This paper presents a new proposal for beam-column interaction formulae initially based on second-order in-plane elastic theory, as an alternative to those proposed in the Eurocode 3 pre-standard [1]. It has been derived according to the following requirements: theoretical background, clear physical meaning, consistency with the other related formulae of Eurocode 3 and accuracy. Besides that, the suggested formulae cover all required continuities: between the cross-section classes, from plasticity to elasticity as slenderness and axial force increase, and continuity between all the individual stability member checks and cross-section verifications. Further to the presentation of the formulae and their background, the good agreement of the proposal is shown through an extensive comparison with more than 15,000 results of finite element numerical simulations.

The combination of budesonide 160 micrograms/formoterol 4.5 micrograms (Symbicort TH) in the same dry powder inhaler (turbohaler) results in a drug that possesses powerful bronchial anti-inflammatory, bronchoprotective and bronchodilating activities. Symbicort TH is registered as a maintenance treatment for asthma from the age of 12 years. This drug is indicated in the treatment of moderate and severe persistent asthma as well as in asthma which remains mild persistent despite the regular use of low doses of inhaled corticoids alone. Symbicort TH rapidly improves asthma control by reducing symptoms, relief medication consumption and by improving lung function. Importantly, when taken regularly over a prolonged period, the drug reduces the number of mild and severe exacerbations. The dose of Symbicort TH is adjustable according to the disease severity and generally fluctuates between 2 x 1/24 h and 4 x 2/24 h. Symbicort TH is a simple and a efficient treatment likely to improve the compliance of asthmatics to their treatment in real life. [less ▲]

Le transport est une activité socio-économique fondamentale qui joue un rôle complexe et multiple dans le fonctionnement et dans le mécanisme du développement d’un pays ou d’une région. Une bonne marche couronnée de succès du système économique et social d’une région est en effet étroitement liée au transport de qualité organisé rationnellement. Sur base de ces considérations, il est clair que l’activité « transport » intègre un grand nombre de composantes et son impact déborde largement les seuls utilisateurs. A cet aspect pluridisciplinaire de l’activité « transport », il faut ajouter son évolution vers des solutions intermodales ; il faut en effet dépasser la simple organisation de la concurrence pour assurer la complémentarité des modes de transport, ce qui naturellement génère l’émergence de la logistique intégrée devenue une activité majeure pour tendre vers un optimum du transfert origine-destination. Dans une perspective de concurrence intermodale équitable, il convient que l’évaluation comparative se fasse sur un plan socio-économique, tenant compte à la fois des coûts internes et externes. Il faut mobiliser les différents niveaux de pouvoir et de compétence et veiller particulièrement à ce que les avancées en matière de libéralisation et de mise en concurrence et les politiques sectorielles s’inscrivent pleinement dans l’objectif d’une mobilité durable. Ces principes de base ont sous-tendus la présente analyse du « Pôle Transport de la région liégeoise » relative à l’opportunité de transférer du conteneur du port de Liège (plate-forme de Renory) vers les ports d’Anvers et de Rotterdam, principalement par la voie d’eau, alors qu’actuellement ce transfert est réalisé par la route.

Le mélèze a été introduit en Belgique dans la deuxième moitié du XVIIIe siècle. Il s’agissait alors du mélèze d’Europe, surtout implanté à des fins esthétiques ou d’enrichissement de forêts feuillues. Quant au mélèze du Japon, il a été importé en Europe à la fin du XIXe siècle. Ce n’est qu’à partir des années ’50 que les mélèzes ont eu du succès auprès des sylviculteurs. Ils l’ont planté le plus souvent par parquets purs après d’autres résineux ou en transformation de peuplements feuillus de faible qualité sylvicole. Mais comme le montrera l’inventaire forestier wallon en 1980, ce succès fut de courte durée. [less ▲]

The self-sustained tone generated by a low Mach number free flow impinging on a slotted plate, usually referred to slot-tone, is experimentaly studied. In this work we focus on its coupling with the pipe from which the jet flows out. The jet nozzle and the beveled slot are aligned and have the same large aspect ratio. The tones generated have a single well defined frequency (around 1 kHz), a high amplitude (typically, 105 to 115 dB) and exhibit typical characteristics of self-sustained tones. Their frequencies are about the same order of magnitude than the natural frequency of the shear layer calculated from the linear stability theory. For some Reynolds numbers and some plate distances, a standing wave pattern is observed in the pipe. The outer and inner acoustic fields show high coherence and the slot-tone locks on a pipe eigenmode, which indicates an acoustic feedback. However, especially for lower Reynolds numbers, this coherence vanishes but the self-sustained tones are still present. It suggests that the hydrodynamic feedback becomes preponderant. [less ▲]

Angiogenesis, a key step in many physiological and pathological processes, involves proteolysis of the extracellular matrix. To study the role of two enzymatic families, serine-proteases and matrix metalloproteases in angiogenesis, we have adapted to the mouse, the aortic ring assay initially developed in the rat. The use of deficient mice allowed us to demonstrate that PAI-1 is essential for angiogenesis while the absence of an MMP, MMP-11, did not affect vessel sprouting. We report here that this model is attractive to elucidate the cellular and molecular mechanisms of angiogenesis, to identify, characterise or screen "pro- or anti-angiogenic agents that could be used for the treatment of angiogenesis-dependent diseases. Approaches include using recombinant proteins, synthetic molecules and adenovirus-mediated gene transfer. [less ▲]

The dissertation focuses on multiple (or parallel) proceedings in private international litigation. In international civil disputes it is not unusual that jurisdiction for a particular dispute exists in several countries. In that case, each party may be tempted to start litigation in the forum most favorable to it, for example to take advantage of the forum’s more generous recovery rules or the extended possibilities of discovery. Similarly, one party can also choose to initiate proceedings in different countries for the same dispute. The question arises how the legal systems involved will and should deal with such ‘multi-fora’ disputes. The first question addressed is whether and to what extent the international legal community should strive to prevent and/or eliminate such duplicate proceedings. It is undubitable that multiple proceedings could lead to undesirable consequences, such as conflicting judgments. Concurrent jurisdiction also brings about a waste of (scarce) judicial resources, and unnecessary expenses for the litigants. To prevent altogether parallel proceedings from happening however, seems at best utopic or even dangerous. Even if the international community were to achieve a global agreement on a comprehensive set of jurisdiction rules, one cannot imagine that there rules would designate one and only one court for each particular dispute. The desire to concentrate jurisdiction for all related disputes in the hands of one court is indeed but one of the numerous factors influencing the allocation of jurisdiction in international matters. The dissertation therefore undertakes to study the rules and instruments that can be used to resolve parallel litigation once multiple proceedings have been issued. The study learns that courts can adopt a variety of attitudes when faced with parallel litigation. A legal system can decide to ignore altogether the fact that a foreign court is seised of parallel proceedings, relying on the res judicata effect of the first decision to be rendered. It can also decide to abstain from taking up the case in deference to the foreign proceedings. Finally it can try to put an end to the parallel proceedings, by enjoining a party from further proceeding before the foreign court. After an in-depth analysis of these different policies and of the various rules and instruments in which they are embodied, my conclusion is that the preference should be given to mechanisms whereby one court voluntarily declines jurisdiction in favor of the other. The preference I express for a mechanism of ‘international abstention’ is however qualified. Whether or not a court declines jurisdiction in favor of a foreign court, will depend inter alia on the confidence it has that justice will be done in the foreign forum. Even with a minimum level of trust and confidence between jurisdictions, the abstention rule can follow different models, from the continental lis alibi pendens rule, which offers almost automatic priority to the court first seised, to the common law doctrine of ‘forum non conveniens’, where priority goes to the more appropriate forum. Between these two extremes lies a world of nuances. The dissertation therefore attempts to formulate an abstention rule which will reconcile these seemingly opposed visions and explain in which circumstances and under which conditions a court should or can decline jurisdiction in deference to litigation pending before a foreign court.

Canonical activation of NF-kappaB is mediated via phosphorylation of the inhibitory IkappaB proteins by the IkappaB kinase complex (IKK). IKK is composed of a heterodimer of the catalytic IKKalpha and IKKbeta subunits and a presumed regulatory protein termed NEMO (NF-kappaB essential modulator) or IKKgamma. NEMO/IKKgamma is indispensable for activation of the IKKs in response to many signals, but its mechanism of action remains unclear. Here we identify TANK (TRAF family member-associated NF-kappaB activator) as a NEMO/IKKgamma-interacting protein via yeast two-hybrid analyses. This interaction is confirmed in mammalian cells, and the domains required are mapped. TANK was previously shown to assist NF-kappaB activation in a complex with TANK-binding kinase 1 (TBK1) or IKKepsilon, two kinases distantly related to IKKalpha/beta, but the underlying mechanisms remained unknown. Here we show that TBK1 and IKKepsilon synergize with TANK to promote interaction with the IKKs. The TANK binding domain within NEMO/IKKgamma is required for proper functioning of this IKK subunit. These results indicate that TANK can synergize with IKKepsilon or TBK1 to link them to IKK complexes, where the two kinases may modulate aspects of NF-kappaB activation. [less ▲]
