ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

交联聚乙烯(crosslinked polyethylene,XLPE)绝缘电力电缆在经过长时间运行后会发生水树老化,降低电缆绝缘强度,威胁电力系统的安全稳定运行。笔者设计了一套XLPE电缆绝缘水树修复装置,利用硅氧烷修复液对电缆试样进行了修复工作,详细介绍了修复过程并深入分析了修复机理。然后仿真对比了修复前后不同类型水树区域的电场变化,测试了修复后电缆介质损耗角正切与绝缘电阻的变化趋势,接着对电缆进行了加速水树老化实验,利用光学显微镜观察老化后XLPE绝缘中的水树生长情况。研究表明 ...

通过淋溶和蒸发试验研究了聚合物/膨润土复合材料在土壤中的水肥调控性能。结果表明,聚合物/膨润土复合材料具有显著的保水性能,但要在充分吸水的情况下才能充分发挥作用;与不含膨润土的高吸水树脂相比,含0.5倍膨润土(相对于聚合物)的复合材料在土壤中表现出相近的持水能力;复合材料通过减少水分的流失而达到减少养分流失的目的;膨润土复合材料可明显减少钾的流失。

腹腔镜结直肠癌根治术患者血清CYFRA21-1、CA724水平变化与复发转移的关系
目的探讨腹腔镜结直肠癌根治术患者血清细胞角蛋白19片段抗原(CYFRA21-1)、糖类抗原724(CA724)水平变化与复发转移的关系。方法选取2017年1月至2019年1月重庆市巴南区人民医院腹腔镜结直肠癌根治术患者120例,同期选取体检健康人员120例,所有人员均采用放射免疫法检测血清CYFRA21-1、CA724水平,分析血清CYFRA21-1、CA724水平变化与结直肠癌根治术后复发转移的关系。结果结直肠癌根治术患者血清CYFRA21-1、CA724水平明显高于健康人员 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
