1Traveling Wave Based Single-Phase-to-Ground Protection Method for Power Distribution System显示文摘Correct detection and identification of single-phase to-ground faults not effectively grounded in distribution systems is a major challenge for protection engineers.This paper proposes a novel traveling wave based protection method to solve this problem.The proposed method compares the polarities of current and voltage traveling waves measured immediately after the fault inception to determine the fault direction.Nuisance tripping is avoided by using the power frequency voltages detected on the busbar to inhibit operation.The power frequency voltages ensure that the system does not mal-operate due to noise and also provide discrimination for phase-to-phase and three-phase faults.The wavelet transform and modulus maxima theories are used to extract the polarity of traveling waves measured at the relaying point.The simulation studies demonstrate correct operation of protection,which is independent of fault distance,fault inception angle,fault path resistance,and the method used for neutral grounding.Xinzhou Dong Jun Wang Shenxing Shi Bin Wang Bak Dominik Miles Redfern 2015CSEE Journal of Power and Energy Systems2015,1,2:15
2中国各地管理价值观之差异显示文摘在中国吸纳现代市场要素和实现经济现代化的过程中,中国经理拥有什么样的传统价值观,哪些传统价值观将被保留,哪些价值观将被放弃。本研究在中国的3个不同地区考证了经理个人的价值观。我们发现中国价值观调查(Chinese Culture Connection,1987)的一项因子分析与原始研究中所描述的特点的相同之处甚少。我们辨别出反映儒家学说的5个因子。我们的假设是:在中国的不同地区,工业化和现代化水平越高,经理们的价值观就越接近于西方市场经济为动力的价值观。在200名经理人员抽样中,我们的这项假设得到了部分证实。Kylie Redfern 戴复 马小木 2005管理世界2005,21,5:11
3Metamorphic Temperature Investigation of Coexisting Calcite and Dolomite Marble Examples from Nikani Ghar Marble and Nowshera Formation,Peshawar Basin,Pakistan显示文摘用从从北巴基斯坦的 Nikani Ghar 云石和 Nowshera 形成的云石样品,变态的温度的决心在方解石白云石 solvus 地温计的帮助下被承担。云石的二种类型,也就是说,方解石白云石大理石和忍受石英的方解石白云石大理石被选择。Petrographic 和白云石样品的扫描电子显微镜分析显示了不同谷物尺寸。X 光检查衍射技术显示了方解石 MgCO 3 内容直到 7.93 mol.% 。Nikani Ghar 云石样品从 Nowshera 形成作为与样品相比显示出 MgCO 3 的更低的内容。calcite-dolomite-quartz 云石也显示出相对更低的 MgCO 3 内容和因此相当低的温度(~ 500 使活跃之物转变生长因素贝它 1 独立,而吗?Muhammad Fahad Yaseen Iqbal Mohammad Riaz Rick Ubic Simon A.

5Visible light photocatalytic bismuth oxide coatings are effective at suppressing aquatic cyanobacteria and degrading free-floating genomic DNA显示文摘Access to safe drinking water free from microbial pollution is an issue of global concern. The use of photocatalytic thin films in water treatment has focused on titanium dioxide, which requires UV-activation, proving a potential barrier to upscaling and implementation in the real world. Visible-light-activated photocatalytic thin films, such as bismuth oxide, have recently been shown to have antimicrobial properties. However, more understanding of the photocatalytic effect on the microbial population in water is required. Glass beads coated with bismuth oxide were incubated with either Microcystis aeruginosa, Anabaena sp. or free-floating genomic DNA. The presence of bismuth oxide-coated glass beads was able to rapidly stop a population of cyanobacteria from increasing. The coated beads were also able to degrade genomic DNA. Leachate from the beads showed no increase in toxicity against human liver cells. This data demonstrates the efficacy of bismuth oxide-coated glass beads for controlling potentially dangerous cyanobacterial populations, whilst potentially reducing the amount of free-floating genomic DNA(an essential issue in the face of antimicrobial resistance) – all of which should be essential considerations in emerging water treatment technologies.James Redfern Marina Ratova Andrew PDean James Pritchett Matthieu Grao Joanna Verran Peter Kelly 2021Journal of Environmental Sciences2021,33,6:2
