Associated primes of Local cohomology modules over Regular rings

Let $R$ be an excellent regular ring of dimension $d$ containing a field $K$ of characteristic zero. Let $I$ be an ideal in $R$. We show that $Ass
H^{d-1}_I®$isafiniteset\mathrm{.}Asanapplicationweshowthatif$I$ is an ideal of height $g$ with $heightQ=g$ for all minimal primes of $I$ then for all but finitely many primes $P\supseteq I$ with $heightP\ge g+2$, the topological space $Spe{c}^{\circ }(R_P\mathrm{/}I{R}_P)$ is connected.
