1The Use of Data Mining Techniques in Rockburst Risk Assessment显示文摘目前在世界范围内的很多地下矿山,岩爆已经成为一个与矿山采矿生产密切相关的重要现象。深入理解这类现象,不仅有助于岩爆管理,而且还有可能节约采矿成本,减少人身伤亡事故。其中,实验室实验是深入研究岩爆机理的一个重要途径。在本文作者前期的研究中,已经建立了实验室岩爆实验数据库。与此同时,借助于数字采矿技术,也建立了岩爆最大应力和岩爆风险指数的预测模型。为实现基于矿山地质条件和矿山井巷建筑结构特性对岩爆类型即岩爆强度等级的准确预测,本文的重点是,基于对岩爆实例的分析来建立岩爆影响矩阵,明确岩爆现象的诱发因子,并厘清这些影响因子之间的相互关系。运用人工神经网络(ANN)和初始贝叶斯分类器等数字矿山技术,对矿山岩爆数据库进行了更深入的研究。最后给出了研究得出的各项结论。Luis Ribeiro e Sousa Tiago Miranda Rita Leal e Sousa Joaquim Tinoco 2017Engineering2017,3,4:6
2Numerical and safety considerations about the Daguangbao landslide induced by the 2008 Wenchuan earthquake显示文摘The 2008 Wenchuan earthquake resulted in a large number of fatalities and caused significant economic losses.Thousands of landslides,many of which are very large,were triggered by the earthquake.A majority of catastrophic landslides were distributed along the central Longmenshan fault system,at the eastern margin of the Tibetan Plateau.Some of the landslides resulted in sudden damming of rivers causing flooding,which in turn induced secondary sliding disasters.Among the most significant landslides,the Daguangbao landslide was the largest in volume with the maximum thickness.For this,a numerical model of the Daguangbao landslide,using the material point method(MPM),was developed to simulate the interaction of the seismic loads imposed on the slope.The numerical results then are compared with the post-earthquake profile.As a consequence of the landslide,a nearly vertical head scarp with a maximum height of about 700 m was generated.This is considered as a high risk situation that requires constant monitoring and evaluation.Finally,we propose a methodology based on Bayesian networks(BNs)to manage the risk associated with the stability of the rockwall at the Daguangbao landslide site.Manchao He L.Ribeiro e Sousa AndréMüller Eurípedes Vargas Jr. R.L.Sousa C.Sousa Oliveira Weili Gong 2019Journal of Rock Mechanics and Geotechnical Engineering2019,11,5:4

4Association of Helicobacter pylori infection and giardiasis: Results from a study of surrogate markers for fecal exposure among children显示文摘AIM: To investigate whether Helicobacter pylori (H pykori)infection is associated with hepatitis A virus (HAV) infection, presence of enteroparasites, and other surrogates of fecal exposure.METHODS: We conducted a cross-sectional study in 121 children consecutively admitted at a pediatric hospital inSalvador, Brazil.H pylori and HAV infection were identified by the presence of serum antibodies. Stool specimens were examined for the presence of ova and parasites. A structured questionnaire inquiring about sanitary conditions and life style was applied to each subject. RESULTS: Fifty-one of the 121 children (42.1%) werefound to be seropositive for H pylori, and 45 (37.2%) for HAV. The seroprevalence ofHpyloriand HAV both increased significantly with age. Cross-tabulation of data showed that 26 (21.5%) were seropositive and 51 (42.1%) were negative for bothHpyloriand HAV antibodies (χ2 = 7.18,OR = 2.8, CI 1.30-5.97). The age adjusted OR for an HAV-infected child being H pylori positive was 2.3 (CI1.02-5.03). The agreement between H pylori and HAVseropositivity was fair (κ = 0.24). After controlling for possible confounding, the variables remaining independently associated with seropositivity to H pyloriwere age,presence of Giardia lamblia in feces (OR = 3.2, 95%CI, 1.1-9.5) and poor garbage disposal quality (OR = 2.4,95%CI, 1.1-5.1).CONCLUSION: Our data suggest that H pylori infection is associated with surrogate markers of fecal exposure. Thus, we conclude that the fecal-oral route is relevant in the transmission of HP among children in an urban setting of a developing country. The association observed between G. lamblia and H pylori infection may have several explanations. Further studies to investigate this relationship are warranted.Edson Duarte Moreira Jr Victor Bastos Nassri Rafaela Sousa Santos Junísia Ferraz Matos Wilson Andrade de Carvalho Célia Stolve Silvani Círia Santana e Sant'Ana 2005World Journal of Gastroenterology2005,11,18:3
