Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

An AC constant current power supply design based on linearity power amplifier [PDF]
, 2008 交流恒流源作为稳定电源的分支有广泛用途，其作为一项技术在电源的研究领域中有很重要的意义。其发展与科技的进步息息相关，在各个国家特别是发达国家的国民经济中占有十分重要的地位。近年来我国检测技术有了较大的提高，但同发达国家的电网检测技术相比，差距仍然很大，存在参数检测精度不高、抗干扰性较差,实时性比较差、电路设计复杂等缺点。针对这些问题，本课题建立了一个以AT89C51单片机为控制核心的恒流源控制系统，该系统具有速度快、精度高、实用性强、电路模块化等特点。 本课题已经顺利完成以下几部分内容： 1硬件控制系统：

Gaoya dianqi, 2018 高耦合电抗器（HCSR）辅助开断并联灭弧室是解决大电流故障开断的一种有效方法。由于SF6电弧自身的负伏安特性会影响并联支路电流的同时过零,增加了开断并联SF6电弧支路的难度,限制了其在高电压领域的应用。结合高耦合电抗器辅助并联支路开断的设计思想,首先利用40.5 kV断路器两柱相同灭弧室,进行了小电流条件下,SF6电弧并联支路开断的试验研究,重点分析了开断电流大小、燃弧时间长短与均流、限流开断特性间的关系。其次,针对80 kA大电流条件下的并联支路开断特性,进行了单分试验的初步研究和验证。结果表明 ...

Governance of Climate‐Induced Relocation in the US: An Exploration of Institutional Complexity
Review of Policy Research, Volume 43, Issue 2, March 2026.ABSTRACT Climate change has and will continue to have a profound effect on both individuals and the communities in which they reside. A pressing question is how communities forced to confront climate‐induced catastrophe—including both rapid and slow‐onset hazards—undertake the decision of how and when to relocate, particularly given the multiple scales
