    Abstract: In this study, an investigation is made into the effects of thermophoresis and viscous dissipation on chemically steady hydromagnetic free convective boundary layer flow in a porous media. A mathematical model was designed to govern the flow used in the study of the effects of chemical reaction, magnetic field, viscous dissipation, and thermophores... Show More

    Abstract: Physical distribution (transportation) of goods and services from multiple supply centers to multiple demand centers is an important application of linear programming (LP). A transportation problem (TP) can also be solved using the simplex method when expressed as an LP model. However, because a TP has a large number of variables and constraints, s... Show More
