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. It is possible to analyze samples of widely different chemical and mineralogical compositions without the need for preliminary separation or pre-concentration of REE. fbss medical meaning
