The origin of plastic relaxation is probably the inclusion of a dislocation network.
Our results are in qualitative agreement with experimental studies and elucidate the microstructural origin of plastic hardening in this class of materials.
Two series of bituminous coals of different rank, geographic origin and plastic properties were subjected to thermal treatment up to 1000 °C in a nitrogen atmosphere at two heating rates (3 and 10 °C min−1), using two thermobalances of different design.
Recent studies have shown that the positional information of early blastema cells of connective tissue origin is plastic, and that these cells can be reprogrammed if grafted to a position on the limb that is different from their position of origin (McCusker and Gardiner, 2013).
The aim of this work is to analyse the origin of phenotypic plastic changes into a biologic structure, in this case the hip.
Thus, some gene clusters (clusters 4, 7) showed either a net difference between origins when reared either in FW or BW or showed an origin effect on plastic response to environmental conditions (clusters 5, 6).
In the particular case of this land fish, the lack of genetic differentiation among populations suggests extensive dispersal among populations and the possibility that population divergences in ornamentation have a plastic origin.
Non-plastic species are best adapted to the conditions existing at the time of their origin (past conditions), while plastic species can adapt to current conditions.
I'm surveying the crowd, wondering how many of these justifiably angry people carry knives or even handguns to express their palpable hostility, and what the ratio of security and police officers is to civilians, when I see a small man of no certain ethnic origin dragging a large plastic garbage bag behind him.
This study revealed both an origin (genetic) and environmental (plastic) effect on growth, and suggested a possible origin-environment interaction.
