L'A.R. Plan National d'Urgence pour les risques nucléaires impose à l'exploitant de disposer de moyens d'évaluation des conséquences théoriques de rejets atmosphériques. Les modèles visent à permettre une évaluation rapide de la situation radiologique à proximité du site d'exploitation et la préparation d'un rapport communiqué aux autorités, concernant les conséquences potentielles. Le modèle MISTRAL (Modèle Intégré pour la Surveillance du Transport des Radioéléments dans l’Air par un modèle Lagrangien) a été construit début des années 1990 pour voir la possibilité d’utiliser des modèles de dispersion tri-dimensionnels pour calculer les conséquences radiologiques des rejets de radio-éléments dans l’atmosphère par les centrales électriques nucléaires. En effet, les modèles généralement utilisés pour ce calculs étaient de manière générale des modèles gaussiens supposant un sol plat, ce qui augmente fortement l’incertitude dans les zones avec relief (Tihange, Chooz par exemple). Le principe du modèle était le suivant : • Calcul du terme source sur base des mesures en continu réalisées aux centrales • Modèle de champ de vent tridimensionnel (UCL) ; 170 x 170 km • Modèle de dispersion lagrangienne ; 140 x 140 km, mailles « résultats » variables (100, 300, 1000m) o 3 groupes de radioéléments (gaz nobles, iodes, aérosols) o Déposition sèche et humide o Calcul de dose • Architecture informatique o Station de travail UNIX (DECStation 500/133) o Architecture Client/Serveur o DECServeur (collecte données senseurs) o Serveur environnement (Interrogation senseurs cheminées, distribution des données aux différents « clients ») o Serveur champ de vent (création champ de vent) • Interface utilisateurs o Interface semi-graphique o Développé à partir de librairies publiques • Modes de fonctionnement o Mode interactif : calculs « à froid », simulation de scénario prédéfinis o Mode automatique : tourne en permanence (temps réel) ; données d’entrée (vents, rejets) par capteurs o Mode prédictif : fait des prédictions à plusieurs heures en cas d’accident ; condition initiale = résultats mode automatique [less ▲]

Mithramycin (MTM), a cytotoxic compound, is currently being investigated for its anti-angiogenic activity that seems to be mediated through an inhibition of the transcription factor SP1. In this study we evaluated its anti-myeloma effects in the syngenic 5TGM1 model in vitro as well as in vivo. In vitro, MTM inhibited DNA synthesis of 5TGM1 cells with an IC50 of 400 nM and induced an arrest in cell cycle progression at the G1/S transition point. Western-blot revealed an up-regulation of p53, p21 and p27 and an inhibition of c-Myc, while SP1 remained unaffected. In rat aortic ring assays, a strong anti-angiogenic effect was seen, which could be explained by a decrease of VEGF production and an up-regulation of anti-angiogenic proteins such as IP10 after MTM treatment. The administration of MTM to mice injected with 5TGM1 decreased 5TGM1 cell invasion into bone marrow and myeloma neovascularisation. These data suggest that MTM displays anti-myeloma and anti-angiogenic effects that are not mediated by an inhibition of SP1 but rather through c-Myc inhibition and p53 activation. [less ▲]

This Chapter aims at delineating a proper ethical and legal response to the ‘dual-use dilemma’ of nuclear science and technologies. After assessing the different models of governance proposed so far for addressing the ‘dual-use’ feature of nuclear technologies, and based on precautionary, proactionary and cost/benefit approaches, it develops a framework based on the notion of ‘responsible stewardship’. This framework is based on a comprehensive analysis – through the involvement and cooperation, as much as possible, of all the stakeholders in the field – of both the advantages and the risks of the nuclear area, considering social, ethical, legal, environmental and political values. The policies then adopted are periodically and constantly revised (according to a ‘step by step’ principle) and based on the proportional balance of interests, values and rights at stake. A multilevel framework of sources and actors is involved in such a responsible process. A specific attention is devoted to the balance between the freedom to research and the security needs at the individual and at the State level, in particular focusing on Article IV of the Treaty of Non-Proliferation of Nuclear Weapons. Concrete ways for applying such model are explained, in particular with regard to the control of materials, education of people, and control of information. Finally, the historical steps in the governance of nuclear technologies are explored and some examples provided for the suggested approach. [less ▲]

The speech aims at delineating a proper ethical and legal response to the ‘dual-use dilemma’ of nuclear science and technologies. After assessing the different models of governance proposed so far in nuclear field for addressing the ‘dual-use’ feature of nuclear technologies, and based on precautionary, proactionary or cost/benefit approaches, it suggests the adoption of a framework based on the notion of ‘responsible stewardship’. This model entails: (a) a constant analysis of nuclear technology, both on the side of risks and of benefits, through the involvement and cooperation of all the stakeholders in the field (the involvement of both ‘top down’ and ‘bottom up’ actors, i.e. governments and scientific community); (b) the adoption of policies through ‘hard law’ and ‘soft law’ sources, which should be periodically revised, and based on the proportionality principle and the reasonableness one (with a balance among rights and freedom, from a constitutional viewpoint); (c) an ongoing communication, dialogue and interaction between actors in the nuclear area. A specific attention is devoted to the balance between the freedom to research and the security needs. Then, the concrete ways for applying such model are explained, in particular with regards to the issue of control of materials, education of people, and control of information. Finally, the historical steps in the governance of nuclear technologies and the positions of different religions addressing the issue have been explored, in order to provide some examples of the suggested approach.

The effects of the ionosphere remain one of the main factors which limit the precision and the reliability of many GNSS applications. It is therefore indispensable on the one hand to improve existing mitigation techniques and on the other hand to assess their remaining weaknesses. Mitigation techniques depend on the type of application considered. Therefore, specific mitigation techniques have to be developed. The paper summarizes work performed on this topic in the frame of WP 3.2 “Mitigation techniques” of COST296. [less ▲]

This paper presents a complete analysis of the aeroelastic behaviour of a deck section during the construction stage of the Third Bosphorus Bridge in Istanbul, Turkey. The combination of the low torsional stiffness along the vertical axis and the unstable aerodynamic shape of the suspended deck section led to a torsional flutter instability for a low wind speed (9.6 m/s). This low critical wind speed was obviously very likely to occur on the site of construction, so that mitigation actions were be implemented. It was decided to cover partially the sides of the deck section in order to modify adequately its aerodynamic shape. It is demonstrated that the proposed aerodynamic counter-measures increase the critical torsional flutter wind speed up to 39.5 m/s (worst configuration), which is acceptable for the construction phase of the bridge. The proposed mitigation solution was implemented and no torsional oscillations were observed. [less ▲]

Fossil fuel CO2 emissions result in climate change and ocean acidification. Enhanced weathering or artificial ocean alkalinization (AOA) has been proposed as a geoengineering method to mitigate further increase of atmospheric CO2 and decrease of ocean pH. A variant of AOA involves reacting carbonates and adding the dissolved materials into the upper ocean. The net effect of this approach is to increase ocean alkalinity, thereby increasing the oceanic capacity to store fossil fuel CO2. Another effect of adding alkalinity would be to drive seawater to higher pH values and thus counteract the ongoing ocean acidification. We test implications of AOA for marine carbon cycle using the global ocean biogeochemical model HAMOCC. In our model scenarios we add alkalinity in the amounts proportional to fossil fuel emissions. We show that large-scale AOA scenarios in which large amounts of alkalinity are added would be necessary to avoid a significant increase in atmospheric CO2 and to hold the global seawater pH close to today’s value. Even a short-term AOA would have long-lasting effects on seawater chemistry. When AOA stops, atmospheric CO2 (and pH) reverts back to rising (decreasing) at the rate determined by the fossil fuel CO2 emissions growth, but the effect of AOA is permanent. Hence, in contrast to SRM, effects of AOA on seawater chemistry and atmospheric CO2 retain after stopping alkalinity addition; AOA would not involve a long-term commitment. [less ▲]

La Responsabilidad Social Corporativa o RSC podría definirse como un compromiso (no vinculante) que asumen voluntariamente las empresas para con el desarrollo sostenible, el respeto a todos los recursos de trabajo y naturales, y las normas legales vigentes de los países receptores de empresas multinacionales. Concierne a todos los actores empresariales (stakeholders, shareholders, gobiernos, trabajadores, demás entes), lo que se ha venido acompañando por la consolidación de instrumentos que permiten medir el grado de responsabilidad social de las empresas. Mucho se ha difundido acerca del tema de la globalización y de la nueva distribución internacional que esta trajo consigo. Mucho se dijo, igualmente, acerca del hecho de que la prueba más contundente de su existencia es la presencia de compañías multinacionales a lo largo y ancho del planeta. Es definitivamente claro, y ya nadie se atreve a ponerlo en duda, que la globalización trajo consigo la eliminación de todas las barreras físicas para el desarrollo de los negocios en cualquier lugar del mundo. El mundo empresarial, dejó de tener límites. Hoy en día las compañías pueden establecer y desarrollar sus operaciones simultáneamente en diferentes partes del mundo si esa es su visión. Mediante un estudio comparativo de las acciones de RSC de cuatro compañías multinacionales en Colombia (dos del sector de la distribución al menudeo: CARREFOUR y MAKRO; dos del sector petrolero: OCCIDENTAL PETROLEUM COMPANY (OXY) y BRITISH Petroleum Company (BP)), se observa y analiza (desde un marco general) cómo los lineamientos de las actividades de estas cuatro multinacionales cumplen los principios de responsabilidad social universalmente aceptados y contenidos en la nueva certificación de RSC ISO26000. Esto nos ha permitido establecer si las multinacionales en Colombia están preparadas para el arribo de la certificación en cuestión. Aquí se entiende por acciones de RSC las contenidas en las declaraciones oficiales de dichas compañías al respecto de la Responsabilidad Social Corporativa. El criterio que define oficial en este sentido es la presentación pública de las mismas en espacios de acceso masivo a la información como la página web de esas compañías. Es así como desde un marco específico se busca demostrar que existen diferencias entre los aspectos privilegiados por las mismas y que dichas diferencias tienen que ver con el sector en el que se desarrolle su operación.
