During tokamak operation, Plasma Facing Components (PFC) are exposed to high heat load from plasma radiation and particle overflow. Thus, materials forming the PFC armor are eroded in high flux areas and deposited in low flux areas, in form of layers, more or less thick and sticky. These layers can pollute the plasma discharge, and above all trap a part of(More)
In fusion devices, like Tore Supra, the surface temperature of the carbon plasma facing components (PFC) is measured by standard infrared (IR) system in real time for control of integrity of PFCs. The emissivity of carbon is known and high (ε~0.8-0.9) and therefore the contribution of the reflected flux in the total flux collected can be neglected.(More)
The treatment of recalcitrant multiple verrucae by sensitization to DNCB has been successfully used as shown in a previous study. Owing to the mutagenic effect of DNCB in Ames test, we tried a new non-mutagenic compound, SADBE to treat patients with multiple recurring warts. The study comprised 18 patients whose informed consent was obtained. They were(More)
In nuclear fusion devices, such as Tore Supra, the plasma facing components (PFC) are in carbon. Such components are exposed to very high heat flux and the surface temperature measurement is mandatory for the safety of the device and also for efficient plasma scenario development. Besides this measurement is essential to evaluate these heat fluxes for a(More)
The treatment of recalcitrant multiple verrucae vulgaris remains puzzling. Recent studies have demonstrated the relationship between the DNCB-induced cell mediated immunity and the resolution of warts. Our study consisted of 27 patients. Among them, 22 were sensitized to DNCB. A complete resolution of warts occurred in 81 p. 100 with minor side effects(More)
On fusion experimental reactors, in-vessel remote operations will be mandatory to allow maintenance interventions and limit personal radiation exposures. In addition, mini-invasive robotics inspections will be required between plasma pulses for safety issues management or to assist the scientific programs. These remote-controlled devices will have to offer(More)
The authors describe their methodology—dissection, photography, informational—permitting a biomechanical approach together with the study of the changes in the topographic anatomy of a region during movement. Les auteurs exposent leur méthodologie—dissection, photographie, informatique—permettant une approche biomécanique ainsi que l'étude de l'évolution de(More)
in cuvettes with their longitudinal dimension parallel to the light beam, while under the influence of a centrifugal force, has many advantages that are not immediately apparent. This survey summarizes the advantages in comparison to cuvettes standing with their long axis perpendicular to the light beam: in the latter the pathlength is fixed by the(More)
Observations on the hemodynamic properties of a thiophanium derivative (Arfonad) have been made on normotensive nonpregnant and pregnant subjects and on patients with hypertensive complications of pregnancy. The drug was given by single intravenous injections and by intravenous drip infusion. The hypotensive effects of single injections where compared with(More)
