The invention relates to an aqueous, chromium-free and curable corrosion protection agent for the first coating of metal surfaces, said agent containing at least one organic polymer or copolymer of at least partially acylated vinyl amines, for improving the properties of adhesion of the cured first coating to the metallic surface and to further organic coatings. In one illustrative embodiment, the fluid delivery device may include an electro-osmotic pump having an anion exchange membrane and a cation exchange membrane in the same device. The chemiluminescent device comprises a transparent or translucent housing and a chemiluminescent drug storing device with protection casing, the housing is a deformable and sealed housing and has a cavity inside, and the chemiluminescent drugs storing device is provided in the cavity. In another embodiment, a vibrational or mechanical input together with a biochemical compound enhances both bone fracture healing and treats osteoporosis.
