ABSTRACT Climate disasters are currently changing territory around the world by showing large inequalities that exist in infrastructure systems, governance arrangements, and development pathways. In many cases, climate risk response strategies like managed retreat have been framed as practical approaches to respond to increasing climate disasters ...

ABSTRACT The realization of bifunctional perovskite devices integrating photovoltaic (PV) and light‐emitting diode (LED) capabilities requires precisely controlled grain architectures to facilitate dual carrier transport pathways. In this work, sulfaguanidine (SG) molecules were introduced into the perovskite solution to reconstruct the crystallization

污秽分布对陶瓷XP-70与玻璃LXP-70绝缘子放电影响的实验研究
基于绝缘子污秽分布的非连续特征,开展了非连续污秽分布对陶瓷XP-70与玻璃LXP-70绝缘子交/直流放电影响的实验研究。首先,基于紫外脉冲原理搭建了污秽绝缘子放电紫外脉冲检测系统。在此基础上,研究了非连续污秽分布对绝缘子交/直流放电紫外脉冲与泄漏电流的影响特性。试验结果表明:非连续污秽分布下陶瓷绝缘子交流放电紫外脉冲数高于全污秽绝缘子放电紫外脉冲数。全污秽陶瓷绝缘子直流放电紫外脉冲数明显高于其它污秽分布下绝缘子放电紫外脉冲数。玻璃绝缘子不同污秽分布下交/直流放电紫外脉冲数在不同电压等级下表现出较大差异 ...

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 ...

国内连续管作业机虽然已经有了较大的发展,但是国内开发的相关软件功能模块比较单一,大部分连续管作业配套软件基本依靠国外公司开发的相关产品。介绍了4种国外连续管作业软件现状,并对其软件架构进行深入分析,认为一个完整的综合作业软件应该有几个应用模块:①数据采集模块。采集并监控作业关键参数,为力学模拟、流体模拟和疲劳评估提供基础数据。②力学模拟模块。对连续管管柱的力和应力进行综合模拟,并由此模拟作业过程中各种因素对作业的影响,可以进行作业前设计或实时监控作业过程。③流体模拟模块。对连续管及井筒内的流体进行模拟 ...

A Multidimensional Operationalization of Policy Change
ABSTRACT Policy change is a core variable of policy process research. Several theories and frameworks distinguish different levels of policy change. These include minor change vs. major change (Advocacy Coalition Framework), incrementalism vs. nonincrementalism (Multiple Streams Framework), punctuations vs.

Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...
