A shielded electrical cable is disclosed. When the inhaler is not in use, the closure element prevents moisture and dirt from entering the sensitive parts of the device. The method can also include automatically identifying one or more charter transports having an available passenger accommodation. The conductive structures may also be used to control a threshold voltage for a logic device. Each winding is formed by a near-core low-voltage winding, which are each wound by an associated high-voltage winding, and the discharges of the low-voltage windings are axially designed, so that the lateral spacing of the windings to each other is minimized. The pharmaceutical formulation contains peroxidic species or reaction products resulting from oxidation of an alkene, such as geraniol, by an oxygen-containing oxidizing agent, such as ozone; a penetrating solvent, such as dimethyl sulfoxide; a dye containing a chelated metal, such as hematoporphyrin; and an aromatic redox compound, such as benzoquinone.
