If you have a blood ketone meter, this is what the readings mean: 1  Light Ketosis: 0.5 mmol/L â 0.8 mmol/L. 2  Medium Ketosis: 0.9 mmol/L â 1.4 mmol/L. 3  Deep Ketosis (best for weight loss): 1.5 mmol/L â 3.0 mmol/ L.
(3) Symmetry, in the general sense, means the invariance of the structure of a mathematical or physical object with respect to transformations of the object. For example, the symmetry of the laws of the theory of relativity is determined by their invariance with respect to the Lorentz transformations.1) A symmetry, in the narrow sense, is a reflection with respect to a plane Î± in space or with respect to a line a in the plane. Such a symmetry is a transformation of space or the plane that takes every point M into a point Mâ such that the line segment MMâ is perpendicular to Î± or a and is divided in half by Î± or a.
Reflection symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection.That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2D there is a line of symmetry, in 3D a plane of symmetry.nother way to think about the symmetric function is that if the shape were to be folded in half over the axis, the two halves would be identical: the two halves are each other's mirror images. Thus a square has four axes of symmetry, because there are four different ways to fold it and have the edges all match.
