ABSTRACT For over 30 years, the northern Mexican state of Chihuahua bordering Texas and New Mexico has experienced and witnessed multiple forms of violence across its rural and urban regions. Communities are besieged with cartel and gender‐based violence and the saturation of international corporations that pay less than livable wages for workers in ...

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English
ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

分析了城市中低压配网的接地拓扑结构,研究了10 kV配网中性点经小电阻接地后的380V侧接触电压隐患以及安全条件。针对单台区独立式和多台区互联式的台区接地方式,依据相关标准和典型设计分别建立场路模型,开展了台区单相接地故障时的接触电压安全性及影响因素仿真研究。结果表明:1)对于单台区独立式的台区接地方式,保护接地与工作接地的最小分开距离受接地电阻和重复接地影响;2)对于多台区互联式的台区接地方式,最小互联台数与台区间距离、重复接地密切相关。

目前国内500 k V及以上交流超、特高压输电线路大多采用一根钢绞线(GJ地线)和一根光纤复合地线(OPGW)的架设方式。多采用GJ地线分段绝缘、一点接地,OPGW逐塔接地的方式。实际运行经验表明,GJ地线分段绝缘、一点接地不仅电能损耗小,而且并不降低地线的保护性。而OPGW逐塔接地的接地方式在保证通信连续的同时带来地线环流大、电能损耗较大等问题。因此,需要对地线不同接地方式下的感应电量的影响因素进行深入研究。本文以浙江一条运行中500 k V交流输电线路为研究对象,运用电磁暂态计算程序EMTP ...

Abstract The current body of multidisciplinary literature on crisis management still has some unresolved problems. This paper focuses on the following four “controversial issues” in dealing with crises: the usefulness of emergency plans; early signal detection; decision‐making amid high uncertainty; and the centralization/decentralization dilemma.

不同接地方式下变压器35 kV绕组外部过电压特性分析及防治措施
变压器35 kV绕组中性点接地方式较多,现有设计没有对不同接地方式下变压器的防雷措施进行专门考虑,导致变压器35 kV侧雷击事故频发。为了对不同接地方式下变压器35 kV绕组雷电侵入波特性及防治措施进行研究,采用电磁暂态分析软件ATP-EMTP建立仿真模型,对35 kV绕组星形接线的配网变压器和三角形接线的风电场升压变进行了雷电侵入波电磁暂态仿真,分析了导致35 kV绕组绝缘损坏的雷电侵入波特点,考察了不同安装方式下避雷器对雷电侵入波防治的有效性。研究表明不同接地方式下变压器35 ...
