Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

为了检验张力腿(tension leg platforms, TLP)漂浮式海上风电机组利用锚泊系统作为自然接地体的可行性,在CDEGS软件中建立了机组的接地体模型进行接地仿真试验,并模拟了海水电阻率、海水水位、海床土壤电阻率、海底锚固基础尺寸、张力腿数目等因素对接地电阻值的影响,仿真试验验证了当各个影响因素在最恶劣的情况下也能保证机组接地电阻值符合GB/T 50065-2011中的相关规定,证明了张力腿漂浮式海上风电机组利用锚泊系统作为接地体具有可行性。

Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

Abstract Mangrove forest is an ecosystem‐based solution for disaster risk reduction in the Philippines, but its historical deforestation has hampered its capacity to protect coastal communities. With the increasing occurrence of storm surge in the Philippines, mangrove reforestation projects have received renewed attention, but many have failed ...

海上风力发电产业的蓬勃发展面临日益严重的雷电灾害威胁,为有效指导海上风电机组的雷电防护研究,需要研究海洋环境对海上风场接地系统雷击特性的影响。利用PSCAD软件搭建简化海上风场模型,讨论海洋土壤分层环境下上层海水深度和下层土壤电阻率对风机接地系统雷击暂态响应的影响,分析增加接地体长度对于降低暂态过电压的效果。仿真结果表明:风机遭受雷击后,浪涌会传播至其他相连风机,距离雷击点越远的风机,塔底暂态电位幅值越低。下层海床土壤电阻率越大,风机塔底暂态电位幅值越高。上层海水深度越大,风机塔底暂态电位幅值越小 ...
