review text: Summary: The study sought to investigate the influence of a magnetic field on heat and mass transfer by mixed convection from vertical surfaces in the presence of Hall, radiation, Soret (thermal-diffusion), and Dufour (diffusion-thermo) effects. The similarity solutions were obtained using suitable transformations. The similarity ordinary differential equations were then solved by \texttt{MATLAB} routine \texttt{bvp4c}. The numerical results for some special cases were compared with the exact solution and those obtained by \textit{N. S. Elgazery} [Commun. Nonlinear Sci. Numer. Simul. 14, No. 4, 1267-1283 (2009)] and were found to be in good agreement. A parametric study illustrating the influence of the magnetic strength, Hall current, Dufour, and Soret, Eckert number, thermal radiation, and permeability parameter on the velocity, temperature, and concentration was investigated.
