简介:在从Libixia节的Jialingjiang形成的破裂的大多数静脉mineralsdeposited,Hechan区域包括大量僵绳白云石和伴随的天青石,方解石和荧石。这研究分析了性质,来源,由飞机光岩相学的液体的进化,液体包括方法,阴极射线发光图象,和稳定的同位素的作文。在白云石的二阶段的水的液体包括的homogenization温度在100和270°C之间变化。与δ18O数据,为破裂屑的降水负责的液体有δ18在10‰之间的O值并且18‰(相对降雪)。僵绳白云石和伴随的矿物质是在提高的温度的稠密的盐水的活动的结果。而且,液体从导出水兵的盐水的混合物被导出并且更深传播的分析表演流动。这液体在成岩作用期间在Sr被充实并且在骨折并且为地区性的矿化作用形成了天青石。僵绳白云石的溶解被归因于冷却Mg/Ca-decreased液体,它可以联系到一在包围碳酸盐石膏沥滤到天青石。

简介:瞄准:为了学习流行和风险因素,与人的免疫不全与三倍的感染联系了在一张城市的诊所人口的病毒(HIV)/hepatitisB(HBV)/hepatitisC病毒(HCV)。方法:5639个病人的回顾的图表评论在纽约城市里在圣卢凯斯鲁塞韦尔特医院HIV诊所(全面照顾的中心)列在后面,从1999年1月的美国到2007年5月。下列人口统计的特征被分析:年龄,性别,种族和HIV冒因素的风险。多重逻辑回归分析被执行在这些病毒的获得上评估人口统计的因素的影响。结果:HIV/HBV,HIV/HCV和HIV/HBV/HCV感染在252/5639(4.47%)被检测,1411/5639(25.02%)和89/5639(1.58%)病人分别地。HIV/HBV合作感染与男性被联系(或1.711;P=0.005),黑色跑(或2.091;P<0.001),人与\O性交人(MSM)(或1.747;P=0.001),静脉内的药使用(IDU)(或0.114;P<0.001),IDU和异性爱的活动(或0.247;P=0.018),或未知(或1.984;P=0.004)。HIV/HCV合作感染与男性被联系(或1.241;P=0.011),黑色跑(或0.788;P=0.036),MSM(或0.565;P<0.001),IDU(或8.956;P<0.001),IDU和异性爱的活动(或9.106;P<0.001),IDU和MSM(或9.179;P<0.001),或输送(或3.224;P<0.001)。HIV/HBV/HCV合作感染与男性被联系(或2.156;P=0.015),IDU(或6.345;P<0.001),IDU和异性爱的活动(或9.731;P<0.001),IDU和MSM(或9.228;P<0.001),或未知(或4.219;P=0.007)。结论:我们的学习证明有HBV/HCV/HIV的合作感染显著地与IDU被联系。这些结果加亮需要加强教育和综合照顾的最佳的模型,特别地为有IDU的人口,到减少病毒的传播的风险。
