Some embodiments of a method and an apparatus to provide interoperability between different digital content protection schemes have been presented. An embodiment is a method for forming a semiconductor structure. Traffic policy parameters are established for traffic-classes and the policy is implemented at each individual policer. Fructose is converted to 5-hydroxylmethylfurfural in the presence of metal halide and acid catalysts. The second trace may be associated with a position within a predetermined radius from a position associated with the first UV. Such a method is useful for producing large quantities of biofilament material.
