L’objectif du présent rapport est de présenter l’évaluation de Koha du point de vue informatique et de déterminer si il est approprié ou non pour la gestion des bibliothèques universitaires des pays partenaires de la CUD. Ce rapport se présente de la manière suivante : – L’évaluation, à travers une grille, de différents aspects techniques tels que la facilité d’installation, la stabilité, les performances, la sécurité, l’efficacité réelle des fonctions, l’interopérabilité, la structure des données, la possibilité et la facilité d’ajout de modules, la validité des aides, le paramétrage et le portage des données ; – Les annexes techniques. Ces annexes constituent un manuel thématique dans lequel chaque commande et son résultat sont décrits. Son objectif est de permettre à tout un chacun d’installer un système d’exploitation GNU/- Linux, Koha et les quelques logiciels nécessaires à son fonctionnement, sans pour autant disposer de compétences informatiques particulières.

La diversité trophique de cinq espèces d’Idotéidés associées à l’herbier et à la litière de P. oceanica (L) Delile a été étudiée en utilisant la combinaison de deux méthodes: l’analyse des contenus digestifs et la mesure des rapports isotopiques du carbone et de l’azote. Les valeurs isotopiques ont été intégrées dans un «mixing model» permettant d’évaluer les contributions relatives de sources de nourritures potentielles aux régimes alimentaires des différentes espèces. Les spécimens ont été récoltés en mars 2004 et mars 2005 à trois stations de prélèvements de la baie de la Revellata (Calvi, Corse) dans l’herbier de posidonies et dans la litière composée d’accumulation de feuilles mortes, de pousses de posidonies et de macroalgues arrachées. Cinq espèces d’Idotéidés ont été trouvées durant cette étude, Idotea baltica étant l’espèce la plus abondante. I. baltica semble restreinte à la litière de posidonies. Par contre, I. hectica, seconde espèce en terme d’abondance, fréquente à la fois les accumulations de litière et l’herbier de posidonies. Le matériel a été caractérisé (tailles, sexes, phénotypes) et 98 tubes digestifs ont été analysés. Au total 20 % des tubes digestifs étaient vides. Les résultats montrent que les espèces I. baltica, I. hectica et Zenobiana prismatica récoltés dans la litière ingèrent principalement des algues arrachées, des crustacés de la litière et des feuilles mortes de posidonies. Les espèces I. hectica et Synisoma appendiculatum prélevées dans l’herbier préfèrent les algues épiphytes mais quelques fragments de feuilles de posidonies et des diatomées sont aussi présents. L’application d’un «mixing model» suggère que les algues photophiles et épiphytes contribuent pour la majeure partie du carbone assimilé chez ces espèces (gamme de 0 jusqu’à plus de 80 %). La part des crustacés est importante chez I. baltica, ce qui traduit une plus grande diversification du régime alimentaire chez cette espèce, tendance qui s’accentue avec l’âge des individus. I. hectica montre un comportement plus sélectif et dirigé vers la flore épiphyte ou les algues arrachées. Les feuilles mortes de P. oceanica n’interviennent que pour une très faible partie (maximum 15 %) du matériel assimilé, contribution largement inférieure à la contribution en tant que matériel ingéré. Ceci souligne que le rôle de ces espèces dans la dégradation de la litière de P. oceanica est principalement mécanique (i.e. fragmentation des particules) et que la microflore associée aux feuilles mortes constitue vraisemblablement une source alimentaire importante. C’est probablement l’hétérogénéité de l’habitat et la diversité trophique des Idotéidés qui permettent leur coexistence au sein des mêmes biotopes. [less ▲]

The aim of this work was to study the ability of two different strains of the yeast Yarrowia lipolytica to grow on Olive Mill Wastewater (OMW) and their potential to produce high-value products such as lipases. Factors affecting cellular growth and OMW degradation were studied, such as nitrogen supplementation, cells concentration and surfactant addition. Both strains used were able to grow in an OMW with a COD of 19 g/L and total phenols concentration of around 800 mg/L. The strain W29 presented the highest potential for extracellular lipase production from OMW. Lipase productivity was improved by the medium supplementation with ammonium sulphate up to 6 g/L, leading to 80 % of COD degradation and 70 % of total phenols reduction. The surfactant Tween 80 enhanced cell growth and COD degradation, but had no significant effect on lipase productivity. The results evidenced that the conditions that favoured lipase production differ from the conditions that improve COD removal from OMW. [less ▲]

R-parity can be violated through either bilinear and/or trilinear terms in the superpotential. The decay properties of sneutrinos can be used to obtain information about the relative importance of these couplings provided sneutrinos are the lightest supersymmetric particles. We show that in some specific scenarios it is even possible to decide whether bilinear or trilinear terms give the dominant contribution to the neutrino mass matrix. [less ▲]

Colloque - Répondre à la question de la conciliation des intérêts économiques et sociaux dans les centres d’appels ne peut se faire sans prendre en considération l’extrême hétérogénéité du secteur et des entreprises qui le composent. Souvent dénoncé pour la dégradation des conditions d’emploi et de travail qu’il entraîne, ce secteur d’activité est pourtant loin de répondre à une seule et même logique dans la gestion de l’emploi. Des études de cas diversifiées selon deux axes, le niveau de valeur ajoutée des services offerts par le centre d’appels, et sa complexité organisationnelle, laissent émerger des logiques différentes, influencées par la position de l’entreprise étudiée sur ces deux axes. Elles montrent l’existence d’un lien entre la configuration prise par la relation d’affaires qui unit le centre d’appels à ses clients ou donneurs d’ordres, et la politique interne de gestion de l’emploi. Ce lien n’est pas sans effet sur l’extrême difficulté à concilier les intérêts des travailleurs avec ceux des clients, particulièrement lorsque ces derniers interviennent lourdement dans la gestion interne du centre d’appels, ou en conditionnent fortement le fonctionnement par des exigences contractuelles.

By oxymetry and electron paramagnetic resonance (EPR), we investigated the effects of repeated anoxia/re-oxygenation (A/R) periods on the respiration and production of free radicals by synoviocytes (rabbit HIG-82 cell line and primary equine synoviocytes) and equine articular chondrocytes. Three periods of 20 min anoxia followed by re-oxygenation were applied to 10(7)cells; O(2) consumption was measured before anoxia and after each re-oxygenation. After the last A/R, cellular free radical formation was investigated by EPR spectroscopy with spin trapping technique (n=3 for each cell line). Both types of synoviocytes showed a high O(2) consumption, which was slowered after anoxia. By EPR with the spin trap POBN, we proved a free radical formation. Results were similar for equine and rabbit synoviocytes. For chondrocytes, we observed a low O(2) consumption, unchanged by anoxia, and no free radical production. These observations suggest an oxidant activity of synoviocytes, potentially important for the onset of osteoarthritis. [less ▲]

It is well known that the optimal management of diabetes mellitus requires the use of various insulin formulations with complementary pharmacokinetics, in order to better mimic physiological (basal and postprandial) insulin secretion. Recent advances led to the production of insulin analogues thanks to the substitution of specific amino acids. Pharmacokinetics is improved, without affecting pharmacodynamics or increasing side-effects. These new insulin forms concern both so-called ultra-short insulin analogues and long-acting insulin analogues (basal insulin). Even if they are not able to dramatically lower glycated haemoglobin levels, these new insulins significantly reduce the risk of hypoglycaemia and offer some practical advantages that could improve the quality of life of diabetic patients.

Bone metabolism is very frequently disturbed in end stage renal failure hemodialyzed, with secondary hyperparathyroidism development but also serious potential cardiovascular consequences. New treatments will be available very soon in Europe such as new phosphate binders, vitamin D2 analogues or calcimimetics to fight against such medical diseases, with the hope of less risk for vascular complications. The real place of such new medical opportunities needs to be determined. Moreover, studies with morbidity and mortality end-points are waited before estimating the real importance of these new therapeutic tools. [less ▲]

Tiotropium is a long-acting anticholinergic bronchodilator, inhaled only once a day, which produces relaxation of airway smooth muscle through antagonism of acetylcholine at M3-muscarinic receptors. Its duration of action is at least 24 h with once daily administration of tiotropium. Several studies have shown its efficacy and its good tolerance in the treatment of patients who are suffering from moderate to very severe chronic obstructive pulmonary disease (COPD). Tiotropium improves spirometric measurements and quality of life, and reduces dyspnea and exacerbation rate in COPD patients. [less ▲]

Because of pelagic-larval dispersal, coral-reef fishes are distributed widely with minimal genetic differentiation between populations. Amphiprion akallopisos, a clownfish that uses sound production to defend its anemone territory, has a wide but disjunct distribution in the Indian Ocean. We compared sounds produced by these fishes from populations in Madagascar and Indonesia, a distance of 6500 km. Differentiation of agonistic calls into distinct types indicates a complexity not previously recorded in fishes' acoustic communication. Moreover, various acoustic parameters, including peak frequency, pulse duration, number of peaks per pulse, differed between the two populations. The geographic comparison is the first to demonstrate 'dialects' in a marine fish species, and these differences in sound parameters suggest genetic divergence between these two populations. These results highlight the possible approach for investigating the role of sounds in fish behaviour in reproductive divergence and speciation. [less ▲]

Arrow and dart poisons, considered as conventional natural sources for future drug discovery, have already provided numerous biologically active molecules used as drugs in therapeutic applications or in pharmacological research. Plants containing alkaloids or cardiotonic glycosides have generally been the main ingredients responsible for the efficacy of these poisons, although some animals, such as frogs, have also been employed. This paper, without being exhaustive, reports the greater strides made during the past 15 years in the understanding of the chemical nature and biological properties of arrow and dart poison constituents. Examples both of promising biological properties shown by these molecules and of crucial discoveries achieved by their use as pharmacological tools are given. Further studies of these toxic principles are likely to enable scientists to find new valuable lead compounds, useful in many fields of research, like oncology, inflammation and infectious diseases. 2005 Elsevier Ireland Ltd.

Annually laminated sediments can provide an absolute time scale (by varve counting) and a high-resolution palaeoclimate information (from varve thickness). Both types of information may be directly measured from sediment core surfaces. In this paper, we stress that varve counting and varve thickness measurements derived from fresh core surfaces could not systematically reveal the internal sedimentary structure, even if assisted by high resolution image analysis. We present an example of a homogeneous sediment core for which the varves were only observable after core impregnation and polishing steps. Because the impregnation methods are not yet standardized, the aim of this paper is to give an updated review of the methodology. In this review, we present the major critical points during impregnation steps. In particular, we focus on all of the post-treatment sediment disturbances that can alter the laminated micro-structure and, consequently, varve measurements. Finally, we propose a modified impregnation protocol, especially adapted for tracking varved intervals in long cores. (c) 2005 Elsevier B.V. All rights reserved. [less ▲]
