She was sitting in a "W" position, knees, shins, ankles, feet and butt on the floor. Hypermobile EDS (hEDS) and hypermobility spectrum disorder (HSD) is by far the most common type; these conditions are part of a spectrum and the distinction is hoped to be useful for research, but is otherwise academic. Dispersive Spectroscopy (EDS) Analysis provides qualitative elemental (Be to Cf) and chemical microanalysis. Adapted from [2] As discussed on page4650 , X-ray absorption is a function of the energy of X-rays. Interaction of an electron beam with a sample target produces a variety of emissions, including x-rays.
