Social Media, Gender and the Mediatisation of War: Exploring the German Armed Forces’ Visual Representation of the Afghanistan Operation on Facebook

Studies on the mediatisation of war point to attempts of governments to regulate the visual perspective of their involvements in armed conflict – the most notable example being the practice of ‘embedded reporting’ in Iraq and Afghanistan. This paper focuses on a different strategy of visual meaning-making, namely, the publication of images on social media by armed forces themselves. Specifically, we argue that the mediatisation of war literature could profit from an increased engagement with feminist research, both within Critical Security/Critical Military Studies and within Science and Technology Studies that highlight the close connection between masculinity, technology and control. The article examines the German military mission in Afghanistan as represented on the German armed forces’ official Facebook page. Germany constitutes an interesting, and largely neglected, case for the growing literature on the mediatisation of war: its strong antimilitarist political culture makes the representation of war particularly delicate. The paper examines specific representational patterns of Germany’s involvement in Afghanistan and discusses the implications which arise from what is placed inside the frame of visibility and what remains out of its view

Etude expérimentale de la production de deutérons négatifs par double échange de charges dans le xénon

It is thought that additional heating of fusion plasma will result from D0 energetic beam injection in large plasma devices. Due to the fact that the conversion rate D+ to D0 rapidly decreases at high énergies, it seems that an interesting way to get these high energy neutrals should be : conversion of D+ to D-, acceleration of D- and further neutralization of D- to have D 0 at the desired energy. The efficiency of D+ to D- and D +2 to D- conversions at low énergies have been studied on a Xe gas target : it appears that D-/D+ conversion efficiency shows a smooth variation peaking slightly at 5 % for a D + energy of 5 keV. D-/D+2 increases up to 4 % at 12 keV and then decreases. It is shown that the agreement between sample calculation results and experimental values is quite fair for D -/D+.Dans la perspective du chauffage des plasmas de fusion, on envisage d'utiliser des faisceaux de deutérons D0 de grande énergie. Afin d'obtenir ces faisceaux, il convient de procéder à la conversion d'ions D+ en ions D-, ceux-ci devant être accélérés ultérieurement aux énergies intéressantes pour le chauffage. Les résultats présentés concernent donc l'évaluation du rendement de conversion D+ → D- et D+2 → D- en en fonction de l'énergie. La conversion D+/D- passe par un maximum à 6 keV (5 à 6 %), en accord raisonnable avec les estimations théoriques. La conversion D+2 /D- atteint une valeur de 2 à 3 % vers 12 keV. Pour ce dernier processus il n'existe pas, en l'état actuel, de modèle théorique. Les expériences ont été conduites dans le xénon, gaz cible du double échange de charge

Jules horowitz reactor update of the experimental capacity

International audienceThe Jules Horowitz Reactor (JHR) is a high performance Material Testing Reactor under construction in southern France (CEA/Cadarache research centre), that will carry out experimental irradiations for Nuclear Power Plants (NPP) and fuel vendors, utilities, safety organizations and research institutes. Therefore CEA is developing a set of test devices that will be operational for the start-up of the reactor or few years later. These experimental hosting systems will have to fulfil experimental needs concerning current NPP technologies (GEN II-III) and future reactors (GEN IV) as well. Experimental programs could be related to either fuel basis properties acquisition, mastering of margins or improvement of fuel products (clad and pellet), in term of performance, safety, maximum burn up, innovative materials or extension of validation domain of fuel performance codes.Then the present paper describes the main experimental hosting systems currently under design The MADISON device will be available at the JHR start up, and will allow testing the comparative behaviour of several instrumented fuel rods (from 1 up to 8 rods, of up to 60 cm fissile stack height) under NPP normal operating conditions (no clad failure expected). The ADELINE device will be available for the JHR start up, and will allow testing a single experimental rod up to its operating limits. The fuel rod will be tested under conditions that correspond to off-normal situations with possible occurrence of a clad failure. The first version so called ADELINE power ramps will focus on the clad failure occurrence during one of these abnormal situations.The LORELEI device will be available few years after the reactor start up and will allow testing a single rod under accidental situation that may lead to fuel damage. It will be able to reproduce all sequences of a LOCA-type transient, including the re-irradiation, the loss of coolant and the quenching phases, on a separate effect approach.In-core and in reflector material test devices are presented as well, corresponding to large ranges of irradiation conditions, in terms of temperature, neutron flux and neutron spectra. A special attention focuses on the improvement of the thermal stability and gradients in the interest zones of irradiated samples. Some specific devices are described such as equipments designed to the qualification of reactor pressure vessel steels (OCCITANE test device), to the studies of creep-swelling of structural materials (MICA test device) or to the study of the stress corrosion cracking assisted by irradiation phenomena (CLOE test device a corrosion loop with an accurate water chemistry monitoring for PWR or BWR requirement)

Electron capture from atomic hydrogen by multiply charged ions in low energy collisions

Cross section measurements and calculations are presented for electron capture by multiply charged ions from atomic hydrogen. The measurements were made for Nq+, Oq+ and Neq+ projectiles in the energy range 2 q to 10 q keV. Fair agreement is obtained with most earlier measurements when available. Molecular calculations, including translation factors, have been carried out for the case of fully stripped projectiles with charges between 5 and 10 as well as for O 6+(1s2) and N5+(1s2) impact The role of the interaction between the core and active electron is discussed Good agreement is obtained between theory and experiment. It is worth noting that both experimental and theoretical results do not show any oscillation as a function of the projectile charge in the energy range covered by the experiments.On a mesuré et calculé les sections efficaces de capture dans l'hydrogène atomique par des ions multichargés. Les expériences ont été faites avec les ions Nq+, Oq+ et Neq+ comme projectiles dans la gamme d'énergie 2 q à 10 q keV. On obtient en général un bon accord avec les mesures antérieures quand celles-ci sont disponibles. Les calculs utilisent la méthode moléculaire, avec facteurs de translation. Ils concernent les projectiles complètement épluchés avec une charge comprise entre 5 et 10 ainsi que O6+(1s2) et N5+(1s2). Le rôle de l'interaction cœur-électron actif est discuté. On obtient un bon accord entre la théorie et l'expérience. Tant les résultats expérimentaux que les résultats théoriques sont exempts d'oscillations en fonction de la charge du projectile dans le domaine d'énergie couvert par les expériences
