摘要:
A composition for use in the oral cavity is disclosed. The composition comprises (A) an antibacterial compound represented by the following general formula (1),A.sup.m+ .multidot.X.sub.m.sup.- (1)wherein A.sup.m+ is a nitrogen-containing antibacterial cation and the counter anion X.sup.- represents a monoalkyl phosphate ion, a monoalkenyl phosphate ion, a monoalkyl phosphonate ion, or a monoalkenyl phosphonate ion having a linear or branched alkyl or alkenyl group with 8 to 20 carbon atoms, and m is a valence of the cation A, and (B) a vehicle for use in the oral cavity. It exhibits a remarkablely rapid and continued disinfection effect action against oral cavity bacteria, while providing a good taste. Its disinfection effect is not reduced in the presence of surfactants. In addition, it does not color the tooth.

摘要:
A bactericidal composition comprises didecyldimethyl didecyldimethylammonium chloride and an alkylene oxide adduct of a polyhydric alcohol being trivalent or more and is effective bactericidally even to feces of a cattle stall.
摘要:
A moving image distribution server selects an intermediate value map of at least one channel during execution of a rendering processing of a subsequent stage for a first screen, and determines, for each set block, whether to perform inter-frame coding by referring to a corresponding intermediate value map generated for a second screen rendered before the first screen. The moving image distribution server performs coding in accordance with the determination result and sends coded moving image data to an external device after the rendering processing of the subsequent stage for the first screen has ended. The determination result is sent to the external device before generation of the coded moving image data of the first screen is completed.
摘要:
A biocide composition comprises an effective amount of a biocide and an effective amount of a biocide activator selected from the group consisting of an alkyl phosphate, an alkenyl phosphate, a hydroxyalkyl phosphate, a polyoxyalkylene alkyl ether phosphate, a salt thereof, a polyoxyalkylene alkenyl ether phosphate, a salt thereof, a polyoxyalkylene hydroxyalkyl ether phosphate and a salt thereof.
摘要:
A milk replacer composition for infant cattle and a method of breeding infant cattle by feeding on the milk replacer composition are disclosed. The composition comprises a skim milk powder and/or a soybean meal as a main component, and at least 0.5% by weight of a triglyceride of a medium-chain fatty acid having from 6 to 10 carbon atoms. The milk replacer composition is effective to prevent or reduce the incidence of scours and the death rate of infant cattle.
