A system and method for generating a one-dimensional spatial index and a temporal index in relation to one or more two-dimensional location points of one or more mobile devices to enable near-real-time searching of devices having fast-changing location information is provided for. A motor is provided for the movement of the shift member in the first direction and a spring element is provided for the movement of the shift member in the second direction. The first and second tubular bodies are telescopically movable here relative to each other for leaving clear a radial opening through which the liquid can leave the pouring spout. Laboratory results have demonstrated manganese 2, cobalt 2, vanadium 2 and similar families of catalysts to be effective for oxidative catalytic conversion of primary alcohols to products comprising related aldehydes and glycol ethers, and secondary alcohols to products comprising ketones and related products.
