A Green function method is presented which enables computation of laminar flow of an incompressible Newtonian fluid in circular and annular pipes, subject to an arbitrary forcing periodic pressure gradient, in terms of Bessel functions.
In the biosensor, closed circular DNAs can be generated only in the presence of the target DNA, which enables persistent polymerization of template DNA.
For the current studied configuration, a square tube is used for the outer columns, which enables more straightforward fabrication and installation of beam-to-column joints compared with the case of circular outer columns.
The circular buffer approach or Euclidean buffer is the most commonly used one, while the catchment area analysis considers the nature of road network and impedance or barriers which enables a detailed analysis and offers valid and effective results.
In spite of ever-improving remote sensing techniques, which enable almost anyone to search for circular features on Earth's surface, fewer and fewer true craters are turning up, he says.
Nicking of circular DNA resulted in a specific peak, which enabled investigation of the DNA enzymatic cleavage.
These swimmers have a streamlined body, circular body cross section, narrow caudal peduncle, and caudal fin with a high aspect ratio, which enable them to swim fast and efficiently [3] [5].
However, most vehicles have circular headlamps, which emit a circular beam of light at night.
In the moonlight, the lawn, which was circular, looked like an iced-over pond.
