The input shaft turns continuously, and each pin's position is controlled by the engagement of an individual clutch.
To avoid any sedimentation effects a magnetic stirrer is turning continuously throughout the whole experiment.
"However, if we have a light bulb which has been left turned on continuously, turning it off can be a good signal, too".
In most experiments, the lights were turned on continuously and volunteers had no control over the light-dark cycle (except by closing their eyes during sleep).
Physiologically, HA is turned over continuously (Laurent and Fraser, 1992), in a process in which initial intermediate-sized fragments produced extracellularly are internalised and further degraded (Stern, 2003).
For example, intestinal epithelia are turned over continuously and replenished by proliferation of stem cells located close to the base of crypts.
When the initiation stimulus was pecked, one (no-choice trial) or two (choice trial) test stimuli started to flash (0.3 s on, 0.7 s off; always outer keys); as soon as the bird pecked, the chosen light was turned on continuously, while the other stimulus was turned off (only applicable during choice trials) and the stimulus-related delay (fixed/variable) started.
To examine the various responses, we consider the effect of both signals being turned on continuously at a high level (which we denote in the in Table 3 as a green square), the result of one of the factors occurring at a high level whilst the other is either low (denoted by a yellow square) or off (denoted by red).
The host in turn continuously deploys an array of innate and acquired cellular and humoral defences to prevent pneumococci from breaching tissue barriers.
Research subjects can be presented with specific projects and information and, in turn, continuously tailor their consent preferences according to their desires and needse.
