  In the domain of Nuclear reactions at intermediate energies, the QCD coupling
constant $\alpha_s$ is large enough ($\sim$ 0.3 - 0.5) to render the
perturbative calculational techniques inapplicable. In this regime the quarks
are confined into colorless hadrons and it is expected that effective field
theories of hadron interactions via exchange of hadrons, provide useful tools
to describe such reactions. In this contribution we discuss applications of one
such theory, the effective Lagrangian model, in describing the hadronic
reactions at intermediate energies whose measurements are the focus of a vast
international experimental program.
