Abstract: A determination unit determining whether or not a telephone number of a called side included in a received telephone call control signal is registered in an advertising contract object that is stored in a memory unit and that includes a telephone number of an advertising contractant who performs a contract with an advertising provider and advertising provider identification information identifying the advertising provider with whom the advertising contractant performs the contract, an extraction unit extracting advertising data of the advertising provider identified by the advertising provider identification information corresponding to the telephone number of the called side from a memory unit when the telephone number of the called side is determined to be registered in the advertising contract object in the determination unit, and an advertising data transmission control unit transmitting the advertising data extracted in the extraction unit to a telephone apparatus identified by a telephone number of a ca

Abstract: A drop in measurement accuracy of biosensors, due to interferents in a measurement sample is avoided by an arrangement wherein: a hydrogen peroxide electrode 2 is formed on an insulated base 1, and then a .gamma.-aminopropyltriethoxysilane film 3, an acetylcellulose film 4, a perfluorocarbonsulfonic acid resin film 5, an organic macromolecular film 6 incorporating an immobilized enzyme with catalytic properties, and a polyalkylsiloxane film 7, are sequentially formed on the electrode 2.

Abstract: Method for the remediation of polluted soils by using microorganisms under anaerobic conditions wherein the degradation action of pollutants such as tetrachloroethylene, nitrate or nitrite by microorganisms under anaerobic conditions is induced or promoted by the addition of silicon to said polluted soils, without any risk of secondary pollution.

Abstract: A lactate oxidase (LOD15, LOD1, LOD16) shows an enzymatic activity under a reaction represented by "L-lactate+oxygen.fwdarw.pyruvic acid+hydrogen peroxide". A DNA molecule comprises nucleotide sequences which code on expression for a lactate oxidase (LOD15, LOD1, LOD16).

Abstract: A plasmid pSTK1 having about 1880 bp and the restriction map set forth in FIG. 1 and plasmids pSTE33 and PSTK3 derived therefrom. The plasmids are capable of stable replication in thermophilic bacteria.

Abstract: A glucose sensor in which a gel is in contact with a pH sensing element. The gel contains immobilized glucose oxidase and gluconolactonase (EC 3.1.1.17). Gluconolactonase is present in an amount effective to accelerate the hydrolysis of D-glucono-.delta.-lactone.
