In particular, we discuss a simple quiver theory for a Pati-Salam like model, as an example in which the calculations of exotic instantons' effects are simple and controllable. We discuss some different possibilities in order to generate $n-\\bar{n}$ oscillation testable in the next generation of experiments, Majorana mass matrices for neutrini and a Post-Sphaleron Baryogenesis scenario.
