The administration of 6g per day of temocillin by continuous infusion in critically patients with severe nosocomial pneumonia allows a penetration ratio, measured by the ELF/plasma ratio of AUCs, of 0.14 and 0.57 and a mean (± SE) ELF concentration , in mg/L, of 9.8 ± 1.3 and 9.8 ± 1.6 for total and free drug, respectively. Standard error of AUCs should be calculated by the Bootstrap method and Monte Carlo simulations should be performed for subsequent PK/PD analysis. [less ▲]

Purchased in 1905 by G. Bénédite from the Antiquity market, the unprovenanced limestone bust of Akhenaten now kept in the Louvre Museum (under the inventory number E 11076) is world-famous but, in the end, rather poorly studied. In the context of an international research project entitled RetroColor 3D (funded by the Région Nouvelle Aquitaine, France, and the University of Bordeaux Montaigne, at Archeovision - UMS 3657 of the CNRS), this exceptional piece of sculpture was investigated anew with the help of 3D reconstruction as a methodological tool. Reporting on this transdisciplinary analysis, the paper will explain how this led to a better understanding of the bust’s original function in the creation of royal portraiture during the so-called Amarna period.

Durant le Paléolithique moyen, l’alternance entre les périodes glaciaire et interglaciaire a rendu le peuplement de la France septentrionale discontinu. Cette région bénéficie d’un bon cadre chronostratigraphique permettant l’étude des peuplements néandertaliens. Cependant certains aspects de leurs comportements restent encore mal caractérisés, particulièrement la fonction des sites reste souvent à préciser. L’étude de l’organisation spatiale intrasite apporte des éléments de réponse à ces questions. La fouille d’un site du Paléolithique moyen ne met pas directement en évidence l’organisation spatiale des lieux de vie, une modélisation est nécessaire pour la déceler. Nous avons donc débuté la construction d’un protocole d’analyse spatiale basé sur un Système d’Information Géographique et appuyé sur les sites de Caours. Ce site possède un rôle majeur de par sa superficie et l’excellente préservation des restes fauniques. Nous montrons ici l’existence d’une organisation spatiale sous forme de zones de concentration de vestiges en corrélant plusieurs méthodes – parmi lesquelles le K-mean Clustering et la Kernel Density Estimation. Nous préciserons ensuite la fonction de ces zones au sein d’un espace de vie et leur interaction entre elles au travers de la distribution spatiale des différents vestiges fauniques ou lithiques.

Animal breeding programs are designed to genetically improve livestock populations over many generations to enhance farm sustainability and competitiveness. Genetic improvement is achieved by selecting genetically superior animals, based on estimated breeding values, to be the parents of the next generation. These estimated breeding values are calculated by solving mixed model equations characterizing appropriate statistical genetic evaluation models. To guarantee effective genetic selection, genetic evaluation models must be tailored to the specific characteristics of the traits and population under evaluation. This PhD thesis focused on the development of genetic evaluation models suitable for categorical maternally influenced traits and for multi-breed populations. Appropriate genetic animal models were developed and assessed: (1) for two categorical maternally influenced traits based on calving ease scores from Walloon Holstein dairy cattle and on lamb survival data from a New Zealand sheep population; (2) for two multi-breed populations based on milk yield records of New Zealand purebred and crossbred dairy cattle, and on purebred and crossbred calving ease scores from Walloon Belgian Blue and Holstein cattle. Results showed that (1) fitting maternal effects was required to avoid biasing the estimated breeding values, and there was no clear advantage in using non-linear mixed models instead of linear mixed models for the genetic analysis of the two categorical maternal traits studied; (2) breed-dependent breeding values could be estimated using the proposed multi-breed models, and that combining purebred and crossbred data had a positive influence on the accuracy of the breeding values of purebred animals. Finally, part of the research presented in this thesis contributed to the development of the genetic evaluation systems currently used in Walloon Region of Belgium and in New Zealand. [less ▲]

Résumé de la thèse Le passage de l’Union Économique et Monétaire Ouest-Africaine (UEMOA) à une union douanière en janvier 2000 témoigne de la volonté des pays membres à promouvoir et à intensifier les échanges commerciaux au sein de la zone. Plus de 15 ans après la création de ce vaste marché, les chiffres du commerce intra-communautaire ne sont guère encourageants. En effet, le ratio d’échanges intra-UEMOA stagne autour de 12%, nettement en dessous de ses échanges avec ses partenaires de l’UE et des 7 autres pays de la CEDEAO. La présente thèse a d’abord investigué le poids des barrières dans les échanges intra-UEMOA relativement à celles dans les échanges avec l’Europe et les autres pays de la CEDEAO. Les résultats montrent l’existence de plus de barrières dans les échanges avec l’UE et la CEDEAO que dans les échanges intra-UEMOA. Mieux, la faiblesse des échanges intra-communautaires doit être résorbée moins par la réduction des barrières dans les échanges mutuels que l’amélioration des facteurs d’offre et de demande. Ensuite, nous avons montré que la faiblesse des échanges intra-UEMOA est liée à leur mauvaise structure. En effet, les résultats montrent que les flux croisés de biens similaires entre pays de l’UEMOA sont faibles et leur augmentation permettrait non seulement de stimuler les échanges intra-communautaires, mais également de créer un effet multiplicateur du commerce sur la croissance. Enfin, après avoir analysé la dynamique de la croissance, du commerce et des investissements directs étrangers dans l’UEMOA, nous montrons que s’il existe une dynamique positive de long terme entre la croissance et le commerce, les IDE sont par contre défavorables à la croissance de long terme. Les recommandations vont dans le sens d’orienter davantage les IDE vers les secteurs de transformations capables de générer plus de productivité à long terme. [less ▲]

Access to well-defined polymers made of the so-called ‘Less Activated Monomers’ (LAMs) via controlled radical polymerization has long been a challenge due to the lack of radical stabilizing group on the double bond of these monomers. This Feature Article summarizes substantial progress in the organometallic-mediated radical polymerization (OMRP) of this important class of monomers including vinyl esters, olefins, vinyl chloride, vinyl amides, or ionic-liquid vinyl monomers. It aims to provide a clear and comprehensive account of the fundamentals and challenges in the OMRP of LAMs as well as an overview of the resulting macromolecular engineering opportunities. The input of photochemistry, environmentally friendly solvents or flow reactors in OMRP is also presented. Finally, it emphasizes how some well-defined LAMs-based materials contributed to the development of specific applications notably in the fields of biomedicine or energy. [less ▲]

Objective: in this research, we studied changings and modulations of alexithymia [defined by Difficulties in Identifying Feelings (DIF); in Discussing Feelings (DDF) and by an Externally-Oriented Thinking (EOT)]. The purpose was to investigate if Day Psychiatric Hospitalization (DPH) could promote significant improvements on difficulties linked to alexithymia in a population of mood disorders patients (N = 73). Methods & results: a first study showed significant reductions of alexithymia scores. Considered as a personality trait, alexithymia’s changings lead us to promote the relative stability hypothesis, by displaying that moderate to high correlational levels were achieved. A second study revealed the variables impacting significantly on alexithymia. The selected variables were: demographic (i.e. gender; age; number of days of treatment); MMPI-2 variables; and perceived social support (assessed with the MSPSS scale). We found notably a positive effect of perceived social support (PSS) that reduced difficulties associated to alexithymia and other variables that increased alexithymia levels (e.g. antisocial practices, negative attitude to treatment). Conclusion: positive effects of PSS are well known and two main hypotheses were already proposed to explain its effect: PSS acting directly or as a buffer on stressful events. In conclusion, at the one hand, we showed that it is possible to significantly decrease at a certain level a phenomenon such as alexithymia. At the other hand, we enlightened significant modulators of alexithymia that might help therapists to promote or avoid specific aspects for patients involved in a recovery process. [less ▲]

This paper is a comprehensive analytical study of the murals belonging to an ancient Roman house through the characterization of materials. The project focuses on the wall paintings of the Domus dei Bucrani - a house of the end of the Republican era discovered on the site of the Schola del Traiano in Ostia. This domus has undergone several phases of development in the 1st century BC before being destroyed around 20 BC. A new house was immediately rebuilt after a major change from the ground, which allowed exceptional preservation of the decoration system. The results complement our knowledge of Roman painting techniques during the 1st century BC and also provide a comprehensive multidisciplinary approach to the problem of conservation of wall paintings. These two related objectives have been studied using non-destructive testing methods (MA-XRF, FTIR and Raman spectroscopy). The analyses have been performed in situ using our mobile systems. The different set-ups had to be modified in order to be able to work on horizontal surfaces, specially our XRF scanner. The study of the pictorial layers address various issues in the field of archaeology: what technique has been implemented? Does the same technique was used in both phases of the development of the domus? Do they correspond to the techniques described by ancient writers? These responses are compared to those observed in other sets of murals dating from the 1st century BC. [less ▲]

Between 30.000 and 28.000 BP, the material culture of European hunter-gatherers societies is affected by a series of modifications leading to the development of new technical and symbolic traits commonly labelled as “Gravettian”. The Gravettian period display a very broad distribution of these traits, whether in terms of geography or in terms of chronology. Their adoption, and the consecutive disappearance of those prevailing during the Aurignacian, is still largely debated. Several hypotheses are considered, going from a diffusion process coming from Central Europe, to a simultaneous development of the Gravettian in various areas across Europe. To address such question, regions like Central Europe and South-West France play a major role because of numerous sites offering reliable data. North-western Europe, on the contrary, is characterized by the scarcity of well-documented sites, a situation that also characterise the EUP in general in this region. Stratigraphic sequences, especially those of Belgium, are also problematic because of a long history of research starting in the 19th century. However, a limited number of open-air sites dated to the early phase of the Gravettian period, reunite the conditions for an extensive study of Early Gravettian technical behaviours: Maisières-Canal (Province of Hainaut, Belgium), Ormesson – Les Bossats (Seine-et-Marne, France) and, to a lesser extent, Station de l’Hermitage (Province of Liège, Belgium). The study of the lithic industries recovered at these sites, suggest that the appearance of the Gravettian was a progressive process in North-western Europe, taking place between 28.000 and 26.000 BP, and involving the development of at least one specific technical tradition. This tradition diverges from the usual Early Gravettian industries on technological, typological and functional grounds. Therefore, we intend to show that, despite the overall poverty of the data regarding the EUP in North-West Europe, this territory can nonetheless participate significantly to the reflections on the developmental process of the Gravettian.
