Van der Aa, like Fure, uses technology to get at something elemental: for him, the long reach of memory; for her, the irreversibility of change.
The presence of structural changes in radiographs correlates with poor function, and is associated with irreversibility of changes.
There's more than a hint of the controversialist in his work, and it seems an unlikely coincidence that Lovelock became convinced of the irreversibility of climate change in 2004, at the very point when the international consensus was coming round to the need for urgent action.
It highlights the role of water-soil/sediment interactions, acid-neutralizing and buffering mechanisms, and the irreversibility of some changes during the drying and wetting of sub-aqueous wetland soils.
In this paper we develop an analytical and graphical formulation of the constructal law of maximization of flow access in systems with heat and fluid flow irreversibilities and freedom to change configuration.
In view of the large variation for the obtained ΔCp (between 3.2 and 10.1 ± 0.8 kJ/(mol K)), it is evident that: (1) the sensitivity of different approaches to the structural changes; (2) irreversibility of unfolding; (3) non-ideal two-state unfolding behaviour need to be considered prior to interpretation.
To clarify our arguments, we have gone over the whole section in question ("Mutational epistasis underlies genotypic irreversibility") and made significant changes.
Spatial distribution of spacers such as hemicellulose and lignin can limit the degree of irreversibility of the structural changes caused by drying [ 18, 27, 44].
In transformation processes, subsequent mechanisms, which are not included in the model description, are in place to ensure irreversibility once the switch changed its qualitative state from the initial condition.
With dwindling evidence for the law-like nature of Dollo's Law, we anticipate a return to Dollo's original focus on irreversibility of all kinds of changes, not exclusively losses.
