11. Birchas Hagomel:[1]

An Avel may recite the blessing of Hagomel during Shiva, although he may not receive an Aliyah to the Torah for its sake. [Some Poskim[2], however, conclude that if there are only three days remaining to the Shiva then it is better for the mourner not to recite the blessing of Hagomel during Shiva.]
