The Aquapôle of the University of Liège has been involved in environment modelling for more than 20 years. Its R&D unit focused on the domain of surface water, targeted to water quality. One of its environmental models, called PEGASE (Planification Et Gestion de l’ASsainissement des Eaux), French acronym for ―Planning and management of water purification‖ is devoted to the characterization of the environmental state of surface water, at the scale of a whole watershed, basin and district. The software has been used operationally in several countries like France and Benelux, but several calculations have also been performed at international level for the international commissions in charge of the Scheldt and the Meuse. PEGASE model requires as input, at least data like digital terrain models, water flow, water level and other hydrodynamic measurements in some geo-localized points, diffuse loads properties, ecological model data (to characterize bacteria, phytoplankton, zooplankton, macrophytes, shells, etc…), chemical discharges (from industry and cities) and treatment plant effect. The output of the software consists in tables, graphs and maps, showing the state of various calculated parameters of quality (DO, BOD, COD, N, P, Chla,… + indices) either at a specified time, along the river, or the temporal evolution at a given point. It provides printed maps or animations of the evolution of the results on the basin. The software is able to simulate non stationary scenarios from a local scale, up to a global scale i.e. a few km² to hundreds of thousands km² and handles the entire river tree (hundreds to thousands of water bodies). Some results of the model are already used to populate the SoE-Wise databases. On another hand, the model is a tool to validate and check consistency of SoE-Wise data at district (and thus international) level. The flexibility of the model enables to choose the time (daily to yearly periods) and spatial (watershed, water body, district, region, country …) scales of the expected results. PEGASE is also a full-scale operational tool for WFD implementation and WISE databases. This means that our partners handle a software (also known as the model) directly usable – and of direct help – in the implementation of the WFD and other water related directives. The model allows the member states to compare efficiently the collected international WISE data and populate database with relevant model results. We propose not only to read the data directly from the database to avoid manipulation mistakes, but also we propose to generate output data in a format directly exploitable by WISE databases administration.

This paper presents a way to minimize cost in shipbuilding industry by using the results of a data mining analysis aiming to improve the cost knowledge of the additional operations caused by welding distortions. This statistical analysis had the scope to establish assessment formulas of the supplementary workloads in function of scantlings and welding distortions. Those formulas can be useful to evaluate the profitability of new welding devices and can improve the research in the following domains: production simulation, cost assessment of ship hull, structure optimization, design for production, etc. [less ▲]

Introduction With the support of the Belgian Health Care Knowledge Centre (KCE), a systematic review of the EBM literature concerning the management of low back pain (LBP) patients in the occupational health (OH) context has been undertaken in order to issue good practices recommendations for occupational physicians (OP). Methods The guidelines development proceeded in three steps. First, an electronic search was performed to retrieve relevant guidelines and systematic reviews (SR) from 8 international databases. The identified guidelines were appraised using the AGREE method, while SR’s were appraised using the Cochrane Collaboration grid: 7 guidelines and 27 SR’s were selected. A draft of the intended Belgian guidelines was then validated by a group of Belgian OH experts. In a third step, the guidelines were adapted in a more practical format, thanks to a working group involving OP’s coming from 12 OH services and medical advisors (MA) from the sickness funds. Results Two documents have been published with the support of the Belgian Ministry of Labor. The guidelines document (50 p) summarizes the scientific evidence according to the OP main missions : background information to be given to employers and employees, evidence-based prevention policies to promote in the enterprises. As regard the health surveillance of workers, the guidelines consider three situations: periodic health surveillance, spontaneous examinations at the worker request, and return to work examinations after long duration sick leaves. Secondly, a management guide (19 p) is intended for employers and trade unions representatives. Discussion From a health care policy point of view, this study highlighted the major roles of the occupational physician and of the sickness funds medical adviser and stressed the need to better define those roles if decision makers want to tackle the low back pain problem and the economic consequences of the related sick leave.

By combining electrospinning technique and layer-by-layer deposition, we produced a new material made of multilayered, chitosan-based nanofibers. Layer-by-layer (LBL) is a well known method for surface coating, based on electrostatic interactions. It enables the controllable deposition of a variety of polyions including synthetic and natural materials, with designable layer structure, defined wall thickness and size. Electrospinning (ESP) technique allows the fabrication of polymer fibers ranging from nanometers to a few microns in diameter, depending on the polymer characteristics (a.o. molecular weight, solution viscosity and conductivity) and processing conditions (electric potential, distance between syringe-capillary and collection plate, concentration, flow rate) (3). Mats of nanofibers produced by ESP display a very large surface area-to-volume ratio and high porosity with very small pore size. The nanometric scale of electrospun fibers also proves a positive effect on cellular growth, as fibers mats mimic extracellular matrix structure. The association of these two techniques with the use of biocompatible and biodegradable polymers such as chitosan, gives outstanding prospects in the field of biomedical applications, especially for the preparation of wound dressings, artificial skin or tissue engineering scaffolds. In the present study, a charged copolymer, poly(methylmethacrylate-block-methacrylic acid), was added to a poly(ε-caprolactone) or poly(D,L-lactide) solution before electrospinning in order to obtain charges on fibers surface. Oppositely charged polyelectrolytes – chitosan and poly(styrene sulfonate) or hyaluronic acid – were then alternately deposited on these aliphatic polyester fiber “cores” using LBL method. The aliphatic polyester core was also removed selectively to confirm the existence of a multilayered shell, obtaining hollow fibers. [less ▲]

Purpose: As part of a project aiming at higher specificity in clinical evaluations of the singing voice, singer perceptions were included and tested in conjunction with the voice range profile. Method: With a singer-patient group, the use of a commercial phonetograph supplemented by a hand-held response button was tested in a non-randomized study design. Button pressing during phonation resulted in marking specific regions of the voice range profile. 13 subjects, all singers with particular voice complaints, participated in enhanced voice range profile recordings. Singer-patients were asked to press a button to indicate sensations of vocal discomfort or instability during phonation. Each press was registered at the actual position in the voice range profile (VRP) so as to mark areas of difficulty. Data analysis was performed according to a method developed specifically for this use. Results: Subjects used the button during the course of tasking but did not demonstrate an increased button use when compared to a healthy group. Furthermore, numbers of button press repetitions within one task were often lower than those observed for the healthy group. The singer-patient group however demonstrated consistent behavior and tended to press the button in complete different areas of the VRP space. The location of the presses was dominantly in the interior of the VRP and concentrated within one specific range of the voice. Conclusion: The contribution of the button-VRP to clinical assessment of voice status in singers could represent a well needed resource for the clinicians but begs further development and work.

The aim of the project is the preparation of micellar nanocarriers made of biocompatibles copolymers and their structural analysis by Small Angle Neutron Scattering (SANS). These micelles could be used in drug delivery applications to fight cancer1. The hydrophobic polycaprolactone (PCL) core is intended to incorporate the drug. The corona of hydrophilic polyethylene oxide (PEO) stabilizes the nanocarriers with respect to the plasma proteins. The pH in the neighborhood of the tumoral cells is lower than in the healthy cells. We incorporated a pH-sensitive sequence of poly(2-vinylpyridine) (P2VP). As a result, these micelles are expected to deliver their drug near the cancerous cells without affecting the healthy cells. When the pH is acidic, the P2VP is protonated and the chains are repulsive. The micellar size is then larger than in basic pH, when the P2VP is precipitated on the PCL core. We prepared PCL65-b-P2VP31 / PCL65-b-PEO114 and PCL32-b-P2VP52 / PCL36-b-PEO114 50:50 mixtures of diblocks copolymers. The resulting mixed micelles are analyzed by SANS. We developed a theoretical model with a spherical water-free PCL core. The PEO corona is described as consisting of gaussian chains with a thickness estimated as twice the chain gyration radius, Rg. We propose two alternatives for handling the P2VP zone. The P2VP molecules are either assumed to be Gaussian chains or they fill a shell of thickness L with possible water penetration.The fitting of the models to the experimental scattering cross sections leads to important structural parameters like the aggregation number, the core radius, the gyration radius and the thickness of the P2VP shell.

In the last 10 years with the support of the Belgian Federal Public Service (FPS) for Employment and Labour and the European Social Fund, prevention advisors (PA) and occupational health physicians (OP) have been invited to use new methods for risk assessment involving workers’ participation, namely the Sobane strategy, or the Risk/Toxtrainer methodology. This study aimed at evaluating these methods actual use among PA’s and OP’s, and its impact on representations and risk management practices. Methods A national postal survey was conducted in 2007 among a random sample (n=3340) of all professionals registered as PA (>6000) or OP (about 1000) by the FPS. The questionnaire explored those professionals’ familiarity with 12 different risk assessments methods, the nature of their interventions in enterprises, their representations about participation and collected demographic information. Results A total of 859 completed surveys (response rate: 25.7 %) could be analyzed. Among the methods studied, the Kinney-Wiruth accident risk analysis is the most familiar (54% regular users + 19% trained ones). The participatory methods are familiar (users + trained) to respectively 46 % (Sobane) and 11% (Risktrainer) of the respondents. When analyzing practices in enterprises, the professionals familiar with one of the participatory approaches are more often than the other professionals suggesting the use of participation in risk management to colleagues (84 vs 67.5% ; p<0.000) or to the employer (84 vs 73.5% ; p<0.000). Those professionals not familiar with the participatory approaches agree more often with the following statements: “PA role is more to inform than to listen” (p=0.005), “Participatory processes are raising unrealistic expectations among the staff” (p=0.002). Discussion This study shows that participatory risk assessment methods are gaining ground in Belgian enterprises. It also highlights the significant influence that information and training in those methods have had on risk management practices and the professionals’ representations. [less ▲]

The main objective of vehicle powertrain hybridization is to improve the fuel consumption and environment pollutants impact (Eco-score) without decreasing the vehicle performances and other user satisfaction criteria. The Eco efficiency is a global index which accounts for both environmental impacts and user satisfaction. The Hybrid vehicles ability to overcome these two requirements depends on the optimal choice of their key mechanical, electric or hydraulic components. Some energy storage systems like ultra capacitors and hydraulic system are environmentally friendly and meet some user satisfaction criteria like daily cost, security, short charge/discharge duration and long life service. On the contrary, others like batteries have some times a environmental impact mitigate. The objective of this study is to establish a comparison between HEV (hybrid electric vehicle) and HHV(hybrid hydraulic vehicle) configuration by highlighting the effect of different energy storage systems (batteries, ultra capacitors, hydraulic system), mechanical and electric components sizes (engine, motors) upon the optimized HEV design taking care of both Eco-score and User satisfaction for different driving scenarios. The approach is formulated as a multidisciplinary optimization problem. At first, the HEV and HHV are modeled and simulated using ADVISOR (advanced vehicle simulator) with respect to several driving situations. Then emissions can be determined and the Ecoscore indicator can be calculated. User Satisfaction can be evaluated based on performance criteria extracted from ADVISOR simulation and on simple evaluation tools relying on the state-of-the art of technological information for safety, reliability and daily cost. The design problem is stated as follows: select mechanical, electric or hydraulic components (e.g. engine, motor and energy storage system sizes) to minimize the Ecoscore indicator and to maximize user satisfaction criteria subject to catalogue constraints on the choice of the components. The approach is illustrated on applications dealing with mild parallel hybrid buses. Results show that the hybrid electric buses using ultra capacitors have almost the same performances as those using batteries. However, the preferred choice would go towards super capacities because they have other appreciable properties compared to the batteries: the very high lifetime, high efficiency of charge and discharge and no polluting recyclability. Despite a smaller fuel saving than a HEV, the HHV technology has a chance to compete with HEV because of the hydraulic components low cost (industrial maturity), no pollutants recyclability due to the possible using of water as motor/pump fluid. HHV technology is a possible alternative in niche markets such as urban buses; bin-lorries or heavy urban delivery vehicles. [less ▲]

Repetitive finite element (FE) computations are needed when studying variations of geometrical and physical characteristics, which is the case for, e.g., parameterized analyses, optimisation, movement modelling, multi-physical coupling and model refinement. It is worth then benefiting from previous computations instead of starting a new complete solution for any new variation. A subproblem approach with perturbations of solutions is developed to efficiently tackle such repetitive computations. It consists in iteratively solving successive subproblems, the addition of their solutions giving the solution of a complete problem. At the discrete level, each subproblem is defined in its own domain and mesh, which decreases the problem complexity and allows distinct mesh refinements. A special attention is given to the proper discretization of the source constraints of each subproblem. This approach allows a natural progression from simple to elaborate models: from 1D to 3D geometries, from statics to dynamics, from low to high frequencies, from perfect to real materials, from linear to nonlinear materials, from initially simple models with magnetic or electric equivalent circuits to detailed geometrical models with the FE method, etc. Each model refinement can be quantified to justify its utility. A general frame is developed for electrostatic, electrokinetic, magnetostatic and magnetodynamic FE formulations, with their possible couplings. The perturbation method offers a way to follow the solution and its complexity through graphical representations and animations, which facilitates the understanding of the developed numerical tools as well as various physical behaviors. Numerous applications benefit from this sub-problem approach and will be presented. They concern magnetic circuits, skin and proximity effects, moving systems, eddy current non-destructive testing, magnetic screening, grounding systems, etc. [less ▲]

In the context of jobs executed on heterogeneous clusters or Grids, load balancing is essential. Indeed, a slow machine must receive less work than a faster one otherwise the overall job termination will be delayed. This is particularly true for Iterative-Stencil Applications where tasks are run simultaneously and are interdependent. The problem of assigning coexisting tasks to machines is called mapping. With dynamic clusters (where the number of machines and their available power can change over time), dynamic mapping must be used. A new mapping must be calculated each time the cluster changes. The mapping calculation must therefore be fast. Also, a new mapping should be as close as possible to the previous mapping in order to minimize task migrations. Dynamic mapping methods exist but are based on iterative optimization algorithms. Many iterations are required to reach convergence. In the context of a distributed implementation, many communications are needed. We developed a new distributed dynamic mapping method which is not based on iterative optimization algorithms. Current results are encouraging. Load balancing execution time remains bounded for tested cluster sizes. Also, a decrease of ~20% of the global available computational power of a cluster leads to ~30% of migrated tasks during load rebalancing. A new mapping is therefore close to the previous one.

Mon intention est de revenir sur un aspect tout à fait particulier du débat entre la phénoménologie et la psychologie de Natorp, à savoir l’écart entre une théorie « statique » et une théorie « génétique » des essences (eidè) ou, pour reprendre l’expression de Natorp, entre un « platonisme statique » et un « platonisme génétique ». Avec cette opposition en tête, j'examine le contentieux qui oppose Reinach à Natorp, à partir de la recension de la "Psychologie générale" rédigée par Reinach. Je focalise mon attention sur les thèses natorpiennes suivantes: (1) Le Je pur est inobjectivable et ne peut être décrit – à quoi Reinach objecte que le Je pur est une donnée phénoménologique, un phänomenologischer Befund; (2) La distinction entre acte et contenu est relative – à quoi Reinach objecte qu’elle est absolue; (3) La distinction entre contenu et objet est également relative – à quoi Reinach objecte que cette distinction est utilisée de façon équivoque mais doit être entendue comme absolue en un sens au moins.

In opposition to traditional machining in which part is manufactured by material removal, rapid prototyping techniques allow parts manufacturing by material addition. The part is built layer-by-layer and the sum of all layers creates the part. Currently, several techniques exist. They use different kind of materials (metals, ceramics, polymers) and technologies (laser melting, laser polymerising, 3D-printing, cladding, ...). Some of these techniques can deal with nanometric particles. In the case of which a near net shape part is built and must be sintered after shaping, the addition of nano-particles can be useful for sintering by increasing specific surface and reactivity of the batch or by improving the properties of the material. An overview about techniques of rapid prototyping allowing the processing of nanomaterials will be discussed. Tests have been done using Optoform process. This process uses a laser to polymerize a paste made of photo-curable resin loaded with powdered material. Nano-particles can be added and stabilized in the paste. In this presentation, the results obtained with both systems Al2O3 + nano Zr02 and SiC + Nano SiC will be discussed. [less ▲]

The main source of atmospheric mineral dust is the Sahara and its desertified margins that produce about half of the yearly global mineral dust. Saharan dust is often transported far away to the sources and causes air quality deterioration impacting northwards the Mediterranean and Europe, westwards crossing the Atlantic Ocean to the United States, the Caribbean and South America, and southwards to the Gulf of Guinea. Saharan dust storms can lead to particulate levels that exceed internationally recommended levels and transport allergens, including bacteria and fungi. Therefore special attention is paid to dust storms as such mineral particulate matter air pollution may be a serious health threat in various regions of the world because it may promote respiratory infection, cardiovascular disease and other ailments.

In various species a relationship between oocyte maturity and morphological characteristics of oocytes has been established. To our knowledge, immature oocyte aspect under light microscopy has been paid little attention in the equine. The aim of the study is to give a general description and analyse microscopic parameters of immature oocytes. Follicles from abattoir ovaries are punctured after measurement of their diameter and their cumulus-oocyte complexes are recovered. Different characters such as oocyte diameter, cumulus aspect, granulosity and polarity of ooplasm are observed under light microscopy. No correlation between estral activity, follicle maturity, cumulus cells aspect, polarity and granulosity of ooplasm was observed. Thickness of zona pellucida differs between oocytes with polar or non polar ooplasm. No correlation was observed between follicle diameter and oocyte diameter and none of the other studied parameters showed an influence on oocyte diameter. Results show that no character of oocytes observed under light microscopy can be related to follicular origin or to any other character. Further studies have to be done to compare these immature oocytes with mature oocytes and to find the ultra-structural origin of characters observed under light microscopy. [less ▲]

Simbol-X is a mission initially driven by the French and Italian space agencies. This is a formation flying satellite whose main interest is an unprecedented imaging and spectral capability, with a high sensitivity at energies between 10 and 80 keV. This space observatory is especially designed to study acceleration processes in astrophysical sources, along with extreme physics under relativistic conditions. I will briefly present the current status of the mission. I will also discuss prospects for future observations of massive stars with Simbol-X, aiming at probing the physics of particle acceleration in colliding-wind massive binaries. [less ▲]

Recent advances in the development of interferometric instruments coupled to long baseline facilities such as the VLTI allow us to observe astronomical targets at the milli-arcsecond scale. In the context of the study of massive stars, this new tool is likely to provide crucial information on the multiplicity of massive stars, and on interactions in colliding-wind binaries. In this context, our group is leading observation campaigns with the VLTI aiming at investigating massive multiple systems. I will briefly present these campaigns and discuss prospects for observations with next generation instruments such as the VLTI-Spectro-Imager (VSI). [less ▲]
