Forte baisse de l'embauche des jeunes en Bourgogne

2010

Réalisée en Bourgogne depuis vingt-cinq ans, l'enquête Insertion dans la vie active constitue un outil particulier et unique qui donne la possibilité de suivre l'évolution des conditions d'entrée des jeunes sur le marché du travail. Cette note présente les résultats de la dernière interrogation menée en février 2009, et donne un aperçu de la transition de l'école à l'emploi. En Bourgogne, 7 400 élèves et 4 800 apprentis âgés de 20 ans en moyenne, ont été interrogés sur leur situation professionnelle. Sept mois après la fin des études, 47 % des filles et 55 % des garçons sont salarié-e-s en février 2009. Les jeunes de la région n'échappent pas à la crise économique internationale illustrée p…

De la formation à l'emploi : une transition difficile

2006

Pour connaître le devenir des anciens élèves et apprentis, le ministère de l'Éducation nationale réalise des enquêtes depuis de nombreuses années, avec l'appui des établissements scolaires et des centres de formation d'apprentis. Cette note présente les résultats des dernières enquêtes effectuées en 2005, qui appréhendent les situations des jeunes sept mois après la fin de leurs études en Bourgogne.

Circulating markers of retinal and optic nerve lipids

2013

Purpose Blood lipids are frequently used as a surrogate of lipid composition of peripheral tissues. Even if it is well accepted, such a relationship has never been clearly demonstrated for the eye. The aim of this study was to determine in human samples whether a lipidomic approach based on red blood cells could reveal associations between circulating and ocular lipid profiles. Methods Red blood cells, retinas and optic nerves were collected from 9 human donors. The lipidomic analyses on these tissues were done by both, gas chromatography and liquid chromatography coupled to an electrospray ionization source-mass spectrometer (LC-ESI-MS/MS). Results Gas chromatographic approach did not show…

Short term adaptive response of symbiotic N2 fixation in pea to root pruning of half the root system, linked to the availability of carbon assimilates

2014

Symbiotic N fixation of legumes is very sensitive to environmental stresses, like pea pests damaging nodulated roots. However, the impact on their N uptake capacity and plant growth has not been studied so far.We analyzed the adaptive response symbiotic N2 fixation and plant growth of pea wild type Frisson and hypernodulating mutants P64, P118 and P121 mutated respectively on genes SYM28, SYM29 and NOD3 to root pruning of half the root system at the end of the vegetative stage. The adaptive responses of pea: cv. Frisson and 3 of its hypernodulating mutants were compared under varying carbon supplies from photosynthesis.At 380 ppm, mutant P118 showed the lowest decrease of the specific activ…

An Ontology-Based Approach for the Reconstruction and Analysis of Digital Incidents Timelines

2015

International audience; Due to the democratisation of new technologies, computer forensics investigators have to deal with volumes of data which are becoming increasingly large and heterogeneous. Indeed, in a single machine, hundred of events occur per minute, produced and logged by the operating system and various software. Therefore, the identification of evidence, and more generally, the reconstruction of past events is a tedious and time-consuming task for the investigators. Our work aims at reconstructing and analysing automatically the events related to a digital incident, while respecting legal requirements. To tackle those three main problems (volume, heterogeneity and legal require…

A Note on Radio Antipodal Colouring of Paths

2005

International audience; The radio antipodal number of a graph G is the smallest integer c such that there exists an assignment f : V (G) -> {1, 2, . . . , c} satisfying |f(u) − f(v)| >= D − d(u, v) for every two distinct vertices u and v of G, where D is the diameter of G. In this note we determine the exact value of the antipodal number of the path, thus answering the conjecture given in [G. Chartrand, D. Erwin, and P. Zhang. Radio antipodal colorings of graphs, Math. Bohem. 127(1):57-69, 2002]. We also show the connections between this colouring and radio labelings.

Division of labor in anti-parasite defense strategies in ant colonies

2014

Division of labor is a key characteristic of social insects and contributes to their ecological success. Especially in disease defense, the intra-colony partitioning of sanitary work can reduce disease transmission, keep nestmates available for other tasks and reduce costs associated with sanitary task performance (i.e. at the behavioral and physiological level). Factors internal and external to the individual affecting sanitary task allocation are not well known and most studies investigated genetic differences between workers performing behavioral sanitary work. In the first two studies I addressed whether individual experience (through repeated exposure to a sanitary hazard or performanc…

Analysis of fluorescent MRI contrast agent behavior in the liver and thoracic aorta of mice.

2004

To characterize the behavior of magnetofluorescent products injected in mice intravenously.The magnetic resonance imaging (MRI) products were labelled with fluorescent molecules to examine the biodistribution process in vivo and observe them at the cellular level by means of confocal microscopy. Three-dimensional (3D) sequences of images were obtained by spectral analysis of sample preparations in a multiphoton confocal microscope and analyzed by the factor analysis of medical image sequence algorithm, which provides factor curves. Factor images are the result of image-processing methods that utilize information from emission spectra. Preparations are also screened in the counting mode to p…
