The seeds, cumulative-dissipative structures.
The results of the paradoxical procedure (experiment E), intended to increase the germination capacity of the seeds, is the proof that the seeds are cumulative-dissipative structures.
It is called a paradoxical procedure because it first generates disorder, in order to eventually facilitate the restoration of order.
The cumulative-dissipative cycle in seeds.
The cycle aimed at keeping the seeds germinating over time takes place in two phases, with the combined action of the “force d” and energy in the form of heat.
At first, the seeds increase their angular velocity relative to other matter, while at the same time they accumulate heat.
Later, the seeds decrease their angular velocity relative to other matter, while at the same time they dissipate heat.
Cumulative phase (borrowed energy).
During the cumulative phase, towards disorder, energy in the form of heat is borrowed. This would increase the configurational energy of the fatty acid molecules in the seeds.
The cumulative processes would be performed in several successive episodes, at different critical values of angular velocity. The molecules would thus tend to differentiate from each other, on many levels of configurational energy. This creates a condition of disorder, of chaos.
The fatty acids of the seeds decrease their fluidity; the seeds decrease their germination power.
Dissipative phase.
According to my interpretation of the experiments, the execution of the dissipative processes is easier and more ready than the execution of the cumulative ones. Moreover, the result is more stable.
So, during the subsequent dissipative phase, the "force d" would uniform the molecular configurations of the fatty acids of the seeds, on a few reduced energy levels, in a kind of reset, a self-organization.
This would happen in the course of a few valid episodes of interaction of the dissipative phase, in accordance with a few critical values of angular velocity relative to other matter.
Energy returned.
The new molecular configurations require less energy. What results in excess is returned, in the form of heat, by dissipation towards the outside, contextually.
In other words, the configuration energy of the fatty acid molecules of the seeds is transformed into energy in the form of heat, and then returned to the environment by dissipation.
Eventually, the fatty acids from the seeds become more fluid because they are more uniform in their molecular configurations. While the germination capacity of the seeds is increased.
Degree of efficiency.
In a seed, this self-organization is all the more effective the greater the percentage of molecules involved in the dissipation process, and the fewer the critical angular velocities that allow the dissipative phase.
Decreased entropy, without decreasing the available energy.
In short, at the end of the two opposite processes, there is a decrease in entropy, with reformation of a previous order, without consumption of energy.
Wanting to express this with an image, it is as if a building, deteriorated due to the passage of time, was decomposed into the bricks, before rebuilding it from scratch with the same bricks, with no energy degradation, because done thanks to a consequent force.
Aknowledgement.
For several of my propositions on this site, I am indebted to what was expressed by I. Prigogine et al., on the “dissipative structures”, and on the phenomena which would take place, starting from conditions far from equilibrium.
