Radius definition: a straight line extending from the center of a circle or sphere to the circumference or surface. See examples of RADIUS used in a sentence.
where the correction factor in the denominator c is now included since the scaling factor 6 is only applicable for molecules or complexes that are significantly larger than the solvent molecules surrounding the particle, falling to around 4 when these become comparable. It has been suggested that ...
Disclosed is a configuration of an autonomous vehicle for autonomously following a moving subject based on a radius of a virtual sphere surrounding the autonomous vehicle. The autonomous vehicle may be an unmanned ground vehicle or an unmanned aerial vehicle, which autonomously follows the subject (e...
Fortunately the condition is not too serious at this stage since there remains a considerable bulk of elastic material surrounding the yielded area which contains the resulting strains within reasonable limits. As the pressure is increased further, however, plastic penetration takes place deeper and ...

Around 5.4Â billion years from now, the core of the Sun will become hot enough to trigger hydrogen fusion in its surrounding shell.[107] This will cause the outer layers of the star to expand greatly, and the star will enter a phase of its life in which it is called a red giant ...
