    • Processes for biofilm or microorganism growth control in an aqueous system such as a pulp, paper or board manufacturing system are described in which a halogenated hydantoin is added to the aqueous system in combination with haloamine, chlorine dioxide or a combination thereof. The halogenated hydantoin is preferably a fully or partially halogenated dialkyl hydantoin, and more preferably 5,5-dimethyl hydantoin or 5-methyl-5-ethyl hydantoin. The haloamine is preferably a monohaloamine, dihaloamine, trihaloamine, or a combination thereof, and more preferably monochloramine, monobromamine, bromochloroamine or a combination thereof. The halogenated hydantoin is preferably added to the aqueous system in portions of the system susceptible to gas phase corrosion, such as the short loop of the system, and the haloamine and chlorine dioxide are preferably added to other portions of the system. The halogenated hydantoin and haloamine and/or chlorine dioxide maintain good compatibility with each other in the absence of excess free chlorine.
    • 描述了在水系统如纸浆,纸或板制造系统中的生物膜或微生物生长控制的方法,其中将卤代乙内酰脲与卤胺,二氧化氯或其组合组合加入到水系统中。 卤化乙内酰脲优选为完全或部分卤化的二烷基乙内酰脲,更优选为5,5-二甲基乙内酰脲或5-甲基-5-乙基乙内酰脲。 卤代胺优选为单卤代胺,二卤代胺,三卤代胺或其组合,更优选一氯胺,一溴胺,溴氯胺或其组合。 卤化乙内酰脲优选在易于气相腐蚀的系统的部分系统中加入到水系统中,例如系统的短路,并且卤胺和二氧化氯优选加入系统的其它部分。 卤代乙内酰脲和卤代胺和/或二氧化氯在不存在过量游离氯的情况下保持彼此良好的相容性。

    • Computer-implemented methods, systems, and computer program products for document authentication and identification using a large-scale distributed system are provided. A method includes receiving a digitized document at a trusted system managed by a trusted third-party that is separate from a creator of content in the digitized document. The digitized document is compared to a set of markers to determine whether the digitized document includes one or more of the markers, and in response thereto, information associated with the one or more markers is extracted using a decoder on the trusted system according to encoding strategies. The method further includes generating a comparison registration identifier on the trusted system as a summary of the extracted information and the one or more markers, and comparing the comparison registration identifier with a stored registration identifier in an encoding history via the trusted system to authenticate and identify the received digitized document.
    • 提供了使用大规模分布式系统进行文档认证和识别的计算机实现的方法,系统和计算机程序产品。 一种方法包括在由数字化文档中的内容的创建者分离的受信任的第三方管理的受信系统处接收数字化文档。 将数字化文档与一组标记进行比较以确定数字化文档是否包括一个或多个标记,并且响应于此,根据编码策略,使用可信系统上的解码器提取与一个或多个标记相关联的信息 。 该方法还包括在可信系统上生成比较注册标识符作为提取的信息和一个或多个标记的摘要,并且通过可信系统将比较注册标识符与编码历史中存储的注册标识符进行比较,以验证和识别 收到的数字化文件。
