Evaluating the impact of caribou habitat restoration on predator and prey movement
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Fragmentation of the boreal forest by linear features, including seismic lines, has destabilized predator–prey dynamics, resulting in the decline of woodland caribou (Rangifer tarandus caribou) populations. Restoration of human‐altered habitat has therefore been identified as a critical management tool for achieving self‐sustaining woodland ...

Journal of Traumatic Stress, Volume 36, Issue 1, Page 129-143, February 2023., 2023 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 ...

Journal of Traumatic Stress, Volume 34, Issue 3, Page 512-525, June 2021., 2021 Abstract The 2011 Tohoku earthquake and tsunami in Japan was an extraordinarily stressful incident that caused harmful psychological reactions, such as posttraumatic stress disorder (PTSD), among affected individuals. However, a proportion of exposed individuals experienced posttraumatic growth (PTG), characterized by a noticeable degree of personal ...

Gaoya dianqi, 2021 支柱式电容器塔广泛应用于特高压变电站的交、直流滤波器中,设备质量往往达数十吨,在地震作用下响应十分显著。为研究其地震响应特征,文中以某特高压变电站内支柱式电容器塔为研究对象,首先基于有限元模型,结合模态分析以及动力时程分析发现设备在地震作用下的扭转效应可以忽略,并且其一阶振型响应占据绝对主导作用。在此基础上,选取7条不同场地类型的地震动进行水平双向输入,分别采用基于一阶振型的简化反应谱法以及时程法计算设备的双向地震耦合效应 ...

Dizhen xuebao在分析场地条件对地震震害影响及国内外关于软弱土层对场地地震反应影响的基础上，采用实际含淤泥质土层场地资料，建立了12个含软弱土层的场地模型，在不同输入地震动水平下进行了场地地震反应一维等效线性化分析，讨论了软弱土层厚度和埋深对场地地震反应的影响。结果表明：随着软弱土层的埋深或厚度的增加，反应谱特征周期逐渐增大；输入地震动峰值增加，反应谱特征周期亦增大。继而依据软弱土层厚度、埋深及输入地震动强度对场地加速度反应谱特征周期的影响特征，提出了含软弱土层场地地震动加速度反应谱特征周期调整方法。

硬管母线连接的1000 kV复合外套避雷器和互感器地震模拟振动台试验研究
Gaoya dianqi, 2022 为研究地震作用下硬管母线连接的特高压复合外套电气设备的地震效应,依据特高压电气设备抗震试验方法进行了硬管母线连接的1 000 kV复合外套避雷器和互感器组成的互连结构体系的地震模拟振动台试验。通过白噪声扫频及标准时程波地震试验,测定了设备的自振频率以及关键部位的应变、加速度响应。试验结果表明:互连结构体系沿管母轴线方向的耦合效应强于垂直管母轴线方向;输入目标峰值加速度越大,互连结构体系的非线性特性越明显;沿管母轴线方向的地震波激励引起的扭转振动中互感器设备的地震响应较为显著 ...
