Abstract: To provide a fastening method and a fastening device for a self-piercing rivet so that the adhesive force of the adhesive applied between the members to be fastened can be exerted to a greater degree, a rivet fastening method comprises a step of preparing at least two plates stacked via an adhesive layer; a step of preparing a rod-shaped punch having at least two openings and an air flow path through which the at least two openings are communicated; a step of preparing a self-piercing rivet with a through hole; and a step of driving the self-piercing rivet into the at least two plates with the punch so that one of the at least two openings in the punch faces the through hole of the self-piercing rivet.

Abstract: The present invention provides a composition for promoting cell proliferation containing polylysine in which at least one amino group is mono-substituted by dicarboxylic acid.

Abstract: A vehicle management apparatus includes: a vehicle information acquirer acquiring a position of a vehicle designated as a delivery destination of a package; a condition acquirer acquiring an instruction from a recipient of the package, or a reception condition including an action schedule of the recipient; and a determination section determining, based on the reception condition, whether the vehicle that has the package delivered is to be moved from the position acquired by the vehicle information acquirer.

Abstract: Cultivating a pluripotent stem cell in a medium comprising at least one member selected from the group consisting of ethanolamine, an ethanolamine analog, and a pharmaceutically acceptable salt thereof, and which is substantially free of ?-mercaptoethanol or contains ?-mercaptoethanol at a concentration of not more than 9 ?M, and the like, is effective for the proliferation of a pluripotent stem cell while maintaining an undifferentiated state.

Abstract: A medium which comprises a fibroblast growth factor (FGF), and a sulfated compound or a pharmaceutically acceptable salt thereof at a concentration which promotes the growth of a stem cell in the presence of FGF, is useful for culturing stem cells.

Abstract: Cultivating a pluripotent stem cell in a medium comprising at least one member selected from the group consisting of ethanolamine, an ethanolamine analog, and a pharmaceutically acceptable salt thereof, and which is substantially free of ?-mercaptoethanol or contains ?-mercaptoethanol at a concentration of not more than 9 ?M, and the like, is effective for the proliferation of a pluripotent stem cell while maintaining an undifferentiated state.

Abstract: Culture media which contain a water-soluble polymer, such as polyvinyl alcohol and the like, and albumin, and the like, are useful for the proliferation of stem cells, and show good culture results, particularly with iPS cells, and maintain the stability of the medium properties, as well as using a reduced amount of albumin.

Abstract: A high proof stress aluminum alloy extrusion material having superior bendability and crack resistance. The high proof stress aluminum alloy extrusion material is an aluminum alloy comprising: 5.0 to 7.0 wt % of zinc; 0.5 to 1.5 wt % of magnesium; 0.05 to 0.3 wt % of copper; no greater than 0.15 wt % of zirconium; 0.1 to 0.4 wt % of iron; 0.05 to 0.4 wt % of silicon; with the balance being Al and impurities, in which at least 90% of a metallographic structure is a recrystallized structure.

Abstract: A technique for efficiently culturing cells such as stem cells is provided. Cells such as stem cells are cultured using a cell culture vessel coated with a fibroin-like protein into which a cell adhesion sequence containing RGD (Arg-Gly-Asp) is inserted.

Abstract: A medium which comprises a fibroblast growth factor (FGF), and a sulfated compound or a pharmaceutically acceptable salt thereof at a concentration which promotes the growth of a stem cell in the presence of FGF, is useful for culturing stem cells.
