WebTransformational reconstruction is a pioneering pattern-making method by Shingo Sato, a Japanese designer, who manipulates pattern pieces in 3D rather than 2D. In this method, pattern cutting is combined with the design process as desired design lines are drawn on a readily test-fitted toile on a dress form to make the pattern. WebFeb 3, 2003 · Inductively coupled plasma-mass spectrometry (ICP-MS) is widely used in for the determination of rare earth elements (REE) in geological samples.
