Typical conventional database security scheme mechanisms are integrated in either the application or database. In this system, a storage apparatus includes a processing unit for de-duplicating a plurality of files having the same content regarding a file group of data inputtedoutputted through a host apparatus. A supply end of the conduit assembly is positioned at the base unit and is connected to a supply line for uncured concrete or other material, while a dispensing end of the conduit assembly is supported by the movable support and extends outwardly therefrom to dispense uncured concrete or other material through a discharge outlet. The information is thereafter downloaded from the central database to the wireless device, where it is permanently stored. Based on this method, it is possible to reliably form composite metal oxide nanomaterials over a wide range of compositions. Each of the screen-printed includes at least one of a passive device and an active device.
