This test is divided into five stages that are characterized by increasingly complex chains of responses.
While learning the first task, the fixed consecutive number schedule, rats pressed mainly the left lever, while the right one was only used to terminate the chains of responses.
There's no individual emergency planning officers in Baker's two district councils, but the county council runs a joint emergency planning unit and when there are crises such as a major flood, there's a clear chain of response that links up all the different agencies involved.
After an injury, a chain of responses takes place in the spine: broken blood vessels swell, killing off neurons that end up squeezed within the cage of the vertebrae.
That principle sets off a chain of responses suggested by reason and history: if accepting Trump's leadership is the democratic way, then any American patriot should line up behind him.
A question, together with its chain of responses in chronological order, constitutes a complete system interaction.
These collective and individual adaptations may take a long time to manifest themselves, both because of in-built latencies within the system (e.g. the lag between exposure and expression of a health outcome), and because the initial perturbation may trigger a long chain reaction of response as the effects spread out through the wider system.
Furthermore, the phase miscibility between HDPE and LLDPE was found to increase with increasing HDPE molecular weight, which would affect the sensitivity of molecular chains for response to external shear.
Recent experiences with large-scale disasters have strongly reinforced the fact that hospital capacity is the major rate-limiting factor in the chain of medical response.
