A display device includes pixels disposed in a matrix on a transparent base plate. The compositions include a quickly resorbable porous carrier, a more slowly resorbed mineral scaffold and an osteogenic factor, preferably a bone morphogenetic protein. The spline is mechanically attached or fused to the coupling. The memory module and processing module in combination are operable to execute instructions that detect the geometry associated with the hard disk drive. Said virus is replication-deficient in cells which do not contain YB-1 in the core and codes for an oncogene or oncogene product, especially an oncogene protein, which transactivates at least one viral gene, preferably an adenoviral gene, said gene being selected among the group comprising E1B55kDa, E4orf6, E4orf3, and E3ADP.
