Abstract: A pressure container 1 composed of a reinforcing layer 2 and a liner layer 3, with a hydrogen charging pressure of 30 MPa or higher; and a hydrogen absorbing material and a carrier for holding said hydrogen absorbing material (hydrogen absorbing material portion 4) contained in the pressure container 1 are included, and a volume fraction X of the hydrogen absorbing material with ?m?100 kg/m3 with respect to an internal volume of the pressure container 1 is 5(%)?X?20(%), where am denotes a maximum hydrogen absorption amount per unit volume of the hydrogen absorbing material (kg/m3); X=100 ·Vm/Vi (%); Vi is an internal volume of the pressure container (L); and Vm is a volume of the hydrogen absorbing material in the pressure container (L).

Abstract: A pharmaceutical composition for treating or preventing influenza comprising an oligonucleotide containing a base sequence complementary to a base sequence of a target region containing a translational initiation codon AUG of a PB2 gene or a PA gene, a liposome stable in blood, and a pharmaceutically acceptable carrier or dilute is disclosed. The pharmaceutical composition for treating or preventing influenza can be used in an effective treatment of or prevention of an infection by influenza viruses.

Abstract: A structure of a two-phase steel is controlled by subjecting a steel containing C: 0.05-0.80 mass % to a strain work in a true strain quantity of not less than 0.1 at a temperature zone of &agr;-phase or &ggr;-phase and then applying a magnetic field of 0.1-20 T thereto within a temperature range forming a two-phase zone of &agr;-phase and &ggr;-phase.
