ould be activated (joined in) (the 3rd micro cycle). The operating time of the SFU response/operation depends on the speed of utilization of energy spent for the SFU performance, for example, the speed of reduction of sarcomere in a muscular cell which is determined by speed of biochemical reactions in the muscular cell. After that all SFU terminate their function (the 4th micro cycle). At that, the SFU spends its entire energy it had and could use to perform this action. As far as the sequence of actions and result of action would always be the same, the measure of energy would always be the same as well (energy quantum). In order for the SFU to be able to perform a new action it needs to be "recharged". It may also take some time (the time of charging). The way it happens is discussed in the section devoted to passive and active systems (see below). Any SFU's performance cycle consists of these micro cycles. Therefore, its operating cycle time would always be the same and equal to the sum of these micro cycles. Once SFU started its actions, it would not stop until it has accomplished its full cycle. This is the reason of uncontrollability of any SFU in the course of their performance (absolute adiaphoria), whereby the external influence may quickly finish and resume, but it would not stop and react to the new external influence until the SFU has finished its performance. In real composite SFU these micro cycles may be supplemented by micro cycles caused by imperfection of real objects, for example, non-synchronism of the executive elements 'operation due to their dissimilarity. Hence, it follows that even the elementary systems represented by SFU do not react/operate immediately and they need some time to produce the result of action. It is this fact that explains the inertness/lag effect/of systems which can be measured by using the time constant parameter. But generally speaking it is not inertness/lag effect /, but rater a transitory (intermittent) inertness of an object (adiaphoria), its inability to respond to the external influence at certain phases of its performance. True inertness is explained by independence of the result of action of the system which produced this result (See below). Time constant is the time between the onset of external influence and readiness for a new external influence after the achievement of the result of action. The analogues of composite SFU are all objects which operate similarly to avalanche. The "domino principle" works in such cases. One impact brings about the downfall of the whole. However, the number of downfalls would be equal to the number of SFU. Pushing one domino dice will cause its drop resulting just in one click. Pushing a row of domino dices will result in as many clicks as is the number of dices in the row. Biological analogues of composite SFU are, for example, functional ventilation units (FVU), each of which consisting of large group (several hundred) of alveol...
