Abstract: The invention relates to a multi-step method for the selective, environmentally friendly and economical recovery of non-ferrous metals from industrial wastewater. The method is based on the principle of the complexing of the non-ferrous metals, separating out of the complexes and subsequent decomplexing of the non-ferrous metals. Siderophores are used as complexing agents. The siderophores are recovered within the process. The method can be used in particular even in the case of low non-ferrous metal concentrations. The method is efficient, environmentally friendly and economical.

Abstract: Servicing a request for information from a device with limited network, memory, and display resources includes receiving a request for a page of information from a client device. The requested page is retrieved, and points within the page at which the page may be divided into sub-pages are identified. The points at which the page may be divided may be statically defined within the page or dynamically determined from the structure of the page. The page is separated at the identified points into multiple sub-pages, and it is determined if each of the multiple sub-pages may be used by the client device. A sub-page may be used by the client device if a weight of the sub-page, which may be expressly calculated or estimated, is less than a maximum allowable weight. The multiple sub-pages are linked, and the multiple sub-pages are individually transferred to the client device.

Abstract: A location context-aware mobile system determines the location of a mobile device and updates a user interface based on the location of the device. By using the location of the mobile device to reduce the amount of information required to be entered by a user in a business process application, the system increases the feasibility of providing business process applications on mobile devices such as mobile telephones.
