$$\int_{\mathrm{0}} ^{\infty} {e}^{−\left({s}+\mathrm{1}\right){t}} \sqrt{{t}}\:{dt}\:\:\:\:\: \\ $$$$=\frac{\mathrm{1}}{\left({s}+\mathrm{1}\right)^{\frac{\mathrm{3}}{\mathrm{2}}} }\Gamma\left(\frac{\mathrm{3}}{\mathrm{2}}\right)=\sqrt{\frac{\pi}{\mathrm{4}\left({s}+\mathrm{1}\right)^{\mathrm{3}} }} \\ $$
