With the development of a fusion reactor the investigation of the interaction between the hot plasma and the wall is one of the most important tasks. The solution of the wall erosion problem due to high power and particle flux from the plasma onto the divertor target is a major challenge. Detached plasmas appear to be favourable with respect to a r...

In recent H-mode experiments at JET with giant ELMs a lateral deflection of hot tokamak plasma leaving the scrape-off layer and striking the divertor plate has been observed. This deflection can effect the divertor erosion caused by the hot plasma irradiation, because of enlarging the irradiated area. A simplified MHD model of the vapor shield plas...

Suspended matter (SM) from the Nyong basin (Cameroon, Africa), a tropical watershed, was collected by tangential flow ultrafiltration to separate particulate (greater than 0.45 microm) and colloidal (less than 0.45 microm ; greater than 20 kDa) fractions. In this basin, two distinctive systems in a selected small catchment (Nsimi-Zoétélé) of the Ny...
Les problèmes d'érosion sont fréquents en Afrique, mais l'importance relative des différents processus varie d'une région écologique à une autre. Ainsi en Algérie, l'érosion en nappe est modeste, même sur forte pente, tandis que le ravinement et les mouvements de masses mobilisent des volumes considérables de terre. Dans cette synthèse, les auteurs...
