Heinz-Gerhard Franck,Jürgen Walter Stadelhoferand special effects in the aim of finding a specific motion. From the kinematic chain model, the human motion capture data is transformed to a spatial-temporal invariance representation called the motion feature representation, in which each segment of kinematic chain model is represented by an angl

Production and uses of toluene derivatives,ond. From an industrial point of view the most important electrophilic substitutions are nitration and chlorination; among the side-chain reactions oxidation and chlorination are of large industrial significance. Cleavage of the bond between the methyl group and the aromatic ring of toluene occurs d

,Alkylnaphthalenes and other bicyclic aromatics — production and uses,phthylene. Like the methylnaphthalenes, they are present in varying concentrations in coal tar. Where the concentration is sufficiently high, as is the case for methylnaphthalenes and acenaphthene (or acenaphthylene), then they are recovered from coal tar; for compounds present in low concentrations
