Moncler Stockists Leeds with protons were compared with calculations
Measurements of the spectral Buy Moncler Coats fluence and the ambient dose equivalent of secondary neutrons produced by 250 GeV/c protons and 158 GeV/c per nucleon lead ions were performed at CERN around a thick beam dump. The experimental results obtained with protons were compared with calculations performed with the FLUKA Monte Carlo code. As the available Monte Carlo codes do not transport particles with mass larger than one atomic mass unit, it is shown that for high energy heavy ions, estimates can be carried out by scaling the result of a Monte Carlo calculation for protons by the projectile mass number. The moving finite element collocation method proposed by Kiil et al. (1995)Chem. Engng Sci. 51 (4), 2793–2799 for solution of problems with steep gradients is further developed to solve transient problems arising in the field of adsorption. The technique is applied to a model of adsorption in solids with bidisperse pore structures. Numerical solutions were Moncler Stockists Leeds found to match the analytical solution when it exists (i.e. when the adsorption isotherm is linear). The method is simple yet sufficiently accurate for use in adsorption problems, where global collocation methods fail.
