New Phytologist, EarlyView.Design of the VPDrought experiment in a Scots pine (Pinus sylvestris) forest at the Pfynwald research platform. Summary Atmospheric and soil drought are major, yet typically confounded, drivers of tree stress. Rising vapor pressure deficit (VPD) may impair forest function independently of soil moisture decline, yet stand‐scale experimental separation ...

Journal of Critical Infrastructure Policy, Volume 8, Issue 1, Spring/Summer 2027.ABSTRACT Epistemic orphaning, responsibility drift, loss of institutional memory, and non‐stationarity are not new problems in infrastructure governance—they have accompanied long‐life infrastructure throughout its history. What artificial intelligence changes is not the existence of these problems but their scale, opacity, and the structural ...

Rethinking Community Health Worker Training in Indonesia: A Call for Contextualisation
World Medical &Health Policy, Volume 18, Issue 4, December 2026.ABSTRACT Since late 2021, Indonesia's health transformation agenda has called for a more active role for more than 1.4 million health cadres (the local term for community health workers in Indonesia) in primary health care efforts. However, far prior to this agenda, unlocking health cadres' full potential remains an ongoing challenge in the country ...

Latin American Policy, Volume 17, Issue 4, December 2026.ABSTRACT The public budget has been widely used as an indicator of government attention to measure the distribution of government priorities and the dynamics of budgetary changes across policy sectors. Shifting the debate and analytical locus on budget dynamics to Latin America, recent studies have applied the Punctuated Equilibrium Theory to the ...

, 2002 利用在纤维束缠绕时施加张紧力,使得固化成型后的飞轮内部形成一定的预加径向压应力,这是提高飞轮径向强度的有效方法之一。本文基于过盈配合的思想,建立了计算张紧力缠绕导致的复合材料飞轮内部应力和变形的物理模型和方法,并利用叠加原理获得总体应力和总体变形。通过算例分析发现:恒定张紧力缠绕产生的环向应力在半径方向上先减小后增大,径向压应力不断变小;飞轮设计中仅仅依靠张紧力缠绕是不够的 ...
