelf-life potentially leading to spoilage or foodborne diseases, respectively. In the current context of salt, fat and chemical preservatives reduction in meat products formulations, a combined strategy that considers the development of more robust formulations, active packaging and the use of non-thermal post-packaging decontamination strategies seems required to ensure shelf-stable and safe …

Capillary electrophoresis–inductively coupled plasma-mass spectrometry hyphenation for the determination at the nanogram scale of metal affinities an…

2012

Abstract A screening strategy based on hyphenated capillary electrophoresis and inductively coupled plasma mass spectrometry (CE–ICP-MS) was developed to classify phosphorylated ligands according to their europium(III) binding affinity in a hydro-organic medium (sodium formate, pH 3.7, H2O/MeOH 90:10, v/v). Taking advantage of the high sensibility of ICP-MS for detecting phosphorus, this method enabled to assess the affinity of a variety of phosphorylated compounds, including phosphine oxides, thiophosphines, phosphonates, and phosphinates, in less than 1 h and using less than 5 ng of substance. By varying the total europium concentration, complexation constants could be determined accordin…

Negociación y conflicto colectivo en Francia

2013

International audience; Available online: https://roderic.uv.es/bitstream/handle/10550/30246/arxius28.pdf_pag21-28.pdf?sequence=1&isAllowed=y This paper aims at analyzing the relations between collective bargaining and trade disputes, two capital pillars of Labour and Employment Law. If strike has traditionally been considered as an instrumental mechanism for collective bargaining, this paper shows how this claim does not stand for France, where these two key institutions keep a different relationship, in which collective bargaining is being given the role of preventing or reducing the impact of the strike.; Available online: https://roderic.uv.es/bitstream/handle/10550/30246/arxius28.pdf_p…

A quoi sert le ministre du Travail ? Compte rendu de F. Rebsamen, En toutes confidences (Stock, 2016)

2017

François Rebsamen a été ministre du Travail en 2014-2015. Son livre, En toutes confidences, revient sur cette expérience ministérielle et plus largement sur son itinéraire politique. Son propos parfois incisif fait tout son intérêt. En outre, rares sont les ministres du Travail qui ont témoigné de leur rôle et l’ont fait sans trop de langue de bois. Le livre constitue donc une plongée dans l’univers des négociations avec les partenaires sociaux au plus haut niveau, de la fabrique ou du bricolage de réformes, puisque l’ancien ministre a laissé son nom à une loi relative au dialogue social et à l'emploi.

Internal photoemission in solar blind AlGaN Schottky barrier photodiodes

2005

We have analyzed the photoresponse of solar blind AlGaN Schottky barrier photodiodes below the alloy band gap energy, in the 3.5-4.5 eV range, and we show that it is dominated by internal photoemission. The n-type Schottky barrier height is shown to increase linearly with the band gap energy of the AlGaN alloy. The amplitude of the internal photoemission signal is about 20 times smaller than the value given by the Fowler theory based on a free electron model. We explain this result by taking into account the interband transitions and the ballistic transport of photoexcited electrons in the metal. This low value of internal photoemission allows us to achieve a spectral rejection ratio betwee…

Towards a test of the weak equivalence principle of gravity using anti-hydrogen at CERN

2016

International audience; The aim of the GBAR (Gravitational Behavior of Antimatter at Rest) experiment is to measure the free fall acceleration of an antihydrogen atom, in the terrestrial gravitational field at CERN and therefore test the Weak Equivalence Principle with antimatter. The aim is to measure the local gravity with a 1% uncertainty which can be reduced to few parts of 10-3.

Ultraviolet vision and foraging in terrestrial vertebrates

2002

Tetrachromatic colour vision, based on four ‘main’ colours and their combinations, is probably the original colour vision in terrestrial vertebrates. In addition to human visible waveband of light (400–700 nm) and three main colours, it also includes the near ultraviolet part of light spectrum (320–400 nm). The ecological importance of ultraviolet (UV) vision in animals has mainly been studied in the context of intra- and inter-sexual signalling, but recently the importance of UV vision in foraging has received more attention. Foraging animals may use either UV cues (reflectance or absorbance) of food items or UV cues of the environment. So far, all diurnal birds studied (at least 35 specie…
