How do bacteria find their way to the food ? many biological systems use the chemo-taxis algorithm to improve their conditions and hence, their chance to survive. Chemo-taxis in general refers to movement influenced by chemical properties of the medium. In this model, we have a group of...

The adiabatic catalyst problem arises in the field of chemical engineering. If chemical reaction kinetics within a solid catalyst body are influenced by mass transfer multiple steady states are possible for a certain range of the governing parameters: arrhenius number, prater number and thiele...
