We consider a time independent one dimensional finite range and repulsive constant potential barrier between two impenetrable walls. For a nonrelativistic massi
In a recent paper we have studied the Hamiltonian and path integral quantizations of the conformally gauge-fixed Polyakov D1 brane action in the instant-form of
Many industries in the world take part in the pollution of the environment. This pollution often comes from the reactions of combustion. To optimize these react
