The present invention is a method for forming super steep doping profiles in MOS transistor structures. The games board includes a flexible sheet and a support structure for holding the sheet. The present invention also provides kits and methods for treating inflammation, pain and fever; for treating andor improving the gastrointestinal properties of COX-2 inhibitors; for facilitating wound healing; for treating andor preventing renal toxicity; and for treating andor preventing other disorders resulting from elevated levels of cyclooxygenase-2. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The method for removing unreacted monomers in polymer using SCC according to the present invention may control polymer residence time and thus does not lower polymer stability even under high temperature condition, and has high area density and thus has excellent unreacted monomer removal efficiency without using steam and the like, or with a small amount of steam, and the like. Borrowed resources may be reclaimed and transferred to the guaranteed status participant.
