Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Gaoya dianqi, 2018 空气间隙的放电特性是特高压输电线路设计的重要指标,沙尘天气会对空气间隙的放电特性产生影响。为更加深入地研究沙尘条件下空气间隙的放电特性,文中针对弥漫沙尘的棒—板空气间隙的电场分布进行了仿真。仿真考虑了间隙中弥漫沙尘时介质的不均匀性,建立了三维仿真模型,改进了以往改变介质介电常数模拟介质特性变化的方法。根据电场仿真的结果,沙尘分布于间隙中时,沙粒周围电场出现了明显的畸变。沙粒周围电场升高的方向总是指向棒极末端的方向,而在沙粒与棒电极连线的垂直方向上电场降低,该方向的电场值低于周围区域 ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...
