Bifurcation/Chaos and Their Practical Relevance to Chemical and Biological Systems

Bifurcation and chaos are important phenomena affecting many physical and chemical systems. they are also related to the stability/instability and multiplicity phenomena associated with these systems. the phenomena are not only of theoretical/mathematical interest but are also important for laboratory, pilot plant and commercial units. this paper concentrates on 3 systems: 1. the novel auto-thermic circulating fluidized membrane steam reformer (cfbmsr) for the efficient production of the clean fuel hydrogen and which shows multiplicity of the steady state (static bifurcation) 2. a novel fermentor for the efficient production of bio-ethanol that shows static/dynamic bifurcation as well as chaotic behaviour 3. the neurocycle of the acetylcholine transmitter in the brain using diffusion-reaction models in order to gain insight into their possible connection to alzheimer and parkinson diseases (ad/pd); these are preliminary efforts to investigate the bifurcation and chaotic behaviour of this neurocycle.
