Abstract:
This is an in vitro model to mimic the conditions present during gallstone formation. Adenosine mono-phosphate (AMP), an important bio-molecule, was chosen. Its effect on the formation of periodic/chaotic patterns in the deoxycholate-CuCl2-gel and deoxycholate-CuCl2-glucose-gel systems were studied. FTIR spectroscopy was used to identify the structure of the precipitates. The results indicate that the patterns formed in the systems with AMP are different. And FTIR spectra show that AMP may also be involved in the coordination sphere of Cu2+ ion. The results are more complicated in the deoxycholate-CuCl2 system containing glucose, suggesting that the nonlinear scientific concept should be considered in understanding gallstone formation.

Parallel RLC Circuits
A simplified parallel RLC circuit model with a DC input source generating a step response is employed in this context. When the switch is turned on, Kirchhoff's current law is applied, leading to a second-order differential equation.
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
