A magnetic memory includes magnetic memory elements corresponding to magnetic memory cells and at least one shift register. A directional thrust steering mechanism having a pair of vertical rudder blades positioned on either side of a conventional propeller extending from the centerline of the lower hull directs the water from the propeller, thus enabling the vessel to move more efficiently and with greater maneuverability in both forward and reverse directions. Flushing strips with male protrusions are installed in female slots in between channel beams. The apparatus provides a plurality of fluid permeable channels formed within the sand screen, which are disposed along the entire length of the screen. The oversized slot creates sufficient clearance for removal of a three-dimensional airfoil, while the sleeve creates a sufficiently tight fit to allow the pieces to be brazed together. This invention thus relates to the seeds of soybean variety XB31H07, to the plants of soybean XB31H07 to plant parts of soybean variety XB31H07 and to methods for producing a soybean plant produced by crossing plants of the soybean variety XB31H07 with another soybean plant, using XB31H07 as either the male or the female parent.
