Abstract: The invention is directed to a process for dehydrating and recycling back into a BOF converter wet BOF scrubber sludge to produce a steelmaking revert having an improved flow rate when handled in a recycle stream. Wet sludge is combined with hot BOF slag to provide a slag/sludge mixture. The wet sludge causes the mixture to have a moisture content greater than 10% water by weight, and the hot slag, having a temperature below the molten liquid state, vaporizes the water in the mixture and reduces the moisture content to about 4% water by weight or less. The dehydrated mixture has improved flow rate properties when it is recycled as a steelmaking revert.

Abstract: A carrier for immobilizing lipase is prepared by bonding a silane coupling agent having a carboxylic-ester group to an inorganic carrier. Preferred silane coupling agents are .gamma.-methacryl oxypropyltrimethoxy silane, .gamma.-acetoxypropyltrimethoxy silane or .gamma.-acryloxypropyltrimethoxy silane. The inorganic carrier can be kaolinite, porous glass, bentonite, silica gel, alumina, silica, silica-alumina hydroxy apatite or calcium phosphate gel. Lipase is immobilized by mixing lipase with the inorganic carrier containing the bound silane coupling agent, filtering the resultant mixture and drying the filtered mixture. Functional groups of the lipase are bonded to the carboxylic-ester group of the silane coupling agent.

Abstract: A program designing method which makes it possible to efficiently design an application-oriented program without errors irrespective of levels of technical skills of engineers. In this program designing method, all types of definition items which are processed by a processing system for specific business use are extracted. Program segments (ASL) with a single function are generated in a form in which a corresponding definition item is used as a keyword and ASLs are control-independent of each other in such a way that each definition item is associated with one ASL. A control program (FAL) is separately generated which combines ASLs with each other in an organic manner by operating and controlling the group of ASLs. Each necessary ASL is activated by use of an array of a plurality of link statements included in FAL, and a source program which satisfies required business processing functions is produced by merging FAL and ASL into one.
