One in every 5 children in the U.S. develops anemia at some point during childhood, according to the authors of a June 2010 article published in American Family Physician. While there are many causes of childhood anemia, some common signs and symptoms are prevalent in children affected by the condition. If your child has signs or symptoms suggestive of anemia, schedule an appointment with your doctor for testing and appropriate treatment.
Semi in Latin means half. Semicircle by itself means half circle. In Geometry, semicircle can be defined as a 2-dimensional figure that forms half of a circle is called Semicircle. It is a closed shape that is half a circle but diameter of that circle. Which means the diameter of a circle cuts the circle into two equal semicircles.

The semimajor axis runs from the center to the ellipseâs edge through a focus. It is that measure of the orbitâs radius at its most distant points. In the case of a circle, it then becomes the radius itself. We can think of it as any ellipseâs long radius. In the world of astronomy, the semimajor axis is known to be part of an orbit. For objects within the solar system, this axis is directly related to the orbital periods, which is noted in Keplerâs third law.
