Th. age at wh.ch.a woman enters natural menopause h.s also been associated to death.from any cause. menopause is a natural component of aging th.t h.ppens between th. ages of 45 and 55, with.th. average menopausal age being 51. Previous research.h.s revealed th. age at wh.ch.women reach.menopause, but th.re is no evidence to support th. link between menopause and longevity. We made a study in assessing th. limits of maximum lifespan at menopausal age in our previous article. In th.s paper, we aim to predict th. maximum lifespan of women at mean menopausal age.

h.lf-h.usler compounds are an impressive class of materials with.a h.ge potential for different applications such.as in future energy, especially in th. fields of th.rmoelectrics and solar cells. We present ab fnitio total energy calculations with.n th. modified Becke-Joh.son generalized gradient approximation （mBJ-GGA） to obtain th. ph.sical properties of srAlGa compounds. Th. structural, elastic, acoustic, electronic, ch.mical bonding, optical, and th.rmoelectric properties are calculated and compared with.th. available calculation data. Th. srAlGa is found to be a small-band-gap （0.125-0.175 eV） material, suitable for th.rmoelectric applications with.a relatively h.gh.seebeck coefficient. Also, srAIGa h.s th. potential in th. optoelectronic applications due to h.gh.optical conductivity and reflectivity in th. infrared and visible region of electromagnetic spectra.
