This paper is concerned with the study of the existence/non-existence of the discrete spectrum of the Laplace operator on a domain of which consists in a twisted tube. This operator is defined by means of mixed boundary conditions. Here we impose Neumann Boundary conditions on a bounded open subset of the boundary of the domain (the Neumann window) and Dirichlet boundary conditions elsewhere.
