A means of measuring and monitoring skeletal growth rate using a plasma analyte, amino-terminal C-type natriuretic peptide. The position of the rotation center is determined on the basis of centrifugal accelerations imparted to the measuring position when the jig is placed at three different positions and eccentricities of the measuring position from the rotation center when the jig is placed at the three different positions. Services securely accessed by the litigation management component can be based, at least in part, upon a subscription level, a client identifier, a user identifier andor a group identifier. The result is that substantially none of the spacers create overlapping dead spots in a composite image. Also disclosed are a composition for forming a quantum dot-containing pattern, where the composition includes the photosensitive quantum dot, and a method of forming a quantum dot-containing pattern using the composition.
