Abstract: A user may select one or more potential common ancestors with a DNA match to view the target individual's relationship with them. The process may include identifying, from a first genealogical profile of the target individual. A first individual has a first linkage that connects the target individual towards the selected potential common ancestor. The process may also include identifying, from a second genealogical profile of the DNA match, a second individual who has a second linkage that connects the DNA match towards the selected potential common ancestor. The process may further include connecting the first linkage and the second linkage with the selected potential common ancestor by adding one or more individuals whose profiles are retrieved from other searchable genealogical profiles stored in the online system. With the nodes and connections available, the process may generate a map of visual connections between the target individual and the DNA match.

Abstract: An inflatable wand for positioning within an upward oriented, mining borehole and near a lower collar opening thereof wherein the wand provides a conduit for introducing and retaining liquid explosive materials within the borehole. The wand includes a flexible tube with longitudinally oriented reinforcing fibers embedded in an elastic composition such as rubber. The tube is constructed to permit radial elongation in response to a force arising within the tube and directed radially outward, but to restrain against axial elongation during use. Such radial elongation arises because of back pressure developed by the flowing explosive as it is impeded at a valve outlet at the distal end of the wand. Enlargement of the wand seals the opening of the borehole without destruction of the elastic material on sharp points and edges of the borehole collar.
