Dianci bileiqi, 2018 气体绝缘金属封闭输电线（GIL）因其具有容量大、传输损耗少等优点逐步得到推广,需要分析GIL雷电过电压威胁及其相应防护措施。利用EMTP软件搭建500 k V输电线路和GIL模型,计算线路发生反击和绕击情况下GIL雷电过电压,比较过电压暂态特性差异,分析过电压对绝缘威胁及安装额外金属氧化物避雷器对过电压的抑制效果,讨论GIL上避雷器安装位置对防护效果的影响。分析结果表明:线路发生反击时,GIL过电压波形振荡比绕击时剧烈,但过电压幅值要低于绕击情况。距离雷击点越远,GIL过电压幅值越高 ...

PS: Political Science & Politics, 2010 Gil Friedman, lecturer in political science at Tel Aviv University, passed away on July 16, 2009, at the age of 42 after a short bout with cancer. Much too young, and with so much promise, Gil's death was an unexpected shock to his relatives, friends, and colleagues.

Animal empathy reconsidered: a multidimensional profile account
Biological Reviews, EarlyView.ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Biological Reviews, EarlyView.ABSTRACT Understanding migration ecology is essential for effective conservation of migratory species. To achieve a comprehensive understanding of the ecology of migrating species, it is necessary to study how species react to the complex interplay of intrinsic and extrinsic conditions when optimizing their migratory journey in terms of survival ...

Food‐solicitation displays in nestling birds: still begging for answers
Biological Reviews, EarlyView.ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.
