  Let $R$ be a right and left Ore ring, $S$ its set of regular elements and $Q
= R[S^{-1}] = [S^{-1}] R$ the classical ring of quotients of $R$. We prove that
if F.dim$(Q_Q) = 0$, then the following conditions are equivalent: $(i)$ Flat
right $R$-modules are strongly flat. $ (ii)$ Matlis-cotorsion right $R$-modules
are Enochs-cotorsion. $(iii) $ $h$-divisible right $R$-modules are
weak-injective. $(iv)$ Homomorphic images of weak-injective right $R$-modules
are weak-injective. $(v)$ Homomorphic images of injective right $R$-modules are
weak-injective. $(vi)$ Right $R$-modules of weak dimension $ \le 1$ are of
projective dimension $\le1$. $(vii)$ The cotorsion pairs
$(\mathcal{P_1},\mathcal{D})$ and $(\mathcal{F}_1,\mathcal{WI})$ coincide.
$(viii)$ Divisible right $R$-modules are weak-injective. This extends a result
by Fuchs and Salce (2017) for modules over a commutative ring $R$.
