High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Engineering Geometric Active Sites in Cobalt Spinel Oxides for Energy and Environmental Catalysis
ABSTRACT Cobalt‐based spinel oxides (Co3O4 and derivatives) are among the most promising transition metal oxides for electrochemical energy conversion and environmental catalysis due to their abundant active sites, structural tunability, and robust redox flexibility.

基于Relief特征量优化及SOM网络的断路器操作机构状态评估
为提高断路器操作机构状态评估的效率及准确性,文中提出了采用Relief优化方法对分合闸线圈电流特征向量进行优化及SOM网络对线圈电流样本进行分类的高压断路器操作机构状态评估方法。仿真研究结果表明:基于Relief的分合闸线圈电流特征向量优化方法和SOM网络分类方法的操作机构状态评估能够实现操作机构状态的准确评估,同时采用优化后的电流特征向量数据进行状态评估减小了运算量和缩短了运算时间,提高了断路器机构状态评估的效率。

A survey of demanding for learning of “Health Assessment" of clinical nurses
[目的 ]了解不同资历护士对《健康评估》课程及各知识模块的学习需求。 [方法 ]对来自 17家医院的 78名专科升本科护士 ,通过填写问卷 ,对构成《健康评估》课程的体格检查理论与技能、心理社会评估和功能性健康形态 3个知识模块的学习需求进行调查。[结果 ]绝大部分护士均对《健康评估》课程有较高的学习兴趣 ,除具有较高职务的护士在学习心理社会评估知识的兴趣明显高于低职务护士外 ,其他方面均无差异。 [结论 ]有关健康评估的知识仍是临床护士感兴趣的学习内容。

Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

综合考虑复合绝缘子在运行中表现出来的各种老化特性,客观评估其老化程度是保障复合绝缘子安全运行的关键。为此,提出一种复合绝缘子的老化评估模型,将复合绝缘子试品的外观检查试验、憎水性试验、红外测温试验结果作为评估模型的输入参数,对复合绝缘子试品进行老化评估,发现2号复合绝缘子老化程度最重,建议退出运行;1号复合绝缘子老化程度最轻;而3号复合绝缘子老化程度一般,需要跟踪监测。最后通过扫描电镜试验和傅里叶红外光谱试验,验证了评估结果的正确性,说明文中提出的评估模型对于复合绝缘子的老化评估具有一定的意义。

Lessons learned from screening potential other effective area‐based conservation measures
Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
