The addition of hexagonal-close-packed(hcp)non-rare-earth elements Zr,Ti and Co,to the 10-component hep rare-earth-based high-entropy alloys(HEAs)with a composition of ScYLaNdGdTbDyHoErLuX(X=Zr,Co and Ti)was *** enthalpy of mixing between elements was found to have a significant effect on the formation of *** addition of Co combines with elements that had a strong chemical affinity to form intermetallic compounds by the effect of *** was added with all elements with poor chemical affinity and exhibited rejection to form a phase *** were the two terminal manifestations of the role of enthalpy over *** of Zr was soluble in the matrix under the action of entropy,while the other part had a greater affinity for Sc than the other elements to form a precipitate under the action of *** was the result of the local balance between the effect of enthalpy and *** solid solution of the elements had different degrees of strengthening effect,among which Zr had the most excellent strengthening effect from 185 to 355 MPa,so the solid solution strengthening model and precipitation strengthening model were proposed to predict the strength of the alloy with the addition of Zr effectively.

Achieving work hardening in metallic glass matrix composites(MGMCs) is the key to the extensive use of these attractive materials in structural and functional *** this study,we investigated the formation of nanoscale boundaries resulted from the interaction between matrix and dendrites,which favors the work-hardening deformation in an in-situ Ti41Zr32Ni6 Ta7 Be14 MGMC with β-Ti dendrites in a glassy matrix at room *** microstructures of samples after tension were observed by highresolution transmission electron microscopy(HrTEM) and X-ray diffraction(XrD).The work-hardening mechanism of the present composites involves:(1) appearance of dense dislocation walls(DDWs),(2)proliferation of shear bands,(3) fo rmation of boundaries on the nanoscale,and(4) interactions between hard and soft phases.A theoretical model combined with experimental data reveals the deformation mechanisms in the present work,proving that the in-situ dendrites with outstanding hardening ability in the glass matrix can provide the homogeneous deformation under tensile loading at room temperature.

Background/Aims: Longitudinal studies on the relationship between hepatitis B virus (HBV) genotypes and reactivation of hepatitis B and progression to cirrhosis were very rare. Methods: Liver biochemistry, virological markers and ultrasound were monitored in 202 hepatitis B e antigen (HBeAg)positive patients with normal alanine aminotransferase (ALT) at baseline for 3- 20 (average 10.8) years, and the outcome was correlated with HBV genotypes. results: There were 150 genotype B and 52 genotype C patients. Hepatitis activity during the HBeAg- positive phase showed no significant difference. However, genotype B was associated with a significantly earlier and higher rate of HBeAg seroconversion. HBeAg seroconversion correlated with age at entry for genotype B and with ALT levels for genotype C. reactivation of hepatitis B was significantly more common in genotype C patients. Five genotype B and 10 genotype C patients progressed to cirrhosis. Multivariate analysis revealed that genotype C (P=0.03) and reactivation of hepatitis B (P=0.0004) were independent factor predictive of cirrhosis. Conclusions: rate and factors of HBeAg seroconversion, and rate of reactivation of hepatitis B differed between genotype B and genotype C patients. Genotype C and reactivation of hepatitis B were associated with increased risk of cirrhosis.

The chemical element distributions always strongly affect the deformation mechanisms and mechanical properties of alloying ***,the detailed atomic origin still remains unknown in highentropy alloys(HEAs)with a stable random solid ***,considering the effect of elemental fluctuation distribution,the deformation behavior and mechanical response of the widely-studied equimolar random Co Cr Fe Mn Ni HEA are investigated by atomic simulations combined with machine learning and micro-pillar compression *** elemental anisotropy factor is proposed,and then used to evaluate the chemical element *** experimental and simulation results show that the local variations of chemical compositions exist and play a critical role in the deformation partitioning and mechanical *** high strength and good plasticity of HEAs are obtained via tuning the chemical element distributions,and the optimal elemental anisotropy factor ranges from 2.9 to 3 using machine *** trend can be attributed to the cooperative mechanisms depending on the local variational composition:massive partial dislocation multiplication at an initial stage of plastic deformation,and the inhibition of localized shear banding via the nucleation of deformation twinning at a later *** the new insights gained here,it would be possible to create new metallic alloys with superior properties through thermal-mechanical treatment to tailoring the chemical element distribution.

在城区化过程中,由于人口快速成长且集中,随之而来的建筑物、道路等不透水面密度增加,导致地下水补给减少及破坏水文循环。为了解土地利用方式改变对长期水文量影响,建立一个适宜的城区水循环模式是非常重要的。选定台湾台北的六馆抽水站集水区进行分析,模式参数经过敏感度分析、率定与验证。采用改变不同透水铺面设置比例的方案,评估其对径流量、入渗量、蒸发散量的改变。并分析设置不同比例屋顶雨水贮集系统对地表径流量及供水量的改变。所建立的城区水循环模式是评估土地利用改变造成水文量的改变的一个有效工具,并可提供决策者做为城区土地利用决策的参考。

背景尽管有确凿的证据表明社会因素对健康存在影响,但医生是否应该以及如何应对这些影响尚不明确。本研究旨在调查全科医生对患者社会需求进行筛查的情况。方法本项前瞻性观察研究在弗吉尼亚州北部开展。研究对象为来自该地区的12个全科诊所的17例临床医生以及向其就诊的低文化水平和低收入的社区患者。在再次就诊前,患者完成了社会需求问卷调查,内容包括生活质量、教育、住房、经济、药物使用情况、交通、社交、运动及食物获得情况。全科医生根据患者完成的问卷结果对其进行复诊。同时,全科医生学习了一系列的协同服务以解决患者社会需求,并将此当成诊疗任务的部分内容,在每次诊疗结束的时候,把如何得知患者社会需求影响了就医效果记录在诊疗日志里。结果在完成了问卷调查的123例患者中,106例(86%)描述了自身的社会需求,其中71%拥有运动之外的社会需求,但仅3%想要寻求帮助。全科医生表示:了解了患者的社会需求后,其对23%患者的诊疗工作有所改进,对53%患者的了解有所增加,且与这些患者的沟通发生改善;但评估患者的社会需求费力且困难,自身缺乏足够的社会资源来帮助患者解决需求。结论全科医生认为,了解患者的社会需求可以改进其诊疗行为以及与患者的沟通情况。但对患者的社会需求进行筛查是否有益,仍有待更多证据的支持。

目的在基层卫生人力资源不足的情况下，基层医疗医生何时退休的问题越来越受到相关领域的关注。本研究旨在了解基层医疗医生的退休年龄，并与其他专业医生进行比较。方法对2010-2014年美国医学协会（TheAmericanMedicalAssociation）数据库的相关数据进行描述性分析。将2008年数据库中的数据与国家计划（NationalPlan）和提供枚举系统（ProviderEnumerationSystem）中的数据进行比较，计算出单独使用数据库数据时的偏差。以离开临床实践为退休，构建基层医生的退休年龄曲线，并分析不同性别和城乡间医生的退休年龄差异。结果2014年共有55-80岁从事临床实践的基层医疗医生77987例。2010-2014年从事临床实践基层医疗医生的中位退休年龄为64．9（61．4，68．3）岁，所有基层医疗医生的中位退休年龄为66．1（62．6，69．5）岁，各专业医生的退休年龄大致相同。女性基层医疗医生的退休年龄较男性提前1年；而城乡间基层医疗医生的退休年龄无差异。结论基层医疗医生多选择在60多岁退休，不同性别和城乡间基层医疗医生的退休年龄差异较小，表明基层医疗队伍构成不会对未来的基层医疗医生退休率产生明显影响。

针对雨水滞蓄设施在城区减洪之设置方式及容量计算,以就地消减雨洪(On-site Control)及分散配置原则提出设置规划流程与容量计算方式。对于雨水滞蓄措施之减洪机制进行水文分析,并选择台湾台北县汐止地区为算例进行规划。与目前以减少开发增加洪峰量为目的之滞洪设施规划方式相比,本研究提出之规划方式可同时减少开发增加径流峰值与体积,且所需设计容量较少。
