1Comparative stability analyses of traditional and selective room-and-pillar mining techniques for sub-horizontal tungsten veins显示文摘The stability and productivity concerning a modification on the traditional room and pillar for a new selective technique at the Portuguese Panasqueira Mine have been described.The traditional room-and-pillar stoping uses 5.0-m wide rooms with 3.0 m×3.0 m pillars,while the selective room-and-pillar mining technique consists in stoping with rooms of 4.0 m wide and pillars of 4 m×4 m with a subsequent selective cutting of the quartz veins at the mid pillar of approximately 0.5 m high,to obtain a pillar section with an area of 3.0 m×3.0 m.The stability and productivity analyses indicate that the selective technique obtains smaller average pillar safety factor,more rock mass displacement,more extraction and selectivity ratios,and ore grade improvement,compared with the traditional technique.These results show that the selective technique is also more convenient.This proposed selective room-and-pillar mining technique is applicable to any sub-horizontal narrow quartz veins with wolfram,gold,etc.such as the famous La Rinconada gold mine in the Peruvian Andes.Vidal Felix Navarro Torres Carlos Dinis da Gama Matilde Costa e Silva Paula Falcao Neves Qiang Xie 2011International Journal of Minerals,Metallurgy and Materials2011,18,1:7
2成人IDH野生型星形细胞瘤从生物学和临床上归为其他肿瘤类型显示文摘WHO III级的IDH野生型间变性星形细胞瘤预后差。为了对星形细胞瘤进行分子亚组分型或诊断上的重新分类,作者分析160例成人IDH野生型星形细胞肿瘤的分子标志性变异,并行甲基化和拷贝数分析,其中包括120例 WHO III级的间变性星形细胞瘤和40例WHO II级的弥漫型星形细胞瘤。基于分子谱系和标志性变异特征,将这些肿瘤分为四个主要亚型。78%肿瘤诊断为传统胶质母细胞瘤分子亚型。9%为GBM-H3F3A突变(GBM-H3)亚型。8%具有独特的甲基化特征,与GBM-H3-K27相似,但缺乏H3F3A突变,这组肿瘤主要发生在幕下及中线部位,并且预后较好。120例IDH野生型的间变性星形细胞瘤除1例外均可归入上述3种亚型中。40例WHO II级的弥漫型星形细胞瘤中7例具有不同的分子特征,其中6例重新归类为其他不同的低级别肿瘤类型。有趣的是,TERT突变只发生在分子亚型的GBM (78%),且预后不良。 GBM-H3组缺乏 TERT突变,然而其预后更差。David E R Annekathrin K Felix S 李晓玲 王行富 2015临床与实验病理学杂志2015,31,9:4
