a study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
The Different Mechanisms of Action Potential Propagation in the Heart
It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...

متن کاملAction potential propagation in a thick strand of cardiac muscle.
A theoretical model of action potential propagation in a thick strand of cardiac muscle is presented. The calculation takes into account the anisotropic and syncytial properties of the tissue, the presence of the interstitial space, the effect of the surrounding tissue bath, and the variation of the potential both along the strand length and across the strand cross section. The bidomain model i...
متن کاملAction Potential Propagation
In the previous notes, we described the action potential for a “point” cell, so that we could use an ODE model. Here, we consider propagation of the action potential along an axon. Consider a system in which the intracellular and extracellular spaces are separated by a cell membrane. Let x be the one-dimensional spatial coordinate, and consider current conservation in the intracellular region c...
