Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Dianci bileiqi, 2019 输电线路风偏事故频繁发生,对线路正常运行危害极大,尤其在大风天气下经常会造成风偏闪络事故,输电线路的风偏角监测在维护线路正常运行中起到很重要的作用。以一仿真实验为例,对某特定型号的导线和绝缘子进行绝缘子风偏角进行仿真得到动态风偏角与速度关系的表达式,探究不同风速不同覆冰条件下动态与静态风偏角的关系,利用静态风偏角与动态风偏角的关系和动态风偏与速度的关系,有了静态风偏角和风速便可对进行动态风偏中的参数进行估计,从而得到动态风偏的计算表达式。结果显示,该方法可以计算全线的绝缘子串风偏角 ...

Weaving knowledges to support wildlife health surveillance in Kenya's pastoral rangelands
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In wildlife–livestock–human interfaces, pathogens capable of spreading between wild and domestic animals and humans have important implications for conservation outcomes, economics, and public health. Robust wildlife health surveillance can help address these risks.

Gaoya dianqi, 2018 传统风偏角的计算模型没有考虑气象因素对空气密度的影响,文中分析了气象因素对风偏角的影响,提出了基于气象的风偏角计算模型,提出了2种分析风偏角与气象要素关系的数学模型。最后通过气象实例数据,对风偏角进行了仿真计算,并用数学模型对风偏角及其影响因素数据进行了建模分析,同时对风偏角进行了预测。结果表明,风速、风向、相对湿度、气压、气温是影响风偏角的主要气象因素,提出的数学模型能较好地分析了风偏角与其影响因素之间的关系,并且具有较高的风偏角预测精度。

Dianci bileiqi, 2017 通过一起750 kV输电线路风偏跳闸事故,首先采用解析法对杆塔风偏后电气间隙距离进行了计算,得出引起跳闸的危险风偏角。然后根据规程法对风偏角进行了计算,计算结果表明,31 m/s设计的杆塔风偏安全裕量不足,其裕量仅为5°,在1.1倍设计风速下就会发生风偏闪络。最后根据现场在线监测装置监测风速的标准风速和极大风速进行对比,认为引起输电线路风偏跳闸的原因主要是极大风速。对于需要进行防风改造的杆塔,分析了各种防风偏措施及其适用范围,建议采用加装防风偏拉线的解决措施,以提高输电线路的抗风能力 ...

Latin American Policy, Volume 16, Issue 4, December 2025.ABSTRACT In recent years, video assistant referee systems have been increasingly used to correct unfair decisions in sports. Similarly, I argue that constitutional referendums play a corrective role in hybrid or competitive authoritarian regimes, where the electoral referee is biased and the government enjoys unfair advantages.
