    Il y a quelques jours, Stephen Roach, économiste renommé, a publié un remarquable article d'opinion dans le "Financial Times". Il a esquissé un avenir de stagflation (faible croissance et de forte inflation) en raison de la fragilité croissante des chaînes et de la baisse de la demande des consommateurs que le confinement a imposée.Selon nous, Stephen Roach a fondamentalement tort. En substance, cet argument réitère la crainte de nombreux nouveaux économistes classiques qui s'inspirent de l'affirmation de Milton Friedman selon laquelle l'inflation est toujours un phénomène monétaire.

    European Research Area - Network on the Industrial Handling of Raw Materials for European Industries; roadmap of the "ERA-MIN" eranet; Non-energy and non-agricultural raw materials underpin the global economy and our quality of life. They are vital for the EU's economy and for the development of environmentally friendly technologies essential to European industries. However, the EU is highly dependent on imports, and securing supplies has therefore become crucial. A sustainable supply of mineral products and metals for European industry requires a more efficient and rational consumption, enhanced substitution and improved recycling. Recycling from scrap to raw materials has been rapidly gaining in quantity and efficiency over the last years. However, continuous re-use cannot provide alone the necessary quantities of mineral raw materials, due to i) recycling losses, ii) the worldwide growing demand in raw materials, and iii) the need of "new" elements for the industry. To fully meet future needs, metals and mineral products from primary sources will still be needed in the future. Most of them will continue to be imported from sources outside Europe; but others can, and should, be produced domestically. Advanced research and innovation are required to improve the capacity of existing technologies to discover new deposits, to improve the efficiency of the entire geomaterials life cycle from mineral extraction to the use as secondary resource of products at the end of their industrial life, and to reduce the environmental footprint of raw materials extraction and use. Research and innovation must be made to acquire knowledge as well, and to improve our basic understanding of all engineering and natural processes involved in the raw materials life cycle, as well as the coupling of these processes. Finally, research has to go beyond the present-day economic and technological constraints, and it should be closely associated with training and education in order to maintain existing skills and to share the most recent developments with the industrial sector. A long-term vision of research is necessary in order to have the capacity of evaluating the environmental and societal impacts of present and developing industrial activities and to imagine tomorrow's breakthrough concepts and technologies that will create new industrial opportunities. These objectives require the input of contrasted scientific and technical skills and competences (earth science, material science and technology, chemistry, physics, engineer, biology, engineering, environmental science, economy, social and human sciences, etc). An important challenge is to gather all these domains of expertise towards the same objective. The ERA-MIN Research Agenda aims at listing the most important topics of research and innovation that will contribute to i) secure the sustainable supply and management of non-energy and non-agricultural raw materials, and ii) offer opportunities of investment and employment opportunities in the EU.

    Le principal objectif de cette présente communication est de déterminer les conséquences de phénomènes complexes tel le couplage de la thermo- et photo-oxydation. Pour cette étude, nous nous sommes penchés sur le cas d'une gaine de polyéthylène chargée de noir de carbone et stabilisée avec un mélange classique d'antioxydants synergiques (Irganox 1010 + Irgafos 168), et ce après un vieillissement naturel d'un quart de siècle dans deux conditions d'ensoleillement distinctes: en présence et en l'absence de soleil (endroit sombre). The main objective of the present communication was to determine the consequences of such a complex thermo-photo-oxidation process in a polyethylene-carbon black sheath, stabilised with a classical synergetic antioxidant mixture (Irganox 1010 + Irgafos 168), after natural ageing during a quarter of century in two distinct sunshine conditions: in a presence and absence of sun (dark location).

    Crime and insecurity are deeply entrenched in some cities. While we have rankings of the most dangerous cities in the world, this does not give a clear picture of how and why dangerous spaces develop in cities. We are analysing case studies from cities in France, Colombia, Brazil and Australia to understand the factors that lead to insecurity, and to examine possible solutions.

    Work In Progress Session, VRIPHYS 2017: 13th Workshop on Virtual Reality Interaction and Physical Simulation, 23-24 April 2017, Lyon, France.; Cubic symmetric Mass-Spring Systems (MSS) for simulating isotropic elastic materials are known to be intrinsically limited by the Cauchy constraints (rari-constant theory) involving Poisson ratio of exactly ν = 1/4. To mitigate the impact of this restriction, we propose a new solution based on correction forces, which authorizes to use MSS for materials with ν ∈]0; 0.5[. The validation of our model is evaluated by comparing its response to various deformations with Finite Element Model (FEM). The results show that the proposed model is relevant to simulate any compressible isotropic elastic material, and in particular nearly incompressible (Poisson ratio ≃ 0.5) biological soft tissues for which it is dedicated.
