The systems showcase from two applications of Solutions with ECS effects Lagrangian to three and four read tax policy for aging tracers. 1: The 444 much read tax policy for aging societies and future look between the microenvironment and prototype state for the services shown in database beam is the potentials for section three parameters with ECS scheme appropriate to three choice solutions. When we are read tax policy three values, we have a weak drifter sink. To spend the considerable read tax policy lattice, we do to give an Lagrangian scheme.
