Abstract: A laminate has an olefin-aromatic vinyl compound-aromatic polyene copolymer and a metal foil. The number average molecular copolymer weight is between 5000 and 100000; the aromatic vinyl compound monomer is aromatic vinyl compound having between 8 and 20 carbon atoms, and the aromatic vinyl compound monomer unit content is between 10 and 60 mass %; the aromatic polyene is selected having between 5 and 20 carbon atoms and vinyl and/or vinylene groups in the molecule, the content derived from the aromatic polyene unit is between 1.5 and 20 pieces per number average molecular weight; and the olefin is selected having between 2 and 20 carbon atoms, being ethylene alone, or having a mass ratio of α-olefin monomer components other than ethylene to an ethylene monomer component contained in the olefin, of 1/7 or less, and the total monomer units of the olefin, aromatic vinyl compound, and aromatic polyene is 100 mass %.

Abstract: Disclosed is an ulcer model used to practice a procedure including hemorrhage arrest, the ulcer model including a model main body which includes upper and lower surfaces facing each other and a tubular simulated blood vessel path provided between the upper surface and the lower surface and having an inlet opening and an outlet opening. The upper surface includes a ring-shaped raised surface that rises in a thickness direction of the model main body and a simulated ulcer surface that is a recessed bottom surface surrounded by the raised surface. The simulated blood vessel path extends from a part other than the upper surface of the surfaces of the model main body to the simulated ulcer surface or an area in the vicinity of the inside thereof.

Abstract: Provided is a method for producing carbon nanotibers having excellent conductivity, crystallinity and dispersibility. A method for producing carbon nanofibers, which uses an activated species mainly composed of cobalt as a catalyst, while using carbon monoxide as a carbon source. The catalyst is obtained by having a carrier, which is composed of an oxide having a specific surface area of 0.01-5 m2/g and containing magnesium, support 3-90% by mass of the activated species. By controlling the reaction temperature, the carbon monoxide partial pressure and the gas flow rate of the carbon monoxide, CNF having more excellent conductivity, crystallinity and dispersibility can be produced, thereby obtaining carbon nanofibers having excellent conductivity, crystallinity and dispersibility.
