    摘要: A standard blood filter paper for use in diagnosis of histidinemia, comprising a piece of filter paper, and a blood material infiltrated in the above filter paper containing a known concentration of histidine and at least one salt selected from the group consisting of a dithionite, a disulfite and a bisulfite. The standard blood filter paper can be preserved for a long term at -20.degree. C.

    摘要: A quick hardening cement-asphalt composition used as a grout for a ballast-filled track structure comprising(a) 100 parts by weight of a cement composition prepared by adding to portland cement about 10 to 50% by weight of a mixture of a calcium aluminate-series mineral and calcium sulfate in a weight ratio of about 1:0.3 to 1:3; about 0.05 to 10% by weight of an inorganic salt, and about 0.05 to 3% by weight of at least one of an organic carboxylic acid, an organic hydroxycarboxylic acid and a salt thereof, and(b) about 30 to 400 parts by weight of an asphalt emulsion containing about 0.2 to 8% by weight of a polyoxyethylene alkyl phenyl ether, polyoxyethylene alkyl ether, polyoxyethylene alkyl ester, sorbitan alkyl ester, polyoxyethylene sorbitan alkyl ester or sucrose fatty acid ester nonionic emulsifier and about 0.05 to 2% by weight of a multivalent metal chloride, calculated as the multivalent metal ion.
