Most basal-like breast cancers(BLBCs)have a poor prognosis and high crossover with triple-negative breast cancers(TNBCs).However,approximately 50%of TNBC patients develop chemoresistance.^(1) Dexamethasone reportedly induces Krüppel-like factor 5(KLF5)and can cause docetaxel and cisplatin resistance in TNBC.A super-enhancer can maintain the transcription of KLF5.

针对既有外来校长更替适应研究主要关注"做什么"的问题,本文基于一位校长的案例研究,在"适应行为"基础上进一步讨论了"适应方式"的问题。基于访谈等证据资料的分析显示,不存在完美或固定的适应行为方案。虽然与既有研究证据相比,案例校长在个人定位、领导实践、变革取向和角色社会化等适应行为上存在不同或不足之处,却同样有效适应了新学校。这表明,有效适应中"做什么"并不是唯一重要的,"如何做"也很重要。外来校长的适应效果与适应行为有关,也与适应方式有关。案例校长的有效适应,很大程度上便得益于选择了"优势为本"而非"克服缺陷"的适应方式。这些发现具有实践上的应用和研究上的指导价值。

为研究高强度调浆对高灰细粒煤泥浮选效果的影响,以高灰细粒煤含量较高的炼焦配煤入浮煤泥为研究对象,在粒度分析的基础上,采用接触角试验、煤泥浮选试验等,对高强度调浆时的煤泥浮选效果、不同调浆强度下各粒级浮选精煤灰分组成及强调浆作用下煤泥疏水性变化规律进行了研究。研究结果表明:高强度调浆通过提升微细粒与药剂间的碰撞概率增大了低灰细粒级煤泥接触角,促进了浮选过程中低灰细粒级煤泥的上浮,同时能抑制高灰细粒煤泥的非选择性上浮,从而提高浮选精煤可燃体回收率,降低浮选精煤灰分,提升浮选效率。该研究可为高灰细粒煤泥浮选效果提供有益参考。
