this article presents a unified approach to the abstract notions of partial convolution and involution in $l^p$-function spaces over semi-direct product of locally compact groups. let $h$ and $k$ be locally compact groups and $tau:hto aut(k)$ be a continuous homomorphism.  let $g_tau=hltimes_tau k$ be the semi-direct product of $h$ and $k$ with respect to $tau$. we define left and right $tau$-c...

in this paper‎, ‎we determine the simple groups $g=ab$‎, ‎where $b$ is isomorphic to $l_{3}(4)$ and $a$ isomorphic to an alternating or a symmetric group on $ngeq5$‎, ‎letters‎.

This study attempted to systematically inspect the impact of direct and indirect corrective feedbacks on the writing ability of EFL learners when using product/process based instructions. To do so, 110 female EFL learners, between the ages of 15 and 18, were randomly assigned into four experimental groups to receive four different kinds of treatments, namely product-based instruction with direc...
