American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

基于电力现货市场仿真的海上风电接入对广东省电力行业碳减排影响评估 [PDF]
为应对全球气候变化,电力行业低碳化能源转型迫在眉睫。针对2019—2028年广东省的能源规划,搭建广东省电力系统简化模型,依据安全约束经济调度原理仿真电力现货市场,评估大规模海上风电的接入对广东省电力行业碳排放的影响。仿真结果表明,按广东省海上风电发展规划接入海上风电后:电力行业总碳排量和系统碳排放强度均有不同程度的降低;海上风电减排贡献百分比逐年提升,最高可达20%;A类机组碳排放量和碳排放强度基本不变;B类机组相关碳排放数据变化趋势与广东省基本一致;对于接入海上风电场的节点 ...

ABSTRACT The infiltration of counterfeit, fraudulent, and suspect items into civil nuclear supply chains, notably within power generation and medical isotope production, poses severe safety and security threats. The ever‐increasing growth in nuclear installations (70 power plants are under construction and another 100 are in the planning stage) and the

从工程技术角度介绍风力发电机的主要设备和电气基本结构、风力发电机典型雷击事故案例,将风力发电机雷击事故分为五种类型,指出叶片轮毂主轴至共用接地装置之间,除一个常态下以金属塔筒为主的低阻抗电气路径外,还有一个690 V电源线路电涌保护器为主的并联高阻抗电气路径,该路径是风力发电机雷击事故的主要原因,地面箱变内的技术错误扩大了设施设备受损范围。电气模型及电路原理仿真计算表明,1 kA的雷击电流通过低阻抗电气路径时,即可导致并联的高阻抗电气路径转变为低阻抗泄流通道。当雷击风机叶片时 ...

Change in cyclone disaster vulnerability and response in coastal Bangladesh
The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face‐to‐face interviews with 362 residents, participant observation, and focus‐group discussions answer a ...
