Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Trade restrictions are often advocated and implemented as measures to protect wild species threatened by overexploitation. However, in some instances, their efficacy has been questioned, notably by governments in the southern African (SADC) region, which tend to favor a sustainable use approach to wildlife management. We conducted a systematic

Integrative Conservation, Volume 3, Issue 4, Page 294-311, December 2024.Freshwater biodiversity in China is threatened by multiple anthropogenic factors, and while there are some reasons to suppose it may be possible to bend the curve of biodiversity loss, the variety of threats and their likely interactions with ongoing climate change provide little basis for optimism. For example, the historic overexploitation of Yangtze

Gongye shui chuli, 2013 火电厂将循环排污水回用作锅炉补给水已成为一种趋势,但水源的改变严重影响了反渗透膜系统的正常运行。反渗透膜系统的停机保护作为控制整个反渗透膜系统微生物浓度水平的重要组成部分,尤其是对遏制反渗透膜内的微生物滋生具有很好的针对性和效果。将以异噻唑啉酮为主杀菌保护剂的停机保护方法应用于北京高井热电厂,结果表明,实施保护后的反渗透膜系统运行时间得到延长,制水量显著提高。

Conservation Biology, Volume 38, Issue 6, December 2024.Abstract Human–wildlife conflict (HWC) is a critical challenge to human development and well‐being and threatens biodiversity conservation. Ideally, HWC mitigation should benefit both wildlife and communities and limit the costs associated with living alongside wildlife.

Dianci bileiqi, 2016 在大型建筑楼宇电气系统中,需要设置电涌过电压保护器（SPD）,对雷电或者其他瞬时过压的电涌进行保护。传统的建筑电气SPD电压保护装置采用本机振荡幅度调制的SPD电压保护器设计,但该设计装置会产生电涌过载失真,误差补偿性能。提出一种基于电压增益分配均衡处理的大型建筑电气SPD电压保护方法。进行了建筑电气SPD电压保护系统的等效电路设计,在SPD电压保护等效电路分析的基础上,构建SPD电压保护电力控制功率放大器,对SPD电压保护中出现较大偏差进行电磁耦合补偿 ...

Evaluating cryptographic vulnerabilities created by quantum computing in industrial control systems
Journal of Critical Infrastructure Policy, Volume 5, Issue 2, Page 88-110, Fall/Winter 2024.Abstract Quantum computing is expected to eventually be able to break the public‐key cryptography algorithms currently used throughout information technology (IT) infrastructure, undermining foundational tools used to maintain information security across the country's critical infrastructure.
