| 1 | 影像引导下乳腺癌的聚焦超声消融:现状、挑战及未来发展方向显示文摘影像引导下聚焦超声(FUS)消融为无创性操作,用于治疗良恶性乳腺肿瘤。可在实时超声或MRI引导下进行消融。过去20年第一阶段研究证实,在MRI或超声引导下进行乳腺肿瘤的FUS消融技术是可行且安全的。通过测量肿瘤完全坏死病例所占的比例。对FUS消融乳腺肿瘤的效果作一全面概述。肿瘤消融成功率为20%-100%,此范围取决于FUS系统的类型、成像技术、消融方法及病人的选择。目前还存在一些与乳腺肿瘤FUS消融相关的具体问题, | A.C.Schmitz D.Gianfelice B.L.Daniel W.P.Mali M.A.van den Bosch 秦乃姗 | 2008 | 国际医学放射学杂志2008,31,5: | 9 |
| 2 | A case study of the stability of a non-typical bleeder entry system at a U.S.longwall mine显示文摘Longwall abutment loads are influenced by several factors,including depth of cover,pillar sizes,panel dimensions,geological setting,mining height,proximity to gob,intersection type,and size of the gob.How does proximity to the gob affect pillar loading and entry condition?Does the gob influence depend on whether the abutment load is a forward,side,or rear loading?Do non-typical bleeder entry systems follow the traditional front and side abutment loading and extent concepts?If not,will an improved understanding of the combined abutment extent warrant a change in pillar design or standing support in bleeder entries?This paper details observations made in the non-typical bleeder entries of a moderate depth longwall panel—specifically,data collected from borehole pressure cells and roof extensometers,observations of the conditions of the entries,and numerical modeling of the bleeder entries during longwall extraction.The primary focus was on the extent and magnitude of the abutment loading experienced due to the extraction of the longwall panels.Due to the layout of the longwall panels and bleeder entries,the borehole pressure cells(BPCs)and roof extensometers did not show much change due to the advancing of the first longwall.However,they did show a noticeable increase due to the second longwall advancement,with a maximum of about 4 MPa of pressure increase and 5mmof roof deformation.The observations of the conditions showed little to no change from before the first longwall panel extraction began to when the second longwall panel had been advanced more than 915 m.Localized pillar spalling was observed on the corners of the pillars closest to the longwall gob as well as an increase in water in the entries.In addition to the observations and instrumentation,numerical modeling was performed to validate modeling procedures against the monitoring results and evaluate the bleeder design.ITASCA Consulting Group’s FLAC3D numerical modeling software was used to evaluate the bleeder entries.The results of the models indicated only a minor increase in load during the extraction of the longwall panels.These models showed a much greater increase in stress due to the development of the gateroad and bleeder entries--about 80%development and 20%longwall extraction.The FLAC3D model showed very good correlation between modeled and expected gateroad loading during panel extraction.The front and side abutment extent modeled was very similar to observations from this and previous panels. | T.M.Klemetti M.A.Van Dyke I.B.Tulu D.Tuncay | 2020 | International Journal of Mining Science and Technology2020,30,1: | 2 |

| 4 | 海员疲劳:有关缓解方式的综述显示文摘疲劳对船员健康和安全的严重影响以及其在海运业、学术界引起的广泛关注,表明对海上作业预防性干预措施进一步研究的重要性。本研究对缓解海上作业疲劳方式的文献进行分析,对有关集体和个体的海员疲劳缓解的国际立法及基于研究的建议进行了综述。鉴于船员疲劳的发生的频度及其结果的严重性,我们应该重新审视当前法律法规的有效性和行业的依从性,国际商船的人员配备,以及海上船员的工作、生活和睡眠环境的优化等问题。考虑海运作业的特殊性,例如,天气、不可避免的轮班作业和时区跨越,应进一步评价预防性干预措施的可能性,包括疲劳预测工具和个体疲劳缓解管理系统等。 | J?rgen Riis Jepsen 赵志葳 涂铭珊 Wessel M.A.van Leeuwen | 2016 | 环境与职业医学2016,33,9: | 1 |
| 5 | 结构与键合显示文摘经验告诉人们,飞近固体表面的原子或分子总是存在着潜在的吸引力,因此有一定的几率为固体表面所吸收;这就产生了叫做“吸附”的现象。在寻常的环境条件(大气压,300K,氧、氮、水蒸汽和碳氩化合物等)里,所有固体表面都覆盖着吸附质层,并经常可以检测出多层的。吸附质层的实地存在,影响了化学、机械和电子学的表面特性。附着、润滑、化学腐蚀点和光导性等正是许多宏观表面。 | G.A.Somoriai M.A.Van Hove 莫纯昌 | 1981 | 电子器件1981,11,3: | 0 |
| 6 | 海员疲劳:关于危险因素的综述显示文摘疲劳对船员健康和安全的影响已经在海运业以及学术界引起了广泛的关注。本研究对研究海上作业疲劳相关危险因素的文献进行分析。由于该领域文献非常有限,因此,必要时收录与船员有相似暴露特征的人群研究,如实施轮班的工作人群。海上工作涉及疲劳相关的多个外部危险因素,比如工作紧张、不规律工作、睡眠的定型和定量指标、工作负荷和诸如噪声和船体运动等物理因素。疲劳的易感性有个体差异。鉴于船员疲劳发生的高频度及其带来后果的严重性,在可能的范围内消除疲劳的危险因素尤为重要。 | J?rgen Riis Jepsen 赵志葳 涂铭珊 Wessel M.A.van Leeuwen 金克峙 | 2016 | 环境与职业医学2016,33,8: | 0 |
