In the bronchial tree, cilia beat in unison in one direction, moving substances up and out of the airways.
The authors introduce a principle of active system control and safety - an approach that explains what a model of a system should have, making computer systems more efficient, a crucial new concern in application domains such as safety critical, embedded and low-power autonomous systems like transport, healthcare, and other dynamic systems with moving substances and elements.
The Y. pseudotuberculosis genome appears to be equipped with many extra tools for moving substances in and out of its cell compared to the Y. enterocolitica genome, which appears more streamlined and likely to have adapted to another ecological niche, such as swine tonsils and gut, where variety in substrate transportation is not required.
Like other animals with thick body walls, they use fluid circulation rather than diffusion to move substances through their bodies.
The fluid in the rhynchocoel moves substances to and from the proboscis, and functions as a fluid skeleton in everting the proboscis and in burrowing.
Although GLUT-5 depends on a concentration gradient to move substances across the epithelium and is specific for fructose, GLUT-2 will actively transport glucose, fructose, and galactose (Gibson et al., 2007).
Furthermore, he derived as a theoretical consequence (verified experimentally in mid-century by Armand-Hippolyte-Louis Fizeau) that the ether was partially, and only partially, dragged along by a moving transparent substance depending on the index of refraction of the substance.
Moving to substance now, what qualifies as significant enough to correct?
They've moved away from old badge brands, but they're moving toward substance and technology.
