Improvements on the Liége cyclotron have yielded an energy resolution comparable to that of classic electrostatic accelerators. The latest upgrades of the High-Energy High-Resolution beam line (HE-HR) are presented which consist of the addition of both a new extraction nozzle for non-invasive in-air measurements and a new particle-detection setup developed to take full advantage of the increased probed thickness with depth sensitive analytical methods. The suitability of the new setup and the advantages provided by the larger flexibility in choosing both the proper particle with an extended energy available will be illustrated by discussing latest results of studies recently led on Roman gilding techniques on cultural heritage artifacts by means of “High-Energy” alpha backscattering spectrometry combined with PIXE.

Le Syndrome de Désadaptation PsychoMotrice (SDPM) représente une entité clinique typiquement gériatrique. Il regroupe des troubles posturaux tels que la rétropulsion du corps, des troubles de la marche peu spécifiques, des signes neurologiques comme une akinésie axiale et une hypertonie, ainsi que des troubles psychocomportementaux proches de ceux retrouvés dans la dépression. Son diagnostic repose tant sur la clinique que sur les données iconographiques. Ce syndrome cause des chutes qui occasionnent un sentiment d’insécurité chez la personne âgée. Celle-ci se dévalorise, risque de se replier sur elle-même et de perdre son autonomie et tout contact social. Dans cet article, nous évoquerons brièvement la physiopathologie, tenterons de rappeler les outils diagnostiques et proposerons une prise en charge des patients souffrant de ce syndrome. [less ▲]

The authors consider a power system composed of several non-synchronous AC areas connected by a multiterminal high-voltage direct current (HVDC) grid. In this context, the authors propose a distributed control scheme that modifies the power injections from the different AC areas into the DC grid so as to make the system collectively react to load imbalances. This collective reaction allows each individual AC area to downscale its primary reserves. The scheme is inspired by algorithms for the consensus problem extensively studied by the control theory community. It modifies the power injections based on frequency deviations of the AC areas so as to make them stay close to each other. A stability analysis of the closed-loop system is reported as well as simulation results on a benchmark power system with five AC areas. These results show that with proper tuning, the control scheme makes the frequency deviations converge rapidly to a common value following a load imbalance in an area. [less ▲]

Analytical methods capability evaluation can be a useful methodology to assess the fitness of purpose of these methods for their future routine application. However, care on how to compute the capability indices has to be made. Indeed, the commonly used formulas to compute capability indices such as Cpk, will highly overestimate the true capability of the methods. Especially during methods validation or transfer, there are only few experiments performed and, using in these situations the commonly applied capability indices to declare a method as valid or as transferable to a receiving laboratory will conduct to inadequate decisions. In this work, an improved capability index, namely Cpk-tol and the corresponding estimator of proportion of non conforming results ( ) is proposed. Through Monte-Carlo simulations, they have been shown to greatly increase the estimation of analytical methods capability in particular in low sample size situations as encountered during methods validation or transfer. Additionally, the usefulness of this capability index is illustrated through several case studies covering applications commonly encountered in the pharmaceutical industry. Finally a methodology to determine the optimal sample size required to validate analytical methods is also given using the proposed capability metric. [less ▲]

Introduction Un acide gras (AG) est un acide carboxylique avec une longue chaine aliphatique, qui peut être saturé ou insaturé. Récemment, le rôle des AG, particulièrement, celui des oméga-3 et oméga-6, a émergé comme facteur de risque cardiovasculaire dans la littérature. Le but de ce travail était de comparer les taux d’AG mesurés dans une population saine avec ceux obtenus chez des patients admis aux urgences pour un infarctus du myocarde. Matériels et méthodes Cinquante quatre sujets sains (33±11ans, 31 femmes) ont été sélectionnés comme population de référence. Ces derniers ont été sélectionnés selon leur mode de vie (alimentation, tabac, etc). En parallèle, nous avons dosé les AG chez 33 patients (55±9 ans, 12 femmes) admis dans le service d’urgence de notre institution pour infarctus aigu du myocarde (AMI). Le sang était prélevé sur EDTA. Avant l’analyse, les échantillons étaient lavés et transméthylés. Le dosage des AG était réalisé par chromatographie gazeuse couplée à un détecteur à ionisation de flamme (GCFID). Après le dosage, nous avons réalisés une comparaison des taux, sommes et rapport entre les différents AG ainsi que l’index oméga-3 (somme de l’acide eicosapentaénoïque et docosahexaénoïque) obtenus dans les 2 groupes. Résultats. Des valeurs de référence ont été obtenues pour notre population de référence via le logiciel de statistique MedCalc. Dans le groupe AMI, les taux d’oméga-6 étaient significativement plus élevés (p<0.05) pour C18:2n6 (Figure 1) et C18:3n6 (Figure 2)comparés aux résultats obtenus dans la population de référence. Par contre les taux d’oméga-3 étaient significativement plus bas (p<0.01) par rapport aux sujets de référence pour le C22 :6n3 (Figure 3). L’index oméga-3 montrait une valeur plus basse et le rapport oméga-6/oméga-3 était plus élevé dans le groupe AMI comparé aux sujets de référence. Conclusion Le dosage des AG est un nouvel outil que le laboratoire peut proposer aux cliniciens afin de stratifier les patients présentant le plus de risque cardiovasculaire avant ou après un infarctus du myocarde. Ces patients pourraient ainsi être supplémenté en acides gras oméga-3 afin d’éviter les récidives d’infarctus du myocarde ou de diminuer la formation de la plaque d’athérosclérose avant le premier accident.

Physical modeling and numerical modeling are two efficient analysis approaches in hydraulic engineering. The interactive application of both methods is obviously the more effective response to most flow problems analyses. This paper presents the results of a successful application of such a composite numerical – physical study carried out by the Research Group Hydraulics in Environmental and Civil Engineering (former HACH) of the University of Liège on behalf of Coyne et Bellier (Tractebel Engineering). It concerned, at the stage of detailed draft, the hydraulic study of the Taoussa Project on the Niger River in Mali. The studies, performed in less than 6 months, focused on the flow characteristics at the scale of the reservoir and the river, using the numerical approach, as well as on hydrodynamic details in the spillway using a large scale factor physical model with boundary conditions defined on the basis of numerical modeling.

The performance of several Internet applications often relies on the measurability of path similarity between different participants. In particular, the performance of content distribution networks mainly relies on the awareness of content sources topology information. It is commonly admitted nowadays that, in order to ensure either path redundancy or efficient content replication, topological similarities between sources is evaluated by exchanging raw traceroute data, and by a hop by hop comparison of the IP topology observed from the sources to the several hundred or thousands of destinations. In this paper, based on real data we collected, we advocate that path similarity comparisons between different Internet entities can be much simplified using lossy coding techniques, such as Bloom filters, to exchange compressed topology information. The technique we introduce to evaluate path similarity enforces both scalability and data confidentiality while maintaining a high level of accuracy. In addition, we demonstrate that our technique is scalable as it requires a small amount of active probing and is not targets dependent. [less ▲]

Echocardiography has become a routine non invasive cardiac diagnostic tool in most species. Accurate measurement of cardiac dimensions requires reference values, which are poorly documented in goats. The aim of this study was to test the inter-day repeatability and to establish the reference values of two-dimensional (2D-) and time-motion (M-) mode echocardiographic variables in healthy adult Saanen goats. Six goats were investigated three times by the same observer at one day interval using a standardized 2D- and M-mode echocardiographic protocol. The intra-observer inter-day repeatability was tested using analysis of variance, calculation of the coefficient of variation and confidence intervals. A single echocardiographic examination was performed in 6 other goats, and values obtained in the 12 goats were used to establish the 2D- and M-mode echocardiographic reference values in healthy adult female Saanen goats. Statistical analysis revealed a good inter-day repeatability of the echocardiographic cardiac measurements. Echocardiographic reference values obtained in healthy adult Saanen goats seemed slightly higher than those reported in healthy Swedish domestic goats and were similar to those reported in healthy adult sheep.

Studies on nationalism were often interested with the city, especially the city centers. The politics of heritage, the architecture of public buildings and the design and use of central public spaces are often studied in relation to national identity politics. Municipal politics of the historical city in the face of central authorities’ urban politics is also frequently approached in the light of Nation-State building issues. If no doubt the consideration of city centers as a vantage point for understanding the relation between nationalism and the city is an interesting one that bore many fruits, we believe that a vantage point concentrating on the peripheries can highly contribute in unveiling other aspects of this relation. This paper aims at investigating the potentialities of this contribution. As the place where urbanization is taking place, the periphery is: - Where the national identity construction logic is put to test. First because, historically, it is here where the confrontation between the urban and the rural did first take place. Second, because rural exodus and migration, usually more important in the periphery, will continue to challenge it. - Where the city and the hinterland get connected through different national territory building networks. - Where the Nation-State central authorities will find the largest land reserves to develop their large emblematic projects. - Where urban fragmentation poses the strongest challenge to the unitarian message of nationalism, but also is where some nationalist movements might best develop In fact, the periphery represents equally a fertile ground for nationalism and for resistances to it. This paper will rely on the city of Beirut as a case study. [less ▲]
