1阳澄湖水源水中藻类的去除研究显示文摘藻类是水源水的微污染物,其大量生长将给水厂制水和饮水安全带来诸多影响。试验对比了次氯酸钠氧化除藻,硫酸铝、聚合氯化铝(PAC)混凝沉淀除藻以及氧化和混凝联合除藻的效果,并对次氯酸钠、硫酸铝、聚合氯化铝的投加量以及处理时间进行了优化,确定了经济合理的除藻方案。结果表明,当次氯酸钠投加量为30 mg/L,接触氧化时间为20 min时,除藻率为95.4%;当硫酸铝投加量为140 mg/L时,除藻率为87.3%;当聚合氯化铝投加量为120 mg/L时,除藻率为87.1%;在25mg/L次氯酸钠+ 120mg/L硫酸铝条件下,除藻率为98.3%,沉后水浊度为0.411NTU;在25mg/L次氯酸钠+110mg/L聚合氯化铝条件下,除藻率为98.0%,沉后水浊度为0.379NTU。次氯酸钠的助凝作用大大强化了混凝沉淀效果,从而使沉后水浊度降低,既有效提高了除藻率,又减轻了水厂后续工艺的负荷。景二丹 许小燕 李丛宇 曹荥玉 姚青 关永年 Stephan Küppers 刘洪波 2019中国给水排水2019,35,13:3
2Tracing manufacturing processes using blockchain-based token compositions显示文摘Supply chain traceability is one of the most promising use cases to benefit from characteristics of blockchain,such as decentralization,immutability and transparency,not required to build prior trust relationships among entities.A plethora of supply chain traceability solutions based on blockchain has been proposed recently.However,current systems are limited to tracing simple goods that have not been part of the manufacturing process.We recommend a method that allows for the traceability of manufactured goods,including their components.Products are represented using non-fungible digital tokens that are created on a blockchain for each batch of manufactured products.To create a link between a product and the components that are needed to produce it,we propose“token recipes”that define the amount of tokenized goods required for minting a new token.As input tokens are automatically and transparently consumed when creating a product token,the physical process of producing a new item out of existing components is projected onto the ledger.This ultimately leads to the complete traceability of goods,including the origin of inputs.Evaluating the performance of the system,we show that a prototypical implementation for the Ethereum Virtual Machine(EVM)scales linearly with the amount of the input and goods tracked.Martin Westerkamp Friedhelm Victor Axel Küpper 2020Digital Communications and Networks2020,6,2:3
3Tendon injuries of the hand显示文摘Tendon injuries are the second most common injuries of the hand and therefore an important topic in trauma and orthopedic patients.Most injuries are open injuries to the flexor or extensor tendons,but less frequent injuries,e.g.,damage to the functional system tendon sheath and pulley or dull avulsions,also need to be considered.After clinical examination,ultrasound and magnetic resonance imaging have proved to be important diagnostic tools.Tendon injuries mostly require surgical repair,dull avulsions of the distal phalanges extensor tendon can receive conservative therapy.Injuries of the flexor tendon sheath or single pulley injuries are treated conservatively and multiple pulley injuries receive surgical repair.In the postoperative course offlexor tendon injuries,the principle of early passive movement is important to trigger an'intrinsic'tendon healing to guarantee a good outcome.Many substances were evaluated to see if they improved tendon healing;however,little evidence was found.Nevertheless,hyaluronic acid may improve intrinsic tendon healing.Volker Schffl Andreas Heid Thomas Küpper 2012World Journal of Orthopedics2012,3,6:3
4EXISTENCE OF A NONTRIVIAL SOLUTION FOR CHOQUARD'S EQUATION显示文摘In this article, the authors consider the existence of a nontrivial solution for the following equation: where q(x) satisfies some conditions. Using a Min-Max method, the authors prove that there is at least one nontrivial solution for the above equation.张正杰 Tassilo Küpper 胡爱莲 夏红强 2006Acta Mathematica Scientia2006,26,3:2
5纱线扭结行为的新测试方法显示文摘新研发的ITV纱线扭结测试仪的问世,第一次使批量测试成为可能,还使对纱线扭结行为的测试结果具有了统计学上的重要意义。该仪器除能对纱线扭结行为进行测试外,还能分析不同纱线参数对纱线扭结的影响。此外,判断蒸汽定型对纱线扭结行为的影响是一项重要的研究内容,因为其直接与节能降耗有关。S.Küppers M.üreyen U.Heitmann H.Planck 刘学婧 2010国际纺织导报2010,38,1:2
