Evolution in natural populations is driven by a dynamic interaction between multiple biotic and abiotic factors including continuous competition within and between species (Valen 1973).
In Europe, no one ever succeeds in unifying it, and you have continuous competition.
Continuous competition in this marketplace imposes "Is it worth it?" tests for the unhappily overweight.
"In our industry, there is substantial and continuous competition for highly-skilled business, product development, technical and other personnel". .
Inspired by these insights, Shu et al. proposed a new model, termed the "seesaw" model, in which the pluripotent state has a precarious balancing equilibrium that results from continuous mutual competition between rival lineage specification forces.
They exemplify that whereas it may take several days for kinetic steady states to be obtained experimentally, once spread sheets have been set up, competition between species in a continuous flow chemostat may be modelled in a matter of seconds.
The results may conveniently be presented in the form of continuous cooling transformation (CCT) diagrams to show the competition between the different variables involved.
The causes of the continuous "low-level" extinction events, which form the majority of extinctions, may be the result of competition between species for limited resources (the competitive exclusion principle).
Multiple twinning systems can be activated in the same grain, and the competition between them favors those capable of producing continuous deformation across the grain boundary.
When performed under continuous cooling conditions, the simulations give an insight into the competition between nucleation and early growth, which determines the variation of ferrite grain size with the cooling rate and with austenite grain size.
