This study analyzes the consequences of first-order chemical reactions. radiation. and viscous dissipation on the unsteady magnetohydrodynamic natural convective flow of a viscous incompressible fluid over a vertically positioned semi-boundless oscillating plate with uniform mass diffusion and temperature. An implicit finite-difference technique is employed to solve a set of dimension... https://halohealthcarers.shop/product-category/tens-ems-units/
