✦ Synopsis

A mathematical model of the dynamics of radiocaesium transport in the aquatic phase-algae system is suggcstcd in this work. Allowance is made for algae growth and for both reversible and irreversible absorption of t>his rndionuclide by the algae. The algae biomass is divided hypothetically into two compartments with different exchange kinetics. The parameters of the model are time dependent. The model is quantified using experimental data for the concentrations of 137Cs in Cladophora glomerata filamentous algae and in water, obtained in situ in the environment of a nuclcar power station. Tho modcl fits the data rcasonably well and can be applied, for example, in bioindication of radioactivity in aquatic recipients in the environment of nuclear power stations.

## Abstract Drug‐eluting stents (DESs) are drug–device combination products that have been commercialized and demonstrated to be safe and efficacious in treating coronary artery disease. They have been very effective in reducing the extent of neointimal hyperplasia and therefore in preventing or mi
