1Spontaneous bacterial peritonitis显示文摘Since its initial description in 1964,research hastransformed spontaneous bacterial peritonitis (SBP)from a feared disease (with reported mortality of 90%)to a treatable complication of decompensated cirrhosis,albeit with steady prevalence and a high recurrencerate. Bacterial translocation,the key mechanism in thepathogenesis of SBP,is only possible because of theconcurrent failure of defensive mechanisms in cirrhosis.Variants of SBP should be treated. Leucocyte esterasereagent strips have managed to shorten the 'tap-to-shot' time,while future studies should look into theircombined use with ascitic fluid pH. Third generationcephalosporins are the antibiotic of choice becausethey have a number of advantages. Renal dysfunctionhas been shown to be an independent predictor ofmortality in patients with SBP. Albumin is felt to reducethe risk of renal impairment by improving effectiveintravascular volume,and by helping to bind pro-inflammatory molecules. Following a single episodeof SBP,patients should have long-term antibioticprophylaxis and be considered for liver transplantation.Anastasios Koulaouzidis Shivaram Bhat Athar A Saeed 2009World Journal of Gastroenterology2009,15,9:31

5不同降雨下旱地油菜节水节肥技术对土壤养分及酶活性的调控效应显示文摘为探讨沟垄集雨、秸秆覆盖和减量缓释肥节水节肥技术对油菜生产土壤养分及酶活性的调控效应,在大田定位试验条件下,设置农民习惯栽培(平作+常规肥)、节水栽培Ⅰ(秸秆覆盖+常规肥)、节水栽培Ⅱ(沟垄集雨+常规肥)、节肥栽培(平作+减量缓释肥)、双节栽培Ⅰ(秸秆覆盖+减量缓释肥)和双节栽培Ⅱ(沟垄集雨+减量缓释肥)6种水肥措施,比较分析2016-2017年(多雨年份)和2017-2018年(季节性干旱年份)2种不同降水年型下油菜节水节肥技术对土壤养分及酶活性的影响。结果表明:降水异常偏多对油菜生长的影响大于季节性干旱;双节技术在多雨年型下较习惯栽培增产效应显著,在季节性干旱年型下亦能稳产;在不同降水年型下,双节技术较习惯栽培能提高土壤pH和有机质含量,减少了土壤氮素淋溶损失,保持速效养分稳定释放,同时,能延迟脲酶释放,增加土壤碱性磷酸酶、蔗糖酶、纤维素酶活性,提高作物肥料利用效率及保持土壤肥力,更利于环境保护。综上,单一的节水或节肥技术无法满足西南旱地油菜生产需要。通过秸秆覆盖和沟垄集雨与缓释肥集成的双节技术,能适应不同降水年型下的油菜生产并兼顾环境效应,实现增产与环保的双赢目标。冯军 石超 门胜男 Hafiz Athar Hussain 柯剑鸿 Linna Cholidah 陈锦芬 郭欣 武海燕 冉泰霖 向信华 王龙昌 2020草业学报2020,29,4:6
6欧盟各国的失业保险计划显示文摘在欧盟,社会保障计划资金,包括失业保险的来源和运营是各成员国的责任。欧盟的作用仅限对各国社会保障制度进行协调,保证跨国境失业人员合理流动,使分属于不同社会保障制度的人员都能得到充分的保护。最近,欧盟开始在社会保障制度现代化建设方面推动各成员国展开密切合作。这种合作基于两个前提:一是每个国家都实行社会保障制度,阿塔·侯赛因(Athar Hussain) 2009中国社会保障2009,,1:5
7不同降水下覆盖与缓释肥减量对油菜土壤微生物群落结构的影响显示文摘为探讨沟垄集雨、秸秆覆盖和减量缓释肥集成技术对油菜土壤微生物群落结构的影响,在大田定位试验条件下,设置3种栽培方式(秸秆覆盖、沟垄集雨、传统平作)和4种施肥水平(习惯施肥、缓释肥减量20%、缓释肥减量40%、不施肥),比较分析2016~2017年(多雨年份)和2017~2018年(季节性干旱年份)这2种不同降水年型下油菜土壤微生物群落结构对集成技术的响应.结果表明,不同降雨条件下,秸秆覆盖+缓释肥减量20%(J80)与沟垄覆盖+缓释肥减量20%(M80)较习惯栽培(PC)更利于土壤微生物生长.在多雨年型和季节性干旱年型下,J80与M80能平均分别提高微生物量碳9.94%和10.32%;提高土壤微生物量氮2.38%和1.19%.多雨年型下,土壤微生物磷酸脂肪酸(PLFA)总量较干旱年型降低30.75%,覆盖能有效提高土壤PLFA质量摩尔浓度.多雨年型下土壤细菌、真菌PLFA质量摩尔浓度较干旱年型平均减少33.67%和53.21%;而放线菌PLFA增加13.04%.微生物群落对异常降水具有敏感响应.多雨气候会造成细菌/真菌升高;干旱气候则会增加直链饱和脂肪酸/直链单不饱和脂肪酸及直链单不饱和脂肪酸/环丙烷脂肪酸.通过秸秆覆盖与缓释肥的集成技术,能稳定异常降水下的土壤微环境,缓解水分和养分胁迫,为油菜稳产和可持续发展提供有效途径.冯军 石超 Hafiz Athar Hussain 刘永波 刘天朋 李永洪 刘俊峰 王龙昌 2022环境科学2022,43,8:4

9聚合物对纳米流体通过可拉伸表面的阻力和传热导的影响:一种分子方法显示文摘本文研究了聚合物对纳米流体通过均匀加热的可渗透的垂直拉伸表面的阻力降低和热传导增强的影响,研究的重点是分析纳米流体中聚合物对阻力系数、努塞尔数和舍伍德数的影响。利用分散模型研究纳米颗粒存在下的流体流动和传热行为。选择分子方法来探索基流体中添加聚合物的影响。添加聚合物会在动量方程中产生了一个额外的应力。对控制边界层方程进行数值求解,研究工程感兴趣的物理量对不同流量参数的依赖关系。由于聚合物添加剂的存在,阻力系数、努塞特数和舍伍德数都有所减少。ADEEL Ahmad MARIA Athar YASIR Khan 2022Journal of Central South University2022,29,12:4
10Intelligent cluster routing scheme for flying ad hoc networks显示文摘Flying ad hoc networks are used for many critical tasks.The network formation for routing data becomes difficult because of the mobility of unmanned aerial vehicles(UAVs).To solve the communication issue,we propose an intelligent cluster routing scheme for flying ad hoc networks(CRSF).Cluster head(CH)selection in our proposed methodology is based on fitness,which is determined by the position and UAVs’residual energy.For the efficient management of UAV swarm,a cluster management mechanism is also proposed,inspired by moth flame optimization.In CRSF,for stable cluster maintenance,a CH re-selection mechanism is proposed in detail,which helps maintain the cluster for effective topology management.A routing mechanism for UAV communication is proposed for CRSF.The route selection for transmission of information is performed using the route identification function based on the Euclidean distance and residual energy.The performance of the proposed CRSF is evaluated and compared with the existing routing algorithms.Ali KHAN Somaiya KHAN Athar Shahzad FAZAL Zhongshan ZHANG Adnan Omer ABUASSBA 2021Science China(Information Sciences)2021,64,8:4
11Antibacterial activity of leaves extracts of Trifolium alexandrinum Linn,against pathogenic bacteria causing tropical diseases显示文摘Objective:To investigate antibacterial potential of Trifolium alexandrinum(T.alexandrinum) Linn,against seven gram positive and eleven gram negative hospital isolated human pathogenic bacterial strains responsible for many tropical diseases.Methods:Non-polar and polar extracts of the leaves of T.alexandrinum i.e.,hexane,dichloromethane(DCM),ethyl acetate(EtOAc), methanol(MeOH) and aqueous(AQ) extracts at five different concentrations(1,2,5,10 and 15 mg/ mL) were prepared to evaluate their antibacterial value.NCCL standards were strictly followed to perform antimicrobial disc susceptibility test using disc diffusion method.Results:Polar extracts demonstrated significant antibacterial activity against tested pathogens.EtOAc and MeOH extracts showed maximum antibacterial activity with higher inhibition zone and were found effective against seventeen of the tested pathogens.While AQ plant extract inhibited the growth of sixteen of the test strains.EtOAc and MeOH plant extracts inhibited the growth of all seven gram positive and ten of the gram negative bacterial strains.Conclusions:The present study strongly confirms the effectiveness of crude leaves extracts against tested human pathogenic bacterial strains causing several tropical diseases.Since Egyptian clover is used as a fodder plant,it could be helpful in controlling various infectious diseases associated with cattle as well.Abdul Viqar Khan Qamar Uddin Ahmed Indu Shukla Athar Ali Khan 2012Asian Pacific Journal of Tropical Biomedicine2012,2,3:3
