More than 13 years later, a very similar phenomenon was described in The Lancet, this time dubbed ‘PlayStation 2 (PS2) Thumb’ [5]; PS2 thumb was later described in ‘epidemic’ proportions in The South African Medical Journal [6] Confusingly, the term ‘Nintendinitis’ (compared to ‘Nintendonitis’) was also coined in 1990 to describe a repetitive strain-type injury affecting the wrist and elbow [7]. 
Design The materials preferred for this design are regular polymers.

Experimental Materials.
· From the experimental study it can be suggested that, the flax and glass fiber composite materials can be used as an alternate materials for conventional fiber reinforced polymer composites.

However traditional activated carbons still consider non-renewable and expensive materials such as coal, timber and so on[4].With the development of industrial technology, any carbonaceous materials, rich in cellulose and lignin,are theoretically feasible for activated carbons production [5].
Experimental Materials.
From the results above, we considered the deproteinization vinasse as the materials of activated carbon preparation.
