摘要:Abstract(#br)The counterion condensation of mono- and divalent cations on the polyanion dextran sulphate (DS) was studied by conductometry and dye spectroscopy. The measurements were analysed using the limiting law for the conductance of polyelectrolytes and the two-variable...

摘要:Abstract(#br)The degree of complexation at saturation, ϕ s , and the equivalent electrostatic radius, R e , were determined for polyanion–polycation complexes composed of poly(acrylic acid)/ionene and poly(methacrylic acid)/ionene dissolved in water and aqueous alcoholic sol...

摘要:Abstract(#br)In homogenates of chromoplasts isolated from petals of Narcissus pseudonarcissus , violaxanthin is efficiently converted into a novel retro -carotenoid [(3 S ,5 R ,3′ S ,5′ R , all- E )-5,5′-dihydro-3,5,3′,5′-tetrahydroxy- β , β -carotene]. Here we hav...

摘要:Abstract(#br)Turbulence spreading, namely turbulent transport extending into a stable region is reported both for the flat density profiles in the far SOL and into a modeled H-mode barrier. It is shown that due to turbulence penetration, the pedestal width fluctuates and that its...

摘要:Abstract(#br)Turbulence in the scrape-off layer (SOL) is investigated using a 2D fluid model for the interchange instability as a paradigm. A constant driving flux governs the dynamics of both the equilibrium and fluctuating parts of the density and electric potential. The t...

摘要:Abstract(#br)Numerical analysis of the images in visible light from the JET tangential camera show that the edge localised mode (ELM) events are characterised by impacts on the low-field side components. The increase of emission is not restricted to the components closest to the ...

摘要:Abstract(#br)Cross-field transport in the SOL influences tokamak performance in particular regarding the divertor efficiency. Recent experiment evidence emphasizes non-exponential and/or flat SOL profiles that suggest a large perpendicular transport. A 2D fluid model based on the...

摘要:Abstract(#br)The effect of the ergodic divertor on the plasma edge in Tore Supra is to enhance the perpendicular transport through ergodization of the magnetic field lines [Ph. Ghendrih et al., Contrib. Plasma Phys. 32 (3&4) (1992) 179]. Nevertheless, the hot spots observed ...

摘要:Abstract(#br)The intermittent transport in the SOL is analysed in terms of the interaction between the average profile and the population of large transport events, the fronts. This provides the basis for the statistical analysis presented in this paper. Data from 2D numeric...
