When and why to give shorebirds a head start
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Using incentive payments to promote human–carnivore coexistence
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

Interface Issues of Inorganic Solid‐State Electrolytes in Secondary Magnesium Batteries
ABSTRACT Solid‐state magnesium batteries (SSMBs) have gained significant attention as promising candidates for next‐generation safe energy storage systems because of the abundance of magnesium (Mg) in the earth's crust, superior energy density, and inherent nonflammability.

为研究雷电流流经输电线路杆塔接地极的冲击特性,运用CDEGS软件仿真分析杆塔接地极在冲击电流作用下的冲击特性。分析水平接地极及四种改进接地极的冲击特性,探讨不同接地极尺寸以及不同土壤电阻率对冲击接地电阻的影响规律。得到接地极长度及半径对水平接地极冲击接地电阻的影响规律,接地极冲击接地电阻随水平接地极长度的增加而降低,但逐渐趋于稳定;同时获得垂直接地极对四种改进接地极的冲击接地电阻特性,为实际工程中采用合适的方法降低杆塔冲击接地电阻提供了参考。

Abstract Short‐term policy (STP) has attracted considerable attention as a form of time‐related public policy and is typically used to solve urgent problems. The objective of this study, which considers STP as policy myopia from an information science perspective, is to discuss the challenges encountered during the STP policymaking process and their ...

US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Finding floral and faunal species richness optima among active fire regimes
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

降低变电站接地电阻,对保障人员、设备安全特别重要,敷设斜接地极是降低变电站接地电阻的重要措施。为确定斜接地极降阻效果,采用CDEGS软件建立仿真模型,分析了斜接地极布置位置、角度、长度、根数等对不同面积接地网的降阻效果和特征,进而确定了斜接地极的布置方式,并将斜接地极与垂直接地极进行对比。结果显示:敷设斜接地极能够有效降低变电站接地电阻,特别是对100 m×100 m以下地网降阻效果较好;均匀土壤中斜接地极降阻效果优于垂直接地极;分层土壤结构中,接地极的降阻效果取决于实际土壤结构 ...

Bipartisan Failures: How Political Agendas Undermine Core Ethical Principles in Emergency Management
ABSTRACT This paper examines how political agendas across the ideological spectrum compromise ethical principles in emergency management in the United States. Through a literature review and comparative fact‐based scenario analysis, it demonstrates that both conservative and liberal governments have politicized disaster declarations, resource ...

垂直接地极的主体是分散的数根或数十根垂直电极,这一结构特点使垂直接地极的埋深问题与传统水平接地极有很大区别。本文首先采用单根电极模型研究了典型土壤模型下埋深对接地极电气性能影响,提出垂直接地极埋深选取的基本原则。由于垂直接地极的电极一般呈椭圆形布置,计算发现最大跨步电势往往出现在长轴端部附近,提出适当增大长轴端部附近电极的埋深改善接地极跨步电势分布特性的思路。最后结合长翠村垂直接地极跨步电势的实测数据和仿真计算结果 ...
