The Design Space (DS) is defined as the set of factors settings (input conditions) that provides results at least better than pre-defined acceptance limits. The proposed methodology aims at identifying a region in the space of factors that will likely provide satisfactory results during the future use of an analytical method or process in routine, through an optimization process. First, in a Bayesian framework, DS is derived from the joint predictive posterior distribution of the responses in a multivariate multiple regression problem using non-informative as well as informative prior distribution of the parameters. The case of DS in presence of highly correlated responses will be covered. Second, a multi-criteria decision is taken with respect to the pre-defined acceptance limits, aiming to identify the DS of any analytical methods or other processes. A strong link is made between acceptance limits and objective functions to optimize, using desirability functions and index. Examples based on high-performance liquid chromatography (HPLC) methods will be given, illustrating the applicability of the methodology with highly correlated and constrained responses. [less ▲]

Introduction : Depuis une vingtaine d’années, le développement des activités sportives s’accompagne d’une incidence accrue de diverses tendinopathies, souvent rebelles aux traitements conservateurs classiques (anti-inflammatoires non stéroïdiens, orthèses, kinésithérapie, infiltrations…). De nouvelles thérapeutiques, dont l’injection de concentrés plaquettaires (plasma riche en plaquettes ou PRP), sont actuellement en cours d’évaluation clinique. Objectifs : L’injection de PRP fait actuellement l’objet de recherche comme thérapeutique des tendinopathies chroniques. L’injection intra-tendineuse nécessite idéalement un volume minimal afin de diminuer la pression lors de l’injection et minimiser les douleurs, mais il doit également présenter une concentration plaquettaire élevée ; par ailleurs, la quantité de facteurs de croissance libérés pourrait être liée au système de préparation. Méthodes : Après avoir prélevés divers échantillons de sang veineux chez 5 patients, nous avons comparé 5 techniques de préparation du PRP : celle du Service d’Hématologie Biologique du CHU de Liège, le PRP Kit de Curasan®, les techniques Plateltex®, GPS®II et RegenLab®. Résultats : Les différentes techniques permettent d’obtenir des concentrations plaquettaires plus importantes que dans le sang avec des volumes variables (de 0,3 mL à 6 mL) et un nombre de globules rouges et globules blancs limité (sauf pour GPS® II). Le nombre de plaquettes/µL apparaît plus élevé avec la technique Plateltex® et obtient le plus petit volume à injecter. Les autres techniques permettent également d’obtenir de petits volumes sauf avec le GPS®II. Le nombre de plaquettes collectées dans le PRP apparaît donc plus élevé avec cette technique mais avec une concentration faible. Discussion – Conclusion : La technique décrite par Plateltex® permet de recueillir le PRP le plus concentré dans le volume le plus faible. [less ▲]

At high frequencies, the sound propagation can be approximated by the propagation of sound particles which are reflected and absorbed at the boundaries. This propagation follows then a transport process. In urban canyons, this transport process can be reduced to a diffusion process. The resultant model allows one to obtain the spatial distribution of the acoustical energy in a street in a few seconds using a classical finite elements program. This diffusion model has been previously validated in rectilinear streets for different geometrical and acoustical parameters. In this paper, more complex geometries such as varying cross-sections, bents and streets crossings are dealt with. As the diffusion model only models the reverberated sound field, diffraction effects on the direct sound field at streets corners are added. The obtained results are then compared to scale model experiments. [less ▲]

This paper presents an overview of the state of art of ship impact analysis on lock gates. First, the different kinds of analysis are presented, which are: empirical approach, analytical-rational approach, and finite element methods performed with quasi-static analysis or dynamic analysis. A discussion on the hypothesis and the calculus time required by each method is carried out with a view to clarify the state-of-practice for engineers. Then, a quasi-static analysis by finite elements modeling a ship impact is performed on the specific case of a new lock gate designed in Belgium for the “Seine-Escaut Est” project. The results suggest some design recommendations to provide a ductile behavior and so impact strength for the gate structure. [less ▲]

In this paper, an implementation of a model for room-acoustic predictions in COMSOL Multiphysics is presented. The model (called diffusion model) is based on the solving of diffusion equations instead of classical wave equations and allows simulating the sound propagation in complex geometries at high frequency. Instead of using COMSOL Multiplysics to solve directly the problem, a specific tool has been developed. It is composed of a user-friendly interface (I-Simpa) which manipulates all the physical data of the problem (geometries, acoustic properties and elements…) and generates an interoperability script to execute COMSOL Multiplysics via the generation of .m file scripts. Then, numerical results are processed by I-Simpa for the acoustic post-treatment and results display, like sound levels, reverberation times… [less ▲]

Introduction : Certaines tendinopathies (l’épicondylite, la tendinopathie rotulienne supérieure ou encore la tendinopathie d’Achille) demeurent rebelles malgré un traitement « classique » bien conduit : repos, orthèse, AINS, électrothérapie, kinésithérapie, infiltrations de corticoïdes, ondes de choc... Certains travaux, essentiellement in vitro, soulignent les potentialités réparatrices des plaquettes qui présentent la capacité d’accélérer la cicatrisation de différents tissus : os, muscles et tendons. Objectifs : Le but de notre étude préliminaire est d’objectiver l’effet « accélérateur » sur la réparation tendineuse suite à l’emploi d’injection de plasma enrichi en plaquettes (platelet-rich plasma ou PRP) car cette technique pourrait représenter une thérapeutique d’avenir en médecine physique et en traumatologie du sport. Méthodes : Nous avons sectionné et réalisé un défect de 5mm dans le tendon d’Achille de rats (N = 12). Quatre rats ont bénéficié d’une injection in loco de PRP et remis en liberté comme les autres dans leur cage. Trois rats (2 sans PRP et 1 avec PRP) sont euthanasiés à J5, J10, J20 et J30 et le tendon d’Achille en cours de régénération est disséqué et prélevé. Une étude biomécanique de traction jusqu’à rupture est réalisé à l’aide de « Cryo-jaw ». Résultats : L’analyse des résultats montre que la force développée pour obtenir la rupture tendineuse doit être plus importante pour les tendons ayant bénéficié d’une injection de PRP et ce dès J5. Discussion – Conclusion : Cette série préliminaire permet de montrer que les injections de PRP permettent une accélération de la cicatrisation tendineuse et une augmentation des valeurs de résistances à la traction. Une étude avec un plus grand nombre de sujets est en cours. [less ▲]

The aim of the TIMODAZ project is to investigate the effect of thermal changes on the excavation damaged zone (EDZ) around nuclear deep disposals in clay-based geological formations. In the framework of WP5.2 of this project, it is intended to develop constitutive models and numerical tools reproducing the thermo-hydro-mechanical (THM) evolution of the host rocks at real time and repository scale. Predictive THM modelling of on-going laboratory experiments has been realised by several partners of the project to compare different finite element codes and to provide a first insight into the THM responses of the tested materials. The experiment consists of a hollow cylinder of clayey material, which is subjected to THM loadings. The modelling of this experiment is realised with different constitutive laws (thermo-elasticity, elastic-perfectly plastic laws, hardening plasticity and/or thermo-plasticity). Results show that the choice of the THM model is a key issue for the prediction of the process implied in this modelling. For the current objective of this work, the assumption of isotropy was found to be fair enough. However, preliminary experimental results got in WP3 of the present project point out a certain mechanical anisotropy of the tested clay. Consequently, further development of constitutive laws considering mechanical anisotropy will probably be necessary in the future. [less ▲]

Impaired memory performance does not constitute the prominent deficit in frontotemporal dementia (FTD). Nevertheless, it has been suggested that some specific aspects of memory may be disrupted in FTD patients, in particular, the ability to consciously recollect the context in which information has been learned (Simons et al., 2002). The aims of the current study was to investigate the states of awareness accompanying recognition memory by asking participants to make Remember/Know/Guess judgments. Concretely, 12 FDT patients and 12 matched healthy participants studied 20 word pairs. During cued recall, each trial consisted of one word from a pair and participants had to try to recall the associated word. Finally, a 5-alternative forced-choice recognition task was given and participants had to say whether they chose a word because they recollected the study context (Remember), they knew they saw the word, without recalling anything else (Know) or they guessed (Guess). Results from the cued recall and recognition parts indicated that FTD recalled less word pairs than the controls, but had similar levels of recognition performance. Nevertheless, FTD patients gave less Remember responses than the controls, and tended to give more Guess responses. To conclude, episodic memory performance in FTD was characterised by impaired self-initiated memory retrieval processes. Although global recognition memory performance was preserved, FTD patients’ memories lacked of autonoetic consciousness and were mainly based on familiarity judgments and guessing. This pattern of results is similar to that found in patients with focal frontal lobe lesions (e.g., Wheeler et al., 1995; Wheeler & Stuss, 2003) and is consistent with the idea that the memory dysfunctions observed in FTD may stem from damage to the prefrontal cortex.

Neurodegeneration is a molecular process that occurs during several brain diseases (Parkinson, Alzheimer, Epilepsies). This process leads to the reorganization of synapses and neurons in the Central Nervous System. The search for early medication to reduce neurodegeneration is a major challenge in Neuroscience. To this aim, VALAPODYN, a European Commission-funded research network, develops functional genomics and proteomics related to the dynamics of molecular interaction networks (MIN). MIN modeling investigates protein-protein interactions and regulation networks. Using a mouse model of induced hippocampal cell loss associated with focal epilepsy, dynamic protein expression analyses were conducted at 10 successive time-points during the first 24h. Protein expression was analysed by mass spectrometry, using a “classical” gel-based method as a means of covering all modulated proteins at each considered time-points. Proteins were extracted from minutes amount of frozen hippocampal samples and subjected on two-dimensional difference in-gel electrophoresis (2D-DIGE). This analysis allows quantification of cyanine-labelled proteins. A total of 252 differentially regulated proteins spots were picked digested and identified using MALDI/TOF-TOF mass spectrometry. Overall the expressions of 127 different proteins were identified as reproducibly modulated over the time-range studied. Several proteins have multiple protein spots resulting from different isoforms. The functional annotation of these proteins shows that, among other mechanisms, most of them are involved in the response to stress, synapse remodelling, neuron development, and intracellular signal transduction.

The micro-PIV technique represents a development of the general particle image velocimetry technique to applications in fluid mechanics phenomena at a micrometric scale. It takes advantage from the very small depth of field of long distance objectives with high magnification to carry out accurate measurements in the focusing plane. The typical configuration consists of a microscope coupled to a pulsated laser and a double exposure PIV camera. The flow is seeded using sub-micrometric fluorescent particles. The laser light is directed on the investigated flow through the epifluorescent microscope objective. The light re-emitted by the fluorescent particles is detected by the PIV camera equipped of an optical filter to select only the fluorescence wavelength. The micro-PIV technique presents a large interest in the validation of numerical codes developed in different micro-fluidic framework such as biological flows and in industrial application as the ink-jet print-head. To investigate the micro-PIV measurements capabilities for fast moving and deforming droplets, measurement of the flow inside a jet ejected by a piezo-driven capillary up to the droplet formation by Rayleigh instability are studied in combination with PTV in order to distinguish the main liquid movement from the bulk one. Liquids differing from each other for their viscosity and their surface tension as well as piezo-element frequency in the 1 to 8 KHz range are investigated. The flow rate of the jet is adjusted by means of a pushing syringe system. Low concentration of 0.86 microns fluorescent particles is employed as seeding in order to have good signal to noise ratios. The ensemble averaging method is used to increase the height of the correlation peaks. Stroboscopic method is used to achieve several couples of frames taken in the same conditions thanks to high repeatability of piezo-driven instabilities. Moreover changing the delay of stroboscopy all the droplet formation phases can be analyzed in detail. In the experimental configuration, optical aberrations play a role since they affect the position and shape of the particle images and as a consequence the velocity field. The two main optical aberration experienced are astigmatism and measurement plane deformation. Astigmatism cannot be avoided in the experimental configuration, as it is clearly observed on droplet images were particles above and bellow the focalisation plane appear as perpendicular lines (Fig 1a). Nevertheless cross correlation method is not sensitive on particle image shape. As the measurement plane defined by the focal plane of the microscope is located inside a curved transparent object, it deformed as it was passing through a lens. The deformation of the objective plane affects the measurements as a function of the optical configuration, droplet curvature and relative refractive index. However, in the studied configuration, deformed plane differs only from the straight one of about 8 µm. The micro-PIV method is therefore suited to measure the instantaneous vector field inside droplets through cross-correlation methods (Fig 1b). The internal flow recirculation is observed. Measurements can be also performed in different planes inside the droplet depending on focalisation plane. [less ▲]

The title of Robert Drewe’s latest novel, Grace (2005), shares with J. M. Coetzee’s antonymous Disgrace (1999) a polysemous quality which derives from both works’ attempt to capture the ethical stance of a society in a way which has personal and political ramifications at the same time. The Australian text shows some concern with the predicament of a boatload of asylum seekers from Indonesia, who later escape from their detention centre in the Kimberleys; but Drewe’s progressive denunciation of Australia’s treatment of refugees is potentially compromised by the Australian anxiety over territorial integrity which provides an unshakeable context for this kind of thematic development. More generally, my paper will explore the ambiguities attending a discursive move which seeks to absorb race into larger categories of political meaning, and the related difficulty of achieving the ‘grace’ of complete freedom from colonialist parameters in an Australian culture where some suspense over territory continues to brood.

Milk fatty acid (FA) profile is far from the optimal fat composition in regards to human health. Different natural sources of variation such as feeding or genetics could be used to modify the contents of unsaturated fatty acids. The impact of feeding is well described; however, genetics effects on the milk FA composition are not well studied. Increasing the unsaturated fatty acids contents of bovine milk could have the potential to raise the nutritive and therapeutic values of dairy products. The stearoyl Coenzyme-A desaturase 9 (delta-9) gene was identified as a potential functional candidate gene affecting milk fat composition in dairy cattle. The objective of this research was to study the genetic variability on this enzyme activity across lactations. A total of 199,977 test-day records were obtained from 29,603 Holstein cows in first lactation, 154,267 records from 23,453 Holstein cows in second lactation, and 173,244 records from 75,887 Holstein cows in third and later lactations. The used model was a multiple-trait random regressions test-day model. Fixed effects were: herd x date of test, and class of age. Random effects were: herd x year of calving, permanent environmental, additive genetic, and residual effects. The studied traits were milk yield, protein content, percentage of fat, monounsaturated fatty acids estimated by mid-infrared spectrometry, and the ratios reflecting the delta-9 activity. Obtained heritability estimates of delta-9 as well as the genetic and phenotypic correlations varied across lactations. These results suggest potential improvements of milk fat composition based on delta-9 activity using animal selection and appropriate management practices. [less ▲]

Sustainability of breeding programs under the flow of exchange among various environments are conditioned by the ability of genotypes to adjust sufficiently their phenotypes in response to changes in their new bio-physical conditions, and also by the capabilities of farmers to balance between environmental, ethical, social. and economic aspects. The objective of this paper was to quantify the effectiveness of genetic responses from indirect selection in high- and low- to medium- input systems using Luxembourg and Tunisian Hoisteins. The magnitude of genotype-by-environment interaction (GxE) for production traits was firstly investigated based on the country border delimitation as environmental character state. Secondly, three herd management levels reflecting feeding and management intensity were identified in each country and GxE was investigated within and across country environments. Significant GxE was detected for milk yield and persistency with large differences in genetic and permanent environmental variances between the 2 countries. Genetic correlations for 305-d milk yield and persistency between Luxembourg and Tunisia were 0.60 and 0.36. Low rank correlations obtained between estimated breeding values of common sires translated a significant re-ranking between the 2 countries. Within-country environments analysis show that the magnitude of GxE varied from only scaling effects resulting from heterogeneous variances in high-input systems to considerable re-ranking of common sires under limited feeding resources, low management care, and stressful conditions in low-input systems. Overall, this study shows that substantial differences exist between Hoisteins in terms of their sensitivity to production environ ment suspecting the sustainability of the dairying system. In high-input systems, GxE effects are expected to be easily managed but harmful effects of intensive dairy systems should be considered. Selection of breeds under less intensive production systems respecting the ruminant's specificities should be encouraged. In law-input systems, selection for adaptive traits under their specifie conditions and improvement of management conditions and husbandry practices are needed. [less ▲]

These objectives in dairy cattle have been changing in the last forty years passing from simple yield only potentially associated with type, towards more complex ones including also functional traits as fertility and longevity. Milk composition has been selected too in most countries, however focussing only on major components, fat and protein. During the last years interest in milk quality traits, especially nutritionally quality has been increasing. Implementing breeding for additional traits first requires that animals can be evaluated for them because data is available and they are heritable enough. The objective of our research was to develop the needed steps to implement animal breeding for improved nutritional quality. Until recently data for fatty acid (FA) composition could not be obtained easily. However calibration equations for mid-infrared (MIR) spectrometry data generated in routine milk analysis done during milk recording were developed. They are used in routine in Belgium (Walloon Region) and Luxembourg and generate MIR data used to predict FA for up to 100.000 cows for every test date, therefore up to a maximum of 1 million test-day records. Multivariate test-day models were developed that allow estimating genetic parameters and ultimately breeding values as soon as enough data is available. Daily heritabilities estimated ranged between 0.1 and 0.4 showing that sufficient genetic differences exist. Because of the lack of historical data correlated traits as milk yield, fat and protein content will be analyse together with FA. For the future research on correlations between FA and other economically important traits will be done. Results are needed to integrate FA in the selection objectives. Because of the relative lack of historical data there is a high interest to research using genomic information to provide combined breeding values. [less ▲]

As most of production pathologies in dairy farming, mastitis is characterized by a multifactorial aetiology. Its diagnosis and treatment requires a good knowledge of its determinant and predisposing factors. The comparative epidemiology of 349 walloon farms registered to individual milk analysis programs led to highlight the practices used in farms whose last 3 months' herd somatic cell count was above 400.000 cells/ml. We identified the following risk indicators relative to 1) herd demography : age, composition, herd production average, percentage of high cell counts animals 2) the animal housing : use of straw as bedding stall for all classes of animals and lack of a calving pen 3) the milking machine : milking cups cleaning 4) the dairy practices : lack of washing cloth towels between 2 milkings, occasional foremilk check, stripping, lack of post-dip and 5) animal nutrition : mould on beet pulp silos and composition of the main concentrate. This descriptive and univariate analysis confirmed the risky situation of a large majority of dairy farms regarding the recommendations of good dairy practices guides. [less ▲]

Due to an increasing need for polymers with well-defined architecture (diblock-, graft-, star-shaped copolymers), molecular weight and/or functional end-groups, the use of controlled radical polymerization (CRP) in scCO2 has started to gain attention. Among all the controlled processes, Atom Transfer Radical Polymerization has emerged as a robust tool for the preparation of polymers with well-defined molecular weight, architecture and chain-end functionality. In a very recent paper, we reported the first efficient dispersion ATRP of methyl methacrylate (MMA) in scCO2 using a fluorinated polymeric ligand that had a dual role, i.e., the complexation of the copper salt and the stabilization of PMMA growing particles. In this contribution, we extended this new system to the dispersion ATRP of styrene2, to the synthesis of diblock copolymers beads2 or to the preparation of PMMA particles by AGET ATRP. Because both ATRP and alkyne-azide Huisgen’s 1,3-dipolar cycloaddition relies on the use of a Cu(I) catalyst, synthesis of pyrene end-functionalized polymers by simultaneous dispersion ATRP and click reaction was also investigated in supercritical carbon dioxide. Finally, the immobilization of these new macroligands onto an inorganic support leads to the formation of pseudo-homogeneous catalyst that were successfully used to prepare CO2-soluble perfluorinated methacrylate and depending on the molecular weight and TEDETA composition of the macroligand, results obtained by supported ATRP without addition of Cu(II) as deactivator are identical to those obtained by homogeneous ATRP.

Controlled dispersion Nitroxide Mediated Polymerization (NMP) of methyl methacrylate (MMA) was successfully carried out for the first time in supercritical carbon dioxide (scCO2) in the presence of CO2-philic perfluorinated surfactant that was generated “in situ”. The control of the MMA polymerization relies on the strategy developed by Charleux et al. that consists of using a SG1-based alkoxyamine, i.e. the block-builder, in the presence of small amount of styrene. In a first step, CO2 soluble polyheptadecafluorodecylacrylate was prepared in scCO2 using block-builder as an alkoxyamine. In a second step, nitroxide SG1 mediated dispersion polymerization of MMA was conducted at 70°C and 300 bar in the presence of 5 w% of SG1 terminated surfactant compared to the monomer. Different monomer to alkoxyamine molar ratios were investigated in order to target different molecular weights. In each case, the monomer conversion was high (>90 %), the experimental molecular weight was in good agreement with the theoretical value and the polydispersity was narrow (Mw/Mn ~1.2). Moreover, after depressurisation of the cell, PMMA was collected as a free flowing powder consisting of small sized microspheres. [less ▲]

Cobalt-Mediated Radical Polymerization (CMRP) imparts a high level of control on the polymerization of acrylic and vinylic esters, acrylic acid and acrylonitrile. However, each class of monomers appears to be controlled by one class of cobalt complexes. For example, the polymerization of acrylates and acrylic acid is mediated by cobalt porphyrin complexes while vinyl acetate (VAc) and acrylonitrile are efficiently controlled by bis(acetylacetonato)cobalt(II) (Co(acac)2). Therefore, a challenging issue in CMRP remains to broaden the range of monomers that can be controlled by the same cobalt complex. Recently, the controlled random copolymerization of butyl acrylate (BuA) with VAc was performed using the conventional V-70/Co(acac)2 CMRP system, but the homopolymerization of BuA remained uncontrolled. In this work, we used a new alkylcobalt(III) adduct to initiate and control the copolymerization of BuA with VAc. This achievement resulted in a significant improvement over the V-70/Co(acac)2 pair regarding the molecular weight control and the polydispersity indexes. Moreover, for the first time, the alkylcobalt(III) adduct was also efficient in controlling the homopolymerization of BuA and yielded low polydispersity PBuA even in the absence of VAc. These results indicate that Co(acac)2 is a versatile mediator for the CMRP of both unconjugated vinyl monomers (VAc, N-vinylpyrrolidone) and conjugated monomers such as acrylates. It gives access to copolymers that cannot be prepared by other controlled radical polymerization techniques. [less ▲]

Macromolecular engineering is one of the most powerful tool to synthesise many polymers of various architectures and with tailored properties. This contribution aims at reporting on a novel strategy for the macromolecular engineering of poly-ε-caprolactone (PCL) which is based on the use of a dual monomer / initiator compound, α-chloro-ε-caprolactone (αClεCL). Indeed, αClεCL is not only polymerizable by ring opening initiated by metal alkoxides, but it is also an initiator for the atom transfer radical polymerization (ATRP) of vinyl monomers, so leading easily to the synthesis of macromonomers. Polystyrene macromonomer has been prepared by this method and successfully copolymerized with ε-caprolactone (εCL) with formation of the corresponding grafted PCL. αClεCL is also a precursor of copolyesters with εCL that bear pendant chlorides. These (co)polyesters have been used as macroinitiators for the ATRP of methyl methacrylate in order to synthesise the corresponding graft copolymer. On the other hand, the pendant chlorides of poly(αClεCL-co-εCL) copolyesters were easily converted into azide with formation of the corresponding azide bearing copolyester. This copolyester was then reacted with an alkyne bearing an ATRP initiator by “Click chemistry”. The conversion of chlorides into more efficient ATRP initiators led to the improvement of the initiation efficiency of the macroinitiator. [less ▲]

Nowadays, progresses in medicine, biotechnology, microelectronic and many other fields are more and more sustained by the development of novel polymer materials with constantly improved properties and well-defined molecular parameters. In this context, we designed an innovative and very promising tool for macromolecular engineering. This technique, called Isoprene-Assisted Radical Coupling (I-ARC), allows to couple quantitatively polymer chains preformed by Cobalt-Mediated Radical Polymerization (CMRP), an efficient controlled radical polymerization system for vinyl acetate (VAc) and acrylonitrile (AN). Typically, addition of isoprene to well-defined polymers prepared by CMRP invariably leads to the quantitative coupling reaction of the chains, as assessed by the perfect doubling of the molar mass of the polymer. Importantly, the I-ARC reaction is not limited to macromolecules with low molar masses and homopolymers, contrary to the previously reported radical chains coupling methods. Indeed, when applied to diblock copolymers, I-ARC constitutes a straightforward approach for the synthesis of telechelic symmetrical ABA triblock copolymers, as illustrated by the preparation of poly(vinyl acetate)-b-poly(acrylonitrile)-b-poly(vinyl acetate) triblock copolymers and their derivatives.

Controlled Radical Polymerization techniques have been developed to obtain well-defined architectures and to control polymer parameters. Among these systems is Cobalt-Mediated Radical Polymerization (CMRP), which is based on the reversible deactivation of the growing radical chains with a cobalt complex, the cobalt (II) bis(acetylacetonate). The interest of this system is not only due to its ability to control the polymerization of very reactive monomers such as vinyl acetate (VAc) and N-vinylpyrrolidone (NVP), but also its peculiar mechanism which exhibits two pathways depending on the polymerization conditions; a reversible termination process and a degenerative chain transfer mechanism. Furthermore, it has been showed that the Co-C bond strength and thus the polymerization are strongly influenced by the use of some additives, such as water, dimethylformamide, dimethylsulfoxide and pyridine, which coordinate the cobalt free site. In this presentation we report the use of a preformed alkyl-cobalt(III) adduct as initiator for the polymerization of various vinyl monomers of different reactivity (VAc, acrylonitrile,…) and on the effect of several ligands on their polymerization control. The preparation of novel block copolymers by CMRP will finally be presented. As a conclusion, cobalt-coordination appears today as a unique opportunity to adjust the Co-C bond strength and to push back the bounds of possibilities in terms of macromolecular engineering assisted by CMRP.

Limb profiles of the CO Cameron and CO2+ doublet airglow have been observed over different conditions (latitude, season, SZA, F10.7). They have been individually modelled using currently accepted cross sections, and outputs from the MTGCM. They have been shown to co-vary, with a ICO/ICO2+ ratio of about 4.7, less than the modelled ratio.The peak brightness varies linearly with the F10.7 solar flux proxy, in a way compatible with the Mariner 6 and 7 observations. The intensity of both emissions is overestimated by the model (but large uncertainties exist in excitation cross sections). An increase of the altitude of both emissions has been observed during the 2005 summer season. It is a consequence of the dust load, followed by an increased thermospheric CO2 density observed with SPICAV during the same period. This density enhancement is partly predicted by GCM models.

The present article aims to provide a synthetical analysis of the various methods used to measure the non-market dimension of a product. In a first stage, we define the various notions linked to the dimensions of the production of a "merit good": direct and indirect impacts, externalities, collective impacts, etc. We then envisage the way in which these various dimensions are generally measured in economic literature, and we highlight the advantages and drawbacks of the various methods. We attempt to demonstrate why the method based on the economic value of a non-market production, despite its advantages and its success, raises many methodological, but also, more fundamentally, conceptual questions, which jeopardise the reliability of the estimations produced. As far as the production of social enterprises is concerned, the article will thus make a case for a more classical approach, mainly based on the method of indicators. [less ▲]

Nepal is localized in the central part of the Himalayan arc. In uplift since the Cenozoic time, the Himalaya is traditionally divided into six lithotectonic zones extending in parallel belts. From north to south there are respectively: (1) the Trans-Himalayan batholith; (2) the Indus-Tsangpo suture zone; (3) the Tethyan (Tibetan) Himalaya; (4) the Higher (Greater) Himalaya; (5) the Lesser Himalaya; and (6) the Sub-Himalaya. This PhD thesis is focused on the Tethyan sedimentary rocks exposed in the Nepal Tethyan Himalaya belt and in the thrusting nappes belonging to the Lesser Himalaya. These nappes contain unmetamorphosed sedimentary rocks which might belong to the Tethyan sedimentary succession. The Tethyan Himalaya has preserved highly fossiliferous marine rocks deposited on the shelf and slope of the Indian continental margin from Late Proterozoic-Cambrian through early Eocene times. The main objective of this PhD thesis is to build a first sedimentological canvas for the Lower Paleozoic and Devonian carbonated rocks of Nepal which could be compared with the Belgian facies. This long distance comparison between the Belgian and the Nepalese basins will allow to have a better understanding of the phenomena that run the global carbonate sedimentation. The methods that will be used to achieve this work are: (1) bed by bed sampling; (2) petrographic analysis and facies modelling; (3) magnetic susceptibility analysis for correlations and eustatism and (4) paleontological datation. A first sedimentological campaign took place during the months of March and April 2009. It allowed to study three sections around Katmandu valley and two sections in the Annapurna range (Manang area). The sections studied around Katmandu (Pulchauki and Chandragiri Hill) belonged to the Formation of Chandragiri (Ordovician) and Godavari (Devonian) which are mainly constituted by carbonate rocks. The sections described in Manang area are mainly made-up by the terrigeneous rocks of the Dark Band, Tilicho Pass and Tilicho Lake Formation (Silurian to Lower Carboniferous). The diversity of facies observed in these five sections will be exposed. [less ▲]

The Future of Belgian Federalism is definitely a hot topic in Belgian politics but also in citizens’ daily life. Indeed, citizens do talk about it and wonder – and sometimes try to predict – how the future of Belgium will be. Yet, we only know their attitudes on this important topic through surveys either undertaken by the media or by social scientists. Thus far, no endeavour has been done to study thoroughly and qualitatively citizens’ preferences for the future of their country. In this paper, I propose to offer a first attempt of such an analysis relying on data collected in two small citizens’ panels about the future of Belgian federalism. These two deliberative events were held in Liege (French-speaking Belgium) in September 2007 and in Antwerp (Dutch-speaking Belgium) in October 2008 and gathered respectively 64 and 23 citizens from a variety of backgrounds. During one day, the participants talked about the future of Belgian federalism with fellow citizens in focus groups as well as with politicians and experts; in addition, they answered a pre- and a post-questionnaire. Following Max Weber’s advice to construct ideal type as a way to apprehend the reality and to foster comparisons, types of citizens are constructed on the basis of the data collected in Liège and in Antwerp. While four types of French-speaking are drawn from the former – the unitarist, the unionist, the federalist, and the regionalist –, five emerge from the latter – the unitarist, the unionist, the federalist, the regionalist, and the separatist/independentist. These different types are defined in terms of the citizens’ perceptions and preferences as well as the congruence that followed the learning and deliberative process that occurred throughout the panel. Above all, the types can be compared within the panel and between the panels. In this fashion the future of Belgian federalism can be explored through the eyes of the citizens. [less ▲]

Alcelaphine herpesvirus 1 (AlHV 1), carried by wildebeest asymptomatically, causes malignant catarrhal fever (WD MCF) when cross species transmitted to a variety of susceptible species of the Artiodactyla order. Experimentally, WD-MCF can be induced in rabbits. The lesions observed are very similar to those described in natural host species. Here, we used the rabbit model and in vivo 5-Bromo-2’-Deoxyuridine (BrdU) incorporation to study WD-MCF pathogenesis. The results obtained can be summarized as follows. (i) AlHV-1 infection induces CD8+ T cell proliferation detectable as early as 15 days post-inoculation. (ii) While the viral load in peripheral blood mononuclear cells remains below the detection level during most of the incubation period, it increases drastically few days before death. At that time, at least 10% of CD8+ cells carry the viral genome; while CD11b+, IgM+ and CD4+ cells do not. (iii) RT-PCR analyses of mononuclear cells isolated from the spleen and the popliteal lymph node of infected rabbits revealed no expression of ORF25 and ORF9, low or no expression of ORF50, and high or no expression of ORF73. Based on these data, we propose a new model for the pathogenesis of WD-MCF. This model relies on proliferation of infected CD8+ cells supporting a predominantly latent infection. [less ▲]

The paper considers social-demographic variables, such as the family and the school profile of the group of pupils ( school years 7, 8 and 9 in the ISRD- Belgium database) who are the most violent in our sample. We will then compare them with the less violent offenders. Taking a gender perspective, we will examine the dynamic and significant factors related to both levels of violence in each gender group in order to analyze similarities and differences. For example, previous studies and analyses have shown that seriously violent behaviour is significantly related to early family victimization of girls, a hypothesis that will also be examined.
