Engineering（科研） 2016年第3期8卷 69-73页

作者： attiq ur-rehman Nasrullah Khan Electrical Engineering Department COMSATS Institute of Information Technology Islamabad Pakistan

This paper reports 10 kV to 100 kV high voltage impulse generator. Generation of variable outputs impulse generator can be designed by combination of flyback transformer and Marx generator which can produce different high voltages. It is a portable device for field. The experimental final results have been taken by using spark gap measurements and voltage divider technique. This high voltage lightning impulse generator produces standard T1/T2 waveshape impulses. The testing of protection devices such as SPD (surge protection device) is extremely important to find out whether these devices can operate in standard conditions or not. That’s why the high voltage lightning impulse generator is developed for such testing. Similarly, our research work consists of modeling and practical design of a 100 kV impulse generator.

蛇行频率是轮轨系统固有的特征参数并随着运行速度的变化而发生连续变化,能够影响车辆系统的模态行为,从而带来了一系列结构共振相关的动力学问题.本文的研究对象从单轮对系统出发扩展至转向架系统和带两级悬挂的整车系统,重点研究了蛇行频率的变化机理及其对车体蛇行稳定性的影响机制.文中提出了一种基于最小模态距离的模态跟踪方法,对蛇行频率和其他模态参数进行连续跟踪,研究了速度激励下轮轨系统及悬挂系数参数对蛇行频率的影响机制.利用极限思想揭示了蛇行频率的饱和机理并给出了频率饱和值的解析表达式.结合模态跟踪方法和正则化的振型及动能幅值分布情况,实现了根轨迹曲线的划分与识别.从模态频率、阻尼比和振型角度,分析并总结了在频率耦合速度(蛇行频率与车体刚性模态频率相等时对应的速度)下的模态行为特征.基于速度与等效锥度的联合变参分析,发现频率耦合速度通过影响最小阻尼比对车体蛇行稳定性产生显著影响.除了模态频率外,车体刚性模态的固有阻尼比也会影响频率耦合速度下的系统最小阻尼比.本文的研究工作揭示了蛇行频率的演变机制,丰富了对蛇行运动现象的理解,为现代轨道车辆的稳定性设计提供了理论依据.

Journal of Cotton Research 2018年第2期1卷 27-34页

作者： HUSSAIN Altaf FAROOQ Jehanzeb AHMAD Saghir MAHMOOD Abid SADIQ M.attiq ZAFAR Ullah Zafar ATHAR Habib-ur-rehman Cotton Research Station Cotton Research Station Ayub Agricultural Research Station Cotton Research Institute Ayub Agricultural Research Institute Institute of Pure and Applied Biology Bahauddin Zakariya University

Background： Hypoxia tolerance studies in cotton are very rare in Pakistan. Unpredicted and excessive rainfalls result in severe losses to cotton crop in many regions of the country due to lack of hypoxia tolerance in current cotton varieties. The genotypes that can tolerate flooding are not reported earlier. The studies were conducted to explore hypoxia tolerance in local germplasm which will help to develop hypoxia tolerant cotton varieties. Method： An experiment with randomized complete different cotton varieties. The genotypes were given conditions. blocks was designed to study the hypoxia tolerance in two treatments i.e., water logged and non-water logged Results： The genotypes showed significant variability for yield, fiber and physiological traits. The hypoxia studies revealed that there is significant reduction for plant height in water sensitive genotype LRA-5166. The genotype MNH-786 showed better yield and MNH-556 showed superior ginning outturn percentage under water logged conditions. Staple length, strength and micronaire values also decreased under hypoxia. Similar pattern of negative effects were observed for Chlorophyll a, b contents and chl a/b ratio. Two hypoxia tolerant cultivars CIM-573 and MNH-564 had significantly higher chlorophyll a （1.664, 1.551） than other cultivars under both normal and waterlogged conditions. There was a significant decrease in total free amino acids in all genotypes/cultivars due to waterlogging. Free amino acid contents were significantly higher in two waterlogging sensitive cultivars, CEDIX and N-KRISHMA, than other cultivars under both non-waterlogged and waterlogged conditions. Waterlogging caused a significant reduction in shoot soluble proteins and increase in shoot proline. The genotype LRA-5166 was the highest in shoot soluble proteins content and showed significant decrease in shoot proline. Conclusions： With respect to yield MNH-786 showed better results and regarding ginning outturn percentage MNH-556 exhibite

Wheat Yield Response to Foliar Fungicide Application against Leaf Rust Caused by Puccinia triticina

Journal of Agricultural Science and Technology(A) 2017年第3期7卷 160-168页

作者： Krishna Dev Joshi Ghulam Ullah attiq ur rehman Muhammad Makky Javaid Javed Ahmad Makhdoom Hussain Angela Pacheco Ibni Amin Khalil Amanullah Baloch International Maize and Wheat Improvement Center (CIMMYT) Islamabad 44000 Pakistan Wheat Research Institute Faisalabad 38000 Pakistan International Maize and Wheat Improvement Center (CIMMYT) Texcoco Edo. de México CP 56130 Mexico Cereal Crops Research Institute Nowshera 24100 Pakistan

A study was conducted on reducing the yield loss of wheat due to leaf rust caused by Puccinia triticina with foliar application of fungicides during the 2014-2015 and 2015-2016 growing seasons at the Wheat Research Institute in Faisalabad, Pakistan. Three fungicides： Folicur （tebuconazole） at 300 mL/ha, Nativo （tebuconazole ＋ trifloxystrobin） at 300 g/ha and Tilt （propiconazole） at 500 mL/ha were applied single or two times to Morocco and Sehar-06 wheat varieties used in the trial. The trial plots were first sprayed at the Zadok＇s scale （ZS） 3 stage and second sprayed between ZS 4.3 and 5.4 stages. The greenness of the trial crop was measured using GreenSeeker. Foliar application of fungicides significantly reduced the loss of grain yield and 1,000-grain weight （TGW） of wheat due to leaf rust in comparison to the control without fungicides application. Of the three fungicides, two times spray of Nativo reduced the grain yield loss of leaf rust susceptible mega wheat variety Sehar-06 by 45%-56% and the loss of TGW by 42%, also giving the highest marginal return in the trial. Single application of Nativo was equally effective as two times spray of Folicur in reducing the loss of wheat grain yield. Two times spray of Folicur was found to be the second choice of fungicide for reducing the yield loss of wheat. The research identified suitable fungicides for reducing the yield loss of wheat due to leaf rust and also generated important scientific knowledge required to manage a sudden outbreak of leaf rust to ensure food security.
