1弹簧圈栓塞海绵窦对直接或硬脑膜动静脉瘘病人的治疗显示文摘确定血管内弹簧圈栓塞海绵窦的成功率及急性并发症的发生率。对19例直接(13例)或硬脑膜动静脉瘘(AVF)f6例)病人行海绵窦弹簧圈栓塞治疗。治疗目的是完全闭塞瘘口。对闭塞程度、症状的减轻及并发症发生率进行回顾性分析。12例病人术后瘘口完全闭塞,6例部分闭塞,1例病人未闭塞并残存较大瘘口。2例AVF早期复发的病人经再次手术后治愈。随访显示,16例病人完全闭塞,3例病人部分闭塞。所有病人结膜水肿及眼球突出均迅速缓解。A.Bink J.Berkefeld M.Lüchtenberg R.Gerlach T.Neumann-Haefelin F.Zanella 刘学焕 2009国际医学放射学杂志2009,32,4:3
2The global Landsat imagery database for the FAO FRA remote sensing survey显示文摘To collect and provide periodically updated information on global forest resources,their management and use,the United Nations Food and Agriculture Organization(FAO)has been coordinating global forest resources assessments(FRA)every 510 years since 1946.To complement the FRA national-based statistics and to provide an independent assessment of forest cover and change,a global remote sensing survey(RSS)has been organized as part of FAO FRA 2010.In support of the FAO RSS,an image data set appropriate for global analysis of forest extent and change has been produced.Landsat data from the Global Land Survey 19902005 were systematically sampled at each longitude and latitude intersection for all points on land.To provide a consistent data source,an operational algorithm for Landsat data pre-processing,normalization,and cloud detection was created and implemented.In this paper,we present an overview of the data processing,characteristics,and validation of the FRA RSS Landsat dataset.The FRA RSS Landsat dataset was evaluated to assess overall quality and quantify potential limitations.P.Potapov M.C.Hansen A.M.Gerrand E.J.Lindquist K.Pittman S.Turubanova M.Løyche Wilkie 2011International Journal of Digital Earth2011,4,1:3

4地球深部流体中的有机质与金刚石生长显示文摘金刚石代表了地球深部微量的碳存在,其成因对于理解行星演化的动力学机制、挥发分循环以及氧化还原状态演变等具有重要意义。在俯冲带环境,金刚石的形成和挥发分的循环密切相关。地球内部的碳通量主要受变质脱碳作用和碳酸盐溶解作用形成的相对氧化的水质流体的调节和控制。在深部C-H-O流体中,碳由随流体迁移到最终饱和形成金刚石的过程主要受碳在流体中溶解度的控制,而后者则受高温高压条件、pH值、氧化还原环境、溶质结构和岩石中缓冲矿物组合等多种因素的影响。Frezzotti M.L 袁超(编译) 2019矿物岩石地球化学通报2019,38,6:3
5开放复位加骨水泥固定治疗继发于缺血坏死的股骨头骨折的初步报告(英文)显示文摘对股骨头缺血坏死的早期治疗已取得较好的结果 ,但对股骨头已塌陷治疗效果并不满意 ,我们采取开放复位加骨水泥内固定治疗这类病人 2 1例 (2 2侧髋 ) ,均属于股骨头坏死Ⅲ期 ,随访 1~ 3年 ,平均 1.7年 ,术前术后根据Har ris髋关节评分标准 ,骨性关节炎指数和SF36健康状况调查表评定治疗效果 ,所有病人均感到术后疼痛减轻 ,功能改善。三个评分指标分别为 5 4.2~ 82 .2 (P <0 .0 5 ) ,5 5 .8~ 2 8.7(P <0 .0 5 ) ,2 7.5~ 43 .1(P <0 .0 5 )。 6例病人进行了全髋置换。该方法简单 ,病人恢复快 ,但长期随访及预后有待进一步研究。伍德 M.L 凯利.S.S 2001中国矫形外科杂志2001,8,6:2

7Process Mineralogy of Lateritic Nickel Ore显示文摘This paper presents a methodology for studying low grade lateritic nickel ore, which usually presents complex mineralogy, with widespread nickel in several mineral phases. The study is focused on determining the mineralogy and the distribution of nickel in the bearing minerals. Laboratory assays comprise homogenization, sampling and particle size analysis. Chemical analyses by X-ray fluorescence are performed in all fractions sizes, while mineralogical assessments by X-ray diffraction are carried out for head sample. The mineralogical composition of the samples and the partition of main elements in the bearing minerals are assayed by size fraction through automated image analysis software (MLA) coupled to a scanning electron microscope (SEM). The chemical compositions of the several minerals identified in MLA are determined during systematic observations on SEM with energy dispersive spectrometer (EDS).Daniel Uliana M.Manuela M.Lé Tassinari Henrique Kah Marco Antonio Angora 2013矿物学报2013,33,S1:2
8食物种类对萼花臂尾轮虫种群增长率的影响(英文)显示文摘在短期慢性观测过程中,食物类型可能是造成萼花臂尾轮虫(Brachionuscalyciflorus)种群繁殖率变化的一种原因。共观测了分别单独投喂10种不同绿藻对轮虫种群增长率的影响。为验证藻青菌是藻类饵料(如绿藻Scenedesmus)有价值的佐剂这一假说,还用蓝细菌单独投喂或与斜生栅藻(Scenedesmusobliquus)混合投喂轮虫进行实验观测。结果发现食物种类对萼花臂尾轮虫种群增长率影响显著。斜生栅藻组获得最大种群增长(1.6/d),而Desmodesmus组增长率最低(0.3/d)。以占斜生栅藻组最大增长的百分率来表示,其它几种绿藻组种群增长由高到低依次为:Desmodesmussubspicatus88%,小球藻(Chlorellavulgaris)83%,单壳缝藻(Monoraphidiumminutum)77%,D.quadricauda74%,S.falcatus71%,S.acuminatus69%,S.pectinatus64%,莱茵衣藻(Chlamydomonasreinhardtii)57%,D.abundans19%。轮虫增长率的差异不能用藻类饵料的大小差异来解释。蓝细菌(Microcystisaeruginosa)和(Synechococcuselongates)不论是单独投喂还是与优良藻类饵料(斜生栅藻)混合投喂都对萼花臂尾轮虫种群增长有抑制作用。这种副作用似乎与微囊藻素无关。该结果不支持无毒蓝细菌可作为与其他绿藻饵料配合使用的优良佐剂这一假说。本研究所观察到的生长变化显示了饵料种类对萼花臂尾轮虫种群增长的影响。M.LüRLING W.BEEKMAN 2006动物学报2006,52,1:2
