[背景]饮用水砷暴露与心脏疾病相关联,然而内在的机制尚不明确。[目的]评估饮用水砷暴露史与心率校正的QT(QTc)、PR和QRS间期延长之间的关联。[方法]从砷对健康影响的纵向研究中选择1715名基线入组的参加者进行研究。评估2005—2010年间,井水中的砷暴露和尿液样本与心电图(ECG)参数的关联,自基线开始平均跟踪了5.9年。[结果]QTc延长的定义为男性QTc≥450ms,女性≥460ms。井水中砷每增加1-SD(108.7μg/L),QTc延长的调整比值比(OR)为1.17(95%CI:1.01～1.35)。正相关仅限于女性,基线时井水和尿液中的砷每增加1-SD,女性调整后ORs分别比为1.24(95%CI:1.05～1.47)和1.24(95%CI:1.01～1.53);与之相比,男性调整后ORs分别为0.99(95%CI:0.73～1.33)和0.86(95%CI:0.49～1.51)。基线时井水砷或尿砷与女性或男性的PR或QRS间期延长之间无明显的关联。[结论]长期饮用水砷暴露(平均95μg/L,全距为0.1～790μg/L)与女性之后的QT间期延长相关联。在今后的纵向研究中,ECG的反复测量对于评估暴露变化的影响将具有重要意义。

WISE USE OF WETLAND FOR SUSTAINABLE LIVELIHOOD THROUGH PARTICIPATORY APPROACH:A CASE OF ADAPTING TO CLIMATE CHANGE

引用

湿地科学 2005年第3期3卷 161-166页

作者： Haq A H M Rezaul Tapan kumar ghosal Pritam Ghosh M Aminul Islam Wetland Resource Development Society Khulna 9100 BangladeshWetland Resource Development Society Khulna 9100 BangladeshWetland Resource Development Society Khulna 9100 BangladeshUnited Nations Deuelopment ProgramDhaka 1207 Bangladesh

The facts showed that the number of unemployment people is increasing and a large part of them live in the low-lying areas to be facing the challenge from impacts of climate change. So adaptive capacity of the poverty level for sustainable livelihood in vulnerable wetlands is related to coping with local climate change. This paper focuses on soil-less agriculture (Hydroponics) as an alternative source of livelihood means for the communities having no lands for cultivation. Approximately half of Bangladesh is covered with wetlands. The prospect of enormous productivity lies in the development of wetland resources. The soil-less agriculture is an indigenous practice in the middle of southwestern part of Bangladesh. The people who lives within the wetland ecosystems uses locally available paddy straws, water hyacinths and various invasively aquatic plants for making the floating mat or organic bed on which crops, vegetables and seedlings are grown. The productivity of this farming system is much higher than that of terrestrials agricultural and the system can support fisheries of open water. The compost generated from organic refuse bed is a kind of enriched nutrient and can act as a soil conditioner. It would be a major source of nutrients in aquaculture as well. The system is capable to ensure more agriculture production by restoring wetlands from aquatic invasive plant. In addition, the technology included of the system is friendly to ecosystem of wetlands.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced *** paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS *** taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet *** in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.
