    Mémoire de stage; The use of adhesively bonded composite reinforcement for steel structures induce a closer study of the adhesive as it is considered the weakest point in the assembly. A reliable numerical damage model has been developed for the adhesively bonded joints and then verified for different types of configurations. A bi- linear traction separation description of a cohesive zone model was used in ABAQUS to simulate the damage evaluation in the adhesive. It was then compared to experimental results for the global structure behavior (local strains, applied load, applied displacement).; L'utilisation des renforcements par composites collés pour des structures métalliques implique une étude plus approfondie des adhésifs puisqu'il s'agit dans ce cas de l'élément le plus faible dans l'assemblage. Un modèle d'endommagement numérique a été développé pour le joint collé étudié et appliqué pour diffèrent type de configurations. Le modèle bi linéaire de traction- séparation (modèle de zone cohésives) est réalisé sur ABAQUS pour visualiser l'évaluation de l'endommagement de l'adhésive et pouvoir réaliser une comparaison avec les investigations expérimentales (déformation locale, effort appliqué, déplacement appliqué).

    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).

    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.

    Rapport de recherche; This summary report presents the main results of WP3 "Types of Factors" of the TRACE Project. The work as performed in the tasks 3.1 (accident related factors), 3.2 (sociological and cultural factors), 3.3 (trip-related factors), and 3.4 (driving-task associated factors) and presented in the Deliverables 3.1 to 3.4 and an additional INTERNAL TRACE Reports (Collection of Sub-Reports) is summarized and discussed. The objectives of analysing traffic accident causation : from a factor's point of view while taking traditional views into account ; on different levels ; by using statistic methods for existing databases as provided by the WP3 Partners and ; by using new (developed in WP5 of the TRACE project) methods on new case analysis ; in order to gain new knowledge on accident causation was possible to reach. The scope of the identified key aspects as found by the Partners in their work for the relevance in EU27 is discussed. In accordance, even further, appropriate suggestions for prevention of traffic accidents can be derived.

    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.
