  This paper investigates the beta decay of nuclei within the sd model space,
encompassing the $0d_{3/2}$, $0d_{5/2}$, and $1s_{1/2}$ shells. We
comprehensively analyze their decay characteristics, including the half-life,
$logft$ value, Q value, branching ratio, B(GT) value, M(GT), and R(GT) value.
These results are compared with experimental data from Z = 8-19 nuclei,
employing the nuclear shell model framework. The calculations are performed
using the USDB\cite{usdb} interaction, which is well-suited for nuclei with
active valence nucleons in the $0d_{3/2}$, $0d_{5/2}$, and $1s_{1/2}$ shells.
The study offers valuable insights into the beta decay properties of these
nuclei and contributes to our understanding of the nuclear shell structure.}
