A graft harness for securing a ligament in a bone tunnel takes the form of a shaped plug having a proximal end and a distal end. Methods for forming the bonded cellulosic fibrous product and personal care absorbent products that include the bonded product are also provided. Two separators are mounted together and preferably mounted to the raceway sidewall, forming at least a base passage between the separator and the sidewall of the raceway, and an elevated passage between the walls of the separators. The present air mattress is not only lightweight and flat but also has a simple structure so as to be suited to automated production, thereby reducing productions costs. The method may include contacting the carbon nanotubes with a solution containing chondroitin sulfate cation salt of formula wherein R1 is MSO3 and R2 is H, or R1 is H and R2 is MSO3; M is an alkaline metal, or an alkaline earth metal further bound to a monovalent counter-anion; n is at least 20. A gate electrode is formed on the semiconductor substrate via a gate oxide film.
