For instance, in the case that~$\TT$ is the theory of commutative rings with unit and~$A$ is the -ring~$\QQ$ of integers, we have~$\Spec(A^\sim) \cong \Spec(0^\sim)$, where~$0$ -is the zero ring, as~$\QQ$ allows ring homomorphisms only in those finitely +ring~$\QQ$ of rational numbers, we have~$\Spec(A^\sim) \cong \Spec(0^\sim)$, where~$0$ +is the zero ring, as~$\QQ$ allows ring homomorphisms only to those finitely presented rings in which~$1 = 0$ holds. Hence~$A^\sim$ and~$(U_\TT)^{\Spec(A^\sim)} \cong (U_\TT)^{\Spec(0^\sim)} \cong 0^\sim$ do not coincide. \end{rem}
