Title: Dna base mismatch detection using flow cytometry
Inventor: CAI HONG
IPC: C12Q1/6862
Filed: 1998-10-28
Abstract: Flow cytometric DNA base mismatch detection. The use of immobilized mismatch-binding protein-coated microspheres to bind fluorescently labeled, mismatch-containing DNA for detection by flow cytometry is described. The genomic DNA  of interest is made fluorescent by one of a number of techniques. The resulting fluorescent DNA is melted and allowed to reanneal. If the genomic sample contains a polymorphic site, the reannealed DNA will contain base mismatches. Microspheres bearing immobilized mismatch-binding protein are added to the DNA samples and the mismatch-containing DNA allowed to bind to the mismatch-binding proteins. The sample is then analyzed by flow cytometry to detect the fluorescent DNA bound to the microspheres. The present flow-cytometric method for mutation scanning has several important features: it is a single step, no wash assay, capable of rapid and sensitive analysis. It will allow amplified regions to be rapidly scanned for the presence of polymorphisms to prioritize samples for complete sequencing or to detect mutations in known regions of the genome.

Title: Ground compacting device
Inventor: BLANCKE UWE
IPC: E02D3/026
Filed: 2000-08-25
Abstract: The invention concerns a device for ground compacting, having at least one vibrating roller whose casing surface is composed of a plurality of segments in peripheral direction, at least some of which having a radius of curvature that deviates from the mean radius of the roller. In order to smooth the jolting movement resulting from the shape of the rollers in devices of this type, it is proposed to construct the tire casing of the roller from several sections lying adjacent to one another in axial direction, said sections having segments abutting one another in peripheral direction, whereby the abutting edges are displaced vis-à-vis one another in peripheral direction. The advantage of these rollers is that their "rolling behaviour" is improved considerably.

IPC: G06F17/30
Filed: 2000-11-24
Abstract: A database deletion tool that is configurable, extensible and adaptable to the changing structure of a database to provide a desired deletion. Embodiments of the invention are configurable in the tasks performed, extensible to new tables and changes to the database as the database develops, and adaptable in changes to the database structure (or schema) without requiring customization (i.e., through custom programming).  Embodiments of the invention are programmed to identify the data delete rules associated with data to be deleted. Based on the rules identified, some embodiments will perform a top-down or bottom up deletion of data in the database. Top down deletion uses cascade operations (e.g., cascade delete) in the database. During a bottom up deletion, the tables affected by the cleanup may be recursively determined using metadata stored by the database system. An algorithm also determines the referential integrity constraints that affect the data requiring deletion. From this information, embodiments of the invention identify all the child tables affected, identify the data in the child tables that require deletion and then, from the bottom child tables up to the parent tables affected, delete the data required. In some embodiments, the database delete tool acts as a database cleanup tool which removes unwanted data from a database.
