Abstract During the Great East Japan Earthquake, many people experienced the loss of family and friends, among other traumatic events. This study sought to clarify the impact of the loss of significant close others on posttraumatic stress symptoms (PTSS), as well as the factors associated with PTSS, among individuals who experienced the loss of ...

The changing sociocultural context of wildlife conservation
Abstract We introduced a multilevel model of value shift to describe the changing social context of wildlife conservation. Our model depicts how cultural‐level processes driven by modernization (e.g., increased wealth, education, and urbanization) affect changes in individual‐level cognition that prompt a shift from domination to mutualism wildlife ...

ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

PDC和FDS法的超低频响应对油纸绝缘受潮、老化的诊断具有较好效果,研究表明,油纸绝缘电介质的超低频响应具有明显的弥散现象,针对超低频响应的机理,目前尚未统一定论;文中通过分析载流子在不同频率下迁移速度不同造成的浓差极化,推导超低频激励下油纸绝缘中的内部极化电流函数,并结合载流子移动的统计特性,构建超低频下的介电响应模型,用以解释油纸绝缘电介质响应的低频弥散现象。与实测PDC数据比较认为模型符合实际情况,表明具有统计性的载流子浓差极化可以认为是造成油纸绝缘低频弥散的主要机制。

甲醛,作为一种广泛使用并非常有害的有机废气,已在很多场合对人体健康构成严重威胁。笔者研究利用高频介质阻挡放电技术进行降解甲醛的实验研究,考察了反应器结构参数对甲醛降解率的影响,并对高频介质阻挡放电产生的低温等离子体去除甲醛的机理进行分析。实验结果表明,其它条件稳定不变的情况下,放电极和反应器介质管径变化对甲醛降解率有显著的非单调的影响,对于放电极直径和反应器介质管径应存在最佳尺寸配比,使得甲醛降解率最高;钨丝比铜丝和不锈钢丝更适合作为反应器内部轴线放电极;采用相对介电常数较大的99瓷作为阻挡层介质材料 ...
