    Cause Analysis and Countermeasures of Through Shakes in Foamed Concrete Subgrade by Xianbin Huang, Chenyang Liu, Yahong Wangren, Mingxing Wang, Yujiao Mei, Zongrong Xie, Man Liao

    Published 2019-01-01
    “…The maximum principle tensile stress of 0.34 MPa also occurs on the top of the simply supported beam when elastic modulus is 200 MPa and 400 MPa, which is greater than tensile strength of foamed concrete of 0.31 MPa and 0.26 MPa at 7 d and 28 d, respectively. Thus, the adoption of a simply supported beam structure fits site through crack. …”

    小鼠心源性CD51阳性细胞的分离与鉴定

    Published 2014-01-01
    “…【结果】实验结果显示小鼠心脏中存在CD51+细胞,随年龄增大其表达水平呈下降趋势;在出生7d C57小鼠心脏组织中可观察到CD51+ 细胞广泛分布于心房、心室;流式细胞仪分选出生7d C57小鼠心脏组织中阳性细胞结果显示阳性率约4%左右;诱导结果显示该细胞可以分化形成骨及脂肪组织,进一步证明其存在多向分化能力。…”
