let $f_q d_{2n}$ be the group algebra of $d_{2n}$, the dihedral group of order $2n$ over $f_q=gf(q)$. in this paper, we establish the structure of $u(f_{2^k}d_{2n})$, the unit group of $f_{2^k}d_{2n}$ and that of its normalized unitary subgroup $v_*(f_{2^k}d_{2n})$ with respect to canonical involution $*$ when $n$ is odd.

conclusions the findings of the present study well demonstrated that the p. aeruginosa biofilm-producing isolates were more resistant to the tested antibiotics. furthermore, because of wide distribution, it seems that the psla gene is associated with biofilm formation. results biofilm formation was observed in 70% of the p. aeruginosa isolates. the potential formation of biofilm was significant...
