Strategic planning and designing of a hospital disaster manual in a tertiary care, teaching, research and referral institute in India

BACKGROUND: As per the "Disaster Management Act, 2005" of India, it is mandatory for government hospitals in India to prepare a disaster plan. This study aimed to prepare a disaster manual of a 1 900 bed tertiary care hospital, in consultation and involvement of all concerned stakeholders.METHODS: A committee of members from hospital administration, clinical, diagnostic and supportive departments worked on an initial document prepared according to the Act and gave their inputs to frame a final disaster manual.RESULTS: The prepared departmental standard operating procedures involved 116 people(doctors and paramedical staff), and were then synchronized, in 12 committee meetings, to produce the final hospital disaster manual.CONCLUSIONS: The present disaster manual is one of the few comprehensive plans prepared by the stakeholders of a government hospital in India, who themselves form a part of the disaster response team. It also helped in co-ordinated conduction of mock drills.

冲击角度与旋转速度对铝冲蚀行为的影响(英文)

将工业纯铝暴露在一定浓度的泥浆中,样品以不同的角度固定,并在不同速度下旋转,通过质量损失来测量样品的磨损率。结果表明,当冲击角度小于90°时,样品的磨损率随冲击角度的增加而增加。与传统的认识不同,铝的最大磨损率出现在冲击角为90°,而不是出现在冲击角45°。旋转速度的增加将导致磨损率呈指数增加。这一结果与磨损表面的金相分析一致。

静电检验密写字迹

用于书写而又需要显现处理才能看见字迹的材料,称为密写墨水或隐显墨水或假墨水。实际上,任何不易蒸发的无色液体(包括水),都可以作为密写墨水。牛奶、唾液、汗、尿和其它无色体液,葱、蒜、柠檬等植物汁、水果汁或树叶汁,氯化钠、硫酸铜、硫酸氨、硝酸钴、无色盐液以及盐酸、草酸、醋等稀酸,常见的苏打水、

On Testing Equality of K Multiple Correlation Matrices

Coutsourides derived an ad hoc nuisance paratmeter removal test for testing equality of two multiple correlation matrices of two independent p variate normal populations under the assumption that a sample of size n is available from each population. This paper presents a likelihood ratio test criterion for testing equality of K multiple correlation matrices and extends the results to the testing of equality of K partial correlation matrices.

确保大型电动机高质量的绝缘系统——设计和测试要求

近期，NTPC公司两个项目中的一些高压电动机，在运行一年期间出现了绕组故障。包括轴承故障、绕组电缆头连接故障和绕组端部绝缘故障。审查中发现，在制造过程中的某些确保电机绝缘系统安全的重要要求未得到重视。端部绕组制造过程中常见的缺陷是：母线连接处钎焊质量不高。制造工艺不良，造成不均匀的空气间隙。＋选择的电缆和电缆头捅件尺寸不当．导致过热和随后的故障。＋预浸渍过程在不受控制的（非空调）环境中进行。本文讨论了发生故障的类型，分析了产生故障的原因和改善措施。提出了在电机制造和测试中的最好做法，确保绝缘系统的高质量。本文讨论两个相邻的线圈之间的最小间隙的重要性。建议保持同相和异相的两个相邻线圈绝缘表面之间的最小的间隙。强调使用先进的数控线圈包带机和线圈成型机来代替传统的设备，保证线圈设计形状．自动的线圈成型和自动的包带机避免了线圈表面皱褶、打结和坎线时对线圈的敲打，保持了足够的端部问隙．更蓖要的是保证了固化层的质量。本文介绍了包带方法对电机寿命的影响。论述了机器包带相比手：I：包带的优点。

The Petrov–Galerkin finite element method for the numerical solution of time-fractional Sharma–Tasso–Olver equation

In this paper,time-fractional Sharma-Tasso-Olver(STO)equation has been solved numerically through the Petrov-Galerkin approach utilizing a quintic B-spline function as the test function and a linear hat function as the trial function.The Petrov-Galerkin technique is effectively implemented to the fractional STO equation for acquiring the approximate solution numerically.The numerical outcomes are observed in adequate compatibility with those obtained from variational iteration method(VIM)and exact solutions.For fractional order,the numerical outcomes of fractional Sharma-Tasso-Olver equations are also compared with those obtained by variational iteration method(VIM)in Song et al.[Song L.,Wang Q.,Zhang H.,Rational approximation solution of the fractional Sharma-Tasso-Olver equation,J.Comput.Appl.Math.224:210-218,2009].Numerical experiments exhibit the accuracy and efficiency of the approach in order to solve nonlinear fractional STO equation.

目前大型火电汽轮发电机状态监控的趋势

在当今时代，随着大量新技术的研发，在现有的系统中大力应用新技术，才是目前最为需要进行的事。现在有各种各样针对不同电气设备检测的诊断工具。使用者只需要分析并找出，哪种更能满足所需即可。先进的诊断技术，大大帮助了像发电机这样的关键电气设备的正常运行。如今可以连续地进行检测，当有任何预定义因素变化，如温度升高、电压上升、电流增大等情况发生时，进行报警。发电机运行时，设备的检测要参考初始的运行状态和测试的数据，并将数据随时间的变化进行叠加。如今我们将注意力集中在保持电厂设备的健康和减少维修测试的经费上，并且要逐步脱离传统的按时间定期检修的体制，选择“状态检修”，即一瀹当时机需修时修”。这项工程就需要一套系统，这是一个在初期阶段能够检测出错误，并在确保高质量、高可靠性、低成本以及容纳自我监控，满足顾客需求的系统。本论文描述的了多种检测设备，并以大型水冷发电机为例进行研究。本论文只对已构建的，对系统极为重要的，并具备真实输出结果的监控系统作为研究对象。
